android - How to achieve ripple animation using support library? -

-

I am trying to add a wave animation to the click button. I was like below but it requires minSdKVersion 21.

ripple.xml 

  & lt; Wave xmlns: android = "http://schemas.android.com/apk/Native/Android" Android: Color = "? Android: colorControlHighlight" & gt; & Lt; Items & gt; & Lt; Size Android: shape = "rectangle" & gt; & Lt; Solid Android: Color = "Android: Color Score" /> & Lt; / Size & gt; & Lt; / Item & gt; & Lt; / Wave & gt;

button 

  & lt; Com.devspark.robototextview.widget.RobotoButtonAndroid: id = "@ + id / loginButton" Android: layout_width = "match_parent" Android: layout_height = "wrap_content" Android: background = "@drawable / rip" Android: text = "@ String / login_button "/>

I want to make it backward backward compatible with the design library.

How can this be done?

original waveform setup

  • < P> The inherent wave in the scene.

  • Ripples that extend beyond the bounds of the scenes:
    Android: background = "selectablebestgroundbroadgroundborderless"

    In Java code, ? (Attr) for xml references.

Support ? Android: attr instead of ? Attr: Returns

    by using (or ? shorthand), so the API is available back to 7.

Wave with picture / background

  • The easiest solution to keep an image or background and overlaying wave View with a framelayout set with a wave setpref () or setBackground () .

There is no clear way to do this sincerely, though Nick Butcher posted the topic of wave with ImageView s.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
