Android 实现引导页视频播放效果

效果图：素材资源以QQ音乐分享代替，后续可以替换为自己需要的视频资源 

• 自定义view集成VideoView

package com.ex.theme.view;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

/**
 * @author sd
 * @date 2019/4/1
 */
public class CustomView extends VideoView {

    public CustomView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
//        计算屏幕宽高
        int width = getDefaultSize(0, widthMeasureSpec);
        int heigth = getDefaultSize(0, heightMeasureSpec);
        setMeasuredDimension(width, heigth);
    }
}
           

•  布局页面

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.ex.theme.view.CustomView
        android:id="@+id/video_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <Button
        android:id="@+id/tv_jump"
        android:text="跳过"
        android:layout_alignParentRight="true"
        android:background="@android:color/transparent"
        android:layout_margin="10dp"
        android:textSize="16sp"
        android:textColor="@color/color_green8"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

     <Button
        android:id="@+id/bt_voice"
        android:text="@string/splash_bt_voice"
        android:drawableRight="@drawable/open_voice"
        android:visibility="gone"
        android:layout_alignParentRight="true"
        android:background="@android:color/transparent"
        android:layout_margin="15dp"

        android:textColor="@color/color_green5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />


    <Button
        android:visibility="gone"
        android:id="@+id/bt_start"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="56dp"
        android:text="欢迎进入"/>

</RelativeLayout>
