দয়া করে এটি নীচে আমার কোড এবং আমি নীচে ত্রুটি বার্তাগুলি আটকে দিচ্ছি: আমি setOnItemClickListener
স্পিনারের উপর ব্যবহার করার চেষ্টা করছি , এটি কি অনুমোদিত?
@Override
public void onItemClick(AdapterView<?> arg0, View v, int index, long arg3) {
if (quantity[index]=="Meter" ){
s1="Meter";
Toast.makeText(v.getContext(), "convert from meter",Toast.LENGTH_SHORT).show();
}
}
});
convertto.setOnItemClickListener(new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> arg, View v1, int index1, long arg4)
{
if ((quantity[index1]=="Meter") && (s1.equalsIgnoreCase("Meter")))
{
Toast.makeText(v1.getContext(), " to meter",Toast.LENGTH_SHORT).show();
var2=var1;
lresult.setText("" + var2);
}
}
});
}
}
এবং এখানে ত্রুটি আছে
