Why SetText not work in OnClick() function

I just know how to use Android Studio Code Yesterday. And I got a problem when I need to Change the text when clicking a button.
But when I text, Its don't work.
Here is my code:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
View bubbleView = getLayoutInflater().inflate(R.layout.bubble_view, null);
Button bubble = (Button) findViewById(R.id.start_bubble);
bubble.setOnClickListener(this);// calling onClick() method
Button predict = (Button) bubbleView.findViewById(R.id.predict);
predict.setOnClickListener(this);
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.start_bubble:
startService(new Intent(getApplicationContext(), SimpleService.class));
case R.id.predict:
View bubbleView = getLayoutInflater().inflate(R.layout.bubble_view, null);
TextView predict_text = (TextView) bubbleView.findViewById(R.id.predict_text);
predict_text.setText("Hi"); // <--- It don't work :(
default:
break;
}
}
}
[EDIT] []
Add some .XML file
Here is my activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"

Do you have any suggested for me ?

I'm not sure why you inflate the "bubble_view.xml" layout in the activity class. But as your question, there are two main methods to make the button clickable. There is a good explanation in your first comment which is done by Mike M. Once you inflate a layout, it will create a new instance.
Fist answer, Assuming you want everything inside the activity.
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private Button bubble;
private Button predict;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initUIViews() // Initialze UI Views
initUIActions() // Initialize Ui Actions
}
private void initUiViews() {
Button bubble = (Button) findViewById(R.id.start_bubble);
Button predict = (Button) bubbleView.findViewById(R.id.predict);
}
private void initUIActions() {
bubble.setOnClickListener(this);// calling onClick() method
predict.setOnClickListener(this);
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.start_bubble:
startService(new Intent(getApplicationContext(), SimpleService.class));
break;
case R.id.predict:
predict_text.setText("Hi");
break;
default:
break;
}
}
}
and restructure your XML layout as follow. There are few ways to restructure these layouts, I'll write the easiest way, but note that this is not the optimal way.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical"
tools:context="com.siddharthks.sampleapp.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Project KHKT"
android:textColor="#AA000000"
android:textSize="21sp" />
<Button
android:id="#+id/start_bubble"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Paste and Predict"
android:textSize="18sp" />
<!-- include bubble layout file -->
<include layout="#layout/bubble_view.xml" />
</LinearLayout>
Other than the include tag you can add the whole code inside to the Activity layout.
The second answer, Assuming you want activity and Service with a bubble view.
If you are looking for a bubble view, You have to create a Bubble service.
Check this answer: Bubble Example
Official Doc: Android Bubble

Try This it will add Your bubble view in your parent and you can perform any action on that particular Layout from main Layout.
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout parent = findViewById(R.id.activity_main); //parent layout.
View childView = LayoutInflater.from(getApplicationContext()).inflate(R.layout.bubble_view,parent,false);
parent.addView(childView);
Button predict = (Button) childView.findViewById(R.id.predict);
TextView predict_text = (TextView) childView.findViewById(R.id.predict_text);
predict.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
predict_text.setText("Hi"); // <--- It don't work :(
}
});
}
}

Add break to the each case statement in the switch.

public class MainActivity extends AppCompatActivity implements View.OnClickListener{
TextView predict_text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button start = (Button) findViewById(R.id.start_bubble);
LinearLayout parent = findViewById(R.id.activity_main);
View childView = LayoutInflater.from(getApplicationContext()).inflate(R.layout.bubble_view, parent, false);
parent.addView(childView);
Button predict = (Button) childView.findViewById(R.id.predict);
predict_text = (TextView) childView.findViewById(R.id.predict_text);
predict.setOnClickListener(this);
start.setOnClickListener(this);
}
#Override
public void onClick(View view) {
switch (view.getId()){
case R.id.predict:
predict_text.setText("Hi");
break;
}
}
}

How add custom navigation view in Android

I have created the layout as attached below, I haven't used any drawerlayout or navigation view. top bar is created using toolbar tag. Now I want to add a navigation view which will invoke once user clicks that hamburger icon. And it should be accessible from other activities as well

