How to make messages appear on different sides?

I make a chat app using a video tutorial, but this tutorial does not show how to make messages from different people appear on different sides. The sender and receiver see all messages on the left. Could you please give some advices on this? Thanks in advance.
Now it looks like this
Main code
public class MainActivity extends AppCompatActivity {
private static int SIGN_IN_CODE=1;
private RelativeLayout activity_main;
private FirebaseListAdapter<Message> adapter;
private FloatingActionButton sendBtn;
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==SIGN_IN_CODE) {
if(requestCode == RESULT_OK) {
Snackbar.make(activity_main, "You are authorized", Snackbar.LENGTH_LONG).show();
displayAllMessages();
} else {
Snackbar.make(activity_main, "You are not authorized", Snackbar.LENGTH_LONG).show();
finish();
}
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
activity_main=findViewById(R.id.activity_main);
sendBtn = findViewById(R.id.btnSend);
sendBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
EditText textField = findViewById(R.id.messageField);
if(textField.getText().toString().equals(""))
return;
FirebaseDatabase.getInstance().getReference().push().setValue(
new Message(
FirebaseAuth.getInstance().getCurrentUser().getEmail(),
textField.getText().toString()));
textField.setText("");
}
});
//Пользователь ещё не авторизован
if (FirebaseAuth.getInstance().getCurrentUser()==null)
startActivityForResult(AuthUI.getInstance().createSignInIntentBuilder().build(), SIGN_IN_CODE);
//Пользователь авторизован
else {
Snackbar.make(activity_main, "You are authorized", Snackbar.LENGTH_LONG).show();
displayAllMessages();
}
}
#Override
protected void onStart() {
super.onStart();
adapter.startListening();
}
private void displayAllMessages() {
ListView listOfMessages = findViewById(R.id.list_of_messages);
FirebaseListOptions<Message> options =
new FirebaseListOptions.Builder<Message>()
.setQuery(FirebaseDatabase.getInstance().getReference(), Message.class)
.setLayout(R.layout.list_item)
.build();
adapter = new FirebaseListAdapter<Message>(options){
#Override
protected void populateView(View v, Message model, int position) {
TextView mess_user, mess_time;
BubbleTextView mess_text;
mess_user = v.findViewById(R.id.message_user);
mess_time = v.findViewById(R.id.message_time);
mess_text = v.findViewById(R.id.message_text);
mess_user.setText(model.getUserName());
mess_text.setText(model.getTextMessage());
mess_time.setText(DateFormat.format("dd-MM-yyyy HH:mm:ss", model.getMessageTime()));
}
};
listOfMessages.setAdapter(adapter);
}
#Override
protected void onStop() {
super.onStop();
adapter.stopListening();
}
}
Message Class
public class Message {
private String UserName;
private String TextMessage;
private long MessageTime;
public Message() {}
public Message (String UserName, String TextMessage){
this.UserName = UserName;
this.TextMessage = TextMessage;
this.MessageTime = new Date().getTime();
}
public String getUserName() {
return UserName;
}
public void setUserName(String userName) {
UserName = userName;
}
public String getTextMessage() {
return TextMessage;
}
public void setTextMessage(String textMessage) {
TextMessage = textMessage;
}
public long getMessageTime() {
return MessageTime;
}
public void setMessageTime(long messageTime) {
MessageTime = messageTime;
}
}

Try adding layout_gravity attribute in your BubbleTextView when you need this like this:
android:layout_gravity="right"

Every user will have a unique email - Let say here in the example - d#mail.ru is your email. You need to add user logic to dynamically check to decide whether you want a bubble test layout to be LEFT or RIGHT.
Update the message bubble layout.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/parentLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:id="#+id/message_user"
android:textStyle="normal|bold"

android:layout_width="wrap_content"

app:angle="10dp"
app:arrowWidth="8dp"
app:arrowHeight="10dp"
app:arrowPosition="10dp"
app:bubbleColor="#03dac5"
/>
</RelativeLayout>
Adapter code:- you can update as you need either LEFT or RIGHT.
adapter = new FirebaseListAdapter<Message>(options){
#Override
protected void populateView(View v, Message model, int position) {
TextView mess_user, mess_time;
BubbleTextView mess_text;
RelativeLayout Layout = v.findViewById(R.id.parentlayout);
mess_user = v.findViewById(R.id.message_user);
mess_time = v.findViewById(R.id.message_time);
mess_text = v.findViewById(R.id.message_text);
mess_user.setText(model.getUserName());
mess_text.setText(model.getTextMessage());
mess_time.setText(DateFormat.format("dd-MM-yyyy HH:mm:ss", model.getMessageTime()));
if(!model.getUserName().equals("d#mail.ru")) {
mess_text.setGravity(Gravity.LEFT)
} else {
mess_text.setGravity(Gravity.RIGHT)
}
}
};

