package com.hysmarthotel.view;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.GridView;
public class MyGridView extends GridView { 
public MyGridView(Context context, AttributeSet attrs) { 
super(context, attrs); 
} 
public MyGridView(Context context) { 
super(context); 
} 
public MyGridView(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); 
} 
}
