一.简单的思路为：生产者+消费者模式来实现
1.重写这个对象的触摸事件（对触摸事件与事件分发机制的同学不了解的可以查阅其他资料）
2.在MotionEvent.ACTION_DOWN:事件中启动一个线程，这个线程类似生产者，它不停的生产想要的事件
这里的事件为了调用的顺序，建议采用队列的方式来缓存，事件对象可任意
3.在MptionEvent.ACTION_UP:事件中取消这个线程，取消线程即停止这个线程，采用置中断标记来停止一个线程
5.从任务队列中取出任务进行执行，类似消费者，代码模式与生产者很类似，具体的思路可参看我的前几编文章，里面有很详细的生产者消费者模式多线程的运用
二.任务请求对象：
package com.example.baize.touchdelegate.producer;
import java.util.LinkedList;
/**
* 事件对象
* <p>
* Created by lxb on 2017/3/31.
*/
public class EventRequest<T> {
private LinkedList<T> requestQueue = new LinkedList<>();
private int count; // 任务队列请求数
public EventRequest() {
this.count = 0;
}
public synchronized void buildEvent(T request) throws InterruptedException {
while (!requestQueue.isEmpty() && count >= requestQueue.size()) {
wait();
}
System.out.println(Thread.currentThread().getName() + "正在产生" + request + "到请求队列中");
requestQueue.addLast(request);
count++;
notifyAll();
}
public synchronized T sendEvent() throws InterruptedException {
while (count <= 0) {
wait();
}
T request = requestQueue.pop();
count--;
notifyAll();
System.out.println(Thread.currentThread().getName() + "已经成功从请求队列中拿到" + request);
return request;
}
}
三.生产者线程：
package com.example.baize.touchdelegate.producer;
/**
* 生产游戏手柄的按键事件,本线程通过打断与启动标志来停止线程
* <p>
* Created by lxb on 2017/3/31.
*/
public class ProduceEventThread<T> extends Thread {
private EventRequest<T> eventRequest;
private volatile boolean terminated = false; // 停止请求标志
private T type; //事件请求类型
public ProduceEventThread(T type, EventRequest<T> eventRequest) {
this.eventRequest = eventRequest;
this.type = type;
}
public void run() {
while (!terminated) {
try {
this.eventRequest.buildEvent(type);
} catch (InterruptedException e) {
terminated = true;
}
}
}
public void cancel(){
terminated = true;
interrupt();
}
}
四.消费者线程：
package com.example.baize.touchdelegate.producer;
/**
* 发送游戏手柄事件的线程，类似消费者
*
* Created by lxb on 2017/3/31.
*/
public class SendEventThread<T> extends Thread {
private EventRequest<T> eventRequest;
private volatile boolean terminated = false; // 停止请求标志
private T type; //事件请求类型
public SendEventThread(T type, EventRequest<T> eventRequest) {
this.eventRequest = eventRequest;
this.type = type;
}
public void run() {
while (!terminated) {
try {
this.eventRequest.sendEvent();
} catch (InterruptedException e) {
terminated = true;
}
}
}
public void cancel(){
terminated = true;
interrupt();
}
}
五。整个触摸对象的触摸事件代理类：
package com.example.baize.touchdelegate;
import android.view.MotionEvent;
import android.view.View;
import com.example.baize.touchdelegate.producer.EventRequest;
import com.example.baize.touchdelegate.producer.ProduceEventThread;
import com.example.baize.touchdelegate.producer.SendEventThread;
/**
* 游戏手柄按键不停的产生事件，由此类进行代理并采用生产者消费者模式实现
* <p>
* Created by lxb on 2017/3/31.
*/
public class TouchEventDelegate<T> implements View.OnTouchListener {
private T type ;
private ProduceEventThread<T> produceEventThread;
private SendEventThread<T> sendEventThread;
private EventRequest<T> eventRequest;
public TouchEventDelegate(T type) {
this.type = type;
eventRequest = new EventRequest<>();
}
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
startThreads();
break;
case MotionEvent.ACTION_MOVE:
break;
case MotionEvent.ACTION_UP:
stopAllThreads();
break;
}
return true;
}
private void startThreads() {
produceEventThread = new ProduceEventThread<>(type, eventRequest);
sendEventThread = new SendEventThread<>(type, eventRequest);
produceEventThread.start();
sendEventThread.start();
}
private void stopAllThreads() {
if (produceEventThread != null) {
produceEventThread.cancel();
produceEventThread = null;
}
if (sendEventThread != null) {
sendEventThread.cancel();
sendEventThread = null;
}
}
}
