Question

我有一个Android页面，其中包含3个图像背景和编辑文本和按钮，以及清单文件，其活动如下：

<activity
     Android:name="SearchScreen"
     >
</activity>

我有两个用于potrait的XML，另一个用于横向。当方向发生变化时，对于第一次更改没有问题，但是当它经常更改时应用程序崩溃并且错误看起来像这样

> Android.view.InflateException on orientation change

并且还会使某些VM内存超出范围。

，错误日志如下左图

这个错误只发生在sony erricson Xperia上

Answer 1

在清单中添加您的活动以下代码

<activity android:name="SearchScreen"
android:configChanges="orientation|keyboardHidden"
android:screenOrientation="portrait" android:windowSoftInputMode="stateAlwaysHidden">
</activity>

您也可以使用异步任务来实现这一目标。

Answer 2

如果您的布局中有大量位图，请尝试在activity的onDestory方法中为它们调用recycle？

@Override 
public void onDestroy(){
    ImageView imageViewWithHeavyBitmap = (ImageView)findViewById(R.id.imageview);
    imageViewWithHeavyBitmap.getDrawable().getBitmap().recycle();
}

Android应用程序因方向更改而崩溃
