How To Change The Image Of A Button

My problem here is how to display a new image for button after it was clicked but the condition is from the other class. Im a newbie here and I want to know how to connect the clas

Solution 1:

it seems that you did not use the Bundle which carries the data. Intent only calls for the next activity. Bundle must be included.

like:

Bundleb=newBundle();
b.putString("ANSWER", answer);

IntentintObj=newIntent(Question.this, Level1.class);
b.putExtras(b);
startActivity(intObj);

and in the next class. use this to get the data passed:

Bundleb=newBundle();

    b = getIntent().getExtras();
   StringGotanswer= b.getString("ANSWER");

and use the string Gotanswer to use it.

BUT one more thing, if you wanna pass the string ANSWER to the next class, it would be impossible in this code because inside your every condition, there is a line that starts the next class such as:

IntentmyIntent=newIntent("com.turtleexploration.LEVEL1");
        startActivity(myIntent);

doing this will start the next class without passing through the intObj code below. this is if I'm not mistaken. :)

plus, instead of using If-Else-If , switch is much better for this kind.
