Hii All,
I am developing a game in android and i want to capture screen
coordinates of a view(ImageView) which is embedded in frame.
Hierarchy is
<LinearLayout android android:layout_height="fill_parent"
android:layout_width="fill_parent" >
<RelativeLayout android:layout_height=fill_parent"
android:layout_width="fill_parent" >
<FrameLayout android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="@+id/frame14"></FrameLayout>
</RelativeLayout>
</LinearLayout>
At run time i am attaching two image views for frame layout.I wanted
to capture screen coordinates of frame layout.But Couldnt do it.if i
say
(FrameLayout) f=(FrameLayout)findViewById(R.id.frame14);
int[] loc = new int[2];
f.getLocationOnScreen(loc);
System.out.println(loc[0]);
System.out.println(loc[1]);
I get Null Pointer Exception for getLocationOnScreen() method.
If I try to get f.getLeft() and f.getRight() they return as 0
coordinates.
Can anyone please tell me how to find location on screen of a view.
I tried even in onStart() method,,,still i get Null Pointer Exception.
Please tell me how to get screen coordinates of a view in android.
It is very urgent.Please help.
Thanks
Kavitha
