+An input dialog is pretty self explanatory, it retrieves input from the user of your application with
+an input field (EditText). You can also display content above the EditText if you desire.

+new MaterialDialog.Builder(this)

+        .content(R.string.input_content)
+        .input(R.string.input_hint, R.string.input_prefill, new MaterialDialog.InputCallback() {
