how to get checked multiple values using custom adapter in android

Question

I have listview with custom adapter. Every element of this listview has checkbox. Standart function .isChecked() does not work.

someActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    btnShare.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            List<Boolean> listCheck;
            listCheck = new ArrayList<Boolean>();

            for (int i = 0; i < CA_main_trx.editModelArrayList.size(); i++){
                Boolean stat = CA_main_trx.editModelArrayList.get(i).getCheckShare();
                String nilaiPcs = CA_main_trx.editModelArrayList.get(i).getTextView_main_trx2();
                Log.d(TAG, "onClick: --a" + nilaiPcs);
                Log.d(TAG, "onClick: --a" + stat);
            }
        }
    });

CustomeAdapter

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder holder;
        final String TAG = "CA_Main_Trx : ";
...
        holder.checkShare.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                if(b){
                    String id = editModelArrayList.get(position).getTextView_main_trx0();
                    Log.d(TAG, "onCheckedChanged: True"+id);
                }
                else
                    Log.d(TAG, "onCheckedChanged: False");
            }

        });
...

model

package com.m.t;

public class EM_main_trx {

    private boolean checkShare;

    public Boolean getCheckShare() {return checkShare;}

    public void setCheckShare(Boolean checkShare) {
        this.checkShare = checkShare;
    }
}

When checked in custome Adapter i get the checked status. But when i get the data using button in my mainactivity i got stuck. just got null.

Some my reference :

Just update part of custome adapter to this :

@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
     editModelArrayList.get(position).setCheckShare(b);
}
