从主应用程序获取主活动 [英] Getting Main Activity from Main Application

问题描述

我有以下清单.

<application
    android:name=".MyMainApplication"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".MyMainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

我还具有以下全局静态函数.

I also have the following global static function.

MyMainApplication application = MyMainApplication.instance();是在各处都使用应用程序上下文中描述的技术?

我想从变量application中获取MyMainActivity吗?

推荐答案

无法使用Application实例检索应用程序的主Activity.

There is no way to retrieve the application's main Activity using the Application instance.

通常没有理由这样做……也许有比您显然在直接操作主Activity更好的解决方案.也许您应该更新您的帖子，特别说明您要尝试做的事情.

Usually there is no reason to do this... perhaps there is a better solution than manipulating the main Activity directly as you apparently are doing. Maybe you should update your post explaining specifically what you are attempting to do.
