The aim is that store the string in the normal listview and then user touch(click) it move to next page along with user selected item. Once user click "Reject button" in the Operation.java, the should go-off from the List.java activity. It is not happening. It shows "Unfortunately, System has stopped".

In the setOnClickListener under Operation.java, you are trying to start another activity. Instead, insert code to manually destroy the activity. You can also use the finish() method. Here's a link to know more about it:

I have an application that populates a ListView with user input data from another Activity ; however, whenever I enter that data into the second Activity then return to the ListView activity I see it populated with the values I entered. But, if I return to the second activity again, enter the values, and go back to the ListView activity, I see the new values updated but the old ones have disappeared.
Now, I don't know if I'm not updating the listview correctly or if I need to use sqlite databases to store this data or shared preferences in order to update the listview to new data while containing the previous information.
Thanks for any help.

It seems like you are replacing new list in listview rather to updating old list of listview.
When you come first time on activity A, you should create one global array list where you add all items which are added by user.
Now, when user go on Activity B and add any item, you should carry out value back to Activity A and add that item in list.
After adding that in list, you should notify data to Adapter. So, here your list will have 2 items and it will show on Activity A 2 items.
Unfortunately I have been banging my head against the wall for quite some time trying to figure out why the app crashes every time I press the "Display" button. As you can see an intent is called when the button is pressed, which should subsequently "change" to the GraphicDisplay Activity. Any help is appreciated.

I think I see your problem. You call inside display ClickListener:
String colorSchemeVal = popupMenu.toString();
but you never initialize "popupMenu", unless you hit "colorScheme".

String Subject_number;
//initialize your arraylist inside the loop for each row

ArraySubject_number.add(Subject_number);
//outside for loop

intent.putExtras("subject_number", ArraySubject_number);
then in your other activity use this code to access them
ArrayList<String> ArraySubject_number = (ArrayList<String>) getIntent().getSerializableExtra("subject_number");

Just glancing over your code, a possible solution (and perhaps not the best) would be to make the ID Button variable global. You would then instantiate it in the onCreate whilst still allowing it to be manipulated in other classes in this MenuActivity.
I hope this helps.
I am new to android. I am stuck with the spinner. There are two spinner item "FROM" and "TO".
I want to code as..if I want to search FROM Place1, To Place2. Then after clicking button, if condition matches, it should redirect to another page.
While running app, I am not getting any error, and no response comes out of clicking button.
Please see the below code. I have tried this thing by 3 way (*in comments), none of them gives desired output.

use this one
spinner.setOnItemSelectedListener(new Spinner.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> main, View view, int position,
long Id) {
if(position==0){
//your code
}
if(position==1){
//your code
}
}
}
use this-
if(str1.equals("plot16")&&str2.equals("plot17")){
//do functionality
}
if (str1.equals( plot31) && str2.equals(plot314))
{
Intent i = new Intent(SelectLocation.this, Route1.class);
startActivity(i);

try this. == is used to compare the references whereas equals() method is used to compare values.
