Not displaying TextView text correctly via ArrayAdapter?

Question

Java

Made it so that each incoming message is written to its own TextView.
This method is called on the thread.

public void inputMessage(){
            try {
                InputStream inputStream = socket.getInputStream();
                DataInputStream dataInputStream = new DataInputStream(inputStream);
                String stringInputMessage;
                while (true){
                    if ((stringInputMessage = dataInputStream.readUTF()) != null){
                        final String finalStringInputMessage = stringInputMessage;
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                TextView textViewMessage = createTextView();
                                textViewMessage.setText(finalStringInputMessage);
                                listMessage.add(textViewMessage);
                                listViewMessage.setAdapter(arrayAdapterMessage);
                            }
                        });
                    }
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

This one is separate from the stream.

private TextView createTextView() {
        textViewMessage = new TextView(this);
        return textViewMessage;
    }

In the end, this is the picture.

Elements are added, but there is no text on them.

The problem is with the adapter.
No need to create a new TextView for new messages, just add the message to the list of all messages and pass that list to the adapter to update the ListView (in this case, get a reusable TextView out of the box):

List<String> messages = new ArrasyList<>();

//when new message arrives
messages.add(msg);

//update adapter
arrayAdapterMessage.setMessages(messages) ;
arrayAdapterMessage.notifyDatasetChanged();

The adapter will be responsible for creating and reusing the TextView.
