Android Studio: Activity only finishes when you call the finish() for second time

So, we're working with intents at school and I'm having trouble with the intents when I try to pass data from the "Activity2" to the "Activity1", when I do the setResult() and stuff. The problem is it won't go back to the first activity when I trigger the event the first time, but it will the second.
I've been working with Android studio only for about 12h so I really lack a lot of understanding.
Here is what I'm doing:
First I call this form the main activity.
public void CheckPassword(View view) {
password = PasswordManagement.getPassword(this);
TextView txtPassword = findViewById(R.id.txtPassword);
if (txtPassword.getText().toString().equals(password)) {
Intent intent;
intent = new Intent(this, WelcomeActivity.class);
intent.putExtra("password", password);
startActivityForResult(intent, 1);
startActivity(intent);
} else {
Intent intent;
intent = new Intent(this, RestrictedActivity.class);
startActivityForResult(intent, 1);
startActivity(intent);
}
}
Then, when I'm done from the second activity I run this:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_restricted);
lblRestrictedArea = findViewById(R.id.lblRestrictedArea);
lblRestrictedArea.setOnLongClickListener(
new OnLongClickListener() {
public boolean onLongClick(View view) {
intent = new Intent();
intent.putExtra(EXTRA_RESPONSE, true);
setResult(RESULT_OK, intent);
finish();
return false;
}
});
}
And back to the main activity I overwrote this to act according to the response:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
if (data.getBooleanExtra(RestrictedActivity.EXTRA_RESPONSE,false)){
LinearLayoutPasswordActivity.setBackgroundColor(getResources().getColor(R.color.red));
}else{
LinearLayoutPasswordActivity.setBackgroundColor(getResources().getColor(R.color.white));
}
}
}
}
If anyone can help I would be very glad, meanwhile I'll try to solve it my own.
Thanks!

Your are calling startActivity twice. So there are two instance of the same Activity and then you have to finish twice.
Keep your startActivityForResult(...) and delete startActivity in CheckPassword(View view)
->
public void CheckPassword(View view) {
password = PasswordManagement.getPassword(this);
TextView txtPassword = findViewById(R.id.txtPassword);
if (txtPassword.getText().toString().equals(password)) {
Intent intent;
intent = new Intent(this, WelcomeActivity.class);
intent.putExtra("password", password);
startActivityForResult(intent, 1);
// startActivity(intent);
} else {
Intent intent;
intent = new Intent(this, RestrictedActivity.class);
startActivityForResult(intent, 1);
//startActivity(intent);
}
}
Plus, note that you are using the same requestCode (1) for two different activities. The requestCode is very important for onActivityResult method.

Passing a string or a variable from a dialoguebox to an activity Android

I wan to implicitly pass two string or variable from a dialoguebox to be used by another activity and at the same time opening that activity.
dialoguebox
String city = addresses.get(0).getLocality();
String category = "Hazard";
AlertDialog.Builder prompt = new
AlertDialog.Builder(MapsActivity.this);
prompt.setCancelable(false)
.setPositiveButton("Mineralization", new
DialogInterface.OnClickListener() {
.setPositivetiveButton("Geohazard", new
DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,
int which) {
startActivity(new
Intent(getApplicationContext(),MapsActivity.class));
//i want to pass the String city and category here
}
}
)
AlertDialog alert = prompt.create();
alert.setTitle("Please select an option");
alert.show();
TextView myTextView = (TextView) findViewById(R.id.PSString);
myTextView.setText(city);
New activity
package com.example.boneyflesh.homepage;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class GeohazardResults extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_geohazard_results);
}
}
how do i do this? what do i write on the onClickListener and what do i do on the new activity so that i can get the strings?

Instead of doing something like this in your onClick method
startActivity(new Intent(getApplicationContext(),MapsActivity.class));
You can just pass the two strings through the intent to the MapsActivity inside your onClick method as shown below
Intent lIntent = new Intent(getApplicationContext(), MapsActivity.class);
lIntent.putExtra("city", city);
lIntent.putExtra("category", category);
startActivity(lIntent);
and retrieve those values in MapsActivity as shown below
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_geohazard_results);
String city = getIntent().getStringExtra("city");
String category = getIntent().getStringExtra("category");
}

Pass Using Intent and Bundle like Below:
Intent intent = new Intent(getApplicationContext(),MapsActivity.class));
Bundle bundle =new Bundle();
bundle.putString("key1","value1");
bundle.putString("key2","value2");
intent.putExtras(bundle);
startActivity(intent );
And Retrieve value in next Activity like below:
Bundle bundle = getIntent().getExtras();
String value1= bundle.getString("key1");
String value2= bundle.getString("key2");

