Answer 1

You can define your strings in an array which will help simplify this task (res/values/array.xml):

<string-array name="myArray"> 
    <item>string 1</item> 
    <item>string 2</item> 
    <item>string 3</item> 
    <item>string 4</item> 
    <item>string 5</item>
</string-array> 

You can then create an array to hold the strings and select a random string from the array to use:

private String[] myString; 

myString = res.getStringArray(R.array.myArray); 

String q = myString[rgenerator.nextInt(myString.length)];

Example code:

package com.test.test200;

import java.util.Random;

import android.app.Activity;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TextView;

public class Test extends Activity {
/** Called when the activity is first created. */

    private String[] myString;
    private static final Random rgenerator = new Random();

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    Resources res = getResources();

    myString = res.getStringArray(R.array.myArray); 

    String q = myString[rgenerator.nextInt(myString.length)];

    TextView tv = (TextView) findViewById(R.id.text1);
    tv.setText(q);
}
}

Answer 2

create string array in res/values/array.xml:

<?xml version="1.0" encoding="utf-8"?>  
    <resources>  
<string-array name="custom_array"> 
    <item>aalia</item> 
    <item>asin</item> 
    <item>sonakshi</item> 
    <item>kajol</item> 
    <item>madhuri</item>
</string-array> 
</resources>

then in your activity write the code

String[] array = context.getResources().getStringArray(R.array.custom_array);

        String randomStr = array[new Random().nextInt(array.length)];

        text_dialog.setText(""+randomStr);

Answer 3

Why do you need this?

R.string.q0

Assuming getString(RandomQ) is a valid statement, I would think

int RandomQ = rgenerator.nextInt(5) + 1;

would work just fine.

Also, as a side note: A lot of times those autofixes in your IDE are unreliable and unsafe to use. Unless you know why it's telling you to do something, don't do it.
