hint

问题 I've opened a bug but i was wondering if anyone encountered this issue and knows a workaround. If you define a text view with a hint inside it, give it right gravity (android:gravity="right") then if you define android:singleLine=true or android:maxLines="1" or android:scrollHorizonatally="true" you don't see the hint. removing the right gravity returns the hint to the left side, removing all the tree params i mentioned above puts the hint on the right side. i want my hint on the right, but i

问题 I know that I could change the No. of lines for EditeText's Text, yet could I change that of EditText's hint as well? I could not find a solution online. Thanks for the help. My Code: @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { inflater.inflate(R.menu.property_search, menu); super.onCreateOptionsMenu(menu, inflater); final MenuItem searchViewMenuItem = menu.findItem(R.id.action_search); mSearchView = (SearchView) searchViewMenuItem.getActionView(); int

问题 In my application in android are many EditText fields. And I ran into a problem with hint. It is not disappearing when EditText is focused, but it disappears when I start to write something. How can this problem be fixed? Because I need the hint to disappear when the EditText field is touched. It is for example: <EditText android:layout_width="260dp" android:layout_height="30dp" android:ems="10" android:inputType="text" android:id="@+id/driv_lic_num_reg" android:hint="@string/driver_license

问题 The program needs to read the values of three coordinates P1(x1,y1) P2(x2,y2) P3(x3,y3) as well as another coordinate P(x,y) and determine whether this point is inside a triangle formed from the 3 point above. 回答1: The proper way to do this is by calculating the barycentric coordinates of the fourth point given the three points of your triangle. The formula to compute them is given at the end of the section "Converting to barycentric coordinates", but I hope to provide a less mathematics

问题 I encountered an odd situation where appending OPTION (RECOMPILE) to my query causes it to run in half a second, while omitting it causes the query to take well over five minutes. This is the case when the query is executed from Query Analyzer or from my C# program via SqlCommand.ExecuteReader() . Calling (or not calling) DBCC FREEPROCCACHE or DBCC dropcleanbuffers makes no difference; Query results are always returned instantaneously with OPTION (RECOMPILE) and greater than five minutes

问题 I have the latest 5.0.1 update and the EditText hint has stopped showing: I have: <EditText android:id="@+id/editTextLocation" android:layout_width="wrap_content" android:layout_marginEnd="5dp" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:layout_marginStart="5dp" android:layout_weight="80" android:clickable="false" android:focusable="false" android:focusableInTouchMode="false" android:hint="@string/chooseLocationHint" android:longClickable="false" android:textColor

问题 Is it possible to specify a database index hint on a play framework Entity query. My code looks like: public static List<Transaction> findOnInactive(Date date) { return Transaction.find( "date = ? and account in ( select d.acctNb from account d " + " where d.date = ? and (d.inactive = true or d.blocked = true)" + " group by d.acctNb )", date, date).fetch(); } Running the generated query takes 20 sec. However running the same query manually with select * from transaction with (INDEX(_dta_index

问题 I am calling SQL Server 10 from Entity Framework in C# and want to get a query hint into the request. The database has indexes which operated normally from SQL run in Management Studio, but when calling the command from C# using Entity Framework in Visual Studio, the query planner chooses a full scan when there is already an index. I am creating dynamic predicates to request data in the following form: data.attributeText = data.vegaDB.attributeText.AsExpandable().Where(parentPredicate.Compile

问题 I am trying to make a custom hint in Lazarus. So far I have dynamically loaded the text in the hint, and customized the font face, font size, and font color. I would like to limit the width of the hint window. Any ideas? Here is my code. type TExHint = class(THintWindow) constructor Create(AOwner: TComponent); override; ... constructor TExHint.Create(AOwner: TComponent); begin inherited Create(AOwner); with Canvas.Font do begin Name := 'Hanuman'; Size := Size + 3; end; //Canvas.Width := ; end
