效果图如下所示：
由于我仿的京东是分模块的,所以,这次主要描述秒杀模块!
首先设置好时间的背景
drawable文件下创建shape_miaosha_time.xml
<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <solid android:color="#000"></solid> <corners android:radius="2.5dp"></corners> </shape>
然后主要布局,你可以单独书写,然后引用出去
**count_down.xml**
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFFFFF"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="40dp"
android:gravity="center_vertical">
<TextView
android:id="@+id/tv_miaosha"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:text="京东秒杀"
android:textColor="#f00"
android:textSize="20sp" />
<TextView
android:id="@+id/tv_miaosha_time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp"
android:text="12点场"
android:textSize="20sp" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="@+id/tv_miaosha_shi"
android:layout_width="25dp"
android:layout_height="25dp"
android:background="@drawable/shape_miaosha_time"
android:gravity="center"
android:text="1"
android:textColor="#fff"
android:textSize="15sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:text=":" />
<TextView
android:id="@+id/tv_miaosha_minter"
android:layout_width="25dp"
android:layout_height="25dp"
android:background="@drawable/shape_miaosha_time"
android:gravity="center"
android:text="1"
android:textColor="#fff"
android:textSize="15sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:text=":" />
<TextView
android:id="@+id/tv_miaosha_second"
android:layout_width="25dp"
android:layout_height="25dp"
android:background="@drawable/shape_miaosha_time"
android:gravity="center"
android:text="1"
android:textColor="#fff"
android:textSize="15sp" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
这里写逻辑代码
//使用handler用于更新UI
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
countDown();
sendEmptyMessageDelayed(0, 1000);
}
};
/**
* 秒杀
*/
private void countDown() {
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date curDate = new Date(System.currentTimeMillis());
String format = df.format(curDate);
StringBuffer buffer = new StringBuffer();
String substring = format.substring(0, 11);
buffer.append(substring);
Log.d("ccc", substring);
Calendar calendar = Calendar.getInstance();
int hour = calendar.get(Calendar.HOUR_OF_DAY);
if (hour % 2 == 0) {
mMiaoshaTimeTv.setText(hour + "点场");
buffer.append((hour + 2));
buffer.append(":00:00");
} else {
mMiaoshaTimeTv.setText((hour - 1) + "点场");
buffer.append((hour + 1));
buffer.append(":00:00");
}
String totime = buffer.toString();
try {
java.util.Date date = df.parse(totime);
java.util.Date date1 = df.parse(format);
long defferenttime = date.getTime() - date1.getTime();
long days = defferenttime / (1000 * 60 * 60 * 24);
long hours = (defferenttime - days * (1000 * 60 * 60 * 24)) / (1000 * 60 * 60);
long minute = (defferenttime - days * (1000 * 60 * 60 * 24) - hours * (1000 * 60 * 60)) / (1000 * 60);
long seconds = defferenttime % 60000;
long second = Math.round((float) seconds / 1000);
mMiaoshaShiTv.setText("0" + hours + "");
if (minute >= 10) {
mMiaoshaMinterTv.setText(minute + "");
} else {
mMiaoshaMinterTv.setText("0" + minute + "");
}
if (second >= 10) {
mMiaoshaSecondTv.setText(second + "");
} else {
mMiaoshaSecondTv.setText("0" + second + "");
}
} catch (ParseException e) {
e.printStackTrace();
}
}
注意,这里才是开启的代码
private void startCountDown() {
handler.sendEmptyMessage(0);
}
