Android WebView:处理方向更改 [英] Android WebView: handling orientation changes

问题描述

问题是轮换后的性能. WebView必须重新加载页面，这可能有点乏味.

The issue is the performance following rotation. The WebView has to reload the page, which can be a bit tedious.

在不每次都从源头重新加载页面的情况下，处理方向变化的最佳方法是什么?

What's the best way of handling an orientation change without reloading the page from source each time?

推荐答案

如果您不希望WebView在方向更改时重新加载，只需在Activity类中重写onConfigurationChanged即可:

If you do not want the WebView to reload on orientation changes simply override onConfigurationChanged in your Activity class:

@Override
public void onConfigurationChanged(Configuration newConfig){        
    super.onConfigurationChanged(newConfig);
}

并在清单中设置android:configChanges属性:

And set the android:configChanges attribute in the manifest:

<activity android:name="..."
          android:label="@string/appName"
          android:configChanges="orientation|screenSize"
