在其他控制器中将 webview 设置为全屏

Question

我有一个带有几个按钮和 web 视图的活动。我想在按下特定按钮时将 webview 设置为全屏，并在双击 webview 时退出全屏模式。 这是 XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

            <ImageButton
                android:id="@+id/ibNext"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/ic_action_previous_item" />
            <ImageButton
                android:id="@+id/ibPrevious"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/ic_action_next_item" />

                <LinearLayout
                    android:orientation="horizontal"
                    android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:gravity="right" >

                <ImageButton
                    android:id="@+id/ibFullScreen"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:src="@drawable/ic_action_full_screen" />

                <ImageButton
                    android:id="@+id/ibChapters"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:src="@drawable/ic_action_view_as_list" />


            </LinearLayout>


        </LinearLayout>

        <WebView
            android:id="@+id/webView1"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </LinearLayout>

</LinearLayout>

我已经有一个全屏按钮的监听器，我只需要知道如何将 webview 设置为全屏。

谢谢
