android - Override onMeasure after getting ImageView by Id -


i need find view id , override onmeasure method. know how that?

the following not work in java, conceptually it's need:

imageview myimage = (imageview) findviewbyid(r.id.some_pic); myimage.onmeasure(int widthmeasurespec, int heightmeasurespec) {   super.onmeasure(widthmeasurespec, heightmeasurespec);   int width = measurespec.getsize(widthmeasurespec);   int height = measurespec.getsize(heightmeasurespec);     showother(width, height); };  myimage.setimagebitmap(bmp);

java offers this

imageview myimage = new imageview(this) {   @override   protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {     super.onmeasure(widthmeasurespec, heightmeasurespec);     int width = measurespec.getsize(widthmeasurespec);     int height = measurespec.getsize(heightmeasurespec);     showother(width, height);               } };

or this

imageview myimage. = (imageview) findviewbyid(r.id.some_pic); myimage.setimagebitmap(bmp);

i thought of using setonmeasurelistener no such method defined imageview. thoughts on how going?

i'm guessing some_pic imageview declared in xml , inflated, calling setcontentview in activity class. inflation means android reads xml , translates java objects. once call setcontentview, objects instantiated, , after it's late make changes classes, such overriding imageview's onmeasure method.

i can think of 2 options:

  1. (preferred) create new class extends imageview , overrides onmeasure. when declare some_pic in xml, instead of using imageview tag, name tag after new class (fully qualified name):

    <com.mycompany.myproject.myimageview
        android:id="@+id/some_pic"
        ...
    />

  2. don't declare some_pic in xml. in activity's oncreate method, after call setcontentview, instantiate new imageview , override onmeasure method, did in question's first java option. you'll have manually insert imageview layout; use google learn how insert view view (here's example).

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
