How to find the ID of a dynamic UI element in android

How to find the ID of a dynamic UI element in android - java

I can make the dynamic UI without problems, but I don't know how to access the view with findviewbyid (R.id._____) I don't know what to put in the blank.
.java code
public class newList extends AppCompatActivity {
Button btnAddItem;
RelativeLayout layout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new_list);
// allows the creation of dynamic rows
btnAddItem = (Button) findViewById(R.id.addItem);
btnAddItem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
LayoutInflater inflater = getLayoutInflater();
ViewGroup parent = (ViewGroup) findViewById(R.id.linearVert);
inflater.inflate(R.layout.rows, parent);
}
});
}
}

There will be no unique R.id value at the activity level. For example, suppose the user taps the button 10 times, so you inflate the R.layout.rows layout 10 times. As a result, there will be 10 R.id.linearHor widgets, 10 R.id.itemPrice widgets, and so on.
Always call findViewById() on something that is guaranteed to give you a unique result. In this case — as with ListView, GridView, RecyclerView, etc. — you need to use other approaches to find the correct row View, then call findViewById() on that View to get at its child widgets.

Why do i always see the last id in View.OnClickListener?

Why do I always see the last id no matter which text I click?
I would like to see the right fragment displayed in the layout that i created according to the relevant text clicked. I always see the 'alternatives' fragment.
I understood that tags could be helped, but I could not figure out how to use them.
In addition, I tried to use diffrent versions of FragmentManager and FragmentTransaction and even to remove the switch and call each setOnClickListener of textview separately but nothing helped.
This is my Activity file:
IngredientsFragment ingredientsFragment;
FavouritesFragment favouritesFragment;
FeedbacksFragment feedbacksFragment;
Write_Feedback_Fragment writeFeedbackFragment;
AlternativesFragment alternativesFragment;
TextView ingredients;
TextView favourites;
TextView feedbacks;
TextView alternatives;
TextView writeFeedback;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_product_details);
window=this.getWindow();
window.setStatusBarColor(this.getResources().getColor(R.color.colorPrimaryDark));
ingredients= (TextView) findViewById(R.id.ingredients_option);
favourites= (TextView) findViewById(R.id.favorites_option);
feedbacks= (TextView) findViewById(R.id.watch_feedback_option);
writeFeedback= (TextView) findViewById(R.id.add_feedback_option);
alternatives= (TextView) findViewById(R.id.alternatives_option);
ingredients.setOnClickListener(this);
favourites.setOnClickListener(this);
feedbacks.setOnClickListener(this);
writeFeedback.setOnClickListener(this);
alternatives.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.ingredients_option:
ingredientsFragment= new IngredientsFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,ingredientsFragment).commit();
break;
case R.id.favorites_option:
favouritesFragment= new FavouritesFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,favouritesFragment).commit();
break;
case R.id.watch_feedback_option:
feedbacksFragment= new FeedbacksFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,feedbacksFragment).commit();
break;
case R.id.add_feedback_option:
writeFeedbackFragment= new Write_Feedback_Fragment();
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,writeFeedbackFragment).commit();
break;
case R.id.alternatives_option:

getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,alternativesFragment).commit();

Your code should work like that. The problem is your layout. See the textviews in your FrameLayout. Your defining a paddingLeft and layout_width so, that your textview alternatives_option is overlaying all the other textviews. Thats why in the onclick you always get the id of that view.
I suggest doing a tutorial about XML layout.
<TextView
android:id="#+id/alternatives_option"
android:layout_width="408dp"
android:layout_height="90dp"
android:layout_gravity="left"
android:drawableTop="#drawable/ic_alternatives"
android:paddingLeft="320dp"
android:text="Alternatives" />

Custom Dialog is not opening on click in fragment?

I build my own custom Dialogbut its not opening when i am clicking on ImageView. I also checked by putting break point Dialog is coming null how to rectify it. I want to shift TextView of id unread_count to the right of parent . How can I do this ?
If I set android:layout_alignParentRight="true" then I have the following picture :
<?xml version="1.0" encoding="utf-8"?>

Java code
private ImageView dialogBox;
Dialog customDialog;
customDialog = new Dialog(getActivity());
dialogBox = (ImageView) view.findViewById(R.id.dialogBox);
dialogBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
showDialog();
}
});
private void showDialog() {
customDialog.setContentView(R.layout.dialog_info);
}

You can try this way, you have to find dialog views using dialog.findViewById
Dialog dialog = new Dialog(mActivity);
dialog.setContentView(R.layout.dialog_info);
//dialog.setCancelable(false); //set Cancelable
ImageView dialogBox = (ImageView) dialog.findViewById(R.id.imgViewID);
dialogBox.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
//for big size dialog
/* Window window = dialog.getWindow();
window.setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);*/
I check you dialog_info.xml code
You need to improve your design code, you don't need to take static height and weight
I update your layout code here
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

