这个要求用的不多,但是也有写项目上面不想看手机时间,要求你直接把时间日期给动态显示在界面上 这里就记录一个自定义控件吧
public class UpdateTimeTextView extends AppCompatTextView {private String TAG = "UpdateTimeTextView";private Thread runnable;private boolean mBoolean = true;Handler handler = new Handler() {@Overridepublic void handleMessage(Message msg) {UpdateTimeTextView.this.setText((String) msg.obj);}};private String DEFAULT_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss ";public UpdateTimeTextView(Context context) {super(context);Log.e(TAG, "UpdateTimeTextView: 1");}public UpdateTimeTextView(Context context, AttributeSet attrs) {super(context, attrs);init();//加载方法Log.e(TAG, "UpdateTimeTextView: 2");}public UpdateTimeTextView(Context context, AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);Log.e(TAG, "UpdateTimeTextView: 3");}@Overrideprotected void onDetachedFromWindow() {super.onDetachedFromWindow();mBoolean = false;Log.e(TAG, "onDetachedFromWindow:关闭循环 ");}/*** 更新时间*/private void init() {runnable = new Thread() {@Overridepublic void run() {while (mBoolean) {Calendar mCalendar = Calendar.getInstance();SimpleDateFormat dateFormatter = new SimpleDateFormat(DEFAULT_TIME_FORMAT);String time = dateFormatter.format(Calendar.getInstance().getTime());//获取当前时间String mWay = String.valueOf(mCalendar.get(Calendar.DAY_OF_WEEK));//获取星期if ("1".equals(mWay)) {mWay = "天";} else if ("2".equals(mWay)) {mWay = "一";} else if ("3".equals(mWay)) {mWay = "二";} else if ("4".equals(mWay)) {mWay = "三";} else if ("5".equals(mWay)) {mWay = "四";} else if ("6".equals(mWay)) {mWay = "五";} else if ("7".equals(mWay)) {mWay = "六";}String tiems = time + "星期" + mWay;Log.e(TAG, "run: " + time + "1231231");handler.sendMessage(handler.obtainMessage(100, tiems));try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}}};runnable.start();}//根据毫秒时间获取格式化的提示 按自己实际要求来写private String convertTimeToFormat(long timeMills) {long curTime = Calendar.getInstance().getTimeInMillis();long time = (curTime - timeMills) / (long) 1000;//已经将单位转换成秒if (time > 0 && time < 60) {return "刚刚";} else if (time >= 60 && time < 3600) {return time / 60 + "分钟前";} else if (time >= 3600 && time < 3600 * 24) {return time / 3600 + "小时前";} else if (time >= 3600 * 24 && time < 3600 * 24 * 30) {return time / 3600 / 24 + "天前";} else if (time >= 3600 * 24 * 30 && time < 3600 * 24 * 30 * 12) {return time / 3600 / 24 / 30 + "个月前";} else if (time >= 3600 * 24 * 30 * 12) {return time / 3600 / 24 / 30 / 12 + "年前";} else {return "刚刚";}}}
效果图就看下面
我这个是直接截图静态的,有需要的话可以自己直接开个程序跑一下就知道了
布局的话
<com.ewininfo.testproject.UpdateTimeTextViewandroid:id="@+id/up_time"android:layout_width="0dp"android:layout_height="50dp"android:layout_weight="1"android:gravity="center"android:text=""android:textSize="25sp"android:textStyle="bold"/>
直接这样一个就行了 界面上不需要操作 会自动刷新
