Android動態視圖上的氣泡

Question

任何人都可以在Android佈局上製作可點擊的動態氣泡。

我的設計師認爲屏幕下面是[！[我圖像所有的泡泡都是分配給用戶的一些任務集。泡泡的標籤根據任務改變] [1]] [1]

根據我的項目要求，顏色和半徑會根據api響應而改變。

可以請您提供任何演示或示例。我GOOGLE了，但我無法找到答案。請指導我完成此操作。

作爲一個答案已經發布，我也嘗試過你。希望你也能從這裏得到一些幫助：

public class BubbleBackgroundDemoActivity extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     View view = new CustomView(this); 
//  RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(this.getWidth(), 
//    ViewGroup.LayoutParams.MATCH_PARENT); 
//  view.setLayoutParams(lp); 


     setContentView(view); 
    } 

    public class CustomView extends View { 

     private Paint paint; 
     int screenWidth, screenHeight; 



     public CustomView(Context context) { 
      super(context); 
      DisplayMetrics displaymetrics = new DisplayMetrics(); 

      getWindowManager().getDefaultDisplay().getMetrics(displaymetrics); 


      screenWidth = displaymetrics.widthPixels; 
      screenHeight = displaymetrics.heightPixels; 

      // create the Paint and set its color 
      paint = new Paint(); 
      paint.setColor(Color.GRAY); 

     } 

     @Override 
     protected void onDraw(Canvas canvas) { 
      canvas.drawColor(Color.BLUE); 
      canvas.drawCircle(200, 200, 100, paint); 


      canvas.drawCircle(screenWidth-200, 200, 100, paint); 

      canvas.drawCircle(screenWidth/2, screenHeight/2, 300, paint); 

      canvas.drawCircle(screenWidth-200, screenHeight-200, 100, paint); 

      canvas.drawCircle(200, screenHeight-200, 100, paint); 

     } 

    } 

}

這是你如何自定義創建圈各種參考，鏈接，在畫布上創建圈子動態

public class CustomView extends View { 

    private Paint paint; 

    public CustomView(Context context) { 
     super(context); 

     // create the Paint and set its color   
     paint = new Paint(); 
     paint.setColor(Color.GRAY); 
    } 

    @Override 
    protected void onDraw(Canvas canvas) { 
     canvas.drawColor(Color.BLUE); 
     canvas.drawCircle(200, 200, 100, paint); 
    } 

} 

public class MainActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(new CustomView(this)); 
    } 

}
