获取手机联系人信息这一十分常用的功能,最近项目里也要实现此功能,想到以后的APP还十分可能还有此功能,就干脆把这个小功能放到一个类中去,这样以后再遇到这个需求就不需要再去写代码了,直接把这个类拷过来就可以用了.

以下是获取联系人demo的效果图,比较简陋,能说明问题就好.

这里写图片描述

在日常Android手机的使用过程中，根据电话号码获得联系人头像，是经常会碰到的问题。本文即以实例形式讲述了Android根据电话号码获得联系人头像是实现代码。分享给大家供大家参考之用。具体方法如下：

首先，通过ContentPRovider，可以访问Android中的联系人等数据。常用的Uri有：

联系人信息Uri：content://com.android.contacts/raw_contacts联系人电话Uri：content://com.android.contacts/data/phones

并且提供了根据电话号码获取data表数据的功能，方法为：data/phones/filter/号码，返回一个数据集。再通过数据集获得该联系人的contact_id，根据contact_id打开头像图片的InputStream，最后用BitmapFactory.decodeStream()获得联系人的头像。

// 根据号码获得联系人头像 public Bitmap get_people_image(String p_number) { Bitmap bmp_head=null; // 获得Uri Uri uriNumber2Contacts = Uri.parse("content://com.android.contacts/" + "data/phones/filter/" + p_number); // 查询Uri，返回数据集 Cursor cursorCantacts = resolver.query( uriNumber2Contacts, null, null, null, null); // 如果该联系人存在 if (cursorCantacts.getCount() > 0) { // 移动到第一条数据 cursorCantacts.moveToFirst(); // 获得该联系人的contact_id Long contactID = cursorCantacts.getLong(cursorCantacts.getColumnIndex("contact_id")); // 获得contact_id的Uri Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, contactID); // 打开头像图片的InputStream InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(resolver, uri); // 从InputStream获得bitmap bmp_head = BitmapFactory.decodeStream(input); } return bmp_head; }

★填充联系人信息（联系人名字、电话、头像）到集合中，以下是关键代码：

private List<Map<String, String>> fillListContent(ContentResolver resolver) { List<Map<String, String>> list = new ArrayList<Map<String, String>>(); // 把没有被删除的数据查出来 : deleted=0 Cursor cursor_raw_Contacts = resolver.query( Uri.parse(uri_raw_contacts), new String[]{"_id", "display_name"}, "deleted=0", null, null); while (cursor_raw_Contacts.moveToNext()) { Map<String, String> map = new HashMap<String, String>(); String contacts_id = cursor_raw_Contacts .getString(cursor_raw_Contacts.getColumnIndex("_id")); String contacts_display_name = cursor_raw_Contacts .getString(cursor_raw_Contacts .getColumnIndex("display_name")); map.put("id", contacts_id); map.put("display_name", contacts_display_name); // 根据raw_contact_id查询data表的phone的信息 , 注意uri路径 Cursor cursor_phones = resolver.query(Uri.parse(uri_data_phones), new String[]{"data1"}, "raw_contact_id=?", new String[]{contacts_id}, null); StringBuilder sb = new StringBuilder(); while (cursor_phones.moveToNext()) { sb.append(cursor_phones.getString(0)).append(" "); } map.put("phones", sb.toString()); cursor_phones.close(); list.add(map); } cursor_raw_Contacts.close(); return list; }

接下来就让我们一步步显示这个效果吧。1.右侧字母索引的导航条这个我们可以在网上找到很多类似的，你大可找一个自己喜欢的甚至自己写一个出来，这里我在网上找了一个带波浪效果的，看起来比较炫酷一点吧。这是原地址：https://github.com/AlexLiuSheng/AnimSideBar然后我把它导入到了我们项目中并修改了部分代码，以下是我项目中的SideBar.java

package com.czb.contacts.sidebar;import android.annotation.TargetApi;import android.content.Context;import android.content.res.TypedArray;import android.graphics.Canvas;import android.graphics.Paint;import android.os.Build;import android.util.AttributeSet;import android.util.Log;import android.view.MotionEvent;import android.widget.TextView;import com.czb.contacts.R;/** * Created by Allen Liu on 2016/5/12. */public class SideBar extends TextView { private String[] letters = new String[]{"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z", "#"}; private Paint textPaint; private Paint bigTextPaint; private Paint scaleTextPaint; private Canvas canvas; private int itemH; private int w; private int h; /** * 普通情况下字体大小 */ float singleTextH; /** * 缩放离原始的宽度 */ private float scaleWidth = dp(100);

