android: the first digit in the edit text can not be zero
android, android-edittext, input-mask
Solution
There is an alternative way in which you can use `textWatcher`. Check the length of editable text inside `afterTextChange` method. If the length is 1 and the string is 0 then remove 0.
Problem
I have an EditText element with a number input type. I don't want users to be able to enter 0 as the first digit. Can I enforce this using XML? Here is what I have currently: ``` <EditText android:id="@+id/main_edt_loan" android:layout_width="fill_parent" android:layout_height="40dip" android:background="@drawable/sample_editbox" android:ems="10" android:layout_margin="10dip" android:inputType="number" android:hint="" android:ellipsize="start" android:maxLines="1" android:imeOptions="actionNext" android:textSize="18dip" android:gravity="center" android:digits="0123456789" android:maxLength="10" android:textColor="#000000"/> ```
