Text doen't appear after speech in adroid studio

Today i am posting my first question here in stackoverflow.
My app's subject is speech to text application all the app is working but the text doen't appear in its zone after saying the speech. So i am here asking you all for help.
Belong my xml file :
<?xml version="1.0" encoding="utf-8"?>

If I understand correctly, you are trying to figure out how to display the RecyclerView list of items, and when an item is clicked, show its data in a TextView below. Please correct me if I am wrong.
For the first step, you are close. All you need to do is instantiate a new layout manager and an instance of your adapter class, and pass them to your RecyclerView.
Add this to your CustomDialog class:
public void callDialog() {
...
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(context);
writing_dialog_recy.setLayoutManager(layoutManager);
// I'm assumming you are passing a list of data here
WritingNovelAdapter adapter = new WritingNovelAdapter(context, dataList);
writing_dialog_recy.setAdapter(adapter);
...
As for showing the text in the textView, you have a few different ways to implement this. Its hard to say without seeing the rest of the related code, but I would recommend implementing a callback interface and calling the method from your ViewHolder, like so:
Define the interface in your Adapter class
public interface CallbackInterface {
void showText(String text);
}
Implement a callback interface in your CustomDialog class and implement the setText method, which is where you will set the text in the TextView. This will require that you have an instance of the TextView that you want to show that text in, meaning you must call this somewhere: TextView textView = findViewById(R.id.textView8);
class CustomDialog implements CallbackInterface {
...
public void showText(String text) {
textView.setText(text);
}
}
Pass an instance of your CustomDialog to the adapter (make sure to redefine adapter constructor to accept an instance of CustomDialog
public void callDialog() {
...
// I'm assumming you are passing a list of data here
WritingNovelAdapter adapter = new WritingNovelAdapter(context, dataList, this);
writing_dialog_recy.setAdapter(adapter);
...
}
Call the callback method from the adapter class when the recyclerview cell is clicked
public class WritingNovelAdapter extends RecyclerView.Adapter<WritingNovelAdapter.Holder> {
private Context context;
private ArrayList<WritingNovel_data> dataList;
private CallbackInterface callbackInterface;
public WritingNovelAdapter(Context context, ArrayList<WritingNovel_data>
dataList, CallbackInterface callbackInterface){
this.context = context;
this.dataList = dataList;
this.callbackInterface = callbackInterface;
}
...
holder.dialog_container.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
callbackInterface.showText(title);
}
});
}
Edit #1
Your comment stated that your dialog is not showing up. Unless you left some code out of your CustomDialog class, this is because all your CustomDialog class is, is a Java class. You need to extend a superclass such as AlertDialog or DialogFragment. I'll do my best to summarize how to do this, but you should take a look at the android docs -> https://developer.android.com/guide/topics/ui/dialogs
Here is an example of a DialogFragment you could try creating:
public class CustomDialog extends DialogFragment implements CallbackInterface {
private Context context;
private TextView textView;
private RecyclerView writing_dialog_recy;
public CustomDialog(Context context) {
this.context = context;
}
/* This is the method which builds and essentially shows the dialog */
#Override
public Dialog onCreateDialog(#Nullable Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
LayoutInflater inflater = getActivity().getLayoutInflater();
// Inflate your view that contains the recyclerview
View view = inflater.inflate(R.layout.custom_dialog);
// Your text view where you want to show the text after an item is clicked
textView = view.findViewById(R.id.textView8);
// Your recyclerview in your custom_dialog.xml
writing_dialog_recy = view.findViewById(R.id.writing_dialog_recy);
// Create the layout manager
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(context);
writing_dialog_recy.setLayoutManager(layoutManager);
// Create and set the adapter
WritingNovelAdapter adapter = new WritingNovelAdapter(context, dataList, this);
writing_dialog_recy.setAdapter(adapter);
builder.setView(view);
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// do whatever you want when user clicks the positive button
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
return builder.create(); // return the dialog builder
}
public void showText(String text) {
textView.setText(text);
}
}
Then in whatever activity you are creating this dialog from, you show the DialogFragment and pass it the activity's FragmentManager and a tag
CustomDialog dialog = new CustomDialog(this);
dialog.show(getSupportFragmentManager(), "CustomDialog");

How do I implement the holder.itemView.setOnClickListener from the UserAdapter in a fragment?

