Android Composite(ListView)詳解

1.ListView概述

2.ListView使用中的重要角色(Adapter,ViewHolder,資料集,布局)

3.ListView常用屬性

4.ListView+ArrayAdapter

5.ListView+SimpleCursorAdapter

6.ListView+SimpleAdapter

7.ListView+自定義Adapter(繼承BaseAdapter)

8.下拉重新整理,上拉加載(SwipeRefreshLayout(google官方下來重新整理元件)+自定義上拉加載更多)

1.ListView概述

見名知意，ListView即為顯示list集合的一個view控件，當然他不可能直接與資料适配顯示，她們之間需要adapter這個橋梁來适配

2.ListView使用中的重要角色(Adapter,ViewHolder,資料集,布局)

Adapter：即為資料與布局提供橋梁進行适配，常見的Adapter有：ArrayAdapter，SimpleCursorAdapter，SimpleAdapter

抽象的BaseAdapter。

ViewHolder：ViewHolder模式其實非常優秀，他在其中扮演着優化ListView加載的效率角色（怎樣優化，代碼見，說起來總沒那麼容易了解）

資料集：資料當然就不用說，就是需要顯示在使用者界面的一個集合，可以是圖檔+文字或者隻有文字。

布局：就是整個ListView控件和單條資料的顯示樣式布局，換句話說就是定義你的單個資料應該如何顯示。

3.ListView常用屬性

android:choiceMode="multipleChoice|none|multipleChoiceModal|singleChoice":設定清單項選擇模式，單選，多選或者預設的無法選擇
    android:fastScrollEnabled="true":設定是否開啟快速滾動條
    android:fastScrollAlwaysVisible="true":設定是否總是顯示快速滾動條
    android:scrollbars="horizontal|vertical|none":設定滾動條，豎直，水準，無
    android:stackFromBottom="true|false":設定是否從底部開始顯示
    android:transcriptMode="alwaysScroll|normal|disabled":設定ListView在增加新項時是否自動滑動到底部
    android:divider="":設定item之間的分割（圖檔，顔色，@null都可以）
    android:fadingEdgeLength="":設定item陰影
    android:listSelector="":設定清單選中項的背景圖檔
    android:drawSelectorOnTop="true|false":設定選中項的背景是否顯示在選擇内容之上

4.ListView+ArrayAdapter

4.1)主java類MainActivity.java

package com.example.listview;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private ArrayList<String> list;
    private ArrayAdapter<String> arrayAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //初始化布局
        listView = (ListView) findViewById(R.id.first_lv);
        //設定不滑動時是否顯示滑動條，true表示當滑動時顯示，不滑動時不顯示，false一直顯示
        //listView.setScrollbarFadingEnabled(false);
        //設定垂直ScrollBar是否開啟，不開啟在滑動的時候不顯示ScrollBar
        listView.setVerticalScrollBarEnabled(false);
        //初始化資料
        list = new ArrayList<String>();
        for (int i= 1;i<20;i++){
            list.add("資料"+i);
        }
        //初始化擴充卡
        //Context：表示目前context及MainActivity.this
        // int resource:單條資料顯示布局
        // List<T> objects：ArrayList資料集合
        arrayAdapter = new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,list);
        //設定擴充卡
        listView.setAdapter(arrayAdapter);
    }

}

        //執行個體化内容接收者

        simpleCursorAdapter = new SimpleCursorAdapter(this,R.layout.simple_cursor_item,

7.ListView+自定義Adapter(繼承BaseAdapter)

ps:有時候我們不僅僅是顯示資料，可能會在單個item中添加一些控件并實作控件的相關操作，比如添加：button,checkbox等

7.1)自定義Adapter類CustomAdapter.java

package com.example.listview;

    * Context：指執行個體化CustomAdapter的上下文
    * ArrayList：表示需要适配的資料源
    * */

Android Composite(ListView)詳解

8.下拉重新整理,上拉加載(SwipeRefreshLayout(google官方下來重新整理元件)+自定義上拉加載更多)

