java墙纸未缩放到设备的显示

Question

我想通过单击按钮将图像设置为设备的壁纸

我设置了点击监听器（setWall），但图像没有缩放到设备的显示

imageBrought = getIntent().getExtras().getString("appMomentImage");         
Glide.with(getApplicationContext()).load(imageBrought).dontAnimate().into(imagePreview);

    setWall.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
           Glide.with(getApplicationContext()).load(imageBrought).asBitmap().into(new SimpleTarget<Bitmap>() {
                @Override
                public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {

                    try {

                       WallpaperManager.getInstance(getApplicationContext()).setBitmap(resource);


                    } catch (IOException e) {

                        e.printStackTrace();

                    }

                    Toast.makeText(getApplicationContext(), "Your Wallpaper Has Been Set!", Toast.LENGTH_LONG).show();

                }
            });
        }
    });

你可以用这个来获取你的设备指标，然后传递给你的图像大小

DisplayMetrics metrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(metrics);

    metrics.heightPixels;
    metrics.widthPixels;
