Question

我正面临一个非常奇怪的问题，TabHost包含2个标签，每个标签都是一个webview.Both webviews包含静态html文件。第一个Tab有一个比第二个更大的html文件。

问题是，当我单击第二个选项卡时，对话框会调整为非常小的尺寸，然后逐步调整为更大的尺寸。有没有人见过这个问题？

以下是代码：

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

    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </TabWidget>

    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:id="@+id/tab1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">


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

        <LinearLayout
            android:id="@+id/tab2"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <WebView
                android:id="@+id/whatsnew_webview"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"/>
        </LinearLayout>

    </FrameLayout>
</LinearLayout>

我已经解决了

   <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="match_parent"
        android:layout_height="match_content">
    </TabWidget>

并设置TabHost minwith和minheight

TabHost中的WebView - 慢慢调整大小
