我正在尝试使用基于Worklight表单的身份验证的本机android项目。我已经能够通过本机API对用户进行身份验证。当我在活动（意图）之间切换时会出现问题。用户输入其信息并提交表单后，将对其进行身份验证，但工作灯服务器连接将丢失。 这是代码：
MainActivity.java
public class MainActivity extends Activity {
private Button buttonConnect = null;
private Button buttonInvoke = null;
private static TextView textView = null;
private static MainActivity _this;
private MyChallengeHadler challengeHandler;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
_this = this;
buttonConnect = (Button)findViewById(R.id.buttonConnect);
buttonInvoke = (Button)findViewById(R.id.buttonInvoke);
textView = (TextView)findViewById(R.id.textView);
final WLClient client = WLClient.createInstance(this);
buttonConnect.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
updateTextView("Connecting...");
client.connect(new MyConnectListener());
challengeHandler = new MyChallengeHadler(MainActivity.this, "BasicAuth");
client.registerChallengeHandler(challengeHandler);
}
});
buttonInvoke.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
updateTextView("Invoking procedure...");
String adapterName = "RSSReader";
String procedureName = "getStoriesFiltered";
WLProcedureInvocationData invocationData =
new WLProcedureInvocationData(adapterName, procedureName);
Object[] parameters = new Object[] {"world"};
invocationData.setParameters(parameters);
WLRequestOptions options = new WLRequestOptions();
options.setTimeout(30000);
WLClient client = WLClient.getInstance();
client.invokeProcedure(invocationData, new MyInvokeListener(), options);
}
});
}
public static void updateTextView(final String str){
Runnable run = new Runnable() {
public void run() {
textView.setText(str);
}
};
_this.runOnUiThread(run);
}
}
LoginActivity.java
public class LoginActivity extends Activity {
private Button Submit = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Submit = (Button)findViewById(R.id.button1);
Submit.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
MyChallengeHadler challengeHandler = new MyChallengeHadler(LoginActivity.this, "BasicAuth");
challengeHandler.submitLogin(0, "maria", "maria", false);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.login, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
MyChallengeHadler.java
public class MyChallengeHadler extends ChallengeHandler {
private WLResponse cachedResponse;
private final Activity parentActivity;
public MyChallengeHadler(final Activity a, String realm) {
super(realm);
this.parentActivity =a;
// TODO Auto-generated constructor stub
}
@Override
public void onFailure(WLFailResponse arg0) {
// TODO Auto-generated method stub
}
@Override
public void onSuccess(WLResponse arg0) {
// TODO Auto-generated method stub
}
@Override
public boolean isCustomResponse(WLResponse response) {
if (response == null || response.getResponseText() == null
|| response.getResponseText().indexOf("j_security_check") == -1) {
return false;
}
return true;
}
@Override
public void handleChallenge(WLResponse response){
if (!isCustomResponse(response)) {
submitSuccess(response);
} else {
cachedResponse = response;
Intent login = new Intent(parentActivity, LoginActivity.class);
parentActivity.startActivityForResult(login, 1);
}
}
public void submitLogin(int resultCode, String userName, String password, boolean back){
HashMap<String, String> params = new HashMap<String, String>();
params.put("j_username", userName);
params.put("j_password", password);
submitLoginForm("/j_security_check", params, null, 0, "post");
Intent login = new Intent(parentActivity, MainActivity.class);
parentActivity.startActivityForResult(login, 1);
}
}
答案 0 :(得分：0)
我已经解决了我的代码问题。我错误地使用了android的意图。这是代码的新版本：
<强> LoginActivity.java
public class LoginActivity extends Activity {
private Button Submit;
private Intent result;
public static final String Back = "back";
public static final String UserNameExtra = "username";
public static final String PasswordExtra = "password";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Submit = (Button)findViewById(R.id.button1);
result = new Intent();
Submit.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
result.putExtra(UserNameExtra, "maria");
result.putExtra(PasswordExtra, "maria");
result.putExtra(Back, false);
setResult(RESULT_OK, result);
finish();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.login, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
