如果打开图库并选择“图像”并与我的应用共享，如何获取图像的Uri

Answer 1

打开图库以获取Image Uri

 private static final int REQUEST_SELECT_IMAGE = 100;

  private void handleOpenGallery() {
        Intent intentSelect = new Intent(Intent.ACTION_GET_CONTENT);
        intentSelect.setType("image/*");
        startActivityForResult(Intent.createChooser(intentSelect, getString(R.string.select_picture)),
                REQUEST_SELECT_IMAGE);
    }

所选图片的Uri

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_SELECT_IMAGE) {
        if (resultCode == Activity.RESULT_OK) {
            Uri uri = data.getData();
            shareImage(uri);
        }
    }
}

分享图片

  private void shareImage(Uri imageUri) {
        Intent shareIntent = new Intent();
        shareIntent.setAction(Intent.ACTION_SEND);
        shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
        shareIntent.setType("image/jpeg");
        startActivity(Intent.createChooser(shareIntent, "Share to"));
    }

Answer 2

您可以按照Raghu的以下代码打开画廊，

如果您只想打开图库，则可以使用

Intent intentSelect = new Intent(Intent.ACTION_PICK);

如果操作系统版本高于棉花糖（6.0），则添加对读/写权限的检查

如果仍然没有获取uri，则在onActivityResult中获取uri try the getPath method from here

添加检查Android OS版本是否高于Nougat（7.0），如高于Nougat一样，在获取文件uri时，您可能会收到“ FileUriExposedException” refer this link for more info
