在 LinearLayout 中添加多个 TextView 会导致 stackOverflowError

Question

我需要将多个 TextViews 添加到一个 LinearLayout。

但是代码正在创建某种循环依赖性，这导致 WhosebugError。

 LinearLayout tagsLayout;
 tagsLayout = (LinearLayout) rootView.findViewById(R.id.pager_item_tags);

  if (!tagsArrayList.isEmpty()) {
      TextView tagTitle = new TextView(context);
      tagTitle.setText("Tags: ");
      tagsLayout.addView(tagTitle, 0);
      TextView tagsTextView = new TextView(context);
      tagsTextView.setGravity(TextView.TEXT_ALIGNMENT_CENTER);
      tagsTextView.setBackgroundResource(R.drawable.bg_tag);                            
      tagsTextView.setTextColor(context.getResources().getColor(R.color.ColorWhite));
      tagsTextView.setPadding(4, 0, 4, 0);

      for (Tags tags : tagsArrayList) {
          tagsTextView.setText(tags.getName());

         /*generating some kind of cyclic dependency*/

        if (tagsTextView.getParent() != null) {
            ((ViewGroup) tagsTextView.getParent()).removeView(tagsTextView);
        }

        tagsLayout.addView(tagsTextView);
     }

  }

如果我不使用getParent().removeView() 我得到 java.lang.IllegalStateException you must call removeView() on the child's parent first. 我需要显示数量不同的 tags，所以我无法使用 xml 来达到预期的结果。

感谢您的帮助。

您只是在创建一个 TextView 多次更改文本，然后仅将一个 TextxView 添加到父布局。

创建它的所有代码都应该在您的循环中

 for (Tags tags : tagsArrayList) {
    // create it here and add it
}

我不确定这是否会解决异常，但我认为这是您想要做的。

不会更改的属性可以在循环外声明一次，然后在创建循环时在循环内设置。

例如

int textColor = context.getResources().getColor(R.color.ColorWhite)

然后，在你的循环中

tagsTextView.setTextColor(textColor);
