How to set multiple tags to a button?

Question

I have 16 buttons and I tag them to pair some terms set to buttons and imported from sqlite database. So, I tag them like this:

// labelForButton and tagForButton        class MyStruct {        public MyStruct (String lab, String t){         label = lab;         tag = t;     }        private String label;        private String tag;        }  mDbHelper.open();              Cursor c = mDbHelper.getSpojnice(generateWhereClause());              ArrayList<MyStruct> labelsA = new ArrayList<MyStruct>();             ArrayList<MyStruct> labelsB = new ArrayList<MyStruct>();              labelsA.add(new MyStruct(c.getString(2), "1")); // this tag should be the same to button that matches             labelsB.add(new MyStruct(c.getString(3), "1"));             labelsA.add(new MyStruct(c.getString(4), "2"));             labelsB.add(new MyStruct(c.getString(5), "2"));             labelsA.add(new MyStruct(c.getString(6), "3"));             labelsB.add(new MyStruct(c.getString(7), "3"));             labelsA.add(new MyStruct(c.getString(8), "4"));             labelsB.add(new MyStruct(c.getString(9), "4"));             labelsA.add(new MyStruct(c.getString(10), "5"));             labelsB.add(new MyStruct(c.getString(11), "5"));             labelsA.add(new MyStruct(c.getString(12), "6"));             labelsB.add(new MyStruct(c.getString(13), "6"));             labelsA.add(new MyStruct(c.getString(14), "7"));             labelsB.add(new MyStruct(c.getString(15), "7"));             labelsA.add(new MyStruct(c.getString(16), "8"));             labelsB.add(new MyStruct(c.getString(17), "8"));              Collections.shuffle(labelsA);             Collections.shuffle(labelsB);              a1.setText(labelsA.get(0).label);             a1.setTag(labelsA.get(0).tag);             a1.setOnClickListener(clickListener);             b1.setText(labelsB.get(0).label);             b1.setTag(labelsB.get(0).tag);             b1.setOnClickListener(clickListener);             a2.setText(labelsA.get(1).label);             a2.setTag(labelsA.get(1).tag);             a2.setOnClickListener(clickListener);             b2.setText(labelsB.get(1).label);             b2.setTag(labelsB.get(1).tag);             b2.setOnClickListener(clickListener); . . . . } } 

So, I need A1 and B1 to have same tags, also A2 and B2 and so on.

BUT, I also need for some other reason to all A buttons have tag for example "A" and all the B's "B". So, how to set multiple, in my case two, tags to one button?

EDIT:

I added this to my string.xml:

<item type="id" name="KOLONA1"/> <item type="id" name="KOLONA2"/> 

Then added tags:

a1.setTag(R.id.KOLONA1, labelsA.get(0).tag); b1.setTag(R.id.KOLONA2, labelsA.get(0).tag); 

Answer 1

If you need to add multiple tag into one view then you have to define the id for every tag in strings.xml file like:

<item type="id" name="section" /> <item type="id" name="hide_show" /> 

After adding the key you can use these keys in java file like below:

rowView.setTag(R.id.section,mSectionList.get(position)); rowView.setTag(R.id.hide_show,"close"); 

This will set the tag. At the time of getting tag you need to typecast the object which originally you set like:

String mSection=(String)rowView.getTag(R.id.section); String isOpen=(String)rowView.getTag(R.id.hide_show); 

Answer 2

You should use the setTag(int key, Object tag) method, which also takes a second parameter key. This will allow you to set multiple tags on each Button like this :

button.setTag(1,object1); button.setTag(2,object2);
