專案技術：利用 ListView + SimpleAdapter 將 name 和 number 顯示出來，

  通過給 item 設定監聽（setOnItemClickListener）土司“ name 和 number ”

專案描述：通過 ListView+SimpleAdapter 將 name+ number 顯示出來，並且 還需要在點選每一項時 土司“name 和 number ” 

        在每項顯示多種資料的時候 我們可以使用 HashMap 來存放資料

實現如下圖：

activity_main.xml

<RelativeLayoutxmlns:android

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context=".MainActivity">

<ListView

android:id="@+id/lv_contacts"

android:layout_width="match_parent"

android:layout_height="wrap_content"

       />

</RelativeLayout>

contact_item.xml

<?xmlversion="1.0"encoding="utf-8"?>

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

android:layout_width="match_parent"

android:padding="10dp"

android:layout_height="match_parent">

<TextView

android:id="@+id/tv_contact_item_name"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:textSize="16sp"

android:layout_marginBottom="5dp"

android:textColor="#000000"

        android:text="yyl"/>

<TextView

android:id="@+id/tv_contact_item_number"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_below="@+id/tv_contact_item_name"

android:textSize="14sp"

android:textColor="#555555"

android:text="100000000"/>

</RelativeLayout>

 實體類，用於描述資料的屬性

Contact.java

package cn.sophia.android_listview_simpleadapter;

public class Contact {

private String name;

private String number;

public Contact(String name, String number) {

super();

this.name = name;

this.number = number;

}

public String getName() {

returnname;

}

public void setName(String name) {

this.name = name;

}

public String getNumber() {

returnnumber;

}

public void setNumber(String number) {

this.number = number;

}

}

// 為控制元件設定監聽

listView.setOnItemClickListener(new OnItemClickListener() {

@Override

Toast.makeText(MainActivity.this,"name:"+name+"&"+"number:"+number, Toast.LENGTH_SHORT).show();

}

});
