    <p>For anyone else wondering how to achieve this, here is my extended <code>EditText</code> class <code>EditTextNumeric</code>.</p> <p><code>.setMaxLength(int)</code> - sets maximum number of digits</p> <p><code>.setMaxValue(int)</code> - limit maximum integer value</p> <p><code>.setMin(int)</code> - limit minimum integer value</p> <p><code>.getValue()</code> - get integer value</p> <pre><code>import android.content.Context; import android.text.InputFilter; import android.text.InputType; import android.widget.EditText; public class EditTextNumeric extends EditText { protected int max_value = Integer.MAX_VALUE; protected int min_value = Integer.MIN_VALUE; // constructor public EditTextNumeric(Context context) { super(context); this.setInputType(InputType.TYPE_CLASS_NUMBER); } // checks whether the limits are set and corrects them if not within limits @Override protected void onTextChanged(CharSequence text, int start, int before, int after) { if (max_value != Integer.MAX_VALUE) { try { if (Integer.parseInt(this.getText().toString()) &gt; max_value) { // change value and keep cursor position int selection = this.getSelectionStart(); this.setText(String.valueOf(max_value)); if (selection &gt;= this.getText().toString().length()) { selection = this.getText().toString().length(); } this.setSelection(selection); } } catch (NumberFormatException exception) { super.onTextChanged(text, start, before, after); } } if (min_value != Integer.MIN_VALUE) { try { if (Integer.parseInt(this.getText().toString()) &lt; min_value) { // change value and keep cursor position int selection = this.getSelectionStart(); this.setText(String.valueOf(min_value)); if (selection &gt;= this.getText().toString().length()) { selection = this.getText().toString().length(); } this.setSelection(selection); } } catch (NumberFormatException exception) { super.onTextChanged(text, start, before, after); } } super.onTextChanged(text, start, before, after); } // set the max number of digits the user can enter public void setMaxLength(int length) { InputFilter[] FilterArray = new InputFilter[1]; FilterArray[0] = new InputFilter.LengthFilter(length); this.setFilters(FilterArray); } // set the maximum integer value the user can enter. // if exeeded, input value will become equal to the set limit public void setMaxValue(int value) { max_value = value; } // set the minimum integer value the user can enter. // if entered value is inferior, input value will become equal to the set limit public void setMinValue(int value) { min_value = value; } // returns integer value or 0 if errorous value public int getValue() { try { return Integer.parseInt(this.getText().toString()); } catch (NumberFormatException exception) { return 0; } } } </code></pre> <p>Example usage:</p> <pre><code>final EditTextNumeric input = new EditTextNumeric(this); input.setMaxLength(5); input.setMaxValue(total_pages); input.setMinValue(1); </code></pre> <p>All other methods and attributes that apply to <code>EditText</code>, of course work too.</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.
