I got illegalStateException when I compiled my snackbar. The result of App is that I can execute the first button but once I tried to use my second button the app will crush.
The code and error message are shown like this:
public void callIntent(View view) {
Intent intent = null;
switch (view.getId()) {
case R.id.ZhaoDisplay:
Toast toast = Toast.makeText(getApplicationContext(),
"Zhao Wang, 991556434; Website Name: Amazon", Toast.LENGTH_SHORT);
toast.show();
intent = new Intent(Intent.ACTION_VIEW,
Uri.parse("https://www.amazon.ca"));
startActivity(intent);
break;
case R.id.WangDisplay:
intent = new Intent(this, WangActivity.class);
//TextMulti
editInput = (EditText)findViewById(R.id.TextMulti);
String userInput = editInput.getText().toString();
intent.putExtra("valueFromUser", userInput);
Snackbar snackbar = null;
snackbar = Snackbar.make(findViewById(R.id.content),
"My Second Screen_Zhao Wang 991556434", 10);
snackbar.show();
startActivity(intent);
break;
default:
break;
}

I tried to put snackbar code part to my second activity and compile it but it showed the same error. May I ask for assistance about this? Thanks.
The issue is with passing a wrong view for the snackbar make method, instead try the following
snackbar = Snackbar.make(findViewById(android.R.id.content),
"My Second Screen_Zhao Wang 991556434", 10);
snackbar.show();

I am creating an simple app where user types any address and gets suggestions, after clicking on any suggestion it will be displayed in a textview.
Autcomplete initialization:
try {
val fields = listOf(
Place.Field.ID, Place.Field.NAME, Place.Field.LAT_LNG,
Place.Field.ADDRESS)
val intent=Autocomplete.IntentBuilder(AutocompleteActivityMode.FULLSCREEN, fields).build(this)
startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE)
}catch (e: Exception){
e.printStackTrace()
}
onActivityResult() code:
if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE){
val place = Autocomplete.getPlaceFromIntent(data!!)
et_location.setText(place.address)
mLatitude=place.latLng!!.latitude
mLongitude=place.latLng!!.longitude
}
The problem is that whenever I type a single alphabet in the Autocomplete, the application crashes saying Intent expected to contain a Place, but doesn't.
What is the problem with my code?
This question didn't help me as I want place.address to return a string address.
logcat:

I am trying to initialize TextView in Kotlin as following
val textSelectedFood = findViewById<TextView>(R.id.textSelectedFood) as TextView
I also tried this
val textSelectedFood: TextView = findViewById<TextView>(R.id.textSelectedFood) as TextView
And also this
val textSelectedFood: TextView = findViewById(R.id.textSelectedFood) as TextView
And this
val textSelectedFood: TextView = findViewById<TextView>(R.id.textSelectedFood)
But still getting following errors. Don't know why

I got hints from this question.
but the code changed a lot over the year.
That's why I am writing the current solution code in the below which solved my problem.
private lateinit var textSelectedFood: TextView // withoud lateinit code will show error
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
textSelectedFood = findViewById(R.id.textSelectedFood)
}
If you do not have to "findViewById" have many better and safer options:
1.synthetic (deprecated)
Call the view directly in your code.
2.view binding
For more information check this link:https://developer.android.com/topic/libraries/view-binding
This technique is old now, just use "View binding".
Or you can just call the view by it's id and that'll be it.
In your case:
textSelectedFood.text = "Example of doing something"
How do I call setText() using float data type? I have already tried this
if (response.isSuccessful) {
val destination = response.body()
destination?.let {
client_names.setText(destination.client_name)
product_names.setText(destination.product_name)
amounts.setText(String.valueOf(destination.amount)) ----->
prices.setText(String.valueOf(destination.price)) ----->
comments.setText(destination.comment)
collapsing_toolbar.title = destination.client_name + destination.product_name
}
I have tried this answer from this link

If you don't need any formatting just do:
setText("${destination.amount}")

public void Loginbutton(View v) {
/* Get entered fields data. */
String email = field_email.getText().toString();
String password = field_password.getText().toString();
login.Logino(new LoginDetails(email,password));

when debugging it will run this and go back to the button and after that it will give the exception and crash
public class LoginDetails {
public String email = "";
public String password = "";
LoginDetails(String e, String p) {
email = e;
password = p;

}
this is the code I'm trying to run with the button above
public void Logino(LoginDetails loginDetails) {
LoginTask task = new LoginTask();
task.execute(loginDetails);
}
From your StackTrace
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void uk.ac.abertay.contactslist.Login.Logino(uk.ac.abertay.contactslist.LoginDetails)
The line login.Logino the object login is null, you have to initialize it.
