Custom listview





As the simple ListView, custom ListView also uses Adapter classes which added the content from data source (such as string array, array, database etc). Adapter bridges data between an AdapterViews and other Views

 Clu List Xml code:

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:dividerHeight="10dp"
    android:divider="@android:color/transparent"

    android:padding="16dp"
    android:id="@+id/list"
    android:orientation="vertical"

Variables

Variables The main way to store information in the middle of a PHP program is by using a variable. Here are the most important things to know about variables in PHP. All variables in PHP are denoted with a leading dollar sign ($). The value of a variable is the value of its most recent assignment. Variables are assigned with the = operator, with the variable on the left-hand side and the expression to be evaluated on the right. Variables can, but do not need, to be declared before assignment. Variables in PHP do not have intrinsic types - a variable does not know in advance whether it will be used to store a number or a string of characters. Variables used before they are assigned have default values. PHP does a good job of automatically converting types from one to another when necessary. PHP variables are Perl-like. PHP has a total of eight data types which we use to construct our variables − Integers  − are whole numbers, without a decima...

SQL Server - INTERSECT Operator

Description The SQL Server (Transact-SQL) INTERSECT operator is used to return the records that are in common between two SELECT statements or data sets. If a record exists in one query and not in the other, it will be omitted from the INTERSECT results. It is the intersection of the two SELECT statements. Intersect Query Explanation:  The INTERSECT query will return the records in the blue shaded area. These are the records that exist in both Dataset1 and Dataset2. Each SELECT statement within the SQL Server INTERSECT must have the same number of columns in the result sets with similar data types. Syntax The syntax for the NTERSECT operator in SQL Server (Transact-SQL) is: SELECT expression1, expression2, ... expression_n FROM tables [WHERE conditions] INTERSECT SELECT expression1, expression2, ... expression_n FROM tables [WHERE conditions]; Parameters or Arguments expressions The columns or calculations that you wish to compare between the two SELECT ...
