墙纸不适合三星设备

Question

我想通过应用程序为所有设备设置墙纸，但问题是我的以下方法适用于 Moto、sony、micromax 但不适用于 any三星 设备，如 samsung S3、samsung duos、Tab 等，在这些设备中，墙纸放大很多，请参见屏幕截图。

请指导我解决这个问题。

private void setMyWallpaper() {

    WallpaperManager myWallpaperManager = WallpaperManager
            .getInstance(getApplicationContext());

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

    // get the height and width of screen
    int height = metrics.heightPixels;
    int width = metrics.widthPixels;

    Drawable drawable = null;

    if (who.equals("color"))
        drawable = getResources().getDrawable(colorWallpaper[i]);
    else
        drawable = getResources().getDrawable(grayWallpaper[i]);
    Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap();

    Bitmap wallpaper = Bitmap.createScaledBitmap(bitmap, width, height,true);
    myWallpaperManager.suggestDesiredDimensions(width, height);
    try {
        myWallpaperManager.setBitmap(wallpaper);
        Log.i("Wall", "Wallpaper set successfully ");
    } catch (IOException e) {
        e.printStackTrace();
    }

}

我使用调用 INTENT 代替 WallpaperManager 解决了这个问题，如下所示：

//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

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