Not able to click the logout and posy buttons

I have tried checking if any layout is overlapping or not. I have tried adding more space between the button and the border nothing seems to work. I'm not able to see where am I missing out
This is the activity where I'm trying to add setonclicklistenr:
public class addPost extends AppCompatActivity {
ImageView picgal,postt;
EditText descrip,compName;
Button pst,logout;
FirebaseAuth auth;
FirebaseStorage storage;
FirebaseDatabase database;
Uri uri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_post);
picgal = findViewById(R.id.addpic);
descrip = findViewById(R.id.postDescription);
logout = findViewById(R.id.lgout);
compName = findViewById(R.id.comm);
auth = FirebaseAuth.getInstance();
storage = FirebaseStorage.getInstance();
logout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
auth.signOut();
startActivity(new Intent(addPost.this,postActivity.class));
}
});

I can See You are setting "enabled=false" in logout Button could you remove that part or replace with "enabled=true"...I will work if you do so ..please try

sending data of two fragments to firebase (Fragment wise or in one go)

I have two fragments in one activity. In the first fragment, I have fields like name, email, gender and phone number and by the next button replace with second fragment and on the second fragment, I have a password and confirm password fields. Now I want to send data to firebase fragment-wise or send data of two fragments at one time(by pressing the register button which is on the second fragment).but did not know how to do that

public class FragmentB extend Fragment implements FragmentInterface{}
xxxActivity:
FragmentInterface fia = (FragmentInterface)FragmentA;
FragmentInterface fib = (FragmentInterface)FragmentB;
get Field:
String name = fia.getName();
String pw = fib.getPassword();
BroadcastReceiver
Global singleton

you have to use bundle in fragment to pass data from one fragment to another
Without Arch. Component...
send data to another fragment
Fragment fragment = new ProductdetailFragment();
FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.frame_main,fragment);
transaction.addToBackStack(null);
transaction.commit();
Bundle bundle = new Bundle();
bundle.putString("product_id","value");
bundle.putString("product_name","value");
bundle.putString("price","value");
bundle.putString("product_desc","value");
bundle.putString("product_image",productmodels.get(position).getProduct_image());
fragment.setArguments(bundle);
get data from the previous fragment. for getting data, you have to use key of apply of the previous fragment.do not mismatch key argument
Bundle bundle = getArguments();
String product_id = bundle.getString("product_id");
String name = bundle.getString("product_name");
String price = bundle.getString("price");
String description = bundle.getString("product_desc");
String imageurl = bundle.getString("product_image");
Second Way if You use Navigation Arch. Component
Bundle bundle = new Bundle();
bundle.putString("amount", amount);
Navigation.findNavController(view).navigate(R.id.confirmationAction, bundle);

In my Activity java code has this button click code
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_download);
inputURl = findViewById(R.id.editUrl);
editUrlinsta = findViewById(R.id.editUrli);
BtnDownload = (Button) findViewById(R.id.button_download);
downloadinsta = (Button) findViewById(R.id.button_insta);
BtnDownload.setOnClickListener(this);
downloadinsta.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()){
case R.id.button_download:
try{
final FacebookDownloader downloaders = new FacebookDownloader(Download.this,inputURl.getText().toString());
downloaders.DownloadVideo();
inputURl.getText().clear();
} catch(Exception e) {}
break;
case R.id.button_insta:
final InstaDownloader downloaderInsta = new InstaDownloader(Download.this,editUrlinsta.getText().toString());
downloaderInsta.DownloadVideo();
editUrlinsta.getText().clear();
break;
default:
break;
}
}
The problem is The first button which I have named button_download is working as expected. But the second button button_insta not working as expected. what I want to do, is When one of the buttons clicks, getting data from EditText. The button_download works fine. the button_insta is not working fine.
I couldn't get value from editUrli when the button click. But same code works for button_download and editUrl

Try to separate those button click function like so :
BtnDownload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try{
final FacebookDownloader downloaders = new FacebookDownloader(Download.this,inputURl.getText().toString());
downloaders.DownloadVideo();
inputURl.getText().clear();
} catch(Exception e) {}
}
});
downloadinsta.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final InstaDownloader downloaderInsta = new InstaDownloader(Download.this,editUrlinsta.getText().toString());
downloaderInsta.DownloadVideo();
editUrlinsta.getText().clear();
}
});

Why is my Text Change Listener not working?

