喜  我需要创建一个autocompletetextview中建议应的联系人姓名和组织名称的组合，现在用2.1操作系统。我可以显示联系人的姓名，但orgnization名没有，我怎么能做到这一点。

 公共类myactivity延伸活动{
    / **第一次创建活动时调用。 * /
    公共静态的EditText编辑;
    私人字符串ID;
    @覆盖
    公共无效的onCreate（包savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;
        AutoCompleteTextView行为=（AutoCompleteTextView）findViewById（R.id.AutoCompleteTextView01）;
        ED =（EditText上）findViewById（R.id.EditText01）;
        ContentResolver的内容= getContentResolver（）;
        光标光标= content.query（ContactsContract.Contacts.CONTENT_URI，PEOPLE_PROJECTION，NULL，NULL，NULL）;
        ContactListAdapter适配器=新ContactListAdapter（这一点，光标）;
        act.setThreshold（0）;
        act.setAdapter（适配器）;

}


    公共静态最后的String [] PEOPLE_PROJECTION =新的String [] {
        ContactsContract.Contacts._ID，
        Contacts.DISPLAY_NAME，

        ContactsContract.Contacts.HAS_PHONE_NUMBER
    };

}
类ContactListAdapter扩展的CursorAdapter实现过滤的{
    私人ContentResolver的MCR;

    公共ContactListAdapter（上下文的背景下，光标C）{
        超（背景下，C）;
        MCR = context.getContentResolver（）;
    }


    @覆盖
    公共无效bindView（查看视图，上下文的背景下，光标光标）{


             （（TextView中）查看）.setText（cursor.getString（1））;
    }


    @覆盖
    公共查看NewView的（上下文的背景下，光标光标的ViewGroup父）{
         最后LayoutInflater充气= LayoutInflater.from（上下文）;
            最后的TextView视图=（TextView中）inflater.inflate（android.R.layout.simple_dropdown_item_1line，父母，假）;


            view.setText（cursor.getString（1））;

            返回查看;

    }
    @覆盖
    公共字符串convertToString（光标指针）{



        返回cursor.getString（1）;
    }
    公共光标runQueryOnBackgroundThread（CharSequence的约束）{
        如果（getFilterQueryProvider（）！= NULL）{
            返回getFilterQueryProvider（）runQuery（约束）。
        }

        StringBuilder的缓冲= NULL;
        字串[] args = NULL;
        如果（约束！= NULL）{
            缓冲区=新的StringBuilder（）;
            buffer.append（UPPER（）;
            buffer.append（Contacts.DISPLAY_NAME）;
            buffer.append（）GLOB？）;
            的args =新的String [] {constraint.toString（）与toUpperCase（）+*};
        }

        返回mCR.query（ContactsContract.Contacts.CONTENT_URI，myactivity.PEOPLE_PROJECTION，缓冲== NULL空：buffer.toString（），指定参数时，
                Contacts.DISPLAY_NAME）;
    }

}
 

解决方案

要检索的组织名称，你应该寻找的数据表中以下方式：

 私有静态最后弦乐ORGANIZATION_PROJECTION =新的String [] {
    ContactsContract.CommonDataKinds.Organization.COMPANY
}

公共字符串getOrganizationForContact（INT CONTACT_ID）{
    光标C;
    字符串组织= NULL;

    C = getContentResolver（）查询（ContactsContract.Data.CONTENT_URI，
            ORGANIZATION_PROJECTION，
            ContactsContract.Data.MIMETYPE +=？和+ ContactsContract.Data.CONTACT_ID +=？，
            新的String [] {ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE，+ CONTACT_ID}，
            空值
        ）;

    如果（C =空＆安培;！＆安培; c.moveToFirst（））{
        有机= c.getString（0）;
    }

    c.close（）;
    返回组织;
}
 

PS：我没有尝试这样做code，但一个非常类似的。我希望这也能工作，或者至少，它可以帮助

Hi i need to create an autocompletetextview in which suggestion should be a combination of Contact name and organization name ,am using 2.1 os. i can display the contact name ,but orgnization name not, how can i do this.

public class myactivity extends Activity {
    /** Called when the activity is first created. */
    public static EditText ed;
    private String id;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        AutoCompleteTextView act=(AutoCompleteTextView)findViewById(R.id.AutoCompleteTextView01);
        ed=(EditText)findViewById(R.id.EditText01);
        ContentResolver content = getContentResolver();
        Cursor cursor = content.query(ContactsContract.Contacts.CONTENT_URI,PEOPLE_PROJECTION, null, null, null);
        ContactListAdapter adapter = new ContactListAdapter(this, cursor);
        act.setThreshold(0);
        act.setAdapter(adapter);

}


    public static final String[] PEOPLE_PROJECTION = new String[] {  
        ContactsContract.Contacts._ID,
        Contacts.DISPLAY_NAME,

        ContactsContract.Contacts.HAS_PHONE_NUMBER
    };

}
class ContactListAdapter extends CursorAdapter implements Filterable {  
    private ContentResolver mCR;

    public ContactListAdapter(Context context, Cursor c) {  
        super(context, c);  
        mCR = context.getContentResolver();  
    }


    @Override
    public void bindView(View view, Context context, Cursor cursor) {


             ((TextView) view).setText(cursor.getString(1));
    }


    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
         final LayoutInflater inflater = LayoutInflater.from(context);
            final TextView view = (TextView) inflater.inflate( android.R.layout.simple_dropdown_item_1line, parent, false);


            view.setText(cursor.getString(1));

            return view;

    }  
    @Override
    public String convertToString(Cursor cursor) {  



        return cursor.getString(1);
    }
    public Cursor runQueryOnBackgroundThread(CharSequence constraint) {
        if (getFilterQueryProvider() != null) {
            return getFilterQueryProvider().runQuery(constraint);
        }

        StringBuilder buffer = null;
        String[] args = null;
        if (constraint != null) {
            buffer = new StringBuilder();
            buffer.append("UPPER(");
            buffer.append(Contacts.DISPLAY_NAME);
            buffer.append(") GLOB ?");
            args = new String[] { constraint.toString().toUpperCase() + "*" };
        }

        return mCR.query(ContactsContract.Contacts.CONTENT_URI,myactivity.PEOPLE_PROJECTION ,    buffer == null ? null : buffer.toString(), args,
                Contacts.DISPLAY_NAME);
    }

}

To retrieve the Organization name you should search the Data table in the following way:

private static final String ORGANIZATION_PROJECTION = new String[] {     
    ContactsContract.CommonDataKinds.Organization.COMPANY
}

public String getOrganizationForContact ( int contact_id ) {
    Cursor c;
    String org = null;

    c = getContentResolver().query ( ContactsContract.Data.CONTENT_URI,
            ORGANIZATION_PROJECTION,
            ContactsContract.Data.MIMETYPE + "=? AND " + ContactsContract.Data.CONTACT_ID + " =?",
            new String[] { ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE, "" + contact_id },
            null
        );

    if ( c != null && c.moveToFirst() ) {
        org = c.getString ( 0 );
    }

    c.close();
    return org;
}

PS: I haven't tried this code, but a very similar one. I hope this will work too, or at least that it helps
