OnClickListener() crash in Fragment - java

For some reason, when I click on the Toolbar(toolbar) and Float button(button) in my app, the OnClickListener () method crashes the snippet and app
Although the ImageButton(OnOff) handler runs and does not crash the fragment

Although this code worked in the main activiti
I don't know why but there are no errors in debug mode

What Kundan has suggested is correct but the fix is much easier.
You don't need this:
final Context context = getActivity();
If you need to gain access to the context in a Fragment you can call requireContext() if you need access to the Activity you can call requireActivity()
So your toast message can become:
Toast.makeText(requireContext(),"lel",Toast.LENGTH_LONG).show();

I think main cause of this issue is
final Context context = getActivity();
which is used in
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context,"lel",Toast.LENGTH_LONG).show();
}
});
please note the getActivity() method returns the current activity with which this fragment is attached. and you are calling while the fragment object is creating before it is attached to activity.
you can change the above code to :
Context context;
and override the method as
#Override
public void onAttach(Context context) {
super.onAttach(context);
this.context = context;
}
Hope this answers your question.

The solution is simple
In your fragment class file, dont create custom function for calling click events rather you can use the android's defaul method by simply implementing them in your class file and then override it. Thats makes the code more simpler and reusable in future.
public class ZnonkiFragment extends Fragment implements View.OnClickListener, View.OnLongClickListener {
private SharedPreferences settings;
private ImageButton OnOff;
private ViewPager viewPager;
private DrawerLayout drawerLayout;
private FloatingActionButton button;
final Context context = getActivity();
private TabLayout tabLayout;
private String ZvonOne, ZvonTwo;
private List<Fragment> list = new ArrayList<>();
private String url;
private Toolbar mToolbar;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_znonki, container, false);
mToolbar = view.findViewById(R.id.toolbar);
mToolbar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_launcher_background));
mToolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, "lel", Toast.LENGTH_LONG).show();
}
});
//...
OnOff = view.findViewById(R.id.onOff);
OnOff.setOnClickListener(this);
OnOff.setOnLongClickListener(this);
button = view.findViewById(R.id.floatingActionButton);
return view;
}
public boolean checkString(String string) {
try {
Integer.parseInt(string);
} catch (Exception e) {
return false;
}
return true;
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.onOff:
//call your onclick function here...
break;
case R.id.floatingActionButton:
//call your onclick function here...
break;
}
}
#Override
public boolean onLongClick(View view) {
switch (view.getId()) {
case R.id.floatingActionButton:
//call your long click function here...
break;
}
return false;
}
}
I have left comments on particular Loc where you can add your code and check it. And the toolbar was crashing due to improper importing of the libraries. If you havent used the androidx library into your gradle file then you can go with simple toolbar which is of "import android.support.v7.widget.Toolbar". This will surely stop your onclick crash on toolbar.
If there is any issue, just let me know. Thank you.

Can't see top toolbar even after calling setSupportActionBar

I'm trying to add a top toolbar, with an options menu in it, in a fragment. Upon running it on the emulator the toolbar doesn't show up.
I have called setSupportActionBar(toolbar), still not sure what's wrong.
EDIT: I've already changed the app theme to NoActionBar.

I have all the necessary imports.
This method will work in Activity. But, here you are trying to do it with Fragment. fragments are sub activities so they have limited scope to do things.
Another thing that may happen, You should change the Activity theme to noActionbar.
By using this, default toolbar will be hide your custom toolbar will be displayed.

