和某牛讨论Delphi读Android联系人.写了如下代码
uses
FMX.Helpers.Android,
Androidapi.JNI.JavaTypes, Androidapi.JNI.GraphicsContentViewText,
FMX.Platform.Android, Androidapi.JNIBridge, Androidapi.JNI.Provider,
Androidapi.Helpers;
procedure QueryContact(AName: string; AList: TStrings);
var
cursorContactsPhone: JCursor;
selection: string;
projection: TJavaObjectArray;
FieldIndex: Integer;
begin
if AList <> nil then
AList.Clear;
projection := nil;
if AName.Length > 0 then
begin
projection := TJavaObjectArray.Create(1);
projection.Items[0] := TJContacts_PeopleColumns.JavaClass.DISPLAY_NAME;
selection := JStringToString(TJContacts_PeopleColumns.JavaClass.DISPLAY_NAME)+’ LIKE “%’ + AName + ‘%”‘;
end;
//select projection from 联系人数据库 where selection
cursorContactsPhone := SharedActivity.getContentResolver.query
(TJCommonDataKinds_Phone.JavaClass.CONTENT_URI,
projection {要查询的字段名,nil的全部},
StringToJString(selection){Where条件},
nil { 这里是Where语句的条件参数们,我上面图方便,写死在Where条件中了,没使用参数 } , nil);
if AList <> nil then
while (cursorContactsPhone.moveToNext) do
begin
//获取字段的ColumnIndex
FieldIndex := cursorContactsPhone.getColumnIndex
(TJContacts_PeopleColumns.JavaClass.DISPLAY_NAME);
//读字段内容
AList.Add(JStringToString(cursorContactsPhone.getString(FieldIndex)));
end;
cursorContactsPhone.close;
end;
procedure TForm2.Button1Click(Sender: TObject);
var
s: TStrings;
begin
s := TStringList.Create;
QueryContact(‘王’, s); //查询姓王的人
ShowMessage(s.Text);
s.Free;
end;
我是个懒人,不想再深究了.
对了,别忘了Android有权限,加上读取联系人的权限
