Android Activity界面切换添加动画特效

在Android 2.0之后有了overridePendingTransition（） ，其中里面两个参数，一个是前一个activity的退出两一个activity的进入，

@Override
????? public void onCreate(Bundle savedInstanceState) {
????????????? super.onCreate(savedInstanceState); ?

????????????? setContentView(R.layout.SplashScreen);
?
????????????? new Handler().postDelayed(new Runnable() {
????????????????????? @Override
????????????????????? public void run() {
????????????????????????????? Intent mainIntent = new Intent(SplashScreen.this,???? AndroidNews.class);
????????????????????????????? SplashScreen.this.startActivity(mainIntent);
????????????????????????????? SplashScreen.this.finish();
?
????????????????????????????? overridePendingTransition(R.anim.mainfadein,
????????????????????????????????????? R.anim.splashfadeout);
????????????????????? }
????????????? }, 3000);
????? }?

上面的代码只是闪屏的一部分。

<set xmlns:Android="http://schemas.android.com/apk/res/android"
??????? Android:interpolator="@android:anim/decelerate_interpolator">
??? <scale Android:fromXScale="2.0" android:toXScale="1.0"
?????????? Android:fromYScale="2.0" android:toYScale="1.0"
?????????? Android:pivotX="50%p" android:pivotY="50%p"
?????????? Android:duration="@android:integer/config_mediumAnimTime" />
</set>

新建zoomout.xml文件

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:Android="http://schemas.android.com/apk/res/android"
??????? Android:interpolator="@android:anim/decelerate_interpolator"
??????? Android:zAdjustment="top">
??? <scale Android:fromXScale="1.0" android:toXScale=".5"
?????????? Android:fromYScale="1.0" android:toYScale=".5"
?????????? Android:pivotX="50%p" android:pivotY="50%p"
?????????? Android:duration="@android:integer/config_mediumAnimTime" />
??? <alpha Android:fromAlpha="1.0" android:toAlpha="0"
??????????? Android:duration="@android:integer/config_mediumAnimTime"/>
</set>
