Android 仿今日頭條的視頻播放控件（幾行代碼快速實現）

前段時間由於項目需要用到類似於今日頭條的視頻播放器，實現在線播放，邊緩存邊播放，當然也可以播放本地文件，如下圖：

這裏我推薦大家使用的是jiecaovideoplayer開源庫，這個庫的播放引擎是ijkplayer，它調用ffmpeg， 原項目GitHub地址：https://github.com/lipangit/JieCaoVideoPlayer
一、項目引入：
1、添加類庫

compile 'fm.jiecao:jiecaovideoplayer:4.8.3'
compile 'com.github.bumptech.glide:glide:3.7.0'

2、添加布局

 <fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard
        android:id="@+id/player_list_video"
        android:layout_width="match_parent"
        android:layout_height="220dp" />

3、下面就是我所說的通過設置視頻地址、縮略圖地址、標題等幾行代碼快速實現視頻的播放啦

 JCVideoPlayerStandard player = (JCVideoPlayerStandard) findViewById(R.id.player_list_video);
        boolean setUp = player.setUp("http://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4", JCVideoPlayer.SCREEN_LAYOUT_LIST, "");
        if (setUp) {
            Glide.with(MainActivity.this).load("http://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg").into(player.thumbImageView);
        }

4、在Activity中

@Override
    public void onBackPressed() {
        if (JCVideoPlayer.backPress()) {
            return;
        }
        super.onBackPressed();
    }

    @Override
    protected void onPause() {
        super.onPause();
        JCVideoPlayer.releaseAllVideos();
    }

5、還有一點不要忘記哦，要添加權限滴：

<!--聯網權限-->
    <uses-permission android:name="android.permission.INTERNET" />

下面我們來看看我們運行效果：

二、如何使用jiecaovideoplayer播放本地視頻
注意：jiecaovideoplayer支持file:///開頭的文件播放，但是不支持assets或者raw目錄下的視頻，assets下的視頻要先複製到本地路徑才能播放，至於怎麼監聽播放完全呢，要繼承JCvideoPlayerStandard 複寫onAutoCOmplete函數

三、模擬用戶點擊開始按鈕，直接進入全屏

 //直接進入全屏
        player.startFullscreen(this, JCVideoPlayerStandard.class, videoUrl, "");
        //模擬用戶點擊開始按鈕，NORMAL狀態下點擊開始播放視頻，播放中點擊暫停視頻
        player.startButton.performClick();

我把代碼都貼出來吧：

package la.trytry.jiecaovideoplayer;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.bumptech.glide.Glide;

import fm.jiecao.jcvideoplayer_lib.JCVideoPlayer;
import fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard;

public class MainActivity extends AppCompatActivity {
    private String videoUrl = "http://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4";
    private JCVideoPlayerStandard player;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        player = (JCVideoPlayerStandard) findViewById(R.id.player_list_video);
        boolean setUp = player.setUp(videoUrl, JCVideoPlayer.SCREEN_LAYOUT_LIST, "");
        if (setUp) {
            Glide.with(MainActivity.this).load("http://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg").into(player.thumbImageView);
        }

        //直接進入全屏
        player.startFullscreen(this, JCVideoPlayerStandard.class, videoUrl, "");
        //模擬用戶點擊開始按鈕，NORMAL狀態下點擊開始播放視頻，播放中點擊暫停視頻
        player.startButton.performClick();
    }

    @Override
    public void onBackPressed() {
        if (JCVideoPlayer.backPress()) {
            return;
        }
        super.onBackPressed();
    }

    @Override
    protected void onPause() {
        super.onPause();
        JCVideoPlayer.releaseAllVideos();
    }

}

四、下面回到我們的主題上，實現仿今日頭條的視頻播放
1、VideoActivity.Java

package la.trytry.jiecaovideoplayer;

import android.graphics.Rect;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.AbsListView;
import android.widget.ListView;

import java.util.ArrayList;

import fm.jiecao.jcvideoplayer_lib.JCVideoPlayer;
import fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard;

public class VideoActivity extends AppCompatActivity {
    private String videoUrl = "http://gslb.miaopai.com/stream/ed5HCfnhovu3tyIQAiv60Q__.mp4";
    private ListView listView;
    private ArrayList<String> datas;
    private JCVideoPlayerStandard currPlayer;
    private VideoAdapter adapter;
    private AbsListView.OnScrollListener onScrollListener;
    private int firstVisible;//當前第一個可見的item
    private int visibleCount;//當前可見的item個數

