关于安卓bitmap问题，困扰了好久

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。求解答开发-关于安卓bitmap问题，困扰了好久-安卓开发bitmap">

解决方案

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();
}

解决方案二：

要么getlayoutbitmap有问题，要么你的getview有问题
