I have a problem. I got a simple clicker here, but the "upgraded clicks per tap" are not transferred to the other activity. I don't know why it is not working.
Code as below :
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.content.Intent;
public class MainActivity extends AppCompatActivity {
public static final int REQUEST_CODE_CURRENTCLICKS = 10;
public int amountClicks = 0;
public int incrementAmount = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btnClick = (Button) findViewById(R.id.btnClick);
final TextView tvAmountClicks = (TextView) findViewById(R.id.tvAmoutClicks);
Button btnShop = (Button) findViewById(R.id.btnShop);
amountClicks = getIntent().getIntExtra("currentClicks", 0);
incrementAmount = getIntent().getIntExtra("upgradedClicks", 1);
tvAmountClicks.setText(""+amountClicks);
btnClick.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
amountClicks += incrementAmount;
tvAmountClicks.setText(""+amountClicks);
}
});
btnShop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(),ShopActivity.class);
intent.putExtra("currentClicks",amountClicks);
startActivityForResult(intent, REQUEST_CODE_CURRENTCLICKS);
}
});
}
}
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
public class ShopActivity extends AppCompatActivity {
public int currentClicks;
public int incrementAmount;
public int upgradedClicks;
public int upgradeCost = 10;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_shop);
currentClicks = getIntent().getIntExtra("currentClicks",0);
final TextView tvCurrentClicks = (TextView) findViewById(R.id.tvCurrentClicks);
tvCurrentClicks.setText(""+currentClicks);
Button btnUpgrade = (Button) findViewById(R.id.btnUpgrade);
btnUpgrade.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(upgradeCost > currentClicks)
{
Context context = getApplicationContext();
CharSequence text = "You don't have enough Clicks";
int duration = Toast.LENGTH_SHORT;
Toast cantUpgrade = Toast.makeText(context, text,duration);
cantUpgrade.show();
}
else
{
currentClicks -= upgradeCost;
upgradedClicks++;
tvCurrentClicks.setText(""+ currentClicks);
}
Intent intent = new Intent();
intent.putExtra("currentClicks",currentClicks);
intent.putExtra("upgradedClicks",upgradedClicks);
setResult(RESULT_OK, intent);
}
});
}
}
If I return back to the main activity, it doesnt return the "upgraded clicks" nor the "current clicks".
You have startActivityForResult therefore you need to implement onActivityResult
So, you have this code
Intent intent = new Intent();
intent.putExtra("currentClicks",currentClicks);
intent.putExtra("upgradedClicks",upgradedClicks);
setResult(RESULT_OK, intent);
finish(); // Add finish() to end this Activity
And that would go back to the calling Activity where you check the request code.
public class MainActivity extends AppCompatActivity {
public static final int REQUEST_CODE_CURRENTCLICKS = 10;
public int amountClicks = 0;
private TextView tvAmountClicks;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == REQUEST_CODE_CURRENTCLICKS) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
amountClicks = data.getIntExtra("currentClicks", 0);
int upgradedClicks = data.getIntExtra("upgradedClicks", 1);
tvAmountClicks.setText(""+amountClicks);
}
}
}
Android | Getting the result of an Activity
You should override the MainActivity's onResume() method to refresh your data.
EDIT try this one
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
if(resultCode == RESULT_OK){
amountClicks = getIntent().getIntExtra("currentClicks", 0);
incrementAmount = getIntent().getIntExtra("upgradedClicks", 1);
tvAmountClicks.setText(""+amountClicks);
}
}
}

I found that my function of the app is not working for certain android phone.
I think maybe is the problem of android version? My app is working fine on an other Android phone, so how can I solve this issue?
public class StartActivity extends AppCompatActivity {
private Button btnupload,btnchoose;
private ImageView imgprofile;
Uri filepath;
private static final int PICK_IMAGE_REQUEST = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_start);
btnchoose = (Button)findViewById(R.id.btn_addphoto);
btnupload = (Button)findViewById(R.id.btn_upload);
imgprofile = (ImageView)findViewById(R.id.imageView);
btnchoose.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
chooseimage();
}
});
btnupload.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
}
private void chooseimage() {
Intent intent = new Intent();
// Show only images, no videos or anything else
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
// Always show the chooser (if there are multiple options available)
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK) {
filepath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(),filepath);
if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1) {
Toast.makeText(StartActivity.this, "YES!", Toast.LENGTH_SHORT).show();
bitmap = Bitmap.createScaledBitmap(bitmap, imgprofile.getWidth(),imgprofile.getHeight(),true);
imgprofile.setImageBitmap(bitmap);
} else {
Toast.makeText(StartActivity.this, "YES!!!!", Toast.LENGTH_SHORT).show();
imgprofile.setImageBitmap(bitmap);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
I run my app on the phone which is version 5.0.2 it does not show any response of toast.
This is the code works for me. I just change the position of the function, the code still the same.

i was making an android app and i need to use one integer value in 2 activities. I tried using this code but it didn't work.
//Integer Sender
Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("MyIntNameGoesHere", intValue);
startActivity(myIntent);
//Integer receiver
Intent mIntent = getIntent();
int intValue = mIntent.getIntExtra("intVariableName", 0);
It says Cannot resolve symbol intValue and Cannot resolve symbol A and the same for B.
Here's the whole code.

