I am making chat app but when I send message recycler view does not show first 2 messages because it is up I want something like whatsapp if I open keyboard recycler view is shown from start I tried following but it sticks chats to end even after I close keyboard:
LinearLayoutManager layoutManager = new LinearLayoutManager(getApplicationContext());
layoutManager.setStackFromEnd(true);
recyclerView.setLayoutManager(layoutManager);
. following is my code:
public class UserChat extends AppCompatActivity {
private RecyclerView recyclerView;
private Button btnSend;
private EditText messageBox;
private TextView name_txt;
final ArrayList<ChatModel> chatModels = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_chat);
recyclerView = findViewById(R.id.chat_list);
messageBox = findViewById(R.id.et_chat_box);
btnSend = findViewById(R.id.btn_chat_send);
name_txt = findViewById(R.id.name_txt);
String username = "username not set";
Bundle extras = getIntent().getExtras();
if(extras!=null){
username = extras.getString("username");
}
name_txt.setText(username);
btnSend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int i = 1;
i ;
ChatModel chatModel = new ChatModel();
chatModel.setId(i);
chatModel.setMe(true);
chatModel.setMessage(messageBox.getText().toString().trim());
chatModels.add(chatModel);
ChatAdapter chatAdapter = new ChatAdapter(chatModels, getApplicationContext());
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
recyclerView.setAdapter(chatAdapter);
messageBox.setText("");
}
});
}
}
following is my XML :

CodePudding user response:
There was a problem in height of the recycler view. I saw it here: https://github.com/stfalcon-studio/ChatKit/issues/103. @andriizhumela said that you need to put match parent in width and height of recycler view . so now it is solved
