【安卓】视频播放器实现过程，超详细注释，自定义视频进度条，打开本地文件播放视频等功能。
一、实现效果
废话不多说，直接上代码，里面有详细注释，不清楚的评论区留言。
二、布局代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:background="@color/background"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical">
<ImageButton
android:id="@+id/video_file"
android:layout_width="12dp"
android:layout_height="12dp"
android:background="@mipmap/video_file"/>
<TextView
android:id="@+id/open_video"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@color/white"
android:clickable="true"
android:textSize="8dp"
android:text="本地视频"/>
LinearLayout>
<VideoView

android:textColor="@color/white"/>
<SeekBar
android:layout_width="0dp"

/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/seekbar_max_second"
android:text="0"

RelativeLayout>
三、Activity代码
package com.example.tabtest.activity;

import android.content.pm.ActivityInfo;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import android.view.View;
import android.widget.ImageButton;
import android.widget.SeekBar;
import android.widget.TextView;
import android.widget.VideoView;
import com.example.tabtest.R;
import com.example.tabtest.util.FormatTime;

/**

自定义一个进度条时间转换工具类，超简单
public class FormatTime {
public String SecondToTime(int seconds){
int second = seconds % 60;
int m = seconds / 60;
int h = seconds /60 /60;
return h+":"+m+":"+second;
}
}
