WallpaperManager无法调整大小，并且会拉伸

Question

我有以下代码很完美，通过单击按钮，可以放置完美的墙纸，细节是将其拉伸。

如果我在android studio的模拟器上尝试完美运行，但如果在2部我拥有的手机（Sony Xpiria C2105和Samsung galaxy S3）上尝试，则壁纸会拉伸，尽管它可以很好地检测到Width和高度（以像素为单位）。

我真的不知道为什么会发生这种情况，我需要专家来查看我的失败之处。首先，谢谢。

Java：

    public class infoanimales extends AppCompatActivity {

    private RequestOptions options;
    TextView txtclose;
    LinearLayout img;
    public ProgressDialog progressDialog;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_infoanimales);

        Button btnSetWallpaper = (Button) findViewById(R.id.btn);

        btnSetWallpaper.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                new SetWallpaperTask().execute();

            }

            return result;
        }

        @Override

            super.onPostExecute(result);

            WallpaperManager wallpaperManager = WallpaperManager.getInstance(getBaseContext());
            try {
