Imagebutton doesnt work in slidinguppanel

Imagebutton doesnt work in slidinguppanel - java

I'm using the umano SlidingUpPanel library and I used an imagebutton in the panel but nothing happens when I click the imagebutton, I tried the imagebutton in another activity which worked perfectly. "next" is supposed to be printed to the logs when the button is pressed. I've searched all over but can't find any solution
Here's my code:
#SuppressLint("Registered")
public class NowPlaying extends Activity {
ImageButton play, pause, play_main, pause_main, next, imgbtn;
private MusicService musicSrv;
#SuppressLint("WrongViewCast")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.now_playing);
play = findViewById(R.id.play_button);
imgbtn = findViewById(R.id.imgbtn);
imgbtn.setOnClickListener(new View.OnClickListener() {
#SuppressLint("ShowToast")
#Override
public void onClick(View v) {
Log.i("oladapos", "next");
}
});
SlidingUpPanelLayout now_playing =
findViewById(R.id.slideup_nowplaying);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
playNext();
}
});
}
//play next
private void playNext(){
musicSrv.playNext();
}
//play previous
private void playPrev(){
musicSrv.playPrev();
}
#Override
public void start() {
}
#Override
public void pause() {
}
#Override
public int getDuration() {
return 0;
}
#Override

return 0;
}

return false;
}

I am unable to refer to things inside my activity, like buttons, and radiogroups

so I am trying to create an activity, and then add onclick listeners to it, but it wont let me refer. So the moment I open this activity in my app, my app crashes, saying 'void android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference'
I have no idea why this is happening. I have correctly names them in accordance with the xml file as well.
Please help.

You didn't call in onCreate method setContentView(R.layout.youractivity). If you didn't, Android doesn't know what to render, so there are no views for you to provide.
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.youractivity);
}

just set your (xml)layout file to setContentView in onCreate()
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_layout);
}

Why won't a textView from a different layout file not properly run setText but textViews from activity_main will?

The program is supposed to run getCurrentLocation and then set the textView "coordinates" to the value of the coordinates called. That text view is part of a pager view that draws from a separate .xml file than the main layout "activity_main".
public class MainActivity extends AppCompatActivity
{
CardAdapter CardAdapter;
String coordinatesFinal;
FusedLocationProviderClient fusedLocationProviderClient;
TextView coordinates;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(MainActivity.this);
if (ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED &&
ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED)
{
getCurrentLocation();
}else
{
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION},100);
}
setupCardItems();
ViewPager2 CardViewPager = findViewById(R.id.cardViewPager);
CardViewPager.setAdapter(CardAdapter);
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults)
{
if (requestCode == 100 & grantResults.length > 0 && (grantResults[0] + grantResults[1]) == PackageManager.PERMISSION_GRANTED)
{
getCurrentLocation();
}else
{
Toast.makeText(getApplicationContext(), "Permission denied.",Toast.LENGTH_SHORT).show();
}
}
#SuppressLint("MissingPermission")
public void getCurrentLocation()
{
coordinates = findViewById(R.id.coordinates);
LocationManager locationManager = (LocationManager) getSystemService
(
Context.LOCATION_SERVICE
);
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) || locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER))
{
fusedLocationProviderClient.getLastLocation().addOnCompleteListener(task ->
{
Location location = task.getResult();
if (location != null)
{
coordinates.setText(location.getLatitude()+", "+location.getLongitude());
}else
{
LocationRequest locationRequest = new LocationRequest().setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY).setInterval(10000).setFastestInterval(1000).setNumUpdates(1);
LocationCallback locationCallback = new LocationCallback()
{
#Override
public void onLocationResult(LocationResult locationResult)
{
Location location1 = locationResult.getLastLocation();
coordinatesFinal = location1.getLatitude()+", "+location1.getLongitude();
}
};
fusedLocationProviderClient.requestLocationUpdates(locationRequest,locationCallback, Looper.myLooper());
}
});
}else

CardAdapter = new CardAdapter(CardItems);
}
}
I have narrowed it down to the line that doesn't work properly:
coordinates.setText(location.getLatitude()+", "+location.getLongitude());
I have tested the exact same line as above, only using a textView from inside activity main, which works just fine. Any help is greatly appreciated.
Edit: The file actually does crash, I mistakenly said it didn't, and I added both .xml Files:

Here's the Console when running a debugger with the breakpoint at
coordinates.setText(location.getLatitude()+", "+location.getLongitude());
The whole console breaks the character limit so here's a document with the console text.
Console Text

if (location != null)
{
// coordinates.setText(location.getLatitude()+", "+location.getLongitude());
cardAdapter.setCoordinates(0 /*the cardItem number you want to update*/, location.getLatitude()+", "+location.getLongitude());
}
Since the coordinates TextView is in your item xml, you will not be able to address it from the root of your MainActivity, but from your item.
Update
Thanks for adding the Adapter code:
Easiest would be to create a method in your adapter like the following:
setCoordinates(int position, String coords) {
holders.get(position).itemView.findViewById(R.id.coordinates).setText(coords);
}
To be able to access the holders on runtime, add the following:
public class CardAdapter extends RecyclerView.Adapter<CardAdapter.cardViewHolder>
{
private List<CardItem> cardItems;
private List<CardViewHolder> holders;
....
#Override
public cardViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
CardViewHolder holder = new cardViewHolder(
LayoutInflater.from(parent.getContext()).inflate(
R.layout.item_container_card, parent, false
)
);
holders.add(holder);
return holder;
}
Another option would be to add the field coordinates to your CardItem and write the setCoordinates method like so:
setCoordinates(int position, String coords) {
cardItems.get(position).setCoordinates(coords);
notifyDataSetChanged(); // to reload the holders, only notifying the specific position will be faster to reload only the changed holder
}

You need to update the adapter items by creating a method in CardAdapter and calling it from main activity as below -
Create this method in your adapter class
public void updateAdapter(List<CardItem> CardItems) {
this.CardItems = CardItems;
notifyDataSetChanged();
}
Replace below line
CardAdapter = new CardAdapter(CardItems);
With this one
CardAdapter.updateAdapter(CardItems);

AndroidStudio 3.6.3 does not generate all BR constants

where are all other constants?!
I have clean-build and rebuild project, as well as invalidated the cache and rebuild the project.

