In the Android example, ApiDemos, there is a activity: Focus2,

code:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

package com.google.android.samples.view;
 
import com.google.android.samples.R;
 
import android.app.Activity;
 
import android.os.Bundle;
 
public class Focus2 extends Activity {
 
    protected void onCreate(Bundle savedInstanceState) {
 
        super.onCreate(savedInstanceState);
 
        setContentView(R.layout.focus_2);
 
    }
 
}

        android:layout_marginRight="3dip"
 
        android:text="@string/focus_2_jump" />
 
    <Button android:id="@+id/rightButton"
 
        android:layout_width="wrap_content"

when first enter this activity, and press any key, then the first button is focused.
My questions is: how to change the code, let the second button to be focused when I first press any navigate key. I try requestFocus(), but failed.

Hello flydream,

lets say, requestFocus() should be working. (Did you als try to write [font=Lucida Console]<requestFocus/>[/font] to xml ?)

Focus-stuff seems to be currently a bit buggy: http://www.anddev.org/viewtopic.php?t=1110

Yes. I have tried these two method to set the default focus.
one is set attribute in xml:
<Button android:id="@+id/centerButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="3dip"
android:text="@string/focus_2_jump"
android:focusableInTouchMode="true">
<requestFocus/>
</Button>

the other is in code:
setContentView(R.layout.focus_2);
findViewById(R.id.centerButton).requestFocus();

But these two method have no effects on the default focus.

Hello flydream

I could swear this was working in m3... lets hope it shows correct behavior in the next sdk-releases.
