android開發(fā)之簡單視頻播放器（VideoView）

簡單視頻播放器的使用
一、簡單使用videoView和MediaController實(shí)現(xiàn)播放控制
1、添加需要的權(quán)限

 <uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION"></uses-permission>

2、設(shè)置布局

 <VideoView
            android:id="@+id/main_video"
            android:layout_width="match_parent"
            android:layout_height="240dp"
            />

3、實(shí)例化VideoView

VideoView  videoView = (VideoView) findViewById(R.id.main_video);
      MediaController  controller = new MediaController(this);//實(shí)例化控制器
//        String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"jiaoxue.mp4";
        /**
         * 本地播放
         */
//        videoView.setVideoPath("path");
        /**
         * 網(wǎng)絡(luò)播放
         */
        videoView.setVideoURI(Uri.parse("http://192.168.1.109:8080/video/jiaoxue.mp4"));

        /**
         * 將控制器和播放器進(jìn)行互相關(guān)聯(lián)
         */
        controller.setMediaPlayer(videoView);
        videoView.setMediaController(controller);

二、自定義播放器 （貼上源碼）

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.zzj.myeasyvideoplaydemo.MainActivity">

    <RelativeLayout

        android:layout_width="match_parent"
        android:layout_height="240dp">

            android:layout_width="match_parent"

            />
        <LinearLayout
            android:layout_width="match_parent"

            android:orientation="vertical"
            android:layout_alignParentBottom="true"
            >
            <SeekBar
                android:layout_width="match_parent"
                android:layout_height="5dp"
                android:layout_marginLeft="-20dp"
                android:layout_marginRight="-20dp"
                android:max="100"
                android:indeterminate="false"
                android:progress="20"
                />
            <RelativeLayout
