I am attempting to create a ToDo list for a class that I am in, and how I have the app is that I have an EditText on top to enter an item in the TDL. and then I am using an extended tablelayout to display the items. I also have a button that calls to a second activity that then has 2 other buttons to get the time and date to (hopefully) display on the TDL item after I hit the Done button on the button (where I would like to go back to the main activity) So far I am testing this on an AVD.
So what I think my issue is that I dont think my second activity is passing back the info that I want. According to the debugger, the onActivityResults method from the first one gets called earlier than the second activity gets called.
Here is the first Activity:
package com.parrishb.todo;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.view.KeyEvent;
import android.view.View;
import android.widget.EditText;
import android.widget.Button;
public class ToDoActivity extends Activity {
SharedPreferences pref;
public final static int ACTIVITY =1;
public static Globals g;
public ToDoView tdv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_to_do);
final EditText myEditText = (EditText)findViewById(R.id.myEditText);
Button mPickDate = (Button) findViewById(R.id.pickDate);
tdv = (ToDoView)findViewById(R.id.tdv);
myEditText.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if(event.getAction()== KeyEvent.ACTION_DOWN){
if((keyCode == KeyEvent.KEYCODE_DPAD_CENTER) || (keyCode == KeyEvent.KEYCODE_ENTER)){
tdv.addRow(ToDoActivity.this, myEditText.getText().toString());
myEditText.setText("");
return true;
}
}
return false;
}
});
// CLick listener for the date/time button
mPickDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivityForResult(new Intent(ToDoActivity.this, DatePickerActivity.class), ACTIVITY);
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if(resultCode== RESULT_OK && requestCode== ACTIVITY){
String append= (new StringBuilder().append(data.getStringExtra("Time"))
.append(" ").append(data.getStringExtra("Date")).toString());
tdv.editRow(ToDoActivity.this, append);
}
}
}
Here is my second activity:
package com.parrishb.todo;
import java.util.Calendar;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.TimePicker;
public class DatePickerActivity extends Activity {
private TextView mDateDisplay;
private Button mPickDate;
private int mYear;
private int mMonth;
private int mDay;
private TextView mTimeDisplay;
private Button mPickTime;
private Button done;
private int mhour;
private int mminute;
static final int TIME_DIALOG_ID = 1;
static final int DATE_DIALOG_ID = 0;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.buttonclick);
mDateDisplay =(TextView)findViewById(R.id.date);
mPickDate =(Button)findViewById(R.id.datepicker);
mTimeDisplay = (TextView) findViewById(R.id.time);
mPickTime = (Button) findViewById(R.id.timepicker);
done = (Button)findViewById(R.id.done);
//Pick time's click event listener
mPickTime.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
showDialog(TIME_DIALOG_ID);
}
});
//PickDate's click event listener
mPickDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(DATE_DIALOG_ID);
}
});
done.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//DatePickerActivity.this.finishActivityFromChild(DatePickerActivity.this, ToDoActivity.ACTIVITY);
//finishActivity(ToDoActivity.ACTIVITY);
//return;
//DatePickerActivity.this.finish(ToDoActivity.ACTIVITY);
//finish();
DatePickerActivity.this.finish();
}
});
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
mhour = c.get(Calendar.HOUR_OF_DAY);
mminute = c.get(Calendar.MINUTE);
}
@Override
public void finish(){
Intent resultIntent = new Intent();
Bundle b = new Bundle();
b.putString("Date", mDateDisplay.getText().toString());
b.putString("Time", mTimeDisplay.getText().toString());
resultIntent.putExtras(b);
setResult(Activity.RESULT_OK, resultIntent);
super.finish();
}
//-------------------------------------------update date----------------------------------------//
private void updateDate() {
mDateDisplay.setText(
new StringBuilder()
// Month is 0 based so add 1
.append(mMonth + 1).append("/")
.append(mDay).append("/")
.append(mYear).append(" "));
}
//-------------------------------------------update time----------------------------------------//
public void updatetime()
{
mTimeDisplay.setText(
new StringBuilder()
.append(pad(mhour)).append(":")
.append(pad(mminute)));
}
private static String pad(int c) {
if (c >= 10)
return String.valueOf(c);
else
return "0" + String.valueOf(c);
}
//Datepicker dialog generation
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDate();
}
};
// Timepicker dialog generation
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
mhour = hourOfDay;
mminute = minute;
updatetime();
}
};
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this,
mDateSetListener,
mYear, mMonth, mDay);
case TIME_DIALOG_ID:
return new TimePickerDialog(this,
mTimeSetListener, mhour, mminute, true);
}
return null;
}
}
I had scratched the second activity and brought the date and time picker into the main activity.
