在onActivityResult中處理返回的資料。
同時一定要在開啟相簿的邏輯中做判斷
Intent intent = new Intent();
intent.setType("image/*");// 從所有圖片中進行選擇
//根據版本號不同使用不同的Action
if (Build.VERSION.SDK_INT <19) {
intent.setAction(Intent.ACTION_GET_CONTENT);
}else {
intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
}
((Activity) context).startActivityForResult(intent, Constants.REQUEST_CODE_HEADPIC_PICK_PHOTO);- 1
