Not able to click the logout and posy buttons

Not able to click the logout and posy buttons - java

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));
}
});
This is the xml file:

OUTPUT

You are referring to the R.id.Username component which is the SIGN UP text and you are casting the fields as TextViews instead of EditTexts.
Change your variables to:
EditText Username=(EditText) findViewById(R.id.edittext);
EditText password=(EditText) findViewById(R.id.password);

You are getting the text from the wrong reference, Change the below code to later.
TextView Username=(TextView) findViewById(R.id.Username);
to
TextView Username=(TextView) findViewById(R.id.edittext);

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

Interface;
interface:

}
Fragment:
public class FragmentA extend Fragment implements FragmentInterface{}
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

}
#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:hint="Search here"
android:inputType="text"
android:maxLines="1"
android:padding="10dp"

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.

Android actionbar/toolbar disappears after writing to edittext [duplicate]

This question already has answers here:
Android Toolbar moves up when keyboard appears
(17 answers)
Closed 4 years ago.
I'm stuck at this. I have an app where I have several pages made as fragments. Every page is good except the last one where when I tap on editText, action bar disappears and when I unfocus it, action bar didn't show up back.
I've tried changing appTheme to all kind of themes but they didn't change anything, most of them forced app to crash.
Here is my layout of that page
