我有一个包含字符串的数组。这就像：

String[] stops = {
        "Bangalore International Exhibition Center", "Jindal", "Manjunathnagar", "Nagasandra", "Dasarahalli", "Jalahalli", "Peenya Industry", "Peenya", "Yeswanthpur Industry", "Yeswanthpur", "Sandal Soap Factory", "Mahalaxmi", "Rajajinagar", "Kuvempu Road", "Srirampura", "Sampige Road", "Kempegowda Interchange", "Chikpet", "K R Market", "National College", "Lalbagh", "South End Circle", "Jayanagar", "R V Road Interchange", "Banashankari", "J P Nagar", "Puttenahalli", "Anjanapura Cross Road", "Krishna Leela Park", "Vajrahalli", "Thaighattapura", "Anjanapura/NICE Junction", "Kengeri", "R V College of Engineering", "Bangalore University Cross", "Rajarajeshwari Nagar", "Nayandahalli", "Mysore Road", "Deepanjali Nagar", "Attiguppe", "Vijayanagar", "Hosahall1i", "Magadi Road", "Sir M Vishweshwariah", "Vidhana Soudha", "M G Road Interchange", "Trinity", "Halasuru", "Indiranagar", "S V Road", "Baiyyappanahalli", "Jyotipura", "K R Puram", "Mahadevpura", "Garudacharpalya", "Doddanekkundi Induatrial State", "Vishweshwariah Industrial State", "Kundanahalli", "Vydhehi Hospital", "Satya Sai Medical Institute", "ITPB", "Kadugodi Industrial Area", "Ujjwal Vidhyalaya", "Whitefield", "Nagawara", "Arabic College", "Venkateshpura", "Tannery Town", "Pottery Town", "Cantonment Railway Station", "Shivajinagar", "Vellara Junction", "Langford Town", "Mico Bosch", "Dairy Circle", "Swagath Road Cross", "Jayadeva Hospital Interchange", "J P Nagar 4th Phase", "IIMB", "Hulimavu", "Gottigere", "Ragigudda Temple", "BTM Layout", "Silk Board", "HSR Layout", "Oxford College", "Muneshwara Nagar", "Chikkabegur", "Basapura Road", "Hosa Road", "Electronics City 1", "Electronics City 2", "Huskur Road", "Hebbagodi", "Bommasandra"
        };

现在我有一个TextView。我想知道，如何检查用户在我的 TextView 中输入的值是否来自该字符串数组。如果没有，它应该提示用户进行更正。

if(check(textView.getText.toString())){
//do somethingif true
}else{
//else
}

public boolean check(String text){
    for(String s: stops){
    if(s.equalsIngoreCase(text)){
    return true;
      }
    }
    return false;
    }

编写一个这样的函数来检查输入是否存在于您的字符串数组中，如果它返回 false，请要求用户进行更正，否则请执行您想要的任何操作。

  public boolean check(String input){
    for(String s: stops){
    if(s.equalsIngoreCase(input)){
    return true;
      }
    }
    return false;
    }

像AlertDialog一样使用它来查看警报是如何在 android 中完成的

尝试这个

    String s = obj_tv.getText().toString();

   String[] stops = {
        "Bangalore International Exhibition Center", "Jindal", "Manjunathnagar", "Nagasandra", "Dasarahalli", "Jalahalli", "Peenya Industry", "Peenya", "Yeswanthpur Industry", "Yeswanthpur", "Sandal Soap Factory", "Mahalaxmi", "Rajajinagar", "Kuvempu Road", "Srirampura", "Sampige Road", "Kempegowda Interchange", "Chikpet", "K R Market", "National College", "Lalbagh", "South End Circle", "Jayanagar", "R V Road Interchange", "Banashankari", "J P Nagar", "Puttenahalli", "Anjanapura Cross Road", "Krishna Leela Park", "Vajrahalli", "Thaighattapura", "Anjanapura/NICE Junction", "Kengeri", "R V College of Engineering", "Bangalore University Cross", "Rajarajeshwari Nagar", "Nayandahalli", "Mysore Road", "Deepanjali Nagar", "Attiguppe", "Vijayanagar", "Hosahall1i", "Magadi Road", "Sir M Vishweshwariah", "Vidhana Soudha", "M G Road Interchange", "Trinity", "Halasuru", "Indiranagar", "S V Road", "Baiyyappanahalli", "Jyotipura", "K R Puram", "Mahadevpura", "Garudacharpalya", "Doddanekkundi Induatrial State", "Vishweshwariah Industrial State", "Kundanahalli", "Vydhehi Hospital", "Satya Sai Medical Institute", "ITPB", "Kadugodi Industrial Area", "Ujjwal Vidhyalaya", "Whitefield", "Nagawara", "Arabic College", "Venkateshpura", "Tannery Town", "Pottery Town", "Cantonment Railway Station", "Shivajinagar", "Vellara Junction", "Langford Town", "Mico Bosch", "Dairy Circle", "Swagath Road Cross", "Jayadeva Hospital Interchange", "J P Nagar 4th Phase", "IIMB", "Hulimavu", "Gottigere", "Ragigudda Temple", "BTM Layout", "Silk Board", "HSR Layout", "Oxford College", "Muneshwara Nagar", "Chikkabegur", "Basapura Road", "Hosa Road", "Electronics City 1", "Electronics City 2", "Huskur Road", "Hebbagodi", "Bommasandra"
        };

    for(int i = 0; i < stops.length; i++)
    {
       if(stops[i].equalsIgnoreCase(s))
       {
        // do something 
       }
       else
       {
         // do something 
       }
