Intent intent= new Intent();                 intent.setAction("com.joyodream.jiji.main");                 MainActivity.this.startActivity(intent); <intent-filter>                 <action android:name="com.joyodream.jiji.main" />                 <category android:name="android.intent.category.DEFAULT" />                            </intent-filter>

第三种：通过Scheme

1 2 3 4 5 6 7 8 9 10 11

Intent intent= new Intent();                 intent.setData(Uri.parse("joyodream://......"));                 startActivity(intent); <intent-filter>                 <action android:name="android.intent.action.VIEW" />                 <category android:name="android.intent.category.DEFAULT" />                 <data android:scheme="joyodream" android:ssp="jiji" />                            </intent-filter>
