EditText和onFocusChangeListener

Question

1st of all I wanna thank you all for your great help. I'm a newby and stackoverflow answered most of my questions with already existing answers :-)

For my current project I want to create a kind of a calendar entry and the user has to set a date and time for this entry. I decided to have EditText and want to open the picker @OnFocus on EditText (I know about the discussions if this makes sense or not but I think it makes sense to do so).

I have two issues now:
1) I don't get the OnFocusListener to work :-(
2) The time picker is always am/pm format though in the EditText it writes 24h format. My device is set to 24h and I don't get the time picker to use 24h, dependent on the device settings. I know it can be set to always be 24h but I think this is confusing for other countries not using 24h so it should be device setting dependent.

I hope you can help me and fix my hopefully not so messy code. Thanks in advance!

Here's my code:

public class Test extends ActionBarActivity implements OnFocusChangeListener {

EditText editText, txtDate, txtTime;
Button button, btnDate;

// Variable for storing current date and time
private int mYear, mMonth, mDay, mHour, mMinute;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test);

    if (savedInstanceState == null) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.container, new  PlaceholderFragment()).commit();
    }

// Force keyboard to open as request focus doesn’t open keyboard
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

// Date & Time Picker Stuff
 txtDate = (EditText) findViewById(R.id.etDate);
    txtTime = (EditText) findViewById(R.id.etTime);

    txtDate.setOnFocusChangeListener(new OnFocusChangeListener());
    txtTime.setOnFocusChangeListener(new OnFocusChangeListener());

}

@Override
public void onFocusChange(View v, boolean hasFocus) {

    if (v == txtDate) {

        // Process to get Current Date
        final Calendar c = Calendar.getInstance();
        mYear = c.get(Calendar.YEAR);
        mMonth = c.get(Calendar.MONTH);
        mDay = c.get(Calendar.DAY_OF_MONTH);

        // Launch Date Picker Dialog
        DatePickerDialog dpd = new DatePickerDialog(this,
                new DatePickerDialog.OnDateSetListener() {

                    @Override
                    public void onDateSet(DatePicker view, int year,
                            int monthOfYear, int dayOfMonth) {
                        // Display Selected date in edit text
                        txtDate.setText(dayOfMonth + "-"
                                + (monthOfYear + 1) + "-" + year);

                    }
                }, mYear, mMonth, mDay);
        dpd.show();
    }
    if (v == txtTime) {

        // Process to get Current Time
        final Calendar c = Calendar.getInstance();
        mHour = c.get(Calendar.HOUR_OF_DAY);
        mMinute = c.get(Calendar.MINUTE);

        // Launch Time Picker Dialog
        TimePickerDialog tpd = new TimePickerDialog(this,
                new TimePickerDialog.OnTimeSetListener() {

                    @Override
                    public void onTimeSet(TimePicker view, int hourOfDay,
                            int minute) {
                        // Display Selected time in edit text
                        txtTime.setText(hourOfDay + ":" + minute);
                    }
                }, mHour, mMinute, false);
        tpd.show();
    }
 }

To fix focus listener issue:

Change setOnFocusChangeListener(new OnFocusChangeListener()); to setOnFocusChangeListener(this); to hook your EditTexts up to the method you defined.

A solution to 12 hour vs 24 hour display:

You can set the display to 24 hour if the system is set to 24 hour, or to 12 hour if the system is set to 12 hour formatting.

import android.text.format.DateFormat;

// ...

timePicker.setIs24HourView(DateFormat.is24HourFormat(ActionBarActivity.this))