init(attrs); } @TargetApi(Build.VERSION_CODES.LOLLipOP) public SideBar(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { super(context, attrs, defStyleAttr, defStyleRes); init(attrs); } public void setDataResource(String[] data){ letters=data; invalidate(); } public void setOnStrSelectCallBack(ISideBarSelectCallBack callBack){ this.callBack=callBack; } /** * 设置字体缩放比例 * @param scale */ public void setScaleTime(int scale){ scaleTime=scale; invalidate(); } /** * 设置缩放字体的个数，即开口大小 * @param scaleItemCount */ public void setScaleItemCount(int scaleItemCount){ this.scaleItemCount=scaleItemCount; invalidate(); } private void init(AttributeSet attrs) { // setPadding(dp(10), 0, dp(10), 0); if(attrs!=null) { TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.SideBar); scaleTime= typedArray.getInteger(R.styleable.SideBar_scaleTime,1); scaleItemCount=typedArray.getInteger(R.styleable.SideBar_scaleItemCount,6); } textPaint = new Paint(Paint.ANTI_ALIAS_FLAG); textPaint.setColor(getCurrentTextColor()); textPaint.setTextSize(getTextSize()); textPaint.setTextAlign(Paint.Align.CENTER); bigTextPaint = new Paint(Paint.ANTI_ALIAS_FLAG); bigTextPaint.setColor(getCurrentTextColor()); bigTextPaint.setTextSize(getTextSize() * (scaleTime+2) ); bigTextPaint.setTextAlign(Paint.Align.CENTER); scaleTextPaint = new Paint(Paint.ANTI_ALIAS_FLAG); scaleTextPaint.setColor(getCurrentTextColor()); scaleTextPaint.setTextSize(getTextSize() * (scaleTime + 1)); scaleTextPaint.setTextAlign(Paint.Align.CENTER); } private int dp(int px) { return DensityUtil.dip2px(getContext(), px); } @Override public boolean onTouchEvent(MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: case MotionEvent.ACTION_MOVE: if(event.getX()>(w-getPaddingRight()-singleTextH-10)) { eventY = event.getY(); invalidate(); return true; }else{ eventY = 0; invalidate(); break; } case MotionEvent.ACTION_CANCEL: eventY = 0; invalidate(); return true; case MotionEvent.ACTION_UP: if(event.getX()>(w-getPaddingRight()-singleTextH-10)) { eventY = 0; invalidate(); return true; }else break; } return super.onTouchEvent(event); } @Override protected void onDraw(Canvas canvas) { this.canvas = canvas; DrawView(eventY); } private void DrawView(float y) { int currentSelectIndex = -1; if (y != 0) { for (int i = 0; i < letters.length; i++) { float currentItemY = itemH * i; float nextItemY = itemH * (i + 1); if (y >= currentItemY && y < nextItemY) { currentSelectIndex = i; if(callBack!=null){ callBack.onSelectStr(currentSelectIndex,letters[i]); } //画大的字母 Paint.FontMetrics fontMetrics = bigTextPaint.getFontMetrics(); float bigTextSize = fontMetrics.descent - fontMetrics.ascent; canvas.drawText(letters[i], w - getPaddingRight() - scaleWidth - bigTextSize, singleTextH + itemH * i, bigTextPaint); } } } drawLetters(y, currentSelectIndex); } private void drawLetters(float y, int index) { //第一次进来没有缩放情况，默认画原图 if (index == -1) { w = getMeasuredWidth(); h = getMeasuredHeight(); itemH = h / letters.length; Paint.FontMetrics fontMetrics = textPaint.getFontMetrics(); singleTextH = fontMetrics.descent - fontMetrics.ascent; for (int i = 0; i < letters.length; i++) { canvas.drawText(letters[i], w - getPaddingRight(), singleTextH + itemH * i, textPaint); } //触摸的时候画缩放图 } else { //遍历所有字母 for (int i = 0; i < letters.length; i++) { //要画的字母的起始Y坐标 float currentItemToDrawY = singleTextH + itemH * i; float centerItemToDrawY; if (index < i) centerItemToDrawY = singleTextH + itemH * (index + scaleItemCount);

float maxRightX = w - getPaddingRight(); //如果大于0，表明在y坐标上方 scaleTextPaint.setTextSize(getTextSize() + getTextSize() * delta); float drawX = maxRightX - scaleWidth * delta; //超出边界直接花在边界上 if (drawX > maxRightX) canvas.drawText(letters[i], maxRightX, singleTextH + itemH * i, textPaint);

j <= scaleItemCount; j++) {// double currentY=singleTextH + itemH * i;// canvas.drawText(letters[i], (float) (p * (currentY - y1) * (currentY - y2)), singleTextH + itemH * i, scaleTextPaint);// }// canvas.restore(); // } } } } public interface ISideBarSelectCallBack { void onSelectStr(int index, String selectStr); }}

