首先是布局文件

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/activity_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        tools:context="com.bwie.test.xuejian1508a20170927.MainActivity">
    
        <TextView
            android:id="@+id/WebUrl"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Hello World!" />
        <WebView
            android:layout_below="@+id/WebUrl"
            android:id="@+id/WebView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"></WebView>
    </RelativeLayout>

以下是具体的代码

String WebUrl="http://www.baidu6666.com";
        private String initUrl;
        private TextView webtext;
        private WebView webView;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            initView();
    
            initUrl =  initUrl();
            webtext.setText(initUrl);
            /*webView*/
            initWebView();
        }
        /*加载页面*/
        private void initWebView() {
            webView = (WebView) findViewById(R.id.WebView);
    
            webtext.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    /*加载网页*/
                    webView.setWebViewClient(new WebViewClient(){
                        /*加载网页*/
                        @Override
                        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                            return false;
                        }
                    });
                    webView.loadUrl(initUrl);
                }
            });
        }
    
        private void initView() {
            webtext =  (TextView) findViewById(R.id.WebUrl);
            webtext.getPaint().setFlags(Paint.UNDERLINE_TEXT_FLAG);
        }
    
        /*截取链接*/
        private String initUrl() {
            StringBuffer stringBuffer = new StringBuffer(WebUrl);
            StringBuffer strUrl = stringBuffer.delete(16, 20);
            return  strUrl.toString();
        }

不要忘了权限：

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