I apologize about the title, I wasn't sure how to phrase my question correctly.
I have a UserAdapter, a Chatlist and a Searchfragment and the user_item. The problem is, the three Click Listeners "Follow", "Go to user's profile" and "Go to chatActivity" are available on both Fragments.
I want, that the "Go to user's profile" click listener only work in the Searchfragment but not in the Chatlistfragment and also hide the "follow/following" button on the Chatlistfragment. Right now they work on both fragments.
I'll appreciate any help!

Generally in this case, just having a boolean in the constructor of the adapter will do the job.
Let's say your isFragment boolean is used for this. So follow button visibility just set to GONE if isFragment is true and when clicking on "Go to user's profile" button just do this:
if (isFragment)
return
Hope that helps you.

Display words in a recyclerview from a second activity

I am trying to display a word from a second activity to my main activity which is inform of a recycler view with a textview item.
I have created my adapter and I am assuming it works fine the only problem is once I launch my floating button to access my display word activities it does not display on the main activity, what am I doing wrong, I am new to Android.
My Adapter :
public class RoomAdapter extends RecyclerView.Adapter<RoomAdapter.RoomViewHolder> {
private List <RoomPojo> word;
public RoomAdapter(List <RoomPojo> word1){
this.word = word1;
}
#NonNull
#Override
public RoomViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View layoutInflater = LayoutInflater.from(parent.getContext()).inflate(R.layout.word_item,parent,false);
return new RoomViewHolder(layoutInflater);
}
#Override
public void onBindViewHolder(#NonNull RoomViewHolder holder, int position) {
holder.wordTextView.setText(word.get(position).getWord());
}
#Override
public int getItemCount() {
return word.size();
}
public class RoomViewHolder extends RecyclerView.ViewHolder{
private TextView wordTextView;
public RoomViewHolder(View itemView) {
super(itemView);
wordTextView = itemView.findViewById(R.id.display_word);
}
}
}
Here is my Main activity:
public class MainActivity extends AppCompatActivity {
private RoomAdapter roomAdapter;
public static final int NEW_WORD_ACTIVITY_REQUEST_CODE = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {

Here is my display word which has a button and a edit text which should take just one string.
public class DisplayWord extends AppCompatActivity {
public static final String EXTRA_KEY = "key";
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_word);
final EditText editText = findViewById(R.id.word_edit_text);
Button button = findViewById(R.id.word_button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent replyIntent = new Intent();
if(TextUtils.isEmpty(editText.getText())){
setResult(RESULT_CANCELED, replyIntent);
}else {
String word = editText.getText().toString();
replyIntent.putExtra(EXTRA_KEY,word);
}
finish();
}
});
}
}

Your code should be like this :
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent replyIntent = new Intent();
if(TextUtils.isEmpty(editText.getText())){
setResult(RESULT_CANCELED, replyIntent);
}else {
String word = editText.getText().toString();
replyIntent.putExtra(EXTRA_KEY,word);
setResult(RESULT_OK, replyIntent); //missing
}
finish();
}
});
Then After handle it in MainActivity.java
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
String requiredValue = data.getStringExtra(DisplayWord.EXTRA_KEY);
}
} catch (Exception ex) {
Toast.makeText(Activity.this, ex.toString(),
Toast.LENGTH_SHORT).show();
}
}

