Delphi XE5 下TEdit控件有个属性：KeyboardType，如下图：

该属性决定了当焦点进入TEdit时，系统弹出的输入窗体，按照其帮助文件说明，不同取值的输入窗体不同，如下图：

根据不同需要选择，也可以在运行期改变取值，通过放置一个TPopupBox控件来进行设置，设计界面如下：

代码如下：

procedure TfrmKeyboard.PopupBox1Change(Sender: TObject);
begin
  case PopupBox1.ItemIndex of
    0: Edit1.KeyboardType := FMX.Types.TVirtualKeyboardType.vktDefault;
    1: Edit1.KeyboardType := FMX.Types.TVirtualKeyboardType.vktNumbersAndPunctuation;
    2: Edit1.KeyboardType := FMX.Types.TVirtualKeyboardType.vktNumberPad;
    3: Edit1.KeyboardType := FMX.Types.TVirtualKeyboardType.vktPhonePad;
    4: Edit1.KeyboardType := FMX.Types.TVirtualKeyboardType.vktAlphabet;
    5: Edit1.KeyboardType := FMX.Types.TVirtualKeyboardType.vktURL;
    6: Edit1.KeyboardType := FMX.Types.TVirtualKeyboardType.vktNamePhonePad;
    7: Edit1.KeyboardType := FMX.Types.TVirtualKeyboardType.vktEmailAddress;
  end;
end;
