Problem in Android application:
Solution: check code for set and get selection

// Spinner _spin1 contain only 49 items
// you can set max 48 ( range 0 - 48)
// 50 is IndexOutOfBoundsException
_spin1.setSelection(50);
You have to add constructor!
public static class YourFragment extends Fragment {
//you have to add constructor!!!!!
public YourFragment(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_main, container, false);
return view;
}
}
R.string.app_name to String example.
MyActivity.java
res/values/string.xml
MyActivity.java
Resources res = getResources();
String sText = res.getString(R.string.app_name);
res/values/string.xml
<resources>
<string name="app_name">My app name</string>
</resources>
Map TreeMap add key value pair get find pair by key Java Android example.
MainClass.java
MainClass.java
import java.util.Map;
import java.util.TreeMap;
public class MainClass {
public static void main(String[] arg) {
// english;germany dictionary
String[] arrayOfString = { "one;eine", "two;zwei", "three;drei" };
Map<String, String> map = new TreeMap<String, String>();
for(String s: arrayOfString){
String[] array = s.split(";");
String sKey ="", sValue="";
if(array.length > 1){
sKey = array[0]; sValue = array[1];
map.put(sKey, sValue);
}
}
// check if key exists
if( map.containsKey("two")){
System.out.print("two = " + map.get("two"));
}
}
}
/*
