I have 36 imageButtons and with each one I call the same popup in which I set random question from sqlite database. When user answers question by clicking one of the 4 possible solutions it closes and goes back to my 36 buttons. Now here I have 2 problems:
I use this code to avoid repeating questions. In activity scope:
LinkedList mAnsweredQuestions = new LinkedList();
private String generateWhereClause(){
StringBuilder result = new StringBuilder();
for (Long l : mAnsweredQuestions){
result.append(" AND _ID <> " + l);
}
return result.toString();
}
and in my question method:
mAnsweredQuestions.add(c.getLong(0));
But this does not work when my activity resumes after popup question close. It's like it loads my activity from scratch. I use this in my other game and it works fine in "normal" activity, but for some reason after popup it does not.
2.I need for each imageButton press to launch this popup activity and after each correct answer to save different number of points. I used startActivityForResult in my other game to start activity and save result, but in that case I was starting different activities with each button. Now I have to start the same activity, and save back different results. How can I do that?
Here's my popup question class:
public class Pitanja_Cigle extends Activity{
public static String tacanOdg;
int counter = 0;
Button b1, b2, b3, b4;
TextView question;
LinkedList<Long> mAnsweredQuestions = new LinkedList<Long>();

StringBuilder result = new StringBuilder();
for (Long l : mAnsweredQuestions){
result.append(" AND _ID <> " + l);
}
return result.toString();
}

Is there any reason why method CreatePlan won't allow me access to variable recipe_name from the onRecipeClicked function which is retrieved from the recyclerview adapter. The Log shows that the value is retrieved from the recyclerview, but I can't seem to pass it to another method.
Any help is appreciated.
Update
Also is there a way of assigning the auto incremented id created from createPlanRecipe to the id variable in createPlan?

