How to select item in the list view programmatically

I have an ArrayList<String> List which contains some items from the listview all_list. How can I select these items in the list view all_list programmatically by checking the ArrayList<String> List contents?
for e.g., listview all_list contains [0] apple
[1] orange
[2] banana
In ArrayList<String> List, I have orange so I want item on position 1 on the listview all_list to be selected (highlighted) automatically.
I have tried using all_list.setItemChecked(), but it does nothing and shuts down the application. I am performing the operation after listing the adapter.

set an onItemClickListener to the listview such that on click, you set a boolean flag that sets the checkbox in each row to selected. then call notifyDataSetChanged()

Try this
MainActivity.java
package com.example.multiseekbar;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
public class MainActivity extends Activity {
ListView listView1;
ArrayList<ModelClass> modelClass = new ArrayList<ModelClass>();
FruitSelectAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
modelClass.add(new ModelClass("Orange", true));
modelClass.add(new ModelClass("Apple", false));
modelClass.add(new ModelClass("Banana", false));
modelClass.add(new ModelClass("Grapes", false));
listView1 = (ListView) findViewById(R.id.listView1);
adapter = new FruitSelectAdapter(MainActivity.this, modelClass);
listView1.setAdapter(adapter);
listView1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
if(modelClass.get(arg2).isSelected()){
modelClass.get(arg2).setSelected(false);
}else{
modelClass.get(arg2).setSelected(true);
}
adapter.notifyDataSetChanged();
}
});
}
}

How to get row position for the ListView when a button on the row pressed [duplicate]

how to get a list item position by clicking the button inside it?

I have a simple list with 3 items including a button. I want to get the row number of the button. I am not able to get it work. Experts please help.

lv.setOnItemClickListener(this);
String[] countries = new MyCountries().getCountries();
ListAdapter la = new MyListAdapter(this, countries);
lv.setAdapter(la);
}
#Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.list_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will

return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(this, "Clicked Position " + String.valueOf(position), Toast.LENGTH_SHORT).show();
}
public void onClick(View v)
{
View myView = v;
}
}

String [] locales = Locale.getISOCountries();
countries = new String[locales.length];
for (int i = 0; i < locales.length; i ++) {
Locale obj = new Locale("", locales[i]);
countries[i] = obj.getDisplayCountry();
} return countries;
}

}
}
My list adapter
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.content.Context;
import android.widget.ImageView;
import android.widget.TextView;
public class MyListAdapter extends ArrayAdapter <String> {
private final Context context;
private final String[] values;
public MyListAdapter(Context context, String[] values) {
super(context, R.layout.list_row, values);
this.context = context;
this.values = values;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_row, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.editText);
textView.setText(values[position]);
textView = (TextView) rowView.findViewById(R.id.textView);
textView.setText(values[position]);
return rowView;
}
}
I need to get the position either in onItemClick() or onClick()
Thanks in advance.
Adding OnClickListener() for each button while inflating would be overkill as I will have hundreds of rows.

I modified my onClick() to include
ListView lv = (ListView) findViewById(R.id.listView);
final int position = lv.getPositionForView((LinearLayout)v.getParent());
Got the hint from this post - how to get a list item position by clicking the button inside it?

Add a button click listener to your button when creating your views
public MyListAdapter(Context context, String[] values) {
super(context, R.layout.list_row, values);
this.context = context;
this.values = values;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.list_row, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.editText);
textView.setText(values[position]);
textView = (TextView) rowView.findViewById(R.id.textView);
textView.setText(values[position]);
***button = (Button) rowView.findViewById(R.id.button);
button.setOnClickListener(new OnClickListener(){})***
return rowView;
}

I can't find any errors or notice something irregular, so why is that happening?

you should extend BaseAdapter and implement abstract methods
#Override
public int getCount() {
return web.size();
}
#Override
public Object getItem(int position) {
return web.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
also you might change
txtTitle.setText((CharSequence) web.get(position));
to
txtTitle.setText((CharSequence) getItem(position));
now your adapter don't know size of web array
edit:
you can get one inflater in constructor and keep in class, no need to getting inflater each time (little bit better for perfomance)
LayoutInflater inflater = context.getLayoutInflater();
edit 2:
localhost put proper comment - you are removing all Views from RelativeLayout, also ListView, and creating new ListView without adding to Relative. keeping reference will not auto-add View
protected void onPostExecute(Object result) {
layout = (RelativeLayout) getView().findViewById(R.id.blogPage);
layout.removeView(getView().findViewById(R.id.txtLabel);
//assuming you need to remove only txtLabel
CustomList adapter = new CustomList(getActivity(), titles);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getActivity(),
"You Clicked at " + titles.get(position),
Toast.LENGTH_SHORT).show();
}
});
}

I m trying to make an listview that is empty in the starting of the application.in which a textview will give information to tab on icon..,and when user tab and create an app.the data shown in the listview..bt listview is giving an error ,how to solve it..

case R.id.nextPage:
Intent i = new Intent(this,SmsSend.class);

break;
}
return super.onOptionsItemSelected(item);
}
}

UPDATE:
You have done everything wrong. you need to change as follows.
public Demo(Context context, String[] values) {
super(context, R.layout.activity_list_demostration);
this.context = context;
this.values = values;
}
to
public Demo(Context context, String[] values) {
super(context, values);
this.context = context;
this.values = values;
}
In Campaign_Details Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_demostration);
ListView listview = (ListView) findViewById(R.id.listView1);
TextView emptyText = (TextView)findViewById(android.R.id.empty);
According to your question finally you need to change here from
ListView listview = (ListView) findViewById(R.id.listView1);
to
ListView listview = (ListView) findViewById(R.id.listView);

public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
return inflater.inflate(R.layout.custom_show_action_bar, null);
}
}
}
