按下对象后，将TextView文本更改为“普通”

Question

I currently have a ListView which uses a CustomAdapter to display the information from my Firebase Database. Which looks like the following:

Upon creation I want the text in the green boxes (The ListView Items) to be bold. Once the user presses on that ListView item I want the text to go to Normal, unbolded.

I want it to work similar to an email. When you get a new email the title is bold and once that email is opened and you go back to your inbox the text is the Normal, unbolded.

The following is all my relevant code:

MyJobsFragment, SelectItem

// Press the object and display the information and sign the job of with signature pad

    jobListViewMyAcJobs.setOnItemClickListener(new AdapterView.OnItemClickListener()
    {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id)
        {
            ActiveJobDetailsFragment activeJobDetailsFragment = new ActiveJobDetailsFragment();
            Bundle bundle = new Bundle();
            bundle.putSerializable("Job", adapterActiveJobs.mData.get(position));
            bundle.putSerializable("JobId", adapterActiveJobs.mDataKeys.get(position));
            activeJobDetailsFragment.setArguments(bundle);
            getFragmentManager().beginTransaction().replace(R.id.content, activeJobDetailsFragment).addToBackStack(host.getCurrentTabTag()).commit();
        }
    });

MyCustomAdapter

public class MyCustomAdapter extends BaseAdapter
    {
        private ArrayList<JobInformation> mData = new ArrayList<>();
        private ArrayList<JobInformation> mDataOrig = new ArrayList<>();
        private ArrayList<String> mDataKeys = new ArrayList<>();

        private LayoutInflater mInflater;

        ... Removed Code ...

        @Override
        public View getView(final int position, View convertView, ViewGroup parent)
        {
            // Bid on holder
            MyJobsFragment.MyCustomAdapter.GroupViewHolderBidOn holderBidOn;
            // Accepted holder
            final MyJobsFragment.MyCustomAdapter.GroupViewHolderAccepted holderAccepted;
            // Completed holder
            MyJobsFragment.MyCustomAdapter.GroupViewHolderCompleted holderCompleted;

            if (convertView == null)
            {
                // Bid on
                if (host.getCurrentTab() == 0)
                {
                    convertView = mInflater.inflate(R.layout.job_info_bid_on, null);
                    holderBidOn = new MyJobsFragment.MyCustomAdapter.GroupViewHolderBidOn();

                    holderBidOn.textViewJobName = convertView.findViewById(R.id.textName);
                    holderBidOn.textViewJobDescription = convertView.findViewById(R.id.textDesc);

                    holderBidOn.textViewJobName.setText(mData.get(position).getAdvertName());
                    holderBidOn.textViewJobDescription.setText(mData.get(position).getAdvertDescription());

                    convertView.setTag(holderBidOn);
                }
                // Accepted
                else if (host.getCurrentTab() == 1)
                {
                    convertView = mInflater.inflate(R.layout.job_info_accepted, null);
                    holderAccepted = new MyJobsFragment.MyCustomAdapter.GroupViewHolderAccepted();

                    holderAccepted.textViewJobName = convertView.findViewById(R.id.textName);
                    holderAccepted.textViewDescription = convertView.findViewById(R.id.textDesc);

                    holderAccepted.textViewJobName.setText(mData.get(position).getAdvertName());
                    if(text != null)
                    {
                        text.setTypeface(null, Typeface.BOLD);
                    }

                    holderAccepted.textViewDescription.setText(mData.get(position).getAdvertDescription());
                    // TODO - Was going to add the the users bid into this here, however it's difficult as the bid isnt stored in the jobs table
                    // TODO - I tried to add it in, looped through the bids table and found the bids with the mDataKeys. But it always displayed the last value.

                    convertView.setTag(holderAccepted);
                }
                // Completed

Answer 1

Well there multiple ways of achieving that. I would suggest you to add a field in your JobInformation class, something like

public class JobInformation{
    .
    .
    .
    .
    . // other fields

    private boolean isSelected;

    public boolean isSelected() {
        return isSelected;
    }
    public void setSelected(boolean selected) {
        isSelected = selected;
    }

    .
    .
    . // Other getters/setters

}

Now you need to set this field when you click an item, in your onItemClick function do this

public void onItemClick(AdapterView<?> parent, View view, int position, long id)
        {
            ActiveJobDetailsFragment activeJobDetailsFragment = new ActiveJobDetailsFragment();
            Bundle bundle = new Bundle();
            adapterActiveJobs.mData.get(position).setSelected(true); // add this line in your code
            bundle.putSerializable("Job", adapterActiveJobs.mData.get(position));
            bundle.putSerializable("JobId", adapterActiveJobs.mDataKeys.get(position));
            activeJobDetailsFragment.setArguments(bundle);
            getFragmentManager().beginTransaction().replace(R.id.content, activeJobDetailsFragment).addToBackStack(host.getCurrentTabTag()).commit();
        }

finally in your getView method in your custom adapter, check for isSelected field and style your textview accordingly, add this in your getView method.

if(mData.get(position).isSelected()){
    // set your textview typeface to normal
}
else{
    // set your texview typeface to bold.
}

and you would need to call adapter.notifyDataSetChanged() whenever you update selected variable so that your getView is called.
