从Android联系人中检索照片和姓名

Question

目前我的代码只能获取联系人的电话号码。但是我想要获取 联系人的姓名和联系人的照片路径。尝试了很多谷歌搜索到的代码，但是我无法完成它。也尝试了这个，但是遇到了FileNotFoundException。请问有人可以通过添加代码片段来帮助我实现吗?

public void getContact(View view)
{

         Intent intent = new Intent(Intent.ACTION_PICK);
         intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE);
         startActivityForResult(intent, 1); 

}

protected void onActivityResult(int requestCode, int resultCode,Intent data)
    {
        super.onActivityResult(requestCode, resultCode, data);

             if(resultCode==RESULT_OK && requestCode == 1)
        {
            if (data != null) {
                Uri uri = data.getData();

                if (uri != null) {
                    Cursor c = null;
                    try {
                        c = getContentResolver().query(uri, new String[]{ 
                                    ContactsContract.CommonDataKinds.Phone.NUMBER,  
                                    ContactsContract.CommonDataKinds.Phone.TYPE },
                                null, null, null);

                        if (c != null && c.moveToFirst()) {
                            String phoneNumber = c.getString(0);
                            int type = c.getInt(1);      
                        }
                    } finally {
                        if (c != null) {
                            c.close();
                        }
                    }
                }
            }
        }
         }

这段代码遍历所有联系人并获取他们的名字、姓氏和照片（以位图形式）：

Cursor cursor = App
            .getInstance()
            .getContentResolver()
            .query(ContactsContract.Contacts.CONTENT_URI, null, null, null,
                    null);

    if (cursor != null && cursor.getCount() > 0) {
        while (cursor.moveToNext()) {
            long id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Contacts._ID));

            // get firstName & lastName
            Cursor nameCur = App.getInstance().getContentResolver()
                    .query(ContactsContract.Data.CONTENT_URI,
                            null,
                            ContactsContract.Data.MIMETYPE
                                    + " = ? AND "
                                    + StructuredName.CONTACT_ID
                                    + " = ?",
                            new String[] {
                                    StructuredName.CONTENT_ITEM_TYPE,
                                    Long.valueOf(id).toString() }, null);
            if (nameCur != null) {
                if (nameCur.moveToFirst()) {

                    String displayName = nameCur.getString(nameCur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                    if (displayName == null) displayName = "";

                    String firstName  = nameCur.getString(nameCur.getColumnIndex(StructuredName.GIVEN_NAME));
                    if (firstName == null) firstName = "";
                    Log.d("--> ", firstName.length()>0?firstName:displayName);

                    String middleName = nameCur.getString(nameCur.getColumnIndex(StructuredName.MIDDLE_NAME));
                    if (middleName == null) middleName = "";

                    String lastName = nameCur.getString(nameCur.getColumnIndex(StructuredName.FAMILY_NAME));
                    if (lastName == null) lastName = "";

                    lastName = middleName + (middleName.length()>0?" ":"") + lastName;

                    Log.d("--> ", lastName);
                }
                nameCur.close();
            }

            Bitmap photo = null;

            try {
                InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(App.getContext().getContentResolver(),
                        ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long.valueOf(id)));

                if (inputStream != null) {
                    photo = BitmapFactory.decodeStream(inputStream);
                }

                if (inputStream != null) inputStream.close();

            } catch (IOException e) {
                e.printStackTrace();
            }

            Log.d("--> ", photo);
        }
    }

    if (cursor != null) { cursor.close(); }

您还需要这个权限：<uses-permission android:name="android.permission.READ_CONTACTS" />

希望有所帮助！

这是我从 Fragment 中获取联系人照片、号码和姓名的方法。

1 在你的清单文件中设置权限。

<uses-permission android:name="android.permission.READ_CONTACTS" />

2 声明一个常量：

private static final int REQUEST_CODE_PICK_CONTACT = 1;

3 在我的应用程序中，用户需要通过点击按钮选择电话联系人。因此，在onClick()方法中，我这样做：

contactChooserButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivityForResult(new Intent(Intent.ACTION_PICK,
          ContactsContract.Contacts.CONTENT_URI), REQUEST_CODE_PICK_CONTACT);

        }
    });

4 添加获取照片、姓名和号码的方法：

private String retrieveContactNumber() {

    String contactNumber = null;

    // getting contacts ID
    Cursor cursorID = getActivity().getContentResolver().query(uriContact,
            new String[]{ContactsContract.Contacts._ID},
            null, null, null);

    if (cursorID.moveToFirst()) {

        contactID = cursorID.getString(cursorID.getColumnIndex(ContactsContract.Contacts._ID));
    }

    cursorID.close();

    Log.e(TAG, "Contact ID: " + contactID);

    // Using the contact ID now we will get contact phone number
    Cursor cursorPhone = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},

            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " +
                    ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
                    ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,

            new String[]{contactID},
            null);

    if (cursorPhone.moveToFirst()) {
        contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
        phoneNumber = contactNumber;
    }

    cursorPhone.close();

    Log.e(TAG, "Contact Phone Number: " + contactNumber);
    return contactNumber;

}

 //Retrieve name
 private void retrieveContactName() {

    String contactName = null;

    // querying contact data store
    Cursor cursor = getActivity().getContentResolver().query(uriContact, null, null, null, null);

    if (cursor.moveToFirst()) {

        // DISPLAY_NAME = The display name for the contact.
        // HAS_PHONE_NUMBER =   An indicator of whether this contact has at least one phone number.

        contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
        personName = contactName;
    }

    cursor.close();

    Log.e(TAG, "Contact Name: " + contactName);

}

//Retrieve photo (this method gets a large photo, for thumbnail follow the link below)
public void retrieveContactPhoto() {

    Uri contactUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long.parseLong(contactID));
    Uri displayPhotoUri = Uri.withAppendedPath(contactUri, ContactsContract.Contacts.Photo.DISPLAY_PHOTO);
    try {
        AssetFileDescriptor fd =
                getActivity().getContentResolver().openAssetFileDescriptor(displayPhotoUri, "r");
        photoAsBitmap = BitmapFactory.decodeStream(fd.createInputStream());

    } catch (IOException e) {
        e.printStackTrace();
    }
}

最后，在你的onActivityForResult方法中，做这个：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);        
    try {

        if(requestCode == REQUEST_CODE_PICK_CONTACT && resultCode == Activity.RESULT_OK) {
            Log.e(TAG, "Response: " + data.toString());
            uriContact = data.getData();
            personPhoneTextField.setText(retrieveContactNumber()); 
//the method retrieveContactNumber returns the contact number, 
//so am displaying this number in my EditText after getting it.
//Make your other methods return data of 
//their respective types (Bitmap for photo)

  retrieveContactPhoto();
  retrieveContactName();


        }
    } catch (Exception exception) {
        exception.printStackTrace();

    }
}

就这样了。关于活动，请查看Github上的Android：获取联系人详细信息（ID、姓名、电话、照片）。
