Introduction
Basically string values stored/updated into array/base adapter for using set into listview.but this project is different because while search some name means its index values are changing during its position values so need to set some more adapter for storing filter values for other purpose(move index values into another activity,toast purpose etc...)
demo
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="wrap_content"
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>
list_items.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"/>
</LinearLayout>
