Create a custom BitmapImageViewTarget to load the image into: public class CircularBitmapImageViewTarget extends BitmapImageViewTarget { private Context context; private ImageView imageView; public CircularBitmapImageViewTarget(Context context, ImageView imageView) { ...

Strikethrough the entire text String sampleText = "This is a test strike"; textView.setPaintFlags(tv.getPaintFlags()| Paint.STRIKE_THRU_TEXT_FLAG); textView.setText(sampleText); Output: This is a test strike Strikethrough only parts of the text String sampleText = "This is a...

Same as above in the FOR SYSTEM_TIME FROM <start_date_time>TO <end_date_time> description, except the table of rows returned includes rows that became active on the upper boundary defined by the <end_date_time> endpoint. SELECT * FROM Employee FOR SYSTEM_TIME BETWEEN '201...

As the characters/digits can be anywhere within the string, we require lookaheads. Lookaheads are of zero width meaning they do not consume any string. In simple words the position of checking resets to the original position after each condition of lookahead is met. Assumption :- Considering non-wo...

This can be done with a bit of modification in the above regex ^(?=.{10,}$)(?=(?:.*?[A-Z]){2})(?=.*?[a-z])(?=(?:.*?[0-9]){2}).*$ or ^(?=.{10,}$)(?=(?:.*[A-Z]){2})(?=.*[a-z])(?=(?:.*[0-9]){2}).* Let's see how a simple regex ^(?=(?:.*?[A-Z]){2}) works on string abcAdefD Image Credit :- ht...

In the solver file, we can set a global regularization loss using the weight_decay and regularization_type options. In many cases we want different weight decay rates for different layers. This can be done by setting the decay_mult option for each layer in the network definition file, where decay_...

To start drawing a shape you need to define a pen object The Pen accepts two parameters: Pen Color or Brush Pen Width The Pen Object is used to create an outline of the object you want to draw After Defining the Pen you can set specific Pen Properties Dim pens As New Pen(Color.Purple) ...

Use parentheses and commas to write tuple types. Use one comma to write a pair type. (Int, Int) Use more commas to write tuple types with more components. (Int, Int, Int) (Int, Int, Int, Int) Tuples can contain values of different types. (String, Int, Char) Tuples can contain complex ...

Use the curry function (from Prelude or Data.Tuple) to convert a function that takes tuples to a function that takes two arguments. curry fst 1 2 -- computes 1 curry snd 1 2 -- computes 2 curry (uncurry f) -- computes the same as f import Data.Tuple (swap) curry swap 1 2 -- computes (2, 1...

Use swap (from Data.Tuple) to swap the components of a pair. import Data.Tuple (swap) swap (1, 2) -- evaluates to (2, 1) Or use pattern matching. case (1, 2) of (x, y) => (y, x) -- evaluates to (2, 1)

A. The syntax is presented above. The following selector matches all <input> elements in an HTML document that are not disabled and don't have the class .example: HTML: <form> Phone: <input type="tel" class="example"> E-mail: <input type="em...

By default, LESS will use its own calc() unless told otherwise. So: @column-count: 2; .class-example { width: calc(100% / @column-count); } Would compile to this: .class-example { width: 50%; } While it is our desired width, LESS has used it's own calc() function to calculate ...

The GNU gprof profiler, gprof, allows you to profile your code. To use it, you need to perform the following steps: Build the application with settings for generating profiling information Generate profiling information by running the built application View the generated profiling inf...

import groovy.json.JsonOutput; def json = JsonOutput.toJson([foo: 'bar', baz: [1]]) assert json == '{"foo":"bar","baz":[1]}' In addition to maps, lists and primitives groovy.json.JsonOutput also supports a POJOs serialitzation: import groovy.json.JsonOutput; ...

Dirty reads (or uncommitted reads) are reads of rows which are being modified by an open transaction. This behavior can be replicated by using 2 separate queries: one to open a transaction and write some data to a table without committing, the other to select the data to be written (but not yet com...

To create a custom standalone Gradle plug-in using java (you can also use Groovy) you have to create a structure like this: plugin |-- build.gradle |-- settings.gradle |-- src |-- main | |-- java | |-- resources | |-- META-INF | |-- gradle-plugins ...

Let's assume that we have one row in Company table with companyId 1. We can insert row in employee table that has companyId 1: insert into Employee values (17, 'John', 1) However, we cannot insert employee that has non-existing CompanyId: insert into Employee values (17, 'John', 111111) Msg ...

This is a basic Hello World program in NASM assembly for 32-bit x86 Linux, using system calls directly (without any libc function calls). It's a lot to take in, but over time it will become understandable. Lines starting with a semicolon(;) are comments. If you don't already know low-level Unix sy...

A switch is a command line argument which takes no value. It can be specified with: desc.add_options() ("hidden", po::bool_switch()->default_value(false), "Hide your name"); And used with: if (vm["hidden"].as<bool>()) std::cout << "Hello ...
