Closed 2 years ago.
I need to create a Recyclerview. For that I have created an cardview model to be displayed in a recyclerview. Even though i have given match parent to the layouts, the width of cardview is not fitting the parent. Its width is showing approximately up to half of the screen(not matching parent) Do anyone can support?.please advise better way to do this.

My Button is not working to get next activity by clicking on them

I implemented Bottom navigation bar in my project. When I declare and initialize buttons and then set onClickListener for them. The onclicklistener is not working fine without any error in logcat. I think its logical mistake that I'm unable to understand please see the code and guide me. (If you think the question is not according to community standards then I'm sorry in advance because I'm a beginner in java)
I searched a lot of questions related to this but nothing works for me.
Here is my main activity:
public class HomeActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
BottomNavigationView bottomNav = findViewById(R.id.bottom_navigation);
bottomNav.setOnNavigationItemSelectedListener(navListener);
//I added this if statement to keep the selected fragment when rotating the device
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new HomeFragment()).commit();
}
}
private BottomNavigationView.OnNavigationItemSelectedListener navListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment selectedFragment = null;
switch (item.getItemId()) {
case R.id.nav_home:
selectedFragment = new HomeFragment();
break;
case R.id.nav_notifications:
selectedFragment = new NotificationFragment();
break;
case R.id.nav_search:
selectedFragment = new SearchFragment();
break;
}
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
selectedFragment).commit();
return true;
}
};
}
Here is my First Fragment named HomeFragment:
public class HomeFragment extends Fragment implements View.OnClickListener {
Button btnFertilizers;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_home, container, false);
btnFertilizers = (Button)v.findViewById(R.id.btnFertilizers);
return inflater.inflate(R.layout.fragment_home, container, false);
}
#Override
public void onClick(View view) {
btnFertilizers.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(),Fertilizers.class);
getActivity().startActivity(intent);
}
});
}
Logcat shows zero error.
I believe that here is the problem area. This is because the click function is not working properly for Fertilizers.class:
#Override
public void onClick(View view) {
btnFertilizers.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(),Fertilizers.class);
getActivity().startActivity(intent);
}
});
}

How I should setOnClickListener to access my wanted activity?

Move this code into onCreateView.
btnFertilizers.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(),Fertilizers.class);
getActivity().startActivity(intent);
}
});
remove this
implements View.OnClickListener
remove this
#Override
public void onClick(View view) { }

You are calling another onClick lisnter inside the onclick method so it will no work.You should have to change the code like this:
#Override
public void onClick(View view) {
if (view.getId() == R.id.btnFertilizers) {
Intent intent = new Intent(getActivity(),Fertilizers.class);
getActivity().startActivity(intent);
}
Return v in your onCreateViewMethod .
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup
container, #Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_home, container, false);
btnFertilizers = (Button)v.findViewById(R.id.btnFertilizers);
return v;
}

How to align ImageView and TextView in Custom ListView

I have created a Custom Adapter to show ImageView and TextView together in ListView. But the ImageView is showing on the top of TextView in every row of Listview. I have attached a screenshot of app below:
Custom Adapter Class:
public class CustomeAdapter extends BaseAdapter {
private Context context;
private ListView listView;
private ArrayList<PlayersModel> playersModelArrayList;

Try to wrap Your text to separated LinearLayout with vertical orientation, and than put this LinearLayout with text on same level as ImageView inside another LinearLayout with orientation="horizontal"
But also, you should remember about render and measure performance.
You can read about this in https://android.jlelse.eu/constraint-layout-performance-870e5f238100
<LinearLayout
android:orientation="horizontal">
<ImageView
android:layout_width="0dp"
android:layout_weight="1" // try to read about this parameter more
/>
<LinearLayout
android:layout_width="0dp"
android:layout_weight="4"
android:orientation="vertical">
<TextView ... />
<TextView ... />
<TextView ... />
</LinearLayout>
</LinearLayout>

Try to create two linear layouts with orientation vertical under parent linear layout which has the horizontal orientation.
Set the second linear layout's width to match_parent and the image layout should be a fixed width value.

In order to simplify your xml, you should take a look to ConstraintLayout
To use it, make the import in your app gradle by adding implementation 'com.android.support.constraint:constraint-layout:1.1.3'
Then, refactor your xml as below:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/colorAccent" android:id="#+id/view"
tools:layout_editor_absoluteX="0dp" app:layout_constraintTop_toBottomOf="#+id/logoImageView"
android:layout_marginTop="8dp"/>
<ImageView
android:layout_width="64dp"
android:layout_height="64dp" tools:srcCompat="#tools:sample/avatars"
android:id="#+id/logoImageView"
app:layout_constraintStart_toStartOf="parent" android:layout_marginStart="8dp"
android:layout_marginTop="8dp" app:layout_constraintTop_toTopOf="parent"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:id="#+id/name"
tools:text="Name"
android:textAppearance="#style/TextAppearance.AppCompat" android:textStyle="bold"
android:layout_marginBottom="8dp"
app:layout_constraintBottom_toTopOf="#+id/descr" app:layout_constraintStart_toEndOf="#+id/logoImageView"
android:layout_marginStart="8dp"/>
<TextView
tools:text="Description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/descr" android:textColor="#313131"

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
public void onDetach() {
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" />

I had the same problem ...
the problem disappeared after changing my code in fragment
from
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
...
detailAdapter = new TitleAdapter(getChildFragmentManager(),getActivity());//remove this
...
}
on
#Override
public void onAttach(Context context) {
super.onAttach(context);
detailAdapter = new TitleAdapter(getActivity().getSupportFragmentManager (),getActivity());//add this
}
