本文实例为大家分享了android自定义View实现五子棋的具体代码，供大家参考，具体内容如下

先说一下吧，android的自定义View就是自己实现一个类去继承View，实现其中的方法，这里面我最感兴趣的就是onDraw方法了，因为你要的样式都要在这里面进实现，看一下效果图吧：

大概就是介个样子的，长得丑不要紧，能用就行，毕竟只是简单的了解一下嘛！

*protected void onDraw(Canvas canvas) {
  super.onDraw(canvas);
  RectF rectF;
  for(int i= pandingx ; i < pandingx*7 ; i+=size){
    for(int z= pandingy ; z < pandingy*30 ; z+=size){
      rectF = new RectF(i , z , i+size , z +size);
      canvas.drawRoundRect(rectF , 1 ,1 ,paint);
    }
  }
  for(int i = 0 ; i <list.size() ; i++){
    int h = (int) list.get(i).get("x");
    int s = (int) list.get(i).get("y");
    if((int )list.get(i).get("flag") == 1) {
      rectF = new RectF(h - size/2, s - size/2, h + size/2, s + size/2);
      canvas.drawRoundRect(rectF, 50, 50, black);
    }else{
      rectF = new RectF(h - size/2, s - size/2, h + size/2, s + size/2);
      canvas.drawRoundRect(rectF, 50, 50, white);
    }
  }
  if(flag == 0) {
    rectF = new RectF(x - size / 2, y - size / 2, x + size / 2, y + size / 2);
    canvas.drawRoundRect(rectF, 50, 50, white);
  }else{
    rectF = new RectF(x - size / 2, y - size / 2, x + size / 2, y + size / 2);
    canvas.drawRoundRect(rectF, 50, 50, black);
  }
}

这里首先画出了一个棋盘，下的棋子就放在了一个ArrayList中，里面放的是一个个的map，分别放了x，y坐标还有他的属性（黑棋还是白棋），还有就是边界的处理问题，很简单我就不多说啦，毕竟是下棋的这个控件一定要是可以点的，不能只能看看那么简单。

public boolean onTouchEvent(MotionEvent event) {
  int action = event.getAction();
  switch (action) {
    case MotionEvent.ACTION_DOWN://按下
      x = pandingx+size;
      y = pandingy+size;
      xx = event.getX();
      yy = event.getY();
      invalidate();
      break;
    case MotionEvent.ACTION_MOVE://移动
      if(abs(event.getRawX()-xx)>=30){
        if(event.getRawX()>xx&&JudgeRight() == true){
          x += size;
          xx = event.getRawX();
          yy = event.getRawY();
        }else if(JudgeLeft() == true){
          x -= size;
          xx = event.getRawX();
          yy = event.getRawY();
        }
        invalidate();
      }
      if(abs(event.getRawY()-yy)>=30){
        if(event.getRawY()>yy&&JudgeButtom() == true){
          y += size;
          xx = event.getRawX();
          yy = event.getRawY();
        }else if(JudgeTop() == true){
          y -= size;
          xx = event.getRawX();
          yy = event.getRawY();
        }
        invalidate();
      }
      break;
    case MotionEvent.ACTION_UP://松开
      int i;
      for( i = 0 ; i < list.size() ; i++){
        if(x == (int)list.get(i).get("x")&&y == (int )list.get(i).get("y")){
          toast.repice();
          break;
        }
      }
      if(i == list.size()) {
        Map map = new HashMap();
        map.put("x", x);
        map.put("y", y);
        map.put("flag", flag);
        list.add(map);
        flag = (flag + 1) % 2;
        if(deal.setPiont((x-pandingx)/size , (y-pandingy)/size , flag+1)!=0){
          if(deal.setPiont((x-pandingx)/size , (y-pandingy)/size , flag+1) ==1){
            toast.winblack();
          }
          if(deal.setPiont((x-pandingx)/size , (y-pandingy)/size , flag+1) == 2){
            toast.winwhite();
          }
          list.clear();
          init();
        }
        x = -100;
        y = -100;
        invalidate();
      }
      break;
  }
  return true;
}
