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);
}
}
属性atts.xml
复制代码 代码如下:
<declare-styleable name="TimeTextView"> </declare-styleable>
Adapter调用代码：
复制代码 代码如下:

}layout使用代码
