<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.android.apis">    <application android:name="ApiDemosApplication"            android:label="@string/activity_sample_code"            android:icon="@drawable/app_sample_code" >        <activity android:name="ApiDemos">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.DEFAULT" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <activity android:name=".app.HelloWorld" android:label="@string/activity_hello_world">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.SAMPLE_CODE" />            </intent-filter>        </activity>        <activity android:name=".app.DialogActivity"                android:label="@string/activity_dialog"                android:theme="@android:style/Theme.Dialog">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.SAMPLE_CODE" />            </intent-filter>        </activity>

如上所示的一个ActionManifest.xml 则：

Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);        mainIntent.addCategory(Intent.CATEGORY_SAMPLE_CODE);        PackageManager pm = getPackageManager();        List<ResolveInfo> list = pm.queryIntentActivities(mainIntent, 0);        for (int i = 0; i < len; i++) {            ResolveInfo info = list.get(i);            CharSequence labelSeq = info.loadLabel(pm);            System.out.println("===="+labelSeq.toString()+"===="+info.activityInfo.name+"=========="+info.activityInfo.applicationInfo.packageName);        }

则结果为：

=App/Activity/HelloWorld====com.example.android.apis.app.HelloWorld==========com.example.android.apis =App/Activity/Dialog====com.example.android.apis.app.DialogActivity==========com.example.android.apis
