Android自动生成启动Activity的特定按钮

Android自动生成启动Activity的特定按钮声明一个Activity，使用ACTION_MAIN作为Action，CATEGORY_DEFAULT作为Category，之后在调用Activity中，引入如下代码就可以自动生成所有匹配Action和Category的Activity的启动菜单了。
@Override
public boolean onCreateOptionsMenu(Menumenu) {
Log.i("TestActivity","OptionsMenuCreated");
super.onCreateOptionsMenu(menu);
//menu.add(1,0,0,"EDIT");

//CreateanIntentthatdescribestherequirementstofulfill,tobeincluded
//inourmenu.TheofferingappmustincludeacategoryvalueofIntent.CATEGORY_ALTERNATIVE.
Intentintent=newIntent(Intent.ACTION_MAIN,getIntent().getData());
intent.addCategory(Intent.CATEGORY_ALTERNATIVE);

//Searchfor,andpopulatethemenuwith,acceptableofferingapplications.
menu.addIntentOptions(
1,//Menugroup
0,//UniqueitemID(none)
0,//Orderfortheitems(none)
this.getComponentName(),//ThecurrentActivityname
null,//Specificitemstoplacefirst(none)
intent,//Intentcreatedabovethatdescribesourrequirements

returntrue;
}
