Android List View shows items, but text is empty

I am experiencing a very weird issue where I am unable to view any text/data, but it clearly shows the number of items in the list.
I have confirmed that dataList has data, and I am able to get the exact same string that I set after debugging.
Parent Fragment:
ListView InboxListView = (ListView) view.findViewById(R.id.listViewInbox);
InboxAdapter adapter = new InboxAdapter(mActivity, R.layout.activity_inbox_item, dataList, NotificationInbox.this);

EDIT: Screenshot added
EDIT2: Clarified parent fragment calling the adapter.
EDIT3: I did a temporary fix. Apparently the RelativeLayout and the Linear Layout in the AdapterXML were the cause of my misery. I'm not exactly sure why, though. I think it's the RelativeLayout and the LinearLayout somehow not displaying the text. Removing those two tags will display the texts in a linear fashion.

Try this

how to add bottom layout in Modal BottomSheet Dialog?

I want to achieve the design like this using BottomSheetDialogFragment. But the problem is the bottom layout get scrolled when i drag. I want the bottom layout always in bottom until the BottomSheetDialogFragment gets dismissed.
Please find the screenshot
Here is my code
bottomsheet_layout.xml
<?xml version="1.0" encoding="utf-8"?>

use this layout instead of your layout ....
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/activity_main"
android:layout_width="match_parent"

android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="10"
android:orientation="vertical">
<!--The main content goes over here-->
</LinearLayout>
</ScrollView>
<!--The footer view-->
<LinearLayout
android:id="#+id/footer_purchase_layout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="horizontal"
android:weightSum="1">
<TextView
android:id="#+id/txt_cancel_purchase"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.5"
android:gravity="left|center_vertical"
android:text="CLOSE"
android:textSize="14sp" />
<TextView
android:id="#+id/txt_item_purchase_action"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.5"
android:gravity="right|center_vertical"
android:text="ADD STICKERS"
android:textSize="14sp" />
</LinearLayout>
</LinearLayout>
</FrameLayout>
Note:- Weight divide your Layout into different View which is constant in your layout ......

use this layout:

Title in the BottomSheet

I have a BottomSheet with a RecyclerView, and I want to add a title there as in the picture below ("Add new record"), I was trying to add TextView before the RecyclerView in the bottom_sheet LinearLayout, but this text doesn't appear on the screen, also I was trying to add an item in the RecyclerView (but I have a feeling that it's not a right approach), so my question is how to add the title to the BottomSheet?
This is the method where I'm adding items to the RecyclerView, which is in the BottomSheet:
private void showBottomSheetDialog() {
if (behavior.getState() == BottomSheetBehavior.STATE_EXPANDED) {
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
mBottomSheetDialog = new BottomSheetDialog(this);
View view = getLayoutInflater().inflate(R.layout.sheet, null);
RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(new ItemAdapter(createItems(), new ItemAdapter.ItemListener() {
#Override
public void onItemClick(Item item) {
if (mBottomSheetDialog != null) {
mBottomSheetDialog.dismiss();
}
}
}));
mBottomSheetDialog.setContentView(view);
mBottomSheetDialog.show();
mBottomSheetDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
mBottomSheetDialog = null;
}
});
}
#Override
protected void onDestroy() {
super.onDestroy();
mAdapterItem.setListener(null);
}
public List<Item> createItems() {
ArrayList<Item> items = new ArrayList<>();
items.add(new Item(R.drawable.camera, "from new shoots"));
items.add(new Item(R.drawable.folder_multiple_image, "from ready images"));
return items;
}

