的Android全屏幕不能正常工作時，活動由服務

Question

所以我正在開發一個替代lockscreenapp 推出，我需要防止點擊notificationbar

所以我儘量在fullscreenn

但是，當運行這個程序它是大道由notificationbar仍然是他們當它被髮射稱之爲得到無形 代碼服務： 公共類的應用程序擴展活動{

TextView datum; 
static TextView time; 

static TextView temperature; 
static ImageView weather_icon; 
static TextView weather_refreshed; 
static RelativeLayout refresh; 

private static Context mContext; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 

    setContentView(R.layout.main); 



    this.startService(new Intent(this, lockservice.class)); 


    mContext = this; 


    //Date 
    datum = (TextView) findViewById(R.id.datum); 
    SimpleDateFormat sdf = new SimpleDateFormat("E dd MMM"); 
    String currentDateandTime = sdf.format(new Date()); 
    datum.setText(currentDateandTime); 

    //Time 
    time = (TextView) findViewById(R.id.clock); 
    Date date = new Date(); 
    int hours = date.getHours(); 
    String diplay_hours = String.valueOf(hours); 
    int minutes = date.getMinutes(); 
    String diplay_minutes = String.valueOf(minutes); 
    if(hours < 10) 
    { 
     diplay_hours = "0"+String.valueOf(hours); 
    } 
    if(minutes < 10) 
    { 
     diplay_minutes = "0"+String.valueOf(minutes); 
    } 
    time.setText(String.valueOf(diplay_hours+":"+diplay_minutes)); 


    //update 
    Thread myThread = new Thread(new UpdateThread()); 
    myThread.start(); 

    // Weather 
    temperature = (TextView) findViewById(R.id.weather_temp); 
    weather_icon = (ImageView) findViewById(R.id.weather_icon); 
    weather_refreshed = (TextView) findViewById(R.id.weather_refreshed); 



    refresh = (RelativeLayout) findViewById(R.id.relativeLayout1); 
    refresh.setOnClickListener(new OnClickListener() { 
      @Override 
      public void onClick(View v) { 
      weather.download(); 

     } 
     }); 
} 
@Override 
public void onResume() { 
    super.onResume(); 


} 



@Override 
public void onAttachedToWindow() 
{ 
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD); 




    super.onAttachedToWindow(); 

} 
@Override 
public boolean onKeyDown(int iKeyCode, KeyEvent event) 
{ 

    if(iKeyCode == KeyEvent.KEYCODE_BACK || iKeyCode == KeyEvent.KEYCODE_HOME) 
    { 
     finish(); 
     return true; 
    } 
    return false; 
    } 


//update 
public Handler updateHandler = new Handler(){ 
    /** Gets called on every message that is received */ 
    // @Override 
    public void handleMessage(Message msg) { 

     //Time 
    time = (TextView) findViewById(R.id.clock); 
    Date date = new Date(); 
    int hours = date.getHours(); 
    String diplay_hours = String.valueOf(hours); 
    int minutes = date.getMinutes(); 
    String diplay_minutes = String.valueOf(minutes); 
    if(hours < 10) 
    { 
     diplay_hours = "0"+String.valueOf(hours); 
    } 
    if(minutes < 10) 
    { 
     diplay_minutes = "0"+String.valueOf(minutes); 
    } 
    time.setText(String.valueOf(diplay_hours+":"+diplay_minutes)); 


    //weather 
    weather.display(); 
    try 
    { 
     SharedPreferences weather = app.getContext().getSharedPreferences("weather",app.getContext().MODE_WORLD_READABLE); 
    app.weather_refreshed.setText(weather.getString("time","")); 
    } 
    catch(Exception x) 
    { 

    } 
    super.handleMessage(msg); 
    } 
}; 


public class UpdateThread implements Runnable { 



    @Override 
    public void run() { 
     while(true){ 

      long startTime = System.currentTimeMillis(); 
      app.this.updateHandler.sendEmptyMessage(0); //handler 

      Thread.yield();     
      try { 
       Thread.sleep(1000); 
      } catch (InterruptedException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 

     } 

    } 

} 

public static Context getContext(){ 
    return mContext; 
} 

@Override 
    public void onPause() { 

     super.onPause(); 

    } 

我也用鍵盤鎖 全屏在我的清單中實現：

<application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" > 
     <activity 
      android:name=".app" 
      android:label="@string/app_name" 
      android:screenOrientation="portrait" 
      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> 
     <receiver android:name="boot"> 
      <intent-filter> 
       <action android:name="android.intent.action.BOOT_COMPLETED"/> 
       <category android:name="android.intent.category.HOME" /> 
      </intent-filter> 
     </receiver> 

     <service 
     android:name="lockservice" 
     android:process=":lockscreen" 
     android:icon="@drawable/ic_launcher" 
     android:label="Lockscreen"> 
     </service> 

     <activity 
      android:name=".weather_update" 
      android:theme="@android:style/Theme.Translucent"> 

     </activity> 

    </application> 

Answer 1

我用全屏幕前一樣用自己的方式，並出現了一些問題，但沒有嘗試推出從服務活動，嘗試應用全屏這樣一來，

WindowManager.LayoutParams attrs = getWindow().getAttributes(); 
attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN; 
getWindow().setAttributes(attrs); 

以防萬一，你需要退出全屏，你能做到這樣，

WindowManager.LayoutParams attrs = getWindow().getAttributes(); 
attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN); 
getWindow().setAttributes(attrs); 

給它一個鏡頭，祝你好運！

Answer 2

看來this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);會導致此問題。

其他人建議延遲該呼叫：請參閱Activity doesn't show in full screen。
