自定义listView中的SeekBar始终返回最后一个位置

Question

首先，抱歉英语不好。

我在自定义listView中有一个seekBar（在一个片段中），它显示得很好，获得了propper值，但是当我尝试更改它们时，它总是尝试更改最后一个seekBar的值。

这是适配器上的getView方法

public View getView(int position, View convertView, final ViewGroup parent) {
        View v = convertView;

        if(convertView==null){
            LayoutInflater linf=(LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v=linf.inflate(R.layout.activity_single_option,null);
        }

        soa=getItem(position);

        TextView textView=(TextView)v.findViewById(R.id.singleOptionTextView);
        textView.setText(soa.getTitle());

        SeekBar seekBar=(SeekBar)v.findViewById(R.id.singleOptionSeekBar);
        seekBar.setMax(soa.getSeekBarMax());
        seekBar.setProgress(soa.getValue());

        seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            int prog=0;
            SystemManager systemManager=new SystemManager(activity);
            boolean status;
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                prog=progress;
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
                Log.d("onStopTrackingTouch",soa.getTitle());
                switch (soa.getTitle()){
                    case "Brillo":
                        systemManager.setBrightness(prog);
                        break;
                    case "WIFI":
                        status = prog == 1;
                        systemManager.toggleWifi(status);
                        break;
                    case "Datos Moviles":
                        status = prog == 1;
                        systemManager.toggleMobileData(status);
                        break;
                    case "Bluetooth":
                        status = prog == 1;
                        systemManager.toggleBluetooth(status);
                        break;
                }

            }
        });

        return v;
    }

我将Log.d放在onStopTrackingTouch方法上，这样我就可以看到我选择了哪个选项，并且始终是最后一个选项。

这是我设置每个listView项目的地方

在这段代码中，我总是试图改变蓝牙

我找到了自己的答案，我需要保存seekBar的位置，所以getView方法就这样结束了。

 public View getView(int position, View convertView, final ViewGroup parent) {
        View v = convertView;
        final int pos=position;

        if(convertView==null){
            LayoutInflater linf=(LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v=linf.inflate(R.layout.activity_single_option,null);
        }

        soa=getItem(position);

        TextView textView=(TextView)v.findViewById(R.id.singleOptionTextView);
        textView.setText(soa.getTitle());

        SeekBar seekBar=(SeekBar)v.findViewById(R.id.singleOptionSeekBar);
        seekBar.setMax(soa.getSeekBarMax());
        seekBar.setProgress(soa.getValue());

        seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
            SingleOptionActivity soa=getItem(pos);
            int prog=0;
            SystemManager systemManager=new SystemManager(activity);

            boolean status;
            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                prog=progress;
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {
                Log.d("onStopTrackingTouch",soa.getTitle());
                switch (soa.getTitle()){
                    case "Brillo":
                        systemManager.setBrightness(prog);
                        break;
                    case "WIFI":
                        status = prog == 1;
                        systemManager.toggleWifi(status);
                        break;
                    case "Datos Moviles":
                        status = prog == 1;
                        systemManager.toggleMobileData(status);
                        break;
                    case "Bluetooth":
                        status = prog == 1;
                        systemManager.toggleBluetooth(status);
                        break;
                }

            }
        });

        return v;
    }