You should use the navigation drawer.
You can do this this by creating one common class named BaseActivity and put your code of navigation drawer in this class. and extend your classes/Activities with BaseActivity, where you want to show navigation drawer.
public class BaseActivity extends AppCompatActivity {
public Toolbar toolbar;
ActionBarDrawerToggle mDrawerToggle;
Context context;
private NavigationView navigationView;
private DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
protected boolean useToolbar() {
return true;
}
#Override
public void setContentView(int layoutResID) {
context = this;
DrawerLayout fullView = (DrawerLayout) getLayoutInflater().inflate(R.layout.drawer_main, null);
FrameLayout activityContainer = (FrameLayout) fullView.findViewById(R.id.frame);
getLayoutInflater().inflate(layoutResID, activityContainer, true);
super.setContentView(fullView);
toolbar = (Toolbar) fullView.findViewById(R.id.tool_bar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("");
toolbar.setTitle("");
this.getSupportActionBar().setElevation(0);
getSupportActionBar().setLogo(R.drawable.ic_arrahm);
// toolbar.setLogo(R.drawable.ic_main);
if (useToolbar()) {
setSupportActionBar(toolbar);
setTitle("Places Near Me");
} else {
toolbar.setVisibility(View.GONE);
}
//Initializing NavigationView
navigationView = (NavigationView) findViewById(R.id.navigation_view);
//Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
// This method will trigger on item Click of navigation menu
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
//Checking if the item is in checked state or not, if not make it in checked state
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
//Closing drawer on item click
drawerLayout.closeDrawers();
//Check to see which item was being clicked and perform appropriate action
switch (menuItem.getItemId()) {
case R.id.edit_profile:
return true;
case R.id.change_password:
return true;
default:
Toast.makeText(getApplicationContext(), "Work in progress", Toast.LENGTH_SHORT).show();
return true;
}
}
});
// Initializing Drawer Layout and ActionBarToggle
drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
View header = navigationView.getHeaderView(0);
TextView tvName = (TextView) header.findViewById(R.id.name);
TextView tvEmail = (TextView) header.findViewById(R.id.email);
String name = Preferences.getDataFromStringPreferences(context,Constants.USER_DETAILS, Constants.USER_NAME);
if (name != null) {
tvName.setText(name);
}
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.openDrawer, R.string.closeDrawer) {
#Override
public void onDrawerClosed(View drawerView) {
// Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
//Setting the actionbarToggle to drawer layout
drawerLayout.setDrawerListener(actionBarDrawerToggle);
//calling sync state is necessay or else your hamburger icon wont show up
actionBarDrawerToggle.syncState();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
return super.onPrepareOptionsMenu(menu);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
return mDrawerToggle.onOptionsItemSelected(item);
}
}

ConstraintLayout with ListView doesn't show any data

I've constructed a simple app that consist of a FloatingActionButton and a Snackbar.
When the user clicks the FAB, the actual date should be displayed in main content of app.
Unfortunately, when I'm clicking on the FAB only the Snackbar's working. ListItems doesn't show anything.
What's wrong with my code?
MainActivity.java:
public class MainActivity extends AppCompatActivity {
ArrayList<String> listItems = new ArrayList<String>();
ArrayAdapter<String> adapter;
private ListView myListView;
#Override
protected void onStart() {
super.onStart();
myListView = findViewById(R.id.listView);
adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, listItems);
myListView.setAdapter(adapter);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
addListItem();
Snackbar.make(view, "Item added to list", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private void addListItem(){
SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss MM/dd/yyyy", Locale.US);
listItems.add(dateFormat.format(new Date()));
adapter.notifyDataSetChanged();
}
}

I've not run your code, but it looks pretty good overall. Items are being added to the list and adapter.notifyDataSetChanged(); is being called afterwards. But one small item, you can call add directly on the adapter and it will notify regarding the change.
Platform source code for ArrayAdapter:
public void add(#Nullable T object) {
synchronized (mLock) {
if (mOriginalValues != null) {
mOriginalValues.add(object);
} else {
mObjects.add(object);
}
mObjectsFromResources = false;
}
if (mNotifyOnChange) notifyDataSetChanged();
}
One thing that stands out, the ListView layout does not look right:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".FirstFragment">
<ListView
android:id="#+id/listView"
android:layout_width="0dp"
android:layout_height="0dp"
tools:layout_editor_absoluteX="117dp"
tools:layout_editor_absoluteY="332dp" />
</androidx.constraintlayout.widget.ConstraintLayout>
It has no height or width
There are no constraints
I would suggest changing it to:
android:layout_width="match_parent"
android:layout_height="match_parent"
[Perhaps wrap_content depending on your requirements.]
Also be sure to add some constraints to your ConstraintLayout. If you're not sure, press "infer constraints" at the top of the design editor or use a simpler ViewGroup container. But the ones there now in the "tools:" namespace are only used by the Android Studio "design" tab. They are not meant for the actual device.
For example:
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
