'How to add our own images via java code to the image view that change continuously?
How to add our own image via java code to the image view. I use ImageUri to set the Image to Image View.
ImageView carView = root.findViewById(R.id.carview);
if (car.registeredCarsArray.containsKey(logins)){
String[] carImage = car.registeredCarsArray.get(logins).getCarImageArray();
for (int i = 0; ; i++) {
try {
sleep (1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
carView.setImageURI(Uri.parse(carImage[i%4]));
}
}
here activity not starting.(because of infinite for-loop). So, I tried Thread instead of using this in oncreate() function.
new Thread(new Runnable() {
@Override
public void run() {
ImageView carView = root.findViewById(R.id.carview);
if (car.registeredCarsArray.containsKey(logins)){
String[] carImage = car.registeredCarsArray.get(logins).getCarImageArray();
for (int i = 0; ; i++) {
try {
sleep (1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
carView.setImageURI(Uri.parse(carImage[i%4]));
}
}
}
}).start();
then I got this error :(
