Get Resource Id from ImageView

Get Resource Id from ImageView - android

I am trying to develop a little game.
I have a ViewFlipper which has 50 pictures (random frequence of 4 pictures) in ImageViews. Then I have 4 Buttons with the same 4 pictures which can appear in the ViewFlipper.
The task is to click the right button when the right picture appears.
(When Picture 1 appears Button 1 has to be pressed and so on)
My Problem is I don't know how to get the displayed ImageView id.
flipper.getCurrentView().getId()
gives me "-1" as Id. But I want to have the Id of "R.drawable.pic1"
My code so far:
my Loader-Method:
protected void loadPicturesIntoFlipper() {
Random generator = new Random();
pictures = new ArrayList();
for(int i = 0; i < 50;i++){
int number = generator.nextInt(4) + 1;
if(number == 1){
pic = R.drawable.pic1;
}
if(number == 2){
pic = R.drawable.pic2;
}
if(number == 3){
pic = R.drawable.pic3;
}
if(number == 4){
pic = R.drawable.pic4;
}
pictures.add(pic);
}
for(int i=0;i<pictures.size();i++)
{
setFlipperImage((Integer) pictures.get(i));
}
}
My Insert-Method:
private void setFlipperImage(int res) {
image = new ImageView(getApplicationContext());
image.setBackgroundResource(res);
flipper.addView(image);
}
My Check-Method :
protected void check(int number, int id) {
int code = 0;;
if(number == 1){
code = R.drawable.button_tip_finder;
}
if(number == 2){
code = R.drawable.button_about_us;
}
if(number == 3){
code = R.drawable.button_power_calculator;
}
if(number == 4){
code = R.drawable.button_powerpedia;
}
if(code == id){
test.setText(""+id);
}
else{
test.setText(""+id);
}
}
I call it like:
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
check(1,flipper.getCurrentView().getId());
flipper.showNext();
}
});

Do it like this:
private void setFlipperImage(int res) {
image = new ImageView(getContext());
image.setBackgroundResource(res);
image.setTag(res); //<------
flipper.addView(image);
}
and then:
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
check(1,(Integer)flipper.getCurrentView().getTag());//<----
flipper.showNext();
}
});
BTW use else in all of your code please, E.g:
if(number == 1){
pic = R.drawable.pic1;
} else if(number == 2){
pic = R.drawable.pic2;
} else if(number == 3){
pic = R.drawable.pic3;
}

may this one helps you,
int icon = getResources().getIdentifier([YOUR IMAGE NAME], "drawable",
getPackageName());

How to solve this scenario on Android Studio?

Click on red button 2 times and green button 3 times after this click on yellow button 5 times. If this done successfully you go on next screen for next quiz.

Assuming your buttons already connected to corresponding functions in Android Manifest
private int redClicks = 0;
private int greenClicks = 0;
private int yellowClicks = 0;
public void redClickCount(View view) {
if (redClicks < 2){
redClicks++;
}
greenClicks = 0;
yellowClicks = 0;
}
public void greenClickCount(View view) {
if (redClicks == 2 && greenClicks < 3){
greenClicks++;
} else { //start all over again
redClicks = 0;
greenClicks = 0;
yellowClicks = 0;
}
}
public void yellowClickCount(View view) {
if (redClicks == 2 && greenClicks == 3 && yellowClicks <5){
yellowClicks++;
} else {
if (redClicks == 2 && greenClicks == 3 && yellowClicks = 5){
// go to next round
} else {
//start all over again
redClicks = 0;
greenClicks = 0;
yellowClicks = 0;
}
}
}

How to calculate the values with using TextWatcher

I want to calculate totals of T,T2,T3,T4 which i given in calculate method.
how to calculate this values using TextWatcher
and if i don't put any value in calculate 3 () method. how can i store 0 value in T3.
for example
T= 2*3*1/144*2 = 0.08333
T2=2*3*1/144*2 = 0.08333
T3= if no any num of value put =0
T4=2*3*1/144*2 = 0.08333
fullTotal = 0.2499

