我想让我的应用程序只在android中的横向

Question

我想让我的应用程序仅在横向模式下工作,但无法使其工作.我已经给出了screenOrientation = "landscape"即使第一页将处于横向模式,其他活动将是纵向的.

XML文件

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".Main"
              android:label="@string/app_name"
              android:screenOrientation="landscape" android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>     

    </activity>

    <activity android:name=".IntroHome"
              android:label="@string/app_name"
              android:screenOrientation="landscape">
    </activity>

    <activity android:name=".ObjectivesPage"
              android:label="@string/app_name"
              android:screenOrientation="landscape" >
    </activity>

    <activity android:name=".MenuPage"
              android:label="@string/app_name"
              android:screenOrientation="landscape" >
    </activity>
</application>

JAVA CLASS

public class ObjectivesPage extends Activity{

    ImageButton  imgButton;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.objectivespage);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        imgButton = (ImageButton)findViewById(R.id.buttonCloseNGo);
        imgButton.setOnClickListener(onClickCloseNGo);
    }

    private OnClickListener onClickCloseNGo = new OnClickListener(){

        public void onClick(View v) {
            Intent intent = new Intent(ObjectivesPage.this,MenuPage.class);
            startActivity(intent);
        }
    };
}

保持清单的这一部分已经存在.例如,考虑IntroHome活动.

<activity android:name=".IntroHome"
           android:label="@string/app_name"
           android:screenOrientation="landscape"  
           >
</activity>

对于活动XML,请确保仅在layout-land文件夹中具有IntroHome活动布局XML .这样,您拥有的活动/活动将仅显示您已定义的XML的横向版本.
