Fix или Заменить код обработчика для автоматического случайного

-4

мне нужна помощь в здесь, поэтому я хочу использовать обработчик для автоматического Random мой список случай каждый 2 второйFix или Заменить код обработчика для автоматического случайного

полный код, как это

public class play extends Activity implements View.OnClickListener{ 

int number; 
Button button1, button2, button3, button4, button5, button6, button7, button8, button9, button10, button11, button12, button13, button14, button15, button16; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
    WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    setContentView(R.layout.play); 


    button1 = (Button)findViewById(R.id.button1);

//i had use setOnClickListener(This) to make all of button do same logic in one method

     ms=ms-20; //20ms faster 
     mHandler.postDelayed((Runnable) this, ms); 
     mHandler.postDelayed(mUpdateTimeTask, 100); 

} 

}

После того как я искать то, что проблема теперь я нашел, что это правда, сила близко причина по методу Handler:

final Handler mHandler = new Handler(); 
    int ms=2000; //2secs. 



    final Runnable mUpdateTimeTask = new Runnable() { 
    public void run() { 

     //Do random logic 

       } 

     }; 

    ms=ms-20; //20ms faster 
    mHandler.postDelayed((Runnable) this, ms); 
    mHandler.postDelayed(mUpdateTimeTask, 100); 

} 
}

я прошу прощения, если вы безумием взгляд на мой код, потому что я была нужна помощь с людьми больше expe чтобы исправить текущую проблему, или у кого-нибудь есть образец кода для замены метода обработчика?

Спасибо заранее.

Массивов и петли были сделаны по этой причине ... –

Define a Runnable: не действительна Java. Либо удалите его, либо прокомментируйте.

Далее, чтобы очистить код, сделать что-то вроде этого:

Button[] buttons = new Button[]{ button1, button2, ... button15, button16 }; 
// fill in the other buttons above 

Random generator = new Random(); 
number = generator.nextInt(16); 

for(int i=0; i<buttons.length; i++) { 
    if(i == number) 
     buttons[i].setVisibility(View.VISIBLE); 
    else 
     buttons[i].setVisibility(View.INVISIBLE); 
}

Наконец, вы, вероятно, получите ClassCastException когда вы делаете это:

mHandler.postDelayed((Runnable) this, ms);

this в этом контексте вероятно, Activity, что не является Runnable. Вместо этого просто выполните:

mHandler.postDelayed(mUpdateTimeTask, ms);

и удалите вторую линию. Вы можете также разместить работоспособный себя обработчик в методе run():

final Handler mHandler = new Handler(); 
int ms=2000; 

final Runnable mUpdateTimeTask = new Runnable() { 
    public void run() { 
     //Do random logic 

     ms -= 20; 
     if(ms > 0) // stop when delay is less than 0. 
      mHandler.postDelayed(this, ms); 
    } 

}; 


// run this in a method. 
mHandler.postDelayed(mUpdateTimeTask, ms); // post the first

Этого кода он работал человек Спасибо в! но могу ли я сделать, чтобы ms> 0 задержка не прекращалась случайным образом? – RichFounders
