[mediatek]修改google原生桌面的时钟显示格式

通过keyguardstatusview.java中可以看到，代码所采用的日期格式固定

观察者定义如下：

private static class FormatChangeObserver extends ContentObserver {

private WeakReference<ClockView> mClock;

private Context mContext;

public FormatChangeObserver(ClockView clock) {

super(new Handler());

mClock = new WeakReference<ClockView>(clock);

mContext = clock.getContext();

}

@Override

public void onChange(boolean selfChange) {

ClockView digitalClock = mClock.get();

if (digitalClock != null) {

digitalClock.setDateFormat();

digitalClock.updateTime();

} else {

try {

mContext.getContentResolver().unregisterContentObserver(this);

} catch (RuntimeException e) {

// Shouldn‘t happen

}

}

}

}
