两个发射活动 [英] Two launcher activities

问题描述

我已经打上意图过滤器两种活动

I have two activities marked with intent filter

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.package"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="7" />

<application
    android:name=".MyApp"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >

    <!-- work order activity -->
    <activity
        android:name=".app.WorkOrderActivity"
        android:label="@string/work_order"
        android:taskAffinity="com.package.task_for_work_order_activity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

    <!-- inventory activity -->
    <activity
        android:name=".app.InventoryActivity"
        android:label="@string/inventory"
        android:taskAffinity="com.package.task_for_inventory_activity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

现在的问题是，当我安装apk文件，没有显示出有活性的，因为，我的理解系统不能指定哪些活动应该显示。

The problem is, that when I'm installing apk file, there is no activity shown, because, as I understood system can't specify what activity should be shown.

我真的很需要两个发射器显示的活动，所以请不要给意见有关从次活动除去意图过滤器，或者如果你这样为我提供另一种方式展现在发射两个图标。

I just really need two activities shown in launcher, so please don't give advice about removing intent-filters from second activity, or if you do so provide me another way to show two icons in launcher.

在此先感谢。

推荐答案

您需要指定通过添加下面一行到你的意图，过滤器，它的活动是默认的：

You need to specify which activity is the default one by adding the following line to your intent-filter:

<category android:name="android.intent.category.DEFAULT"/>

插入此默认行为，并保持休息。那么它应该工作。

Insert this in the default activity and keep the rest. Then it should work.

您可能还需要添加不同的图标，你的第二个活动与属性安卓图标=@可绘制/ myothericon

You may also want to add a different icon to your 2nd activity with the attribute android:icon="@drawable/myothericon"
