如何从Android将字符串插入现有行到数据库

Question

I have a row obtained from data base and I am using textview to display them. but I have a button which gives a string.when it is onclicked and I want that data to be posted into an existing same row.

public class RecyclerViewAdapter extends 
RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>
{

Context context;
int attempt=1,attempt1=2;
public static final String decline="0";
public static final String KEY_DECLINE = "decline";
public static final String accept="1";
public static final String KEY_ACCEPT = "accept";
List<GetDataAdapter> getDataAdapter;


public RecyclerViewAdapter(List<GetDataAdapter> getDataAdapter, Second context){

    super();

    this.getDataAdapter = getDataAdapter;
    this.context = context;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.container_customer, parent, false);

    ViewHolder viewHolder = new ViewHolder(v);

    return viewHolder;
}

@Override
public void onBindViewHolder(final ViewHolder holder, int position) {

    final GetDataAdapter getDataAdapter1 =  getDataAdapter.get(position);
    holder.NameTextView.setText("Name:"+getDataAdapter1.getName());
    holder.IdTextView.setText("ID:"+getDataAdapter1.getId());
    holder.PhoneNumberTextView.setText("Problem:"+getDataAdapter1.getPhone_number());
    holder.SubjectTextView.setText("Phone:"+getDataAdapter1.getSubject());
    holder.address.setText("Address"+getDataAdapter1.getAddress());

        holder.accept.setOnClickListener(

You can insert data to database like this

 db.insert(TABLE_NAME, null, getMemberContentValues(object)); 

private ContentValues getMemberContentValues(Object object) {

        if (object== null)
            return null;

        ContentValues contentValues = new ContentValues();

        contentValues.put(Column_name1, object.getProperty1());
        contentValues.put(Column_name2, object.getProperty2());

        return contentValues;
    }
