如果不需要验证服务器端证书，直接照这里做。

    public class Demo extends Activity {
 
        /** Called when the activity is first created. */ 
            private TextView text;
 
        @Override
 
        public void onCreate(Bundle savedInstanceState) {
 
            super.onCreate(savedInstanceState);
 
            setContentView(R.layout.main); 
            text = (TextView)findViewById(R.id.text); 
            GetHttps();
 
        }
         
         private void GetHttps(){
 
                String https = " https://800wen.com/"; 
                try{
 
                        SSLContext sc = SSLContext.getInstance("TLS"); 
                        sc.init(null, new TrustManager[]{new MyTrustManager()}, new SecureRandom());
                         HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory()); 
                        HttpsURLConnection.setDefaultHostnameVerifier(new MyHostnameVerifier());
                        HttpsURLConnection conn = (HttpsURLConnection)new URL(https).openConnection(); 

                        conn.setDoOutput(true);
                         conn.setDoInput(true); 
                       conn.connect();                        
 
                         BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream())); 
                 StringBuffer sb = new StringBuffer(); 
                 String line; 
                 while ((line = br.readLine()) != null) 
                         sb.append(line); 
                         
                        text.setText(sb.toString());                        
 
                }catch(Exception e){ 
                        Log.e(this.getClass().getName(), e.getMessage());
 
                }                
        }
          
        private class MyHostnameVerifier implements HostnameVerifier{
 
                    @Override
 
                    public boolean verify(String hostname, SSLSession session) {
                            // TODO Auto-generated method stub
 
                            return true;
                     }
 
        }
 
            private class MyTrustManager implements X509TrustManager{
 
                    @Override
 
                    public void checkClientTrusted(X509Certificate[] chain, String authType)
 
                                    throws CertificateException {
                             // TODO Auto-generated method stub
 
                            
                    }
                    @Override
 
                    public void checkServerTrusted(X509Certificate[] chain, String authType)
 
                                    throws CertificateException {
                            // TODO Auto-generated method stub
                            
                    }
                    @Override
 
                    public X509Certificate[] getAcceptedIssuers() {
 
                            // TODO Auto-generated method stub
 
                            return null;
                    }        
        }  
 
    }
 

如果需要验证服务器端证书（这样能够防钓鱼），我是这样做的，还有些问题问大牛：
a. 导出公钥。在浏览器上用https访问tomcat，查看其证书，并另存为一个文件(存成了X.509格式：xxxx.cer)
b. 导入公钥。把xxxx.cer放在Android的assets文件夹中，以方便在运行时通过代码读取此证书，留了两个问题给大牛：

    AssetManager am = context.getAssets();
 
    InputStream ins = am.open("robusoft.cer");
 
    try {
 
            //读取证书
 
            CertificateFactory cerFactory = CertificateFactory.getInstance("X.509");  //问1
 
            Certificate cer = cerFactory.generateCertificate(ins);
 
            //创建一个证书库，并将证书导入证书库
 
            KeyStore keyStore = KeyStore.getInstance("PKCS12", "BC");   //问2
 
            keyStore.load(null, null);
 
            keyStore.setCertificateEntry("trust", cer);
 
            return keyStore;
 
    } finally {
 
            ins.close();
 
    }
 
    //把咱的证书库作为信任证书库
 
    SSLSocketFactory socketFactory = new SSLSocketFactory(keystore);
 
    Scheme sch = new Scheme("https", socketFactory, 443);
 
    //完工
 
    HttpClient mHttpClient = new DefaultHttpClient();
 
    mHttpClient.getConnectionManager().getSchemeRegistry().register(sch);
 

问1：这里用"PKCS12"不行
答1：PKCS12和JKS是keystore的type，不是Certificate的type，所以X.509不能用PKCS12代替

问2：这里用"JKS"不行。

答2：android平台上支持的keystore type好像只有PKCS12，不支持JKS，所以不能用JKS代替在PKCS12，不过在windows平台上是可以代替的
