How To Add A Custom Dialog With Listview And Search Function In Android Fragment

I want to create exactly same view shown below, I used showDialog function to display dialog. private void showDialog() { FragmentTransaction ft = getFragmentManager().beginT

Solution 1:

    final Dialog dialog_data = newDialog(context);

    dialog_data.requestWindowFeature(Window.FEATURE_NO_TITLE);

    dialog_data.getWindow().setGravity(Gravity.CENTER);

    dialog_data.setContentView(R.layout.custom_alertdialog);

    WindowManager.LayoutParams lp_number_picker = newWindowManager.LayoutParams();
    Windowwindow = dialog_data.getWindow();
    lp_number_picker.copyFrom(window.getAttributes());

    lp_number_picker.width = WindowManager.LayoutParams.MATCH_PARENT;
    lp_number_picker.height = WindowManager.LayoutParams.WRAP_CONTENT;

    window.setGravity(Gravity.CENTER);
    window.setAttributes(lp_number_picker);

    TextView alertdialog_textview = (TextView) dialog_data.findViewById(R.id.alertdialog_textview);
    alertdialog_textview.setText(selected_string);
    alertdialog_textview.setHint(selected_string);

    Button dialog_cancel_btn = (Button) dialog_data.findViewById(R.id.dialog_cancel_btn);
    dialog_cancel_btn.setOnClickListener(newView.OnClickListener()
    {
        @OverridepublicvoidonClick(View v)
        {
            if(dialog_data != null)
            {
                dialog_data.dismiss();
                dialog_data.cancel();
            }

        }
    });

    EditText filterText = (EditText) dialog_data.findViewById(R.id.alertdialog_edittext);
    ListView alertdialog_Listview = (ListView) dialog_data.findViewById(R.id.alertdialog_Listview);
    alertdialog_Listview.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    final ArrayAdapter<String>  adapter = newArrayAdapter<>(context, android.R.layout.simple_list_item_single_choice, array_data);
    alertdialog_Listview.setAdapter(adapter);
    alertdialog_Listview.setOnItemClickListener(newAdapterView.OnItemClickListener()
    {
        @OverridepublicvoidonItemClick(AdapterView<?> a, View v, int position, long id)
        {
            Utility.hideKeyboard(context,v);


 //data.setText(String.valueOf(a.getItemAtPosition(position)));if(dialog_data != null)
            {
                dialog_data.dismiss();
                dialog_data.cancel();
            }
        }
    });

    filterText.addTextChangedListener(newTextWatcher()
    {
        @OverridepublicvoidbeforeTextChanged(CharSequence s, int start, int count, int after)
        {

        }

        @OverridepublicvoidonTextChanged(CharSequence s, int start, int before, int count)
        {

        }

        @OverridepublicvoidafterTextChanged(Editable s)
        {
            adapter.getFilter().filter(s);
        }
    });

    dialog_data.show();

Solution 2:

Just replace this line with new one

older one---> final Dialog dialog_data = new Dialog(context);

New one---> final Dialog dialog_data = new Dialog(getActivity());
