android - 无法读取手机通讯录

Question

我正在阅读存储在手机中的联系人并在 ListView 中显示它们。
我的代码如下:

String col[]={ContactsContract.Contacts._ID,ContactsContract.Contacts.DISPLAY_NAME};

    Cursor  cursorNames = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, col, null, null, null);
    intentContactsToreturn=new Intent();

    ArrayList<String> contactNames=new ArrayList<String>();
    ArrayList<String> contactNumbers=new ArrayList<String>(); 

    try 
    {
        if(cursorNames.getCount() > 0)
        {
            while(cursorNames.moveToNext())
            {           
            String id = cursorNames.getString(cursorNames.getColumnIndex(Contacts._ID));
            contactNames.add(cursorNames.getString(cursorNames.getColumnIndex(Contacts.DISPLAY_NAME)));

            Cursor cursorNumbers =getContentResolver().query(CommonDataKinds.Phone.CONTENT_URI, null, CommonDataKinds.Phone.CONTACT_ID +" = ?", new String[]{id}, null);
            cursorNumbers.moveToFirst();
            contactNumbers.add(cursorNumbers.getString(cursorNumbers.getColumnIndex(CommonDataKinds.Phone.NUMBER)));        
            }
        }
    }
    finally
    {
      cursorNames.close();
    }

   ContactListArrayAdapter arrayAdapter = new ContactListArrayAdapter(this,contactNames,contactNumbers);
   // lv.addFooterView(b);
   listViewContacts.setAdapter(arrayAdapter);
}

现在的问题是读取 SIM 卡联系人(而不是电话联系人)，也不是读取 SIM 卡中的所有联系人。

它正在读取 SIM 中的一些联系人，确切数字是 15(而在 SIM 中有 100 多个联系人)，并且它还在 ListView 中重复联系人。

像这样

15 个联系人
然后再次在 ListView 中重复相同的 15 个联系人。

一次又一次，总共 4 次 15 次接触被重复。

我使用此代码获取联系人。

    public ArrayList<String> c_Name = new ArrayList<String>();
    public ArrayList<String> c_Number = new ArrayList<String>();
    static String[] name_Val = null;
    String[] phone_Val = null;
    String local_value = null;

ContentResolver cr1 = getContentResolver();
        String[] projection = new String[] { People._ID, People.NAME,
                People.NUMBER };
        Uri phone_contacts = People.CONTENT_URI;
        Cursor managedCursor = cr1.query(phone_contacts, projection, null,
                null, People.NAME + " ASC");
        if (managedCursor.moveToFirst()) {
            String contactname;
            String cphoneNumber;
            int nameColumn = managedCursor.getColumnIndex(People.NAME);
            int phoneColumn = managedCursor.getColumnIndex(People.NUMBER);
            Log.d("int Name", Integer.toString(nameColumn));
            Log.d("int Number", Integer.toString(phoneColumn));
            do {

                contactname = managedCursor.getString(nameColumn);
                cphoneNumber = managedCursor.getString(phoneColumn);
                Log.d("Outside cname", "ts" + contactname);
                Log.d("Outside cno", "ts" + cphoneNumber);
                if ((contactname == " " || contactname == null)
                        && (cphoneNumber == " " || cphoneNumber == null)) {
                    // displayAlert1();

                } else {
                    c_Name.add(contactname);
                    c_Number.add(cphoneNumber);
                    Log.d("contact Name", c_Name.toString());
                    Log.d("contact No", c_Number.toString());
                }
            } while (managedCursor.moveToNext());

        }

        Uri contacts = Uri.parse("content://icc/adn");

        Cursor managedCursor1 = cr1.query(contacts, null, null, null, null);

        if (managedCursor1.moveToFirst()) {

            String contactname;
            String cphoneNumber;

            int nameColumn = managedCursor1.getColumnIndex("name");
            int phoneColumn = managedCursor1.getColumnIndex("number");

            Log.d("int Name", Integer.toString(nameColumn));
            Log.d("int Number", Integer.toString(phoneColumn));

            do {
                // Get the field values
                contactname = managedCursor1.getString(nameColumn);
                cphoneNumber = managedCursor1.getString(phoneColumn);
                if ((contactname == " " || contactname == null)
                        && (cphoneNumber == " " || cphoneNumber == null)) {
                    // displayAlert1();

                } else {
                    c_Name.add(contactname);
                    c_Number.add(cphoneNumber);
                }
            } while (managedCursor1.moveToNext());

        }
        name_Val = (String[]) c_Name.toArray(new String[c_Name.size()]);
        phone_Val = (String[]) c_Number.toArray(new String[c_Name.size()]);

然后将 name_Val、phone_Val 设置为您的 ListView 。

             ContactListArrayAdapter arrayAdapter = new ContactListArrayAdapter(this,name_Val,phone_Val );
   // lv.addFooterView(b);
   listViewContacts.setAdapter(arrayAdapter);
