我希望在我的应用程序上加载动画，但是我的应用程序大部分都是片段，这是我的代码请帮助我，因为我希望用户看到的第一件事是动画消失一段时间后

使用以下代码制作启动画面：

在res> drawable文件夹内，添加一个标题为splash.xml的新的drawable资源文件

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@color/colorPrimary"/>

<item>
    <bitmap android:src="@drawable/logo"
        android:gravity="center"/>
</item>
</layer-list>

在values> styles.xml中，粘贴以下内容：

<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowBackground">@drawable/splash</item>
</style>

然后创建一个Java类SplashActivity.java

package com.example.android.motouch3;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
public class SplashActivity extends AppCompatActivity {

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = new Intent(this, MainActivity.class);
    startActivity(intent);
    finish();
}
}

现在，当用户打开应用程序时，带有徽标的启动屏幕将弹出几秒钟，然后恢复到正常屏幕。

我想要在片段上加载动画屏幕，如启动屏幕