Whenever i collapsed bottom sheet the fab button also make itself down with bottom sheet.i need to make my fab button stick to same place whether i expand or collapsed bottom sheet. Thanks in advance.
I need to stick to same layout(Relative layout)
You can't make an UI element from a certain fragment stick around when you're exiting that fragment. If a bottomsheet is collapsed, all its UI elements are collapsed. You can't make on stick around.
You could write a duplicate fab that shows after you closed the bottomsheet in the underlying fragment.
For example, I have this code in my bottomsheet to exit the bottomsheet dialog.
nextButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mBottomSheetDialog.dismiss();
mTimePickerDialogController.show(0, 0, makeTimePickerDialogTag());
}});
When you dismiss the bottomsheet, you could use the following code to make a fab in the underlying fragment appear or disappear.
mFloatingActionButton.hide();
mFloatingActionButton.show();
Edit: A better solution for handling the second fab.
BottomSheetBehavior sheetBehavior;
sheetBehavior = BottomSheetBehavior.from(yourBottomSheet);
sheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
#Override
public void onStateChanged(#NonNull View bottomSheet, int newState) {
switch (newState) {
case BottomSheetBehavior.STATE_HIDDEN:
mFloatingActionButton.show();
case BottomSheetBehavior.STATE_EXPANDED: {
mFloatingActionButton.hide();
}
break;
case BottomSheetBehavior.STATE_COLLAPSED: {
mFloatingActionButton.show();
}
}
}

How to use Helpshift Embeddable Support Fragments Android

I am building an Android app that uses the Helpshift API. It was all working, but I am currently trying to move everything into a TabLayout, using Fragments and an ActionBar. I made a mini app to figure out functionality of the fragments without messing everything else up. I have a home screen where you click a button and it starts the activity containing the TabLayout with the Fragments. I cannot figure out how to make the embeddable support fragments show up in the TabLayout. I'm pretty new to Android, so sorry if my code is not the best. Right now the placeholder is not being replaced in the fragment transaction, and I can't figure out why. I would greatly appreciate any advice! Thank you :) Let me know if I can provide anything else
Here is my main activity class (Helpshift info has been redacted for privacy reasons, hopefully my issue can still be fixed)
public class MainActivity extends AppCompatActivity {
Context mContext;
public ConstraintLayout layout;
Activity goToFragment;
public Button start;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home_screen);
mContext = getApplicationContext();
goToFragment = MainActivity.this;
start = (Button) findViewById(R.id.button);
start.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick (View view) {
launchFragments();
}
});
//HELPSHIFT SET UP
Core.init(All.getInstance());
InstallConfig installConfig = new InstallConfig.Builder()

try {
Core.install(getApplication(),
"****APIKEY*****",
"****DOMAIN*****",
"****APPID******", installConfig);
} catch (InstallException e) {
android.util.Log.e("Helpshift", "install call : ", e);
}
}
private void launchFragments() {
Intent intent1 = new Intent(mContext, HomeTab.class);
intent1.putExtra("fragmentNumber", 0);
startActivity(intent1);
}
}
Here is my ViewPager Adapter class:

}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override

return mFragmentTitleList.get(position);
}
}

}
Fragment faqFragment = new Fragment();
faqFragment = Support.getFAQsFragment(HomeTab.this);
getSupportFragmentManager().beginTransaction().add(R.id.placeholder, faqFragment).commit();
}
}
private void setupViewPager(ViewPager viewPager){
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new FAQTab(), "FAQ");
viewPager.setAdapter(adapter);
}
}
Here is my FAQTab class:
public class FAQTab extends Fragment {

}
#Override

super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

How to disable Touch while video is playing

I am developing a Toddler(kids) app in which I have shown the YouTube videos thumbnails in a recyclerview and whenever the user clicks on any of the listed thumbnails that video plays in full screen YouTube intent( and all the videos after that plays in order automatically). I am succeed in doing so. The problem is now I want to disable the touch screen while the video is playing.

Try with following this will help you
https://stackoverflow.com/a/28429348/7234534
As stated in this thread, this is impossible as you cannot override the home button even if it is soft or hard button. However, you can use third party apps like Untouch which is a very popular one, and can be found in the play store. (Search for Untouch or touch block and it should come up.) You may also check on this blog that discussed some workaround for your issue. Hope this helps!

