android - 如何在适配器类中设置值列表项并在 android 中单击按钮获取值

Question

适配器类:

public List<TSPDataModel> employeeData;
    private Context mContext;
    private LayoutInflater mInflater;
    RadioGroup radiogroupbutton;
    String[] data = {"Document not clear","Adress is not Visibile","Photo is not pasted","Signature is not Avilable"};
    String   value;
    public TSPListDocumentadapter(Context context, int textViewResourceId,
                                  List<TSPDataModel> objects)

    {
        this.employeeData = objects;
        this.mContext = context;
        mInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        final ViewHolder holder;

        if (convertView == null) {
            holder = new ViewHolder();
            convertView = mInflater.inflate(R.layout.tspdocumentlistitem, null);
            holder.relatvie1=(RelativeLayout)convertView.findViewById(R.id.relatvie1);
            holder.txtName = (TextView) convertView.findViewById(R.id.textView1);
            holder.accecpt = (ImageView) convertView.findViewById(R.id.imageButton);
            holder.reject = (ImageView) convertView.findViewById(R.id.imageButton2);
            holder.statustextview = (TextView) convertView.findViewById(R.id.statustextview);
            holder.poaedittext=(TextView) convertView.findViewById(R.id.poieditext);
           holder.poaedittext=(TextView)convertView.findViewById(R.id.poaedittext);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }
        holder.txtName.setText(employeeData.get(position).getName());
        holder.poaedittext.setText(employeeData.get(position).getPoa());

        holder.accecpt.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                holder.statustextview.setText("Accepted");

                employeeData.get(position).setSelected(true);
                employeeData.get(position).getOrderId();
                holder.relatvie1.setBackgroundResource(R.color.acceptedcolor);

            }
        });

        holder.reject.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showdilog();
                holder.statustextview.setText("Rejected");
                employeeData.get(position).setSelected(false);
                employeeData.get(position).setReasone(value);
                holder.relatvie1.setBackgroundResource(R.color.rejectcolor);
            }
        });


        return convertView;
    }

    static class ViewHolder {
        TextView txtName;
        ImageView reject;
        ImageView accecpt;
        TextView statustextview;
        TextView poiedittext;
        TextView poaedittext;
        RelativeLayout relatvie1;
    }

    public int getCount() {
        return employeeData.size();
    }

    public TSPDataModel getItem(int position) {
        return employeeData.get(position);
    }

    public long getItemId(int position) {
        return 0;
    }


    public void showdilog() {
        final Dialog dialog = new Dialog(mContext);
        dialog.setContentView(R.layout.layoutpopup);
        radiogroupbutton = (RadioGroup) dialog.findViewById(R.id.radio_gp_day);
        ListView listview = (ListView) dialog.findViewById(R.id.radio_slot_list);
        Button setbutton = (Button) dialog.findViewById(R.id.setbutton);
        List<String> list = new ArrayList<String>();
        ArrayAdapter<String> myadpter = new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_single_choice, data);
        for (int i = 0; i < data.length; i++) {
            list.add(data[i]);
        }
        listview.setAdapter(myadpter);
        listview.setItemsCanFocus(false);
        listview.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                value = data[position];
                Toast.makeText(mContext, value, Toast.LENGTH_LONG).show();
            }
        });
        setbutton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(mContext, value, Toast.LENGTH_LONG).show();
                dialog.dismiss();


            }
        });

        dialog.show();
    }

这个按钮在我的 Activity 类中点击:

    @Override
    public void onClick(View view) {
        if (view.getId() == R.id.button1) {
            try {

                List<TSPDataModel> empData = adapter.employeeData;
                System.out.println("Total Size :" + empData.size());

                for (TSPDataModel employeeModel : empData) {
                    if (employeeModel.isSelected()) {
              Toast.makeText(TSPDocumentListActvity.this, employeeModel.getName(), Toast.LENGTH_LONG).show();
                    } else {

String Reasonse=   employeeModel.getresonse() ;                

                        Toast.makeText(TSPDocumentListActvity.this, "false" + employeeModel.getName(), Toast.LENGTH_LONG).show();
                    }
                }


            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    }

首先，我在 Listview 中打印数据，然后每个 ListView 项目都有接受和拒绝按钮，当我们点击接受时，不会有任何警报，只有拒绝按钮原因会询问哪个出现在弹出窗口的列表项上，我想得到那个选择按钮点击 actvity 的原因，但我总是得到空值，请帮助我哪里做错了

Answer 1

将您的拒绝按钮和 showDialog 代码更改为

holder.reject.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showdilog(position);
                holder.statustextview.setText("Rejected");
                holder.relatvie1.setBackgroundResource(R.color.rejectcolor);
            }
        });

和 showDuallog 到

public void showdilog(int list_position) {
        final Dialog dialog = new Dialog(mContext);
        dialog.setContentView(R.layout.layoutpopup);
        radiogroupbutton = (RadioGroup) dialog.findViewById(R.id.radio_gp_day);
        ListView listview = (ListView) dialog.findViewById(R.id.radio_slot_list);
        Button setbutton = (Button) dialog.findViewById(R.id.setbutton);
        List<String> list = new ArrayList<String>();
        ArrayAdapter<String> myadpter = new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_single_choice, data);
        for (int i = 0; i < data.length; i++) {
            list.add(data[i]);
        }
        listview.setAdapter(myadpter);
        listview.setItemsCanFocus(false);
        listview.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
        listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                value = data[position];
                employeeData.get(list_position).setSelected(false);
                employeeData.get(list_position).setReasone(value);
                Toast.makeText(mContext, value, Toast.LENGTH_LONG).show();
            }
        });
        setbutton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(mContext, value, Toast.LENGTH_LONG).show();
                dialog.dismiss();


            }
        });

        dialog.show();
    }
