Recognizing A Button From A Dynamic View

I have written this code for a dynamic layout where I am using this loop to generate a pair of buttons (this is the part of code where I generate them) for(int i = 1; i <= 2 ;

Solution 1:

I assume that you are using the button tags in your click processing. To keep the tag data and add the needed wiring between buttons, you can create a data structure that would serve as a tag:

staticclassButtonTag {
    String buttonType;
    Button partner;
    ButtonTag(Stringtype, Button button) {
        buttonType = type;
        partner = button;
    }
}

Then you could reorganize your setup code:

for(inti=1; i <= 2 ; i++) {
    Buttonbutton1=newButton(this);
    button1.setId(i);
    layout.addView(button1);

    Buttonbutton2=newButton(this);
    button2.setId(i);
    button2.setEnabled(false);
    button1.setTag(newButtonTag("age", button2));
    button2.setTag(newButtonTag("country", button1));
    layout.addView(button2);
}

The click processing will obviously need to be changed to cast getTag() to a ButtonTag instead of a String.

If you don't need the "age" and "country" information to distinguish button types, just set each button as the tag for the other.

EDIT:

With the latter scheme, here's how you would use this in a click listener:

publicvoidonClick(View v) {
    Objecttag= v.getTag();
    if (tag instanceof Button) {
        Buttonbtn= (Button) tag;
        btn.setEnabled(true);
        v.setEnabled(false);
    }
}

If you needed the "age" and "country" part of the tag for other reasons, the code would be only a little different:

publicvoidonClick(View v) {
    Objecttag= v.getTag();
    if (tag instanceof ButtonTag) {
        ButtonTagbTag= (ButtonTag) tag;
        bTag.partner.setEnabled(true);
        v.setEnabled(false);
    }
}

Solution 2:

I got a solution to the problem after referring to this question here ( find button by ID or TAG ), it solves the problem I was facing as such !

publicclassDynmaicViewExperimentActivityextendsActivityimplementsOnClickListener{

List<Button> buttons;

@OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        buttons = newArrayList<Button>();
        setDynamicContentViewOfThisPage();
    }

publicvoidonClick(View v) {
    // TODO Auto-generated method stubintbuttonType=0;
    if (v.getTag()=="age")
            buttonType = 1;
    elseif (v.getTag()=="country")
            buttonType = 2;
    switch (buttonType) {
        case1:
            for(Button b: buttons) {
                if(b.getId() == v.getId() && b.getTag().equals("country")){
                    b.setEnabled(true);
                    v.setEnabled(false);
                    }
        case2:
            for(Button b: buttons) {
                if(b.getId() == v.getId() && b.getTag().equals("age")){
                    b.setEnabled(true);
                    v.setEnabled(false);
                    }
                }
            }
        }


privatevoidsetDynamicContentViewOfThisPage() {
    // Defining the Scroll View and the LinearLayoutScrollViewsv=newScrollView(this);
    LinearLayoutl=newLinearLayout(this);
    l.setOrientation(LinearLayout.VERTICAL);
    sv.addView(l);

                                for(inti=1; i <= 2 ; i++) {

                                  Buttonbutton1=newButton(this);
                                  button1.setId(i);
                                  button1.setTag("age");
                                  buttons.add(button1);
                                  l.addView(button1);

                                  Buttonbutton2=newButton(this);
                                  button2.setId(i);
                                  button2.setTag("country");
                                  buttons.add(button2);
                                  l.addView(button2);

                                  button.setOnClickListener(this);
                                  button2.setOnClickListener(this);

    // Set the content View to thisthis.setContentView(sv);
    }
   }
 }
