    <p>I am trying to do something extremely basic! And it wont work :(. I feel like I'm going in circles.</p> <p>Here's the rundown: I would like the user to input a series of numbers into an EditText box (separated by comma's). After the add button is selected a split method will separate each number into its own slot in a String[]. EVENTUALLY, if I can get this part to work, the numbers will be pulled out of the array and converted to doubles.Then they will be used in a calculation or two. I have tried several different ways of getting this done and it seems like the problem is coming from the split method or for-loop. The code listed below returns an empty string.</p> <p>Also, through my trial and error I ended up with a return method calculate(). How much stuff can a cram in an onClick method? Was this a bad idea? Please be as a brutal as needed!!! I'm new to android. Thanks in advance.</p> <hr> <pre><code>package com.simplydesign.android.standarddev; import android.app.Activity; import android.os.Bundle; import android.widget.*; import android.view.*; public class Main extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Button addBtn = (Button) findViewById(R.id.addBtn); final EditText userData = (EditText) findViewById(R.id.editText1); final TextView dataCollection = (TextView) findViewById(R.id.textView1); addBtn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String[] rawData; rawData = userData.getText().toString().split(","); dataCollection.setText(calculate(rawData)); } }); } public String calculate(String[] a) { String output = ""; for (int i = 0; i &lt; a.length - 1; i++) { output += " " + a[i]; } return output; } } </code></pre>

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.
