自定义Task工具，调用系统的IdleHandler方法

1、工具类，调用系统的IdleHandler方法

package com.abbi.viewdemo;

import android.os.Looper;

import android.os.MessageQueue;

import java.util.LinkedList;

import java.util.Queue;

public class DelayTaskDispatcher {

private Queue<Task> delayTasks = new LinkedList<>();

private MessageQueue.IdleHandler idleHandler = new MessageQueue.IdleHandler() {

@Override

public boolean queueIdle() {

if(delayTasks.size() > 0){

Task task = delayTasks.poll();

if(task != null){

task.run();

}

}

return !delayTasks.isEmpty();

}

};

public DelayTaskDispatcher addTask(Task task){

delayTasks.add(task);

return this;

}

public void start() {

Looper.myQueue().addIdleHandler(idleHandler);

}

}

2、activity 处调用：

@Override

protected void onCreate(Bundle savedInstanceState){

super.onCreate(savedInstanceState);

InjectManager.inject(this);

mBtn.setText(app_name);

mBtn.setBackgroundColor(color);

mBtn.post(new Runnable() {//其他方法获取线程处理事务，不能太耗时

@Override

public void run() {

}

});

Looper.myQueue().addIdleHandler(new MessageQueue.IdleHandler() {

@Override

public boolean queueIdle() {

return false;

}

});

new DelayTaskDispatcher().addTask(new Task() {

@Override

public void run() {

Log.d("abbi", "DelayTaskDispatcher 1 run");

}

}).addTask(new Task() {

@Override

public void run() {

Log.d("abbi", "DelayTaskDispatcher 2 run");

}

}).start();

}