You forgot to call show method on the custom dialog. Change your code to
private void showDialog() {
customDialog.setContentView(R.layout.dialog_info);
// Add this line
customDialog.show();
}

#BindView(R.id.dialogEndCount_buttonsLay)
LinearLayout dialogEndCount_buttonsLay;
private Window window;
private Activity activity;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_update);
//Initialize
ButterKnife.bind(this);
activity = this;
window = activity.getWindow();
//Set color to statusBar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
window.setStatusBarColor(getResources().getColor(R.color.tabHomeColor));
}
//Set dynamically weight
dialogEndCount_buttonsLay.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT));
}
}
How can I fix this problem?

If you want set dynamically weightSum just use this code :
dialogEndCount_buttonsLay.setWeightSum(3f);
i hope help you

You're mixing LinearLayout and RelativeLayout. Change your layout to use a LinearLayout then weight is an available property on your LayoutParams.
val params = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT)
params.weight = 1f

Android fragment oncreateview is called but view is not inflated and there are no errors

So I've done this a fair amount of times but I'm truly stumped this time. My fragment is called from my activity with no problems and although the onCreateView() is called, nothing at all shows up, still no errors. I've spent a couple hours looking for similar questions here with no luck.
Here is my swapFragment() method that calls my fragment:
private void swapFragment() {
GenresFragment genresFragment = new GenresFragment();
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.flgenre, genresFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
Here is my GenresFragment.java:
public class GenresFragment extends Fragment {
// TODO: Customize parameter argument names
private static final String ARG_COLUMN_COUNT = "column-count";
// TODO: Customize parameters
private int mColumnCount = 1;
private OnListFragmentInteractionListener mListener;
private DatabaseReference mPostReference;
String userID = FirebaseAuth.getInstance().getCurrentUser().getUid();
private ArrayList<String> genreList = new ArrayList<>();
private MyGenreRecyclerViewAdapter myGenreRecyclerViewAdapter;
/**
* Mandatory empty constructor for the fragment manager to instantiate the
* fragment (e.g. upon screen orientation changes).
*/
public GenresFragment() {
}
// TODO: Customize parameter initialization
#SuppressWarnings("unused")
public static GenresFragment newInstance(int columnCount) {
GenresFragment fragment = new GenresFragment();
Bundle args = new Bundle();
args.putInt(ARG_COLUMN_COUNT, columnCount);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
mColumnCount = getArguments().getInt(ARG_COLUMN_COUNT);
}
}
#Override
public View onCreateView(LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_mini_add, container, false);
if (rootView == null){
Log.e("TEST1", "Is Null");
}else {
Log.e("TEST2", "Not Null");
}
return rootView;
}
public void failure(){
Toast.makeText(getActivity(),"Something Went Wrong",Toast.LENGTH_LONG).show();
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnListFragmentInteractionListener) {
mListener = (OnListFragmentInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnListFragmentInteractionListener");
}
}
#Override

super.onDetach();
mListener = null;

I finally figured out the answer, all I had to do was change my root element(linear layout) to frame layout and it worked. Hope this helps someone. Thanks to everyone for their suggestions.

Try to modify you swapFragment() with below code by replacing replace() with add()
private void swapFragment() {
GenresFragment genresFragment = new GenresFragment();
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.flgenre, genresFragment);
fragmentTransaction.commit();
}

Other people already asked for the activity xml, but for what I could see right now, it looks like you are inflating the fragment's layout in a FrameLayout that is contained in it's own layout.
Meaning, the container you are inflating into should not be in the fragment's layout, but in the activity's layout.
Unless I understood it wrong, you should not have the with id/flgenre in fragment_mini_add.xml but in Activity_main.xml (or whatever the layout of the activity is)
Edit: in both activity and the fragment_mini_add.xml there is a layout with the same id you are trying to inflate into. I'm not sure if this causes the problem, but I imagine this could be the cause.

You should remove android:id="#+id/flgenre" in the first xml tag from your activity xml and fragment_mini_add.xml.
replace tools:context="com.nocrat.fanti.ProfileActivity" with tools:context="com.nocrat.fanti.GenresFragment" in fragment_mini_add.xml.
then, add this code to your activity xml to contain the fragment
<FrameLayout
android:id="#+id/flgenre"
android:layout_width="match_parent"
android:layout_height="match_parent" />

why cant I Update text dynamically in fragments?

How can i change text and images dynamically also i've three more fragments that use same layout(pager_layout) also can i add different intents or not?

You have to set text in your text view inside onViewCreated() method and not in onCreateView() in your fragment class:
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.pager_layout, container, false);
return view;
}
TextView tv;
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
tv = (TextView) view.findViewById(R.id.textDes);
tv.setText("text to set dynamically");
...
}