Add setOnClickListener on Android custom component

one xml file with the layout for the component;
one java class.
Tried to make one, just for practice. Use two progressbars and one button in the XML, and create the class, than tried out in my main activity, worked fine.
But now I'm loking how to set OnClickListener on my button through the activity, and in this part I'm lost.
My loading_button.xml:
<merge
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<RelativeLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="4dp"
android:progress="0"
android:id="#+id/pg_top" />
<Button
android:text="Button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/btn_ok"
android:background="#color/colorPrimary"
android:textColor="#ffffff"
android:layout_below="#+id/pg_top"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="5dp"
android:progress="0"
android:id="#+id/pg_bottom"
android:layout_below="#+id/btn_ok"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</RelativeLayout>
</merge>
Here the LoadingButton.java:
public class LoadingButton extends RelativeLayout{
private ProgressBar pbTop;
private ProgressBar pbBottom;
private Button btnOk;
private int pbTopProgress = 0;
private int pbBottomProgress = 0;
public LoadingButton(Context context, AttributeSet attrs) {
super(context, attrs);
View view = View.inflate(context, R.layout.loading_button, this);
btnOk = (Button) view.findViewById(R.id.btn_ok);
pbTop = (ProgressBar) view.findViewById(R.id.pg_top);
pbBottom = (ProgressBar) view.findViewById(R.id.pg_bottom);
btnOk.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Doing stuff ok
}
});
}// LoadingButton
}
The setOnClickListener in the class works, but how can I set it from my main activity?
MainActivity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// My new component (it's id in activity_main.xml is 'lb')
LoadingButton lb = (LoadingButton) findViewById(R.id.lb);
// QUESTION - how to make something like this with btnOk:
lb.btnOkSetOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Do stuff
}
});
}
}
If this is possible, how?
If not, what is the right approach to make a custom component and set clickListeners on specific element of this component?
Best approach to handle all view click in LoadingButton (For custom view). And create interface.
public class LoadingButton extends RelativeLayout {
public interface OnLoadingButtonClickListener{
void onLoadingButtonClickListener();
}
private ProgressBar pbTop;
private ProgressBar pbBottom;
private Button btnOk;
private int pbTopProgress = 0;
private int pbBottomProgress = 0;
private OnLoadingButtonClickListener mONOnLoadingButtonClickListener;
public LoadingButton(Context context, AttributeSet attrs) {
super(context, attrs);
View view = View.inflate(context, R.layout.loading_button, this);
btnOk = (Button) view.findViewById(R.id.btn_ok);
pbTop = (ProgressBar) view.findViewById(R.id.pg_top);
pbBottom = (ProgressBar) view.findViewById(R.id.pg_bottom);
btnOk.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(mONOnLoadingButtonClickListener != null){
mONOnLoadingButtonClickListener.onLoadingButtonClickListener();
}
}
});
}// LoadingButton
public void setOnLoadingClickListener(OnLoadingButtonClickListener onLoadingClickListener){
mONOnLoadingButtonClickListener = onLoadingClickListener;
}
}
And implement OnLoadingButtonClickListener in your activity.
public class MainActivity extends AppCompatActivity implements LoadingButton.OnLoadingButtonClickListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// My new component (it's id in activity_main.xml is 'lb')
LoadingButton lb = (LoadingButton) findViewById(R.id.lb);
lb.setOnLoadingClickListener(this);
}
#Override
public void onLoadingButtonClickListener() {
//do your stuff on ok button click
}
}
Override setOnClickListener(OnClickListener listener) in your custom Java class. Inside it, write:
btnOk.setOnClickListener(listener);
where listener is an argument of your custom view's setOnClickListener() function.
That will make your whole view clickable and click on your button will be performed. Of couse add android:clickable="true" to your custom view's root layout.
In the component
class Example #JvmOverloads constructor(
context: Context,
attrs: AttributeSet? = null,
defStyle: Int = 0,
defStyleRes: Int = 0) : ConstraintLayout(context, attrs, defStyle) {
var clickListener: () -> Unit = { }
init { }
private fun initListeners() {
binding.button.onClick {
clickListener()
}
}
In the activity / fragment
component.clickListener = { }
And the best part, you can send data on the component and receive it in the landa
