I hope you will help me to fix this problem . Thank you.

Here is your solution.
First replace your main activity listView.setOnItemClickListener=> onItemClick method with below code
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String stateName = listView.getAdapter().getItem(position).toString();
int pos=0;
for(int i=0;i<stateList.length;i++)
{
if(stateList[i].equals(stateName))
{
pos=i;
break;
}
}
// Put selected state to intent.
Intent intent = new Intent(MainActivity.this, NextActivity.class);
intent.putExtra("selectedState", stateName);
intent.putExtra("anotherStringArray", anotherStringArray[pos]);
startActivity(intent);
}
});
And also make your stateList array and and anotherStringArray as same size in string.xml file.
<string-array name="stateList">
<item>Abstract Window Toolkit (AWT)</item>
<item>abstract</item>
<item>abstract class</item>
<item>abstract method</item>
<item>access control</item>
<item>ACID</item>
<item>activation</item>
<item>actual parameter list</item>
<item>alpha value</item>
</string-array>
<string-array name="anotherStringArray">

How to enable disabled submit button after any one of the radioButton of RadioGroup?

Here I am trying to make an app where I have 4 options on my MainActivity Screen, User should able to Click on submit only when one of the radio button is selected.(OTHERWISE NOT), which help me to avoid null pointer Exception while submitting the option.

radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener()

public void onCheckedChanged(RadioGroup group, int checkedId) {
boolean is=group.isActivated(); //This must be something else,Please suggest
if(is==true)
{
submit.setEnabled(true);
}
else
{

}
}
});

<string name="option4">Pink</string>

try this
if (checkedId == R.id.radioButton1) {
//do something
} else if (checkedId == R.id.radioButton2) {
//do something

Actually I think, that if you receive a OnCheckChanged event, is because one of the radiobutton was selected.
OnCheckChanged -> "Called when the checked radio button has changed."
So there is no need to check, because one of then was already selected.
You don't need to do this:
if(is==true)
{
submit.setEnabled(true);
}
else
{
submit.setEnabled(false);
}
Because on a radiogroup once you select one of then, then always there will be one selected.

First of all you are writing Button ENABLE OR DISABLE code inside CheckChanged Event of Radiogroup which will never call if any radio button is not selected.
Updated code:::::
try the below code for what you want.
// get selected radio button from radioGroup
int selectedId = radioOptions.getCheckedRadioButtonId();
if(selectedId == null || selectedId < 1)
{
submit.setEnabled(false);
}
else
{
submit.setEnabled(true);
}
Hope this helps you.

write multiple strings to a file and add a new line

I'm building a basic app that you choose from a spinner, select a color and click save. If the color you're looking for isn't in the spinner, you press a button and you can type it in to the EditText.
I'm trying to make it so I can write both the chosen spinner/edittext color and the date inside of the "colors.txt" file. at the moment, there are no errors but when i launch the app on my android it instantly crashes.
Colorchooser.java
package com.example.scalendar;
import java.io.IOException;
import java.io.OutputStreamWriter;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.util.Log;
import android.view.Menu;
public class Colorchooser extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_colorchooser);
}
public void writetoFile(String str) {
try {
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(openFileOutput("colors.txt", Context.MODE_PRIVATE));
outputStreamWriter.write("colorstring , datestring");
outputStreamWriter.close();
}
catch (IOException e) {
Log.e("Exception", "File write failed: " + e.toString());
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.colorchooser, menu);
return true;
}
}`
And here is my Strings.XML file
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">SCalendar</string>
<string name="action_settings">Settings</string>
<string name="color_prompt">What was todays color?</string>

<string name="textfieldhint">Enter color</string>

It seems you have some major misunderstandings on the relation between Java strings vs string variables, and string variables vs string resources:
This:
outputStreamWriter.write("colorstring , datestring");
Will always write "colorstring, datestring" to your file, so the file will look like:
colorstring, datestring
colorstring, datestring
colorstring, datestring
You cannot expect Java code in your string resources to be executed:
<string name="colorstring">
colorSpinner = findViewById(R.id.colorSpinner)
colorSpinner.getSelectedItem().toString()
</string>
Strings in your resources are Constants. There is no way to change them at run time.

so what i am tring to do is, i am having a book like-app, and want to setup a button when click it change the textview to a string in the #string rec. but in a different way
i will put the code just a moment, lets say i have a string in #string that is NH1,NH2,NH3
i can do for button View.setText(R.string.NH1); that will work but i want to create a counter and make it so every time clicked counter++ and want it to be like this View.setText(R.string.NH+counter); if you know what i mean so each time it clicked to goes to next #string without changing layout every time and without an array because the paragraph are very long
also if i have NH1-10 and the counter did not stop and still goes on what will i do.
if you are sill here thank you for reading.

You could do this by creating an XML string array, so your strings will still be referenced in resources, but you'll be able to loop through them.
Something like this, in values/strings.xml:
<string-array name="planets_array">
<item>Mercury</item>
<item>Venus</item>
<item>Earth</item>
<item>Mars</item>
</string-array>
And then in Activity:
Resources res = getResources();
final String[] planets = res.getStringArray(R.array.planets_array);
findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter < planets.length) {
textView.setText(planets[counter]);
counter++;
}
}
});
Be sure to check the counter against arrays length, otherwise you will get an IndexOutOfBoundsException.
