Question

我在循环中调用draw类来绘制一堆行，但我只有一行这是抽奖类：

class DrawView extends View {
    Paint paint = new Paint();

    public DrawView(Context context) {
        super(context);

        paint.setColor(colorr[thecolore[0]]);
        paint.setStrokeWidth(10);
    }
    @Override
    public void onDraw(Canvas canvas) {

        canvas.drawLine(clickat[0], clickat[1], clickat[2], clickat[3], paint);
                            clickat[0] = -1;
                            clickat[1] = -1;
                            clickat[2] = -1;
                            clickat[3] = -1;
    }
}

（我将一些动态浮动传递给表clickat）我有这个循环：

for(int i=0; i<regenlinks[myposition].length;i+=8){

    if(regenlinks[myposition][i] !=-1 ){

        clickat[0] = X+30;
        clickat[1] = Y+30;
        clickat[2] = (float)regenlinks[myposition][i+3];
        clickat[3] = (float)regenlinks[myposition][i+4];
        thecolore[0] = (int)regenlinks[myposition][i+5];

        RelativeLayout mapView = (RelativeLayout) findViewById(R.id.rlayou);

        DrawView drawView = new DrawView(maps.this);
        drawView.setId((int)regenlinks[myposition][i+6]);
        mapView.addView(drawView);
    }
}

但是当循环结束时绘制的唯一一行是最后一行。有什么想法吗？
