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
