Android Studio button going in to wrong page

Android Studio button going in to wrong page - java

In my main page I have 3 different buttons.
Login (loginB)
Create a new account (createB)
Terms of conduct (termsB)
So far it has worked just fine, but for some reason I have now faced a problem with the create new account button. It did go to the right page before but now it goes to a wrong page. It should be going to the CreateAccount -page but it is going to the Menu -page.
I have the java code in the MainActivity were the buttons are here:
public class MainActivity extends AppCompatActivity {
Button loginB;
Button termsB;
Button createB;
EditText emailL,passwordL;
FirebaseAuth fAuth;
ProgressBar progressB;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
createB = findViewById(R.id.createB);
createB.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
openCreateAccount();
}
});
termsB = findViewById(R.id.termsB);
termsB.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
openTermsOfConduct();
}
});
emailL = findViewById(R.id.emailL);
passwordL = findViewById(R.id.passwordL);
fAuth = FirebaseAuth.getInstance();
loginB = findViewById(R.id.loginB);
progressB = findViewById(R.id.progressB);
loginB.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String email = emailL.getText().toString().trim();
String password = passwordL.getText().toString().trim();
if(TextUtils.isEmpty(email)){
emailL.setError("Email is required.");
return;
}
if(TextUtils.isEmpty(password)){
passwordL.setError("Password is required.");
return;
}
if(password.length() <6){
passwordL.setError("Password must be at least 6 characters.");
}
progressB.setVisibility(View.VISIBLE);
//authenticate the user
fAuth.signInWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if(task.isSuccessful()){
Toast.makeText(MainActivity.this, "Logged in successfully", Toast.LENGTH_SHORT).show();
startActivity(new Intent(getApplicationContext(),Menu.class));
}
else{
Toast.makeText(MainActivity.this, "Error " + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
progressB.setVisibility(View.INVISIBLE);
}
}
});
}
});
}
public void openCreateAccount(){
Intent intent = new Intent(this, CreateAccount.class);
startActivity(intent);
}
public void openTermsOfConduct(){
Intent intent = new Intent(this, TermsOfConduct.class);
startActivity(intent);
}
}

I guess you should definitely check(R.layout.activity_create_account2)and whether it is the correct xml for the CreateAccount.java
P.S. While posting questions, always mention the correct name of the xml too.

The following code might be the cause:
if(fAuth.getCurrentUser() != null){
startActivity(new Intent(getApplicationContext(),Menu.class));
finish();
}
Can you check if it's going into the if block?

addimage = (Button) findViewById(R.id.addimage);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
progressBar.setVisibility(View.INVISIBLE);
imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent galleryIntent = new Intent();
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
galleryIntent.setType("image/*");
startActivityForResult(galleryIntent, 1);

} else {
Toast.makeText(getApplicationContext(), "PLEASE SELECT IMAGE", Toast.LENGTH_SHORT).show();

Here is my .Java code for DisciplinasActivity

What am i missing...? if all the other 3 buttons work...why doesnt this one work? (I am a total newbie but i
I really need the help)

Consider your code
button = (Button)findViewById(R.id.button1);
You do not need to explicitly cast widgets anymore unless it's a special case like a RadioButton from a resource ID.
Please check that the button you're clicking is actually the button you set all this up for.
Add
android:clickable="true";
android:focusable="true";
to your buttons in the XML layout.
I'm guessing ConstraintLayout is creating this problem, you shouldn't come across this issue if you use LinearLayout.

In your .xml code for DisciplinasActivity you have some mistakes on the dimensions that you are using:
<GridLayout
...
android:id="#+id/MainGrid"
...
android:layout_marginBottom="#+id/Relative_Layout_Title" <!-- E.G 20dp -->
>
<Button
android:id="#+id/ExitButton"
...
android:layout_marginBottom="#+id/RelativeLayout" <!-- E.G 20dp -->
... />
For margins, padding, etc you have to use a dimension, like dp,in,mm,etc not a reference to other view, or you could use dimmens.xml maybe you are confusing android:layout_marginBottom with android:layout_constraintBottom_toBottomOf or another property. Check for this in all the elements in your .xml
This answer is due to this log that you posted:
ComponentInfo{studying.app.tkappv6/studying.app.tkappv6.Disciplinas_Activity}:
java.lang.UnsupportedOperationException: Can't convert to dimension:
type=0x12

In the MainActivity
Change the to "v.getContext()" istead of "MainActivity.this"
tests.setOnClickListener(new View.OnClickListener() {// menu dos testes
#Override
public void onClick(View v) {
startActivity(new Intent(v.getContext(), Testes_Activity.class));
}
});
createrInfo.setOnClickListener(new View.OnClickListener() {//página sobre a história da app
#Override
public void onClick(View v) {
startActivity(new Intent(v.getContext(), AboutMe_Activity.class));
}
});
pdfdatabase.setOnClickListener(new View.OnClickListener() {//pdf database
#Override
public void onClick(View v) {
startActivity(new Intent(v.getContext(),PDF_Activity.class));
}
});
LogoutBTN.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FirebaseAuth.getInstance().signOut();
startActivity(new Intent(v.getContext(),LoginScreen.class));
finish();
}
});
I was Looking into the code and i've never used this method, but it's strange for me so it's good to pay attention, I think is wrong to set a "Void", if the method is not going to receive any value, but since is a #Override method if it was that way from the beginning you don't need to change;
#Override
public void onSuccess(Void aVoid) {
Toast.makeText(v.getContext(),"Email de verificação enviado.", Toast.LENGTH_SHORT).show();
}
Give a try and let's see if works!

