android 通讯录的实现
通讯录，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"

4.接着是图片选择的对话框界面的imageswitch.xml的布局
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/widget34"
android:layout_width="fill_parent"

android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="25px"
android:orientation="horizontal" >
<TextView
android:id="@+id/tv_showname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="top"
android:text="姓名:"
android:textColor="#000000"
android:textSize="17sp" />
<TextView
android:id="@+id/tv_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="7"
android:gravity="left"
android:textColor="#000000"
android:textSize="17sp" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="25px"
android:orientation="horizontal" >
<TextView
android:id="@+id/tv_showmobilephone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"

android:textSize="20sp" />
</LinearLayout>
</LinearLayout>
<ImageView
android:id="@+id/user_mark"
android:layout_width="60px"
android:layout_height="15px"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="@drawable/checkmark"
android:visibility="gone" />
</RelativeLayout><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/item_image"
android:layout_centerHorizontal="true" >
</TextView>
</RelativeLayout>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:gravity="center"
/>
</LinearLayout>
<?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
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/widget29"

style="?android:attr/progressBarStyleHorizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ProgressBar>
<Button
android:id="@+id/btn_backuup_ok"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="OK"
android:visibility="gone" >
</Button>
</LinearLayout>11.接着呢就是5s钟的欢迎界面 startAnimation.java
package com.wang.Activity;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;
import android.view.View.OnClickListener;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.widget.ImageView;
public class startAnimation extends Activity {
ImageView startimage;
AlphaAnimation startAnimation;
protected void onCreate(Bundle savedInstanceState) {
// 去除标题
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
// 取消状态栏，充满全屏
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.startimage);
startimage = (ImageView) findViewById(R.id.startimage);
// 设置动画的渐变效果逐渐增强
startAnimation = new AlphaAnimation(0.0f, 1.0f);
// 设置动画显示的时间为3s
startAnimation.setDuration(5000);
// 开始动画效果
startimage.startAnimation(startAnimation);
// 为动画效果设置监听事件
startAnimation.setAnimationListener(new AnimationListener() {
// ka开始
@Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
// 重复
@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
// 动画结束
@Override
public void onAnimationEnd(Animation animation) {
// 声明一个意图，启动一个新的Activity
Intent intent = new Intent(startAnimation.this,
AddressPhoneBookDemoActivity.class);
// 启动新的Activity
startActivity(intent);
}
});
// 当点击图片的时候也可以进行跳转
startimage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(startAnimation.this,
AddressPhoneBookDemoActivity.class);
// 启动新的Activity
startActivity(intent);
}
});
}
}
12.然后就是跳转到主界面实现过程AddressPhoneBookDemoActivity.java

public String email;
public String otherContact;
public String remark;
public int imageId;
public int privacy;//1代表隐私用户 0代表普通用户
}
16.亲，最后别忘了添加权限和注册Activity哦！！
<?xml version="1.0" encoding="utf-8"?>

</manifest>解释一下，第一张的欢迎界面， 第二张是跳转的的主界面 第三张的点击item拨打联系人电话的界面
第四张的增加联系人的界面 第五张的选择联系人头像的界面 第六张是查找联系人的界面
第七张是删除一条已标记的联系人的界面 第八张是管理联系人的界面 第九张的删除所有联系人的界面
第十张是调用系统拨号功能的界面 第十一张是备份数据的界面 第十二章是备份完成的界面