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video);
        listView = (ListView) findViewById(R.id.listview);
        initDatas();
        initListener();
    }

    private void initDatas() {
        datas = new ArrayList<String>();
        for (int i = 0; i < 20; i++) {
            datas.add(videoUrl);
        }
        adapter = new VideoAdapter(VideoActivity.this, datas, R.layout.item_video);
        listView.setAdapter(adapter);
    }

    /**
     * 滑動監聽
     */
    private void initListener() {
        onScrollListener = new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {

                switch (scrollState) {
                    case AbsListView.OnScrollListener.SCROLL_STATE_FLING:
                        break;

                    case AbsListView.OnScrollListener.SCROLL_STATE_IDLE:
                        //滑動停止自動播放視頻
                        autoPlayVideo(view);
                        break;

                    case AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL:
                        break;
                }
            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                if (firstVisible == firstVisibleItem) {
                    return;
                }

                firstVisible = firstVisibleItem;
                visibleCount = visibleItemCount;
            }
        };

        listView.setOnScrollListener(onScrollListener);
    }

    /**
     * 滑動停止自動播放視頻
     */
    private void autoPlayVideo(AbsListView view) {

        for (int i = 0; i < visibleCount; i++) {
            if (view != null && view.getChildAt(i) != null && view.getChildAt(i).findViewById(R.id.player_list_video) != null) {
                currPlayer = (JCVideoPlayerStandard) view.getChildAt(i).findViewById(R.id.player_list_video);
                Rect rect = new Rect();
                //獲取當前view 的 位置
                currPlayer.getLocalVisibleRect(rect);
                int videoheight = currPlayer.getHeight();
                if (rect.top == 0 && rect.bottom == videoheight) {
                    if (currPlayer.currentState == JCVideoPlayer.CURRENT_STATE_NORMAL
                            || currPlayer.currentState == JCVideoPlayer.CURRENT_STATE_ERROR) {
                        currPlayer.startButton.performClick();
                    }
                    return;
                }
            }
        }
        //釋放其他視頻資源
        JCVideoPlayer.releaseAllVideos();
    }

    @Override
    public void onBackPressed() {
        if (JCVideoPlayer.backPress()) {
            return;
        }
        super.onBackPressed();
    }

    @Override
    protected void onPause() {
        super.onPause();
        JCVideoPlayer.releaseAllVideos();
    }
}

在我們滑動的時候，jiecaovideoplayer會自動停止正在播放的視頻，這裏面我還添加了一個功能，就是監聽當滑動停止的時候自動播放下一個視頻
2、VideoAdapter.java

package la.trytry.jiecaovideoplayer;

import android.content.Context;

import com.bumptech.glide.Glide;
import com.zhy.adapter.abslistview.CommonAdapter;
import com.zhy.adapter.abslistview.ViewHolder;

import java.util.List;

import fm.jiecao.jcvideoplayer_lib.JCVideoPlayer;
import fm.jiecao.jcvideoplayer_lib.JCVideoPlayerStandard;

/**
 * @author: lijuan
 * @description: 適配器
 * @date: 2016-12-04
 * @time: 17:04
 */
public class VideoAdapter extends CommonAdapter<String> {
    private Context mContext;

    public VideoAdapter(Context context, List<String> datas, int layoutId) {
        super(context, layoutId, datas);
        this.mContext = context;
    }

    @Override
    protected void convert(ViewHolder viewHolder, String url, int position) {
        JCVideoPlayerStandard player = viewHolder.getView(R.id.player_list_video);
        if (player != null) {
            player.release();
        }
        boolean setUp = player.setUp(url, JCVideoPlayer.SCREEN_LAYOUT_LIST, "");
        if (setUp) {
            Glide.with(mContext).load("http://a4.att.hudong.com/05/71/01300000057455120185716259013.jpg").into(player.thumbImageView);
        }
    }
}

這裏的適配器，我繼承了鴻洋大神寫的萬能的Adapter，所以我們還需添加這個庫的引用

compile 'com.zhy:base-adapter:3.0.3'

下面我們看看最終的效果

好了，本篇文章已經全部寫完但是當在fragment中加載視屏時無法全屏播放，不知道爲啥
