android - 如何在 android 2.3.3 中使用 onConfigurationChanged() 和 newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE

Question

我正在使用 onConfigurationChanged()。其中，当我从 LandScape 更改为 Portrait 时，它正在调用 if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) 并从 LandScape 转换为 Portrait。但是当我从 Portrait 更改为 Land-Scape 时，它​​不会更改为 LandScape，因为它正在调用 if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) 所以，它不会从 LandScape 更改为 Portrait .请帮忙。

public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);

        //int orientation = this.getResources().getConfiguration().orientation;

        if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
            Log.d("Entered to change as Portrait ","PPPPPPPPPPPPPPPPP");
            setContentView(R.layout.settings);
        } else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
            Log.d("Entered to change as LandScape ","LLLLLLLLLLLLLLLLLLLL");
            setContentView(R.layout.settings);
        }

    }

只需将以下代码写入onConfigurationChanged方法并测试

if(newConfig.orientation==Configuration.ORIENTATION_LANDSCAPE){

    Log.e("On Config Change","LANDSCAPE");
}else{

    Log.e("On Config Change","PORTRAIT");
}

并像这样将 android:configChanges="keyboardHidden|orientation" 写入您的 list 文件中

<activity android:name="TestActivity"
           android:configChanges="keyboardHidden|orientation">

它在我身边工作，我希望它可以帮助你。

如果您使用的是平板电脑，请将 |screenSize 添加到 android:configChanges
