This is my xml

    &lt;android.support.design.widget.TextInputLayout
                    style=&quot;@style/main_input_text&quot;
                    android:layout_marginTop=&quot;@dimen/activity_medium_margin&quot;
                    app:hintTextAppearance=&quot;@style/TextAppearence.App.TextInputLayout&quot;&gt;
    
                    &lt;android.support.v7.widget.AppCompatEditText
                        style=&quot;@style/main_edit_text&quot;
                        android:inputType=&quot;text&quot; /&gt;
    
    &lt;/android.support.design.widget.TextInputLayout&gt;


And this is style

 

    &lt;style name=&quot;main_input_text&quot;&gt;
            &lt;item name=&quot;android:layout_width&quot;&gt;match_parent&lt;/item&gt;
            &lt;item name=&quot;android:layout_height&quot;&gt;@dimen/activity_edittext_height&lt;/item&gt;
            &lt;item name=&quot;android:background&quot;&gt;@drawable/mc_shape_border_button_transparent&lt;/item&gt;
            &lt;item name=&quot;android:gravity&quot;&gt;center_vertical&lt;/item&gt;
            &lt;item name=&quot;android:paddingTop&quot;&gt;@dimen/activity_extra_small_margin&lt;/item&gt;
            &lt;item name=&quot;android:paddingBottom&quot;&gt;@dimen/activity_extra_small_margin&lt;/item&gt;
            &lt;item name=&quot;android:keyTextSize&quot;&gt;8sp&lt;/item&gt;
            &lt;item name=&quot;android:textSize&quot;&gt;8sp&lt;/item&gt;
    &lt;/style&gt;
