i declare int score = 100 in my 1st activity and use it to my 2nd activity, now the int score is declared as array in 2nd act. but its declared in local variable so how can i use it to my 3rd activity?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_level2);
ans1 = findViewById(R.id.ans1);
btn1 = findViewById(R.id.btn1);
Intent i = getIntent();
final int[] score2 = {i.getIntExtra("fscore", 0)};
scr1 = (TextView) findViewById(R.id.scr1);
scr1.setText(String.valueOf(score2[0]));
btn1.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View view)
{
String answer = ans1.getText().toString();
if (score2[0] == 0)
{
Toast.makeText(getApplication(),"You Lose!", Toast.LENGTH_SHORT).show();
gameover();
}
else
{
if (answer.equalsIgnoreCase("ANSWER2"))
{
Toast.makeText(getApplication(),"CORRECT!!", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(getApplication(),"Wrong Answer -10 Points", Toast.LENGTH_SHORT).show();
score2[0] = score2[0] - 10;
scr1.setText(String.valueOf(score2[0]));
}
}
}
});
}
public void gameover()
{
Intent intent = new Intent(this, gameover.class);
startActivity(intent);
}
}
If you want to pass score on game over then your funtion body should look like :
Intent intent = new Intent(this, gameover.class).putExtra("score",yourIntValue);
startActivity(intent);
In your second activity :
intent.getIntExtra("score", defValue); // store in a variable or add in an array
it will give you that int value you passed and you can either add it in your array or pass it to third activity using same method as above.
One thing I noticed that you got an int array because you tried making that variable final to use in inner functions right?
final int[] score2 = {i.getIntExtra("fscore", 0)};
Why don't you go for declaring a global scope variable with private access if you are using the same value multiple times.
private int score2;
assign it a value where you have written final int[ ] score2 = {i.getIntExtra("fscore", 0)};,
score2 = i.getIntExtra("fscore",0);
now use score2 wherever you want.There won't be a need of taking array here

Here is my situation:
I have an OnCreate code like the following:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bunz = Bunz.getInstance(); //getting instance of bunz
bunz.setBunz(50);
bunz.setMoney(0);
bunz.setIncrement(1);
Button upgradeButton = (Button) findViewById(R.id.upgradeButton);
upgradeButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view){
Intent startIntent = new Intent(getApplicationContext(), UpgradeMenu.class);
startActivity(startIntent);
}
});
moneyCount = (TextView) findViewById(R.id.moneyCount);
bunzCount = (TextView) findViewById(R.id.bunzCount);
ImageButton bun = (ImageButton) findViewById(R.id.bun);
}
Notice how in my OnCreate code, I do 2 things; first, I initialize all the values I need:
bunz.setBunz(50);
bunz.setMoney(0);
bunz.setIncrement(1);
and then I display these values on TextViews and set up some Buttons and intents:
Button upgradeButton = (Button) findViewById(R.id.upgradeButton);
upgradeButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view){
Intent startIntent = new Intent(getApplicationContext(), UpgradeMenu.class);
startActivity(startIntent);
}
});
moneyCount = (TextView) findViewById(R.id.moneyCount);
bunzCount = (TextView) findViewById(R.id.bunzCount);
ImageButton bun = (ImageButton) findViewById(R.id.bun);
I'm new to Android studio, and here is the problem I'm having. I want to use onResume() to update these values in the TextView (I update them in another activity) every time I go back to this activity. However, if I move all the code in onCreate into onResume, then every time I go back to this activity, the values will be set to 50,0, and 1. I understand I could use a boolean, so that onCreate() triggers the first time the app is launched, but onResume() doesn't trigger, and then onResume() triggers after that, and simply copy and paste the second half of the onCreate code into onResume(), but that seems inefficient, and isn't how Android studio is designed to work. Can I somehow initialize the values in another location?