It looks to me that #Bindable needs to be added before every getter

How show a Horizontal Recyclerview - have trouble showing horizontal items

I want to show horizontal items in recyclerview, but I've tried but no work it all, only show me horizontal items with enlarge widh.
In Android Studio show as I want

In Android Studio show me right as I want.
But in runtime, in my mobile the items have full width but wrap content.enter image description here

i think you just add notifyDataSetChanged in your class adapter
public rutaSelAdapter(List<Ruta> l, onItemClick onclick) {
lista = l;
this.onItemClick = onclick;
if (l.size() > 0)
setSelectedItem(l.get(0));
notifyDataSetChanged();
}

In your recyclerview item layout update width of these 2 textviews [tnombre and thorarios] to wrap_content
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:orientation="vertical">
<TextView
android:id="#+id/tnombre"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:inputType="textMultiLine"
android:lines="1"
android:textAppearance="#style/TextAppearance.AppCompat.Medium"
android:textSize="12sp"
android:textStyle="bold"></TextView>
<TextView
android:id="#+id/thorarios"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:textAppearance="#style/TextAppearance.AppCompat.Small"
android:textColor="#color/colorPrimary"
android:textSize="10sp"
android:visibility="gone"></TextView>
</LinearLayout>

If someone else have this issue, I fixed adding this line in the fragment class.
rlista.setHasFixedSize(true);

In the activity I have set a Click event on the floating action button.
I have been debugging and checking to see if the event is ever fired and the click event is never fired. The RegisterActivity code is as follows:
public class RegisterActivity extends AppCompatActivity
{
#BindView(R.id.fb_Cancel)
FloatingActionButton mClose_fb;
#BindView(R.id.btn_Register)
Button mRegister_btn;
#BindView(R.id.cv_RegisterAdd)
CardView mRegister_cv;
#Override
public void onCreate(#Nullable Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
ButterKnife.bind(this);
getSupportActionBar().hide();
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{
showEnterAnimation();
}
mClose_fb.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
animationRevealClose();
}
});
}
public void showEnterAnimation()
{
Transition transition = TransitionInflater.from(this).inflateTransition(R.transition.fabtransition);
getWindow().setSharedElementEnterTransition(transition);
transition.addListener(new Transition.TransitionListener() {
#Override
public void onTransitionStart(Transition transition) {
mRegister_cv.setVisibility(View.GONE);
}
#Override
public void onTransitionEnd(Transition transition) {
transition.removeListener(this);
animateRevealShow();
}
#Override
public void onTransitionCancel(Transition transition) {
}
#Override
public void onTransitionPause(Transition transition) {
}
#Override
public void onTransitionResume(Transition transition) {
}
});
}
public void animationRevealClose()
{
Animator mAnimator = ViewAnimationUtils.createCircularReveal(mRegister_cv,mRegister_cv.getWidth()/2,0, mRegister_cv.getHeight(), mClose_fb.getWidth() / 2);
mAnimator.setDuration(500);
mAnimator.setInterpolator(new AccelerateInterpolator());
mAnimator.addListener(new AnimatorListenerAdapter()
{
#Override
public void onAnimationEnd(Animator animation)
{
mRegister_cv.setVisibility(View.INVISIBLE);
super.onAnimationEnd(animation);
mClose_fb.setImageResource(R.drawable.plus);
RegisterActivity.super.onBackPressed();
}
#Override
public void onAnimationStart(Animator animation) {
super.onAnimationStart(animation);
}
});
}
public void animateRevealShow()
{
Animator mAnimator = ViewAnimationUtils.createCircularReveal(mRegister_cv, mRegister_cv.getWidth()/2,0, mClose_fb.getWidth() / 2, mRegister_cv.getHeight());
mAnimator.setDuration(500);
mAnimator.setInterpolator(new AccelerateDecelerateInterpolator());
mAnimator.addListener(new AnimatorListenerAdapter()
{
#Override
public void onAnimationEnd(Animator animation)
{
super.onAnimationEnd(animation);
}
#Override
public void onAnimationStart(Animator animation)
{
mRegister_cv.setVisibility(View.VISIBLE);
super.onAnimationStart(animation);
}
});
mAnimator.start();
}
#Override
public void onBackPressed() {
animationRevealClose();
}

the method which annotated with #OnClick should be out of onCreate.
#Override
public void onCreate(#Nullable Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
ButterKnife.bind(this);
//--------------------------TODO---------------------//
//----------Set a click event for the floating action button
}
#OnClick({R.id.btn_Login, R.id.fb_Register})
public void onClick(View view)
{
}

#OnClick(R.id.take_photo) void openCameraIntent()
{
openCameraIntent1();
}
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_camera);
initialize();
mFusedLocationClient = LocationServices.getFusedLocationProviderClient(getApplicationContext());
}
private void initialize()
{
btnSavePhoto = findViewById(R.id.btn_save);
photoView = findViewById(R.id.imageView);
photoViewUnuse = findViewById(R.id.imageViewUnuse);
previewPhotoText = findViewById(R.id.preview_text);
btnSavePhoto.setOnClickListener(view -> submitDataToServer());
ButterKnife.bind(this);
}
