POAndroid 4.+ NumberPicker - Forcing Number Keyboard Layout
text
Body
copied!<p>Am posting this in hopes to help someone else; but, if there is an easier way to do the same, I hope someone can share their steps. If I use the method 'setDisplayedValues' to pass an array of values to display in the NumberPicker, the underlying method forces the use of a Text Keyboard Layout, instead of the Number Layout, which isn't what I want. I found a way to set the InputType for my NumberPicker. This is done in my extended class:</p> <p><strong>class public class NumberPickerDialogFragment extends DialogFragment</strong>:</p> <pre><code>@Override public Dialog onCreateDialog(Bundle savedInstanceState) { // We are getting the parameters passed in to figure out the range of the Number Picker NumPickerValues = getArguments().getStringArray("NumPickerRange"); AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); // Get the layout inflater LayoutInflater inflater = getActivity().getLayoutInflater(); View dlgNumPicker = inflater.inflate(R.layout.dialog_num_picker, null); NumberPicker np = (NumberPicker) dlgNumPicker.findViewById(R.id.npNumberPicker); // Always remember that NumberPicker methods need an index position, rather than the value in that array position np.setMinValue(0); np.setMaxValue(NumPickerValues.length-1); np.setDisplayedValues(NumPickerValues); np.setValue(getArguments().getInt("InitialValue")); np.setWrapSelectorWheel(false); np.setOnValueChangedListener(this); // Since the underlying code for the NumberPicker sets the keyboard layout for text, due to the use of 'setDisplayedValues', // we need to set it back to a number keyboard layout ((EditText)np.getChildAt(0)).setRawInputType(InputType.TYPE_CLASS_NUMBER); // Inflate and set the layout for the dialog // Pass null as the parent view because its going in the dialog layout return builder.setView(dlgNumPicker) .setTitle(getArguments().getInt("NumPickerTitle")) .setPositiveButton(getArguments().getInt("SaveButtonTitle"), new ButtonCLickListener()) .setNegativeButton(R.string.cancel, new ButtonCLickListener()) .create(); } </code></pre> <p>On the section of code above, the line that sets the InputType is <strong>((EditText)np.getChildAt(0)).setRawInputType(InputType.TYPE_CLASS_NUMBER);</strong></p> <p>I didn't find anything on the web that does this. It seems like a clean way of doing it; but, am not sure if there is any performance issues by doing it this way. If there is, let us know.</p>
