import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;

public class MyListView extends ListView {

public MyListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyListView(Context context) {
super(context);
}
public  MyListView  (Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);

}

@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);

}

}
