android自定义倒计时控件示例

这篇文章主要介绍了Android秒杀倒计时自定义TextView示例，大家参考使用吧



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;
/**
* 自定义倒计时文本控件
* @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) {
mmin = 59;
mhour--;
if (mhour < 0) {
// 倒计时结束
mhour = 59;
mday--;

}
}

}

}

public boolean isRun() {
return run;
}

public void setRun(boolean run) {
this.run = run;
}

@Override
public void run() {
//标示已经启动
run=true;

ComputeTime();

String strTime="还剩</pre>
<span style="color: red;">"+mday+"</span>
<pre>"+"天</pre>
<span style="color: red;">"+mhour+"</span>
<pre>小时</pre>
<span style="color: red;">"+
mmin+"</span>
<pre>分钟</pre>
<span style="color: red;">"+msecond+"</span>
<pre>秒";
this.setText(Html.fromHtml(strTime));

postDelayed(this, 1000);

}

}
