Hallo,
sorry habe erst vor kurzen angefangen Apps zu programmieren. Ich möchte, das die Url aus einer Textview (txt_ipAdresseLichteg) ausgelesen wird.
Zur Zeit steht die ip Adresse fest in der MailActivity.

String url5 = "(meine_ip_Adresse/)"; //NodeMCU ESP-ACA3E6

Wie kann ich diese aus der Textview auslesen? Kamm mir einer da weiter helfen? Danke

Die habe ich schon probiert, es klappt aber nicht.
String url5 = txt_ipAdresseLichteg .getText().toString();
String url5 = (txt_ipAdresseLichteg.toString());

Diskutiere mit!

Hallo pschmitz,
herzlich wilkommen hier im Forum :)



dafür brauchst du keine TextView im Layout sondern ein EditText.
Da kannst du deine Url dann reintippen und den String mit

myEditText.getText().toString();

auslesen.
Ich glaube du hast ausversehen nur ein TextView und keine EditText benutzt.

Hallo,
ich habe eine Activitylan, da speichere ich die ip Adressen in einer Textdatei. In der MailActivity lese ich die Textdatei aus und schreibe diese in einer Textview, damit ich sehe welche ip ich vergeben habe. Ich habe insgesamt 15 IP Adressen für die NodeMCU ESP-ACA3E6
Mit freundlichen Grüßen

wenn der Wert schon in der TextView steht, kannst du den da auch wieder auslesen, aber eigentlich nimmt man dafür die Datenquelle und keine View Fields.
Bist du dir sicher, dass es nicht geht?
Hast du mal den Debugger drüber laufen lassen und dir die Werte angeschaut?

Hallo der Wert wird mir richtig angezeigt. wenn ich die ip ändere wird das auch richtig angezeigt.
mit String url5 = "(http)meineIP"; funktioniert die App,
wenn ich die in String url5 = txt_ipAdresseLichteg.getText().toString(); schreibe.
Stürtz die app ab. :(

hiermit lese ich die serverip3.txt aus meinem Handy aus:

// IP Adresse laden
File dir = new File (path);
dir.mkdirs();

    // Iptext laden
    {
        File file  = new File(path +  "/serverip3.txt");
        String [] loadText = Load(file);
        String finalString = "";
        for (int i = 0; i < loadText.length; i++)
        {
            finalString += loadText[i] + System.getProperty("line.separator");
        }
        txt_ipAdresseLichteg.setText(finalString);
        editText_ip.setText(finalString);

    }
    //  IP Adresse laden

Das ist mein onClickListener:
btn_Licht1eg.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//String url5_rl = url5 + "Rel1"; // Damit funktioniert es!

       // String url5_rl = (txt_ipAdresseLichteg + "Rel1") ;
       // String url5_rl = (txt_ipAdresseLichteg + "Rel1");
       //String url5_rl = txt_ipAdresseLichteg.toString() + "Rel1";
        //String url5_rl = url5 + "Rel1";
        //textView_2.setText(txt_ipAdresseLichteg + "Rel1");
        SelectTask5 task = new SelectTask5(url5_rl);
        task.execute();
        updateStatus5();

    }

Sorry kann die ganze IP nicht schreiben:

Die IP brauch ich auch nicht,
aber den roten Log aus Logcat wenn die App abstürtzt wäre hilfreich.
Wo deklarierst du die TextView und machst en findViewById?

Du solltest dir Helper Klassen schreiben, damit dein Code übersichtlicher wird ;)

Warum musst du die IP aus dem Feld auslesen?

Warum nicht so?
(Pseudocode)

String myIp;
myIp = readFromFile(myFileName);
myTextField.setText(myIp)
myDevice.connect(myIp);

Wenn du es so machst, nimmst du direkt den aus dem File gelesenen String als IP und du musst das nicht aus dem Textfeld tun.

Aber das beantwortet meine Frage nach dem Log immer noch nicht...

Hallo Pascal,
ist meine erste App und d.h noch Anfänger.
ich denke, das mit Zeit und Erfahrung werde ich so was besser schreiben.
Ich lasse mir in der Activity die IP anzeigen, damit ich sehe an welche IP Adresse die Befehle gesendet werden und ich kann, über den Webbrowser (ipdaresse) auch die Ausgänge Ein/Aus schalten.
Logfile steht nicht nennenswertes:

Z 53:
String url5 = txt_ipAdresseLichteg .getText().toString();
Es kann sein das String url5 vorher ab gefrag wird und das aus lesen aus der Text.datei später erfolgt:
// IP Adresse laden
File dir = new File (path);
dir.mkdirs();

    // Iptext laden
    {
        File file  = new File(path +  "/serverip3.txt");
        String [] loadText = Load(file);
        String finalString = "";
        for (int i = 0; i < loadText.length; i++)
        {
            finalString += loadText[i] + System.getProperty("line.separator");
        }
        txt_ipAdresseLichteg.setText(finalString);

        // Test mit EditText
        editText_ip.setText(finalString);
    }
Hilfreich?

Das darf nicht sein.
Speicher dir den finalString der IP zusätzlich ab, dann musst du es nicht auslesen. Warum auch immer du das nicht machen willst...
