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;
}
