Android簡單的ListViewDemo及每個控制項的點擊事件，listview控制項點擊事件

 

main.xml首頁面布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:gravity="center">    <ListView        android:id="@+id/lv"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        /></LinearLayout>

list_item.xml每個item的排布

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="60dp"    android:orientation="horizontal">    <LinearLayout        android:layout_width="60dp"        android:layout_height="60dp">        <ImageView            android:id="@+id/image"            android:layout_width="fill_parent"            android:layout_height="fill_parent"/>    </LinearLayout>    <LinearLayout        android:layout_width="fill_parent"        android:layout_height="60dp"        android:orientation="vertical"        android:gravity="center">        <TextView            android:id="@+id/title"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:textSize="25sp"/>        <TextView            android:id="@+id/context"            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:textSize="15sp"/>    </LinearLayout></LinearLayout>
