如何锁定片段的屏幕方向为在运行时横向

我有一个活动的ist片段设置为普通potrait方向，但加载第二个片段时，我需要锁定第二个片段的方向为横向。有可能这样做吗？如何锁定片段的屏幕方向为在运行时横向

这是我的Java片段类

public class DeputationsFragment extends Fragment implements AdapterView.OnItemSelectedListener{

我已经实现相同的功能自己。除了一个片段以外，我的应用程序被锁定为肖像模式。为了实现正确的功能，我使用android:screenOrientation="nosensor"作为活动（在Manifest文件中），防止由于用户旋转设备而导致方向改变。

我还使用android:configChanges="keyboardHidden|orientation|screenSize"来防止活动在方向更改时重新启动。否则，很容易在活动重新开始的循环中结束，进入正确的片段并再次改变方向，重复。

在该片段中的onResume()方法我称之为getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);和它的onPause()我打电话getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

希望这可以帮助你！

试试这个在您的onCreate设置Landscape编程您activities or fragments。

活动

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);

片段

rootView后在Java中加入这一行

getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

定位属性是每个活动，这样你可以宣布定向为只包含片段的活动，以便它处于横向和横向位置其余的活动将保持原样。

所以你需要设置方位onCreateView每个片段的 PLSE检查下面的代码：

FragmentA

public class FragmentA extends Fragment { 


     @Override 

     public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) { 

      View view = inflater.inflate(R.layout.fragment_a, container, false); 
      changeFragmentOrientation(); 


      return view; 

     } 

    } 

public void changeFragmentOrientation(){ 
getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
}

FragmentB

public class FragmentB extends Fragment { 


      @Override 

      public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) { 

       View view = inflater.inflate(R.layout.fragment_b, container, false); 
       changeFragmentOrientation(); 


       return view; 

      } 

     } 

    public void changeFragmentOrientation(){ 
    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
    }

覆盖功能setUserVisibleHint（）在第二个片段，然后用以下代码

@Override 
public void setUserVisibleHint(boolean isVisibleToUser) { 
    super.setUserVisibleHint(isVisibleToUser); 
    if(isVisibleToUser) { 
     Activity curActivity = getActivity(); 
     if(curActivity != null){ 
      curActivity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
     } 
    } 
}

这将是最好的选择。

@Override 
public void setUserVisibleHint(boolean isVisibleToUser) { 
super.setUserVisibleHint(isVisibleToUser); 
if(isVisibleToUser) { 
    Activity a = getActivity(); 
    if(a != null)  a.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
} 
}

好运与乌尔项目:)

这是一个'Fragment'，你不需要声明'Fragments 'on AndroidManifest.xml'然后...答案是不正确的。 – Aspicas
