在过去的一天里，我一直在努力克服这个问题，但我没有成功。发生的事情是 - 我正在使用 Jsoup ( getElementsByClass) 获取某个类下的所有值，然后我正在运行一个 foreach 循环，最后，我使用runOnUiThread它来更新 UI 上的视图。
长话短说 - 出于某种原因，第一个元素没问题，但从第二个元素到第 10 个元素（有 10 个），它只使用第 10 个元素的值。当我取下 runOnUiThread 并将其用作常规函数（而不是在我需要的线程内）时，它可以完美运行并且不会跳过/复制任何元素。
所以，在这个很长的故事之后（对不起，我没有把它说短），这是我的代码：
counter = 1;
AssetManager assets = getAssets();
font = Typeface.createFromAsset(assets, "arial.ttf");
//Loading 10 gags
try {
Document doc = Jsoup.connect(url).get();
Elements content = doc.getElementsByClass("Gag-Content");
for(Element element : content) {
data = element.outerHtml();
if(data.indexOf("<iframe") == -1){
//Long ass random code here, in the end there are 2 variables: imageUrl & imageText
switch(counter){
case 1:
runOnUiThread(new Runnable() {
public void run() {
final TextView text1;
final ImageView image1;
text1 = (TextView)((Activity) context).findViewById(R.id.textView1);
text1.setText(imageText);
text1.setTypeface(font);
image1 = (ImageView)((Activity) context).findViewById(R.id.imageView1);
image1.setImageBitmap(getBitmapFromURL(imageUrl));
}
});
