如何运行的浮动泡沫作为后台服务，把所有的气泡代码OnStart方法内

Question

这在背景Service.java代码含有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只包含权限代码使用checkDrawOverlay（）方法，使用 startService（new Intent（this，BackgroundService.class））运行浮动气泡; 在其他部分....

您有一个无效的代码格式这就是为什么你的IDE抱怨缺少分号（;）。与句子;

“采取在其中该方法开始和结束仔细看”

我的意思是你需要注意的地方，你声明的方法，因为它们可能只在范围声明类声明。目前您正在另一个方法的范围内声明一个方法（无效）。例如

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

修复它简单地做

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

private void methodTwo() 
{ 
    // method content 
} 

这会照顾missing semicolon error和cannot resolve method error两者。
