我为清单文件中的活动添加了android:configChanges =“ density”。但是我没有收到onConfigurationChanged()回调

    <?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".ClientActivity" android:configChanges="density">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

我在下面提到了onConfigurationChanged()方法。其实我在那个里面什么也没做。如果我回电,我想继续进行下去。

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

添加清单

android:configChanges="keyboardHidden|orientation|screenSize"

添加活动。

@Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
            Log.d("OrientationMyApp", "Current Orientation : Landscape");

        } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        Log.d("OrientationMyApp", "Current Orientation : Portrait");
        // Your magic here for portrait mode
      }
   }