TextView is not selectable with ontouchListener

I have implemented ontouchListener in my activity to detect swipes left and right. However, enabling this feature stopped me from being able to make my text selectable and accordingly getting the default android text selection cursor, menu.
After many trials, now i can perfectly call the onLongClick() method when long clicking the textView. However, still the text is not selectable. also, whenever I disable the swipe detection, the Text selection works perfectly.
public class PreviewActivity extends AppCompatActivity
{
TextView question;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_preview);
question = (TextView)findViewById(R.id.question);
question.setTextSize(TextViewSize);
question.setTextIsSelectable(true);
question.setLongClickable(true);
question.setFocusableInTouchMode(true);
View prev_act = (View) findViewById(R.id.question);
prev_act.setOnTouchListener(new OnSwipeTouchListener(this) {
#Override public void onSwipeLeft() {
if(RowIndex>0){
Qtitle = ListItems.get(RowIndex-1);
Query();
//text = Query();
//question.setText(text);
questionSC.scrollTo(0,0);
RowIndex--;
}
}
#Override public void onSwipeRight() {
if(RowIndex<ListItems.size()-1){
Qtitle = ListItems.get(RowIndex+1);
Query();
//text = Query();
//question.setText(text);
questionSC.scrollTo(0,0);
RowIndex++;
}
}
#Override public void onLongClick() {
Log.v(this.toString(), "Long click.");
question.setCursorVisible(true);
question.performLongClick();
}
});
}
And the OnSwipeTouchListener class is as the following:
public class OnSwipeTouchListener implements OnTouchListener {
private final GestureDetector gestureDetector;
public OnSwipeTouchListener (Context ctx){
gestureDetector = new GestureDetector(ctx, new GestureListener());
}
#Override public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
private final class GestureListener extends SimpleOnGestureListener {
private static final int SWIPE_THRESHOLD = 250;
private static final int SWIPE_VELOCITY_THRESHOLD = 200;
#Override
public void onLongPress(MotionEvent e) {
onLongClick();
super.onLongPress(e);
}
#Override
public boolean onDown(MotionEvent e) {
return true;
}
#Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
boolean result = false;
try {
float diffY = e2.getY() - e1.getY();
float diffX = e2.getX() - e1.getX();
if (Math.abs(diffX) > Math.abs(diffY)) {
if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (diffX > 0) {
onSwipeRight();
} else {
onSwipeLeft();
}
result = true;
}
}
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
}
public void onSwipeRight() {
}
public void onSwipeLeft() {
}
public void onSwipeTop() {
}
public void onSwipeBottom() {
}
public void onLongClick() {
}
}
I want to be able to select a portion (text) from the TextView and having the swipe detector along it.

After trying for a while this is what worked highlighting and selecting text enabling copy,paste,selectall ... etc
you will need to add onTouch snippet in the prev_act.setOnTouchListener(new OnSwipeTouchListener(this) {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if (event.getAction() == MotionEvent.ACTION_DOWN) {
//do stuff here
Log.i("clicking", "onActionDown");
}else if(event.getAction() == MotionEvent.ACTION_UP) {
question.performLongClick();
}
return false;
}
#Override public void onLongClick() {
}

The answer was very simple:
#Override
public boolean onDown(MotionEvent e) {
return false;
}
I had to set the onDown() to return false.

Strange behavior in app that wont play sound unless a Toast line is inserted

So I'm making a xylophone app and it weirdly works(plays sound) only when inserted a seemingly unimportant line which Toasts the loaded soundID and I'm not sure what to make of it.If you remove the Toast line the onClick function wont play sound at all.
The aforementioned line is in the onClick function within the for loop
public class MainActivity extends AppCompatActivity {
// Helpful Constants
private final int NR_OF_SIMULTANEOUS_SOUNDS = 7;
private final float LEFT_VOLUME = 1.0f;
private final float RIGHT_VOLUME = 1.0f;
private final int NO_LOOP = 0;
private final int PRIORITY = 0;
private final float NORMAL_PLAY_RATE = 1.0f;
//Adding IDs here
int[] xyloIDs =
{
R.id.c_key,
R.id.d_key,
R.id.e_key,
R.id.f_key,
R.id.g_key,
R.id.a_key,
R.id.b_key,
};
int[] soundIDs =
{
R.raw.note1_c,
R.raw.note2_d,
R.raw.note3_e,
R.raw.note4_f,
R.raw.note5_g,
R.raw.note6_a,
R.raw.note7_b,
};
private SoundPool mSoundPool;
private int mSoundId;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Creating a new SoundPool
mSoundPool = new SoundPool(NR_OF_SIMULTANEOUS_SOUNDS, AudioManager.STREAM_MUSIC, 0);
}
public void onClick(View view)
{
for(int i=0; i < xyloIDs.length ; i++ )
{
if(view.getId() == xyloIDs[i]) {
//Load and get the IDs to identify the sounds
mSoundId = mSoundPool.load(this, soundIDs[i], 1);
Toast.makeText(this, String.valueOf(mSoundId) , Toast.LENGTH_SHORT).show();
mSoundPool.play(mSoundId, LEFT_VOLUME, RIGHT_VOLUME, PRIORITY, NO_LOOP, NORMAL_PLAY_RATE);
}
}
}
And here is my activity_main.xml if it makes any difference

