ListView和各種Adapter的使用

http://gundumw100.iteye.com/blog/875967

1，和最簡單的ArrayAdapter的使用：

Java代碼

package com.wt.app;

import android.app.ListActivity;

import android.os.Bundle;

import android.widget.ArrayAdapter;

import android.widget.ListAdapter;

public class App extends ListActivity
{

String[] array={/*"aaa","bbb","ccc"*/};

/** Called when the activity is first created.
*/

@Override

public void onCreate(Bundle
savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

//爲空時的顯示內容

this.getListView().setEmptyView(findViewById(R.id.empty));

ListAdapter adapter=new ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,array);

this.setListAdapter(adapter);

}

}

[java]view
plaincopy

package com.wt.app;  

import android.app.ListActivity;  

import android.os.Bundle;  

import android.widget.ArrayAdapter;  

import android.widget.ListAdapter;  

public class App extends ListActivity {  

    String[] array={/*"aaa","bbb","ccc"*/};  

    /** Called when the activity is first created. */  

    @Override  

    public void onCreate(Bundle savedInstanceState) {  

        super.onCreate(savedInstanceState);  

        setContentView(R.layout.main);  

        //爲空時的顯示內容  

        this.getListView().setEmptyView(findViewById(R.id.empty));  

        ListAdapter adapter=new ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,array);  

        this.setListAdapter(adapter);  

    }  

}

Xml代碼  

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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

>

<ListView

android:id="@+id/android:list"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

/>

<TextView

android:id="@+id/empty"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:gravity="center_vertical"

android:text="Nothing"

/>

</LinearLayout>

[xml]view

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

    android:layout_height="fill_parent"  

    >  

<ListView   

    android:id="@+id/android:list"  

    android:layout_width="fill_parent"

2，和SimpleAdapter的使用：

Java代碼  

package com.wt.app;

import android.widget.AdapterView.OnItemClickListener;

public class App extends Activity
{

@Override

public void onCreate(Bundle
savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

//綁定Layout裏面的ListView

ListView list = (ListView) findViewById(R.id.ListView01);

//生成動態數組，加入數據

ArrayList<HashMap<String, Object>> listItem = new ArrayList<HashMap<String,
Object>>();

int[]
images=new int[]{android.R.drawable.ic_menu_add,android.R.drawable.ic_menu_delete,android.R.drawable.ic_menu_edit,android.R.drawable.ic_menu_view};

for(int i=0;i<4;i++)

{

HashMap<String, Object> map = new HashMap<String,
Object>();

map.put("itemImage",
images[i]);//圖像資源的ID

map.put("itemTitle", "Title
"+i);

map.put("itemText", "this
is Text "+i);

listItem.add(map);

}

//生成適配器的Item和動態數組對應的元素

SimpleAdapter listItemAdapter = new SimpleAdapter(this,listItem,//數據源

R.layout.row,//ListItem的XML實現

//動態數組與ImageItem對應的子項

new String[]
{"itemImage","itemTitle", "itemText"},

//ImageItem的XML文件裏面的一個ImageView,兩個TextView ID

new int[]
{R.id.itemImage,R.id.itemTitle,R.id.itemText}

);

//添加並且顯示

list.setAdapter(listItemAdapter);

//添加點擊

list.setOnItemClickListener(new OnItemClickListener()
{

public void onItemClick(AdapterView<?>
arg0, View arg1, int arg2,

long arg3)
{

setTitle("點擊第"+arg2+"個項目");

}

});

//添加長按點擊

list.setOnCreateContextMenuListener(new OnCreateContextMenuListener()
{

public void onCreateContextMenu(ContextMenu
menu, View v,ContextMenuInfo menuInfo) {

menu.setHeaderTitle("長按菜單-ContextMenu");

menu.add(0, 0, 0, "彈出長按菜單0");

menu.add(0, 1, 0, "彈出長按菜單1");

}

});

}

//長按菜單響應函數

@Override

public boolean onContextItemSelected(MenuItem
item) {

setTitle("點擊了長按菜單裏面的第"+item.getItemId()+"個項目");

return super.onContextItemSelected(item);

}

}

[java]view