I have a global Bunz class that looks like the following:
public class Bunz {
private int bunz;
private int money;
private int increment;
//singleton code
private static Bunz instance;
private Bunz(){
}
public static Bunz getInstance(){
if (instance == null){
instance = new Bunz();
}
return instance;
}
public int getBunz() {
return bunz;
}
public void setBunz(int num){
bunz = num;
}
public int getMoney(){
return money;
}
public void setMoney(int num){
money = num;
}
public int getIncrement(){
return increment;
}
public void setIncrement(int num){
increment = num;
}
}
so maybe I could initialize these values here somehow?
Thanks!
here's one thing you could alternatively do:
public static Bunz getInstance(){
if (instance == null){
instance = new Bunz();
instance.setBunz(50);
instance.setMoney(0);
}
return instance;
}
in your instance creation here, try setting the values you want here, instead of in onCreate of the app.
you could just be making the changes in the constructor as well.
While your code uses statics, which I believe is unnecessary. Statics are not your average goto solution, they come with a hefty price of an object not eligible for GC.
You can get the result from the second activity via onActivityResult method.
First, start second activity using startAtivityForResult() //This takes in a request code(Int), it can be whatever you set.
First activity
Intent intent = new Intent(this, SecondActivity.class);
startActivityForResult(intent , 100);
Second Activity
//Do you work in the second activity, generate new data
Intent returnIntent = new Intent();
returnIntent.putExtra("bunz", 100);
returnIntent.putExtra("money", 200);
returnIntent.putExtra("increment", 2);
setResult(Activity.RESULT_OK, returnIntent);
finish();
Capture Second Activity Result
This code is supposed to be written in your first activity.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 100) { //Remember the code we set in startActivityForResult? This is where we identify our work
if(resultCode == Activity.RESULT_OK){ //Code to check if data is passed
Int bunz =data.getIntExtra("bunz")
bunz.setBunz(bunz)
.....
}
}
}
I have a task to make a simple restaurant menu app in Android. So, the home page consist of Food button and Drink button. If Food button clicked, the food menu page will appear. If Drink button clicked, the drink menu page will appear.
MainActivity.java:
int x = 1;
public int value()
{
x = 1;
return x;
}
public void clickFood(View view)
{
value();
Intent intent = new Intent(MainActivity.this, MenuList.class);
startActivity(intent);
}
public int value2()
{
x = 2;
return x;
}
public void clickDrink(View view)
{
value2();
Intent intent = new Intent(MainActivity.this, MenuList.class);
startActivity(intent);
}
MenuList.java:
mainListView = (ListView) findViewById(R.id.mainListView );
int y = 1;
if(main.x == y)
{
// List of food
fooddrink = new String[]{"Fried Chicken", "Fried Rice"};
}
else
{
// List of drink
fooddrink = new String[]{"Ice Tea", "Ice Coffee"};
}
ArrayList<String> listFoodDrink = new ArrayList<String>();
listFoodDrink.addAll( Arrays.asList(fooddrink) );
listAdapter = new ArrayAdapter<String>(this, R.layout.menu_list_row, listFoodDrink);
mainListView.setAdapter( listAdapter );
The problem, the output of ListView is always display food menu, despite I click Drink button. I find that this is because x value in MainActivity.java doesn't return the value, so the int x value always = 1.
How am I doing wrong?
This is your problem:
MainActivity main = new MainActivity();
You create a new instance of MainActivity (not the one you've "come from") where x = 1.
Make x in MainActivity, for example, static like
static int x = 1;
and use it in MenuList.java as follows:
if(MainActivity.x == y)
{ ...
But!
That is NOT how you should go in Android taking into consideration its component's lifecycle (more on that). Once MainActivity has been destroyed by the system, x, as being static, is always = 1, unless another instance of MainActivity has changed it.
So, you may use several options, one of which would be to store x value somewhere, e.g. in SharedPreferences. Another one would be to pass the value within Intent's extra as per #VVJ's answer.
