recycler view hides message upward when keyboard is open / how to keep recycler View from scrolling when keyboard is on

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("");
}
});
}
}

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

Android: Button doesn't work, but code doesn't show any error

I'm trying to create a form to capture data, I need to access the camera to take pictures. My problem is when I try to call the camera with imagenButton, it's not working but the code doesn't show any error.
Here's my fragment to declare form:
public class EspecimenesInsertarFragment extends Fragment implements
Response.Listener<JSONObject>, Response.ErrorListener {
private EspecimenesViewModel especimenesViewModel;
RequestQueue rq;
JsonRequest jrq;
final int COD_SELECCIONA=10;
final int COD_FOTO=20;
private static final int REQUEST_IMAGE_CAMERA=101;
private static final int REQUEST_PERMISSION_CAMERA=101;
Button btnGuardar, btnCancelar;
ImageButton btnCamara, btnGaleria;
ImageView imageView;
public static final int MY_DEFAULT_TIMEOUT = 50000;
public EspecimenesInsertarFragment() {
// Required empty public constructor
}
public static EspecimenesInsertarFragment newInstance() { return new EspecimenesInsertarFragment();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view;
view = inflater.inflate(R.layout.fragment_colecciones_insertar, container, false);
imageView = (ImageView)view.findViewById(R.id.imageView);
btnCamara=(ImageButton) view.findViewById(R.id.tomarFoto);
btnGuardar = (Button) view.findViewById(R.id.buttonIngresarEspecimenes);
rq = Volley.newRequestQueue(getContext());
/* if(validaPermisos()){
btnCamara.setEnabled(true);
}else{
btnCamara.setEnabled(false);
} */
if (ContextCompat.checkSelfPermission(getContext(), WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED &&
ActivityCompat.checkSelfPermission(getContext(), Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(getActivity(), new String[]{WRITE_EXTERNAL_STORAGE,
Manifest.permission.CAMERA}, 1000);
}
btnGuardar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
registrar_especimen("http://localhost/BIO-UES-APP/EspecimenesController.php");
}
});
static final int REQUEST_TAKE_PHOTO=1;
public void tomarFoto(View view){
Intent takePictureInent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Log.d("entra","");
if(takePictureInent.resolveActivity(getActivity().getPackageManager())!= null){
File photoFile=null;
try {
photoFile=createImageFile();
}catch (IOException ex){
}
if(photoFile!=null){
Uri photoUri=FileProvider.getUriForFile(getActivity(),"com.example.luvin.drawercero",photoFile);
takePictureInent.putExtra(MediaStore.EXTRA_OUTPUT,photoUri);
getActivity().startActivityForResult(takePictureInent,REQUEST_TAKE_PHOTO);

Logcat message when button is pressed:

To complete my question, I have the permissions in the manifest. I already tried to call the camera in another way, tried creating the method in the MainActivity to create the OnClick event in the XML Layout, but nothing works.
If anyone knows how to solve this issue please help.
Thanks.

You forgot to add the on click listener to your photo button. This should solve your problem:
btnCamara = view.findViewById(R.id.tomarFoto);
btnCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tomarFoto(v);
}
});

Using Custom DialogFragment as dynamic Dialog Box android-java

I created a custom dialog fragment to be used as a YesNo Dialog Box for my project as shown below
I want to use it dynamically in where I can use it not only for one xml file.
Does anybody know how can I set the button click listener in the appcompact class from the dialogfragment on call?
I just want to set the buttonclick event of the dialogfragment in another xml file.
I tried using interface but it gives me a null pointer exception so I tried the code below.
the YesNoDialogFragment Class
public class DialogYesNo extends DialogFragment {
LayoutInflater inflater;
View v;
#NonNull
#Override
public Dialog onCreateDialog(#Nullable Bundle savedInstanceState) {
inflater = getActivity().getLayoutInflater();
v = inflater.inflate(R.layout.dialog_yesno,null);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setView(v);
return builder.create();
}
}
the XML file of the DialogFragment
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="wrap_content"

android:layout_marginRight="10dp"
android:layout_marginTop="10dp"
android:background="#drawable/dialog_background"
android:layout_gravity="center">

