我的应用程序显示一张图片，然后将其设置为墙纸设备。

我有代码，并且已经在某些设备上尝试过并成功运行。（联想 Vibe C Lolipop，Advan I7 Marshmallow）

但我在设备 Xiaomi Redmi 5 (Nougat) 上发现了一个问题

当我通过意图选择器将图片设置为壁纸时，没有“图库”选项

注意：我认为在小米上，Gallery Option 是设置图片作为设备壁纸的最佳选择。

我附上了Lenovo Vibe C（有图库选项）和小米红米5（没有图库选项）的截图

联想和小米的截图

下面是我的代码片段

//I have picture in "Wallpaper Folder", its name is "IMG_Wallpaper.jpg"
File folderPict = new File(Environment.getExternalStorageDirectory() + File.separator + "Wallpaper Folder");

String pictName = "IMG_Wallpaper.jpg";
String destFileName = folderPict.getAbsolutePath() + "/" + pictName;

filePict = new File(destFileName);


// In this step, I already have filePict "IMG_Wallpaper.jpg" in folder "folderPict"


//get uri from external file
Uri uriPict = Uri.fromFile(filePict);

//set wallpaper by intent chooser
Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
intent.setDataAndType(uriPict, "image/*");
intent.putExtra("mimeType", "image/*");
startActivity(Intent.createChooser(intent, "Set as"));

Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent , RESULT_GALLERY );

并用于接收结果

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (null != data) {
        imageUri = data.getData();
        //Do whatever that you desire here. or leave this blank
    }
}
