Question

我要打电话簿，我可以访问android的联系表格

Answer 1

//访问联系人照片

public static Bitmap loadContactPhoto(ContentResolver cr, long  id) {
        Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
        InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
        if (input == null) {
            return null;
        }
        return BitmapFactory.decodeStream(input);
}

//将方法调用为

Bitmap bitmap = loadContactPhoto(getContentResolver(), _id);
imageView.setImageBitmap(bitmap);

//获取数字

private void getAllNumbers(long id) {
        //Getting numbers
        Cursor phones = null;
        try {
            phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    new String[]{Phone.NUMBER, Phone.TYPE},
                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id, 
                    null,
                    null);
            if(phones != null) {
                while(phones.moveToNext()){
                    switch(phones.getInt(phones.getColumnIndex(Phone.TYPE))){
                        case Phone.TYPE_MOBILE :
                            mobilePhone = phones.getString(phones.getColumnIndex(Phone.NUMBER));
                            break;
                        case Phone.TYPE_HOME :
                            homePhone = phones.getString(phones.getColumnIndex(Phone.NUMBER));
                            break;
                        case Phone.TYPE_WORK :
                            workPhone = phones.getString(phones.getColumnIndex(Phone.NUMBER));
                            break;
                        case Phone.TYPE_OTHER : // You can store other number also
                    }
                }
            }
        } catch (Exception e) {
            //Handle exception
        } finally {
            if(!phones.isClosed() || phones != null)
                phones.close();
        }
    }

快乐的编码。

我在这里分享完整的代码。你必须改变一点，你可以从电话簿中获取姓名，图像和电话号码。感谢
