Add a onItemClickListener for the AutoCompleteTextView instead of having it as a seperate function.
mTxtPhoneNo.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> av, View arg1, int index,
long arg3) {
Map<String, String> map = (Map<String, String>) av.getItemAtPosition(index);
String name = map.get("Name");
String number = map.get("Phone");
mTxtPhoneNo.setText(""+name+"<"+number+">");
}
});
or implement OnItemClickListener for your activity and set
mTxtPhoneNo.setOnItemClickListener(this);

The output you currently have seems to be the standard output of HashMap.toString method. So, you should make your own implementation of HashMap and override toString method.
回答3:
With an AutoCompeleteTextView its can be useful just to do as what @user936414 said, but it can makes problem if you have biggest app, even more with an multiAutoCompeleteTextView so it s recommended to overide toString methode by creating a "custom" HashMap like that :
public class ContactMap extends HashMap<String, String> {
/*
* (non-Javadoc)
*
* @see java.util.AbstractMap#toString()
*/
@Override
public String toString() {
if (isEmpty()) {
return "{}";
}
StringBuilder buffer = new StringBuilder(size() * 28);
Iterator<Map.Entry<String, String>> it = entrySet().iterator();
while (it.hasNext()) {
Map.Entry<String, String> entry = it.next();
Object key = entry.getKey();
if (key == "Name") {
Object value = entry.getValue();
buffer.append(value);
} else {
if (key == "Phone")
buffer.append("<");
Object value = entry.getValue();
if (value != this) {
buffer.append(value);
} else {
buffer.append("(this Map)");
}
if (key == "Phone")
buffer.append(">");
}
}
return buffer.toString();
}
}
and use it like this
// Using our custom HashMap
ContactMap NamePhoneType = new ContactMap();
