[android help] Closing Soft Keyboard on Home Button Press


So I have an app with a custom AlertDialog that has an Ok and Cancel button, and an EditText Object. When I click on the 'Name of Workout' button, the AlertDialog and the soft Keyboard open. At this point, with the AlertDialog open and the soft Keyboard displayed, if the user decides to hit the home key, the app closes, but the soft keyboard is still displayed. How would I close the soft Keyboard along with the entire app from this point? Here is my code:



package com.example.test_project;

import java.util.Calendar;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.TimePickerDialog;

import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;

import android.view.inputmethod.InputMethodManager;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.TimePicker;

public class NewWorkout extends Activity {
/** Called when the activity is first created. */

private TextView mDateDisplay;
private Button mPickDate;
private int mYear;
private int mMonth;
private int mDay;

private TextView mTimeDisplay;
private Button mTimePicker1;
private int hour;
private int minute;
private String zone;

static final int DATE_DIALOG_ID = 0;
static final int TIME_DIALOG_ID = 99;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_new_workout);
    final InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

    // capture our View elements
    mDateDisplay = (TextView) findViewById(R.id.dateOfWorkoutTextView);
    mPickDate = (Button) findViewById(R.id.dateOfWorkoutButton);
    mTimeDisplay = (TextView) findViewById(R.id.timeOfWorkoutTextView);
    mTimePicker1 = (Button) findViewById(R.id.timeOfWorkoutButton);


    // add a click listener to the button
    mPickDate.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            showDialog(DATE_DIALOG_ID);
        }
    });

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

    final Calendar t = Calendar.getInstance();
    hour = t.get(Calendar.HOUR_OF_DAY);
    minute = t.get(Calendar.MINUTE);

    //set the current time into the textview



    mTimePicker1.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            showDialog(TIME_DIALOG_ID);
        }
    });

}

// updates the date in the TextView
private void updateDisplay() {
        StringBuilder string1 = new StringBuilder()
                // Month is 0 based so add 1
                .append(mMonth + 1).append("-")
                .append(mDay).append("-")
                .append(mYear).append(" ");
    mDateDisplay.setText(string1);
}

// the callback received when the user "sets" the date in the dialog
private DatePickerDialog.OnDateSetListener mDateSetListener =
        new DatePickerDialog.OnDateSetListener() {

            public void onDateSet(DatePicker view, int year,
                                  int monthOfYear, int dayOfMonth) {
                mYear = year;
                mMonth = monthOfYear;
                mDay = dayOfMonth;
                updateDisplay();
            }
        };

         new TimePickerDialog.OnTimeSetListener() {
     public void onTimeSet(TimePicker view, int selectedHour, int selectedMinute) {
         hour = selectedHour;
         minute = selectedMinute;
         updateTimeDisplay();
     }
 };

//set current time into textView
private void updateTimeDisplay() {
     if(hour > 12){
         hour -= 12;
         zone = "PM";
     }
     else
         zone = "AM";

     if(minute >= 10){
     mTimeDisplay.setText(new StringBuilder().append(hour)
                .append(":").append(minute).append(" ").append(zone));
     }
     else
         mTimeDisplay.setText(new StringBuilder().append(hour)

@Override

    case TIME_DIALOG_ID:
        return new TimePickerDialog(this, timePickerListener, hour, minute, false);
    }
    return null;
}


public void nameOfWorkout(View view){
    AlertDialog.Builder alert = new AlertDialog.Builder(this);

    alert.setTitle("Enter a Name for This Workout");

    // Set an EditText view to get user input 
    final EditText input = new EditText(this);
    alert.setView(input);
    // Prepping the soft keyboard to open with the AlertDialog
    final InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); 
    imm.hideSoftInputFromWindow(input.getWindowToken(), 0);

    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int whichButton) {
      String value = input.getText().toString();
      TextView edit = (TextView) findViewById(R.id.nameOfWorkoutTextView);
      edit.setText(value);
      imm.toggleSoftInput(InputMethodManager.RESULT_HIDDEN, 0);
      }
    });

    alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface dialog, int whichButton) {
          imm.toggleSoftInput(InputMethodManager.RESULT_HIDDEN, 0);
      }
    });
        //alert.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    alert.show();

    //Causing the soft keyboard to open with the AlertDialog
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

}


Thanks!
