android - gridview 适配器上的 overridePendingTransition

Question

如何在 GridView `Adapter 上插入 overridePendingTransition？这种方式行不通，没有transition startactivity完美运行

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) , 和评论相关，但我不知道如何在 Adapter 中传递 Activity。有帮助吗？

Answer 1

Context 是 Activity 的基础对象(参见:What is the difference between Activity and Context?)，所以我使用了以下内容:

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