推荐答案

哈哈哈..这个答案即将有点晚了。 ;-)不过，我不认为它已经答对尚未所以这里去...我收集哪些是你要启动的壁纸选择器。有两种方法可以做到这一点，这取决于Android版本，你会看到下面。您只能16版本后，指定你的壁纸否则，启动选择器，用户指定的墙纸。

Hahaha.. This answer is coming a little late. ;-) But, I don't think it's been answered correctly yet so here goes... What I gather is that you want to launch the wallpaper chooser. There's two ways to do that depending on which android version, you'll see below. You can only specify YOUR wallpaper after version 16. Otherwise, you launch the chooser and the user specifies the wallpaper.

   if (android.os.Build.VERSION.SDK_INT >= 16)
    {
        Intent intent = new Intent("android.service.wallpaper.CHANGE_LIVE_WALLPAPER");
        intent.putExtra("android.service.wallpaper.extra.LIVE_WALLPAPER_COMPONENT", new ComponentName(getApplicationContext().getPackageName(), (new StringBuilder(String.valueOf(getApplicationContext().getPackageName()))).append(".LiveWallpaper").toString()));


        try
        {
            startActivity(intent);
            finish();
            return;
        }
        catch (ActivityNotFoundException activitynotfoundexception)
        {
            activitynotfoundexception.printStackTrace();
        }
        return;
    }
    Intent intent1 = new Intent();
    intent1.setAction("android.service.wallpaper.LIVE_WALLPAPER_CHOOSER");
    try
    {
        startActivity(intent1);
    }
    catch (ActivityNotFoundException activitynotfoundexception1)
    {
        activitynotfoundexception1.printStackTrace();
        Toast.makeText(getApplicationContext(), "Live Wallpapers not supported", 1).show();
    }
    finish();
