如何運行的浮動泡沫作爲後臺服務，把所有的氣泡代碼OnStart方法內

Question

這在背景Service.java代碼含有onStart()方法 -

@Override 
public void onStart(Intent intent, int startid) { 
    //Toast.makeText(this, "Service started by user.", Toast.LENGTH_LONG).show(); 

    private void addNewBubble() // Error here , says missing token ';' and Expression Expected 

    { 
     windowManager = (WindowManager) getSystemService(WINDOW_SERVICE); 
     //here is all the science of params 
     final WindowManager.LayoutParams myParams = new WindowManager.LayoutParams(
       WindowManager.LayoutParams.WRAP_CONTENT, 
       WindowManager.LayoutParams.WRAP_CONTENT, 
       WindowManager.LayoutParams.TYPE_SYSTEM_ERROR, 
       WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED 
         | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON 
         | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, 
       PixelFormat.TRANSLUCENT 
     ); 
     BubbleLayout bubbleView = (BubbleLayout) LayoutInflater.from(BackgroundService.this).inflate(R.layout.bubble_layout, null); 
     bubbleView.setLayoutParams(myParams); 

     bubbleView.setOnBubbleRemoveListener(new BubbleLayout.OnBubbleRemoveListener() { 
      @Override 
      public void onBubbleRemoved(BubbleLayout bubble) { 
      } 
     }); 
     bubbleView.setOnBubbleClickListener(new BubbleLayout.OnBubbleClickListener() { 

      @Override 
      public void onBubbleClick(BubbleLayout bubble) { 


       Bitmap b = Screenshot.takescreenshotOfRootView(imageView); 
       imageView.setImageBitmap(b); 
       main.setBackgroundColor(Color.parseColor("#999999")); 

       //Toast.makeText(getApplicationContext(), "Clicked !", 
       // Toast.LENGTH_SHORT).show(); 
      } 
     }); 
     bubbleView.setShouldStickToWall(true); 
     bubblesManager.addBubble(bubbleView, 60, 20); 
    } 
} 

private void initializeBubblesManager() { 
    bubblesManager = new BubblesManager.Builder(this) 
      .setTrashLayout(R.layout.bubble_trash_layout) 
      .setInitializationCallback(new OnInitializedCallback() { 
       @Override 
       public void onInitialized() { 
        addNewBubble(); // Cannot resolve this method 
       } 
      }) 
      .build(); 
    bubblesManager.initialize(); 
} 

在MainActivity只包含權限代碼使用checkDrawOverlay（）方法，使用 startService（new Intent（this，BackgroundService.class））運行浮動氣泡; 在其他部分....

您有一個無效的代碼格式這就是爲什麼你的IDE抱怨缺少分號（;）。與句子;

「採取在其中該方法開始和結束仔細看」

我的意思是你需要注意的地方，你聲明的方法，因爲它們可能只在範圍聲明類聲明。目前您正在另一個方法的範圍內聲明一個方法（無效）。例如

public void methodOne() 
{ 
    // this nested method declaration is considerd invalid 
    private void methodTwo() 
    { 
     // method content 
    } 
} 

修復它簡單地做

public void methodOne() 
{ 
    // call other method if you need it to be executed here 
    methodTwo(); 
} 

private void methodTwo() 
{ 
    // method content 
} 

這會照顧missing semicolon error和cannot resolve method error兩者。