然后还有2个自定义的属性

<?xml version="1.0" encoding="utf-8"?><resources> <declare-styleable name="SideBar"> <attr name="scaleTime" format="integer"></attr> <attr name="scaleItemCount" format="integer"></attr> </declare-styleable></resources>

2.汉字转拼音工具类

我们知道，Java中是没有提供接口和方法让我们直接将汉字转成拼音的。这里，可以参见我的另一篇博客：Java/Android中汉字转拼音的两种方法，优劣比较然后在此我选择了使用第三方jar包的方式，因为它体积不大而且更加准确。以下是我的Cn2Spell.java

先进行依赖pinyin4j：compile ‘com.belerweb:pinyin4j:2.5.1’

package com.czb.contacts.util;import net.sourceforge.pinyin4j.PinyinHelper;import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;/** * 汉字转换位汉语拼音，英文字符不变 */public class Cn2Spell { public static StringBuffer sb = new StringBuffer(); /** * 获取汉字字符串的首字母，英文字符不变 * 例如：阿飞→af */ public static String getPinYinHeadChar(String chines) { sb.setLength(0); char[] chars = chines.toCharArray(); HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat(); defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE); defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE); for (int i = 0; i < chars.length; i++) { if (chars[i] > 128) { try { sb.append(PinyinHelper.toHanyuPinyinStringArray(chars[i], defaultFormat)[0].charAt(0)); } catch (Exception e) { e.printStackTrace(); } } else { sb.append(chars[i]); } } return sb.toString(); } /** * 获取汉字字符串的第一个字母 */ public static String getPinYinFirstLetter(String str) { sb.setLength(0); char c = str.charAt(0); String[] pinyinArray = PinyinHelper.toHanyuPinyinStringArray(c); if (pinyinArray != null) { sb.append(pinyinArray[0].charAt(0)); } else { sb.append(c); } return sb.toString(); } /** * 获取汉字字符串的汉语拼音，英文字符不变 */ public static String getPinYin(String chines) { sb.setLength(0); char[] nameChar = chines.toCharArray(); HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat(); defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE); defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE); for (int i = 0; i < nameChar.length; i++) { if (nameChar[i] > 128) { try { sb.append(PinyinHelper.toHanyuPinyinStringArray(nameChar[i], defaultFormat)[0]); } catch (Exception e) { e.printStackTrace(); } } else { sb.append(nameChar[i]); } } return sb.toString(); }}

3.通讯录中的名字可以根据拼音来排序

我们选择实现comparable接口，并重写comparaTo方法。以下是我的ContactsModel.java

package com.czb.contacts.event;import android.graphics.Bitmap;import com.czb.contacts.util.Cn2Spell;/** * Created by Administrator on 2016/5/25. */public class ContactsModel implements Comparable<ContactsModel> { private String displayName; // 姓名 private String phone;//电话号码 private String pinyin; // 姓名对应的拼音 private String firstLetter; // 拼音的首字母 private Bitmap bm_head;//头像 public ContactsModel(String displayName,String phone,Bitmap bm_head) { this.bm_head=bm_head; this.phone=phone; this.displayName = displayName; pinyin = Cn2Spell.getPinYin(displayName); // 根据姓名获取拼音 firstLetter = pinyin.substring(0, 1).toUpperCase(); // 获取拼音首字母并转成大写 if (!firstLetter.matches("[A-Z]")) { // 如果不在A-Z中则默认为“#” firstLetter = "#"; } } public Bitmap getBm_head() { return bm_head; } public String getPhone() { return phone; } public String getDisplayName() { return displayName; } public String getPinyin() { return pinyin; } public String getFirstLetter() { return firstLetter; } @Override public int compareTo(ContactsModel another) { if (firstLetter.equals("#") && !another.getFirstLetter().equals("#")) { return 1; } else if (!firstLetter.equals("#") && another.getFirstLetter().equals("#")){ return -1; } else { return pinyin.compareToIgnoreCase(another.getPinyin()); } }}

原理很简单，就是先根据首字母判断，首字母为“#”都放在最后，都为“#”或者都是字母时才根据拼音来比较排序

4.万事俱备只欠东风，接下来就是组装这些东西了

activity_main.xml布局文件
