Can ToggleButton change the functionality of other buttons in the same Activity?

Question

To summarize, can ToggleButton change what other buttons in the activity do when they switch? If yes, then a more specific explanation of what I want to do is below:

Basically there are three buttons and a toggle button. When the switch switches, pressing any of the three buttons will take a picture and “save it” for that button. When turned off, pressing any of the three buttons simply displays their images. I think I can determine the part of the camera capture, but I need some direction when it comes to the switch.

Any help is appreciated, and I can explain it if necessary.

Answer 1

Create a boolean value, for example isToggleOn, which trueor falsedepending on ToggleButton. Then for each of your buttons, you can simply:

Button button1 = (Button) findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if(isToggleOn){
            //do one thing
        } else {
            //do other thing
        }      
    }
});

Answer 2

What I would do is keep flags for each state at the class level, for example:

public class MyClass {
   private static final int STATE_SAVE = 0;
   private static final int STATE_DISPLAY = 1;
   private int currentState = STATE_DISPLAY; 
   // I made this default for the example, 
   // you should use what makes sense to your project.
}

Then inside the toggle button you can set a flag. To paraphrase this code, since I do not have an open editor:

toggleButton.setOnToggleListener(new OnToggleListener() {
   @Override
   public void onToggled(boolean toggled) {
      if(toggled) {
         currentState = STATE_SAVE;
      } else {
         currentState = STATE_DISPLAY;
      }
   });

Now that the buttons are pressed, you can switch to the state to perform the action:

button.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
      if(currentState == STATE_SAVE) {
         // Save the image.
      } else if (currentState == STATE_DISPLAY) {
         // Display the image.
      }
   });

For your purpose, I would suggest defining two sets of listeners - two for each of the three buttons, and then continue to change between them.
