I am trying to ignore the enter key, but i do not want to use onKeyDown() function.

There is a way to do this in xml: 1. android:maxLines = "1" 2. android:lines = "1" 3. android:singleLine = "true"

I actually want to do the last one by coding. Does anyone know how to do that?

for (int i=0; i<numClass; i++) {

        temp_ll = new LinearLayout(this);
        temp_ll.setOrientation(LinearLayout.HORIZONTAL);
        temp1 = new EditText(this);
        InputFilter[] FilterArray = new InputFilter[1];
        FilterArray[0] = new InputFilter.LengthFilter(12);
        temp1.setFilters(FilterArray);  // set edit text length to max 12
        temp1.setHint("  class name  ");
        temp1.setSingleLine(true);

        temp_ll.addView(temp1);
        frame.addView(temp_ll);
    }

    ll.addView(frame);
