I have an app with the following code using android 2.0.1
int[] loc = new int[2];
Button btn = (Button) findViewById( R.id.btn3 );
if( btn != null )
btn.getLocationInWindow( loc);
Log.i("Where?","x=" + where[0] + " y=" + where[1] );
This logs "x=0 y=88" but R.id.btn3 is in the middle of the screen!
I was experiencing this in android 2.0.1 so I wrote the following test
app in android 2.1 that logs the XY coordinates of a button in the
middle of the screen.
This logs "x=0 and y=0"
public class TestLoc extends Activity
{
@Override
public void onCreate( Bundle savedInstanceState )
{
super.onCreate( savedInstanceState );
setContentView( R.layout.main );
}
@Override
public void onStart()
{
super.onStart();
int[] where = new int[2];
Button view = (Button) findViewById( R.id.btnThree );
if( view != null )
{
view.getLocationInWindow( where );
Log.i("Where?","x=" + where[0] + " y=" + where[1] );
}
}
}
<?xml version="1.0" encoding="utf-8"?>
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TableRow android:id="@+id/rowOne">
<Button android:id="@+id/btnOne"/>
</TableRow>
<TableRow android:id="@+id/rowTwo">
<Button android:id="@+id/btnTwo"/>
<Button android:id="@+id/btnThree"/>
</TableRow>
</TableLayout>
Wha's up? Is there a reliable way to get the window coordinates of
any view?
Thanks for reading,
Clark
