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
