controlling text input in edittext

Question

I have an EditText where the user can enter three words. How do I prevent the user from entering more words? The user also has to be able to erase what they've entered and enter three new words.

Answer 1

try using this in your xml :

<EditText 
...
android:maxLength="3" />

or this in your java code :

EditText input = (EditText) findViewById(R.id.your_editTextId);
InputFilter[] FilterArray = new InputFilter[1];
FilterArray[0] = new InputFilter.LengthFilter(3);
input.setFilters(FilterArray);