android.widget.ProgressBar cannot be cast to android.widget.RelativeLayout

I'm new to android studio. Currently I'm working on a medlabtut app on android for over 3 months now. I'm having an issue on the login button on the MedLabStartUpScreen that actually supposed to launch the login screen when clicked on. Rather it crashes the app completely and shows a runtimeException at my //Connection Hooks "progressbar = findViewById(R.id.login_progress_bar);" of my login.java class file, that android.widget.ProgressBar cannot be cast to android.widget.RelativeLayout. I need your help please

}

On around line 7 you declare this variable:
RelativeLayout progressbar;
You then correctly go on to initialise this variable with:
progressbar = findViewById(R.id.login_progress_bar);
The issue is that in the xml, the view (widget) with this ID is a ProgressBar, but the type declaration for progressbar in the Java code is RelativeLayout. Your code is therefore trying to cast the ProgressBar in the layout file into a RelativeLayout, which can't be done.
You can fix this by changing the declaration on line 7 to:
ProgressBar progressbar;
(And then adding the necessary import at the top of your Java file: import android.widget.ProgressBar;).
Hope this helped.

You missed initializing btnlogout. Add this line in HomeActivity onCreate before setting View.OnClickListener
btnlogout = findViewById(R.id.btnLogout);

You need to create btnSignUp object before setonlicklistener for button
btnSignUp = findViewById(R.id.btnLogout);

You need to create the btnSignUp object before setonclicklistener.

onButtonClick is never used in source code?

I am writing a simple app which is working fine but the issue I have is that I am using a password condition to trigger a button click if entered correctly.
The issue is that my source code is saying 'onButtonClick' is never used and when I manually press that button in the app, it suddenly force closes and crashes. Anyone know what I am doing wrong. I am extending Activity, at the start of the source code. Should I be extending AppCompatActivity?
public class Gvoice extends Activity implements OnClickListener{
ListView lv1;
static final int check = 1111;
Button b1;
Button b_home;
EditText a1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gvoice);
lv1 = (ListView)findViewById(R.id.LVGVoiceReturn);
b1 = (Button)findViewById(R.id.GVoice);
a1 = (EditText) findViewById(R.id.editTextHome);
b1.setOnClickListener(this);
//This now handles an automatic press of the bVoice button 1 second after the activity is opened
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
b1.callOnClick();
}
}, 1000);
}
public void onButtonClick(View v) {
if (v.getId() == R.id.BHome) {
String str = a1.getText().toString();
//Go to the relevant page if any part of the phrase or word entered in the 'EditText' field contains 'xxx' which is not case sensitive
if (str.toLowerCase().contains("home")) {
Intent userintent = new Intent(Gvoice.this, PocketSphinxActivity.class);
startActivity(userintent);
} else {
Toast.makeText(getApplicationContext(), "Incorrect Information", Toast.LENGTH_SHORT).show();
}
}
}
public void onClick(View v){
Intent i1 = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
i1.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
i1.putExtra(RecognizerIntent.EXTRA_PROMPT, "Please Repeat Again");
startActivityForResult(i1, check);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == check && resultCode == RESULT_OK){
ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
lv1.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, results));
a1.setText((String) lv1.getItemAtPosition(0)); //Get the first phrase in the first row of list view
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
b_home.performClick();
}
}, 500); //Automatically click the 'Blogin' button after 500ms
}
super.onActivityResult(requestCode, resultCode, data);
}
}

You can 4 method handle button click :
method 1 :
public class Mtest extends Activity {
Button b1;
public void onCreate(Bundle savedInstanceState) {
...
Button b1 = (Button) findViewById(R.id.b1);
b1.setOnClickListener(myhandler1);
...
}
View.OnClickListener myhandler1 = new View.OnClickListener() {
public void onClick(View v) {
// it was the 1st button
}
};
}
method 2 :
class MTest extends Activity implements OnClickListener {
public void onCreate(Bundle savedInstanceState) {
...
Button b1 = (Button) findViewById(R.id.b1);
b1.setOnClickListener(this);
...
}
#Override
public void onClick(View v) {
}
}
method 3 in xml and android:onClick="HandleClick" :
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="HandleClick" />
public class MTest extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void HandleClick(View view) {
}
}
method 4 :
public class MTest extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b1 = (Button) findViewById(R.id.b1);
b1.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// do stuff
}
});
}
}

The issue was to do with initially not adding onButtonClick in the xml file and also not correctly assigning the button labels in the java file.
lv1 = (ListView)findViewById(R.id.LVGVoiceReturn);
b1 = (Button)findViewById(R.id.GVoice);
a1 = (EditText) findViewById(R.id.editTextHome);
c1 = (Button)findViewById(R.id.BHome);
b1.setOnClickListener(this);
The following corrects the issues and everything is working fine now. Hope this can help others in the future

Android Studio button going in to wrong page - java

I guess you should definitely check(R.layout.activity_create_account2)and whether it is the correct xml for the CreateAccount.java P.S. While posting questions, always mention the correct name of the xml too.

The following code might be the cause: if(fAuth.getCurrentUser() != null){ startActivity(new Intent(getApplicationContext(),Menu.class)); finish(); } Can you check if it's going into the if block?
