单击按钮时，我只需加载一个视图翻转器 xml。此 xml 在所有设备上运行良好，但在 Google Nexus One 设备上报告崩溃。有时它运行时不会崩溃。下面是我的 XML：

利用

android:layout_below="@+id/prev

始终使用“@+id/yourId”

从 Stack Overflow 的一篇文章中得到了我的 OutOfMemoryException 的解决方案。是的，我已将该解决方案标记为向上箭头。

@Override
    protected void onDestroy() {
    super.onDestroy();

    unbindDrawables(findViewById(R.id.RootView));
    System.gc();
    }

    private void unbindDrawables(View view) {
        if (view.getBackground() != null) {
        view.getBackground().setCallback(null);
        }
        if (view instanceof ViewGroup) {
            for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
            unbindDrawables(((ViewGroup) view).getChildAt(i));
            }
        ((ViewGroup) view).removeAllViews();
        }
    }

在 Activity 的 onDestroy() 方法上，调用 unbindDrawables() 方法传递对父视图的引用，然后执行 System.gc()。

这个 unbindDrawables() 方法递归地探索视图树并且：

删除所有背景可绘制对象上的回调删除每个视图组上的子项
