i have a specific issue. Im creating a App which allows me to display recepts of certain dishes. I designed a custom Adapter which contains a TextView and RatingBar. So in my other Activity(ViewDatabase) i retrieve the dish-name from a JSON-File (method is called : showData) and display it on a ListView which gets the custom adapter.
My problem is now that dont know why i can only select either the name of my dish ( so the textview of my adapter ) or the ratingbar ( is also in my adapter).
I tried to put in the method : myListView.setItemsCanFocus(true); but still doesnt work.
Is i didnt implement a clicklistener to my text in the Adapter? I tried to implement one.I need a explicit intent which swaps the Activity but i cant go from a Adapterclass to a other class in a intent.
In the ViewDatabse- Class is onItemClick my method for changing the activty if i click the text.
Here is my code :
- Adapter:
a)
public UserInformationAdapter(Context context, List<UserInformation> objects) {
super(context, R.layout.rating_item, objects);
this.context = context;
table = objects;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = inflater.inflate(R.layout.rating_item, null);
}
TextView name = (TextView) v.findViewById(R.id.hauptgerichte);
RatingBar ratingBar = (RatingBar) v.findViewById(R.id.rate_bar);
UserInformation userInformation = table.get(position);
ratingBar.setOnRatingBarChangeListener(onRatingChangedListener(position));
ratingBar.setTag(position);
ratingBar.setRating(getItem(position).getRatingStar());
name.setText(userInformation.getName());
name.setTag(position);
return v;
}
private RatingBar.OnRatingBarChangeListener onRatingChangedListener(final int position) {
return new RatingBar.OnRatingBarChangeListener() {
@Override
public void onRatingChanged(RatingBar ratingBar, float v, boolean b) {
UserInformation item = getItem(position);
assert item != null;
item.setRatingStar(v);
Log.i("Adapter", "star: " + v);
}
};
}
}
This is the Item (for name and ratingbar):
public class UserInformation {
private String name;
private float ratingStar;
public UserInformation(){
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
void setRatingStar(float ratingStar) {
this.ratingStar = ratingStar;
}
float getRatingStar() {
return 0;
}
@Override
public String toString(){
return name;
}
}
This is the Activity which retrieves the Name:
- Activity:
public class ViewDatabase extends AppCompatActivity {
private static final String TAG = "ViewDatabase";
private FirebaseDatabase mFirebaseDatabase;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
private DatabaseReference myRef;
private String userID;
private ArrayList<String> array;
private final List<UserInformation> arr = new ArrayList<>();
private UserInformationAdapter adapter2;
private ListView mListView;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view_database_layout);
array = new ArrayList<>();
mListView = (ListView) findViewById(R.id.list_karnivoure);
mListView.setItemsCanFocus(true);
mAuth = FirebaseAuth.getInstance();
mFirebaseDatabase = FirebaseDatabase.getInstance();
myRef = mFirebaseDatabase.getReference();
FirebaseUser user = mAuth.getCurrentUser();
userID = user.getUid();
myRef.child("shakes").addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
// This method is called once with the initial value and again
// whenever data at this location is updated.
showData(dataSnapshot);
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
private void showData(DataSnapshot dataSnapshot) {
Iterable<DataSnapshot> children = dataSnapshot.getChildren();
for (DataSnapshot child: children){
UserInformation uInfo = child.getValue(UserInformation.class);
arr.add(uInfo);
adapter2 = new UserInformationAdapter(ViewDatabase.this, arr);
mListView.setAdapter(adapter2);
mListView.setItemsCanFocus(true);
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
mListView.setItemsCanFocus(true);
Object listItem = mListView.getItemAtPosition(position);
Intent i = new Intent(ViewDatabase.this,KarnivoureInput.class);
i.putExtra("name", listItem.toString());
startActivity(i);
}
});
}
