android - How to properly trigger a datePicker and validation from an EditText? -
i trying validation of edittext field, allow me elaborate because using bunch of concepts have own questions in stackoverflow have feeling i'm trying not yet answered in of them, , rather basic either i'm screwing badly or found bug, also, many of popular questions , answers couple of years old...
i have 2 edittext fields contain initial date , termination date input datepicker, validating after termination date has been input datepicker date happens after initial date, , if doesn't displays error using seterror.
so far good, manage there bothering me:
when first click on edittext nothing (because use setinputtype(inputtype.type_null) along android:focusableintouchmode="true" in xml; avoid showing me keyboard, clicks, selected, , no keyboard, no datepicker, until click again, onclick method triggers datepicker , works intended.)
i going show images don't have rep points :/
if use setfocusable(false), weird happens, when seterror comes icon shows without text.
if don't use setfocusable(false), edittext appears selected when activity starts (no cursor flashing because disabled input) , stays selected (it stays blue can click anywhere)
if don't want selected @ start use android:focusableintouchmode="true" in xml in parent layout, per recommendation of question (stop edittext gaining focus @ activity startup) , solves problem. have first click , nothing happens second click , shows datepicker problem again... doing wrong.

i have similar "problem" concerning error message , focusability. if textview not focusable message isn't shown. suppose how works e.g. if have many fields validated , validation error in each of them, message shown textview contains cursor.
in app i'm using time , date picker way do. have textviews validated not focusable. layout looks this:
<linearlayout android:id="@+id/time" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginleft="10dp" android:layout_marginright="10dp" android:layout_margintop="10dp" android:background="@drawable/box_bg" android:orientation="horizontal"> <textview android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingright="13dp" android:text="@string/start_time" /> <edittext android:id="@+id/edittext_start_time" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginright="10dp" android:layout_weight="1" android:focusable="false" android:inputtype="none" android:onclick="showtimepicker" /> <textview android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingleft="10dp" android:paddingright="13dp" android:text="@string/end_time" /> <edittext android:id="@+id/edittext_end_time" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginright="10dp" android:layout_weight="1" android:focusable="false" android:inputtype="none" android:onclick="showtimepicker" /> </linearlayout> maybe solve problem textviews getting focus automatically. if not, let know , figure out.
[edit] here code snippet i'm using:
<tablerow android:id="@+id/tablerow" android:layout_marginbottom="3dp" android:layout_margintop="3dp" android:background="@drawable/box_bg" android:baselinealigned="false"> <textview android:id="@+id/text_view_birthday" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_column="0" android:layout_gravity="center_vertical" android:layout_span="1" android:text="@string/birthday" /> <edittext android:id="@+id/text_birthday" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_column="1" android:layout_gravity="center_vertical" android:cursorvisible="false" android:editable="false" android:focusable="false" android:focusableintouchmode="false" android:inputtype="date|textnosuggestions" android:layout_weight="1" android:layout_span="2" /> </tablerow>
