Answer 1

Use numberSigned along with numberDecimal (assuming you are interested in positive integers only otherwise numberDecimal is fine):-

android:inputType="numberDecimal|numberSigned"

You can also set it up from Java src:-

edit_text.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_SIGNED);

Now to read the value entered do this:-

EditText mEdit   = (EditText)findViewById(R.id.editText1);
String value = mEdit.getText().toString();

Checked and tested this code, it works fine.

    String str = editText.getText().toString();

    float f = Float.parseFloat(str);

    double d = Double.parseDouble(str);

    System.out.println("str :" + str + "\nfloat :" + f+ "\ndouble :" + d);
