效果圖如下所示：
由于我仿的京東是分模塊的,所以,這次主要描述秒殺模塊!
首先設(shè)置好時(shí)間的背景
drawable文件下創(chuàng)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,你可以單獨(dú)書寫,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="京東秒殺" 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點(diǎn)場(chǎng)" 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>
這里寫邏輯代碼
//使用handler用于更新UIprivate Handler handler = new Handler() { @Override public void handleMessage(Message msg) { super.handleMessage(msg); countDown(); sendEmptyMessageDelayed(0, 1000); } }; /** * 秒殺 */ 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 + "點(diǎn)場(chǎng)"); buffer.append((hour + 2)); buffer.append(":00:00"); } else { mMiaoshaTimeTv.setText((hour - 1) + "點(diǎn)場(chǎng)"); 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,這里才是開(kāi)啟的代碼
private void startCountDown() { handler.sendEmptyMessage(0); }總結(jié)
以上所述是小編給大家介紹的Android 仿京東秒殺倒計(jì)時(shí)代碼 ，希望對(duì)大家有所幫助，如果大家有任何疑問(wèn)請(qǐng)給我留言，小編會(huì)及時(shí)回復(fù)大家的。在此也非常感謝大家對(duì)武林網(wǎng)網(wǎng)站的支持！
