adapter

I have a ListView with CheckBox on it. and i am using Custom Adapter to populate the ListView . In my xml file i have a Button at bottom. what i want is let user select number of rows in ListView and when he/she clicked on the Button get the position of the selected items so that i could get the object for particular row for further calculations. Below Snippet does exactly what you want. package com.windrealm.android; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import android.app.Activity; import android.content.Context; import android.os.Bundle; import android

一、 MVC 模式 MVC模式代表Model-View-Controller（模型-视图-控制器）模式。这种模式用于应用程序的分层开发。 l Model（模型）：代表一个存取数据的对象或 JAVA POJO。负责执行程序的核心运算与判断逻辑。通过view获得用户输入的数据，然后根据从数据库查询相关的信息，最后进行运算和判断， 再将得到的结果交给view来显示。 l View（视图）：视图代表模型包含的数据的可视化。 l Controller（控制器）：控制器作用于模型和视图上，是model与view之间的枢纽。它控制数据流向模型对象，并在数据变化时更新视图。它使视图与模型分离开。 二、 Adapter Adapter就是中间的这个Controller的部分。 l BaseAdapter：抽象类，实际开发中我们会继承这个类并且重写相关方法，用得最多的一个Adapter！ l ArrayAdapter：支持泛型操作，最简单的一个Adapter，只能展现一行文字~ l SimpleAdapter：同样具有良好扩展性的一个Adapter，可以自定义多种效果！ l SimpleCursorAdapter：用于显示简单文本类型的listView，一般在数据库那里会用到，不过有点过时， 不推荐使用！ 来源： https://www.cnblogs.com/pomodoro/p/11361901

What is the difference between the Bridge and Adapter patterns? James "Adapter makes things work after they're designed; Bridge makes them work before they are. [GoF, p219]" Effectively, the Adapter pattern is useful when you have existing code, be it third party, or in-house, but out of your control, or otherwise not changeable to quite meet the interface you need it to. For instance, we have a SuperWeaponsArray which can control a fine array of doomsday devices. public class SuperWeaponsArray { /*...*/ public void destroyWorld() { for (Weapon w : armedWeapons) { w.fire(); } } } Great. Except

I want to demonstrate use of Adapter Pattern to my team. I've read many books and articles online. Everyone is citing an example which are useful to understand the concept (Shape, Memory Card, Electronic Adapter etc.), but there is no real case study. Can you please share any case study of Adapter Pattern? p.s. I tried searching existing questions on stackoverflow, but did not find the answer so posting it as a new question. If you know there's already an answer for this, then please redirect. Fuhrmanator Many examples of Adapter are trivial or unrealistic ( Rectangle vs. LegacyRectangle,

I want to know when , where and how adapters are used in the context of Android. The information from Android's developer documentation was insufficient for me and I'd like to get a more detailed analysis. success_anil Well adapters in Android are basically a bridge between the UI components and the data source that fill data into the UI Component For example, Lists (UI Component) get populated by using a list adapter, from a data source array. Prashant_M Let’s assume you want to display a list in your Android app. For this you will use the ListView provided by Android. ListView s don’t

I have an ExpandableListView of items and on list item I have TextView with two buttons to increment or decrements the value in TextView on clicks. The problem occurs every time I try to scroll the list. If I increment one item and then scroll the list the values get mixed (becouse the ListView keeps recycling its views) and I don't know how to fix it. I have tried many soulutions I have found here, so yes this may be a duplicate, but I wasn't able to solve my problem with any method I have found. My ExpandableListAdapter.java import android.content.Context; import android.graphics.Typeface;

I have ListView with custom Adapter which supplies View to ListView in this way: public View getView(int position, View convertView, ViewGroup parent) { RelativeLayout.LayoutParams lineParams; RelativeLayout line=new RelativeLayout(context); TextView tv=new TextView(context); tv.setText("Text in postion="+i); lineParams=new RelativeLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); lineParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT); line.addView(tv, lineParams); lineParams.addRule(RelativeLayout.CENTER_IN_PARENT); //checkbox CheckBox checkBox
