Android :: Dynamically Set EditText Height?

Nov 24, 2010

I want to simply set the height of an EditText component to be 50% of the user's screen height.

I'm creating the initial layout from an xml file (main.xml), loaded in the Activity's onCreate(Bundle). From the xml configuration, I understand how to set the EditText height to a literal value, e.g., android:layout_height="150dip", and from the onCreate(Bundle), I understand that I can call setHeight(int) on the EditText component, but the call to setHeight(int) appears to be ignored, and if I don't have the layout_height setting out of the xml, then I get an exception when my app is starting, complaining that the height value is required (and the app dies).

Is there a way to set the height from the xml based on the user's screen height? In other words, within the xml, is it possible to retrieve the user's screen height and use it to calculate a value for a component?

(I'm placing the EditText in a LinearLayout with vertical orientation.)

Android :: Dynamically Extend The Height Of ListView Row Background Image

Apr 23, 2010

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.

Android :: Adjust Height Of Group Headers In An ExpandableListView Dynamically?

Oct 7, 2010

I have an ExpandableListView (ELV) with the groups having LinearLayout. I have set the height of the group to some value (38dip in this case, equivalent to two lines of text). If the group heading is long and would take more than 2 lines, it is not shown properly in the ELV item - some part of the view gets scrolled. On the other hand, if I change android:layout_height to "wrap_content" in the LinearLayout, the groups always show all the lines. But the line widths are variable, i.e., short titles show up with only 1 line and long titles show up with 2, 3 or 4 lines. That looks ugly. I would like to implement the height to be something like max("38dip", "wrap_content"). Is there a way to do this?

Even programmatically, I do not seem to be getting the actual height of the group if I set android:layout_height to "wrap_content". Any suggestions there?

Android :: Getting The Height Of A TextView

Sep 18, 2010

I have a TextView where I have called setText() and setWidth(). This causes the text to wrap and the view to grow longer with more text, which is what I want. But I have some other graphics that I want to position relative to the resulting height of the TextView. I tried calling getHeight() (after setting text and width) and that method returned 0. So how can I find the height of the TextView?

Android :: TextView Height Not Collapsing

Sep 30, 2010

I have TextViews in a View that are dynamically populated. But even when there's no text in them they still seem to take up space, specifically height, even though the TextView and the parent have layout_height set to wrap_content. Coming from HTML land, I would expect them to collapse. Even if I set them to invisible, they still take up room. I've tried a LinearLayout and a RelativeLayout. How exactly do you get them to go away without removing them altogether?

Android : Changing Text Value Of A Textview Dynamically

Nov 9, 2010

I have a textview in my XML layout file, but when I try to change its text value with code pragmatically (dynamically, depending on which button the user clicks) then the text of the textview doesn't change.

This is the code that I tried:

TextView userText = (TextView) findViewById(R.id.User);

userText.setText(bundle.getString("user"));

In debug mode, I can see that usertext has the changed text, but the change doesn't appear on my mobile window... I don't know why.

EDIT: SOLVED! it was a problem with my relative layout, text is out of the window!

Android :: Setup Background Of A TextView Dynamically From Xml File?

Oct 10, 2010

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?

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 : Min Height Fill_parent And Height Wrap_content In ScrollView - Or Just The Email App Compose Layout's Code

Oct 7, 2010

If I have the following:

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

How can I get the body (second EditText) to fill the rest of the screen, but still have the scrollview kick in when the contents of the body are too long? Like a height="wrap_content" and minHeight="fill_parent"

layout_height="fill_parent" seems to not do anything if you put them in a scrollview

A working example of what I want is the email app compose window

I tried this and the EditText elements act like they are wrap_content and no filling is happening. Just scrolling if you type enough

Android :: How To Get Button's Height To Match Another Element's Height

Nov 15, 2010

I want to put a button next to a EditText and I want their heights to match.For example, from the built in Android browser:

The Go button is the same height as the EditText field.I know I could wrap both these views in a parent layout view, and set both of their heights to fill_parent, and that would make them match.However, I would like to do this without having to give the layout a static size.I would rather have the EditText take whatever height it needs based on the font size and then have the button next to it match whatever height that might be.Is this possible with an xml layout?

Android : RelativeLayout Height Not Following GridView Height

Aug 28, 2010

I am having problem with a GridView within a RelativeLayout, which is again within a ScrollView. The problem is that the height of the RelativeLayout is not following the height of the contents of the GridView. When there are more than one rows, the GridView is clipped and a scrollbar appears, which is undesirable. I have tried to illustrate my problem using an screenshot from the Android hierarchy viewer. You can see how the red RelativeLayout box has clipped the second row of the GridView. I am pasting the XML layout of the page (page.xml) and the individual grid item (griditem.xml). I have used the following code to inflate the grid items in the gridAdapter code:

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

What I should do to have the height of the RelativeLayout follow the full length of the gridView?

Here is the screenshot: http://tinypic.com/r/98rs4n/4

Android :: Android RelativeLayout - Trying To Vertically Center A TextView When The TextView Below Has No Text

Jul 14, 2010

I have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.
