最近使用到联系人查找的功能并直接拨号,查看自己之前写的代码,感觉着实麻烦。还是觉得整理成博客比较好，于是就整理了一下。

一,获取全部联系人并装到集合中
①联系人工具类

/** * 获取联系人信息 */public class ContactsEngine {    /**     * 获取系统的联系人信息     */    public static List<ContactsInfo> getAllContacts(Context context){        List<ContactsInfo> list = new ArrayList<ContactsInfo>();        //获取内容解析者        ContentResolver contentResolver = context.getContentResolver();    Uriuri=ContactsContract.CommonDataKinds.Phone.CONTENT_URI;        String[] projection = new String[]{            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,            ContactsContract.CommonDataKinds.Phone.NUMBER,            ContactsContract.CommonDataKinds.Phone.CONTACT_ID        };        Cursor cursor = contentResolver.query(uri, projection, null, null, null);        //解析cursor获取数据        while(cursor.moveToNext()){            String name = cursor.getString(0);            String number = cursor.getString(1);            int contactId = cursor.getInt(2);            ContactsInfo contactsInfo = new ContactsInfo(name, number, contactId);            list.add(contactsInfo);        }        return list;    }    /**     * 根据联系人的id,获取联系人的头像     */    public static Bitmap getContactPhoto(Context context,int contactid){        ContentResolver contentResolver = context.getContentResolver();        Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, contactid+"");        //获取联系人的头像,以流的形式返回        InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(contentResolver, uri);        //将流转化成bitmap        Bitmap bitmap = BitmapFactory.decodeStream(inputStream);        //关流        if (inputStream != null) {            try {                inputStream.close();            } catch (IOException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }        }        return bitmap;    }

②联系人信息Javabean

/** * 联系人的bean * */public class ContactsInfo {    public String name;    public String number;    public int id;    public ContactsInfo(String name, String number, int id) {        super();        this.name = name;        this.number = number;        this.id = id;    }}

二,根据联系人查找电话号码直接拨打号码

  /**     *根据名字拨打电话     */    public void nameNumberCall(String name) {        Cursor cursor = mContext.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);        while (cursor.moveToNext()) {            String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));            String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));            if (name.equals(contactName)) {                Cursor phone = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null);                if (phone.moveToNext()) {                    String phoneNumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));                    Intent intentPhone = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + phoneNumber));                    if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {                        mContext.startActivity(intentPhone);                        return;                    }                    break;                }            }else {    //TODO 根据姓名没有查找到联系人给用户做一个友好提示            }        }    }

根据电话查找联系人

 /**     * 根据电话查找姓名     */    public String numberToName(String num) {        Intent intentPhone = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + num));        mView.setIntent(intentPhone);        String displayName = null;        Cursor cursor = null;        try {            ContentResolver resolver = mContext.getContentResolver();            Uri uri = ContactsContract.PhoneLookup.CONTENT_FILTER_URI.buildUpon().appendPath(num).build();            String[] projection = new String[]{COLUMN_ID, COLUMN_DISPLAY_NAME};            cursor = resolver.query(uri, projection, null, null, null);            if (cursor != null && cursor.moveToFirst()) {                int columnIndexName = cursor.getColumnIndex(COLUMN_DISPLAY_NAME);                displayName = cursor.getString(columnIndexName);            }        } catch (Exception e) {            e.printStackTrace();        } finally {            if (cursor != null) {                cursor.close();            }        }        return displayName;    }
