Android :: ListView With TextView With Background Image
Nov 12, 2010
I have a ListView with a lot of "rows". In each row, i have one TextView with a background image. When i scroll, the images of the rows mixes... they jump to another row with the scroll.
In have tried android: scrollingCache="false" and android:cacheColorHint="#00000000" but nothing.
The images are loaded dinamically.
Part of my layout:
CODE:.........................
And part of my code:
CODE:............
"avatars" is a cache of Drawables. any idea?

I have a situation where I am using a TextView with an image and would like to set a background on just the text part. When I use android:background it sets the background behind both the text and the image. Is there a way to have it just put the background behind the text without me having to tear apart my layout and use a separate ImageView with the TextView?

I'm battling with extending a TextView for my Android app. I'd like to create "bubbles" to display text messages in a conversation, similar to the native iPhone SMS conversations.
Is there a way to implement the resizing of a background image without just stretching it? I'd like to have a single background image that keeps it's corners but get stretched only in defined areas. I think this should be possible because I've seen it in a SMS app, but I wonder how to implement that.

ListView Question! I know it's possible change the row color, but it's possible to put some imagem on background? And if yes, it's possible to create an imagem 1px and repeat-x or repeat-y like CSS?

Can you please tell me how can I place an background image to a the left upper corner of TextView in android? I would like the image not to be scaled by android.
I have tried
Resources res = getResources();
setCompoundDrawables(res.getDrawable(R.drawable.icon48x48_1), null, null, null);
Nothing is shown.
And I have tried
setBackground(R.drawable.icon48x48_1);
But it stretches the image.

I am developing an android application where I need to manipulate the background image of the rows in listview on certain conditions. Initially when the listview is loaded all works properly. But when I scroll down to the listview and come up again the background image changes. Can someone tell me the reason why its happening so? Hope to get the reply soon.

I am loading a listview dynamically. I have set a .9.png image as row background image. The main purpose of using .9.png image was to extend the height of the image dynamically according to the contents of the listview. But, the image is not getting extended. The contents which can be displayed within the height of the row are being displayed and the rest are being cut.

I have a TextView that I created in the main.xml. In my app.java I am dynamically positioning that TextView based on where the user taps the screen. The problem I am having is that when I call myTextView.setPadding(100,100,0,0), it moves the actual Text of the TextView, but does not move the Colored Background of the TextView.

I'm attempting to change the background color of an Android TextView widget when the user touches it. I've created a selector for that purpose, which is stored in res/color/selector.xml and roughly looks like that:
CODE:................
The clickable attribute of the TextView is "true", in case that's of interest.
When I assign this selector to a TextView as android:background="@color/selector",
I'm getting the following exception at runtime: ERROR/AndroidRuntime(13130): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable
When I change the attribute to drawable, it works, but the result is looking completely wrong because the IDs appear to be interpreted as image references instead of color references (as the "drawable" suggests).
What confuses me is that I can set a color reference, e.g. "@color/black", as the background attribute directly. This is working as expected. Using selectors doesn't work.
I can also use the selector as the textColor without problems.
What's the correct way to apply a background-color-selector to a TextView in Android?

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.

I have an XMl file like below which I will use to set background for Textview:
row.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
The above Xml I will set as background for TextView in main.xml as below:
main.xml
<TextView
android:id="@+id/rowtext3"
android:text="Availablity"
android:layout_height="25px"
android:layout_width="60px"
android:textSize="10px"
android:textStyle="bold"
android:textColor="@color/black"
android:gravity="center"
android:background="@drawable/row"/>
But I want this to do from code rather than Xml.I have done everything that I have done in Xml like font,width,Height,font dynamically through code , but not able to set Background that I mentioned in Xml file . How can we set content of Xml file as background to textview similar to how we set background as XML in main.xml.
In the code I have done like this:
t1=new TextView(this);
t1.setText(ed1.getText());
t1.setHeight(25);
t1.setWidth(60);
t1.setTextSize(10);
But I didn't find how to set background i.e. how to set XML content as background?

Actually, what I want is a textview which can show the progress of something, I know progressbar in android,however,so far as I know, it can not contain any text(am I right?), so, I want to change the background color of the textview to show progress,from left to right gradually.
Is there any other way to do this?

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...

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.

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.

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.

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?

I'm having a problem with incorporating an imageview with a textview into a list view.
Activity code:
Code:
ListView menuList = (ListView) findViewById(R.id.ListView_Menu);
String[] menuitems = {getResources().getString(R.string.playgamebtn),[code]....
displaying the imageview and the textview isn't the problem it is clicking on it. When clicking on the textview, there is an error with the ArrayAdapter.

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.
