How to make only the list title visible in the list menu and not the entire content of the list item in listview android studio?

I'm trying to make a simple note-taking app. I tried to display the notes in the listview. But when I add more content to the note it displays the entire content in the main menu of the list view. How to make only the title of the list visible in the Listview and the content visible only when we open the list item?

Sorry, about the former one, I didn't explain properly using another format use two edittext one for title and one for the body.Save them in different preferences using the body key as the title
Pass the title preference to the listview.

Android Listview Search filter

I am trying to make a list view search for Android. I have found many tutorials that do just that where
a search-bar is placed at the top and if you type in the box the results get filtered.
In my app I want to click on given items after filtering has been completed, I have implemented setOnItemClickListener. The issue is that after filtering the position of each class that I want to open changes and the incorrect pages open. I was unable to find a solution....
Here is the jave code:
package com.equations.search;
import java.util.ArrayList;
import java.util.HashMap;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.TextView;
public class EquationsSearch extends Activity {
// List view
private ListView lv;
// Listview Adapter
ArrayAdapter<String> adapter;
// Search EditText
EditText inputSearch;
// ArrayList for Listview
ArrayList<HashMap<String, String>> productList;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.equations_search);
// Listview Data
final String products[] = { "Dell Inspiron", "HTC One X",
"HTC Wildfire S", "HTC Sense", "HTC Sensation XE" };
lv = (ListView) findViewById(R.id.list_view);
inputSearch = (EditText) findViewById(R.id.inputSearch);
// Adding items to listview
adapter = new ArrayAdapter<String>(this,
R.layout.equations_search_list, R.id.product_name, products);
lv.setAdapter(adapter);
/**
* Enabling Search Filter
* */
inputSearch.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence cs, int arg1, int arg2,
int arg3) {
// When user changed the Text
EquationsSearch.this.adapter.getFilter().filter(cs);
}
public void beforeTextChanged(CharSequence arg0, int arg1,
int arg2, int arg3) {
// TODO Auto-generated method stub
}
public void afterTextChange(Editable arg0) {
// TODO Auto-generated method stub
}
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// if(position == 1)
String openClass = products[position];
if (openClass.equals("HTC Wildfire S")) {
// code specific to first list item
Intent myIntent = new Intent(view.getContext(), A6262.class);
startActivityForResult(myIntent, 0);
}
}
});
}
}
and here is the xml equations_search.xml

Thank you in advance.

Rather than products[position], use adapter.getItem(position). When the ListView is not in filter mode, those two things will be the same. But, in filter mode, getItem() will take the filtering into account.

The ListAdapter will change the relative position of the items it currently shows due to the filtering. You should always use getItem(position) to retrieve the correct item.

Send ListView results via Messaging application

I am very new to programming. I have an app that has several views. The Main view shows a list such as Breakfast, Lunch & Dinner. When a an item is selected, example Lunch, a list of lunch menu items is displayed such as Hamburger, Cheeseburger, French Fries... (this list is created from the string-array lunch_menu that is stored in \values\lunch.xml) as the user selects the items they want, it is stored in a new array called myNewList and is displayed whe the users presses the lunchList button. All of the items are displayed that the user selected. So far, So good. I created a android:onClick="shareMyList" in the selecteditems.xml and the button works, but does not populate my list. I think what i need is to some how convert it to a string, this is where I need help.
Here is my Problem now.... I have my Share button, that when pressed, I would like it to automatically open the default Messaging app and populate the list from the selected items ListView.

This may be the most kludgiest way of doing this, but it works.

Android 2.2 requestFocus() and spinners

I'm having problems using s.requestFocus() when s is a spinner. Is there a special treatment to get it to work when it's a spinner ?
Thanks

try this code..
spinner.setFocusable(true);
spinner.setFocusableInTouchMode(true);

I'm guessing you aren't literally just looking to "give focus" to the spinner. When you give focus to an EditText, the keyboard pops up, so you may be expecting the spinner selection to "open up" on focus - but it doesn't work that way (don't ask me why). Use s.performClick() to do this - it will act just as if the user clicked on the spinner control.

Spinner isn't focusable by default (source). So you have to make it focusable either in xml
<Spinner
android:id="#+id/spinner"
android:focusable="true"
android:layout_width="wrap_conten"
android:layout_height="wrap_content" />
or in code
findViewById(R.id.spinner).setFocusable(true);
