I don't think there's a good way to do it with strings like "r1c1", "r1c2" etc, but there are a couple of options: If you just need to get a valid id, you could use the static method <code>View.generateViewId()</code>. This is API level 17 though, so will only work in recent versions of Android. See here: <a href="http://developer.android.com/reference/android/view/View.html#generateViewId%28%29" rel="nofollow">http://developer.android.com/reference/android/view/View.html#generateViewId%28%29</a> An alternative would be to store references to the <code>EditText</code> objects in a two-dimensional array or list. When you need to sum up rows or columns, you'd iterate over the appropriate section of the array and go from there. A third option would be to keep a two-dimensional array of values from each <code>EditText</code> instead of the <code>EditText</code> itself. You could do this with a <code>TextWatcher</code> like this: <pre><code>// Creating EditText for (row,col) // Expand size of 2D array if necessary EditText cb = new EditText(this); cb.setLayoutParams(params); cb.setBackgroundColor(Color.parseColor("#ffffff")); cb.setInputType(InputType.TYPE_CLASS_NUMBER); // So the user can only enter numbers cb.addTextChangedListener(new TextWatcher() { public void afterTextChanged(Editable s) { mValues[row][col] = Integer.valueOf(s.toString()); } }); </code></pre> See these links for more details: <a href="https://developer.android.com/reference/android/widget/TextView.html#addTextChangedListener%28android.text.TextWatcher%29" rel="nofollow">https://developer.android.com/reference/android/widget/TextView.html#addTextChangedListener%28android.text.TextWatcher%29</a> <a href="https://developer.android.com/reference/android/text/TextWatcher.html" rel="nofollow">https://developer.android.com/reference/android/text/TextWatcher.html</a>

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.
