【中文标题】获取联系人照片【英文标题】：Getting Photos of contacts 【发布时间】：2014-01-14 21:49:21 【问题描述】：我正在努力通过光标获取联系人。一切正常，但显示联系人照片并没有返回任何内容。我没有遇到任何崩溃或错误。我的代码是
ContactListActivity.java
Cursor cur= getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null,null);
list.setAdapter(new contactAdapter(getApplicationContext(), cur));
我自定义创建的光标适配器是
class contactAdapter extends CursorAdapter
String Name, phoneNumber;
private Cursor cursor;
private Context ccontext;
private LayoutInflater inflater;
public contactAdapter(Context context, Cursor c)
super(context, c);
// TODO Auto-generated constructor stub
cursor = c;
ccontext = context;
inflater = LayoutInflater.from(context);
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
@SuppressLint("InlinedApi")
@SuppressWarnings("deprecation")
@Override
public void bindView(View view, Context arg1, Cursor arg2)
// TODO Auto-generated method stub
ViewHolder holder = (ViewHolder) view.getTag();
if (holder == null)
holder = new ViewHolder();
holder.contactsImage = (ImageView) view.findViewById(R.id.contact_image);
holder.ContactName = (TextView) view.findViewById(R.id.contact_name);
holder.contactCheck = (CheckBox) view.findViewById(R.id.contact_check);
view.setTag(holder);
holder.contactCheck.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
// TODO Auto-generated method stub
cb = (CheckBox) v;
cb.setChecked(cb.isChecked());
// ContactPerson selected = (ContactPerson)cb.getTag();
Log.d("selcted", cb.getTag().toString());
if(cb.isChecked())
phoneID.add(cb.getTag().toString());
);
else
holder = (ViewHolder) view.getTag();
// Uri uri = ContentUris.withAppendedId(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, cursor.getLong(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID)));
// Log.d("ImagePath", ContactsContract.CommonDataKinds.Phone.PHOTO_FILE_ID);
if(cursor.getString(cursor.getColumnIndex("mimetype")).equals(ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE))
byte[] photoByte = cursor.getBlob(cursor.getColumnIndex("data15"));
if(photoByte != null)
Bitmap bitmap = BitmapFactory.decodeByteArray(photoByte, 0, photoByte.length);
// Getting Caching directory
File cacheDirectory = getBaseContext().getCacheDir();
// Temporary file to store the contact image
File tmpFile = new File(cacheDirectory.getPath() + "/wpta_"+cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_ID))+".png");
// The FileOutputStream to the temporary file
try
FileOutputStream fOutStream = new FileOutputStream(tmpFile);
// Writing the bitmap to the temporary file as png file
bitmap.compress(Bitmap.CompressFormat.PNG,100, fOutStream);
// Flush the FileOutputStream
fOutStream.flush();
//Close the FileOutputStream
fOutStream.close();
holder.contactsImage.setImageBitmap(bitmap);
catch (Exception e)
e.printStackTrace();
String photoPath = tmpFile.getPath();
Log.d("photoPath", photoPath);
// holder.contactsImage.setImageBitmap(bitmap);
holder.ContactName.setText(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
holder.contactCheck.setTag(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID)));
holder.contactCheck.setChecked(false);
@Override
public View newView(Context arg0, Cursor arg1, ViewGroup arg2)
// TODO Auto-generated method stub
return inflater.inflate(R.layout.checkbox_item, arg2, false);
@Override
public View getView(int arg0, View arg1, ViewGroup arg2)
// TODO Auto-generated method stub
// Log.d("don't know", cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
return super.getView(arg0, arg1, arg2);
谁能告诉我哪里出错并指导我获取照片。我到处搜索并实现了代码。但它们都没有产生所需的结果。
【问题讨论】：
【参考方案1】：这是您可以从联系人 URI 获取图像的代码。
String image_uri = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI));
bitmap = MediaStore.Images.Media .getBitmap(this.getContentResolver(), Uri.parse(image_uri));
contactpic.setImageBitmap(bitmap) ;
【讨论】：
它显示为“12-27 15:39:26.387: E/CursorWindow(21442): Bad request for field slot 0,-1. numRows = 100, numColumns = 63”【参考方案2】：试试这个代码
private void getContactsDetails()
Cursor phones = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, null);
while (phones.moveToNext())
String Name = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String Number = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String image_uri = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
System.out.println("Contact1 : " + Name + ", Number " + Number
+ ", image_uri " + image_uri);
if (image_uri != null)
image.setImageURI(Uri.parse(image_uri));
【讨论】：
【参考方案3】：尝试以下方法获取联系人姓名和联系人照片。
private void retrieveContactPhoto()
Bitmap photo = null;
try
InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(),
ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(contactID)));
if (inputStream != null)
photo = BitmapFactory.decodeStream(inputStream);
ImageView imageView = (ImageView) findViewById(R.id.imageView1);
imageView.setImageBitmap(photo);
assert inputStream != null;
inputStream.close();
catch (IOException e)
e.printStackTrace();
/**
* super fast query to pull email addresses. It is much faster than pulling
* all contact columns as suggested by other answers...
*
* @return
*/
public ArrayList<ContactVo> getNameEmailDetails()
ArrayList<ContactVo> m_arrList = new ArrayList<ContactVo>();
ArrayList<String> emlRecs = new ArrayList<String>();
HashSet<String> emlRecsHS = new HashSet<String>();
ContentResolver cr = m_context.getContentResolver();
String[] PROJECTION = new String[] ContactsContract.RawContacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_ID,
ContactsContract.CommonDataKinds.Email.DATA,
ContactsContract.CommonDataKinds.Photo.CONTACT_ID ;
String order = "CASE WHEN " + ContactsContract.Contacts.DISPLAY_NAME
+ " NOT LIKE '%@%' THEN 1 ELSE 2 END, "
+ ContactsContract.Contacts.DISPLAY_NAME + ", "
+ ContactsContract.CommonDataKinds.Email.DATA
+ " COLLATE NOCASE";
String filter = ContactsContract.CommonDataKinds.Email.DATA
+ " NOT LIKE ''";
Cursor cur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI, PROJECTION,
filter, null, order);
ContactVo m_vo;
if (cur.moveToFirst())
do
m_vo = new ContactVo();
// names comes in hand sometimes
String name = cur.getString(1);
String emlAddr = cur.getString(3);
System.err.println("Value Is---------->" + cur.getString(2)
+ "Name--" + name + "Email---" + emlAddr);
m_vo.setM_sName(name);
m_vo.setM_sEmail(emlAddr);
// keep unique only
if (emlRecsHS.add(emlAddr.toLowerCase()))
emlRecs.add(emlAddr);
m_arrList.add(m_vo);
while (cur.moveToNext());
cur.close();
return m_arrList;
