使用ijkplayer播放一个网络视频

首先工程内集成这几个玩意

然后在model的gradle里边加点东西

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25



    defaultConfig {
        applicationId "com.example.weekthreetest"
        minSdkVersion 14
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }

}

repositories {
    mavenCentral()
    flatDir {
        dirs 'libs' //this way we can find the .aar file in libs folder
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    implementation 'com.android.support:appcompat-v7:25.+'
    implementation 'com.android.support.constraint:constraint-layout:1.0.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:0.5'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'

    compile(name: 'ijkplayer-java-release', ext: 'aar')
}

    PlayerManager player;
    private String url1 = "http://2449.vod.myqcloud.com/2449_bfbbfa3cea8f11e5aac3db03cda99974.f20.mp4";

    @Override

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_show);
        initPlayer();
    }
    private void initPlayer() {
        player = new PlayerManager(this);
        player.setFullScreenOnly(true);
        player.setScaleType(PlayerManager.SCALETYPE_FILLPARENT);
        player.playInFullScreen(true);
        player.setPlayerStateListener(this);
        player.play(url1);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (player.gestureDetector.onTouchEvent(event)){
            return true;
        }
        return super.onTouchEvent(event);
    }

    @Override
    public void onComplete() {

    }

    @Override
    public void onError() {

    }

    @Override
    public void onLoading() {

    }

    @Override
    public void onPlay() {

    }
}

这样基本上就能玩了

有人比较菜，那我把布局也粘上来

xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.weekthreetest.ShowActivity">
    <com.example.weekthreetest.widget.media.IjkVideoView

        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

运行效果就不放了 如果没出来只能说你没有添加网络权限
