设置手机壁纸的图像视图

Question

使用Android Gallery的人，刚刚让它工作，但我试图弄清楚如何让画廊中的选定图像设置为手机的壁纸，通过点击一个按钮。任何帮助都是非常感谢的。这是代码；

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.gallery);

    imgView = (ImageView) findViewById(R.id.ImageView01);
    imgView.setBackgroundResource(Imgid[0]);

    gallery = (Gallery) findViewById(R.id.examplegallery);
    gallery.setAdapter(new AddImgAdp(this));

    gallery.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView parent, View v, int position,
                long id) {
            imgView.setBackgroundResource(Imgid[position]);
        }
    });

}

Button btn = (Button) findViewById(R.id.button3);

    btn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

        }
    });


public class AddImgAdp extends BaseAdapter {
    int GalItemBg;
    private Context cont;

    public AddImgAdp(Context c) {
        cont = c;
        TypedArray typArray = obtainStyledAttributes(R.styleable.GalleryTheme);
        GalItemBg = typArray.getResourceId(
                R.styleable.GalleryTheme_android_galleryItemBackground, 0);
        typArray.recycle();
    }

    public int getCount() {
        return Imgid.length;
    }

    public Object getItem(int position) {
        return position;
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        ImageView imgView = new ImageView(cont);

        imgView.setImageResource(Imgid[position]);
        imgView.setLayoutParams(new Gallery.LayoutParams(80, 70));
        imgView.setScaleType(ImageView.ScaleType.FIT_XY);
        imgView.setBackgroundResource(GalItemBg);

        return imgView;
    }
}

}

使用墙纸管理器：

try {
    // Set background from a resource
    WallpaperManager.getInstance(this).setResource(R.drawable.bg);
    // or set background from a bitmap
    WallpaperManager.getInstance(this).setBitmap(mBitmap);

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
