如何将 listview 适配器项目点击侦听器转到 android 中的片段？

Question

我想从 listview adapter itemview click listener 转到带有额外详细信息的 fragment，我想在我去的那个 fragment 中使用它们。我使用这个 list view adapter class.I 想从 listview adapter itemview click listener to fragment with extra details that I want to use in that fragment where I go..我使用这个列表视图适配器class。

public class ListViewAdapter extends BaseAdapter {

    // Declare Variables
    Context context;
    LayoutInflater inflater;
    ArrayList<HashMap<String, String>> data;

    HashMap<String, String> resultp = new HashMap<String, String>();
    public ListViewAdapter(Context context, ArrayList<HashMap<String, String>> arraylist) {
        this.context = context;
        data = arraylist;
    }
  @Override
    public int getCount() {
        return data.size();
    }

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

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

    public View getView(final int position, View convertView, ViewGroup parent) {
        // Declare Variables
        TextView ip;
        TextView port;

        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View itemView = inflater.inflate(R.layout.listview_item, parent, false);
        // Get the position
        resultp = data.get(position);

        // Locate the TextViews in listview_item.xml
        ip = (TextView) itemView.findViewById(R.id.ip);
        port = (TextView) itemView.findViewById(R.id.port);

        // Locate the ImageView in listview_item.xml

        // Capture position and set results to the TextViews
        ip.setText(resultp.get(AddFragment.ip));
        port.setText(resultp.get(AddFragment.port));
        // Capture position and set results to the ImageView
        // Passes flag images URL into ImageLoader.class
        // Capture ListView item click
        itemView.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // Get the position
                resultp = data.get(position);
                Intent intent = new Intent(context, MainActivity.class);
                // Pass all data rank
                intent.putExtra("ip", resultp.get(AddFragment.ip));
                // Pass all data country
                intent.putExtra("port", resultp.get(AddFragment.port));
                intent.putExtra("uname", resultp.get(AddFragment.uname));
                intent.putExtra("password", resultp.get(AddFragment.password));

                Log.e("uname: ", "> " + resultp.get(AddFragment.uname));
                Log.e("password: ", "> " + resultp.get(AddFragment.password));
                Log.e("ip: ", "> " + resultp.get(AddFragment.ip));
                Log.e("port: ", "> " + resultp.get(AddFragment.port));



                // Pass all data population
                // Pass all data flag
                // Start SingleItemView Class
                context.startActivity(intent);

            }
        });
        return itemView;
    }

所以我怎样才能去片段而不是 activity。我想把这个放在片段中，把额外的细节放在一起。那么，我该怎么走？

Answer 1

试试这个

((Activity) mContext).getFragmentManager();

 itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Fragment fragment = new CallThisFragment();
            FragmentManager fragmentManager = ((Activity) mContext).getFragmentManager();
            fragmentManager.beginTransaction().replace(R.id.main_activity, fragment).commit();
        }
    });

并使用 bundle 将数据传递给片段 class How to pass Bundle from Fragment to Fragment

Answer 2

使用下面的代码去片段中的列表视图适配器项目点击监听器

relaylist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int
    position, long id) {


            HashMap<String, String> o = (HashMap<String, String>)
    relaylist.getItemAtPosition(position);



            Log.e("ip: ", "> " +  o.get("ip"));
            Log.e("port: ", "> " +  o.get("port"));
            Log.e("uname: ", "> " +  o.get("uname"));
            Log.e("password: ", "> " +  o.get("password"));


            ControlFragment fragment = new ControlFragment();

            FragmentTransaction transaction =
    getFragmentManager().beginTransaction();


            Log.e("ip: ", "> " +  o.get("ip"));
            Log.e("port: ", "> " +  o.get("port"));
            Log.e("uname: ", "> " +  o.get("uname"));
            Log.e("password: ", "> " +  o.get("password"));
            transaction.replace(R.id.mainFrame, fragment );
            Bundle bundle = new Bundle();
            bundle.putString("ip", o.get("ip"));
            bundle.putString("port", o.get("port"));
            bundle.putString("uname", o.get("uname"));
            bundle.putString("password", o.get("password"));
            fragment.setArguments(bundle);
            transaction.commit();
        }
    });
