Adapter to bind data. Uses convertView for view reuse . Only supports vertical scrolling. Less efficient for large datasets.No built-in animations //ViewHolder pattern is optional // Simple to use //Suitable for small listsExample: ListView listView = findViewById(R.id.
#How List View is differing from Recycler View? Explain with example
-> *ListView is an older Android component used to display a simple vertical list. It has limited performance and customization and manually handles view reuse.
activity_main.xml
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
MainActivity.java
ListView listView = findViewById(R.id.listView);
String[] data = {"Apple", "Banana", "Mango"}
Corrective maintenance, the original maintenance technique, remains widely used today. This approach involves repairing a machine after it fails. Corrective maintenance can be categorized into five main types:
1. Plate and Frame Filter
Definition
A plate and frame filter is a pressure filtration equipment used to separate solids from liquids by passing the slurry through filter cloths placed between plates and frames.
Construction
It consists of alternate plates and frames made of cast iron or stainless steel. Each plate is covered with a filter cloth. The frames provide space for solid (cake) collection. The whole assembly is held tightly in a press with inlet and outlet connections.
Working
The slurry is...
Plate and Frame Filter Press
The plate and frame filter is one of the most common batch filtration devices used in chemical and pharmaceutical processing.
Principle: It works on the principle of surface filtration under pressure. Slurry is pumped into the frames, and the liquid (filtrate) is forced through a filter medium (cloth) covering the plates.
Construction: It consists of a series of alternating plates (with grooved surfaces for drainage) and frames (hollow chambers where the cake...
explain the factorendowment theor of international trade ?
The Factor Endowment Theory, also known as the Heckscher–Ohlin Theory, explains the basis of international trade in terms of differences in factor endowments among countries. According to this theory, countries differ in the availability of factors of production such as land, labour, and capital, and these differences give rise to international trade.
The theory states that a country will export goods that use its abundant factors intensively
Arguments Against Free Trade
Free trade, though beneficial in many ways, has been criticized on several grounds. The main arguments against free trade are as follows:
Infant Industry Argument
New and emerging industries in developing countries cannot compete with well-established foreign industries. Protection through tariffs or quotas is necessary until these industries become strong and efficient.
Unemployment
Free trade may lead to closure of domestic industries that cannot compete with cheaper
Motivation: My project is Healthier Snack Chip Development. The primary motivation for this project stems from the growing global scrutiny regarding the nutritional quality and safety of processed snack foods. While snacking is convenient and popular, traditional snack manufacturing—primarily deep-fat frying—is linked to significant health risks. Furthermore, while "healthy" baked alternatives exist, they often suffer from a "health halo" effect, where reduced fat is compensated for with high
Meaning of Macroeconomics studies the economy as a whole. It deals with national income, total output, employment, inflation and economic growth. It focuses on overall economic performance rather than individual units. Examples include GDP of a country, unemployment rate, inflation rate and overall price level. Micro vs Macro Economics Micro studies individual units of the economy such as a single consumer, firm or price of one product. It focuses on individual demand, supply and market behavior.
