动态地将文本视图添加到listview项目

我有这个项目的arryalist,每个项目有小时字符串和分钟字符串。我可以将分钟分成数组,每分钟我想在clicklistener上添加textview。

我已经为listview实现了arrayadapter。一切都像预期的那样工作但只有一件事:我没有看到所有的文本视图,因为它们没有在显示器的末尾正确显示。

ListView行项目布局包含LinearLayout和textview以显示小时数。

listview适配器的代码:

public class DotazAdapter extends ArrayAdapter<Hours> {

    private final ArrayList<Hours> model;
    private final Context context;

    public DotazAdapter(Context context, ArrayList<Hours> model) {
        super(context, R.layout.hours_minutes,model);
        this.model=model;
        this.context=context;
        // TODO Auto-generated constructor stub
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View row = null;
        row = inflater.inflate(R.layout.hours_minutes, parent,false);
        LinearLayout riadok = (LinearLayout)row.findViewById(R.id.horny);

        TextView hodiny = (TextView)row.findViewById(R.id.hodinyBTV);
        hodiny.setText(model.get(position).getHour());

        String[] minuty = model.get(position).getMinutes().split(" ");

        for(int i = 0; i<minuty.length;i++){
            final TextView minutka = new TextView(context);

            minutka.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            minutka.setText(minuty[i]+"  ");


            minutka.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    Toast.makeText(context, "Stlacil si riadok "+position+ " a cislo v riadku :", Toast.LENGTH_SHORT).show();

                }
            });

            riadok.addView(minutka, );
        }
        return row; 
    }

}

listitem的布局:

xml version=1.0 encoding=utf-8
LinearLayout xmlnsandroid=httpschemas.android.comapkresandroid
    androidid=@+idhorny
    androidlayout_width=match_parent
    androidlayout_height=wrap_content

        TextView
            androidid=@+idhodinyBTV
            androidlayout_width=wrap_content
            androidlayout_height=wrap_content
            androidlayout_marginRight=5dp
            androidbackground=#F00C0C
            androidtextColor=#FFFFFF
            androidtextSize=18sp



LinearLayout
