Listview delete item | Delete Row Item in ListView | Delete a row from list view on button click in android

Hello friends,

Today i am going to post very important post which used in daily development of application.
I will be having list, on press of edit button an alert dialog box will pop out asking you for confirmation with having Yes and Cancel Button. Lets start using coding...

Step 1: Create main.xml :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linear_popup"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/darker_gray"
        android:padding="5dp" >

        <Button
            android:id="@+id/btnClearAll"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:background="@drawable/btn_blue"
            android:padding="5dp"
            android:text="Clear all"
            android:textColor="@android:color/white"
            android:textSize="12sp"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btnEdit"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:background="@drawable/btn_blue"
            android:padding="5dp"
            android:text="Edit"
            android:textColor="@android:color/white"
            android:textSize="12sp"
            android:textStyle="bold" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:text="Delete List item"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textColor="@android:color/white"
            android:textStyle="bold" />
    </RelativeLayout>

    <ListView
        android:id="@+id/lstviewitems"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="2dp"
        android:cacheColorHint="@android:color/transparent"
        android:divider="@drawable/menu_seprator"
        android:dividerHeight="1dp"
        android:fadingEdge="none"
        android:fastScrollEnabled="true"
        android:scrollingCache="false" >
    </ListView>

    <TextView
        android:id="@+id/txtNoFound"
        android:layout_width="fill_parent"
        android:layout_height="80dp"
        android:gravity="center"
        android:text="No data found"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textColor="@android:color/black"
        android:visibility="gone" />

</LinearLayout>

Step 2: Create row_item.xml :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical" >

    <ImageButton
        android:id="@+id/imgbtnDelete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:background="@android:color/transparent"
        android:contentDescription="@string/app_name"
        android:src="@drawable/ic_delete" />

    <TextView
        android:id="@+id/txtTitle"
        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_marginBottom="3dp"
        android:layout_weight="1"
        android:paddingBottom="12dp"
        android:paddingLeft="5dp"
        android:paddingRight="5dp"
        android:paddingTop="12dp"
        android:singleLine="true"
        android:text="@string/app_name"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:textColor="@android:color/black" />

</LinearLayout>

Step 3: Item Class:

public class Item 
{
 public String Title;

 public String getTitle() 
 {
  return Title;
 }

 public void setTitle(String title) 
 {
  Title = title;
 }
 
}

Step 4: MainActivity.class
