 // Fare id calculation

     if(Source=="Delhi" && Dest=="Jaipur")

     }
     else  if(Source=="Delhi" && Dest=="Agra")
     {
         fareid=2;

推荐答案

只需使用AutoCompleteTextView方法的getText（）并调用的toString（）就可以了。

Just use the AutoCompleteTextView method getText() and call toString() on it.

// Fare id calculation
Source = source.getText().toString();
Dest = dest.getText().toString();

if (Source.equals("Delhi") && Dest.equals("Jaipur")) {
    fareid=1;
}
else if (Source.equals("Delhi") && Dest.equals("Agra")) {
    fareid=2;
}
else if (Source.equals("Delhi") && Dest.equals("Mumbai")) {
    fareid=3;
}

您应该记住，用户可以输入他们想要的一切到您的AutoCompleteTextView。如果您想在用户选择建议的项目之一执行的操作，添加 OnItemSelectedListener 与 dest.setOnItemSelectedListener（）。

You should keep in mind that users can enter everything they want into your AutoCompleteTextView. If you want to perform an action when the user chooses one of the suggested items, add an OnItemSelectedListener with dest.setOnItemSelectedListener().

还有一个在你的code你叫 dest.setAdapter（sadapter）而不是 source.setAdapter（sadapter）错误。

There is also an error in your code you call dest.setAdapter(sadapter) instead of source.setAdapter(sadapter).
