Disable soft keyboard on NumberPicker

Question

I\'m trying to deactivate the soft keyboard when using a NumberPicker to enter numerical values (for aesthetic reasons). This is my layout-xml-code:

Answer 1

Just found this and it works like a charm:

myNumberPicker.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);

You can also set this in XML:

android:descendantFocusability="blocksDescendants" 

Answer 2

Working code Programatically :

mp.setDescendantFocusability(NumberPicker.FOCUS_BLOCK_DESCENDANTS);

XML:

android:descendantFocusability="blocksDescendants" 

Answer 3

After reading through the com/android/internal/widget/NumberPicker.java source code i got to the following solution:

// Hide soft keyboard on NumberPickers by overwriting the OnFocusChangeListener
OnFocusChangeListener fcl = new OnFocusChangeListener() {
    public void onFocusChange(View v, boolean hasFocus) {
        // Do nothing to suppress keyboard
    }
};

((EditText) numberPicker.getChildAt(1)).setOnFocusChangeListener(fcl);

// Suppress soft keyboard from the beginning
((EditText) numberPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);

Answer 4

The simplest I found to work was :

numberPicker               = (NumberPicker) myDialogView.findViewById(R.id.myViewId);
EditText numberPickerChild = (EditText) numberPicker.getChildAt(0);
numberPickerChild.setFocusable(false);
numberPickerChild.setInputType(InputType.TYPE_NULL);

Answer 5

I don't know why it works, but setting OnClickListener which does nothing prevented keyboard from showing (Lollipop)

numberPicker.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View view) {
  }
});