Why is my "addTextChangedListener" on android not working? Here is my code:

I don't get any error. On debugging, it doesn't stop on any of the overrides.

You can set in tow way
First Way:
EditText et_auto_complete_edit_text;
et_auto_complete_edit_text = findViewById(R.id.et_auto_complete_edit_text);
et_auto_complete_edit_text.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
s.toString()
}
});
XML:
<EditText
android:id="#+id/et_auto_complete_edit_text"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_weight="8"
android:background="#color/gray_light_EA"
android:drawableRight="#mipmap/ic_search_new"
android:drawablePadding="#dimen/margin5dp"
android:hint="Search here"
android:inputType="text"
android:maxLines="1"
android:padding="10dp"
android:textColor="#color/black"
android:textColorHint="#color/grey"
android:visibility="visible" />
Second Way :
SearchView search;
search = findViewById(R.id.search);
search.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
fetchData(query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
//collectionProductsListAdapter.getFilter().filter(newText);
return false;
}
});
search.setOnSearchClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
search.setOnCloseListener(new SearchView.OnCloseListener() {
#Override
public boolean onClose() {
return false;
}
});
XML:
<androidx.appcompat.widget.SearchView
xmlns:n2="http://schemas.android.com/tools"
android:id="#+id/search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
n2:searchIcon="#mipmap/ic_et_search" />
Hope this may help you first way is more easy.

Try changing it to EditText
<android.support.design.widget.TextInputLayout
android:id="#+id/editText"
android:layout_width="0dp"
android:layout_height="50dp"
android:layout_marginTop="16dp"
android:ems="10"
android:hint="Km"
app:layout_constraintEnd_toEndOf="#+id/button_prevDestination"
app:layout_constraintStart_toStartOf="#+id/button_prevDestination"
app:layout_constraintTop_toBottomOf="#+id/textView_currentPostDestination">
<EditText
android:id="#+id/textKm"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.TextInputLayout>
Working fine in my code.

Application stops when i change everything in a button/textview except the Text

im using 2 Android Books and android-studio to get into the materia but now im stuck.
If i try to change .clickable(false), .setenabled(false) or even the color in Java, my programm stops. It runs fluent with every gimmick im implementing but if i try to enable (first state disabled) the checkboxes/buttons, when someone clicks on the "startbutton", my app closes.
Note about the ammount of Textviews and checkboxes: Im about to check out the mainfunctions and make it in the 1.0 in a scrollable activity with an objectarray. atm all these textviews are only there to get me a hint how big this app can be. It´s a quizapp for exams about health and medicine. It is possible that there is 1 question 10 subquestions and 10 answers or 1 questions, 0 subquestions and only 2 answers. Every Exam has about 60 Questions. BUT i can´t do this cause when i disable one single checkbox or setVisebility(false) my App stops.
My suggestions:
to open a "getCurentState()" method in the xml File
create a new xml file with one "true" and a "false" varable and ref them in the main xml document setclickable="#.../currentState"
ivé heard about xsl but how? :D

If someone encounters this problem this should help you, in my case it worked.
instead of
listview.setVisibility(true);
do this:
listview.setVisibility(View.VISIBLE);
same thing for Buttons,Textviews or Checkboxes.
checkBox.setChecked(true); //that won´t work if you add dynamically in a listview or linearlayout
checkBox.toggle(); // will do the job, maybe it will work with .setChecked(!ischecked); but i had more problems with it
As far as i have worked with android-studio, i recognised that if you use true/false (boolean) or a fixed number (even if the settings are 1 and 0) for colors in coding, your app will have many problems and won´t run fluent. In an activity you need to speak to the Parentclass (View) and select the variable viá dot. View.VISIBLE (which is an int) View.INVISIBLE (which is also an int)
Hope this will help someone, cause i didn´t got an propper solution for my problem. Android requiers an int instead of a boolean, even if the constructor want´s a boolean. Crazy stuff.
