Custom Listview with search bar also passing string[] and image values to another activity

Introduction 

In my previous post , we implemented a Custom listview with search bar .

Now,we'll see how to implement a search function with string array and image values passing from one activity to another activity.The default text filter associated with theListView. For now,we'll see how we can search the ListView with passing values.

Using the code

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout 

    android:id="@+id/LinearLayout01"

    android:layout_width="fill_parent"

android:layout_height="fill_parent"

    xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="vertical">

    

<EditText 

    android:id="@+id/EditText01"

android:layout_height="40dp"

android:layout_width="fill_parent"

android:hint="search"/>

 <ListView android:id="@+id/android:list"

    android:cacheColorHint="#00000000"

android:layout_width="fill_parent"

android:layout_height="wrap_content"/>

</LinearLayout>

search_list_item.xml:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:orientation="horizontal"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:padding="8dp">

<TextView

android:id="@+id/title"

android:textColor="#000"

    android:layout_width="0dp"

    android:layout_weight="1"

    android:layout_margin="10dp"

    android:layout_height="wrap_content"/>

    

<ImageView 

    android:id="@+id/imageview"

    android:layout_width="30dp"

    android:layout_height="30dp"

    android:src="@drawable/ic_launcher"

    android:layout_marginRight="10dp"

    android:contentDescription="@string/app_name"/>

</LinearLayout>
