XML的程式碼：

<EditText
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/text"
        android:layout_alignParentEnd="true"
        android:text="獲取" />

    <TextView
        android:id="@+id/textview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/text"
        android:layout_margin="5dp"
        />
