Android的 - 意向打开窗口小部件的上下文菜单 [英] Android - Intent that open widget context menu

问题描述

在我的应用我想，当用户点击一个按钮，在应用程序关闭本身并自动打开添加新的widget上下文菜单。
我在做这样的：

in my application I want that when a user click a button the application closes itself and automatically opens the add new widget context Menu. I'm making this:

if (viewId == R.id.bt_homeScreen) {
        finish();
        try {
            Intent intent = new Intent(Intent.ACTION_MAIN);
            intent.addCategory(Intent.CATEGORY_HOME);
            startActivity(intent);
        } catch (ActivityNotFoundException e) {
            Toast.makeText(this.getApplicationContext(), getResources().getString(R.string.homeClientAlert), Toast.LENGTH_SHORT).show();
        }
    }

这蒙山code的问题是，我只能到手机的主屏幕：

The problem whith this code is that I only go to the phone Home screen:

我想，当我启动意图不言而喻到主屏幕，并打开窗口小部件的上下文菜单：

I want that when I launch the Intent it goes to the Home screen and open the widget context menu:

推荐答案

看看Commonsware的回答这个问题：<一href=\"http://stackoverflow.com/questions/10449884/add-widget-to-homescreen-from-android-application\">Add小部件从Android应用程序主萤幕

Take a look at Commonsware's answer to this question: Add widget to homescreen from Android application

您将能够显示部件选择菜单，但你将无法处理在一个正常的应用程序，选择。这使得使用appwidget选择必须实现AppWidgetHost中的应用。主屏幕上的应用程序都属于这一类，没有正常的应用程序。

You will be able to show the widget selection menu but you won't be able to process that selection in a normal app. The application that makes use of an appwidget selection must implement an AppWidgetHost. Home screen apps fall into this category, no normal apps.
