Test if a user has selected an item from AutoCompleteTextView

My problem is that my code does not react accordingly whenever an user selects an item from an AutoCompleteTextView.
flag is a variable which is set to a value whenever one item from each AutoCompleteTextView has been selected. If it's set to 1, then it means it's right and it should proceed to main activity. Otherwise, a toast is displayed on click of button whose onClick calls the method callMainActivity.
There are no errors. Gradle build is successful, but clicking on that button (mentioned above) does nothing at all.

//... your stuff
if(autocompleteView_area.getListSelection()>0) {
flag = 1;
System.out.println(flag + "flag at area");
}else
flag=0;
}
});
}
public void callMainActivity(View view){
if(flag==1) {
Intent in = new Intent(getBaseContext(), MainActivity.class);
startActivity(in);
}
else
Toast.makeText(getBaseContext(),"Please select all fields properly",Toast.LENGTH_LONG);
}
}

The reason you are not seeing the Toast or changing activities, is because you are never calling callMainActivity(View view) in your code. Add this line to the end of all your OnClickListeners: callMainActivity(arg0) -- if this does not work, put some log statements in your OnClickListeners to check if they are triggering or not.
Also, if you want to trigger the call when an item from your AutoCompleteTextView result list is selected, you should use an AdapterView.OnItemClickedListener instead. This will notify you when an item is selected from the AutoCompleteTextView list, or when nothing is selected and then you can react accordingly.

Problems with retaining user inputted form data when switching between activities

If anyone could help me with the following problem I would be eternally grateful.
My android app is a questionnaire to carry out property surveys. Each activity relates to an element of the property i.e. kitchen, bathroom, central heating etc. There will be circa 50 questions when the app is complete. Each activity has three Spinners and two Edit Texts with which the user must input data relating to the age and condition of the relevant element of the property before moving onto the next activity.
My problem is as follows:
Question 1 relates to the kitchen. Once all the relevant data is inputted I use an intent (via a 'next page' button) to start the next activity which relates to the bathroom. However, if I realise I made an error with my data input on the kitchen activity and go back via an intent from the bathroom activity (in the same way I got to the bathroom activity from the kitchen activity) the data I previously inputted is no longer there.
How do I retain this data? It is essential that my app users can flick backwards and forwards between the survey questions and view the data they have previously inputted. Once all 50 questions have been answered the data will be saved to a database and the next property can then be surveyed.
I have trawled the internet and various books for the answer to this but I am encountering conflicting information. Some say use on Pause, others say on Stop, others say on Saved Instance State. I'm confused?? I've been stuck on this for three days now so any help is very much appreciated.

Well you can use a number of different methods which is why you keep seeing conflicting answers. However there are a few that are preferred.
For screen rotation, meaning if the device is flipped horizontally or vertically you use onSaveInstanceState.
There is another method I consider cheating and many people will tell you to stay away from as it can cause many errors down the line. However it is the easiest way possible. Simply go into your manifest and place this line
android:configChanges="orientation|keyboardHidden|screenSize
If you are trying to retain information so that when you return to an Activity it is still there you should use onPause(). It appears as though you are only transferring simple data like String, int, etc. This can be done using SharedPreferences inside your onPause(). The reason is onPause() is always (99% of the time) called before the Activity is killed, meaning you will always retain your information.
For some video references to show you how to do these things go here The New Boston
If you would rather read here are some links
SharedPreferences
onPause or onPause
onSaveInstanceState
If you need anything else just ask.

When switching between the Activities you can put extras to the Intent: putExtra() like:
intent.putExtra(Intent.EXTRA_TEXT, "my saved String");
And get them in the called activity by:
String gottenString = intent.getExtras().getString(Intent.EXTRA_TEXT);
You can also save your data in a (temporary) file: Saving Files

Assigning value from Checkbox to a variable that isnt complete

sorry if this has been asked, i searched but didnt find anything. I am making a form in android and have some Checkboxes that i want to pass on if they are checked or not.
so i made the checkboxes and casted the view to checkbox so it will check any of the checkboxes i click on(Havent added the checkbox listeners yet). The problem is, when it determines a checkbox is checked i want to make the boolean that is for that box be true
EG when you tick the buy checkbox, i want the isbuyable boolean set to true. is this possible without the use of many if statements to set each one?
I made the string variable nameofboolean which is the name of the boolean to change the state but not sure how to actually change that boolean now without a multitude of IF statements checking each one.
EDIT: To clarify, all i want is to set the boolean matching each checkbox to be set to true when the checkbox is checked. I just dont want to use a lot of IFs to do it if possible.

