要在Uri.parse中传递的图像路径，以使用意图打开图像

Question

我正在尝试使用意图打开一个图像。我存储中图像的路径是 /storage/emulated/0/nitp/download/logo.png.

我的代码是

Intent intent = new Intent();
intent.setAction(Intent.ACTION_DEFAULT);
intent.setDataandType(Uri.parse("/storage/emulated/0/nitp/download/logo.png"),"image/*");
startActivity(intent);

我也尝试把文件：//存储/仿真/0/nitp/下载/logo.png和内容：//存储/仿真/0/nitp/下载/logo.png

我应该走哪条路？

解决了必须使用file:///storage/emulated/0/nitp/downloads/logo.png

对于从媒体存储或SD卡拾取图像：

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);

获取图像的路径并在ImageView中设置：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
        Uri filePath = data.getData();
        try {
            //Getting the Bitmap from Gallery
            imgpath= MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
            //Setting the Bitmap to ImageView
            imageViewProfileImage.setImageBitmap(imgpath);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

希望这能奏效。
