两个发射器为一个单一的活动 [英] Two launchers for a single activity

问题描述

是否有可能有多个发射它启动相同的活性的不同意图演员？

Is it possible to have multiple launchers which start the same Activity with different intent extras ?

推荐答案

有没有办法开展活动（通过启动器）时提供额外的意图

There is no way to provide intent extras when launching the activity (via the Launcher).

不过，你所能做的就是用＆LT;以活动为别名＆GT; 定义更多的应用程序图标将推出相同的（目标）活动标记

However, what you can do is use <activity-alias> tags that define additional app icons that will launch the same (target) activity.

编辑：添加例如：

此示例显示了实体经济活动的呼叫 MyRealActivity 键，名为 Blahblah 的别名。双方有意向的过滤器，这将使他们出现可用的应用程序的列表中。他们有不同的标签，然后不同的图标，使他们看起来像2个不同的应用程序给用户。但是，他们都推出了同样的活动。请注意，有没有Java类 .Blahblah ，这只是一个占位符，并且必须是唯一的。

This example shows a real activity call MyRealActivity and an alias called Blahblah. Both have intent-filters that will make them appear on the list of available apps. They have different labels and different icons so that they will look like 2 different apps to the user. However, they both launch the same activity. Please note that there is no java class for .Blahblah, that is just a placeholder and must be unique.

    <activity
            android:name=".MyRealActivity"
            android:label="@string/header_application"
            android:icon="@drawable/icon_myapp">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>

    <activity-alias
            android:targetActivity=".MyRealActivity"
            android:name=".Blahblah"
            android:label="@string/header_blahblah"
            android:icon="@drawable/icon_blahblah">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity-alias>
