当重复脉冲按钮移动我在应用程序中时，总是会出现这种内存错误。

我已经检查过它是否在同一个按钮上被多次单击，我还设置了一个条件，即不加载另一个意图来打开另一个活动，直到你不使电流过载。但这不是这个原因。

在我的许多活动中加载许多在滚动视图中膨胀的视图。

对于空闲内存，我试过这个：

在更改活动之前，我执行此视图是一个 android:id 每个活动中使用的布局。

1.-

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();
}

2.-

System.gc();

但这似乎还不够。这是我的LogCat：

在我的应用程序中，每个布局都有他的背景。给我错误的行总是“setContentView（R.layout.xxx）”，所以我减少了所有用作背景的图像，我已经解决了我的内存问题。
