Android无法检测屏幕旋转

Question

我在检测屏幕旋转时遇到问题。我什至尝试添加 android:configChanges="orientation|keyboardHidden"。

欢迎任何帮助。

这是我的支票代码:

public void onConfigurationChanged(Configuration newConfig) {
  super.onConfigurationChanged(newConfig);
  if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
     Log.v("o", "oo");
  } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
     Toast.makeText(this, "portrait", Toast.LENGTH_LONG).show();
  }
}

Caution: Beginning with Android 3.2 (API level 13), the "screen size"also changes when the device switches between portrait and landscapeorientation. Thus, if you want to prevent runtime restarts due toorientation change when developing for API level 13 or higher (asdeclared by the minSdkVersion and targetSdkVersion attributes), youmust include the "screenSize" value in addition to the "orientation"value. That is, you must decalareandroid:configChanges="orientation|screenSize"
