i guess i need an image for each box that matches the board b/c onclick doesn't respond to an image with no "android:background" (basically no image)...


i think because you're setting height and width to wrap and not giving it an image, its height and width are probably 0. hence you can't actually click it. try changing the opacity and setting a height/width but it might not be able to handle a click if it's invisible.

so i'm stuck here

in my selection screen, whenever the user clicks on the default "X" (top icon), the icons swap and vice versa.



i'm using a boolean flag to keep track of the previous icon that was clicked..

when the user is on the "board" screen, the icon that was last clicked/selected should appear first (player 1 always goes first) ...i've tried accessing the public variable by creating a new object but it only retrieves the global variable that was initialized, not the modified value so the boolean flag would always be true.

i have no idea what you're talking about. if you can't access a variable, you're storing it in the wrong place. why are you even using this flag? i'm confused. i think Views have some property you can use to store data. i dont remember the name off hand. data, metadata, tag, or something like that.

Tags

Unlike IDs, tags are not used to identify views. Tags are essentially an extra piece of information that can be associated with a view. They are most often used as a convenience to store data related to views in the views themselves rather than by putting them in a separate structure.

this is my code for the first Activity posted above...maybe it's a really bad design. i'm using the flag so the program knows which icon to swap next... the icons are swapped every time you press the top one. idk it's just a neat feature to have when the user wants to choose X over O, or vice versa and he can switch back by simply reclicking the top icon if he suddenly decides to stay with his initial selection. unless this is not the proper way to implement such functionality.

Code
private boolean isX = true;
View v;
View v1;
View back_view;
View start_view;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_versus);

v = findViewById(R.id.x_versus);
v.setOnClickListener(this);

v1 = findViewById(R.id.o_versus);
v1.setOnClickListener(this);

back_view = findViewById(R.id.backBtn);
back_view.setOnClickListener(this);

start_view = findViewById(R.id.startBtn);
start_view.setOnClickListener(this);

}

public void onClick(View view) {
// if player 1 button is clicked
if (view.getId() == R.id.x_versus) {
// if player 1's icon is X (by default it is X)
if (isX) {
// change X to O when clicked
view.setBackgroundResource(R.drawable.o_button);
// change player 2 icon to X
v1.setBackgroundResource(R.drawable.x);
// player 1 button is no longer X
isX = false;
// if player one button is O
} else {
// change O to X
view.setBackgroundResource(R.drawable.x_button);
// change player 2 icon to O
v1.setBackgroundResource(R.drawable.o);
// player 1 button is X
isX = true;
}
}
else if (view.getId() == R.id.backBtn) {
Intent intent = new Intent(this, PlayActivity.class);
this.startActivity(intent);
}
else if (view.getId() == R.id.startBtn) {
Intent intent = new Intent(this, StartActivity.class);
this.startActivity(intent);
}
}


the swap:

i'm still not clear what your problem is. you shouldn't have any problems accessing the flag. so where are you trying to access the flag from? if you're trying to access it from another activity, you should pass it to the activity via your intent.

yes i'm trying to access the flag from another activity but i tried doing that, it would always return true. i haven't looked into Tags yet. maybe that would be an easier solution.

show me the code where you're passing it via the intent and the code in your new activity where you read from it.

i dont see how a tag will help since the tag is on a view that isn't in your new activity.

the above code is from the "VersusActivity" Class.

then I had the following in "StartActivity":

Code
VersusActivity va = new VersusActivity();
boolean isX = va.isX;


i'm not sure what you mean by passing the boolean via Intent. I've only used Intent for starting a new Activity. So is the boolean not necessary? I need to know the selected Icon by Player 1 so when the game starts, it knows which icon to use first, X or O..

that's your problem. obviously if you create a new activity it's not going to be the same one you just used.

that's exactly what you want to use. you want to pass the data when starting the new activity. read up on intents.

is there another way to allow the user to click a box only once besides what i'm doing in the following code? or is my method good enough?
box1_clicked is a boolean initialized to false..basically a flag to indicate the box has been clicked.

Code
public void onClick(View view) {

if (view == box1_view && !box1_clicked) {
box1_clicked = true;
....