ALL ABOVE IS ANSWERED! ---------------------------------------------------------
Now i have problems with this part of the code:
#Override
public void onClick(View v) {
if(balance >= 300){
balance -= 300;
}
if(balance < 300){
final TextView text = (TextView) findViewById(R.id.not_enough_money_text);
assert text != null;
text.setText("You do not have enough money.");
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
text.setText("");
}
}, 2000);
}
}
When i click the button it says i do not have enough money but i have over 300. Please help me.
I found out what the problem was but I'm not sure how to fix it. I need to send balance back to MainActivity. Can anyone help with that?
Send the data like this -
UpgradesButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, UpgradesActivity.class);
intent.putExtra("key_int", balance);
startActivity(intent);
}
});
And fetch it in onCreate() of UpgradesActivity -
Intent mIntent = getIntent();
int intValue = mIntent.getIntExtra("key_int", 0);
You're using different key when sending and receiving the Int.
Change this line:
int intValue = mIntent.getIntExtra("intVariableName", 0);
To this:
int intValue = mIntent.getIntExtra("MyIntNameGoesHere", 0);
I started a activity to grab contacts from a list of all the contacts on the phone. Now my issue is how do I return the selected checks correctly from the listview, directly into my Person class. Im not fully understanding the concept of Intents and Activities in general so please bear with me.
Here is how I start the Activity from MainActivity.java
static final int PICK_CONTACT_REQUEST = 1;
public void grabthecontacts(View view) {
Intent intent = new Intent(getApplicationContext(), SelectContactsActivity.class);
startActivityForResult(intent, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == Activity.RESULT_OK){
String result=data.getStringExtra("result");
}
if (resultCode == Activity.RESULT_CANCELED) {
}
}
}
Here is the class it calls, Select Contacts Activity

Person human = new Person(allcontacts.getName(), allcontacts.getPhone());
}
}
// How do I return human with this activity? or is there another method?
finish();
}
}
Im completely lost on how to return the values I want as a person, so I can simply do
hashsetname.add(human)
Any help even with general formatting is greatly appreciated, or any java tips too. Thank you
Try this,
First make Person class to Serializable,using
public class Person implements Serializable
now set ivalue in intent like this,
Intent returnIntent = new Intent();
returnIntent.putExtra("result", human);
setResult(Activity.RESULT_OK, returnIntent);
finish();
get value from intent in onActivityResult method,
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == Activity.RESULT_OK){
Person myObject = (Person) data.getParcelableExtra("result");
}
if (resultCode == Activity.RESULT_CANCELED) {
}
}
}
Intent i= new Intent();
i.putExtra("whatever",yourResult);
setResult(Activity.RESULT_OK, i);
finish();
add these two lines before calling finish();
Intent returnIntent = new Intent();
setResult(Activity.RESULT_OK, returnIntent);
finish();
So using suggestions from the last question I asked, I figured out how to call BarCodeScanner, and return the value to a field. so now, I have a toast that says "successful scan" and then I want to pass the result to a new activity. when I comment out my intent, everything works (minus the passing of data/switching of screen, obviously) but when I run my project as is, it FC's... no errors reported by eclipse in code or XML. Any insights?
package com.mhe.test.scan;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class main extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button myScanButton = (Button) findViewById(R.id.myScanButton);
totalbox = (EditText) findViewById(R.id.tBox);
myScanButton.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
startActivityForResult(intent, 0);
}
});
}
private EditText totalbox;
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
final String contents = intent.getStringExtra("SCAN_RESULT");
if ( totalbox != null )
totalbox.setText(contents);
Context context = getApplicationContext();
CharSequence text = "Successful Scan";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
Intent i = new Intent(main.this, Result.class);
i.putExtra("SNARP", "SCAN_RESULT");
startActivityForResult(i, 0);
} else if (resultCode == RESULT_CANCELED) {
if ( totalbox != null )
totalbox.setText("bummer");
}
}
}
}
And then to handle the data being passed, in the new activity:
package com.mhe.test.scan;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

Try sending a Bundle object when calling the new intent.
Intent i = new Intent(main.this, Result.class);
Bundle b = new Bundle();
b.putString("SNARP", "SCAN_RESULT")
i.putExtras(b);
Try getting string in the child Activity this way.
