对应启动时设置?

package com.wust.myanimation;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.ViewAnimationUtils;

import android.view.animation.AlphaAnimation;

import android.view.animation.Animation;

import android.view.animation.AnimationSet;

import android.view.animation.AnimationUtils;

import android.view.animation.BounceInterpolator;

import android.view.animation.RotateAnimation;

import android.view.animation.ScaleAnimation;

import android.view.animation.TranslateAnimation;

import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

private TextView tv_hello_world;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

public void tiaozhuan(View view) {

Intent intent = new Intent(MainActivity.this, SecondActivity.class);

startActivity(intent);

//淡入 淡出 的动画效果

// overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);

//从左向右 的滑动效果

overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);

}

}

对应退出时设置

package com.wust.myanimation;

import android.os.Bundle;

import androidx.annotation.Nullable;

import androidx.appcompat.app.AppCompatActivity;

public class SecondActivity extends AppCompatActivity {

@Override

protected void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_second);

}

@Override

public void finish() {

super.finish();

//淡入 淡出 的动画效果

overridePendingTransition(android.R.anim.fade_in,android.R.anim.fade_out);

//从左向右 的滑动效果

// overridePendingTransition(android.R.anim.slide_in_left,android.R.anim.slide_out_right);

}

}

?利用自定义动画设置

第一步：在 res/anim/ 文件夹下分别创建 enter.xml 和 exit.xml 文件

// enter.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android" android:duration="1500">

<scale android:pivotX="0%p"

android:pivotY="0%p"

android:fromXScale="0%p"

android:toXScale="100%p"

android:fromYScale="0%p"

android:toYScale="100%p"/>

</set>

//exit.xml

<?xml version="1.0" enco

<set xmlns:android="http://schemas.android.com/apk/res/android" android:duration="1500">

<scale android:pivotX="0%p"

android:pivotY="0%p"

android:fromXScale="100%p"

android:toXScale="0%p"

android:fromYScale="100%p"

android:toYScale="0%p"/>

</set>

第二步：和使用系统动画一样 用起来就好了
