是否有修改android 全景客户端上的内容视图的选项？

例如，我想在顶部显示操作栏。但目前操作栏只是在开始时显示，随后被加载的全景客户端隐藏，因为全景客户端始终以全屏模式显示，尽管它是在一个额外的片段中启动的。

我现在尝试通过一个片段将全景客户端放在一个单独的框架中 - 这是我到目前为止的代码：


1. 这是全景片段和文本字段的活动：

public class PanoramaActivity extends Activity {

public static final String TAG = PanoramaActivity.class.getSimpleName();

private ActionBar actionBar;
private Fragment panoramaClient = new PanoramaClientFragment();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_snow);
    actionBar = getActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);


    FragmentManager fragMan = getFragmentManager();
    FragmentTransaction fragTrans = fragMan.beginTransaction();

    fragTrans.replace(R.id.panoramaCLientFrame, panoramaClient, "PANO");
    fragTrans.commit();

  //Non fullscreen
    requestWindowFeature(Window.FEATURE_ACTION_BAR);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.panorama, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case android.R.id.home: 
        onBackPressed();
        break;

    default:
        return super.onOptionsItemSelected(item);
    }
    return true;
}
}


2.这是带有全景客户端的片段类：

public class PanoramaClientFragment extends Fragment implements ConnectionCallbacks,
OnConnectionFailedListener, OnPanoramaInfoLoadedListener {

private View view;
private PanoramaClient panoramaClient;

public static final String TAG = PanoramaClientFragment.class.getSimpleName();

public PanoramaClientFragment() {
    // TODO Auto-generated constructor stub
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle     savedInstanteState){
    view = inflater.inflate(R.layout.panorama_client, container, false);
    return view;
}

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    panoramaClient = new PanoramaClient(getActivity().getApplicationContext(), this, this);

//Non fullscreen
//getActivity().requestWindowFeature(Window.FEATURE_ACTION_BAR);
//getActivity().getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
//getActivity().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

@Override
public void onStart() {
    super.onStart();
    panoramaClient.connect();
}

@Override
public void onPanoramaInfoLoaded(ConnectionResult result, Intent viewerIntent) {
    if (result.isSuccess()) {
        Log.i(TAG, "found viewerIntent: " + viewerIntent);
        if (viewerIntent != null) {
            startActivity(viewerIntent);
        }
    } else {
        Log.e(TAG, "error: " + result);
    }
}

@Override
public void onConnectionFailed(ConnectionResult status) {
    Log.e(TAG, "connection failed: " + status);
}

@Override
public void onConnected(Bundle arg0) {
    Uri uri = Uri.parse("android.resource://" + this.getActivity().getPackageName() + "/" + R.raw.pano1);
    panoramaClient.loadPanoramaInfo(this, uri); 
}

@Override
public void onDisconnected() {
    // Do nothing.
}

@Override
public void onStop() {
    super.onStop();
    panoramaClient.disconnect();
}
}

如果我取消注释片段类中的三个“非全屏”行，应用程序崩溃并说：

android.util.AndroidRuntimeException: requestFeature() 必须在添加内容之前调用


感谢您的回复。问候。

我认为您无法显示操作栏有一个简单的原因，当您加载全景信息时，您正在开始一项完全不受您控制的新活动。

if (viewerIntent != null) {
    startActivity(viewerIntent);
}

因此，您的代码尝试修改处理 PanoramaClient 实例的活动，而不是加载全景图像的活动。

尝试创建一个片段并将全景客户端活动添加到其中。
