Konnte Methode für android nicht ausführen: onClick (TextView.setText)

Question

Und das ist mein MainActivity Code (ye, es schlecht, aber ich lerne nur das):

public class MainActivity extends AppCompatActivity { 
private ImageButton settingsButon; 
private ImageButton infoButon; 
private SharedPreferences sp; 
TextView textView; 
private int min; 
private int max; 
private RelativeLayout relativeLayout; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    settingsButon = (ImageButton)findViewById(R.id.settingsButton); 
    infoButon = (ImageButton)findViewById(R.id.infoButton); 
    relativeLayout = (RelativeLayout)findViewById(R.id.relLayout); 
    textView = (TextView)findViewById(R.id.randomedView) ; 
    sp = PreferenceManager.getDefaultSharedPreferences(getApplicationContext()); 
    // textView.setPaintFlags(textView.getPaintFlags() | Paint.SUBPIXEL_TEXT_FLAG); 


} 

@Override 
protected void onResume() { 
    super.onResume(); 
    boolean darkTheme = sp.getBoolean("darkTheme",false); 
    if(darkTheme){ 
     relativeLayout.setBackgroundColor(getResources().getColor(R.color.colorPrimaryDark)); 
     settingsButon.setImageResource(R.drawable.settings_white); 
     infoButon.setImageResource(R.drawable.information_white); 
    } 
    else { 
     relativeLayout.setBackgroundColor(getResources().getColor(R.color.colorPrimary)); 
     settingsButon.setImageResource(R.drawable.settings_black); 
     infoButon.setImageResource(R.drawable.information_black); 
    } 

    min = Integer.parseInt(sp.getString("minNumber", "1")); 
    max = Integer.parseInt(sp.getString("maxNumber", "100")); 
} 

public void settingsClick(View view) { 
    Intent intent = new Intent(this,Preferences.class); 
    startActivity(intent); 
} 


public void onClick(View view) { 
     Randomizer randomizer = new Randomizer(); 
     int randomed = randomizer.randomNext(min,max); 
     System.out.println(randomed); 
     textView.setText(randomed); 

} 

So hält es Arbeit in diesem Teil:

Ich habe diese TextView initialisieren und Android: onClick, aber ich denke, ich habe etwas falsch gemacht. Wenn ich nur string schreibe, funktioniert es gut, aber wenn ich klicke (tippe), funktioniert die App nicht mehr P.S. Sorry für mein Englisch

Answer 1

Sie den Aufruf der textView.setText(String s) Methode mit einem Parameter, der kein String ist. Bitte konvertieren Sie einfach Ihr Argument randomed in einen String, wenn Sie textView.setText(String s) entweder mit textView.setText(new String(randomed)) oder textView.setText(""+randomed) aufrufen.

Answer 2

textView.setText(randomed+"");
