Android13-图片视频选择器

news 2025/8/5 4:40:05

在compileSDK = 33 时，谷歌在安卓新增了图片选择器功能，支持单选、多选、选图片、视频等操作，并且不需要额外获取照片/音频权限。

具体实现如下：

1：请求

        Log.d(TAG, "Build.VERSION.SDK_INT" + Build.VERSION.SDK_INT);if (Build.VERSION.SDK_INT >= 33) {//图片选择器单选
//            Intent intent = new Intent(MediaStore.ACTION_PICK_IMAGES);
//           在complieSDK32已废弃
//            startActivityForResult(intent,  PHOTO_PICKER_REQUEST_CODE);//图片选择器多选final int maxNumPhotosAndVideos = 3;Intent intent = new Intent(MediaStore.ACTION_PICK_IMAGES);
//            intent.setType("video/*");//仅选择视频intent.setType("image/*");//仅选择图片intent.putExtra(MediaStore.EXTRA_PICK_IMAGES_MAX, maxNumPhotosAndVideos);launcher.launch(intent);} else {//我们需要自己开发}

2：响应

2.1单选：

    @Overrideprotected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {super.onActivityResult(requestCode, resultCode, data);if (resultCode == RESULT_OK) {if (requestCode == PHOTO_PICKER_REQUEST_CODE) {Uri currentUri = null;if (data != null) {currentUri = data.getData();binding.image.setImageURI(currentUri);}Log.d(TAG, "currentUri:" + currentUri);}}}

2.2多选：

        launcher = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(),new ActivityResultCallback<ActivityResult>() {@Overridepublic void onActivityResult(ActivityResult result) {if (result != null) {if (result.getData() != null && result.getResultCode() == RESULT_OK) {Intent intent = result.getData();for (int i = 0; i < intent.getClipData().getItemCount(); i++) {Uri uri = intent.getClipData().getItemAt(i).getUri();Log.d(TAG, "multiple current Uri:" + uri);// Do stuff with each photo/video URI.}}}}});