You have two activities MainActivity and MenuListActivity.In MainActivity there are two buttons Food and Restaurant. You have handle click event for each as follows:
foodButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, MenuList.class);
intent.putExtra("type",1);//pass 1 for food
startActivity(intent);
}
});
restaurantButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, MenuList.class);
intent.putExtra("type",2);//pass 2 for Restaurant
startActivity(intent);
}
});
Now in your MenuList activity you have to take value of key "type" and based on type value pass appropriate data source to adapter.You can do something like this(in onCreate of MenuList activity):
int type=getActivity().getIntent().getExtras().getInt("type");
i(type==1)
{
// List of food
fooddrink = new String[]{"Fried Chicken", "Fried Rice"};
}
else
{
// List of drink
fooddrink = new String[]{"Ice Tea", "Ice Coffee"};
}
ArrayList<String> listFoodDrink = new ArrayList<String>();
listFoodDrink.addAll( Arrays.asList(fooddrink) );
listAdapter = new ArrayAdapter<String>(this, R.layout.menu_list_row, listFoodDrink);
mainListView.setAdapter( listAdapter );
I'm trying to transfer two numerical inputs from one activity to another's UI but when I click the button to change intent it crashes.
I get the following in logcat: http://pastebin.com/zkWPcSNZ , which suggests a problem with the way I parsed the data to the editTexts in CalcResult.
My question is what is wrong with the way I'm trying to pass the data to the CalcResult editText.Is there an alternative method of acheiving this?
My two classes look like this for reference:
public class MainActivity extends Activity implements OnClickListener {
//variables for xml objects
EditText offsetLength,offsetDepth,ductDepth;
Button calculate;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//setting the variables to the xml id's and setting the click listener on the calc button
offsetLength = (EditText)findViewById(R.id.offLength);
offsetDepth = (EditText)findViewById(R.id.offDepth);
ductDepth = (EditText)findViewById(R.id.ductDepth);
calculate = (Button)findViewById(R.id.calc);
calculate.setOnClickListener(this);//don't cast the listener to OnClickListener
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
String getoffsetlength = offsetLength.getText().toString();
String getoffsetdepth = offsetDepth.getText().toString();
String getductdepth = ductDepth.getText().toString();
double tri1,tri2;
double marking1,marking2;
double off1 = Double.parseDouble(getoffsetlength);
double off2 = Double.parseDouble(getoffsetdepth);
double off3 = Double.parseDouble(getductdepth)
;
marking1 = Math.pow(off1,2) + Math.pow(off2,2);
tri1 = (float)off2/(float)off1;
tri2 = (float)off3/Math.atan((float)tri1);
marking2 = (float)off3/Math.atan(tri2);
Intent myIntent = new Intent(MainActivity.this, CalcResult.class);
myIntent.putExtra("numbers", marking1);
myIntent.putExtra("numbers", marking2);
startActivity(myIntent);
} catch (NumberFormatException e) {
// TODO: handle exception
System.out.println("Must enter a numeric value!");
}
}
}
This is the activity that I'm passing the data to:
public class CalcResult extends MainActivity
{
EditText result1,result2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.result);
result1 = (EditText)findViewById(R.id.mark1);
result2 = (EditText)findViewById(R.id.mark2);
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
double mark1 = bundle.getDouble("number1");
double mark2 = bundle.getDouble("number2");
int a = Integer.valueOf(result1.getText().toString());
int b = Integer.valueOf(result2.getText().toString());
result1.setText(a + " ");
result2.setText(b + " ");
}
}
When you start your second activity, both editText are empty
So when you do :
int a = Integer.valueOf(result1.getText().toString());
int b = Integer.valueOf(result2.getText().toString());
it's equivalent to :
int a = Integer.valueOf("");
int b = Integer.valueOf("");
which throws the exception
Caused by: java.lang.NumberFormatException: Invalid int: ""
If you want to set them the values you passed through both activities, you can just do :
double mark1 = bundle.getDouble("number1");
double mark2 = bundle.getDouble("number2");
result1.setText(mark1 + " ");
result2.setText(mark2 + " ");
The error is that you are putting your extras with same key "numbers" , and you are trying to retreive them by another keys "number1" and "number2". your code should be like this :
Intent myIntent = new Intent(MainActivity.this, CalcResult.class);
myIntent.putExtra("number1", marking1);
myIntent.putExtra("number2", marking2);
and to retreive them you should use :
Intent intent = getIntent();
double mark1 = intent.getDoubleExtra("number1", 0);
double mark2 = intent.getDoubleExtra("number2", 0);
And then , set the variables on your EditTexts like this :
result1 = (EditText)findViewById(R.id.mark1);
result2 = (EditText)findViewById(R.id.mark2);
result1.setText(mark1+"");
result2.setText(mark2+"");
you are using the same name for your extras when sending the intent, try correcting them.
