android ListView 報錯 The specified child already has a parent

編輯:關於Android編程

今天遇到一個問題,在listviev中加入傳進來的布局,上下滑動時,報錯The specified child already has a parent。

先貼原始代碼:

		@Override
		public View getView(int position, View convertView, ViewGroup parent) {

			convertView = layoutInflater.inflate(R.layout.check_laizi_item_ll, null);
			RelativeLayout mRelativeLayout = (RelativeLayout) convertView.findViewById(R.id.clil_rl);
			List poker = mPokers.get(position);
			for (int j = 0; j < poker.size(); j++) {
				Poker card = poker.get(j);
				if (card.isLaiZi()) {
					card.getPokeImage().setImageDrawable(ImageUtil.getResDrawable(card.getBitpamResLaiZiID(), true));
				} else {
					card.getPokeImage().setImageDrawable(ImageUtil.getResDrawable(card.getBitpamResID(), true));
				}
				card.setId(position + 100);
				RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(mst.adjustXIgnoreDensity(45), mst.adjustYIgnoreDensity(61));
				params.topMargin = mst.adjustYIgnoreDensity(card_jiange);
				params.leftMargin = mst.adjustXIgnoreDensity(card_jiange * j);
				card.getInnerLayout().setBackgroundDrawable(ImageUtil.getResDrawable(R.drawable.poker_div, true));
				card.getInnerLayout().setVisibility(View.GONE);
				card.setClickable(false);
				card.setLayoutParams(params);
				mRelativeLayout.addView(card);
			}

			return convertView;
		}


再貼圖片:

原因是listview中我的Poker控件被多個convertView引用。

之前以為是我的convertView框架被復用的原因,因此我不對convertView進行服用,每次都創建一個convertView,可是也會報這個錯誤。

我想問題應該在position上,具體神馬情況不是我也不好解釋,只是感覺position與convertView的變動沒有及時同步吧<喎?/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+xMfO0r7NsNFjb252ZXJ0Vmlld9PDyv3X6bGjtObG8MC0o6zIu7rzuPm+3XBvc2l0aW9uyKXIoaOs1eLR+crHy/vDx82ssr08L3A+CjxwPjxicj4KPC9wPgo8cD7U2cz50N64xLrztPrC66O6PC9wPgo8cD48cHJlIGNsYXNzPQ=="brush:java;"> @Override public View getView(int position, View convertView, ViewGroup parent) { if(null==convertViews[position]){ convertView = layoutInflater.inflate(R.layout.check_laizi_item_ll, null); RelativeLayout mRelativeLayout = (RelativeLayout) convertView.findViewById(R.id.clil_rl); List poker = mPokers.get(position); for (int j = 0; j < poker.size(); j++) { Poker card = poker.get(j); if (card.isLaiZi()) { card.getPokeImage().setImageDrawable(ImageUtil.getResDrawable(card.getBitpamResLaiZiID(), true)); } else { card.getPokeImage().setImageDrawable(ImageUtil.getResDrawable(card.getBitpamResID(), true)); } card.setId(position + 100); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(mst.adjustXIgnoreDensity(45), mst.adjustYIgnoreDensity(61)); params.topMargin = mst.adjustYIgnoreDensity(card_jiange); params.leftMargin = mst.adjustXIgnoreDensity(card_jiange * j); card.getInnerLayout().setBackgroundDrawable(ImageUtil.getResDrawable(R.drawable.poker_div, true)); card.getInnerLayout().setVisibility(View.GONE); card.setClickable(false); card.setLayoutParams(params); mRelativeLayout.addView(card); convertViews[position]=convertView; } }else{ convertView=convertViews[position]; } Log.i("positionss", "position:"+position+" mPokers.size:"+mPokers.size()+" convertViews[position]:"+convertViews[position]); return convertView; }
