我使用以下代码浮动编辑文本。

<android.support.design.widget.TextInputLayout
                android:id="@+id/username_text_input_layout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_centerVertical="true"
                android:layout_toLeftOf="@id/searchbtn"
                android:contentDescription="Using for Floating label">
                <EditText
                    android:id="@+id/editphone"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:hint="@string/inputNumber"
                    android:imeOptions="actionSearch"
                    android:inputType="phone"
                    android:maxLength="15" />
            </android.support.design.widget.TextInputLayout>

但它没有在预览中呈现并在android studio中获得跟随渲染问题。
