关于安卓bitmap问题，困扰了好久

Question

代码如图，我想用gallery显示bitmap出来，可是显示的图片都是一样的，为什么呢，如果说是bitmap内存没释放，我用recyle方法时候程序会闪退。求解答

Answer 1

public void GetBMP(){

    LinearLayout contentLayout;
    contentLayout = (LinearLayout) findViewById(R.id.test); 
    contentLayout.setDrawingCacheEnabled(true);     
    contentLayout.measure(     
        MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),     
        MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));     
    contentLayout.layout(0, 0, contentLayout.getMeasuredWidth(),     
                         contentLayout.getMeasuredHeight());     
    contentLayout.buildDrawingCache();     
    bitmap= contentLayout.getDrawingCache();  
}
