EditText不可编辑

如果让EditText不可编辑在xml实现很简单android:editable 可是在代码中却没有setEditable
只能使用
editText.setFilters(new InputFilter[] { new InputFilter() {
 @Override
 public CharSequence filter(CharSequence source, int start,
  int end, Spanned dest, int dstart, int dend) {
   return source.length() < 1 ? dest.subSequence(dstart, dend) : "";
 }
} });