Use a loop like so:
int count = adapter.getCount();
for (int i = 0; i < count; i++) {
adapter.remove(adapter.getItem(i));
}
I think that should work
XcutionX

this what i understood, what you are going to do is:
First of all the 'easy' button will be enabled and the rest of two will be disabled (I guess).
buttonEasy.setEnabled(true);
buttonMediun.setEnabled(false);
buttonHard.setEnabled(false);
then after the quiz with 'easy' level is finished, check the score if it has reached a certain value. If yes, then you will enable the 'Medium' button with the code:
buttonMedium.setEnabled(true);

My activity won't pause when dialog is shown

I have been working on application that displays a problem and 4 possible answers. Answer correctly, and the next problem appears. A wrong answer or letting the timer run out results in a popup that tells the correct answer and that you just lost a "life". Everything works well except that when the popup appears, the countdown timer continues and generates another popup. I can't find a way to get the activity to wait for the button on the dialog to be pressed before continuing to the next problem. I have read many questions/answers here and combed through many pages on the android developers site. Any help with this problem would be greatly appreciated.

You have a repetitive loop insisde a timer...
Let say, when your timer is is finished, it will call onFinish() and you are calling doWrong() in onFinish(). and doWrong() is calling doPopUp() which will open a Dialog again.(repetitively). To avoid, maintain some flags(like boolean or int) and based on the value of the flag, you decide whether to show PopUp Dialog when timer is finished or cancel the Timer when you are dismissing Diaog...

Check all the view's background in an if statement in Android?

I have many buttons(81) from the left and right part of my layout. All in all, I have 162 buttons. I put those buttons to Button[] and I handle it properly.

private Button[] btn_left = new Button[left_lung.length];
Whenever I click on the button, just like in mine sweeper game, many buttons are randomly opened. And when it is opened, I am changing its background into R.drawable.affected. The goal of the game is to open all the buttons in left and right. My question is this, how can I check if all of the buttons are set in R.drawable.affected? Because after that, I will execute a method that will congratulate the user. Thanks in advance.
EDIT:
for (int i = 0; i < btn_right.length; i++) {
final int a = i;
int counter_total_affected = 0;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 1) {
right_lung.add(a);
btn_right[a].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
} else if (counter == 2) {
for (int i = 0; i < 2; i++) {
int n = i;
right_lung.add(a + n);
}
try {
for (int i = 0; i < 2; i++) {
int n = i;
btn_right[a + n].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (counter == 3) {
right_lung.add(a);
btn_right[a].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
} else if (counter == 4) {
for (int i = 0; i < 25; i++) {
int n = i;
right_lung.add(a + n);
}
try {
for (int i = 0; i < 25; i++) {
int n = i;
btn_right[a + n].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (counter == ...) {
//statements...
} else if (counter_total_affected == (btn_left.length + btn_right.length)) {
//CONGRATULATORY METHOD
}
counter++;
}
}

Increment the counter each time you change background of button and compare its value with length of button array. if both are same that means, all button backgrounds are set.
Try this :
for (int i = 0; i < btn_right.length; i++) {
final int b = i;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if btn_right[i].getDrawable().getConstantState().equals
(getResources().getDrawable(R.drawable.affected).getConstantState()))
{
if(counter == btn_right.length){
//Congratulate user...
}
}else{
btn_right[b].setBackgroundResource(R.drawable.affected);
counter++;
}
}
}

U can set Tag:
for (int i = 0; i < btn_right.length; i++) {
final int b = i;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 1) {
right_affected.add(b);
btn_right[b].setBackgroundResource(R.drawable.affected);
btn_right[b].setTag('1');
} else {
//some stuff here...
}
}
}
after congratulate the user set its Tag to 0.
EDIT:
ArrayList<Integer> arrayofId =new ArrayList<Integer>();
#Override
public void onClick(View v) {
if (counter == 1) {
right_affected.add(b);
btn_right[b].setBackgroundResource(R.drawable.affected);
arrayofId.add(b);//need to convert int to Integer.
} else {
//some stuff here...
}
}
To congratulate:
for(int i=0;i<arrayofId.size();i++)
{
// you can get here id of effected buttons
}
