App crashed when trying to update the retrieved value from SQLite in ListView

In Edit_WorkDetails Activity, it has a ListView where the data were actually retrieved from SQLite. When the list is clicked, it will intent to Edit_Details for edit.

This is how my Edit_WorkDetails Activity looked like.

enter image description here

When the save button in Edit_Details clicked, the app crashed.

Edit_WorkDetails

  listViewUpdate.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> listView, View view,
                                    int position, long id) {
                mClickedPosition=position; // update
                // Get the cursor, positioned to the corresponding listview_item_row in the result set
                Cursor cursor = (Cursor) listView.getItemAtPosition(position);

                // Get the state's capital from this listview_item_row in the database.
                ID =
                        cursor.getLong(cursor.getColumnIndexOrThrow("_id"));
                Intent intent = new Intent(getActivity(), Edit_Details.class);
                intent.putExtra("ID", ID);
                startActivityForResult(intent, PROJECT_REQUEST_CODE);


            }
        });

 @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) { // receive from Edit_Details and populate ListView 
        if (resultCode == Activity.RESULT_OK) {
            if(requestCode==PROJECT_REQUEST_CODE) {
                ReceiveProject = data.getStringExtra("project1");
                ReceiveDescription = data.getStringExtra("description");
                ReceiveProgress = data.getIntExtra("progress", 0);
                ReceiveTimeIn = data.getStringExtra("timeIn");
                ReceiveTimeOut = data.getStringExtra("timeOut");
                if (mClickedPosition == -1) {  // if icon clicked
                    if (objCustomBaseAdapter != null)
                        objCustomBaseAdapter.addNewItem(ReceiveProject, ReceiveDescription, ReceiveProgress, ReceiveTimeIn, ReceiveTimeOut);

                } else {  // update list
                    if (objCustomBaseAdapter != null)
                        objCustomBaseAdapter.changeItem(mClickedPosition, ReceiveProject, ReceiveDescription, ReceiveProgress, ReceiveTimeIn, ReceiveTimeOut);

                }
            }

        }

    }

Edit_Details.java

  save.setOnClickListener(new View.OnClickListener() {  // return values to Edit_WorkDetails and update the list
            @Override
            public void onClick(View v) {
                Intent returnIntent = new Intent();
                project1 = Project2.getSelectedItem().toString();
                description = Description.getText().toString();
                progress = seekBar.getProgress();
                returnIntent.putExtra("project1", project1);
                returnIntent.putExtra("description", description);
                returnIntent.putExtra("progress", progress);
                Toast.makeText(getApplicationContext(), progress + "", Toast.LENGTH_LONG).show();
                returnIntent.putExtra("timeIn", timeIn);
                returnIntent.putExtra("timeOut", timeOut);
                setResult(Activity.RESULT_OK, returnIntent);
                finish();

            }


        });

    }

CustomBaseAdapter

 public void changeItem(int mPosition,String Project,String Description,int Percentage,String TimeIn,String TimeOut)
    {
        SearchResults obj = new SearchResults();
        obj.setProject(Project);
        obj.setDescription(" Work Description : " + Description);
        obj.setProgress(" Progress : " + Percentage);
        obj.setTimeIn(" Time In : " + TimeIn);
        obj.setTimeOut(" Time Out : " + TimeOut);
        searchArrayList.set(m,obj);
        this. notifyDataSetChanged();
    }

AND finally SearchResult.java

public class SearchResults {

    private String weather = "";
    private String date = "";
    private String status = "";
    private String timeIn="";
    private String timeOut="";
    private String project="";
    private String description="";
    private String progress="";

    public void setWeather(String weather) {
        this.weather = weather;
    }

    public String getWeather() {
        return weather;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getDate() {
        return date;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getStatus() {
        return status;
    }

    public void setTimeIn(String timeIn) {
        this.timeIn = timeIn;
    }

    public String getTimeIn() {
        return timeIn;
    }

    public void setTimeOut(String timeOut){
       this.timeOut=timeOut;
    }

    public String getTimeOut()
    {
        return timeOut;
    }

    public void setProject(String project){
        this.project=project;
    }

    public String getProject()
    {
        return project;
    }

    public void setProgress(String progress){
        this.progress=progress;
    }

    public String getProgress()
    {
        return progress;
    }

    public void setDescription(String description){
        this.description=description;
    }

    public String getDescription()
    {
        return description;
    }

}

Error logCat

(CustomBaseAdapter.java:101)

 searchArrayList.set(m,obj);

(Edit_WorkDetails.java:141)

 objCustomBaseAdapter.changeItem(mClickedPosition, ReceiveProject, ReceiveDescription, ReceiveProgress, ReceiveTimeIn, ReceiveTimeOut);

Why I will getting such error ? It is impossible to edit the retrieved value from SQLite to ListView ?
