How to disable Android Soft Keyboard for a particular activity?

Question

I have an activity with one EditText where I need to input numbers only.

Now, I have defined the Input Type for my EditText to be number only and have drawn up a pretty keypad for my user to use, however I also need to make sure the soft keyboard doesn't pop up for my user when they click on the EditText.

I have tried hiding the keyboard through the manifest by adding

android:windowSoftInputMode="stateAlwaysHidden"

in my Manifest for the particular activity, but this doesn't work for me because as soon as the user clicks on the EditText the keyboard appears again.

I've tried doing the same programmatically like so

activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

but that doesn't work either. Keyboard appears when the user clicks on the EditText.

The only thing that worked was setting InputType to null for the EditText like so:

EditText.setInputType(InputType.TYPE_NULL);

but I cannot use this because it will allow users who have a keyboard attached to their device to input letters and other symbols in the EditText field, while I want everyone to specifically use only the keypad to enter data in the field.

I should also mention that I am currently testing my app under android 2.1, but I would like my solution to work across all versions. Any help would be appreciated. Thanks in advance.

You can try this. It is working for me:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
                     WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
