Add new TextView to ListView

Question

I want to add new TextView to my ListView which is already in my XML file. Just before add them, I setText() with static String[]. I've tried a lot of solutions but I got sometimes an exception about TextView id, and other times this one:

My class:

public class ListObjet{
    private ImageButton mButton;
    private EnvoiMailActivity mEnvoiMailActivity;
    private LayoutInflater inflater;
    private ListView mList;
    private int ressource;

    public ListObjet(EnvoiMailActivity pEnvoiMailActivity, int resourceId) {
        this.ressource = resourceId;
        this.mEnvoiMailActivity = pEnvoiMailActivity;
        this.inflater = LayoutInflater.from(mEnvoiMailActivity);

        this.mList = (ListView) inflater.inflate(this.ressource, null);
        this.mButton = (ImageButton) mEnvoiMailActivity.findViewById(R.id.listobjet);
        this.mButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AlertDialog.Builder myList = new AlertDialog.Builder(mEnvoiMailActivity);

                myList.setView(creatView());
                AlertDialog alert = myList.create();
                alert.show();
            }
        });
    }


    private View creatView(){
        ScrollView mScrollView = new ScrollView(mEnvoiMailActivity);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(mEnvoiMailActivity, this.ressource, Conf.OBJET_PROPOSE);
        this.mList.setAdapter(adapter);
        for (int i = 0; i < Conf.OBJET_PROPOSE.length; i++ ) {
            TextView item = new TextView(mEnvoiMailActivity);
            item.setText(Conf.OBJET_PROPOSE[i]);
            mList.addView(item);
        }
        mList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //todo
            }
        });
        mScrollView.addView(mList);


        return mScrollView;
    }
}

I changed my code:

private View creatView(){
    ScrollView mScrollView = new ScrollView(mEnvoiMailActivity);
    ArrayAdapter<TextView> adapter = new ArrayAdapter<TextView>(mEnvoiMailActivity, this.ressource);
    this.mList.setAdapter(adapter);
    for (int i = 0; i < Conf.OBJET_PROPOSE.length; i++ ) {
        TextView item = new TextView(mEnvoiMailActivity);
        item.setText(Conf.OBJET_PROPOSE[i]);
        adapter.add(item);
    }

This exception occured:

Answer 1

Instead of assigning TextView dynamically, just pass id of layout which contains on TextView. You can create custom layout having only TextView or you can use default template layout provided by android sdk itself. example:

android.R.layout.simple_list_item_1

full example:

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(context,android.R.layout.simple_list_item_1,list);
