Android :: Fill_parent With ListView Cells - Single TextView Span One To Two Lines

Feb 12, 2009

I am having this issue where I am trying to have a single TextView span one to two lines, fill the cell completely (so you can also click edges of the cell and it will trigger) and center-align.

This is the layout for the cell:

CODE:...

However cells seems to be filled correctly ONLY if it happens to wrap around and end up spanning two lines of text. It shows center-aligned and you can click anywhere in the cell to trigger the click. The cells that do not span multiple lines of text are left-aligned and trigger (highlight) only if you click where the text is. There is a "numb" area which does not react to clicks inside the cell if the text is short.

Android : How To Get A TextView To Span Length Of Screen

Jan 18, 2010

I've a textview I want to span almost the length of the screen, then 2 buttons at the bottom.

Right now I'm using a relative layout with a textview and two buttons and I can almost get it the way I want but the only thing is the textview isn't as long as I want it. I want it to be as long as necessary for whatever handset is using it. So a constant pixel amount is out.

Android :: RelativeLayout Fill_parent Unexpected Behavior In A ListView With Varying Row Heights

Apr 29, 2010

I'm currently working on a small update to a project and I'm having an issue with Relative_Layout and fill_parent in a list view. I'm trying to insert a divider between two sections in each row, much like the divider in the call log of the default dialer. I checked out the Android source code to see how they did it, but I encountered a problem when replicating their solution.

To start, here is my row item layout:

CODE:..........

The issue I'm facing is that each row has a thumbnail of varying height (ImageView01). If I set the RelativeLayout's layout_height property to fill_parent, the divider does not scale vertically to fill the row (it just remains a 1px dot). If I set layout_height to "?android:attr/listPreferredItemHeight", the divider fills the row, but the thumbnails shrink. I've done some debugging in the getView() method of the adapter, and it seems that the divider's height is not being set properly once the row has it's proper height.

Here is a portion of the getView() method:

CODE:.........

The rest of the method simply sets the appropriate text and images for the row.

Also, I create the inflater object in the adapter's constructor with: inflater = LayoutInflater.from(context);

Am I missing something essential? Or does fill_parent just not work with dynamic heights?

Retrieve And Set ListView Items (cells) Height Depending On ListView Height

Apr 4, 2012

I have some class LoginActivity.java. In the onCreate method I retrieve ListView:

ListView list = (ListView)findViewById(R.id.snListView); then:

list.setAdapter(adapter);

In addition there are login.xml layout - there are:

<ListView
android:id="@+id/snListView"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
and sn_row.xml:

[Code]...

At the moment I have cell's height 100dp, I need that cell's height will depend on device, I mean I have here 5 cells showing at login screen in ListView and I need that these 5 rows will fit the ListView (cell's height = ListView's height/5).

Android :: Center A Title In A TextView With 2 Lines?

Aug 11, 2010

I know how to center the text in the TextView and how to center the TextView inside its parent layout, but what I'm looking for is how to center a title (text centered but second line starting at the same point).

What I'm looking for is this:

| Centered |
| right! |

or this:

| Center |

Not this (text centered):

| Too |
| centered! |

or this (TextView centered):

|Centered |
|wrong! |

or this (with padding and left):

| |Also | |
| |wrong! | |

Did anyone understad this? Is it possible to do this without coding the String itself?

Android :: Updating Single ListView Element?

Mar 29, 2010

In the application I am working on now I came up with the following problem. I have list view which is displaying items with images in most cases it will be different image for different items (thumbnails about 60x60 pixels). So the problem is how can I handle image processing for the view. For know I have the following variants:

1. I can cache all bitmaps and when I try to display view I get bitmap from cache synchronously and display it. The problem is that 60x60=3600x4=14kb per bitmap which is waste of resources.

2. When I need to display view I can register event to some thread to decode the associated bitmap which will decode it in background and than to update gui. This sounds good for me the scrolling is still smooth because all image processing is done in background. Updating list view is bit jerky for now I am doing it view notifyDataSetChanged which is updating all visible views although I can update thumbnail for a single item.

So question one is is there better way the update single listview element than calling notifyDataSetChanged.

ListView Seems Only To Work With A Single Column

Oct 21, 2011

I am new to android development and have been tasked with developing an app. One of the screens will require there to be a list of people with some thumbnail information about them, similar to:

Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
[code]....

This information will be stored in an SQLite DB. Now I can see that listView seems only to work with a single column. What is the best way to go about this?

Android : Want To Implement App On ListView Instead Of TextView

Jul 2, 2010

In my project whenever I extend activity it works fine but as soon as I extend ListActivity it throws exception and shows file not found. Why is that? We already know that ListActivity itself extends the Activity class. The application must run fine.

Here's the java file:

package com.android.feedGrabber;

import java.net.URL;
import java.net.URLConnection;
import java.util.Collection;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

import com.sun.cnpi.rss.elements.Item;
import com.sun.cnpi.rss.elements.Rss;
import com.sun.cnpi.rss.parser.RssParser;
import com.sun.cnpi.rss.parser.RssParserFactory;

If I change "extends Activity" to "extends ListActivity" it gives the exception. I need to bring this change because I want to implement it on ListView instead of TextView.