You need to use extras to send the data.
For example:
Intent intent = new Intent(getApplicationContext(),MapsActivity.class);
intent.putExtra("SOME_NAME_HERE", theString);
startActivity(intent);
Then, in the target activity you write - in onCreate:
Bundle extras = getIntent().getExtras();
if(extras == null) {
theString= null;
} else {
theString = extras.getString("SOME_NAME_HERE");
}

In your dialogbox:
Intent i = new Intent(MapsActivity.this, GeohazardResults.class);
i.putExtra("city", city);
i.putExtra("category", categoty);
startActivity(i);
In your new activity:
Intent i = getIntent();
Bundle extras = i.getExtras();
String city = extras.getString("city");
String category = extras.getString("category");

Instead of doing this -:
startActivity(new Intent(getApplicationContext(),MapsActivity.class));
Do something like this -:
Intent mapsActivityIntent = new Intent(getApplicationContext(), MapsActivity.class);
mapsActivityIntent.putExtra("CITY", city);
mapsActivityIntent.putExtra("CATEGORY", category);
startActivity(mapsActivityIntent);
In your activity you can then get them by doing :
getIntent().getStringExtra("CITY");
getIntent().getStringExtra("CATEGORY");

DialogInterface.OnClickListener() {
.setPositivetiveButton("Geohazard", new
DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog,
int which) {
Intent intent = new Intent(getApplicationContext(),MapsActivity.class))
// intent.putExtra(key,value);
intent.putExtra("String1","value1");
intent.putExtra("String2","value2");
startActitvity(intent);
}
}
)
in Acivity
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if(extras != null){
//intent.getStringExtra(key)
string1 = intent.getStringExtra("String1");
string2 = intent.getStringExtra("String2");
}
i would suggest define keys as constants and use those while passing values, to avoid any confusion

pass intent from your dialog like this
Intent intent=new Intent(context, GeohazardResults.class);
Bundle parameters=new Bundle();
parameters.putString("city",city);
parameters.putString("category",category);
intent.putExtra("key",parameters);
startActivity(intent);
and in the next activity receive thiese values like this.
Intent receivedIntent=getIntent();
if(receivedIntent!=null){
Bundle parameters=receivedIntent.getBundleExtra("key");
if(parameters!=null){
String city=parameters.getString("city");
String category=parameters.getString("category");
}
}

How intent object keep/transfer data between two Activity in android?

i have these two Activity and each in the separate file:
public class MainActivity extends AppCompatActivity {
public final static String EXTRA_MESSAGE = "com.example.myfirstapp.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
/** Called when the user clicks the Send button */
public void sendMessage(View view) {
Intent intent = new Intent(this, DisplayMessageActivity.class);
EditText editText = (EditText) findViewById(R.id.edit_message);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}
public class DisplayMessageActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_message);
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
TextView textView = new TextView(this);
textView.setTextSize(40);
textView.setText(message);
ViewGroup layout = (ViewGroup) findViewById(R.id.activity_display_message);
layout.addView(textView);
}
}
in MainActivity we create Intent object and hold him some data ,
in the DisplayMessageActivity we get this intent using getIntent() method ,
and this method return to us Intent object
my question is how this method return to us the same Intent that we create in MainActivity ??

According to official documentation, get intent is used to
Return the intent that started this activity.
It means it is a function that returns the intent that originally started that activity.
That answers your query.
Android Developers Documentation - Activity - getIntent()
It is always a good practice to read official documentation.
The general syntax to add extras is:
Intent intent = new Intent(context, activity.class); //Create intent to start activity
intent.putExtra("key", data); //adding data
startActivity(intent);
To receive that data, from the Activity you started:
Intent intent = getIntent();
String data = intent.getExtra("key");
The String variable - data will hold the value that you attached with the previous activity. This means, you can only use this method till the next activity.

You have to implement onActivityResult in you MainActivity and start DisplayMessageActivity with startActivityForResult:
... sendMessage(View view) {
...
startActivityForResult(intent, MESSAGE_RESULT_CODE);
}
public void onActivityResult(int requestcode, int resultcode, Intent data) {
//You can get your result intent data here
if (requestcode == MESSAGE_RESULT_CODE && resultcode == RESULT_OK) {
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
}
}
and just add in DisplayMessageActivity in onPause, onStop or onBackPressed and onSupportNavigateUp:
//in your case maybe 'your_intent_sent_back_to_mainactivity = getIntent();'
setResult(RESULT_OK, your_intent_sent_back_to_mainactivity);

How to call one activity multiple times based on from which the activity has been called?