This is kind of hard to explain. Basically it's kind of like a simple game. I want the people to input their names (currently the submit button is not working correctly) hit submit for each name and when all names are in they hit play. It then opens up the next class. It needs to get the string array from the prior class as well as the number of players. It then needs to select each persons name in order and give them a task to do (which it randomly generates). Then it allows the other people to click a button scoring how they did. (I am not sure how to set up the score system. Not sure if there is a way to assign a score number to a particular array string) I would then like it after 5 rounds to display the winner. If you have any input or could help me out I would be extremely grateful. Thanks for taking the time... here are the two classes i have.
Class 1
public class Class1 extends Activity
{
int players=0;
String names[];
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.class1);
final EditText input = (EditText) findViewById(R.id.nameinput);

submitButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View submit1)
{
players++;
for(int i=0; i < players; i++)
{
names[i] = input.getText().toString();
input.setText("");
}
}
});
Button doneButton = (Button) findViewById(R.id.done_btn);
doneButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View done1)
{
Intent done = new Intent(Class1.this, Class2.class);
done.putExtra("players", players);
done.putExtra("names", names[players]);
startActivity(done);
}
});
}
Class 2
public class Class2 extends Activity
{
int players, counter, score, ptasks,rindex;
String[] names, tasks;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.class2);
Intent game = getIntent();
players = game.getIntExtra("players", 1);
names = game.getStringArrayExtra("names");
Random generator = new Random();
tasks[0]= "task1";
tasks[1]= "task2";
tasks[2]= "task3";
tasks[3]= "task4";
tasks[4]= "task5";
tasks[5]= "task6";
tasks[6]= "task7";
tasks[7]= "task8";
tasks[8]= "task9";
tasks[9]= "task10";
while (counter <5)
{
for (int i = 0; i < players; i++)
{
TextView name1 = (TextView) findViewById(R.id.pname);
name1.setText( names[i]+":");
ptasks = 10;
rindex = generator.nextInt(ptasks);
TextView task = (TextView) findViewById(R.id.task);
task.setText( tasks[rindex]);
}
Button failButton = (Button) findViewById(R.id.fail_btn);
failButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View failed)
{
//not sure what to put here to get the scores set up
}
});
Button notButton = (Button) findViewById(R.id.notbad_btn);
notButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View notbad)
{
//not sure what to put here to get the scores set up
}
});
Button champButton = (Button) findViewById(R.id.champ_btn);
champButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View champp)
{
//not sure what to put here
}
});
counter++;
}
}
I'm sure this thing is riddled with errors. And I'm sorry if it is I'm not that well experienced a programmer. Thanks again
You can pass a string array from one activity to another using a Bundle.
