Launcher 中 Home按钮不能运行

Question

我创建了一个 Android Launcher，可以正常的运行。现在的问题是当我点击 HOME 按钮时，不能直接跳到HOME 页面。如何实现呢？

Manifest file:

Answer 1

您需要指定您的活动为主屏幕，并确保它具有相应的类别，如下所示：

<activity
        android:name=".testingactivity.CoverFlowTestingActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

在上面的代码中，我们指定了一个活动名称为 "CoverFlowTestingActivity"，并为它添加了"android.intent.action.MAIN"和 "android.intent.category.HOME" 的意图过滤器。这样做会使您的活动成为主屏幕，并在点击 HOME 按钮时显示。
