setOnTouchListener acharenginebarchart

Question

我想能夠點擊一個圖形來訪問另一個佈局，我不能。我使用一個代碼，直到我進入下面是好的：

mChartView.setOnTouchListener(new OnTouchListener(){ 
      public boolean onTouch(View v, MotionEvent event) { 

       pointx = (int)event.getX(); 
       pointy = (int)event.getY(); 


       Toast.makeText(MainActivity.this, "x="+Integer.toString(pointx)+"y="+Integer.toString(pointy), Toast.LENGTH_SHORT).show(); 
       return false; 
      }}); 

一旦這給了我一個大錯誤，不會讓我運行程序。請一些專家幫助我的圖表。提前 問候也是我離開的所有代碼

我建議你看一看this例如學習如何處理圖表聽衆。

也看看this文章學習一些關於AChartEngine額外的東西。