I want to make a function in which if a button on a different activity is pressed, then another function which is outside of this one will be invoked. But in case that the button is not pressed the function must not take place.
Here I leave you the code of what I've done so far(java.file:
public class Comida2 extends AppCompatActivity implements Adaptador2.OnRecipeListener {
private RecyclerView recyclerView1;
List<Entidad2> listItems;
Adaptador2 adaptor;
private Entidad2 entidad1,entidad2,entidad3;
Button cambiarmenu;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_comida);
cambiarmenu = (Button) findViewById(R.id.boton_cambiarmenu);
recyclerView1 = findViewById(R.id.lv_1);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView1.setLayoutManager(layoutManager);
listItems = new ArrayList<>();
entidad1 = new Entidad2(R.drawable.calabacines_3, "Solomillo a la plancha", " 10 min.", 4, 20);
entidad2 = new Entidad2(R.drawable.patatas_deluxe_especiadas_70523_300_150, "Entrecot", " 15 min.", 2, 50);
entidad3 = new Entidad2(R.drawable.tomate, "Hamburguesa", " 2 min.", 5, 100);
listItems.add(entidad1);
listItems.add(entidad2);
listItems.add(entidad3);
adaptor = new Adaptador2(listItems, this);
recyclerView1.setAdapter(adaptor);
adaptor.notifyDataSetChanged();
//Clicado();
}
#Override
public void OnRecipe(int priority) {
if (priority == 20) {
Intent in = new Intent(this, Solomillo.class);
startActivity(in);
}
if (priority == 50) {
Intent in = new Intent(this, Entrecot.class);
startActivity(in);
}
if (priority == 100) {
Intent in = new Intent(this, Hamburguesa.class);
startActivity(in);
}
}
private void Clicado(){
final boolean[] numerillo = new boolean[1];
cambiarmenu.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
numerillo[0] = true;
}
});
if (numerillo[0]) {
pickEntidad();
}
}
private void pickEntidad(){
final int random = new Random().nextInt(101);
int priority1 = entidad1.getPriority();
int priority2 = entidad2.getPriority();
int priority3 = entidad3.getPriority();
listItems.clear();
if(random < priority1){
listItems.add(entidad1);
}else if(random < priority2){
listItems.add(entidad2);
}else if (random <= priority3){
listItems.add(entidad3);
}
adaptor.notifyDataSetChanged();
}
}
I want that if the button cambiarmenu is pressed, then the function pickEntidad is invoked, but that if its not, then nothing happens. I've had the problem that I had put the method in which if the button is pressed... inside the Oncreate, and then when it was not pressed the app crashed.
The method Clicado is not coded correctly as it is the method I tried to do myself in which I've included the if and the onClickListener.
Any idea of how to do it please?
Thanks.
I did see your another post and now I understand your problem.
"The button called cambaiarmenu is in another activity, not in Comida2" - what you said here Why can't I use a button which is not in the same activity as the java.file?
The moment you called
setContentView(R.layout.activity_comida);
you can only declare all widgets(button ,textview, etc) under that layout and which I believe R.id.boton_cambiarmenu(cambiarmenu button id) does not belong on that layout.
So you need to declare your cambiarmenu button on the activity where you declare its layout and call this inside its onclicklistener
new Comida2().pickEntidad(); //calling function pickEntidad from Comida2 class
Try this. change your pickEntidad like this
private void pickEntidad(){
final int random = new Random().nextInt(101);
List<Entidad2> newlistItems = new ArrayList<>();
Entidad2 entidad1 = new Entidad2(R.drawable.calabacines_3, "Solomillo a la plancha", " 10 min.", 4, 20);
Entidad2 entidad2 = new Entidad2(R.drawable.patatas_deluxe_especiadas_70523_300_150, "Entrecot", " 15 min.", 2, 50);
Entidad2 entidad3 = new Entidad2(R.drawable.tomate, "Hamburguesa", " 2 min.", 5, 100);
int priority1 = entidad1.getPriority();
int priority2 = entidad2.getPriority();
int priority3 = entidad3.getPriority();
if(random < priority1){
newlistItems.add(entidad1);
}else if(random < priority2){
newlistItems.add(entidad2);
}else if (random <= priority3){
newlistItems.add(entidad3);
}
adaptor.notifyDataSetChanged(); //this another activity listview adaptor so it useless to notify it when you are not this activity
}
I'm currently working on developing an Android app, in which I have an Activity where the user can see all of their current streaks (which were created programmatically with data accessed from Android's SQLite database).
I'm trying to then pass this data when clicked into another activity which displays an individual streak from the list of all streaks. I would need to pass all 4 pieces of information (streak name, streak category, date started, and days kept), and I'm honestly not quite sure where to start. Below is what I have so far, and while I'm not getting errors - this is currently passing either null, 0 or simply nothing to EnlargedActivity.java.
I currently have most of my code in EnlargedActivity's onResume() method, since whenever a new button is clicked, new data has to be passed in - although I'm not sure if that's the best way to do this, I'm still pretty new to Android programming. Thanks!

I made an app for my use for calculating a string of values appear in an another activity. My app has 3 editTexts and one button. If we press button calculate with the input in edit text and calculated values will displayed in a second activity. I made it successfully but my problem is if the user is leave any of the boxes empty and press the button, the system will Force Close. To avoid this I made editText in graphical layout pre entered with a hint. But if the user accidentally presses button after editing the editText again system shows a Force Close.
I tried many if else methods but it does not work. Some one show me a correct way to check all editText boxes.
public class Screen1 extends Activity {
public static StringBuilder EXTRA_MESSAGE=null;
#Override

{
#Override

String vis;
EditText t1=(EditText)findViewById(R.id.a);

String e1=t1.getText().toString();
String e3= t3.getText().toString();
String e4= t4.getText().toString();

f3=Integer.parseInt(e3);

for( float i= (float)0.1;i<=5;i=i+(float) .1)

