android自定义倒计时控件示例1

自定义TextView控件TimeTextView代码：

复制代码代码如下:

import android.content.Context;

import android.content.res.TypedArray;

import android.graphics.Paint;

import android.text.Html;

import android.util.AttributeSet;

import android.widget.TextView;

import com.new0315.R;

/**

* @author Administrator

public class TimeTextView extends TextView implements Runnable{

Paint mPaint; //画笔,包含了画几何图形、文本等的样式和颜色信息

private long[] times;

private long mday, mhour, mmin, msecond;//天，小时，分钟，秒

private boolean run=false; //是否启动了

public TimeTextView(Context context, AttributeSet attrs) {

super(context, attrs);

mPaint=new Paint();

TypedArray array = context.obtainStyledAttributes(attrs, R.styleable.TimeTextView);

array.recycle(); //一定要调用，否则这次的设定会对下次的使用造成影响

}

public TimeTextView(Context context, AttributeSet attrs, int defStyle) {

super(context, attrs, defStyle);

mPaint=new Paint();

TypedArray array = context.obtainStyledAttributes(attrs, R.styleable.TimeTextView);

array.recycle(); //一定要调用，否则这次的设定会对下次的使用造成影响

}

public TimeTextView(Context context) {

super(context);

}

public long[] getTimes() {

return times;

}

public void setTimes(long[] times) {

this.times = times;

mday = times[0];

mhour = times[1];

mmin = times[2];

msecond = times[3];

}

/**

* 倒计时计算

private void ComputeTime() {

msecond--;

if (msecond < 0) {

mmin--;

msecond = 59;

if (mmin < 0) {

// 倒计时结束

}

public boolean isRun() {

}

public void setRun(boolean run) {

}

@Override

public void run() {

//标示已经启动

run=true;

ComputeTime();

String strTime="还剩</pre>

"+mday+"

"+mhour+"

"+

mmin+"

"+msecond+"

<pre>秒";

this.setText(Html.fromHtml(strTime));

postDelayed(this, 1000);
