android 自定义视频播放器之2/1

很久没更新博客，相信大家年后都比较忙。
今天给大家带来了一款视频播放器，首先确认的得有几点。
1、首先得有个播放视频的view；
2、加点额外功能进去左边上下滑动调节亮度，右边上下滑动调节声量；
3、视频当然得有快进和快退，左右滑动快进和快退；
4、可全屏播放；
5、暂时只做了离线播放。下篇博客再去研究在线播放。视频路径 这是视频本地路径，视频资源的话你们自己去找，文件夹会自动创建，放在该文件夹下面就可以了
private String Path = Environment.getExternalStorageDirectory() + “/wywVideo/

首先先贴上效果图：

咱们根据效果图一步一步的来，先进行布局：

该布局的图为
在这里咱们先把显示亮度和声音的布局隐藏掉，当需要的时候在显示出来。

现在则需要自定义一个可全屏播放的自定义VideoView出来代码如下：

package com.wyw.activity;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

public class FullVideoView extends VideoView {

    public FullVideoView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        // TODO Auto-generated constructor stub
    }
    public FullVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }
    public FullVideoView(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
    }

    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int width = getDefaultSize(0, widthMeasureSpec);
        int height = getDefaultSize(0, heightMeasureSpec);
        setMeasuredDimension(width, height);
    };
}

好，现在呢关键的部分来了。
首先呢得有滑动根据手势来区分和调节音量还是亮度或者是快进快退。
然后根据大小动态显示各自的进度条。然后呢在抬起手势中该隐藏的隐藏该初始化的初始化。播放时间呢我是用了一个延时线程，1000毫秒执行一次也就是1秒执行一次，正在播放长度大于视频总长度的话呢我就会吧当前线程给干掉。这样就达到了时间1秒1跳的效果。我们还需要把视频长度转换成时间。
好了，说了这么多应该也差不多能明白大概意思了，该动真家伙了。

方便一些朋友写，我这里也把适配器和数据集的代码也贴进来。
首先是数据（bean）：

package com.wyw.activity;

import android.graphics.Bitmap;

public class VideoListBean{

    /** 视频id */
    private String Video_Id;
    /** 视频名字 */
    private String Video_name;
    /** 视频路径 */
    private String Video_path;
    /** 视频展示配置表-封面图URL */
    private Bitmap Video_imgbg;
    /** 创建时间 */
    private String Create_time;



    public Bitmap getVideo_imgbg() {
        return Video_imgbg;
    }

    public void setVideo_imgbg(Bitmap video_imgbg) {
        Video_imgbg = video_imgbg;
    }

    public String getCreate_time() {
        return Create_time;
    }

    public void setCreate_time(String create_time) {
        Create_time = create_time;
    }

    public String getVideo_Id() {
        return Video_Id;
    }

    public void setVideo_Id(String video_Id) {
        Video_Id = video_Id;
    }

    public String getVideo_name() {
        return Video_name;
    }

    public void setVideo_name(String video_name) {
        Video_name = video_name;
    }

    public String getVideo_path() {
        return Video_path;
    }

    public void setVideo_path(String video_path) {
        Video_path = video_path;
    }

}

适配器：

package com.wyw.activity;

import android.view.LayoutInflater;

public class VideoListAdapter extends BaseAdapter {

    private Context context;

    private ArrayList<VideoListBean> list;

    public VideoListAdapter(Context context,ArrayList<VideoListBean> list){
        this.context=context;
        this.list=list;
    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @SuppressLint("InflateParams")
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        final ViewHolder viewHolder;
        final VideoListBean bean = list.get(position);
        if (convertView==null) {
            viewHolder = new ViewHolder();
            convertView = LayoutInflater.from(context).inflate(R.layout.item_video_listview, null);
            viewHolder.img_video = (ImageView) convertView.findViewById(R.id.item_video_img);
            viewHolder.txt_name = (TextView) convertView.findViewById(R.id.item_video_txt_name);
            viewHolder.txt_time = (TextView) convertView.findViewById(R.id.item_video_txt_time);
            convertView.setTag(viewHolder);
        }else{
            viewHolder = (ViewHolder) convertView.getTag();
        }

        viewHolder.txt_name.setText(bean.getVideo_name());
        viewHolder.img_video.setImageBitmap(bean.getVideo_imgbg());

        viewHolder.txt_time.setText(DateUtils.getDay());        

        return convertView;
    }


    private class ViewHolder{
        /**视频图片*/
        private ImageView img_video;
        /**视频名字*/
        private TextView txt_name;
        /**视频时间*/
        private TextView txt_time;
    }

}

隐藏各个控件我觉得应该要有动画才好看，这个就交给你们延伸了。下次呢我会加上动画以及研究下在线播放解码之类的。
希望大家多多关注我的博客，多多支持我。