Error it throws:
debug mode gets active and it highlights under Suspended(exception RunTimeException): ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2663.

Android :: Setting TextView Properties In A ListView

May 20, 2010

I have an activity with a ListView which is populated through a custom ArrayAdapter. There is an array of objects which have a Boolean property called 'isRead'. Based on the value of this property, I want to set the typeface of one of the TextViews in the row to either 'normal' or 'bold'. I also set the color of the text to either 'gray' or 'black When the Activity initially starts up, everything works as expected. If isRead is true, the text is gray with a normal font. Once I scroll down the list and then scroll up again, the text of an object where isRead is true is colored gray, but the font is bold. Code...

Android : Get A ListView And TextView To Scroll As One Unit?

Oct 11, 2010

I have a main menu screen with a simple ListView that contains "links" to further screens in my app (Browse, Bookmarks, Settings, About, etc.). Underneath the ListView there is a TextView (more accurately, a TextSwitcher that rotates TextViews) that changes every 10 seconds to display a new "tip".

In portrait mode, this works fine. There are my five list items in the ListView , and my tip label underneath. However, when I switch to landscape mode, the ListView is taller than the screen. The ListView scrolls normally, but I cannot scroll past the end of the ListView to see the TextView underneath.

I have tried every possible combination of Layouts, wrappers, ScrollViews, and layout_height parameters and I simply cannot get it to behave.

Here is the simplest code ...

Like I've said, I've already tried so many different combinations that I can't list them, and for the most part I was randomly inserting XML in an attempt to get something to work the way I wanted. So I'd greatly appreciate suggestions as to how I would go about doing this the right way.

Android :: Fail On Trying To FindViewById For Nested TextView - Within ListView

Jul 31, 2010

Trying to have a ListView (scrollable list) of rows made of two TextViews. I have a list of items from a database that I want to populating into the LinearLayout->ListView->TextView but can't get to the id...

Layout somewhat like this instructional link, but have backed away from RelativeLayout and using LinearLayout to get it working. Not even worried about how it looks yet; just can't get it wired together yet.

http://android-developers.blogspot.com/2009/02/android-layout-tricks-1.html

Have two XML files (very abbreviated details below)

CODE:...........

I have an ArrayAdapter where I inflate the stuffView. My thinking and understanding of other examples is it's not inflated (this nested stuffView) until I purposely inflate it. That all works fine but when I do the findViewById it returns null and thus I can't setText().

epic Fail due to complete ignorance/newbieness on my part. Note: I've pored through what I can of Reto's book, especially a simliar example on Page 163 but fail fail fail...

Can some kind soul point me in the right direction?

Must I inflate this nested view? (Reto's example does). If so, what am I missing? I'm hoping someone can point me to a better example.

My code's probably too involved at this point to post and a bit proprietary.

CODE:........

A pojo called Thingy (not copying Thingy.java here - very simple)

The main class:

CODE:...........

So this code is in essence what I'm looking for help on; neutered the names to call it Thingy.... This sample isn't triggering the getView(). That's a secondary problem I have to sort out. More importantly, your help on the findViewById failure and if I've got the XML right would help a bunch.

Android :: HTML Links In A TextView Inside A ListView

Jan 29, 2009

I've got a ListView where each item in the list is contains several controls. One of the items is a checkbox, and I can check/uncheck it without problems. The other items are some TextViews and a WebView. I've got autoLink turned on and linksClickable turned on, but I can't get links to fire up the browser when I click on them. This applies to both TextView and WebView. I've tried changing the parent to a GridView instead of a ListView, playing with setFocusable(), and all that, but to no avail.

Is it even possible to have interaction on the TextView-based elements of a row in a ListView? It seems like that *should* be possible, but I've been banging my head against this problem for a few weeks with no progress. What's the secret?

Android :: Dynamically Change Text Color Of A TextView Inside A ListView

Nov 18, 2010

I'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.

Right now I'm essentially using the Hello ListView code to create my ListView.

(In constructor)

CODE:...........

Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:

CODE:.............

This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.

Android :: Use Custom Color For Each Textview In Listview That Extends SimpleAdapter In Droid?

May 31, 2010

I have a listview with custom rows and that extends SimpleAdapter.
Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation.
Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row.
To put it as simple:
each listview item has some custom colors the value of which comes from the hidden field.

I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it).

Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other?

Android :: Android ListView Does Not Listen On Single Clicks

I'm developing an simple application on Android, where some items are shown on a list. The user may click on one, taking him to a further activity.But my OnItemClickListener does not get called! I've found this very similar question, but the solution (disallow the list item view to get focus) does not work for me. However, a long click gets catched my OnItemLongClickListener gets called. Please have a look at the following code and try it yourself. This is a simplified version of my code, showing the buggy behavior. Btw: I'm using Andriod SDK 2.0 with Eclipse 3.5.1.

Replace Single Row View In Custom STATIC ListView - STATIC Data

Mar 18, 2013

I have Eclipse Juno and I'm working on an app with that.

The main activity will have a scrollable menu that takes you to all the other activities.

So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.

Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)

- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.

- Item ??: Centred, bold, non selectable title (Tools)

- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.

Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.

I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.

I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.

I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C
