奇怪的两个活动开始

Question

我的活动意图启动器出现问题。看来，当我运行这段代码时

Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setClass(this, contentScreen.class);
                startActivity(intent);
                finish();

在我的autoGO方法中，它运行两个活动，我知道这是因为我的logcat告诉我这个：

11-03 11:16:16.542: INFO/ActivityManager(58): Displayed activity three.three/.contentScreen: 2030 ms (total 3391 ms)
11-03 11:16:16.713: INFO/ActivityManager(58): Displayed activity three.three/.contentScreen: 1596 ms (total 1596 ms)

如果数据库中的特定值为true，我的流程基本上就是这个活动，它会自动运行autoGO，autoGO会在autoGO中启动一个新意图并带我到那个类。然而，我似乎在某处开始两项活动。结果我打开了两个相同类型的活动，但这是不需要的。这可能是什么原因？

这是autoGO方法：

public void autoGO(View arg1) throws IOException,
XmlPullParserException {

    EditText username = (EditText) findViewById(R.id.widget40);
    EditText password = (EditText) findViewById(R.id.widget37);

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    //gainString(remembered);
    setUserPass();
    System.out.println(Compare[1]);
    System.out.println(Compare[2]);
    request.addProperty("User", Compare[1]);
    request.addProperty("Password", Compare[2]);
    autoSign = false;
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(request);
    AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL);
    httpTransport.debug = true;
    httpTransport.call(SOAP_ACTION, envelope); // send request
    SoapObject result = (SoapObject) envelope.getResponse(); // get
    System.out.println(result);

    int Conversion = Integer.parseInt(result.getProperty(0).toString());
    System.out.println(Conversion);
    if (Conversion > 0) {

        try{

            sqlDB=openOrCreateDatabase(DBNAME1,Context.MODE_PRIVATE,null);
            System.out.println("open or create database");
            //sqlDB.execSQL("UPDATE " + Table1 + " SET NAME = '" + sUserName + "' WHERE NAME = '" + remembered[1] + "'");
            System.out.println("URL updated");
            //sqlDB.execSQL("UPDATE " + Table1 + " SET PASSWORD = '" + sPassword + "' WHERE PASSWORD = '" + remembered[2]+ "'");
            sqlDB.execSQL("UPDATE " + Table1 + " SET URL = '" + "http://" + result.getProperty(2).toString()+ "'");
            System.out.println("HERE IS THE NEW URL " + "http://" + result.getProperty(2).toString());

            contentScreen co = new contentScreen();
            co.signAuto(true);

            Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setClass(this, contentScreen.class);
                startActivity(intent);
                finish();
        }


             catch (Exception e1) {
                // TODO Auto-generated catch block
                 System.out.println("Problem "+ e1.getMessage());
                e1.printStackTrace();
            }
            finally
            {
                sqlDB.close();

            }

    } else {
        username.setTextSize(10);
        username.setText("Invalid username or passcode!");
    }
}

Answer 1

我认为这是因为setRequestedOrientation：默认情况下，android会在方向更改时重新创建活动。您可以在应用程序清单文件中为活动指定特定方向。

Answer 2

我无法相信自己有多愚蠢。我只是看了几个小时的代码并错过了这个。

for (int i = 0; i < tickBoxes.length; i++) {
    if (tickBoxes[1]) {
        saveBox.setChecked(true);

        if(!tickBoxes[0]){

        try {
            //gainString(remembered);

            setUserPass();

            username.setText(remembered[1]);
            System.out.println(remembered[1]);
            password.setText(remembered[2]);

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        }

        // SET THE TEXT HERE IF NEEDED
    }
    if (tickBoxes[0]) {
        checkBox.setChecked(true);
        try {
            autoSign = true;
            System.out.println(autoSign);
            autoGO(arg3);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

条件为真，并且处于for循环中，它会运行两次。这是一个小学生的错误 - 好的-_-
