You can use the Uri class in Android to do this;  https://developer.android.com/reference/android/net/Uri.html


    Uri uri = Uri.parse(&quot;http://www.chalklit.in/post.html?chapter=V-Maths-Addition%20&amp;%20Subtraction&amp;post=394&quot;);
    String server = uri.getAuthority();
    String path = uri.getPath();
    String protocol = uri.getScheme();
    Set&lt;String&gt; args = uri.getQueryParameterNames();


Then you can even get a specific element from the query parameters as such;

    String chapter = uri.getQueryParameter(&quot;chapter&quot;);  //will return &quot;V-Maths-Addition &quot;



I would like to plot some barplots on top of each other using facet_grid:

    library(ggplot2)
    
    df &lt;- group_by(mpg, manufacturer) %&gt;%
      summarise(cty = mean(cty), hwy = mean(hwy)) %&gt;%
      ungroup()
    
    df &lt;- melt(df, id.vars = &quot;manufacturer&quot;)
    
    ggplot() +
      geom_bar(data =df, aes(x = variable, y = value), stat = &quot;identity&quot;) +
      facet_grid(manufacturer ~ ., switch = &quot;y&quot;)

I use the ```switch```argument of ```ggplot2::facet_grid()```to let the facet labels be displayed on the y-axis instead of on top of each facet. Problem is that the facet labels are plotted vertically and therefore cropped. Is there any way to plot the facet -labels horizontally? All the questions I found so far related to rotating the x-axis labels only, not the facet labels.

How can I replace below lines with the new version of D3 API?

I have already replaced `scale.linear()` with `scaleLinear()`

    var xRange = d3.scaleLinear()
        .domain([OIResults.min,OIResults.max]).range([40, 360]);
     
    var yRange = d3.scaleLinear()
        .domain(y_domain).range([360, 40]);

Below Lines need to be replaced according to the new API: 
        
    var xAxis = d3.svg.axis().scale(xRange).tickFormat(function(d) { return d.x;});
    var yAxis = d3.svg.axis().scale(yRange).orient(&quot;left&quot;);

I&#39;m interested in sorting a list from a stream. This is the code I&#39;m using:

    list.stream()
        .sorted((o1, o2)-&gt;o1.getItem().getValue().compareTo(o2.getItem().getValue()))
        .collect(Collectors.toList());

Am I missing something? The list is not sorted afterward.

It should sort the lists according to the item with the lowest value.

    for (int i = 0; i &lt; list.size(); i++)
    {
       System.out.println(&quot;list &quot; + (i+1));
       print(list, i);
    }

And the print method:

	public static void print(List&lt;List&gt; list, int i)
    {
        System.out.println(list.get(i).getItem().getValue());
    }

How in java, can I send a request with `x-www-form-urlencoded header`. I don&#39;t understand how to send a body with a key-value, like in the above screenshot.

I have tried this code:

    String urlParameters =
      cafedra_name+ data_to_send;
    URL url;
        HttpURLConnection connection = null;  
        try {
          //Create connection
          url = new URL(targetURL);
          connection = (HttpURLConnection)url.openConnection();
          connection.setRequestMethod(&quot;POST&quot;);
          connection.setRequestProperty(&quot;Content-Type&quot;, 
               &quot;application/x-www-form-urlencoded&quot;);
    			
          connection.setRequestProperty(&quot;Content-Length&quot;, &quot;&quot; + 
                   Integer.toString(urlParameters.getBytes().length));
          connection.setRequestProperty(&quot;Content-Language&quot;, &quot;en-US&quot;);  
    			
          connection.setUseCaches (false);
          connection.setDoInput(true);
          connection.setDoOutput(true);
    
          //Send request
          DataOutputStream wr = new DataOutputStream (
                      connection.getOutputStream ());
          wr.writeBytes (urlParameters);
          wr.flush ();
          wr.close ();

But in the response, I don&#39;t receive the correct data.

This calling is deprecated:

But I can&#39;t understand which method I have to use instead of `createCriteria`.

I&#39;ve seen some questions and answers about custom events for firebase analytics, but i just wanted to ask you a straight question so you can give me a straight answer :)

So, this is my method for logging:

    @Override
    public void logFeatureSelectedEvent(String categoryName, String actionName, String labelName) {
        Bundle bundle = new Bundle();
        bundle.putString(EventTrackingKeys.EventTypes.CATEGORY, categoryName);
        bundle.putString(EventTrackingKeys.EventTypes.ACTION, actionName);
        bundle.putString(EventTrackingKeys.EventTypes.LABEL, labelName);
        mFirebaseAnalytics.logEvent(EventTrackingKeys.EventAnalyticTypes.FEATURE_SELECTED_EVENT, bundle);
    }

with custom event/key names:
       
    String CATEGORY = &quot;category&quot;;
    String ACTION = &quot;action&quot;;
    String LABEL = &quot;label&quot;;
    String FEATURE_SELECTED_EVENT = &quot;feature_selected_event&quot;;

So, in my firebase console I only get event name &quot;feature_selected_event&quot;, without custom parameter names.. 
I&#39;ve seen some answers that i should call setUserProperty() method and register that user property in the User Properties tab of Firebase Analytics. 
Is this the right way to implement that method? :

       @Override
    public void logFeatureSelectedEvent(String categoryName, String actionName, long value) {
        Bundle bundle = new Bundle();
        bundle.putString(EventTrackingKeys.EventTypes.CATEGORY, categoryName);
        bundle.putString(EventTrackingKeys.EventTypes.ACTION, actionName);
        bundle.putLong(EventTrackingKeys.EventTypes.VALUE, value);
        mFirebaseAnalytics.setUserProperty(EventTrackingKeys.EventTypes.CATEGORY, categoryName);
        mFirebaseAnalytics.setUserProperty(EventTrackingKeys.EventTypes.ACTION, actionName);
        mFirebaseAnalytics.setUserProperty(EventTrackingKeys.EventTypes.VALUE, value);
        mFirebaseAnalytics.logEvent(EventTrackingKeys.EventAnalyticTypes.FEATURE_SELECTED_EVENT, bundle);
    }

I&#39;m trying to set my custom drawable (line) for DividerItemDecoration, but with no success. Where is the mistake?

                    LinearLayoutManager.VERTICAL);
    dividerItemDecoration.setDrawable(getContext().getResources().getDrawable(R.drawable.sk_line_divider));

How do you build a lambda expression for the EditText addTextChangeListener in Kotlin? Below gives an error:


    passwordEditText.addTextChangedListener { charSequence  -&gt;
        try {
            password = charSequence.toString()
        } catch (error: Throwable) {

I&#39;ve made a list of items a few times using Android&#39;s `RecyclerView`, but it is a rather complicated process. Going through one of the numerous tutorials online works ([this][1], [this][2], and [this][3] are good), but I am looking a bare bones example that I can copy and paste to get up and running quickly. Only the following features are necessary:

- Vertical layout
- A single TextView on each row
- Responds to click events

Because I have wished for this several times, I finally decided to make the answer below for my future reference and yours.