Bundle bundle = new Bundle();
bundle.putStringArray("arrayKey", stringArray);
You can then access this stringArray from the next activity as follows:
Bundle bundle = this.getIntent().getExtras();
String[] stringArray = bundle.getStringArray("arrayKey");
I'm not sure if this is the only thing you intend to do. I hope it helps. Also, to assign a score to a particular string array, assuming your scores are int's you could use a HashMap as follows,
HashMap<String[],int> imageData = new HashMap<String[],int>();
But I'm not sure how you would pass this Map to another activity if you intend to do so.
http://developer.android.com/reference/android/content/Intent.html#putExtra(java.lang.String,%20java.lang.String[])
Use this cheat:
In Class2, convert you array string (tasks) to string (strSavedTask)by adding "|" separator. After that, pass your strSavedTask into Bundle and start to Class1.
When return to Class1, read strSavedTask from Bundle, split it by "|".
That's my cheat to pass array between 2 activity ^^
Hope this way can help you!
To all you that have helped me with my other questions thank you. I almost have it, but 2 final problems are preventing it from working the way i want.
These 2 classes are supposed to do as follows. 1st class gets the names of the people that want to play the game. Uses the same EditText and when they input their name they click submit. When all the names are submitted they click the done/play button which sends them and their data (how many players and names) to the next class. On class 1 i believe the error lies in the submit button. I'm trying to add all the names to an array list and I dont believe it is doing it correctly. When I run the app it takes in the names just fine from the users standpoint. But on the following screen it should display their name: (it says null so it is not getting the names correctly) and a task to do (which it does correctly).
The last thing it needs to do is on class 2 it needs to allow those buttons (failed, champ, and not bad) to only need to be clicked once (then it sets a score to the name of the person who's turn it was) and then it needs to start the next person and task. (It does neither atm). I would really appreciate help getting this blasted thing to work. Thanks to all who take the time to reply. And sorry if ur sick of seeing my help requests.

As a side note. The things that you see within those sections that have // comments next to them I have there because i was testing out between those and the ones that arent commented out and neither worked. If you have any input on fixing any of this i appreciate it.
I see two problems with your code that might explain why you get a null for your players list in your second Activity:
In Game, String[] names = bundle.getStringArray("arrayKey"); should be
ArrayList<String> names = bundle.getStringArrayList("arrayKey");`
In Class1, you're putting the ArrayList into the Bundle(bundle.putStringArrayList("arrayKey", names);) which is pointless since bundle goes no where. You should be putting it into the Intent instead:
done.putStringListExtra("arrayKey", names);
Note that your code is all the more confusing because you have both a String [] named names and an ArrayList named names in different scopes. Decide on one (I'd recommend the List) and get rid of the other.
Also, in Game, this is unncessary:
Bundle bundle = this.getIntent().getExtras();
String[] names = bundle.getStringArray("arrayKey");
Intent game = getIntent();
players = game.getIntExtra("players", 1);
You already have the bundle just before this, so you could as well do:
Bundle bundle = this.getIntent().getExtras();
String[] names = bundle.getStringArray("arrayKey");
players = bundle.getInt("players", 1);
The basic concept is that from the calling activity, you put information into an Intent using the various putExtra() and putExtraXXX() methods. In the called activity, you get the information you had put into the Intent by either
getting a Bundle *from * the Intent via getExtras() and then getting everything put in using the various get() methods on the Bundle (not the Intent).
directly invoking the getExtraXXX() methods on the Intent.
For the second part, as your code currently stands, it simply going to loop over all the players immediately (5 times in all, I don't understand the purpose of counter).
What you should instead be doing is performing all of your processing (calculating the score for the current player, incrementing the value of the player index, setting the next task etc) only when one of the 3 buttons is pressed. If it's going to be a long-lived task, you could disable the buttons until finished in order to enforce the requirement of allowing only one button to be pressed per player. Re-enable the buttons when the next player is ready.
I don't have the energy to churn out everything you need but at a starting point, turn this:
public void onCreate(Bundle savedInstanceState)
{
//...other code here

for (int i = 0; i < players; i++)
