TextViews aren't appearing when created programmatically

Programmatically created TextViews aren't appearing when I run my app. I am trying to download messages and the person that sent them from Firebase and display them in separate TextViews with the sender TextView on top.
Sorry for the lack of information, but I don't know what I've done wrong.
db.collection("messagesIT")
.orderBy("Timesent", Query.Direction.DESCENDING)
.get()
.addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
#Override
public void onComplete(#NonNull Task<QuerySnapshot>task) {
if (task.isSuccessful()) {
ArrayList<MessageObj> messages = new ArrayList<>();
for (QueryDocumentSnapshot document : task.getResult())
String message = document.getString("Message");
String sender = document.getString("Sender");
Timestamp timesent = document.getTimestamp("Timesent");
MessageObj mess = new MessageObj(message, sender, timesent);
messages.add(mess);
Log.d(TAG, "m: " + mess.getMessage());
Log.d(TAG, "s: " + mess.getSender());
Log.d(TAG, "t:" + mess.getTimesent());
showToast("b");
}
TableLayout tl = findViewById(R.id.TableLayoutSubjectGroupPage);
//reading and displaying messages
for (int i = 0; i < messages.size(); i++) {
TableRow trMessage = new TableRow(SubjectGroupPage.this);
TableRow trSender = new TableRow(SubjectGroupPage.this);
TextView txtSender = new TextView(SubjectGroupPage.this);
TextView txtMessage = new TextView(SubjectGroupPage.this);
Log.d(TAG, "uv8iygv iyrtgcvfi8ytgvcrcccccccccccccccccccccccccccc");
LinearLayout.LayoutParams Weight = new LinearLayout.LayoutParams(0, TableRow.LayoutParams.WRAP_CONTENT, 1);
txtSender.setText(messages.get(i).getSender());
txtSender.setLayoutParams(Weight);
txtMessage.setText(messages.get(i).getMessage());
txtMessage.setLayoutParams(Weight);
txtMessage.setTextSize(20);
txtMessage.setTextColor(Color.parseColor("#000000"));
if (messages.get(i).getSender().equals(currentUser.getUid())) {
txtMessage.setTextAlignment(View.TEXT_ALIGNMENT_TEXT_END);
txtSender.setTextAlignment(View.TEXT_ALIGNMENT_TEXT_END);
} else {
txtMessage.setTextAlignment(View.TEXT_ALIGNMENT_TEXT_START);
txtSender.setTextAlignment(View.TEXT_ALIGNMENT_TEXT_START);
}
//creating message display
trSender.addView(txtSender);
trMessage.addView(txtMessage);
tl.addView(trSender);
tl.addView(trMessage);

I think you forget to add layout params for table row.
BTW you should use recycler view with two view holders one for sender and 2nd for the receiver.
checkout if you want to improve your code
How to create RecyclerView with multiple view type?
or
https://medium.com/#droidbyme/android-recyclerview-with-multiple-view-type-multiple-view-holder-af798458763b

You explictly set the width of your TextViews to zero, using:
public LinearLayout.LayoutParams (int width, int height, float weight)
...where (see LinearLayout.LayoutParams):
int: the width, either ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT or a fixed size in pixels
MATCH_PARENT has a value of -1 and WRAP_CONTENT a value of -2. So this code sets a fixed width of 0:
LinearLayout.LayoutParams Weight = new LinearLayout.LayoutParams(0, TableRow.LayoutParams.WRAP_CONTENT, 1)
Instead you should use:
TableLayout.LayoutParams tableParams_forRow = new TableLayout.LayoutParams(TableLayout.LayoutParams.WRAP_CONTENT, TableLayout.LayoutParams.WRAP_CONTENT);
and
TableRow.LayoutParams rowParams_forTextView = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT);
See this answer, for an example

};
}
So my problem is when I touch/click textview first time "toast" fired up datepicker is not showing up, but after that every time when I touch/click I can see datepicker? Why datepicker is not showing up when I press textview first time? How to make it to works?
vikas kumar thanks that help

The reason is for the first time when you click it sets up click listener as you have set in setDate(View view); after that, it listens for subsequent calls. so you need to change the method a bit.
public void setDate(View view){
selectedTextView = (TextView) view;
showDialog(0);
}
or you can just do this at the site of onClick also for date pickers.
periodFromText.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view){
Toast.makeText(getApplicationContext(), "WORKS!", Toast.LENGTH_SHORT).show();
selectedTextView = (TextView) view;
showDialog(0);
}
});
this doesn't require you to set two onClickListeners for the same TextView.

Modify your setDate() method to below
public void setDate(View view){
selectedTextView = (TextView) view;
showDialog(0);
}

Moving imageview in XML causes crash

Returning values from a custom dialog view

I'm trying to make a custom dialog for my android application. I get null pointer exceptions when I attempt to access the fields from the 'ok' button method. It seems like my fields fade from existence as soon as the onclick listener fires. Is there a better way to do this?

addView.findViewById(R.id.inHP) instead of findViewById(R.id.inHP)

The problem is that you are calling addView.findViewById inside your onClick event, the onclick doesn't really happen until somebody clicks on it, I'll suggest that you make addView class member variable so that it can persist in memory. That'll solve your problem.
