Answer 1

if you want to generate a toast which is displaying current time on a button click then use this code.

bt.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            Calendar c = Calendar.getInstance();
            hour = c.get(Calendar.HOUR_OF_DAY);
            min = c.get(Calendar.MINUTE);
            int ds = c.get(Calendar.AM_PM);
            if(ds==0)
            AM_PM="pm";
            else
            AM_PM="am";

            Toast.makeText(MainActivity.this, ""+hour+":"+min+AM_PM, Toast.LENGTH_SHORT).show();


        }
    });

Answer 3

Below solution might help -

final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);

updateDisplay();

private void updateDisplay() {
    mDateDisplay.setText(
        new StringBuilder()
        // Month is 0 based so add 1
        .append(mMonth + 1).append("-")
        .append(mDay).append("-")
        .append(mYear).append(" "));
}

Answer 4

    TextView tv = (TextView) findViewById(R.id.textView1);
    SimpleDateFormat dfDate_day= new SimpleDateFormat("E, dd/MM/yyyy HH:mm:ss");
    String dt="";
    Calendar c = Calendar.getInstance(); 
    data=dfDate_day.format(c.getTime());
    tv.setText(dt);

Answer 5

I suggest:

long date = System.currentTimeMillis(); 

SimpleDateFormat sdf = new SimpleDateFormat("MMM MM dd, yyyy h:mm a");
String dateString = sdf.format(date);   
tvDisplayDate.setText(dateString);

which displays in the following example format

You can use whatever format you want - options can be found at Oracle

Answer 6

note*:

import java.text.DateFormat;
import java.util.Date;

// Donot import "import java.sql.Date;"

TextView tv = (TextView) findViewById(R.id.textView1);
String ct = DateFormat.getDateInstance().format(new Date());
tv.setText(ct);
