如何以正确的方式将Activity添加到manifest.xml? [英] How to add Activity to manifest.xml in right way?

问题描述

我应该在android清单中编写每个活动，如何进行?每个活动都必须有意图过滤器吗?

should I write each activity in android manifest and how? Must each activity have intent-filter, or not?

推荐答案

在清单文件中添加活动的多种方法.

Multiple ways to add activites in Manifest file.

意图过滤器不是所有活动的必需标记，它是可选的.

intent filter is not a necessary tag for all activites,it is optional.

在清单的应用程序标记中添加活动:

Add Activity in application tag in your manifest:

 <!-- Main Activity-->
    <activity android:name=".YourActivityName" >
        <intent-filter>
      <!-- MAIN represents that it is the Main Activity-->
            <action android:name="android.intent.action.MAIN" />
      <!-- Launcher Denotes that it will be the first launching activity-->
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
 <!--Add Other activities like this-->
    <activity android:name=".YourActivityName2" >
 <!--Default Intent Filter-->
        <intent-filter>
            <action android:name="android.intent.action.DEFAULT" />
        </intent-filter>
    </activity>
 <!--OR Other activities like this And  intent filter is not necessary in other activites-->
    <activity android:name=".YourActivityName3" >
    </activity>
 <!--OR Add Other activities like this-->
    <activity android:name=".YourActivityName4" />
