Issue while using contextmenu with listview items in a popupwindow

I am developing an android application, my proposal is have two clickable textviews on the page and when user press each of the textview, a listview in a popupwindow will shows under the textview, when user choose a listview item, the textview will be setText() as the name as user selected, when user perform long click on the textview or on the listview item, a contextmenu can be shown to allow user "edit"(jump to a new activity for that) or "delete" the selected item and after that the list adapter can update the list accordingly.
I have finished the code of registerContextMenu for the textview and it works, but the context menu won't show after I added the same code to the listview, I also tried add OnCreateContextMenuListener to the listview but failed again. can any expert help to look into this? thanks a lot.

How to fetch data from a custom list view with multiple radio buttons

I have gone through a lot of links here, but yet i was not able to get my stuff working. Can you please help me fetch data from my custom list.
Details are as under :- My custom list view
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RadioGroup
android:id="#+id/radioGroup_option"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/tv_id"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:focusable="false"/>
<RadioButton
android:id="#+id/rb_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<RadioButton
android:id="#+id/rb_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RadioGroup>
</LinearLayout>
I am populating a List through the UI the code for that is :-
package com.example.customadapter;
import java.lang.reflect.Array;
import java.util.Arrays;
import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class CustomAdapter extends ActionBarActivity {
AddDataToArray mydata;
EditText qstno,qstn,opt1,opt2;
Button btn_save,btn_display;
int questio_no;
String question,option1,option2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom_adapter);
mydata=AddDataToArray.getInstance();
qstno=(EditText)findViewById(R.id.edt_qstn_no);
qstn=(EditText)findViewById(R.id.edt_add_qstn);
opt1=(EditText)findViewById(R.id.edt_opt1);
opt2=(EditText)findViewById(R.id.edt_opt2);
btn_save=(Button)findViewById(R.id.btn_save);
btn_display=(Button)findViewById(R.id.btn_display);
btn_save.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
questio_no=Integer.parseInt(qstno.getText().toString());
question=qstn.getText().toString();
option1=opt1.getText().toString();
option2=opt2.getText().toString();
System.out.println("Questio added in the UI --> "+ question);
String statusReceived=mydata.AddingQuestions(questio_no, question, option1, option2);
Toast.makeText(getApplicationContext(), statusReceived, Toast.LENGTH_LONG).show();
qstn.setText("");
opt1.setText("");
opt2.setText("");
}
});
btn_display.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
for (int i=0;i<mydata.myQstnList.size();i++)
{
System.out.println("Qustion no"+mydata.myQstnList.get(i).getQstno());
System.out.println("Question -->"+mydata.myQstnList.get(i).getQstn());
//System.out.println("The First Option added was:-" + mydata.myQstnList.get(i).getOpt1());
}
Intent myIntent = new Intent(CustomAdapter.this, Mediator.class);
startActivity(myIntent);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.custom_adapter, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Finally i made an adapter from base adapter as follows:-
package com.example.customadapter;
import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;
import android.widget.Toast;
public class MyAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private List<Question> mQuestion;
Context context;
public MyAdapter(Context context,List<Question> mQuestion) {
super();
this.context=context;
this.mQuestion = mQuestion;
this.mInflater = LayoutInflater.from(context);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return mQuestion.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return mQuestion.get(position);
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View view;
ViewHolder holder;
if (convertView == null){
view = mInflater.inflate(R.layout.customized_view, parent,false);
holder = new ViewHolder();
holder.rg=(RadioGroup)view.findViewById(R.id.radioGroup_option);
holder.tv_qstn=(TextView)view.findViewById(R.id.tv_id);
holder.rb_opt1=(RadioButton)view.findViewById(R.id.rb_1);
holder.rb_opt2=(RadioButton)view.findViewById(R.id.rb_2);
view.setTag(mQuestion);
}else {
view = convertView;
holder = (ViewHolder)view.getTag();
}
Question qstnRef=mQuestion.get(position);
holder.tv_qstn.setText(qstnRef.getQstn());
holder.rb_opt1.setText(qstnRef.getOpt1());
holder.rb_opt2.setText(qstnRef.getOpt2());
holder.rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
//List<Question> data =(List<Question>) group.getTag();
//Toast.makeText(context,(CharSequence) data.get(checkedId).getOpt2(),Toast.LENGTH_SHORT).show();
int childCount=group.getChildCount();
for (int i=0;i<childCount;i++){
RadioButton r_btn=(RadioButton)group.getChildAt(i);
if (r_btn.getId() == checkedId){
System.out.println(r_btn.getText().toString());
}
}
}
});
return view;
}
private class ViewHolder {
public TextView tv_qstn;
public RadioButton rb_opt1,rb_opt2;
public RadioGroup rg;
}
}
But i am trying to get this data that i enter in the UI, but I am not able to get this to work, please provide me assistance !!!!
The code in the current format is giving me runtime error :-
05-09 06:01:06.669: E/AndroidRuntime(2420):
java.lang.ClassCastException: android.widget.TextView cannot be cast
to android.widget.RadioButton
05-09 06:01:06.669: E/AndroidRuntime(2420): at
com.example.customadapter.MyAdapter$1.onCheckedChanged(MyAdapter.java:83)

group.getChildCount() returns 3 as it has 3 child. but 1 child is of TextView that's why you were getting java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.RadioButton
To avoid it do type checking using instanceof before typecasting.
do like this:
int childCount=group.getChildCount();
for (int i=0;i<childCount;i++){
if(group.getChildAt(i) instanceof RadioButton ) { // check if child is `RadioButton`
RadioButton r_btn = (RadioButton) group.getChildAt(i);
if (r_btn.getId() == checkedId) {
System.out.println(r_btn.getText().toString());
}
}
}

Now the layout file for this is list_note.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.96"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/ViewTitleNotes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_margin="20dp"
android:textColor="#000000"
android:textStyle="bold"
android:focusable="false"
android:focusableInTouchMode="false"
/>
</RelativeLayout>
</LinearLayout>
</LinearLayout>
When I implement above code every thing works fine. However, I want to include some other data so i am calling another layout file which includes additional data:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/mainText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Pinned Questions" />
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/mainText"
android:background="#FFFFFF"
/>
<TextView
android:id="#android:id/empty"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/mainText"
android:text="There is no data"
android:textStyle="bold" />
</RelativeLayout>
When I include this layout the list shows up but nothing happens when I click on list item. The normal working would be when I click list item it should open the next activity with desired clicked item.
Thanks in advance.

Well I would suggest You To Implement View.OnItemClickListener() and then use
noteListView.setOnItemClickListener(this);
This will work perfectly.
Hope I Helped.

Use a ListView, and assign a 9-patch drawable to each item's background which will consist of a centered dot and the vertical line.
The whole trick will be to specify the strechable regions of your nine-patch properly (stretch the line and not the dot).
Once you are happy with that, just make a different dot appearance for the active element and use an XML selector drawable to assign either the default or activated state 9 patch to the background.