all fragments are loading at time of activity

I am very...very new to android development and I am trying to recreate a hybrid app I built in ionic, but do it in actual android.
I am having an issue with either layouts or fragment loading that I can't figure out.
What I want is something similar to the IG layout, where there is a bar at the bottom for navigation, clicking the button would load the new page. From my understanding the best way to accomplish that is to use a main activity, then each of the tabs at the bottom are fragments.
So I built that, but I want the top toolbar to disappear on the second tab, so in the second tab "onCreateView" method I added the toolbar.setVisibility(View.GONE); however, as soon as I load the app, even on the first tab, the toolbar at the top is gone, signifying it is loading the views for each fragment when the app loads. I would think that would severely impact performance on a large app. Am I crazy?
Here is my main layout for the main activity...
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/main_layout">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#color/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.v4.view.ViewPager
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/toolbar" />
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
android:gravity="center_horizontal"
android:layout_gravity="center_horizontal"
android:background="?attr/colorPrimary"
android:elevation="6dp"
app:tabSelectedTextColor="#FFFFFF"
app:tabTextColor="#D3D3D3"
app:tabIndicatorColor="#FF00FF"
android:minHeight="?attr/actionBarSize"
android:layout_alignParentBottom="true" />
</RelativeLayout>
Then my HomeActivity class..
public class HomeActivity extends BaseActivity implements OnFragmentTouched {
private TextView mTextMessage;
private static final String SELECTED_ITEM = "arg_selected_item";
private int mSelectedItem;
private BottomNavigationView mBottomNav;
private FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putInt(SELECTED_ITEM, mSelectedItem);
super.onSaveInstanceState(outState);
}
#Override
public void onBackPressed() {
MenuItem homeItem = mBottomNav.getMenu().getItem(0);
if (mSelectedItem != homeItem.getItemId()) {
// select home item
selectFragment(homeItem);
} else {
super.onBackPressed();
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
ViewPager pager = (ViewPager) findViewById(R.id.content);
PagerAdapter pagerAdapter = (PagerAdapter) new PagerAdapter(getSupportFragmentManager(), HomeActivity.this);
pager.setAdapter(pagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.setupWithViewPager(pager);
for(int i = 0; i < tabLayout.getTabCount(); i++) {
TabLayout.Tab tab = tabLayout.getTabAt(i);
tab.setCustomView(pagerAdapter.getTabView(i));
}
}
private void selectFragment(MenuItem item) {
Fragment frag = null;
switch(item.getItemId()) {
case R.id.navigation_home:
frag = new AllPostsFragment();
break;
case R.id.navigation_dashboard:
frag = ProfileFragment.newInstance(user.getUid());
break;
case R.id.navigation_notifications:
frag = new ChatListFragment();
break;
}
mSelectedItem = item.getItemId();
}
#VisibleForTesting
public ProgressDialog mProgressDialog;
public void showProgressDialog() {
if (mProgressDialog == null) {
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setMessage(getString(R.string.loading));
mProgressDialog.setIndeterminate(true);
}
mProgressDialog.show();
}
public void hideProgressDialog() {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.dismiss();
}
}
#Override
public void onStop() {
super.onStop();
hideProgressDialog();
}
#Override
public void onFragmentTouched(Fragment fragment, float x, float y) {
Log.d("FRAGMENT_TOUCHED", "The ChatListFragment touch happened");
if(fragment instanceof ChatFragment) {
final ChatFragment theFragment = (ChatFragment) fragment;
Animator unreveal = theFragment.prepareUnrevealAnimator(x, y);
unreveal.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
}
#Override
public void onAnimationEnd(Animator animation) {
getSupportFragmentManager().beginTransaction().remove(theFragment).commit();
getSupportFragmentManager().executePendingTransactions();
}
#Override
public void onAnimationCancel(Animator animation) {}
#Override
public void onAnimationRepeat(Animator animation) {}
});
unreveal.start();
}
}
public String getUid() {
return FirebaseAuth.getInstance().getCurrentUser().getUid();
}
