translate、alpha、scaleの画面遷移アニメーション

普段あまりアニメーションをうまく使っていないので練習＋メモとして簡単な画面遷移アニメーションを紹介します。
画面遷移、ActivityのOpen、Closeまたはアニメーションタイプなどは以下のサイトで参考しました。

    android:fromYDelta="100%"
    android:toYDelta="0%"
    android:fillAfter="true"
    android:fillEnabled="true"
    android:duration="@string/activity_animation_duration"
    android:interpolator="@android:anim/accelerate_interpolator"
    />

<!-- res/anim/activity_trans_open_exit.xml -->
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"

作成したテーマをActivityに設定する

<!-- AndroidManifest.xml -->
....
    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Light.NoTitleBar"
        >
        <activity
            android:label="@string/app_name"
            android:name=".MainActivity"
            android:theme="@style/MyTheme1"
            >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
        <activity
            android:name=".SecondActivity"
            android:theme="@style/MyTheme1"
            >
        </activity>
    </application>
