lvMain.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { int i = порядковый номер чекбокса от нуля; ((ViewGroup)view).getChildat(i); } }); Upd If you have onItemClick() It works when you press it. Layout or any other ViewGroup, only then can it be as exemplified as an example (GroupView)♪ Class GroupView There's a lot of all the bruises out of this lyot, orderly according to their encryption in the xml file downwards, or how you added them in the code. It's a way to get a whip. getChildAt(int) who returns from the Vewh mass on the index.

Apparently, he's on your phone, not downtown, but also on the left (but the screen's small, and it looks like it's downtown), because you've got him,android:layout_alignParentLeft="true" android:layout_alignParentStart="true" So most likely the removal of the above-mentioned attributes will solve your problem.

Logic: Recognize the length of the file in the counted variable (long filelen)If the length is acceptable, read all the contents in the baytes, for example: byte[] data = Files.readAllBytes(path); Go through the cycle datasupporting a zero-to-zero condition. boolean isZeroIf there's a change to zero, remember the position. startIf there's a change in "not zero" status, then determine the length of a zero series of zero reading starts from the current position, compare to the maximum length.It's the same thing if the file ends in zero.If the length is very large (the memory is not enough), then you'll have to put a buffer in a few megabytes and read the pieces, forget to glue the lengths of the zero series across the segments.

In your class, use the method setOnRefreshListener changing your content TextView. That's it.SwipeRefreshLayout swipeLayout = (SwipeRefreshLayout) findViewById(R.id.swipe); swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { @Override public void onRefresh() { meuTextView.setText("Aqui o novo texto ao usar o swipe refresh"); swipeLayout.setRefreshing(false); } }); XML XML XMLYours .xml can be something like this:. . .  <android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/swipe" android:layout_width="match_parent" android:layout_height="match_parent">  <TextView android:id="@+id/meuTextView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Jon Snow" android:textSize="40dp" android:layout_centerVertical="true" android:layout_centerHorizontal="true" />  </android.support.v4.widget.SwipeRefreshLayout> See more details here in https://developer.android.com/training/swipe/add-swipe-interface.html en in your application.

I'll start over.Your line. c.incrementAndGet(); according https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicInteger.html#incrementAndGet-- increases current importance c and takes his meaning, which is equivalent to recordings of normal int, for example, int c=0; System.out.println(++c); The atomic is used because you have a multi-point (Thread) annex and you need objects that can't be changed by other flows, while one flow is already approaching the variable of this facility.Stroke final int s1 = s0 + 1; creates variables s1 which should not be altered during the programme ' s work in the area of its announcement, that is, within for(;;)♪Why so many variables can explain https://vertex-academy.com/tutorials/ru/dvumernye-massivy-v-java/ website. Because you have a two-band and you need to go through all his elements.Like example, you'll have one. int[][] data={{1,2,3},{2,3,4}}; You must first, but you don't have to, run along the lines that will contain the columns. In this case, you have two lines with three pillars.In your cycle, you create final Thread[] p = new Thread[data.length]; volume of flows equal to number of lines. In my example, this is 2 Then you run every line and final int[] r = data[i]; create a mass r The one that will be equal to the number of your columns. In my example, they're 3.After that, for each column, it's on the line.for (int i = 0; i < p.length; i++) { You're creating a new flow ( Thread ) through the lambdu inside which you're doing something,for (int s0 = 0; s0 < 3 - 1; s0++) { final int s1 = 0 + 1; if (r[0] > r[1]) { final int tmp = r[0]; r[0] = r[1]; r[1] = tmp; c.incrementAndGet(); } All this can be done. Thread newThread= new Thread(new Runnable() { @Override public void run() { for (int s0 = 0; s0 < r.length - 1; s0++) { int s1 = s0 + 1; if (r[s0] > r[s1]) { final int tmp = r[s0]; r[s0] = r[s1]; r[s1] = tmp; c.incrementAndGet(); } } } }); p[i] = newThread; This example, I understand, illustrates the grading of the choice.

Good day!A method should be used to address the listed index element. get(int index)which returns the type object specified when the list is declared. Further, you will simply need to use the facility that has been received and take the necessary action.Details of the method can be found in the documentation of the platform: https://docs.oracle.com/javase/8/docs/api/java/util/ArrayList.html#get-int-

The two of "the name=id" can be added to the file. user.properties (Bin folder of JMeter Installation)site1=foo site2=bar File values can be read by function And then use normal synthaxis. https://jmeter.apache.org/usermanual/functions.html :${site1_id} ${site2_id} Moreover, values site1♪ site2 and any https://jmeter.apache.org/usermanual/properties_reference.html You can redesign the summer with help. https://jmeter.apache.org/usermanual/get-started.html#override if you launch JMeter as follows:jmeter -Jsite1=baz variable value ${site1_id} I'll be there. bazMore detailed information: https://www.blazemeter.com/blog/apache-jmeter-properties-customization/

There are others in the RSDN algorithm:a = (14 − месяц) / 12; y = год − a; m = месяц + 12 * a − 2; ДеньНедели = (7000 + (день + y + y / 4 − y / 100 + y / 400 + (31 * m) / 12)) ОСТАТОК 7; All the splits are full.Result: 0 to Sunday, 1 to Monday, etc.

If you want it. enumsuch as:public enum Days { DAYS_10(10), DAYS_20(20), DAYS_30(30), DAYS_50(50); public final int count; Days(int count) { this.count = count; } } And the value can be obtained:Days.DAYS_30.count UPDHow am I supposed to pull the braces when it's 10, 20, 30 in the table?For example:Days days; if (count == 10) days = Days.DAYS_10; else if (count == 20) days = Days.DAYS_20; else if (count == 30) days = Days.DAYS_30; else days = Days.DAYS_50;

In a number-related file, we need to be replaced by unique identifiers For example: In [X] hours a tourist [X] km, what's the traveler's distance in [X] hours? And then in the violin itself, replace the identifiers with the predominant values.

The terms are badly used in the question.There is the instance variable, the class variable, and the local variable, besides the parameter that is actually a local variable that is initialized by its call.Never heard the term method header at most https://pt.stackoverflow.com/q/39870/101 But I understand what you mean.There is no variable within the parameter, there is variable that is https://pt.stackoverflow.com/q/32448/101 .When there is name collision the local variable always has priority, the this usually used to disambigunate."The local variable simulates the instance variable in the method body"No. When there is no collision the instance variable can be accessed directly in the same way as the local variable, but it is only a ease of syntax, the semantics is not local variable.Values are not implemented. We are not talking about allocation there, nor is it anything attributed to methods.this.name = name; is taking the value of the local variable name, which by chance is a parameter, and is assigning to the instance variable nameThat's all.The second part of the question seems to have nothing to do with the first part, but let's go.You use in the builder what you need to build, what you don't need doesn't use. See more in https://pt.stackoverflow.com/q/73530/101 . But instance methods should not be referenced in the constructor, because until the construction is finished they not invalid.I would start by trying to understand things as they really are, give right names to things. The fact that this is still confused will harm learning. The final part of the question is extremely confusing and probably not even part of the scope of this site to answer that, outside that it does not seem to be part of the rest of the question. Without the most basic understanding I would not even try to insist on it.The question is part of other potentially wrong assumptions, but I will not even enter into this merit which is something more advanced.

It's weird that the question arose in category java because you don't ask anything new, but you're just doing MAPU where the key is the name of the type, and the meaning of the type itself, I think it's not that, it's not that memory, it's not rhyming, and keeping it all in that kind of thing.
