in month of having single column, have several botons genre buttons dynamically query function generates buttons:

private void createempresas() {     button b;     jsonobject json = null;     int count = 0;     linearlayout lm = (linearlayout) findviewbyid(r.id.linearmain);     jsonobject jobj = obj_sqlite.get_descripcion_empresas();      try {         count = integer.parseint(jobj.getstring("cont"));         json = new jsonobject(jobj.getstring("json"));     } catch (exception e) {         log.e("getparams", e.getmessage());     }      (int x = 1; x <= count; x++) {          try {             jsonobject json_row = new jsonobject(json.getstring("row" + x));              b = new button(this);             b.settext(json_row.getstring("descripcion"));             b.setid(json_row.getint("empresa"));             b.settextsize(10);             b.setpadding(8, 3, 8, 3);             b.settypeface(typeface.serif, typeface.bold_italic);             b.setlayoutparams(new layoutparams(layoutparams.wrap_content,                     layoutparams.wrap_content));              lm.addview(b);              b.setonclicklistener(new view.onclicklistener() {                 public void onclick(view v) {                     // todo auto-generated method stub                     toast.maketext(getapplicationcontext(),                             "yipee.." +v.getid(), toast.length_short)                             .show();                 }             });         } catch (exception e) {             log.e("getparams", e.getmessage());         }     } }

my xml is:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/bg_main" android:paddingbottom="@dimen/activity_vertical_margin" android:paddingleft="@dimen/activity_horizontal_margin" android:paddingright="@dimen/activity_horizontal_margin" android:paddingtop="@dimen/activity_vertical_margin" tools:context="com.example.php_mysql_sqlite.mainactivity" >  <button     android:id="@+id/button4"     style="?android:attr/buttonstylesmall"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignbaseline="@+id/button6"     android:layout_alignbottom="@+id/button6"     android:layout_alignparentright="true"     android:layout_marginright="17dp"     android:background="@null"     android:onclick="loginout"     android:text="@string/btlogout"     android:textcolor="@color/red" />  <button     android:id="@+id/button6"     style="?android:attr/buttonstylesmall"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignbaseline="@+id/button5"     android:layout_alignbottom="@+id/button5"     android:layout_centerhorizontal="true"     android:onclick="syncsqlitemysql"     android:text="@string/syn" />  <button     android:id="@+id/button5"     style="?android:attr/buttonstylesmall"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignparentbottom="true"     android:layout_alignparentleft="true"     android:onclick="borrartabla"     android:text="@string/deltable" />  <scrollview     android:layout_width="285dp"     android:layout_height="330dp"     android:layout_margintop="1dp" >      <linearlayout         android:id="@+id/linearmain"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:layout_alignleft="@+id/button5"         android:layout_alignparenttop="true"         android:layout_alignright="@+id/button4"         android:background="@color/white"         android:orientation="vertical" >     </linearlayout> </scrollview>

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
