Android13-图片视频选择器

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：

    @Override
    protected 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() {
            @Override
            public 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.
                        }
                    }
                }
            }
        });
