如何显示活动内的网页视图在屏幕的中间

问题描述

结果我遇到的问题，同时显示在屏幕的中间在活动的WebView。
我有一个活动，我想在显示屏幕中心网页视图。我的活动是透明的，所以后台活动将是可见的。每当我尝试创建一个web视图并使用的setContentView（web视图），将其添加到活动它总是显示在屏幕的左上角的视图。是他们的方式来解决这个？我试图通过纯$ C $这样做仅C。这里是我的code

I am having issue while showing a WebView in an activity in the middle of the screen.I have an activity and I want to show a webview in the center of screen. My activity is transparent so background activity will be visible. Whenever I try to create a webview and add it to activity using setContentView(webview) it always shows the view on the top left corner of the screen. Is their a way to workaround this?I am trying to do this via pure code only. Here is my code.

protected void onCreate(Bundle savedInstance) {
    //some initialization stuff
    LinearLayout ll = new LinearLayout(activity);
    ll.setOrientation(LinearLayout.VERTICAL);
    ll.setGravity(Gravity.CENTER_HORIZONTAL);
    ll.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,
                        ViewGroup.LayoutParams.FILL_PARENT));
    ll.setBackgroundColor(android.R.color.transparent);
    ll.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL); //added after suggestion
    webView = new WebView(this);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setBuiltInZoomControls(true);
    webView.loadUrl("http://www.google.com");
    ll.addView(webView);
    webView.setBackgroundColor(android.R.color.transparent);
    setContentView(ll);
}

推荐答案

的setContentView（的WebView）是不可能的，你确定你在这里传递web视图作为参数？它应该是一个id到布局资源。还是你的意思 addView ？

setContentView(webview) is not possible, are you sure you're passing the webView here as param? It should be an id to a layout resource. Or do you mean addView?

您应该放置在布局资源的WebView并添加layout_gravity属性，以

You should place the WebView in a layout resource and add the layout_gravity attributes, to

layout_gravity="center_horizontal|center_vertical"

和/或周围的LinearLayout或任何你使用：

and/or the surrounding linearLayout or whatever you use to:

gravity="center_horizontal|center_vertical"

请更多的澄清提供您code。

Please provide your code for more clarification.
