起動時のActivityを変更する

More than 5 years have passed since last update.

AndroidManifest.xmlの編集

inter-filterタグが記述されたActivityタグ内のandroid:nameを起動時に表示したいActivity名に変更する。

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

たとえば、MainActivityからSubActivityへ変更した場合は下記のとおり。

AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.exapmle.test" >

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".subActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        <activity
            android:name=".MainActivity" >
        </activity>
    </application>
</manifest>
