回答1:

use following method to get contact, from contact provider:

Uri contactUri = Uri.withAppendedPath(Contacts.Phones.CONTENT_FILTER_URL, Uri.encode(string));

Cursor cursor = mContext.getContentResolver().query(contactUri, null, null, null, null);

This cursor will have resultset having number same as string.

I got it by do like these.

public static String getContactName(final String phoneNumber,Context context) {
        Uri uri;
        String[] projection;
        Uri mBaseUri = Contacts.Phones.CONTENT_FILTER_URL;
        projection = new String[] { android.provider.Contacts.People.NAME };
        try {
            Class<?> c = Class
                    .forName("android.provider.ContactsContract$PhoneLookup");
            mBaseUri = (Uri) c.getField("CONTENT_FILTER_URI").get(mBaseUri);
            projection = new String[] { "display_name" };
        } catch (Exception e) {
        }
        uri = Uri.withAppendedPath(mBaseUri, Uri.encode(phoneNumber));
        Cursor cursor = context.getContentResolver().query(uri, projection, null,
                null, null);

        String contactName = "";

        if (cursor.moveToFirst()) {
            contactName = cursor.getString(0);
        }
        cursor.close();
        cursor = null;
        return contactName;
    }

Try

Uri uri;
String[] projection;
Uri baseUri = Contacts.Phones.CONTENT_FILTER_URL;
projection = new String[] { android.provider.Contacts.People.NAME };
try {
Class<?> c = Class.forName("android.provider.ContactsContract$PhoneLookup");
baseUri = (Uri) c.getField("CONTENT_FILTER_URI").get(baseUri);
projection = new String[] { "display_name" };
} catch (ClassNotFoundException e) {
    e.printStackTrace();
} catch (IllegalArgumentException e) {
    e.printStackTrace();
} catch (SecurityException e) {
    e.printStackTrace();
} catch (IllegalAccessException e) {
    e.printStackTrace();
} catch (NoSuchFieldException e) {
    e.printStackTrace();
}
uri = Uri.withAppendedPath(baseUri, Uri.encode(Uri
            .encode(phoneNumber)));
Cursor cursor =mContext.getContentResolver().query(uri,
            projection, null, null, null) ;

String fromDisplayName = null;
if (cursor != null) {
if (cursor.moveToFirst()){
    fromDisplayName = cursor.getString(0);
}
else{
    fromDisplayName="";
}
cursor.close();
} else {
    fromDisplayName="";
}
return fromDisplayName;

The Uri android.provider.Contacts.People.NAME is deprecated. But android.provider.ContactsContract$PhoneLookup is available from API level 5 only. Hence it is better to use reflections to support all phones.
