推荐答案

步骤1：获取附加到ImageView的图像。

Step 1: Get the image attached to the ImageView.

Setp 2：将该图片设为壁纸。

Step 3：在 AndroidManifest.xml 中添加权限以设置壁纸！

Step 3: Add permission in the AndroidManifest.xml to set wallpaper!

对于第1步检查< a href =https://stackoverflow.com/a/8306648/1773155>这个答案！

imageView.buildDrawingCache();
Bitmap bmap = imageView.getDrawingCache();

对于第2步：

WallpaperManager m=WallpaperManager.getInstance(this);

try {
    m.setBitmap(bmap);
} catch (IOException e) {
    e.printStackTrace();
}

对于第3步：
也包含此权限。

For step 3: Include this permission too.

<uses-permission android:name="android.permission.SET_WALLPAPER" />
