Question

我有这段代码：

if (!errors.isEmpty()) {
        Context context = getApplicationContext();
        int duration = Toast.LENGTH_LONG;
        Toast toast = Toast.makeText(context, errors, duration);
        toast.show();
    } else {
        // Success! Cache the inputs and continue with registration.
        SharedPreferences settings = getSharedPreferences("settings", 0);
        SharedPreferences.Editor editor = settings.edit();
        editor.putString("name", name);
        editor.putString("email", email);
        editor.putString("password", password);

        Intent i = new Intent(view.getContext(),
                sendRegisterActivity.class);
        startActivityForResult(i, 0);
    }

现在，这是在public void sendRegistration(View view)范围内，点按一下按钮就会触发。每当我拿走“else”语句的最后3行时，它就有效。但是当我添加它时，我得到“无法找到源”。 sendRegisterActivity.java存在，但我仍然遇到错误。这就是sendRegisterActivity的外观：

public class sendRegisterActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.sendregister);
    }
}

sendregister.xml位于“layout”文件夹中，并且完全有效。

您是否已将sendRegisterActivity添加到清单中？

在活动变更时出错？
