    <p>I'm trying to produce a simple oracle app where when you ask the app a question it spits out an answer based on a random number.</p> <p>I've done some research and it seems to me the best practice way of doing things is to create a resource for my answers containing a string array, i can then type my various answers in to the array.</p> <p>In my Java code in my main activity i can then generate a random number upon the click of a button. This random number can then correspond to the number of the index.</p> <p>My problem comes when i try to piece the random number and the facility to access the string array together in code.</p> <p>Here is a copy of my answerStrings.xml file</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;resources&gt; &lt;string-array name="answers"&gt; &lt;item&gt;Yes&lt;/item&gt; &lt;item&gt;No&lt;/item&gt; &lt;item&gt;Maybe&lt;/item&gt; &lt;item&gt;Quite possibly&lt;/item&gt; &lt;/string-array&gt; &lt;/resources&gt; </code></pre> <p>Here is my java code:</p> <pre><code>import java.util.Random; import android.app.Activity; import android.content.res.Resources; import android.media.MediaPlayer; import android.os.Bundle; import android.os.Vibrator; import android.view.View; import android.view.View.OnClickListener; import android.widget.TextView; public class MainActivity extends Activity implements OnClickListener { TextView outputText; MediaPlayer mpGobble; Vibrator vibr; String[] answers; private Random myRandom = new Random(); int randomNumber; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //find the output text view for use within the activity outputText = (TextView)findViewById(R.id.textView01); outputText.setOnClickListener(this); //Declare an array of outputs Resources res = getResources(); String[] answers = res.getStringArray(R.array.answers); //--------^ Problem outputText.setText("Ask your question then click me"); } @Override public void onClick(View src) { switch(src.getId()){ case R.id.textView01: //creates a random number int randomNumber = myRandom.nextInt(3); String answer = answers[randomNumber]; outputText.setText(answer); break; } } } </code></pre> <p>I'm programming in Java with the eclipse IDE and as you have probably guessed i'm new to the game!</p> <p>All help is much appreciated!!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
