思路分析：（这个自定义控件很简单）

1、自定义一个View集成TextView

2、子线程的开启和停止

3、倒计时的计算

View的代码：

package view;import android.content.Context;import android.util.AttributeSet;import android.util.Log;import android.view.View;import android.widget.TextView;/** * Created by Ricky on 2016/10/11. */public class TimerTextView extends TextView implements Runnable{    private boolean isRun = false;    private long secondCount = 60;    public TimerTextView(Context context, AttributeSet attrs) {        super(context, attrs);        this.setFocusable(true);        this.setClickable(true);        this.setOnClickListener(new OnClickListener() {            @Override            public void onClick(View view) {                if(!isRun){                    beginRun();                }            }        });    }    @Override    public void run() {        if(isRun){            Log.v("aa:","********************************** > " + Thread.currentThread().getName());            this.setText(ComputeTime());            postDelayed(this, 1000);        }else {            removeCallbacks(this);        }    }    /**     * 倒计时计算     */    private String ComputeTime() {        String backTime = "";        secondCount--;        if (secondCount <= 0) {            backTime = "重新获取";            secondCount = 60;            this.isRun = false;            this.setFocusable(true);            this.setClickable(true);        }else{            backTime = secondCount + "秒";        }        return backTime;    }    public void setSecondCount(long secondCount){        this.secondCount = secondCount;    }    public boolean isRun() {        return isRun;    }    public void beginRun() {        this.isRun = true;        this.setFocusable(false);        this.setClickable(false);        run();    }    public void stopRun(){        this.isRun = false;    }}
