我有尋呼機適配器初始化片段列表。問題是片段加載非常緩慢。它有幾秒鐘的延遲，比開始執行加載數據。 我在的AsyncTask doInBackground（分析來自URL的數據），並與UI中的AsyncTask onPosteExecute（）工作尋呼機適配器中的片段加載非常緩慢（延遲幾秒鐘比加載數據）
這裏是我的片段：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
readBundle(getArguments());
v = inflater.inflate(R.layout.fragment_fragment1, container, false);
new asyncTekstovi().execute(result);
return v;
}
public class asyncTekstovi extends AsyncTask<String, ArrayList<String>, ArrayList<String>> {
String result;
@Override
protected ArrayList<String> doInBackground(String... params)
{
try {
result = Ion.with(getActivity().getApplicationContext())
.load(FragmentNewsReader.this.result)
.asString()
.get();
} catch (Exception e){
e.printStackTrace();
}
String pasusUTekstu="";
if (result != null){
String htmlStringTekst=result.substring(result.indexOf("<!-- BEGIN .shortcode-content -->"), result.length());
int startPositionTekst=htmlStringTekst.indexOf("<div class=\"shortcode-content\">");
int endPositionTekst=startPositionTekst+"<div class=\"shortcode-content\">".length();
while(htmlStringTekst.substring(startPositionTekst,endPositionTekst).indexOf("<!-- END .shortcode-content -->")<0){
endPositionTekst++;
}
htmlStringTekst=htmlStringTekst.substring(startPositionTekst,endPositionTekst);
//System.out.println("vladica:"+htmlStringTekst.length()+htmlStringTekst);
int poc1;
int kraj1;
while((poc1=htmlStringTekst.indexOf("<div id"))>=0){
//System.out.println("poc1="+poc1);
kraj1=poc1+"<div id".length();
while(htmlStringTekst.substring(poc1,kraj1).indexOf(">")<0){
//System.out.println("seckanje:"+htmlStringTekst.substring(poc1,kraj1));
kraj1++;
}

你可以顯示'readBundle（）'的代碼嗎？ –
它只是從url綁定到url： private void readBundle（Bundle bundle）if（bundle！= null）{ result = bundle.getString（「name」）; } } – smiljka
