Word Scrambler, Android Studio

Question

Ich versuche, auf eine Schaltfläche "neues Wort" zu klicken, die ein hart codiertes verschlüsseltes Wort generiert. Entweder (Fahrrad, Ball, Clown, Apfel). Meine App läuft, aber wenn ich auf den Knopf klicke passiert nichts. Ich weiß nicht, ob es ein OnClicklistener oder was fehlt. Jede Kodierungshilfe wäre willkommen. Meine Rechtschreibprüfung soll ein "ja du bist richtig" oder "versuche es noch einmal" erzeugen.

Answer 1

Sie müssen die Schaltfläche (in der XML-Layout)

android:onClick="submitting" 

hinzufügen

versuchen auch, eine neue Klasse zu erstellen:

import java.util.ArrayList; 
import java.util.Collections; 
import java.util.Random; 


public class WordScramble2 { 

static String pickword; 


public WordScramble2() 
{ 
    Random rand = new Random(); 
    String[] words = {"clown", "ball", "bike", "apple"}; 
    int randint = rand.nextInt(words.length); 
    pickword = words[randint]; 

} 



    public static String scramble(String ch) 
{ 
    ArrayList<Character> array = new ArrayList<Character>(); 
    String Scrambled = ""; 
    for (int b = 0; b < ch.length() ; b++){ 
     array.add(ch.charAt(b)); 
    } 
    Collections.shuffle(array); 
    for (int k = 0; k < array.size(); k++) 
    { 
     Scrambled += array.get(k); 
    } 
    return Scrambled; 
}} 

und die Taste und Haupttätigkeit ändern:

public void submitting(View view) { 
int randint = random.nextInt(words.length); 
answerField = words[randint]; 
WordScramble2 wrdScr2 = new WordScramble2(); 
inputField = wrdScr2.scramble(answerField); 
scrammbleField.setText(inputField); 
userAns.setText(""); 

}
