Android酷炫欢迎页播放视频,仿蚂蜂窝自由行和慕课网

今天无意间看到了蚂蜂窝自由行的app，启动页很酷炫。我记得以前慕课网有个版本的app欢迎页也是播放视频的。今天就顺手写一个，代码比较简单，高手请略过。

先看效果图：

一.资源准备

三个比较短小的视频：视频下载

二.开始编写代码

• 1.在项目的res下新建一个raw文件夹，放入准备好的这三个视频

• 2.自定义播放视频的CustomVideoView 
  在这个自定义View里面提供一个播放视频的方法。用户只需要传入播放路径就可以了，并且可一循环播放。

package cn.bluemobi.dylan.welcomevideopager;import android.content.Context;import android.media.MediaPlayer;import android.net.Uri;import android.util.AttributeSet;import android.view.View;import android.widget.VideoView;/** * 可以播放视频的View * Created by yuandl on 2016-11-10. */public class CustomVideoView extends VideoView {    public CustomVideoView(Context context) {        super(context);    }    public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);    }    public CustomVideoView(Context context, AttributeSet attrs) {        super(context, attrs);    }    @Override    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        super.onMeasure(widthMeasureSpec, heightMeasureSpec);        setMeasuredDimension(View.MeasureSpec.getSize(widthMeasureSpec), View.MeasureSpec.getSize(heightMeasureSpec));    }    /**     * 播放视频     *     * @param uri 播放地址     */    public void playVideo(Uri uri) {        if (uri == null) {            throw new IllegalArgumentException("Uri can not be null");        }        /**设置播放路径**/        setVideoURI(uri);        /**开始播放**/        start();        setOnPreparedListener(new MediaPlayer.OnPreparedListener() {            @Override            public void onPrepared(MediaPlayer mp) {                /**设置循环播放**/                mp.setLooping(true);            }        });        setOnErrorListener(new MediaPlayer.OnErrorListener() {            @Override            public boolean onError(MediaPlayer mp, int what, int extra) {                return true;            }        });    }}

• 3.建立没个欢迎页面的Fragment去加载自定义视频View的视图

package cn.bluemobi.dylan.welcomevideopager;import android.net.Uri;import android.os.Bundle;import android.support.annotation.Nullable;import android.support.v4.app.Fragment;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;/** * Created by yuandl on 2016-11-10. */public class GuildFragment extends Fragment {    private CustomVideoView customVideoView;    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        customVideoView = new CustomVideoView(getContext());        /**获取参数，根据不同的参数播放不同的视频**/        int index = getArguments().getInt("index");        Uri uri;        if (index == 1) {            uri = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + R.raw.guide_1);        } else if (index == 2) {            uri = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + R.raw.guide_2);        } else {            uri = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + R.raw.guide_3);        }        /**播放视频**/        customVideoView.playVideo(uri);        return customVideoView;    }    /**     * 记得在销毁的时候让播放的视频终止     */    @Override    public void onDestroy() {        super.onDestroy();        if (customVideoView != null) {            customVideoView.stopPlayback();        }    }}

• 4.界面布局
