How can I get Width and Height of RelativeLayout - android-layout

Question

I am not able to get width and height of RelativeLayout, how can I get this? My layout.xml file is
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/layoutMain"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="50dp" >
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerInParent="true"
android:layout_gravity="center_horizontal"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
and I just get programtically height and width of RelativeLayout using its built-in provided method like,
public class CustomShowcaseActivity extends Activity { static float width;
static float height; RelativeLayout relMain;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom_showcase);
relMain= (RelativeLayout) findViewById(R.id.layoutMain);
width = relMain.getMeasuredWidth();
height = relMain.getMeasuredHeight();
width = relMain.getWidth();
height = relMain.getHeight();
System.out.println("=== Width : " + width);
System.out.println("=== height : " + height);
} }
Can anyone help me with this issue?

Answer 1

override this method first.
#Override
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
super.onWindowFocusChanged(hasFocus);
getRelativeLayoutInfo();
}
Try by using only getHeight() and getWidth()
private void getRelativeLayoutInfo(){
relMain = (RelativeLayout) findViewById(R.id.layoutMain);
w = relMain.getWidth();
h = relMain.getHeight();
Log.v("W-H", w+"-"+h);
}