</LinearLayout>
this is the code in the MainActivity
btnYes = dialogYesNo.getActivity().findViewById(R.id.dialog_Yes);
btnNo = dialogYesNo.getActivity().findViewById(R.id.dialog_No);
btnYes.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this,TutwithNavigation.class);
startActivity(intent);
}
});
btnNo.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// code here
}
});

try findViewById in your DialogYesNo, and add setListener for it
like this:
private OnClickListener onYesClick;
private OnClickListener onNoClick;
public Dialog onCreateDialog(#Nullable Bundle savedInstanceState) {
inflater = getActivity().getLayoutInflater();
v = inflater.inflate(R.layout.dialog_yesno,null);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setView(v);
View btnYes = v.findViewById(R.id.dialog_Yes);
View btnNo = v.findViewById(R.id.dialog_No);
btnYes.setOnClickListener(onYesClick);
btnNo.setOnClickListener(onNoClick);
return builder.create();
}
}
public void setOnYesClick(OnClickListener listener){
onYesClick = listener
}
public void setOnNoClick(OnClickListener listener){
onNoClick = listener
}
use setOnYesClick and setOnNoClick instead

Listview adapter not displaying list columns after closing of Dialog

Setup
In my app I have a section that creates rows of data to be saved in a database. Each row is built from a textbox, number box then "set" into a listview for display. Later on the user can open a "plan" created before and review the data.
I created a listview, a custom layout for the display line and figured out how to add/display each new row. However, when I perform the open, I create a dialog to display the list for plans, user selects on and the rows should display. They do not. I trace through the code and I see the arraylist for the adapter being populated and I call the notifydatasetchanged, but the main listview remains empty.
I am not using a customer adapter class, but just the Simple adapter.
This is the beginning of the Activity. I am still learning android coding so I tend to use generic names as I learn.
public class TrackItEqMainActivity extends AppCompatActivity {
/**
* ATTENTION: This was auto-generated to implement the App Indexing API.
* See https://g.co/AppIndexing/AndroidStudio for more information.
*/
private GoogleApiClient client;
public int rowCount = 1;
private static final String eTAG = "Exception";
final Context context = this;
// global variables needed for processing the add gaits display
**private ListView lstGaits;
private ListAdapter adapter;
private ArrayList<HashMap<String, String>> mylist;**
// *****
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i(eTAG, "onCreate Build");
setTitle(R.string.activityManagePlans);
setContentView(R.layout.activity_track_it_eq_build);
Toolbar mySecondaryToolbar = (Toolbar) findViewById(R.id.my_secondaryToolbar);
setSupportActionBar(mySecondaryToolbar);
setActivityBuildListeners();
// set the objects needed to handle the dynamic gaits list
ListView lstGaits = (ListView) findViewById(R.id.lstMyGaits);
mylist = new ArrayList<HashMap<String, String>>();
try {
adapter = new SimpleAdapter(this, mylist, R.layout.gaits_detail,
new String[] { "keyGait", "keyTime" }, new int[] {
R.id.txtdisplayGait, R.id.txtdisplayTime });
lstGaits.setAdapter(adapter);
} catch (Exception e) {
Log.i(eTAG, e.getMessage());
}
// ATTENTION: This was auto-generated to implement the App Indexing API.
// See https://g.co/AppIndexing/AndroidStudio for more information.
client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
}
SO when a user taps a new button a set of controls appear allowing to select a gait and enter a time. They then tap on the set button and in the set onClick, I add the data to the internal array and display the custom layout on the screen.
private Button.OnClickListener onClick_btnSet = new OnClickListener() {
#Override
public void onClick(View v) {
Spinner spinner = (Spinner) findViewById(R.id.spinner_gaits);
TextView textGait = (TextView) spinner.getSelectedView();
String gtResult = textGait.getText().toString();
TextView txtTime = (TextView) findViewById(R.id.txtSelected);
String tmeResult = txtTime.getText().toString();
buildDisplayLine(true,gtResult,tmeResult);
txtTime.setText("");
spinner.requestFocus();
}
};
The function that builds the line and adds to the array is this:
private void buildDisplayLine(boolean isNew, String gait, String time) {
HashMap<String, String> map2 = new HashMap<String, String>();
map2.put("keyGait",gait); // put the col data in
map2.put("keyTime", time); // put the col data in
mylist.add(map2);
if (isNew) {
((BaseAdapter) (adapter)).notifyDataSetChanged();
}
}
All that works although a strange side effect is that the list will not display if the number keypad is visible. When I clear it off the list appears.
Ifa use wants to look at or change a plan they tap the open button. IT display a dialog box that shows a list of plans. Tap on a plan and all the elements should display:
private final ThreadLocal<OnClickListener> onClick_btnOpen = new ThreadLocal<OnClickListener>() {
#Override
protected OnClickListener initialValue() {
return new OnClickListener() {
#Override
public void onClick(View v) {
final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.activity_track_it_eq_open_plan);
dialog.setTitle("Open Exercise Plan...");
Button diaCancelButton = (Button) dialog.findViewById(R.id.btnCancelOpen);
diaCancelButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
// get a list of files from the local app plans
final eqDatabaseService eqDB = new eqDatabaseService(context, 2);
ArrayList<HashMap<String,String>> allPlans = eqDB.getPlanList();
if (allPlans.isEmpty()) {
Toast toast = new Toast(context);
toast.setGravity(Gravity.TOP, 0, 0);
Toast.makeText(context, "No Files to open, Please create one!", Toast.LENGTH_LONG).show();
return;
}
ListView lvPlan = (ListView) dialog.findViewById(R.id.lvPlans);
try {
adapter = new SimpleAdapter(context, allPlans, R.layout.plans_columns,
new String[] { "keyName", "keyENum" }, new int[] {
R.id.txtPlanName, R.id.txtNumElements });
lvPlan.setAdapter(adapter);
} catch (Exception e) {
}
//********************************************************
lvPlan.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
TextView txtplan = (TextView) v.findViewById(R.id.txtPlanName);
String planName = txtplan.getText().toString();
List<eqSessions_dt> myPlan = eqDB.getCurrentPlan(planName);
clearGrid();
for (eqSessions_dt row : myPlan) {
buildDisplayLine(false, row.get_gait(),Integer.toString(row.get_time()));
}
((BaseAdapter)(adapter)).notifyDataSetChanged();
dialog.dismiss();
}
});
dialog.show();
}
};
}
};
I have played around with this, did look at other similar questions and answers, but didn't see anything that would explain why the notify would not work. I avoided doing a custom adapter, trying to keep this simple at first. What am I missing that stops the list from displaying. I see the arraylist being filled and all related objects are global to the activity. I'll keep playing around, but I hope otehr eyes see what I miss.

