Run Code Over And Over

In my application I am showing a clock in a TextView, and I want to update it in real time. I tried to run it like this: public void clock() { while(clock_on == true) {

Solution 1:

Please Try:

privateHandlerhandler=newHandler();
runnable.run();

privateRunnablerunnable=newRunnable() 
{

publicvoidrun() 
{
     //// Do the stuff//if(clock_on == true) {

             executeClock();

     }

     handler.postDelayed(this, 1000);
}
};

Solution 2:

Use a Handler:

privateHandlerhandler=newHandler() {

    @OverridepublicvoidhandleMessage(android.os.Message msg) {
            TextViewtimeTv= (TextView) findViewById(R.id.time);
            long currentTime=System.currentTimeMillis();
            Calendar cal=Calendar.getInstance();
            cal.setTimeInMillis(currentTime);
            String showTime=String.format("%1$tI:%1$tM %1$Tp",cal);
            timeTv.setText(showTime);

            handler.sendEmptyMessageDelayed(0, 1000);
    }
};
