gridview适配器上的overridePendingTransition

Question

如何在GridView适配器上插入overridePendingTransition？这样不工作，没有过渡st​​artactivity工作完美

bt.setOnLongClickListener(new OnLongClickListener(){ 
       @Override 
       public boolean onLongClick(View v) { 
         final String selectedPad = Drum.pads[position]; 
         Intent modPad = new Intent(v.getContext(), ModifyPad.class); 
         modPad.putExtra("pad", selectedPad); 
         context.startActivity(modPad); 
         overridePendingTransition(R.anim.exit_slid_in, R.anim.exit_slid_out); 
        return false; 
       } 
      }); 

我读过这篇文章： android start Activity in adapter (transition animiation direction problem)，以及相关评论，但我不知道如何在Adapter通过Activity。任何帮助？

Answer 1

上下文是活动的基本对象（见：What is the difference between Activity and Context?） 所以就用以下：

Activity activity = (Activity) mContext; 
activity.startActivity(repinIntent); 
activity.overridePendingTransition(R.anim.act_start_in_from_right, R.anim.act_start_out_to_left);
