android WebView加载H5去地址栏的两种方式，先上图







四个布局文件：

activity_main.xml

android:padding="30dp">

<Button
android:id="@+id/btn_normal"
android:layout_width="match_parent"
android:layout_height="wrap_content"

4000
android:text="正常加载未处理的WebView" />

<Button
android:id="@+id/btn_noTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/btn_normal"
android:layout_marginTop="10dp"
android:text="去除标题的WebView" />

<Button

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/btn_noTitle"

</RelativeLayout>
