Question

So I’m figuring this stuff out in baby steps. And just got my button to toggle the way i want it. But now i want to add more buttons.

       `public class Menu extends Activity{
        ImageButton select;    
        int isClicked = 0;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
                // TODO Auto-generated method stub
                super.onCreate(savedInstanceState);
                setContentView(R.layout.main);

                select = (ImageButton)findViewById(R.id.select);
        select.setOnClickListener(new OnClickListener() {

                public void onClick(View v) {
                     if (isClicked == 0){
                        select.setImageResource(R.drawable.select_pressed);
                        isClicked = 1;
                     }
                     else{
                        select.setImageResource(R.drawable.select);
                        isClicked = 0;
                     }
                }});
             }
          }`

So say i were to copy that ImageButton method. Where exactly would i insert it, if i were going to use the code for a new button?

    `<ImageButton 
android:src="@drawable/select"
android:id="@+id/select"
android:layout_height="30dp"
android:layout_width="120dp"
android:background="@null"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true">
    </ImageButton>`

You can use the tag attribute on the button to store the state. Then you could put your state logic in a separate method like this:

public void changeState(View v) {
                     if (v.getTag() == "false"){
                        ((ImageButton)v).setImageResource(R.drawable.select_pressed);
                        v.setTag("true");
                     }
                     else{
                        ((ImageButton)v).setImageResource(R.drawable.select);
                        v.setTag("false");
                     }
                }});

This method you could call from each ImageButton’s clicklistener, without saving the state of numerous ImageButtons in the application context.
