How To Get Selected Chips From Chipgroup?

I search a lot on internet but couldn't find the exact solution. Here is the link that i last tried from SO. Get selected Chips from a ChipGroup I want to get selected chips from c

Solution 1:

Starting with the version 1.2.0 you can use the method chipGroup.getCheckedChipIds()

List<Integer> ids = chipGroup.getCheckedChipIds();
for (Integer id:ids){
      Chip chip = chipGroup.findViewById(id);
      //....
}

OLD ANSWER with 1.1.0:

currently there isn't a direct API to get the selected chips. However you can iterate through the children of the ChipGroup and check chip.isChecked().

ChipGroupchipGroup= findViewById(R.id.....);
   for (int i=0; i<chipGroup.getChildCount();i++){
      Chipchip= (Chip)chipGroup.getChildAt(i);
      if (chip.isChecked()){
         //this chip is selected..... 
      }
    }

Solution 2:

the solution I used in Kotlin with data binding

mBinding?.chipGroup?.children
            ?.toList()
            ?.filter { (it as Chip).isChecked }
            ?.forEach { //here are your selected chips as 'it' }

And here is how I got just titles

mBinding?.chipGroup?.children
            ?.toList()
            ?.filter { (it asChip).isChecked }
            ?.joinToString(", ") { (it asChip).text }

Solution 3:

Get selected chip's text in a chip group

To get selected chip's text from chipgroup, you can use this one liner in Kotlin:

val selectedChipText = parentChipGroup.findViewById<Chip>(parentChipGroup.checkedChipId).text.toString()

Solution 4:

I used below mentioned method to detect the selected chips in chipGroup.

for (chipTitle in stringList) {
    valchip= Chip(chipGroup.context)
    chip.text = chipTitle
    chip.tag = chipTitle
    chip.isClickable = true
    chip.isCheckable = true
    chip.setOnCheckedChangeListener { _, isChecked ->
        if (isChecked){
            Log.e(TAG, chipTitle)
        }
    }
    chipGroup.addView(chip)
}
chipGroup.isSingleSelection = true

Solution 5:

Now using Material Chip it is very easy task. Here example of getting chip's text from a dialog

       val builder = AlertDialog.Builder(requireContext())
       builder.setTitle("Filter")
       val mView = FilterOptionLayoutBinding.inflate(layoutInflater)
       builder.setView(mView.root)

       builder.setPositiveButton(android.R.string.ok) { d, p ->
           mView.chipGroup.checkedChipIds.forEach {
               val chip = mView.root.findViewById<Chip>(it).text.toString()
               checkedChipsText.add(chip)
           }
           d.dismiss()
       }
       builder.setNegativeButton(android.R.string.cancel) { d, _ ->
           d.cancel()
       }
       builder.create()
       builder.show()

now chip hold text of all chips