8.1)自定義ListView類PullRefreshListView.java

package com.example.listview;

import android.content.Context;
import android.support.v4.widget.SwipeRefreshLayout;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.widget.AbsListView;
import android.widget.ListView;

/**
 * Created by elimy on 2016-08-29.
 */
public class PullRefreshListView extends ListView implements AbsListView.OnScrollListener{

    //底部加載更多的控件
    private View footerView;
    //底部重新整理高度
    private int footerHeight;
    //辨別是否滑動到底部
    private boolean isScrollToBottom = false;
    //辨別是否正在加載
    private boolean isRefreshing = false;
    //對ListView的下拉和上拉重新整理進行監聽的變量
    private OnRefreshListener myOnRefreshListener;

    /*
    帶一個參數的構造函數
    * */
    public PullRefreshListView(Context context) {
        super(context);
    }
    /*
    * 帶兩個參數的構造函數
    * */
    public PullRefreshListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        //通過View.inflate()初始化自定義的底部重新整理View
            footerView = View.inflate(getContext(),R.layout.footer_view,null);
            Log.d("footer_view",footerView.toString()+"");
        //測繪footerView
        if (footerView != null){
            footerView.measure(0,0);
            //擷取底部控件高度并初始化
            footerHeight = footerView.getMeasuredHeight();
            //剛開始隐藏footerView
            footerView.setPadding(0, -footerHeight, 0, 0);
            //添加footerView到ListView
            this.addFooterView(footerView);
            //為初始化的PullRefreshListView設定監聽
            this.setOnScrollListener(this);
        }else {
            Log.d("footerView_debug","footerView is null");
        }

    }
    /*
    * 開放監聽器接口，友善在使用的時候為自定義的PullRefreshListView添加監聽并實作監聽後的操作
    * */
    public void setOnRefreshListener(OnRefreshListener onRefreshListener){
        myOnRefreshListener =onRefreshListener;
    }
    /*
    * 實作隐藏方法，提供給使用的類在加載完後隐藏footerView
    * */
    public void hideFooterView (){
        footerView.setPadding(0, -footerHeight, 0, 0);
        isRefreshing=false;
    }
    /*
    *scroll狀态改變的監聽，繼承至AbsListView.OnScrollListener
    * */
    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {
        if (scrollState == SCROLL_STATE_FLING || scrollState == SCROLL_STATE_IDLE){
            if (!isRefreshing && isScrollToBottom){
              isRefreshing = true;
                //顯示出footerView
                footerView.setPadding(0,0,0,0);
                //設定選中可見item的最後一項
                this.setSelection(this.getCount());
                if (myOnRefreshListener != null){
                    myOnRefreshListener.refreshData();
                }
            }
        }
    }
    /*
    * 對ListView正在滾動進行監聽
    * */
    @Override
    public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
        int endItemPosition =totalItemCount-1;
        if (endItemPosition==getLastVisiblePosition()){
            isScrollToBottom =true;
        }else {
            isScrollToBottom = false;
        }
    }
    /*
    * 自定義一個接口供外界調用實作上拉重新整理資料
    * */
    public interface OnRefreshListener{
        void refreshData();
    }
}

8.2)底部重新整理view xml布局footer_view.xml

<?xml version="1.0" encoding="utf-8"?>

    </RelativeLayout>

8.4)主布局檔案refresh_listview.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

      </com.example.listview.PullRefreshListView>
    </android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>

8.5)資料構造類ListItems.java

package com.example.listview;

import java.util.ArrayList;

/**

 */
public class ListItems {
    public ArrayList<String> getBottomRefreshData(){
       ArrayList<String> list = new ArrayList<String>();
        for (int i = 1;i<=5;i++){
            list.add("上拉重新整理資料"+i);
        }
        return list;
    }
    public ArrayList<String> getFirstData(){
        ArrayList<String> list = new ArrayList<String>();
        for (int i = 1;i<=5;i++){
            list.add("初始資料"+i);
        }
        return list;
    }
    public ArrayList<String> getStartData(){
        ArrayList<String> list = new ArrayList<String>();
        for (int i = 1;i<=5;i++){
            list.add("下拉重新整理資料"+i);
        }
        return list;
    }
