问题

以下是您要翻译的内容：

当我将应用中的图像设置为设备的背景时，设备会放大图像并裁剪它，但我不想要那样，我希望将图像设置为相同的大小。

这里有一个简短的视频解释了我想表达的内容，仅15秒：短视频

提示：第一个是我的应用，第二个是Zedge应用，是相同的照片。
因此，当我将图像设置为壁纸时，我希望我的应用与Zedge应用的效果相似。

这是我的代码

item_home_image = findViewById(R.id.item_home_image);
item_home_image.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        if (checkPermission()) {
            final Intent intent = getIntent();
            String url = intent.getStringExtra("imageUrl");
            Picasso.with(PicassoDisplayImageAdapter.this).load(url).into(new Target() {
                @RequiresApi(api = Build.VERSION_CODES.N)
                @Override
                public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                    WallpaperManager wallpaperManager = WallpaperManager.getInstance(PicassoDisplayImageAdapter.this);
                    try {
                        wallpaperManager.setBitmap(bitmap);
                    } catch (IOException ex) {
                        ex.printStackTrace();
                    }
                    Toasty.normal(PicassoDisplayImageAdapter.this, "تم تغيير الخلفية بنجاح", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onBitmapFailed(final Drawable errorDrawable) {
                    Toasty.error(PicassoDisplayImageAdapter.this, "فشل تحميل الصورة", Toast.LENGTH_SHORT).show();
                }

                @Override
                public void onPrepareLoad(final Drawable placeHolderDrawable) {
                    Toasty.normal(PicassoDisplayImageAdapter.this, "جاري التحميل", Toast.LENGTH_SHORT).show();
                }
            });
        }
     }
});

从我的应用中设置图像时的效果

从Zedge应用中设置图像时的效果

item_home_image = findViewById(R.id.item_home_image);
item_home_image.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (checkPermission()) {
final Intent intent = getIntent();
String url = intent.getStringExtra("imageUrl");
Picasso.with(PicassoDisplayImageAdapter.this).load(url).into(new Target() {
@RequiresApi(api = Build.VERSION_CODES.N)
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
WallpaperManager wallpaperManager = WallpaperManager.getInstance(PicassoDisplayImageAdapter.this);
try {
wallpaperManager.setBitmap(bitmap);
} catch (IOException ex) {
ex.printStackTrace();
}
Toasty.normal(PicassoDisplayImageAdapter.this, "تم تغيير الخلفية بنجاح", Toast.LENGTH_SHORT).show();
}
@Override
public void onBitmapFailed(final Drawable errorDrawable) {
Toasty.error(PicassoDisplayImageAdapter.this, "فشل تحميل الصورة", Toast.LENGTH_SHORT).show();
}
@Override
public void onPrepareLoad(final Drawable placeHolderDrawable) {
Toasty.normal(PicassoDisplayImageAdapter.this, "جاري التحميل", Toast.LENGTH_SHORT).show();
}
});
}
}
});

我找到了一个解决方案，而且比这个更好：

// 设置主屏幕壁纸图像
public void setHomeWallpaper() {
    BitmapDrawable bitmapDrawable = ((BitmapDrawable) imageView.getDrawable());
    Bitmap bitmap = bitmapDrawable.getBitmap();
    String bitmapPath = Images.Media.insertImage(getContentResolver(), bitmap, "", null);
    Uri bitmapUri = Uri.parse(bitmapPath);
    Intent intent = new Intent(Intent.ACTION_ATTACH_DATA).setDataAndType(bitmapUri, "image/jpeg")
            .addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
            .putExtra("mimeType", "image/jpeg");
    startActivity(Intent.createChooser(intent, getString(R.string.background)));
    Toast.makeText(PicassoDisplayImageAdapter.this, "قم بإختيار التطبيق المناسب لتعيين الصورة", Toast.LENGTH_SHORT).show();
}

    // Set Home wallpaper the image
public void setHomeWallpaper () {
BitmapDrawable bitmapDrawable = ((BitmapDrawable) imageView.getDrawable());
Bitmap bitmap = bitmapDrawable.getBitmap();
String bitmapPath = Images.Media.insertImage(getContentResolver(), bitmap, "", null);
Uri bitmapUri = Uri.parse(bitmapPath);
Intent intent = new Intent(Intent.ACTION_ATTACH_DATA).setDataAndType(bitmapUri,  "image/jpeg")
.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
.putExtra("mimeType", "image/jpeg");
startActivity(Intent.createChooser(intent, getString(R.string.background)));
Toast.makeText(PicassoDisplayImageAdapter.this, "قم بإختيار التطبيق المناسب لتعيين الصورة", Toast.LENGTH_SHORT).show();
}

public void getBitmapFromURL(String path) {

    Glide.with(WaalDetail.this)
            .asBitmap()
            .load(path)
            .into(new SimpleTarget<Bitmap>() {
                @Override
                public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                    try {
                        WallpaperManager.getInstance(getApplicationContext()).setBitmap(resource);
                        Toast.makeText(WaalDetail.this, "Set wallpaper successfully!", Toast.LENGTH_LONG).show();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                }
            });
}

this is works for me perfectly.

 public void getBitmapFromURL(String path) {
Glide.with(WaalDetail.this)
.asBitmap()
.load(path)
.into(new SimpleTarget<Bitmap>() {
@Override
public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
try {
WallpaperManager.getInstance(getApplicationContext()).setBitmap(resource);
Toast.makeText(WaalDetail.this, "Set wallpaper successfully!", Toast.LENGTH_LONG).show();
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
