如何显示2次在1活动（机器人）？ [英] How do I display 2 views in 1 activity (android)?

问题描述

假设我有一个web视图打开：

Suppose I have a webview open:

  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    main_webv = (WebView) findViewById(R.id.mainwebview);
    main_webv.setWebViewClient(new HelloWebViewClient());
    main_webv.getSettings().setJavaScriptEnabled(true);
    main_webv.getSettings().setSupportZoom(false);
    main_webv.addJavascriptInterface(new HelloJavascriptInterface(),"hello");
    main_webv.setWebChromeClient(new HelloWebChromeClient());
    main_webv.loadUrl(SPLASH);   
    main_webv.setVisibility( 4 );

    setContentView(R.layout.main_list);         
    main_listv = (ListView) findViewById(R.id.mainlistview);    


}

我只是想创建一个的ListView 这上面的WebView（包括它......但罗纳尔多，也很想让web视图运行）。我可以打开和关闭的意见。 谢谢你。

I simply want to create a ListView above this webview (covering it up...but sitll allowing the webview to run). I could toggle the views on and off. Thanks.

推荐答案

您可以使用的FrameLayout ;这样既视图将被布置在另一个之上。然后，您可以使用 View.setVisibility（..）法切换自己的知名度。

You can use FrameLayout; that way both the Views will be arranged on top of another. You can then toggle their visibility using the View.setVisibility(..) method.

这是我的布局XML（weblister.xml）：

This is my layout XML(weblister.xml):

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <ListView
    android:id="@+id/list_view"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    />
    <WebView
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    />

</FrameLayout>

现在，我创建活动，将有两个ListView和的WebView在浏览层次结构，但其中只有一个是可见的：

Now, I create an Activity which will have both ListView and WebView in its View heirarchy but only one of them would be Visible:

public class WebAct extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.weblister);

            //setup listview
        ListView listView = (ListView) findViewById(R.id.list_view);
        listView.setAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1,
                new String[]{"One","Two"}){

        });
            // setup web view
        WebView webView = (WebView) findViewById(R.id.webview);

        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setSupportZoom(false);

        webView.loadUrl("http://www.google.com");

            // set visibility    
        listView.setVisibility(View.INVISIBLE);
        webView.setVisibility(View.VISIBLE);
    }

}

注意：的code可能是不完整的，但我希望它传达我的观点对你

Note: The code might not be complete but I hope it does convey my point to you.
