android - 如何禁用主要活动的方向更改？

Question

我有一个这样的滚动视图的相对布局：

<RelativeLayout
 android:layout_width="fill_parent"
 android:layout_height="576dp"
 android:background="@drawable/text_main" 
 >

我想停止方向更改并使其垂直固定。我怎样才能做到这一点？

Answer 1

将此添加到AndroidManifest.xml的MainActivity中：

<activity
...
android:screenOrientation="landscape"
... >
</activity>

Answer 2

There are two ways of doing this

1. Static

       <activity
           android:name="com.photon.filnobep.activities.ActivitySettings"
           android:icon="@drawable/icon_small"
           android:label="@string/title_activity_activity_settings"
           android:logo="@drawable/icon_small"
           android:screenOrientation="landscape"
           android:theme="@style/MyTheme" >
       </activity>
   

2. Pro-grammatically(In your java class)

   setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Note: using Static method you still can change Orientation from you java Class

Answer 3

根据你的

 <activity>

您可以在清单中添加标签

android:screenOrientation="portrait"
android:configChanges="keyboard|keyboardHidden|orientation" >
