如何在反应原生android中锁定景观方向？

Question

I'm creating an Android app using react-native. I need to create the app for the Nexus 9 tab in Landscape mode. I already created the Nexus 9 tab emulator in Android studio with Android 10.0 x86 API level 29. The problem is, App is still locked to portrait mode.

To make the view in Landscape mode, I added android:screenOrientation="landscape" to the <activity> in AndroidManifest.xml as follows

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.sipandroid">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:allowBackup="false"
      android:theme="@style/AppTheme">
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:screenOrientation="landscape"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
      </activity>
      <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
    </application>

</manifest>

Even after I modified to the above code, App is still locked to the portrait mode . How can I take this to the landscape mode?

Answer 1

简单地在您创建的特定活动的主体中使用此标签 android:orientation="vertical <activity android:name="com.facebook.react.devsupport.DevSettingsActivity" android:screenOrientation="fullSensor" />

Answer 2

I fixed it. The problem was the Android version and the API level . I changed it from 10.0 API level 29 to 9.0 API level 28 and now it's working
