Question

我的片段中有ListView。我的列表项中有一些操作按钮。我的适配器如下所示

public class StatAdapter extends BaseAdapter {
    private Activity mActivity;
    private ArrayList<Stat> mData;
    private LayoutInflater mInflater;
    private Drawable drawableOffline,drawableOnline;

    public StatAdapter(Activity activity, ArrayList<Stat> data) {
        mActivity = activity;
        mData = new ArrayList<>();
        mData.addAll(data);

        mInflater = (LayoutInflater) mActivity.getSystemService(AppCompatActivity.LAYOUT_INFLATER_SERVICE);

         drawableOnline = activity.getResources().getDrawable(R.drawable.round_online);
         drawableOffline = activity.getResources().getDrawable(R.drawable.round_offline);
    }

    @Override
    public int getCount() {
        return mData.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(final int pPosition, View pView, ViewGroup pParent) {
        pView = mInflater.inflate(R.layout.list_stat, null,false);

        String name = mData.get(pPosition).getName();
        String first = name.substring(0, 1);

        TextView txtCount = pView.findViewById(R.id.txt_count);

        txtCount.setText(first);

        TextView txtName = pView.findViewById(R.id.txt_name);
        txtName.setText(name);
        TextView txtNumber = pView.findViewById(R.id.txt_number);
        txtNumber.setText("Number: "+mData.get(pPosition).getNumber());

        int onlineBg = ResourcesCompat.getColor(mActivity.getResources(), R.color.onlineBg, null);
        int offlineBg = ResourcesCompat.getColor(mActivity.getResources(), R.color.offlineBg, null);
        int white = ResourcesCompat.getColor(mActivity.getResources(), R.color.colorWhite, null);
        int black = ResourcesCompat.getColor(mActivity.getResources(), R.color.colorBlack, null);


        ImageView btnGetCSV = pView.findViewById(R.id.btnGetCSV);
        ImageView btnNotificationOff = pView.findViewById(R.id.btnNotificationOff);
        ImageView btnNotificationOn = pView.findViewById(R.id.btnNotificationOn);
        ImageView btnNumberDetails = pView.findViewById(R.id.btnNumberDetails);
        ImageView btnRemoveNumber = pView.findViewById(R.id.btnRemoveNumber);

        btnGetCSV.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(mActivity, "Get CSV", Toast.LENGTH_SHORT).show();

        btnNotificationOff.setOnClickListener(new View.OnClickListener() {

        TextView txtSatus = pView.findViewById(R.id.txt_status);

        txtTime.setText("Since " + mData.get(pPosition).getLastOnline());

        return pView;
    }

    public void setData(ArrayList<Stat> data) {

        mData.addAll(data);
        mActivity.runOnUiThread(new Runnable() {

您可以看到我的适配器中有一些操作按钮btnGetCSV等，我可以在其中实现onclick，但很难在适配器中实现某些功能，因此我正在考虑从Fragment进行操作。我是android的新手，不知道如何从片段中做到这一点。让我知道是否有人可以给我榜样。谢谢

您需要以这种方式在适配器中创建带有回调方法的接口“ OnMenuItemClickListener”。

public class StatAdapter extends BaseAdapter {
    private Activity mActivity;
    private ArrayList<Stat> mData;
    private LayoutInflater mInflater;
    private Drawable drawableOffline,drawableOnline;
    private OnMenuItemClickListener onMenuItemClickListener;

    public StatAdapter(Activity activity, ArrayList<Stat> data,OnMenuItemClickListener onMenuItemClickListener) {
        mActivity = activity;
        mData = new ArrayList<>();
        mData.addAll(data);
        this.onMenuItemClickListener = onMenuItemClickListener;

        mInflater = (LayoutInflater) mActivity.getSystemService(AppCompatActivity.LAYOUT_INFLATER_SERVICE);

         drawableOnline = activity.getResources().getDrawable(R.drawable.round_online);
         drawableOffline = activity.getResources().getDrawable(R.drawable.round_offline);
    }

    @Override
    public int getCount() {
        return mData.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(final int pPosition, View pView, ViewGroup pParent) {
        pView = mInflater.inflate(R.layout.list_stat, null,false);

        String name = mData.get(pPosition).getName();
        String first = name.substring(0, 1);

        TextView txtCount = pView.findViewById(R.id.txt_count);

        txtCount.setText(first);

        TextView txtName = pView.findViewById(R.id.txt_name);
        txtName.setText(name);
        TextView txtNumber = pView.findViewById(R.id.txt_number);
        txtNumber.setText("Number: "+mData.get(pPosition).getNumber());

        int onlineBg = ResourcesCompat.getColor(mActivity.getResources(), R.color.onlineBg, null);
        int offlineBg = ResourcesCompat.getColor(mActivity.getResources(), R.color.offlineBg, null);
        int white = ResourcesCompat.getColor(mActivity.getResources(), R.color.colorWhite, null);
        int black = ResourcesCompat.getColor(mActivity.getResources(), R.color.colorBlack, null);


        ImageView btnGetCSV = pView.findViewById(R.id.btnGetCSV);
        ImageView btnNotificationOff = pView.findViewById(R.id.btnNotificationOff);
        ImageView btnNotificationOn = pView.findViewById(R.id.btnNotificationOn);
        ImageView btnNumberDetails = pView.findViewById(R.id.btnNumberDetails);
        ImageView btnRemoveNumber = pView.findViewById(R.id.btnRemoveNumber);

        btnGetCSV.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                onMenuItemClickListener.onGetCSVClick();
            }
        });
        btnNotificationOff.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                onMenuItemClickListener.onNotificationOffClick();
            }
        });
        btnNotificationOn.setOnClickListener(new View.OnClickListener() {
            @Override
