Can hide ProgressBar but cannot show it

I'm using the default ProgressBar widget, for indeterminate progress, in a Linear Layout with Style: #android:style/Widget.DeviceDefault.Light.ProgressBar.Small
If I start the activity with the ProgressBar VISIBLE and never make it INVISIBLE or GONE it shows ok. But if I put progressBar.setVisibility(progressBar.GONE); or progressBar.setVisibility(progressBar.INVISIBLE); anywhere in my code, the space for the ProgressBar is on the UI, but I cant see it.
I thought it might be a leaky parallel thread and removed all multi-threading from my app, but it still won't appear if INVISIBLE or GONE is anywhere in my code.
It works fine on other Activities.

In the Activity onCreate I call populateMemberTeams(); I added a CountDownTimer to check if the progressBar is on the screen and it is...Before the 2 seconds, there is a empty space, but I can't see the ProgressBar
When the timer expires the UI adjusts when the ProgressBar changes to GONE.
private void populateMemberTeams() {
ListView myTeamsListView = findViewById(R.id.myTeamsListView);
ProgressBar progressBar = findViewById(R.id.myTeamsProgressBar);
progressBar.setVisibility(progressBar.VISIBLE);
mAuth = FirebaseAuth.getInstance();
String userId = mAuth.getCurrentUser().getUid();
callTeamManagement.populateMemberTeams(TAG, passedActivity, context, userId);
new CountDownTimer(2000, 1000) {
public void onFinish() {
progressBar.setVisibility(progressBar.GONE);
}
public void onTick(long millisUntilFinished) {
// millisUntilFinished The amount of time until finished.
}
}.start();
}
I have tried:
Changing the ProgressBar style in case it was a colour issue;
INVISIBLE instead of GONE;
Putting the ProgressBar inside its own LinearLayout
progressBar.setVisibility(progressBar.VISIBLE);
progressBar.setVisibility(View.VISIBLE);
progressBar.setVisibility(ProgressBar.VISIBLE);

You should use runOnUiThread.
Helper method for running part of a method on the UI thread.
runOnUiThread(new Runnable() {
#Override
public void run() {
progressBar.setVisibility(View.VISIBLE);
//progressBar.setVisibility(View.INVISIBLE);
//progressBar.setVisibility(View.GONE);
}
});

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 :

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

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();
}

Check recyclerview scroll state inside nestedscrollview

I'm using a recyclerview inside NestedScrollView and I want to pin my search bar to action bar after scrolling and recyclerview items must show under searchbar, I need to make lazy load for my recyclerview items (load next items from server after scrolling to end) for this I need to check recyclerview scroll change state and I can't do this perfectly when I use recyclerview inside nestedscrollview. I tried using nestedscrollview scroll state change listener and it doesn't give me what I want and doesn't work right.
Nested scroll view is not working if it's placed inside recyclerview. I have lazy load recyclerview but same layout contain other layouts like slider, menus then recyclerview. I want to scroll full layout and when recyclerview ends onscroll then onload execute to get more item from internet and load in recylerview.
Here you see my codes:

My code to check scroll state and it didn't work
nested_content.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
#Override
public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY)
{
if (scrollY < oldScrollY)
{ // up
((MainActivity)getActivity()).animateNavigation(false);
}
if (scrollY > oldScrollY)
{ // down
((MainActivity)getActivity()).animateNavigation(true);
}
if (scrollY == ( v.getChildAt(0).getMeasuredHeight() - v.getMeasuredHeight() ))
{
if (!is_loading)
{
if (current_page < all_pages)
{
//not work right scroll state
}
}
}
}
});

i got the answer, if any one have my problem see below...
for detect nestedscrollview is at end correctly use this code:
nested_content.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
#Override
public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY)
{
if (scrollY < oldScrollY)
{ // up
((MainActivity)getActivity()).animateNavigation(false);
}
if (scrollY > oldScrollY)
{ // down
((MainActivity)getActivity()).animateNavigation(true);
}
View view = (View) nested_content.getChildAt(nested_content.getChildCount() - 1);
int diff = (view.getBottom() - (nested_content.getHeight() + nested_content
.getScrollY()));
if (diff == 0)
{
if (merchantList.size()>0)
{
if (!is_loading)
{
if(current_page<=all_pages)
{
// nestedscrollview at end
getMerchants(current_page);
}
}
}
}
}
});

Listview not scrolling untill the last Item

Hello there I am have having problem scrolling untill the last item scrolling stops in the middle, here is my layout code.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="fragment.Equivalent">
<ListView
android:id="#+id/listView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="visible"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:focusable="false"/>
<TextView
android:id="#+id/txt404"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Message that will be shown if the listview is empty"
android:textSize="21dp"
android:textStyle="bold"
android:visibility="invisible" />
</RelativeLayout>

Try with a scroll view:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="fragment.Equivalent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:scrollbarStyle="insideOverlay"
style="#android:style/Widget.Holo.ScrollView">
<TableLayout
android:id="#+id/table_layout_id"
android:layout_width="match_parent"
android:layout_height="match_parent">
</TableLayout>
</ScrollView>
</RelativeLayout>
in java file, do this:
TableLayout ll = (TableLayout) findViewById(R.id.table_layout_id);
TableRow row = new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(lp);

 
 butt = new Button(this);
 //You can add button too, FYI
butt.setText("TEST");
 
 
TextView tv = (TextView) findViewById(R.id.txt404);

tv.setText("Text view");
tv2 = new TextView(this);
 //your job: add list view here
tv2.setText("Text View 2");
 
 
row.addView(butt);

 row.addView(tv1);
row.addView(tv2);
 
ll.addView(row, i); // where i is the row number, increment on addition

Solution was changing the layout to a constraint layout and changing the size of the listview

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

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.
