recyclerView layout grid items not aligning properly

i don't know much about java, just started, so i will have difficulties understanding the answers. emli5.
screenshot:
expected output:
in the recyclerview (right), these items are not aligning up like i want them to.
I want that each cell has a fixed size, and maximum number of columns possible in the grid.
spacing b/w each cell (both vertical and horizontal) is equal to (left space) divided by (number of columns minus one). [with no extra space left at start, top, bottom or end]
here is the code:

You need to create a custom item decoration by extending RecyclerView.ItemDecoration. You can do something like this:
import android.graphics.Rect;
import android.view.View;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
public class GridSpacingItemDecoration extends RecyclerView.ItemDecoration {
private final int numberOfColumns;
private final int spacing;
private final boolean addSpacingToPerimeter;
public GridSpacingItemDecoration(int numberOfColumns, int spacing, boolean addSpacingToPerimeter) {
this.numberOfColumns = numberOfColumns;
this.spacing = spacing;
this.addSpacingToPerimeter = addSpacingToPerimeter;
}
#Override
public void getItemOffsets(#NonNull Rect outRect, #NonNull View view, RecyclerView parent, #NonNull RecyclerView.State state) {
int position = parent.getChildAdapterPosition(view); // item position
int column = position % numberOfColumns; // item column
if (addSpacingToPerimeter) {
outRect.left = spacing - column * spacing / numberOfColumns;
outRect.right = (column + 1) * spacing / numberOfColumns;
if (position < numberOfColumns) { // top edge
outRect.top = spacing;
}
outRect.bottom = spacing; // item bottom
} else {
outRect.left = column * spacing / numberOfColumns;
outRect.right = spacing - (column + 1) * spacing / numberOfColumns;
if (position >= numberOfColumns) {
outRect.top = spacing; // item top
}
}
}
}
and then use it like this
int numberOfColumns = 3; // 3 columns
int spacing = 50; // 50px
boolean addSpacingToPerimeter = false;
recyclerView.addItemDecoration(new GridSpacingItemDecoration(numberOfColumns, spacing, addSpacingToPerimeter))
The GridSpacingItemDecoration class takes as a parameter the number of columns, the spacing in pixel and a boolean value that specifies whether you want spacing to be added to the list's perimeter as well. This boolean if set to true will add the given spacing as a margin not only between the grid adapter's items, but also between the items and the whole recyclerView.
Keep in mind that spacing is in pixels. So if you want to use dp instead, you can convert dp to px using
Math.round(dpValue * getResources().getDisplayMetrics().density))

It seems like every item has right padding.
You should use addItemDecoration on your RecyclerView instead.
Or use this: https://github.com/grzegorzojdana/SpacingItemDecoration

My app won't enter the for loop even though all conditions are satisfied [closed]

I am working on an app, for which I want a for loop to run. The for loop is inside a listview adapter, and it basically runs to get the some data from each entry of the list (hence the for loop). But, on debugging, I find that the app never enters the for loop, and just moves on to the 'if statement' given just below it. The condition that i == size of list isn't satisfied, so it should be running. Why?

//subtaskList.add(subtaskPartTwo);
adapter.addANewSubTask(subtaskPartTwo);
}
}
}

Before each iteration of the for loop, program checks if the condition (i == values.size()) is satisfied . As i is equal to 0, it is not equal to values.size(), so the block will not be executed.
Do you want the more common i < values.size() or possibly i <= values.size()?

The adapter's GetView method will be called multiple times, so it is not the correct place to put the for/while loop for totaling as you will have unexpected results. if you want to total anything put that inside the fragment or activity class where you are using the adapter to populate the recycler view. Ya, you can also set inside the constructor of the adapter too, if the ArrayList which you are passing at the time of initialization is not going to be changed.

Recycler view list items are showing duplicate few items at the bottom of listview

I have one recycle list view .In this I have one button .on click list view item button shows.On button click I hit one api to perform action .After performing action ,at the bottom of list automatically one item get repeat. when ever I perform api hit action same time items add at the bottom of list .Like as I perform api hit action 4 times then every time one-one item get add at the bottom of list . Please provide me solution to resolve this.

The problem is in this line.Remove the line below from your code
MainActivity mainActivity = new MainActivity();
mainActivity.showDialog();
You never ever create an Activity's instance with new operator. Its android Component class it initializes automatically with Intent . All Activities in android must go through a lifecycle so that they have a valid context attached to them. Read Activity.
The solution for this problem.
if(getActivity()!=null){
((MainActivity)getActivity()).showDialog()
}
For your new problem which you mentioned in comments.
You never assign myAnimalQuizFragment so it will give you NullPointerException anyway . Access it from your MainActivity.
((MainActivity)getActivity()).myAnimalQuizFragment.resetAnimalQuiz();
Make myAnimalQuizFragment as public in MainActivity.

Issue with checkbox checked

i am use this for setting checkbox in listview i have follow all step as per given tutorial, but there are some critical issue with output, is that when i am select first checkbox and scroll down it will change selected item and automatically appear 3rd.
so i think there are something wrong with getview. so please help me out this ....
here is my code ::
package com.AppFavorits;

}
}
}

I really don't understand your code exactly what you are trying to do. I haven't seen before this you are checking holder == null where as it should be convertView == null. If you have a scrolling issue you can check my blog post
holder = (ViewHolder) row.getTag();
if (holder == null) {
holder = new ViewHolder(row);
row.setTag(holder);
...
}
else {
row = convertView;
((ViewHolder) row.getTag()).chkbxFavrowsel.setTag(mlist
.get(position));
}

Use Below Code to your MainActivity.java file.
public class ListViewActivity extends Activity {
ListView mLstView1;
Button mBtn1;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mLstView1 = (ListView) findViewById(R.id.mLstView1);
String[] lv_items = { "Dipak", "Rahul", "Hiren", "Nandlal", "Keyur",
"Kapil", "Dipak", "Rahul", "Hiren", "Nandlal", "Keyur",
"Kapil" };
;
mLstView1.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice, lv_items));
mLstView1.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
mBtn1 = (Button) findViewById(R.id.mBtn1);
mBtn1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// Using a List to hold the IDs, but could use an array.
List<Integer> checkedIDs = new ArrayList<Integer>();
// Get all of the items that have been clicked - either on or
// off
final SparseBooleanArray checkedItems = mLstView1
.getCheckedItemPositions();
for (int i = 0; i < checkedItems.size(); i++) {
// And this tells us the item status at the above position
final boolean isChecked = checkedItems.valueAt(i);
if (isChecked) {
// This tells us the item position we are looking at
final int position = checkedItems.keyAt(i);
// Put the value of the id in our list
checkedIDs.add(position);
System.out.println("Position is:- " + position);
}
}
}
});
}
}
