Android开发获取联系人信息&根据姓名查找电话%根据电话查找姓名

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。

/**
* 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;

}

/**

*
*/
public class ContactsInfo {

public String name;
public String number;
public int id;

public ContactsInfo(String name, String number, int id) {
super();
b968

this.name = name;
this.number = number;
this.id = id;
}

}

/**
*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 (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
}
}
}

/**

*/
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 {

Uri uri = ContactsContract.PhoneLookup.CONTENT_FILTER_URI.buildUpon().appendPath(num).build();
String[] projection = new String[]{COLUMN_ID, COLUMN_DISPLAY_NAME};
