ImageButton +對話框問題

Question

嘿，我正在嘗試做一個對話框。但整個對話沒有顯示出來，只有最底層的3個圖像按鈕正在顯示：這裏有什麼問題？而當我點擊對話框內的按鈕時，即使我做了一個開關盒，也沒有任何反應。

customtype_dialog.xml

routeType = (ImageButton)findViewById(R.id.saveRoute_activityType); 
     routeType.setOnClickListener(typeListener); 

SaveRouteActivity.java

這是我的聽衆。

View.OnClickListener typeListener = new OnClickListener() { 
       public void onClick(View v) { 

        switch(v.getId()){ 
        case R.id.saveRoute_activityType: 
         Dialog typedialog = new Dialog(SaveRouteActivity.this); 
         typedialog.setContentView(R.layout.customtype_dialog); 
         typedialog.setTitle("Select type"); 
         typedialog.setCancelable(true); 
         typedialog.show(); 
         break; 

        case R.id.dialog_btn1: 
         txtType.setText("Run"); 
         routeType.setBackgroundResource(R.drawable.track_run); 
         break; 

        case R.id.dialog_btn2: 
         txtType.setText("Bike"); 
         routeType.setBackgroundResource(R.drawable.track_bike); 
         break; 

        case R.id.dialog_btn3: 
         txtType.setText("Walk"); 
         routeType.setBackgroundResource(R.drawable.track_walk); 
         break; 

        case R.id.dialog_btn4: 
         txtType.setText("Ski"); 
         routeType.setBackgroundResource(R.drawable.track_ski); 
         break; 

        case R.id.dialog_btn5: 
         txtType.setText("Boat"); 
         routeType.setBackgroundResource(R.drawable.track_boat); 
         break; 

        case R.id.dialog_btn6: 
         txtType.setText("Snowboarding"); 
         routeType.setBackgroundResource(R.drawable.track_snow_boarding); 
         break; 
        } 

       } 
      };

我的猜測是typedialog.setContentView(R.layout.customtype_dialog);被忽略，因爲該對話框還沒有被充值。要解決該問題，您應該創建Dialog的子類，並在其onCreate()方法中調用setContentView()。
