在我的活动中,我想启动一个扩展 AndroidApplication 类的类,但我不知道该怎么做。我当然想调用AndroidApplication类的onCreate方法。

public class MainActivity extends Activity
{
@Override
public void onCreate(Bundle bundle)
{
    super.onCreate(bundle);
    setContentView(R.layout.layout);
    new AndroidLauncher();
}
}  

这是清单:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.example.utente.morramongame"
      android:versionCode="1"
      android:versionName="1.0">

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="25"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/GdxTheme">

    <application
        android:name=".AndroidLauncher">
    </application>

    <activity
        android:name=".MainActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:label="@string/app_name"
        android:screenOrientation="landscape">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

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

</application>
