How to programmatically set maxLength in Android TextView?

Question

I would like to programmatically set maxLength property of TextView as I don\'t want to hard code it in the layout. I can\'t see any set

Answer 1

My solution for SWIFT 5

editText.filters = arrayOf<InputFilter>(InputFilter.LengthFilter(123))

Answer 2

As João Carlos said, in Kotlin use:

editText.filters += InputFilter.LengthFilter(10)

(Add android:inputType="textNoSuggestions" to your EditText.)

Answer 3

     AlertDialog.Builder builder = new AlertDialog.Builder(this);
                    builder.setTitle("Title");


                    final EditText input = new EditText(this);
                    input.setInputType(InputType.TYPE_CLASS_NUMBER);
//for Limit...                    
input.setFilters(new InputFilter[] {new InputFilter.LengthFilter(3)});
                    builder.setView(input);

Answer 4

To keep the original input filter, you can do it this way:

InputFilter.LengthFilter maxLengthFilter = new InputFilter.LengthFilter(100);
        InputFilter[] origin = contentEt.getFilters();
        InputFilter[] newFilters;
        if (origin != null && origin.length > 0) {
            newFilters = new InputFilter[origin.length + 1];
            System.arraycopy(origin, 0, newFilters, 0, origin.length);
            newFilters[origin.length] = maxLengthFilter;
        } else {
            newFilters = new InputFilter[]{maxLengthFilter};
        }
        contentEt.setFilters(newFilters);

Answer 5

Try this

int maxLengthofEditText = 4;    
editText.setFilters(new InputFilter[] {new InputFilter.LengthFilter(maxLengthofEditText)});

Answer 6

For those of you using Kotlin

fun EditText.limitLength(maxLength: Int) {
    filters = arrayOf(InputFilter.LengthFilter(maxLength))
}

Then you can just use a simple editText.limitLength(10)
