Question

这就是我的问题。对于不知道我在问什么的人来说,我想让这个菜单出现在我的应用程序中,“http://db.tt/GQX9GBYF” rel=“norefererr”>http://db.tt/GQX9GBYF 。事实是,我不知道如何做到这一点。我认为我必须创造一种意图,从中获取图像路径,然后将它设置为背景。但是我不知道这样做的确切方法。

拜托,谁能给我举个例子??????????????????

我不得不说,我通过启动本地画廊应用程序做到了这一点, 但我也想设置活墙纸

Answer 1

您 Intent.ACTION_SET_WALLPAPER 用于启动用于选择壁纸的 ContaxtMenu 代码 :

Intent intent = new Intent(Intent.ACTION_SET_WALLPAPER);
startActivity(Intent.createChooser(intent, "Select Wallpaper"));

Answer 2

Currently I m working on the same thing. The accepted answer is correct but if you want to use wallpaper as your app s background, then you have to use Wallpaper theme & call the Intent.Action_Set_Wallpaper to pick wallpaper.

public void onCreate(Bundle savedInstanceState) {

 Activity.this.setTheme(android.R.style.Theme_Wallpaper);

super.onCreate(savedInstanceState);
setContentView(/*some layout*/);
}

//在单击按钮时单击

Intent intent = new Intent(Intent.ACTION_SET_WALLPAPER);
startActivity(Intent.createChooser(intent, "Select Wallpaper"));
