Проблема с выпуском окружения

Question

У меня проблема, я делаю приложение, и я подумал, что было бы неплохо иметь круглое меню, проблема в том, что у меня есть только значок выхода, остальные не могу, может, я что-то испортил в коде, не могли бы вы мне помочь?

        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
             RelativeLayout.LayoutParams.WRAP_CONTENT, 
             RelativeLayout.LayoutParams.WRAP_CONTENT); 
        lp.addRule(RelativeLayout.ABOVE, centerId); 
        lp.addRule(RIGHT_OF, centerId); 
        return lp; 
     } 

     private View prepareElementForCircle(View elem, int distX, int distY) { 
        RelativeLayout.LayoutParams lp = createNewRelativeLayoutParams(); 

        elem.measure(0, 0);

} 

Answer 1

Вы используете tv переменную каждый раз вы хотите, чтобы установить изображение вместо того, чтобы использовать тот, который вы хотите назначить в списке элементы (tv1, tv2 и т. д.)

Answer 2

попробуйте следующее:

class CircleView extends ViewGroup { 

    public CircleView(Context context) { 
     super(context); 
    } 

    @Override 
    protected void onLayout(boolean changed, int l, int t, int r, int b) { 
     int cnt = getChildCount(); 
     int x0 = r/2; 
     int y0 = b/2; 
     int radius = x0 * 2/3; 
     for (int i = 0; i < cnt; i++) { 
      double angle = i * 2 * Math.PI/cnt; 
      int x = (int) (x0 + radius * Math.sin(angle)); 
      int y = (int) (y0 - radius * Math.cos(angle)); 
      View child = getChildAt(i); 
      int w2 = child.getMeasuredWidth()/2; 
      int h2 = child.getMeasuredHeight()/2; 
      child.layout(x - w2, y - h2, x + w2, y + h2); 
     } 
    } 

    @Override 
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
     measureChildren(widthMeasureSpec, heightMeasureSpec); 
    } 
} 

испытание его следующим в OnCreate:

CircleView menu = new CircleView(this); 
    setContentView(menu); 
    for (int i = 0; i < 7; i++) { 
     Button b = new Button(this); 
     b.setText("#" + i); 
     menu.addView(b); 
    } 

посмотреть, как CircleView расширения ViewGroup короткий и простой
