how to make edittext field for decimals

Question

how to make dynamically edittext field for accepting only double and float values?

Answer 1

Use this method in your Activity:

EditText et = (EditText) findViewById(R.id.text01);
et.setInputType(0x00002002);

or

EditText et = (EditText) findViewById(R.id.text01) ;
et.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

here text01 is id of EditText field in your R.java file;

Answer 2

Maybe a nicer solution would be using

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

Edit: I have also added the flag InputType.TYPE_NUMBER_FLAG_DECIMAL to accept dobules too.
