我使用我编码的应用程序登录公司网页时遇到问题。当我使用toast消息时，它可以判断登录是否成功。但是当我插入INTENT并转移到下一个将查看网页内容的活动时（成功登录后）我只能查看公司的“LOGIN WEBPAGE”，而不是内容。我非常感谢您提供正确的代码或添加到我的代码中。提前谢谢。
以下是我的代码：
这是我们公司的网页：http://www.allianceinmotion.com/members.asp
登录活动：
package com.example.packagename;
imports ..... ;
public class LoginActivity extends Activity implements OnClickListener {
private ProgressDialog pDialog;
private static final String LOGIN_URL = "http://vo.aimglobalinc.com/control/con_login.asp";
JSONParser jsonParser = new JSONParser();
Boolean isInternetPresent = false;
private EditText user, pass;
private Button mSubmit, mRegister;
ConnectionDetector cd;
@Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
Intent i1 = getIntent();
i1.getExtras().getInt("login");
setResult(RESULT_OK, i1);
cd = new ConnectionDetector(getApplicationContext());
user = (EditText)findViewById(R.id.txt_username);
pass = (EditText)findViewById(R.id.txt_password);
mSubmit = (Button)findViewById(R.id.btn_login);
mRegister = (Button)findViewById(R.id.btn_register);
mSubmit.setOnClickListener(this);
mRegister.setOnClickListener(this);
}
@Override
public void onClick(View v) {
isInternetPresent = cd.isConnectingToInternet();
switch (v.getId()) {
case R.id.btn_login:
if (isInternetPresent) {
new AttemptLogin().execute();
}else {
Toast.makeText(LoginActivity.this, "This requires an internet connection.", Toast.LENGTH_LONG).show();
}
break;
case R.id.btn_register:
//Intent i = new Intent(this, RegisterActivity.class);
//startActivity(i);
break;
default:
break;
}
}
class AttemptLogin extends AsyncTask<String, String, String> {
boolean failure = false;
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(LoginActivity.this);
pDialog.setMessage("Attempting to login...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected String doInBackground(String... args) {
String username = user.getText().toString();
String password = pass.getText().toString();
try {
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("uname", username));
params.add(new BasicNameValuePair("pword", password));
Log.d("request!", "starting");
JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "POST", params);
Log.d("Login attempt", json.toString());
return json.getString("success");
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String result) {
super.onPostExecute(result);
pDialog.dismiss();
if (result.equals("true")) {
Toast.makeText(LoginActivity.this, "Login Successful!", Toast.LENGTH_LONG).show();
Intent i = new Intent(LoginActivity.this, MyAccounts.class);
finish();
startActivity(i);
} else {
Toast.makeText(LoginActivity.this, "Please enter the correct username and password.", Toast.LENGTH_LONG).show();
}
}
}
}
MYACCOUNTS ACTIVITY（我想在成功登录后访问页面内容）
package com.example.packagename;
imports ..... ;
public class MyAccounts extends Activity {
private WebView mWebView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
mWebView = new WebView(this);
mWebView.loadUrl("http://www.allianceinmotion.com/members.asp");
//mWebView.loadUrl("http://vo.aimglobalinc.com/r2bs.asp");
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
this.setContentView(mWebView);
}
@Override
public boolean onKeyDown(final int keyCode, final KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
使用jsonlint.org，当我从LOGIN活动验证URL时，输出如下：
{
"success": "failed",
"message": "Invalid username or password"
}
