聲明一個Activity，使用ACTION_MAIN作為Action，CATEGORY_DEFAULT作為Category，之后在調用Activity中，引入如下代碼就可以自動生成所有匹配Action和Category的Activity的啟動菜單了。
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
Log.i("TestActivity", "Options Menu Created");
super.onCreateOptionsMenu(menu);
//menu.add(1, 0, 0, "EDIT");
// Create an Intent that describes the requirements to fulfill, to be included
// in our menu. The offering app must include a category value of Intent.CATEGORY_ALTERNATIVE.
Intent intent = new Intent(Intent.ACTION_MAIN, getIntent().getData());
intent.addCategory(Intent.CATEGORY_ALTERNATIVE);
// Search for, and populate the menu with, acceptable offering applications.
menu.addIntentOptions(
1, // Menu group
0, // Unique item ID (none)
0, // Order for the items (none)
this.getComponentName(), // The current Activity name
null, // Specific items to place first (none)
intent, // Intent created above that describes our requirements
0, // Additional flags to control items (none)
null); // Array of MenuItems that corrolate to specific items (none)
return true;
}