FloatingActionButton doesn't start invisible

I want to do a FAB which is opening 2 other FABs to left after clicking. But it doesn't start invisibled. I used all way in those codelines but It doesn't work. (ScaleX-Y = 0, android:invisibility, setInvisibility etc..)
DersActivity.java
private Boolean isFabOpen = false;
private FloatingActionButton fab_ders, fab_ders_ara, fab_ders_ekle;
private Animation fab_open, fab_close, rotate_forward, rotate_backward;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
...
fab_ders = (FloatingActionButton) findViewById(R.id.fab_ders);
fab_ders_ara = (FloatingActionButton) findViewById(R.id.fab_ders_ara);
fab_ders_ekle = (FloatingActionButton) findViewById(R.id.fab_ders_ekle);
fab_open = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fab_open_ders);
fab_close = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fab_close_ders);
rotate_forward = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.rotate_forward);
rotate_backward = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.rotate_backward);
fab_ders.setOnClickListener(this);
fab_ders_ara.setOnClickListener(this);
fab_ders_ekle.setOnClickListener(this);
...
...
}
#Override
public void onClick(View v) {
int id = v.getId();
switch (id) {
case R.id.fab_ders:
animateFAB();
break;
case R.id.fab_ders_ara:
Log.d("Test", "Fab 1");
break;
case R.id.fab_ders_ekle:
Log.d("Test", "Fab 2");
break;
}
}
public void animateFAB() {
if (isFabOpen) {
fab_ders.startAnimation(rotate_backward);
fab_ders_ara.startAnimation(fab_close);
fab_ders_ekle.startAnimation(fab_close);
fab_ders_ara.setClickable(false);
fab_ders_ekle.setClickable(false);
isFabOpen = false;
Log.d("Test", "close");
} else {
fab_ders.startAnimation(rotate_forward);
fab_ders_ara.startAnimation(fab_open);
fab_ders_ekle.startAnimation(fab_open);
fab_ders_ara.setClickable(true);
fab_ders_ekle.setClickable(true);
isFabOpen = true;
Log.d("Test", "open");
}
}
I used Animation in this file but It doesn't matter to problem.

Android Eclipse Start Fragment from TabLayout Tab

I have implemented a TabLayout which has a few tabs & one of the tabs has a table & when a user clicks on a row in the table I need it to get rid of the tab layout, except for the toolbar & open up a new Fragment.
I've tried a few different ways but nothing seems to work, if anyone has any ideas, it'll will be much appreciated!
Thank you!
Cheers!

I think you need to give the fragment somewhere to replace. Here is the XML from my app, and when I swap fragments, they post to flcontent.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk
xmlns:app="http://schemas.android.com/apk/res
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- The ActionBar -->
<include
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
<!-- The main content view -->
<FrameLayout
android:id="#+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent"
</LinearLayout>
<!-- The navigation drawer -->
<android.support.design.widget.NavigationView
android:id="#+id/nvView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/white"
app:menu="#menu/drawer_view"
app:headerLayout="#layout/nav_header"/>
and the class code
// Insert the fragment by replacing any existing fragment
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.flContent, fragment);
ft.addToBackStack(null);
ft.commit();

Alright so I think that I figured out a really cheap & a cheeky way to do this & probably not very healthy for the app but it works perfect!
Thank you very much for the help Brian! Appreciate it! Maybe you can do this for the backstack problem of your app as well, don't know if it will work or the right thing that you need to do though.
Cheers!
Added a FrameLayout to my main_activity.xml
<RelativeLayout
android:id="#+id/main_layout"

android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"

android:layout_below="#id/tab_layout"/>
<FrameLayout
android:id="#+id/flContent"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
</RelativeLayout>
Changed my newfragment.xml to this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fullStoryLinearLayout"
android:layout_width="match_parent"

<RelativeLayout
android:id="#+id/fullStoryRelativeLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1.04" >
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="17dp"
android:layout_marginTop="80dp"/>
<TextView
android:id="#+id/fullStorytitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/imageView1"
android:layout_centerHorizontal="true"
android:layout_marginTop="80dp"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/fullStory"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/image"
android:layout_marginTop="50dp"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
</LinearLayout>
& added this to the onClick event of the table row
row.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
getActivity().findViewById(R.id.tab_layout).setVisibility(View.GONE);
getActivity().findViewById(R.id.pager).setVisibility(View.GONE);
((AppCompatActivity)getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((AppCompatActivity)getActivity()).getSupportActionBar().setTitle("New Fragment");
Fragment fragment = null;
Class fragmentClass = NewFragment.class;
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.flContent, fragment);
fragmentTransaction.commit();
}
});
& to go back to the main TabLayout from the NewFragment, I added this at MainActivity.java
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case android.R.id.home:
onBackPressed();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch(keyCode){
case KeyEvent.KEYCODE_BACK:
if (getSupportActionBar().getTitle() != "Main Activity"){
onBackPressed();
}
else {
System.exit(0);
}
return true;
}
return super.onKeyDown(keyCode, event);
}
public void onBackPressed(){
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setTitle("Main Activity");
findViewById(R.id.fullStoryLinearLayout).setVisibility(View.GONE);
findViewById(R.id.tab_layout).setVisibility(View.VISIBLE);
findViewById(R.id.pager).setVisibility(View.VISIBLE);
}
