How to get value from Radiogroup and change in database

How to get value from Radiogroup and change in database - java

I am working on an application in android studio with firebase where the user can change user settings such as name, phone number and bio.
I also need the ability to change a selected radio group button value.
The Settings activity class is as follows
public class SettingsActivity extends AppCompatActivity {
private EditText mNameField, mPhoneField, mBio;
private Button mBack, mConfirm;
private RadioGroup mSport;
private ImageView mProfileImage;
private FirebaseAuth mAuth;
private DatabaseReference mUserDatabase;
private String userId, name, phone, bio, sport, profileImageUrl, userSex;
private Uri resultUri;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
mNameField = (EditText) findViewById(R.id.name);
mPhoneField = (EditText) findViewById(R.id.phone);
mBio = (EditText) findViewById(R.id.bio);
mSport = (RadioGroup) findViewById(R.id.sport);
mProfileImage = (ImageView) findViewById(R.id.profileImage);
mBack = (Button) findViewById(R.id.back);
mConfirm = (Button) findViewById(R.id.confirm);
mAuth = FirebaseAuth.getInstance();
userId = mAuth.getCurrentUser().getUid();
mUserDatabase = FirebaseDatabase.getInstance().getReference().child("Users").child(userId);
getUserInfo();
mProfileImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent, 1);
}
});
mConfirm.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
saveUserInformation();
}
});
mBack.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
return;
}
});
}
private void getUserInfo() {
mUserDatabase.addListenerForSingleValueEvent(new ValueEventListener() {
#RequiresApi(api = Build.VERSION_CODES.O)
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
if(dataSnapshot.exists() && dataSnapshot.getChildrenCount()>0){
Map<String, Object> map = (Map<String, Object>) dataSnapshot.getValue();
if(map.get("name")!=null){
name = map.get("name").toString();
mNameField.setText(name);
}
if(map.get("phone")!=null){
phone = map.get("phone").toString();
mPhoneField.setText(phone);
}
if(map.get("bio")!=null){
bio = map.get("bio").toString();
mBio.setText(bio);
}
if(map.get("sport")!=null){
}
if(map.get("sex")!=null){
userSex = map.get("sex").toString();
}
if(map.get("sport") !=null){
}
Glide.clear(mProfileImage);
if(map.get("profileImageUrl")!=null){
profileImageUrl = map.get("profileImageUrl").toString();
switch(profileImageUrl){
case "default":
Glide.with(getApplication()).load(R.mipmap.default_app_image).into(mProfileImage);
break;
default:
Glide.with(getApplication()).load(profileImageUrl).into(mProfileImage);
break;
}
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}
private void saveUserInformation() {
name = mNameField.getText().toString();
phone = mPhoneField.getText().toString();
bio = mBio.getText().toString();
int selectSport = mSport.getCheckedRadioButtonId();
final RadioButton sportButton = (RadioButton) findViewById(selectSport);
if(sportButton.getText() == null){
return;
}
Map userInfo = new HashMap();
userInfo.put("name", name);
userInfo.put("phone", phone);
userInfo.put("bio", bio);
userInfo.put("sport",sport);
mUserDatabase.updateChildren(userInfo);
if(resultUri != null){
StorageReference filepath = FirebaseStorage.getInstance().getReference().child("profileImages").child(userId);
Bitmap bitmap = null;
try {

} catch (IOException e) {
e.printStackTrace();
}
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos);
byte[] data = baos.toByteArray();
UploadTask uploadTask = filepath.putBytes(data);
uploadTask.addOnFailureListener(new OnFailureListener() {

return;
}
});
}else{
finish();
}
}
#Override

How would I get the new selected value of the radio group and save it to the database?

You should be able to do something like this:
int radioButtonId = mSport.getCheckedRadioButtonId();
View radioButton = mSport.findViewById(radioButtonId);
int idx = mSport.indexOfChild(radioButton);
To get selected RadioButton Text in a RadioGroup, please use the following code:
RadioButton rb = (RadioButton) mSport.getChildAt(idx);
String selectedText = rb.getText().toString();
But note, this code will work only if the radio buttons are direct children of your RadioGroup. So you need to remove those "LinearLayouts". In fact, there is no need to use those layouts at all. You can set the orientation of your RadioGroup to "vertical", in your .XML file, using the following line of code:
android:orientation="vertical"

startActivity(intent, options.toBundle());

startActivity(intent);
}
}
}

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.

Instead of passing the data to the Profile activity use the GoogleSignIn.getLastSignedInAccount(getActivity()); method to get user profile data.
Replace your,
Intent i = getIntent();
final String i_name, i_email, i_url;
i_name = i.getStringExtra("p_name");
i_email = i.getStringExtra("p_email");
i_url = i.getStringExtra("p_url");
with the following code,
GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(getActivity());
if (acct != null) {
String i_name = acct.getDisplayName();
String i_email = acct.getEmail();
Uri i_url = acct.getPhotoUrl();
}

Android app is crashing after clicking button

Android Studio is showing open app again app-crash when I click sign up button
The app is running fine but when I click the sign up button it crashes, also want to start new activity after sign up but the error is com
I think there is some problem with button click listener or validation code but don't know where this error is coming from.
following is my java file code:

Well for starters you are re-assigning the Input fields here, overwriting the previous one... I'm pretty sure the issue is because of this.
signupInputName = (EditText) findViewById(R.id.signup_input_name);
signupInputName = (EditText) findViewById(R.id.signup_input_email);
signupInputName = (EditText) findViewById(R.id.signup_input_Password);
signupInputName = (EditText) findViewById(R.id.signup_input_DOB);
signupInputLayoutName = (TextInputLayout) findViewById(R.id.sign_up_name);
signupInputLayoutName = (TextInputLayout) findViewById(R.id.sign_up_email);
signupInputLayoutName = (TextInputLayout) findViewById(R.id.sign_up_DOB);
The very first thing your code does after onCreate() is checkEmail(), and as I stated above, there is no R.id.signup_input_email assigned to signupInputEmail.
Your code will throw an exception here since checkEmail() refers to a NULL variable.
if (!checkEmail()) { ... }

7 Buttons, 3 AsyncTasks, 1 Activity, and a nightmare [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.

Just when I thought I had this one cinched, I realized that I can only use the buttons in the activity in the same sequence they are written in the Activity.java (Ex: Cannot execute button 5 press, until 1,2,3,and 4 have all been pressed!)
How do I fix this?

Menu does not show either! All help appreciated!

You need to override the method onCreateOptionsMenu. I give you the sample code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(group1Id,searchBtnId ,searchBtnId,"Search");
menu.add(group2Id,scheduleBtnId ,scheduleBtnId,R.string.schedule);
menu.add(group2Id,playBtnId ,playBtnId,"Play");
menu.add(group2Id,stopBtnId ,stopBtnId,R.string.stop);
return super.onCreateOptionsMenu(menu);
}

Why not create one Async class that can do 4 different types of downloads? This class would take as parameters: the button, the textview, and the url. Then you have 1/4 as much code. In the async, make all the buttons non clickable (setClickable(false)).
At any rate, you need to assign an onclicklistener for all the buttons at OnCreate(). You could make a custom class and switch on the button type, or just do the individualized anonymous class route.
