暑假第五十三天，好多天没有更新博客了，貌似这十多天都在一直在关注这奥运会的赛事，现在奥运会结束了，自己也该学习了，看看最近实现的通讯录吧，能实现简单的增加联系人、删除联系人、设置私密账号、点击item可以对该联系人进行通话、调用系统的拨号界面、备份数据、恢复数据简单的功能！然后呢，接着咱就可以看看实现的过程
首先先看一下布局
1。欢迎界面的布局startimage.xml
<?xml version="1.0" encoding="utf-8"?><ImageView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/startimage" android:layout_width="fill_parent" android:layout_height="fill_parent" android:clickable="true" android:src="@drawable/welcome" ></ImageView>
2.接着是主界面main.xml
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/bg" > <FrameLayout android:id="@+id/list_ll" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ListView android:id="@+id/lv_userlist" android:layout_above="@+id/gv_buttom_menu" android:layout_width="fill_parent" android:layout_height="wrap_content"/> <!-- <TextView android:id="@+id/tvLetter" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:background="@drawable/textviewbg" android:gravity="center" android:maxWidth="50dp" android:minWidth="50dp" android:textColor="#FF6100" android:textSize="50sp" /> <com.wang.A_Z.ListA_Z android:id="@+id/myView" android:layout_width="30dip" android:layout_height="fill_parent" android:layout_gravity="right" /> --> </FrameLayout> <GridView android:id="@+id/gv_buttom_menu" android:layout_height="80dp" android:layout_width="fill_parent" android:layout_alignParentBottom="true" android:visibility="gone"> </GridView> <LinearLayout android:id="@+id/ll_search" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_alignParentLeft="true" android:layout_above="@+id/gv_buttom_menu" android:visibility="gone"> <EditText android:id="@+id/et_search" android:layout_width="fill_parent" android:layout_height="wrap_content" android:hint="请输入查询的号码或姓名" android:textSize="18dp"> </EditText> </LinearLayout></RelativeLayout>3.接着呢，就是增加联系人的界面布局addnewcontacts.xml

7.然后是在点击menu键后，点击item_menu上的监听事件查找电话号码的numchoose.xml 的布局
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/widget28" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/tv_numchoose" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:text="请选择一个号码" android:textSize="17sp" android:typeface="serif" > </TextView> <ListView android:id="@+id/num_list" android:layout_width="fill_parent" android:layout_height="wrap_content" > </ListView></LinearLayout>
8.接着是在点击menu键后，点击item_menu上的监听事件管理通讯录的监听事件main_menu_grid.xml的布局
<?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" ><GridView android:id="@+id/gridview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:numColumns="2" android:verticalSpacing="10dip" android:horizontalSpacing="10dip" android:stretchMode="columnWidth" android:gravity="center" /> </LinearLayout>9.接着是在点击menu键后，点击item_menu上的监听事件管理备份文件夹的名称enterfilename.xml的布局
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/widget29" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/tv_enter_file_name" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="请输入备份文件的文件名\n该文件该置于SD卡的根目录zpContact文件夹下" > </TextView> <EditText android:id="@+id/et_enter_file_name" android:layout_width="fill_parent" android:layout_height="wrap_content" > </EditText></LinearLayout>
10.接着是一个备份时候进度条的布局backup_progress.xml的布局
