來電屏幕上的浮動窗口

Question

我想在有人打電話給我時顯示一些信息。 我有服務。此服務已註冊廣播接收方。此接收器偵聽android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED。 我可以在我的手機解鎖時顯示烤麪包，但是當我鎖定手機並有人向我打電話時，烤麪包沒有顯示。 有人打電話給我時，顯示某些信息的最佳方式是什麼？

更新： 我創建了浮動窗口，當手機響起時我會打開。 這項工作非常好，但當電話被鎖定並且某人正在打電話給我時，窗口不顯示。當我接聽電話時，浮動窗口就在那裏。這裏有一些方法可以顯示鎖屏來電屏幕上的這個啓動窗口嗎？ 這是我打開浮動窗口的方式：

new Handler().postDelayed(new Runnable() { 

       @Override 
       public void run() { 
        startService(new Intent(context, FloatingWindow.class)); 
       } 
      }, 2000); 

，這是我的蓮花窗口

public class FloatingWindow extends Service{ 

private WindowManager wm; 
private LinearLayout ll; 
private Button btnStop; 

@Nullable 
@Override 
public IBinder onBind(Intent intent) { 
    return null; 
} 

@Override 
public void onCreate() { 
    super.onCreate(); 

    wm = (WindowManager) getSystemService(WINDOW_SERVICE); 
    ll = new LinearLayout(this); 
    btnStop = new Button(this); 

    ViewGroup.LayoutParams btnParameters = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
    btnStop.setText("Stop"); 
    btnStop.setLayoutParams(btnParameters); 

    LinearLayout.LayoutParams llParameters = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT); 
    ll.setBackgroundColor(Color.argb(66, 255, 0, 0)); 
    ll.setLayoutParams(llParameters); 

    final WindowManager.LayoutParams parameters = new WindowManager.LayoutParams(400, 150, WindowManager.LayoutParams.TYPE_PHONE, WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, PixelFormat.TRANSLUCENT); 
    parameters.x = 0; 
    parameters.y = 0; 
    parameters.gravity = Gravity.CENTER | Gravity.CENTER; 

    ll.addView(btnStop); 
    wm.addView(ll, parameters); 

    ll.setOnTouchListener(new View.OnTouchListener() { 

     private WindowManager.LayoutParams updatedParameters = parameters; 
     int x, y; 
     float touchedX, touchedY; 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      switch (event.getAction()) { 
       case MotionEvent.ACTION_DOWN: 
        x = updatedParameters.x; 
        y = updatedParameters.y; 

        touchedX = event.getRawX(); 
        touchedY = event.getRawY(); 
        break; 
       case MotionEvent.ACTION_MOVE: 
        updatedParameters.x = (int) (x + (event.getRawX() - touchedX)); 
        updatedParameters.y = (int) (y + (event.getRawY() - touchedY)); 

        wm.updateViewLayout(ll, updatedParameters); 
        break; 
       default: 
        break; 
      } 
      return false; 
     } 
    }); 

    btnStop.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      wm.removeView(ll); 
      stopSelf(); 
     } 
    }); 
} 

}

好了，我一年前解決了這個問題，但沒有人但寫了這個問題，所以我會給我的解決方案。

這是我如何打開浮動窗口：

new Handler().postDelayed(new Runnable() { 
    @Override 
    public void run() { 
     context.startService(new Intent(context, FloatingWindow.class)); 
    } 
}, 1000); 

在這裏，從的onCreate我FloatingWindow服務

@Override 
public void onCreate() { 
    super.onCreate(); 

    wm = (WindowManager) getSystemService(WINDOW_SERVICE); 
    ll = new LinearLayout(this); 
    btnStop = new Button(this); 

    gestureDetector = new GestureDetector(this, new GestureListener()); 

    ViewGroup.LayoutParams btnParameters = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, 
      ViewGroup.LayoutParams.WRAP_CONTENT); 
    btnStop.setText("X"); 
    btnStop.setLayoutParams(btnParameters); 

    ViewGroup.LayoutParams tvParameters = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 
      ViewGroup.LayoutParams.MATCH_PARENT); 

    LinearLayout.LayoutParams llParameters = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT); 
    ll.setBackgroundColor(Color.argb(255, 255, 0, 0)); 
    ll.setLayoutParams(llParameters); 

    final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
      WindowManager.LayoutParams.MATCH_PARENT, 
      WindowManager.LayoutParams.WRAP_CONTENT, 
      WindowManager.LayoutParams.TYPE_SYSTEM_ERROR, 
      WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, 
      PixelFormat.TRANSLUCENT); 

    params.gravity = Gravity.CENTER; 

    View popup_view = ((LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.popup_window, ll, false); 
    tvInfo = (TextView) popup_view.findViewById(R.id.message); 
    tvInfo.setText(this.getMessage()); 

    ll.addView(popup_view); 
    wm.addView(ll, params); 



    ll.setOnTouchListener(new View.OnTouchListener() { 

     private WindowManager.LayoutParams updatedParameters = params; 
     int x, y; 
     float touchedX, touchedY; 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      gestureDetector.onTouchEvent(event); 
      switch (event.getAction()) { 
       case MotionEvent.ACTION_DOWN: 
        x = updatedParameters.x; 
        y = updatedParameters.y; 

        touchedX = event.getRawX(); 
        touchedY = event.getRawY(); 
        break; 
       case MotionEvent.ACTION_MOVE: 
        updatedParameters.x = (int) (x + (event.getRawX() - touchedX)); 
        updatedParameters.y = (int) (y + (event.getRawY() - touchedY)); 

        wm.updateViewLayout(ll, updatedParameters); 
        break; 
       default: 
        break; 
      } 
      return false; 
     } 
    }); 

    gestureDetector.setOnDoubleTapListener(new GestureDetector.OnDoubleTapListener() { 
     @Override 
     public boolean onSingleTapConfirmed(MotionEvent e) { 
      return true; 
     } 

     @Override 
     public boolean onDoubleTap(MotionEvent e) { 
      stopSelf(); 
      return false; 
     } 

     @Override 
     public boolean onDoubleTapEvent(MotionEvent e) { 
      return true; 
     } 
    });  
} 

它甚至鎖定屏幕上完美運行。
