Android自定义控件动态显示时间 年月日 时分秒

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() {
        @Override
        public 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");
    }

    @Override
    protected void onDetachedFromWindow() {
        super.onDetachedFromWindow();
        mBoolean = false;
        Log.e(TAG, "onDetachedFromWindow:关闭循环 ");
    }

    /**
     * 更新时间
     */
    private void init() {
        runnable = new Thread() {
            @Override
            public 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

直接这样一个就行了 界面上不需要操作 会自动刷新