Get values from Dynamic list

Good day everyone,
I'm learning Android development and I try to build some dynamic lists for my application. And I'm stuck... like for 4 hours already.
I have two layouts:
1. main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/action_buttons"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:gravity="center"
>
<Button
android:id="#+id/button_count"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_calculate" />
<Button
android:id="#+id/button_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/button_count"
android:text="#string/button_add" />
</LinearLayout>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/action_buttons"
>
<LinearLayout
android:id="#+id/action_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</RelativeLayout>
action_list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/action_list_item_root"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/action_list_item_edittext_drinkName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/action_list_item_button_remove"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/action_list_item_title"
android:padding="10dp" />
<EditText
android:id="#+id/action_list_item_edittext_drinkPercent"
android:text="40"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/action_list_item_edittext_drinkAmount"
android:inputType="number"
android:padding="10dp"/>
<EditText
android:id="#+id/action_list_item_edittext_drinkAmount"
android:text="0.0"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/action_list_item_button_remove"
android:layout_alignBottom="#+id/action_list_item_button_remove"
android:inputType="numberDecimal"
android:width="50dp"
android:padding="10dp" />
<Button
android:id="#+id/action_list_item_button_remove"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="#string/action_list_item_button_remove" />
And code that creates dynamic list:
public class MainActivity extends Activity {
LinearLayout actionList = null;
private Button btnAdd;
private Button btnCalculate;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initActivityElements();
}
private void initActivityElements() {
initAddButton();
initCalculateButton();
}
private void initCalculateButton() {
btnCalculate = (Button) findViewById(R.id.button_count);
btnCalculate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TextView amount = (TextView) findViewById(R.id.action_list_item_edittext_drinkAmount);
//this retrives TextView value from first list
Toast.makeText(getApplicationContext(), amount.getText().toString(),
Toast.LENGTH_SHORT)
.show();
}
});
}
private void initAddButton() {
actionList = (LinearLayout) findViewById(R.id.action_list);
btnAdd = (Button) findViewById(R.id.button_add);
btnAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RelativeLayout listItem = (RelativeLayout) View.inflate(
MainActivity.this, R.layout.action_list_item, null);
TextView name = (TextView) listItem
.findViewById(R.id.action_list_item_edittext_drinkName);
name.setText("Here is the Title " + actionList.getChildCount());
listItem.findViewById(R.id.action_list_item_button_remove)
.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
actionList.removeView((View) v.getParent());
}
});
actionList.addView(listItem);
}
});
}
My problem is that I need to get all data from TextView boxes (Amount, Percent), but I can retrive that data only from first item of a list (look at onClickListener for btnCalculate) and can't figure out how to do it, but tried to add 'unique ids' for view (but that brakes layout, badly), tried setting Tags but again with no luck.
Maybe anyone can give a tip? I bet there is some easy way to do it, but I'm failing to find it and google is no help here.
Thanks

I'm not really sure what exactly you are trying to do but it sounds like you are trying to take in information and populate it into a view. I would recommend having a static text box that takes in your information and builds that into a listview. A good example of how to do that is located here http://developer.android.com/resources/tutorials/notepad/notepad-ex1.html.
