传递Intent不能得到extra(); [英] Passing Intent can't get extra();

问题描述

我无法在我的主要活动的网页中登录，我已将其传递给另一个活动，但我无法获得摘录.我该如何解决它

Hi i can't get logged in already in a web page at mine main activity i passed inten to another activity but i can't get an extract. How can i solve it

这是我的主要活动公共类 ViewActivity 扩展了 Activity {

this is mine main activity public class ViewActivity extends Activity {

private EditText mTextUserName;
private EditText mTextPassword;
public String user_name;
public String pass_word;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mTextUserName = (EditText) findViewById(R.id.textUserName);
    mTextPassword = (EditText) findViewById(R.id.textPassword);



    final Button mButtonLogin = (Button) findViewById(R.id.buttonLogin);
    mButtonLogin.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            user_name = mTextUserName.getText().toString();
            pass_word = mTextPassword.getText().toString();

            Intent goToNextActivity = new Intent(getApplicationContext(), ViewActivity.class);
            goToNextActivity.putExtra("username", user_name);
            goToNextActivity.putExtra("username", pass_word);

            startActivity(goToNextActivity);


        }
    });

在这里查看活动

private WebView webView;

public void onCreate(Bundle savedInstanceState) {


    super.onCreate(savedInstanceState);
    setContentView(R.layout.view);
    webView = (WebView) findViewById(R.id.webView);
    webView.getSettings().setUseWideViewPort(true);
    webView.setScrollbarFadingEnabled(false);
    webView.getSettings().setDefaultFontSize(20);
    webView.getSettings().setBuiltInZoomControls(true);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.setWebViewClient(new MyWebViewClient());




    webView.loadUrl("http://something.com");



}

private class MyWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        Intent goToNextActivity = new Intent(getApplicationContext(), MainActivity.class);
        goToNextActivity.getExtras();
        return true;

    }
}

它正在加载网页但未登录

it is loads a web page but not logged in

推荐答案

Intent extras = getIntent().getExtras();
String newString;
if(extras == null) {
    newString= null;
} else {
    newString= extras.getString("username");
}

对于用户名和密码这两个值，您提供相同的键值...请更改并尝试.

and for two values both username and password you are giving same key values...please change and try it.
