activity切換添加動畫

定義動畫xml

1.activity進入效果fade.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:fromXDelta="0"
    android:toXDelta="0" />

2.activity出去效果hold.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:fromAlpha="0.0"
    android:toAlpha="1.0" />

3.在activity跳轉時調用

Intent intent = new Intent(SplashActivity.this,
     MainActivity.class);
    SplashActivity.this.startActivity(intent);
    overridePendingTransition(R.anim.fade, R.anim.hold);//這句話是關鍵
    SplashActivity.this.finish();