May be your file on loading so it can not be play,
the Toasts make your load and play delay more.
You may need implement setOnLoadCompleteListener and call the play inside the listener.
mSoundPool.setOnLoadCompleteListener(new OnLoadCompleteListener()
{
#Override
public void onLoadComplete(SoundPool soundPool, int sampleId,int status) {
mSoundPool.play(sampleId, LEFT_VOLUME, RIGHT_VOLUME, PRIORITY, NO_LOOP, NORMAL_PLAY_RATE);
}
});

App Crashes when using setVisibility

As the title says,

Anyone help appreciated to fix this issue, Thanks

Your startLabel is null (copy paste problem?^^). Replace this:
scoreLabel = (TextView) findViewById(R.id.startLabel);
with this:
startLabel = (TextView) findViewById(R.id.startLabel);

How to hide part of layout when editText is selected

<LinearLayout android:id="#+id/InnerRelativeLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true">
<Button android:id="#+id/okBtn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="Ok"/>
<Button android:id="#+id/stornoBtn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="Storno" />
</LinearLayout>
Now when the editText is clicked to type some value i need to hide that linearLayout android:id="#+id/InnerRelativeLayout" because otherwise it is still visible above the keyboard.

Need to set a FocusChangeListener to the EditText which triggers whenever focus changes on that EditText as follow:
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
// hide relative layout
} else {
// show relative layout
}
}
});

It is not actually that simple, here is my solution how I got it working.
First Need to create MyEditText.java
public class MyEditText extends EditText {
private KeyImeChange keyImeChangeListener;
public MyEditText(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
}
public void setKeyImeChangeListener(KeyImeChange keyImeChange){
keyImeChangeListener = keyImeChange;
}
public interface KeyImeChange {
public boolean onKeyIme(int keyCode, KeyEvent keyEvent);
}
#Override
public boolean onKeyPreIme (int keyCode, KeyEvent keyEvent){
if(keyImeChangeListener != null){
return keyImeChangeListener.onKeyIme(keyCode, keyEvent);
}
return false;
}
}
Then layout.xml, change following
<EditText
android:id="#+id/tariffName"
android:gravity="right"
android:padding="3dip" />
Into
<!-- change yourapp -->
<com.yourapp.MyEditText
android:id="#+id/tariffName"
android:gravity="right"
android:padding="3dip" />
Add also android:focusable="true" to your LinearLayout
<LinearLayout android:id="#+id/InnerRelativeLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:focusable="true">
Then put into your activity like MainActivity.java,
import fi.hgs.apps.MyEditText.KeyImeChange;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
removeFocus();
MyEditText myEditText = (MyEditText) findViewById(R.id.tariffName);
myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus) {
showLinearLayout();
} else {
hideLinearLayout();
}
}
});
myEditText.setKeyImeChangeListener(new KeyImeChange() {
#Override
public boolean onKeyIme(int keyCode, KeyEvent event) {
if (KeyEvent.KEYCODE_BACK == event.getKeyCode()) {
removeFocus();
}
return false;
}
});
}
Add also these to do the actual job.
public void removeFocus() {
LinearLayout linearLayout = (LinearLayout)findViewById(R.id.InnerRelativeLayout);
linearLayout.requestFocus();
}
public void showLinearLayout() {
LinearLayout linearLayout = (LinearLayout)findViewById(R.id.InnerRelativeLayout);
linearLayout.setVisibility(View.VISIBLE);
}
public void hideLinearLayout() {
LinearLayout linearLayout = (LinearLayout)findViewById(R.id.InnerRelativeLayout);
linearLayout.setVisibility(View.INVISIBLE);
}
