这是我的清单文件的一部分。我已指定禁用横向模式，但在旋转屏幕时仍然会更改方向。我错过了什么？我必须在这里添加任何权限吗？

Answer 1

你可以覆盖每个活动的onConfigurationChanged方法来自己处理方向更改。另外在清单文件中声明android：configChanges你根本无法处理它们。

@Override 
public void onConfigurationChanged(Configuration newConfig) {
   super.onConfigurationChanged(newConfig);
   setRequestedOrientation(ActivityInfo."orientation type your preffer");
}

Answer 2

在android:screenOrientation="portrait" or "landscape"文件中设置manifest时，如果您想要执行此操作，则不会触发侦听器尝试以编程方式处理您的onConfigurationChanged()中的仅限肖像模式，此处您也将是能够再次开始活动。

结帐Documentation on OrientationListener。

即使在禁用活动后，活动的方向仍在变化