private class PagerAdapter extends FragmentPagerAdapter {
Context context;
String tabTitles[] = new String[] {"Home", "Profile", "Chat"};
public PagerAdapter(FragmentManager fm, Context context) {
super(fm);
this.context = context;
}
#Override
public Fragment getItem(int pos) {
switch(pos) {
case 0: return new AllPostsFragment();
case 1: return ProfileFragment.newInstance(user.getUid());
case 2: return new ChatListFragment();
default:
return new AllPostsFragment();
}
}
#Override
public int getCount() {
return tabTitles.length;
}
#Override
public CharSequence getPageTitle(int position) {
return tabTitles[position];
}
public View getTabView(int position) {
View tab = LayoutInflater.from(HomeActivity.this).inflate(R.layout.custom_tab, null);
TextView tv = (TextView) tab.findViewById(R.id.custom_text);
tv.setText(tabTitles[position]);
return tab;
}
}
}
So, in the "ProfileFragment" in the onCreateView method I have...
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_profile, container, false);
recyclerView = (RecyclerView) rootView.findViewById(R.id.userPostsRecycler);
RecyclerView.LayoutManager layoutManager = new GridLayoutManager(getContext(), 2);
recyclerView.setLayoutManager(layoutManager);
Toolbar toolbar = getActivity().findViewById(R.id.toolbar);
toolbar.setVisibility(View.GONE);
followingCountText = rootView.findViewById(R.id.following_count);
followersCountText = rootView.findViewById(R.id.followers_count);
titleLayout = rootView.findViewById(R.id.toolbar_layout);
titleLayout.setTitle(user.getDisplayName());
fab1Container = rootView.findViewById(R.id.fab_1);
fab2Container = rootView.findViewById(R.id.fab_2);
ImageView profilePhoto = (ImageView) rootView.findViewById(R.id.profile_photo);
Glide.with(this).load(user.getPhotoUrl()).into(profilePhoto);
fabContainer = (LinearLayout) rootView.findViewById(R.id.fabContainerLayout);
fab = (FloatingActionButton) rootView.findViewById(R.id.profile_fab);
instigatingFab = fab;
fabBaseX = fab.getX();
fabBaseY = fab.getY();
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
showBlurredDialog();
}
});
progressDialog = new ProgressDialog(getContext());
uploads = new ArrayList<>();
progressDialog.setMessage("Please wait...");
progressDialog.show();
DatabaseReference followersDB = FirebaseDatabase
.getInstance()
.getReference("followers")
.child(user.getUid())
.child("count");
followersDB.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
int followersCount = dataSnapshot.getValue(Integer.class);
followersCountText.setText(Integer.toString(followersCount));
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
DatabaseReference followingReference = FirebaseDatabase.getInstance().getReference("following").child(user.getUid()).child("users");
followingReference.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
DatabaseReference followingDB = FirebaseDatabase.getInstance().getReference("following").child(user.getUid()).child("count");
followingDB.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
int followingCount = dataSnapshot.getValue(Integer.class);
followingCountText.setText(Integer.toString(followingCount));
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
mDatabase = FirebaseDatabase.getInstance().getReference("/userPosts").child(user.getUid()).child("posts");
mDatabase.limitToFirst(25).addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
progressDialog.dismiss();
for(DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
String postID = postSnapshot.getKey();
uploads.add(postID);
}
uploads.add("-KtvzkOL_75wiKA4CMsr");
adapter = new ProfileUserPostsViewHolder(getContext(), uploads);
recyclerView.setAdapter(adapter);
}
#Override
public void onCancelled(DatabaseError databaseError) {
progressDialog.dismiss();
}
});
return rootView;
}
As you can see I am setting the visibility for the toolbar from the HomeActivity to View.GONE, however, the toolbar is gone from all fragments now. I just want a bottom navigation setup with a top toolbar that can be hidden when certain fragments load, but is visible in other fragments. Is that even possible? Thank you.

You can control the numbers of fragments loading in view pager by simply using this method:
viewPager.setOffscreenPageLimit(1); // where n is the number of offscreen pages you want to load.
you can increase or decrease the number of fragments loading according to your requirements but atleast 1.
hope this will help you.
