Question

这是我的Android清单，由于某些原因，我的MainActivity不会首先启动。每当我运行应用程序时首先启动的活动是RegisterActivity。任何人都可以帮我找出原因吗？

这是因为您在RegisterActivity

中保留了此属性

android:launchMode="singleTop"

删除所有活动中的所有这些启动模式。只保留在MainActivity中：

<activity
            android:name="com.indigohate.MainActivity"
            android:label="@string/app_name"
            android:launchMode="singleTop" 
 >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

起始活动包含<category android:name="android.intent.category.LAUNCHER" />，以确保在应用启动时它是launcher活动。

如何在android清单中正确指定我的开始活动？
