推荐答案

我使用 call INTENT 代替 WallpaperManager 来解决这个问题，如下所示:

I solve this problem using call INTENT in place of WallpaperManager like this:

//加载文件

File file = new File(getGalleryPath());

if ( file.exists()) {
     Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
     intent.addCategory(Intent.CATEGORY_DEFAULT);
     intent.setDataAndType(Uri.fromFile(file), "image/jpeg");
     intent.putExtra("mimeType", "image/jpeg");
     this.startActivity(Intent.createChooser(intent, "Set as:"));
} else {
     Log.d("TEST", "file not exixts.");
}

//获取图片路径的方法

// method for getting Image path

private static String getGalleryPath() {
    return Environment.getExternalStorageDirectory() + "/" + Environment.DIRECTORY_DCIM + "/MyImages/IMG-20160326-WA0083.jpg";   
}
