Getting the TextView from the adapter of listview in android

What I have: I have text View in every row of a list view

What I am trying to do:

CODE::

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listviewdemo);

        final ListView listviewone = (ListView) findViewById(R.id.listviewone);
        listviewone.setAdapter(mAdapterOne);

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

                Log.d("", "");                  

            }
        });
    }

XML-of adapter

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#fff"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/title"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:textColor="#000" />

    <ImageView
        android:id="@+id/image"
        android:layout_width="150dp"
        android:layout_height="150dp"
        android:scaleType="centerCrop"
        android:padding="5dp"
        android:src="@drawable/img" />

     <ImageView
        android:id="@+id/imageLine"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/line" />



</LinearLayout>

Use a interface for click event on that TextView

Code snippet

interface to handle click event

public interface ListItemBtnClickInterface {

    public void listItemBtnClickListener(Object obj, int viewId, String value);
}

I'm using ArrayAdapter

code for Constructor of Adapter 

public AddExpTypeAdapter(Context context, int resource,
        List<ExpenseTypeInfo> objects, ListItemBtnClickInterface _interface) {
    super(context, resource, objects);
    // TODO Auto-generated constructor stub
    _context = context;
    layoutId = resource;
    dataList = objects;
    this._interface = _interface;
    notifyDataSetChanged();
}

code for TextView's click in Adapter after initialization and setting Text

vieweHolder.urView.setTag(position);
vieweHolder.urView.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Object data = v.getTag();
            if(data != null) {
                String value = vieweHolder.urView.getText().toString();
                _interface.listItemBtnClickListener(data, v.getId(), value);
            }
        }
    });

code for Setting up adapter of ListView in Activity

addExpTypeAdapter = new AddExpTypeAdapter(AddExpTypeActivity.this, 
            R.layout.row_add_type, expTypeList, new ListItemBtnClickInterface() {

                private int clickedPosition;

                @Override
                public void listItemBtnClickListener(Object obj, int viewId, String value) {
                        // TODO Auto-generated method stub
                        clickedPosition = Integer.parseInt(obj.toString());

                        switch (viewId) {
                        case R.id.urView:
                            Log.d("Clicked TextView's Value ===> " , value);
                            break;

                        default:
                            break;
                        }
                    }
                });
        typeListView.setAdapter(addExpTypeAdapter);

If you want the value set on textview then try it this way.. 

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

               TextView mText  = (TextView) view
                    .findViewById(R.id.title);      

               String value= mText.getText().ToString().trim();            

            }
        });

try like this, 

 private String getName(int pos){
                View view = listviewone.getAdapter().getView(pos, null, listviewone);
                TextView name = (TextView) view.findViewById(R.id.title);

                return name.getText().ToString();
    }

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

                    Log.d("NAME", getName(position));                  

                }
            });

hope it will help you

((TextView) view.findViewById(R.id.title).getText().toString()

However I would suggest you to get the text from the adapter itself, since the adapter will be used to populate the ListView.

view is the list item, so you can do

String str =(String) ((TextView) view.findViewById(R.id.txt)).getText();

Get name at particular list item from ListView data holder :

Example :

ArrayList<HashMap<String,String>> listData= new ArrayList<HashMap<String, String>>();
HashMap<String,String> row1=  new HashMap<String, String>();
row1.put("name","AAA");
listData.add(row1);

listviewone.setOnItemClickListener(new AdapterView.OnItemClickListener() {
     @Override
     public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
          Log.d("Name :", listData.get(position).get("name"));                  
     }
});

Note : listData use for ListView data holder which is pass adapter to build ListView item.
