Android - Limit only one decimal point enter into a EditText

I need help to only allow one decimal point to be entered into a EditText view. An example: I don't want 123.45.2 or 123..452 to be allowed. Once one decimal point is entered, no more are allowed.

You can set it up in the xml layout:

<EditText
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:inputType="numberDecimal"    
/>

There's flags you can set so you don't have to do what rochdev (no offense of course) posted.

mEditText.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

This will only allow numbers to be entered and only one decimal point.

Play around with this however you like it.

myEditText.setKeyListener(DigitsKeyListener.getInstance(true,true));

Returns a DigitsKeyListener that accepts the digits 0 through 9, plus the minus sign (only at the beginning) and/or decimal point (only one per field) if specified.
