removeall views in this, it will call when u press the navigation back button

Alternatively, you can preserve AlertDialog instance through AlertDialog.Builder.create() instead of AlertDialog.Builder instance.
If you use custom view, dialog will be created and then the custom view will be attached to dialog window every time AlertDialog.Builder.show().

Can anyone help please? When click on the quiz button the application will close. I want it to go to quiz page which called HomeScreen.java

looks good to me, did u declare the second activity in the manifest file? :
<activity android:name="HomeScreen"/>
If that doesn't work, use some break points and the debugger, hope it helps.

PopUp Window not updating database - Android

I'm trying to create a kind of game using Android Studio. Till now I have done a gridview wich shows players stored in a database. I have had some problems with gridView.setOnItemClickListener, I have had to do it by putting the code into gridView's Adparter.class so if you know how I can do that into gridView's activity please tell me.
My problem now is that when you click on a player a popup window appears in which you could change the player's name or his genre. When you click on Confirm's button the database will automatically been updated, but it doesn't works. I have try to do it step by step by using Toast in order to know if it run that part or not, the problem could be the context, but maybe I'm crazy.
I left you some pics and the code related to it.

From what I´ve seen in your code is, that you try to get the id from an intent in your PopUp window class. You have made one thing wrong:
Intent i = getIntent();
i.getIntExtra("Id", id);
it must be:
Intent i = getIntent();
id = i.getIntExtra("Id", id); //forgott id = here
and you should give a default value to id for example id=-1 . The problem is, by updating your database, you give a non value integer and so it is not possible to update your table.

Using getFragmentManager on a ListActivity

I just want to know if this is possible since first. I have created a custom listView based on the tutorial I read from Sai Geetha. Well it works perfectly on my app except that it needs to extend ListActivity instead of FragmentActivity. Now I'm having a hard time configuring and adding a dialog for this since I need to apply a fragment dialog and I can't use the getFragmentManager() since I'm not working with the FragmentActivity. Is there's another way I can do to work on this without sacrificing the ListActivity? Thanks!
Here's my code so far

You can use ListFragment inside FragmentActivity instead of using a ListActivity.

TimePicker + CheckBox

I've got a TimePicker in my app and i want to add above it a CheckBox that if it checked the TimePicker won't work. This is my TimePicker: http://developer.android.com/guide/topics/ui/controls/pickers.html#TimePicker.
How can I do that? I want the timePicker to look the same as the example.

I will put here the entire project also for others to use it if they ever need it:

Here's an functional example with all your requirements.
Tested and 100% functional :)
Put this in xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
>
<TextView
android:id="#+id/timer_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Check this to Cancel Alarm"
android:layout_above="#+id/time_picker"
android:layout_toRightOf="#+id/time_picker_checkbox"
/>
<CheckBox
android:id="#+id/time_picker_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/time_picker"
/>
<TimePicker
android:id="#+id/time_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
/>
And Here is your java code:
package com.example.chxboxtest;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CheckBox;
import android.widget.TimePicker;
import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener {
private CheckBox cBox;
private TimePicker tPicker;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initButtons();
}
private void initButtons() {
tPicker = (TimePicker) findViewById(R.id.time_picker);
cBox = (CheckBox) findViewById(R.id.time_picker_checkbox);
cBox.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.time_picker_checkbox: {
if (((CheckBox) v).isChecked()) {
Toast.makeText(this, "Deactivate",Toast.LENGTH_SHORT).show();
tPicker.setEnabled(false);
} else {
Toast.makeText(this, "Activate",Toast.LENGTH_SHORT).show();
tPicker.setEnabled(true);
}
}
break;
default:
break;
}
}
}
If you want this example in a custom dialog please let me know.
Cheers,
