Android Intent.createChooser 应用选择器

在常见的Activity Action Intent常量中，ACTION_PICK android.intent.action.PICK 是“选择数据”的意思，来简单的分享一下我知道的Intent.ACTION_PICK的一些用法：

（一）、调用图库，获取所有本地图片：
Intent imageIntent = new Intent(Intent.ACTION_GET_CONTENT);
imageIntent.setType(“image/*”);
startActivityForResult(imageIntent, PICK_CODE); //PICK_CODE是常量

（二）、调用本地联系人：
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
startActivityForResult(intent, PICK_CONTACT);
（三）、调用音乐，获取所有本地音乐文件：
Intent audioIntent = new Intent(Intent.ACTION_GET_CONTENT);
audioIntent.setType(“audio/*”);
startActivityForResult(audioIntent, PICK_AUDIO);
（四）、调用视频，获取所有本地视频文件：
Intent videoIntent = new Intent(Intent.ACTION_GET_CONTENT);
videoIntent.setType(“video/*”);
startActivityForResult(videoIntent, PICK_VIDEO);

例如：

 public static void jumpToChooser(Activity activity) {        if (activity == null) {            return;        }        Intent intent = new Intent(Intent.ACTION_PICK);        intent.setType("image/*");        PackageManager packageManager = activity.getPackageManager();        List<ResolveInfo> resInfo = packageManager.queryIntentActivities(intent, 0);        if (resInfo != null && (!resInfo.isEmpty())) {            List<Intent> targets = new ArrayList<>();            for (ResolveInfo info : resInfo) {                Intent targeted = new Intent(Intent.ACTION_PICK);                targeted.setType("image/*");                ActivityInfo activityInfo = info.activityInfo;                String packageName = activityInfo.packageName;                if (activityInfo != null && packageName != null) {                    if (packageName.contains(FILE_MANAGER) || packageName.contains(GALLERY_APP)) {//FILE_MANAGER,GALLERY_APP自定义包名                        targeted.setPackage(packageName);                        targets.add(targeted);                    }                }            }//            intent = Intent.createChooser(targets.remove(0), activity.getString(R.string.vrmake_setting_chooser_title));            intent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targets.toArray(new Parcelable[]{}));        }        activity.startActivityForResult(intent, PHOTO_REQUEST_GALLERY);    }
