推荐答案

您可以在活动的意图过滤器中添加自定义操作，然后通过指定操作来启动该活动

You can add custom Action in intent-filter of you activity and start that activity by specifying action

<activity android:name="my.package.MyActivity">
    <intent-filter>
        <action android:name="my.package.action.MY_ACTION"/>
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="my.package"/>
    </intent-filter>
</activity>

使用以下代码开始活动:

start activity with this code:

final Intent intent = new Intent("my.package.action.MY_ACTION");
intent.addCategory(getActivity().getPackageName());
startActivity(getActivity(), intent);
