一、项目结构：主要app和player

app结构

二、增加遥控器按键选台

修改LivePlayActivity.java

1、声明变量

    public String channelId = "";
    public Timer timer = new Timer();
    public Toast mToast;

2、定义方法

    private void  mToastShow(String s){
        mToast = Toast.makeText(LivePlayActivity.this, "", Toast.LENGTH_SHORT );
        mToast.setText(s);
        LinearLayout layout = (LinearLayout) mToast.getView();
        TextView tv = (TextView) layout.getChildAt(0);
        tv.setTextSize(86);
        mToast.setGravity(Gravity.CENTER, 0, 0);
        mToast.show();
    }
   private Handler handler = new Handler(){
        @Override
        public void handleMessage(Message msg){
            switch (msg.what) {
                case 1:
                    mToastShow(String.valueOf(msg.obj));
                     break;
                case 2:
                    playChannel(0,Integer.parseInt(String.valueOf(msg.obj))-1,false);
                    break;

            }
            super.handleMessage(msg);
        }
    };

3、修改方法public boolean dispatchKeyEvent(KeyEvent event)

switch (keyCode) {}中增加如下代码：

                    default:
                        if(keyCode>=KeyEvent.KEYCODE_0 && keyCode<=KeyEvent.KEYCODE_9)
                        {
                            if(mToast != null)
                            {
                                mToast.cancel();
                            }
                            if(channelId=="") {
                                channelId +=keyCode-7;
                                mToastShow(channelId);
                                timer.schedule(new TimerTask() {
                                        @Override
                                        public void run() {
                                            Message message = new Message();
                                            message.what = 2;
                                            message.obj = channelId;
                                            handler.sendMessage(message);
                                            channelId ="";
                                        }
                                }, 2000);
                            }else {
                                channelId +=keyCode-7;
                                mToastShow(channelId);
                            }
                        }
                        break;

判断按键是0-9，

mToast.cancel();不显示

mToastShow(channelId);显示channelId

channelId为按键选择的频道号

timer计时器：2秒内的按键为选台数字，

4、比如遥控器连续按1和2，channelId为“12”，mToastShow显示数字12，timer.schedule以handler方式发送消息，handler.sendMessage(message)发送后，handleMessage方法调用playChannel()播放指定频道。

三、playChannel(）方法参数

playChannel(0,Integer.parseInt(String.valueOf(msg.obj))-1,false);

第1个参数：频道分组序号，从0开始

第2个参数：频道在分组中的序号，从0开始

第3个参数：改变播放源，默认false

三、播放源json格式

lives为直播源，group为分组，channels为频道列表。全部为json数组型

{

"lives": [{"group": "分组1","channels": [

{"name":"CCTV1","urls":["url1","url2"]},

{"name":"CCTV2","urls":["url3","url4"]},

...

]},{"group": "分组2","channels": [...]}],

ijk解码 ，建议app设置中，选用硬解码
