Android : Change The Height Of A Webview On Runtime
Feb 26, 2010
I have a webview and a table containing 4 buttons. I have set the height of the webview to 400px, so that the buttons are displayed at the bottom of the screen, in portrait mode. My problem is, when changed to landscape mode the buttons are not visible. So I need to change the height of the webview on runtime, when orientation is changed. Do anybody know how to achieve this? I am able to capture the orientation change, using 'onConfigurationChanged' function.

My application generates an HTML file which needs to be displayed to the user . For this purpose I'm using the loadData() API provided by Webview. This HTML file is updated every 2 secs & the same is loaded again using loadData() to display the updated values. On reloading the file the Webview starts displaying again from the top of the file causing the user to always scroll down to the location where he previously was. This causes a very bad user experience. To overcome this issue an alternative that I could think of was to split the file to multiple files that can exactly fit in the the screen. For this I need to find the height of the HTML content that can loaded in a web view. From the WebView documentation I found that an API getContentHeight() is provided for this purpose. Although this method returns me 0 on the first attempt. On subsequent attempt it gives me the height of the page that was previously loaded.

Is there a way that after install a app, user can have the option to change the app name through a configuration page in that app? Where are all app names saved in the system?

I am developing an Android App which communicated with a server. User can select a language of his choice at startup or during the App execution lifetime. After selecting the language, the corresponding XML file is downloaded from server according to language which will map the "Values" of Application strings according to that language. Can I do something like replacing the default Strings.xml which contains English names(Say by default) to the language selected by user. Better will be adding an XML file per language and referring it runtime directly.

Is it possible to have a user choose how an app should respond to orientation changes? I have it set to android:screenOrientation="sensor" in the manifest but I would like users to be able to turn this on and off or set landscape or portrait orientation permanently.

Well, preventing an orientation change is easy. But what about doing it at run time.
Say, I have an activity which supports orientation change in normal situations. It has say three Edit Texts.
There's also a button, which when clicked would do some processing in a thread while showing a ProgressDialog which is not cancellable.
Ok, so till the user hits the Button, I want the activity to be able to adapt the orientation changes. I have two layouts files for each orientation with different layout schemes.
What I want is this. Once the user clicks on the button, and the ProgressDialog is showing, I don't want the activity now to be re- created again when the orientation changes. So, before showing the ProgressDialog, is there any way to tell the Activity not to handle Orientation change?
Also, once the process is complete, and the ProgressDialog is removed, I want the Activity again to be able to handle orientation changes.

For an application I need to place some objects at the exact position that I want to have them and therefore I need to use AbsoluteLayout this time.
I want to add buttons dynamically exactly like in the following XML - but during runtime.

How can I archive this? I tried it with the following code to add a button, but I haven't found a function so far to set layout_x and layout_y. How can I do this?

I want the ability to re-arrange Views in a LinearLayout, without specifying specific pixel locations, at runtime. for my proof of concept, I have a layout with 2 TextViews, one red, and one black. The red TextView is on the left. I want onClick to set it to be on the right, without adjusting margins, as if I'd re-written the XML of the layout, with the red TextView second.

I want when a user clicks a row, that row grows to show more items with an scale animation, but I can't find how can I do that.
First: I don't know how can I change a height row at runtime. I've tried making the items visible, but this didn't work even if I inflate with another XML layout.
Second: If I achieve the first one, I think I could make the scale animation.

I have a card game I created in android and it is possible to show the scores at any given time by clicking a menu option. I would like that scores dialog to show a different background image when it's loaded depending on factors like who's leading, etc. In my constructor, I have the following relevant code:
public ScoresDialog(Context context) {
super(context);
this.setTitle(R.string.scoresDialogHeading);
setContentView(R.layout.scores_view);
...
}
I have tried getting that view to change it in the showDialog method i wrote like so: findViewById(R.layout.scores_view).setBackgroundColor(Color.BLUE); However, I got a NPE... I tried moving this statement to the onStart method, thinking that the view is not yet initialized but got the same error... Any thoughts on what the right way to do something like that is?

Suppose, I have 10 rows and there should be a divider height of 5 between first 2 rows and then there should be a divider height of 1 between next 5 rows and so on.

I've prepared custom component based on LinearLayout. Whole component is defined in XML. Currently to use it you have to write:
<com.xxx.android.components.TopMenu
android:layout_width="fill_parent"
android:layout_height="44dp" />
Is it possible to set width and height in the java constructor? So it would be possible to write just:
<com.xxx.android.components.TopMenu />
I've tried to modify and set LayoutParams, but it didn't work for me.

I have three ListView widgets in the same LinearLayout. Something like this (I'm omitting XML elements that are not relevant in this example):
CODE:..............
This forces the list to have a height of 360 dip. Of course, that will be its height even if there are few list items. So, my question is how can make the lists have an automatic height? What I want is that the ListView height takes the exact size of the sum of all its list items.

Every time that I want to do a Layout, I'm getting a black layout preview then I can drop stuff on it, that's ok, but how can I change the size of that blank surface (xml). The question came because I set a folder layout-large and then when I add a new layout.xml to that folder it came with the same size, as a layout-normal.