Thanks in advance

If I understand your question, you want something like this
CheckBox buyable,rentable,hard,soft,ebook,condition,new_book,used_book;
CheckBox[] checklist={ buyable,rentable,hard,soft,ebook,condition,new_book,used_book};
int ids[]={R.id.market_buy,R.id.market_rent,R.id.market_hardcover,R.id.market_softcover,R.id.market_ebook,R.id.market_new,R.id.market_used};
in onCreate after set contentView
for(int i=0;i<checklist.length;i++)
{
checklist[i]=findViewById(ids[i]);
}
Call this method like this
String data=getAllcheckedValues();
Get all the checked values
public String getAllCheckedValues()
{
String checkItems="";
for(int i=0;i<checklist.length;i++)
{
if(checklist[i].isChecked())
{
checkItems+=checkItems+checklist[i].getText()+"is Checked"+"\n";
}
}
return checkItems;
}
Format the string according to your requirement.

Having an issue with switch statement involving Android Spinners

I'm trying to use 2 spinners on my view and at the moment implementing the "OnItemSelected" method . I have a switch statement set up to tell the spinners apart, but it doesn't seem to be working for some reason.
Here is my code:

import android.content.Intent;

Your switch is working fine. The reason it seems to be not working is because your code to display the Toast is missing the show() calls.
Instead of:
Toast.makeText(parent.getContext(), ..., Toast.LENGTH_LONG);
do this:
Toast.makeText(parent.getContext(), ..., Toast.LENGTH_LONG).show();
I make the same mistake all the time myself :)

Replace int id = parent.getId(); to int id = view.getId();

You need to switch based on the id of the view not the view adapter. Try changing int id = parent.getId(); to int id = view.getId();.

Android - how do I share a listener between a spinner and radio button?

I've tried using this link but I can't get it to work for a spinner and a radio button.
Is there a better or easier way to share a listener between various items of different varieties?
EDIT - I should have mentioned that the reason I want to share the listener is that I need to use various adapters that I'm having trouble using in other classes.

You can define a class that implement listener for both Spinner and radio button,
create one instance of the class and then assign that instance to both the radio button and the spinner.
For example:
package italialinux.example;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.TextView;
public class ButtonAction implements OnClickListener, OnItemSelectedListener {
TextView btnLocalText;
public ButtonAction(TextView tv) {
super();
btnLocalText = tv;
}
#Override
public void onClick(View arg0) {
btnLocalText.setText("Hello from a ButtonAction!!");
}
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}

If you want them to perform the same function on the click, the simply add the same listner instance in the setOnClickListener() method to each view/widget. If not then you will have to detect which view was clicked and perform the required action accordingly

i think the code example below is what you looking for
//the import for onClickListener you need is here (along with other imports --- you can get all of them by pressing ctrl+shift+o on Eclips IDE)
import android.view.View.OnClickListener;
public class MyActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Button myButton = (Button) findViewById(R.id.myButtonId);
ImageView myImageView = (ImageView) findViewById(R.id.myImageViewId);
RadioButton myRadioButton = (RadioButton) findViewById(R.id.myRadioButtonId);
CheckBox myCheckBox = (CheckBox) findViewById(R.id.myCheckBoxId);
myButton.setOnClickListener(this);
myImageView.setOnClickListener(this);
myRadioButton.setOnClickListener(this);
myCheckBox.setOnClickListener(this);
}
public void onClick(View view) {
switch (view.getId()) {
case R.id.myButtonId:
// do the work here for Button click listener
break;
case R.id.myImageViewId:
// do the work here for Image click listener
break;
case R.id.myRadioButtonId:
// do the work here for RadioButton click listener
break;
case R.id.myCheckBoxId:
// do the work here for CheckBox click listener
break;
}
}
}