Using [TextUtils][1] check isEmpty() text inside your onClick:
#Override
public void onCreate(Bundle savedInstanceState){
EditText t1=(EditText)findViewById(R.id.a);
EditText t3=(EditText)findViewById(R.id.c);
EditText t4=(EditText)findViewById(R.id.d);
Button bu1 = (Button) findViewById(R.id.bu);
bu1.setOnClickListener(this);
}
#Override
public void onClick(View message){
boolean foundEmpty = false;
if(TextUtils.isEmpty(t1.getText())) {
foundEmpty = true;
t1.setError("Please Enter a value");
}
if(TextUtils.isEmpty(t2.getText()){
foundEmpty = true;
t2.setError("Please Enter a value");
}
if(TextUtils.isEmpty(t3.getText()){
foundEmpty = true;
t3.setError("Please enter a value");
}
if(!foundEmpty){
/* none of your text fields are empty */
int f1, f3, f4;
f1 =Integer.parseInt(e1);
f4=Integer.parseInt(e4);
f3=Integer.parseInt(e3);
final StringBuilder sb = new StringBuilder();
for( float i= (float)0.1;i<=5;i=i+(float) .1) {
sb.append(String.format("%.1f", i)+
" mcg = "+
(f1*60*i*f4)/(f3*1000)+"\n");
}
final String vis = sb.toString();
Intent intent = new Intent(message.getContext(), Screen2.class);
intent.putExtra("EXTRA_MESSAGE", vis);
startActivity(intent);
}
}
From what I gather from your question, you're getting an error when bu1 is clicked, and at least one of the EditTexts is empty. This is because you're calling Integer.parseInt() on an empty String. The following code will check if the boxes are empty, and show a Toast if any are. It will also show a Toast if the user enters anything that's not a valid number:
public class Screen1 extends Activity
{
private static final String EXTRA_MESSAGE = "extra_msg";
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.screen1);
final EditText t1 = (EditText)findViewById(R.id.a);
final EditText t3 = (EditText)findViewById(R.id.c);
final EditText t4 = (EditText)findViewById(R.id.d);
Button bu1 = (Button)findViewById(R.id.bu);
bu1.setOnClickListener(new View.OnClickListener()
{
public void onClick(View message)
{
int f1,f3,f4;
String e1 = t1.getText().toString();
String e3 = t3.getText().toString();
String e4 = t4.getText().toString();
if (e1.equals("") || e3.equals("") || e4.equals(""))
{
Toast.makeText(Screen1.this, "Please enter all numbers.", Toast.LENGTH_SHORT).show();
return;
}
try
{
f1 = Integer.parseInt(e1);
f4 = Integer.parseInt(e4);
f3 = Integer.parseInt(e3);
StringBuilder sb = new StringBuilder();
for (float i = 0.1f; i <= 5; i = i + .1f)
{
sb.append(String.format("%.1f", i) + " mcg = " + (f1 * 60 * i * f4) / (f3 * 1000) + "\n");
}
Intent intent = new Intent(Screen1.this, Screen2.class);
intent.putExtra(EXTRA_MESSAGE, sb.toString());
startActivity(intent);
}
catch (NumberFormatException e)
{
Toast.makeText(Screen1.this, "Invalid numbers.", Toast.LENGTH_SHORT).show();
}
}
}
);
}
}
Like in "Who wants to be a millionaire". When a user press a 50/50 help button I want two wrong answers to hide, therefor to setText to "" for two buttons, BUT not "the answer" one.

OK, as jazzbassrob pointed I need to be more specific. I need to setText to my bPolaPola button to "", empty String, but my main problem is that I don't know after collections shuffle where my answers will end up, so I don't know which buttons to setText to. How to know where my answers end up after shuffle?
I actually did not try anything cause in this specific situation I really don't know where to start.
How about running a query which will find the correct option even before the user clicks on one, then you find the correct button out of the four options. After this, use setText="" on any random two buttons other than the one which points to the correct answer.