I have one activity which is common for all other activities. I want to call this activity and want to set some conditions based on from which activity it has been called. I thought of bundle for this. How can I call a condition based on bundle value? I have another activity in between. I am not calling the activity directly. So how can we pass data by using bundle?
txt_from.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
i = new Intent(getApplicationContext(), PickLocationActivity.class);
GoSendData.instance.addressType = 0;
i.putExtra("type",1);
startActivity(i);
}
});
From this I am calling second activity.
In common activity I have a view I am calling the activity back from this. The activity from which it has been called , it should be called back from this view.
useLocation.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Bundle extras = intent.getExtras();
activityType = extras.getInt("type");
if(activityType==0) {
intent = new Intent(ChooseFromMapActivity.this, GoSend.class);
startActivity(intent);
}
if(activityType == 1)
{
intent = new Intent(ChooseFromMapActivity.this, GoRideActivity.class);
startActivity(intent);
}
}
});
How to achieve this...?
How can I do this with shared preferences?

Change
Bundle extras = intent.getExtras();
to
Bundle extras = getIntent().getExtras();
Hope this helps :)

Check the below code
Activity_1. : This will send the data to the Common Activity.
Intent i = new Intent(Activity_1.this, CommonActivity.class);
i.putExtra("type",1);
startActivity(i);
Activity_2. : This will send the data to the Common Activity.
Intent i = new Intent(Activity_2.this, CommonActivity.class);
i.putExtra("type",2);
startActivity(i);
Then on your Common Activity write this code in the onCreate function.
int receivedValue = getIntent().getIntExtra("type", 0);
// here 0 is the default value when there is no data in the particular key.
now you can check the condition like this
if(receivedValue==1)
{
// do something here
}
if(receivedValue==2)
{
// do something here
}
This will definitely work for you. Try it..!!
Happy coding.

Activity1,
txt_from.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
i = new Intent(getApplicationContext(), PickLocationActivity.class);
GoSendData.instance.addressType = 0;
i.putExtra("type",1);
startActivity(i);
}
});
Activity2,
txt_from.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
i = new Intent(getApplicationContext(), PickLocationActivity.class);
GoSendData.instance.addressType = 0;
i.putExtra("type",2);
startActivity(i);
}
});
Common Activity
useLocation.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = getIntent();
int type = i.getInt("type");
if(type==1) {
Intent intent = new Intent(ChooseFromMapActivity.this, Activity1.class);
startActivity(intent);
}
if(type == 2)
{
Intent intent = new Intent(ChooseFromMapActivity.this, Activity2.class);
startActivity(intent);
}
}
});

How Create intent for an activityTwo

Im new on Java so its confusing me a little bit, i want to create an intent for Activity two but there seem to be a problem with the code that i have written.
#Override
public void onClick(View v) {
// TODO:
// Launch Activity Two
// Hint: use Context's startActivity() method
// Create an intent stating which Activity you would like to
// start
Intent activityTwo = new Intent(ActivityTwo.this.finish());
Intent intent = null;
// Launch the Activity using the intent
startActivity(activityTwo);
}
});
// Has previous state been saved?
if (savedInstanceState != null) {
// TODO:
// Restore value of counters from saved state
super.onRestoreInstanceState(savedInstanceState);
mCreate = savedInstanceState.getInt(CREATE_KEY);
mRestart = savedInstanceState.getInt(RESTART_KEY);
mStart = savedInstanceState.getInt(START_KEY);
}
// Emit LogCat message
Log.i(TAG, "Entered the onCreate() method");
// TODO:

from First to Second:
Button next = (Button) findViewById(R.id.button2);
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent intent = new Intent(getApplicationContext(),Second.class);
intent.putExtra("Tag", "Value");
startActivity(intent);
finish();
}});
Second to First:
Button previous= (Button) findViewById(R.id.button);
previous.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent intent = new Intent(getApplicationContext(),First.class);
startActivity(intent);
}});

First Understand the concept of Intent.
In your case, you want to call ActivityTwo from ActivityOne.
follow this steps
Create ActivityTwo.
Declare ActivityTwo in your AndroidManifest.xml
<activity android:name=".ActivityTwo" />
Write Intent code where in onclick() method.
Intent intent = new Intent(getApplicationContext(),ActivityTwo.class);
startActivity(intent);
In this code Intent Constructor contains two parameters.
Current Context
ActivityTwo reference.
