((LinearLayout.LayoutParams) view.getLayoutParams()).setMargins(0,0,0,0);

               {or}

((LinearLayout.LayoutParams) view.getLayoutParams()).topMargin = 5;

OR

You can create a LayoutParams variable and set margins to it. And set LayoutParams back to the view. as below

LinearLayout.LayoutParams parmas = (LinearLayout.LayoutParams) holder.imageView.getLayoutParams();
            parmas.setMargins(0,5,0,0);
            holder.imageView.setLayoutParams(parmas);

OR

You can use it in more generic way without specifying the particular Layout.

If the view is inside RelativeLayout.

RelativeLayout.LayoutParmas

Or you can use generic ViewGroup.MarginLayoutParams without specifying parent

if (view.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
        ViewGroup.MarginLayoutParams mp = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
        mp.setMargins(0,5,0,0);
        view.requestLayout();
    }

First you need to setHasOptionsMenu(true) in onCreateView method as

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment,
                container, false);
        this.view = view;


        setHasOptionsMenu(true);


        return view;
    }

second you have to create menus.xml in res/menu/ folder

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">


    <item
        android:id="@+id/settings"
        android:icon="@drawable/settings_icon"
        android:orderInCategory="100"
        android:title="@string/settings"
        app:showAsAction="always" />


</menu>

And also you have to set menu in onCreateOptionsMenu method as

 @Override
    public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
        inflater.inflate(R.menu.menus, menu);
        super.onCreateOptionsMenu(menu, inflater);
    }

If you want to replace menus with new menus then you just have to add menu.clear()  before inflating new menus as

@Override
    public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
        menu.clear(); 
        inflater.inflate(R.menu.menus, menu);
        super.onCreateOptionsMenu(menu, inflater);
    }

The media provider provides an indexed collection of media types, such as Audio, Video, and Images, from storage devices. Each collection is organized by primary MIME type of the content; for example, image/* content is indexed for Images.

The Files collection provides a broad view for all collections, and does not filter by any MIME type.

ContentValue class lets you to put information inside an object of Key-Value pairs for columns and their value. The object can then be pass to the insert method of an instance of the SQLiteDatabase class to insert or update your WritableDatabase.

Example Code for Save image file in Android Q

        final String relativePath = Environment.DIRECTORY_PICTURES + File.separator + "Your Directory"; // save directory
        String fileName = "Your_File_Name"; // file name to save file with
        String mimeType = "image/*"; // Mime Types define here
        Bitmap bitmap = null; // your bitmap file to save

        final ContentValues contentValues = new ContentValues();
        contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, fileName);
        contentValues.put(MediaStore.MediaColumns.MIME_TYPE, mimeType);
        contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, relativePath);

        final ContentResolver resolver = context.getContentResolver();

        OutputStream stream = null;
        Uri uri = null;

        try {
            final Uri contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
            uri = resolver.insert(contentUri, contentValues);

            if (uri == null) {
                Log.d("error", "Failed to create new  MediaStore record.");
                return;
            }

            stream = resolver.openOutputStream(uri);

            if (stream == null) {
                Log.d("error", "Failed to get output stream.");
            }

            boolean saved = bitmap.compress(Bitmap.CompressFormat.JPEG, 90, stream);
            if (!saved) {
                Log.d("error", "Failed to save bitmap.");
            }
        } catch (IOException e) {
            if (uri != null) {
                resolver.delete(uri, null, null);
            }

        } finally {
            if (stream != null) {
                stream.close();
            }
        }

You know setError works on EditText and TextView. If the spinner has a list of TextView or EditText item, then you simply have to get the TextView or Editext from it. And then set error on it. You can get TextView or EditText from Selected Spinner item view by this code demo below

TextView errorTextview = (TextView) YourSpinner.getSelectedView();
errorTextview.setError("Your Error Message here");

Now the condition that checks spinner item is selected or not, if not then show an error.

if (YourSpinner.getSelectedItemPosition() > 0) {
// get selected item value
String itemvalue = String.valueOf(YourSpinner.getSelectedItem());
} else {
// set error message on spinner
TextView errorTextview = (TextView) YourSpinner.getSelectedView();
errorTextview.setError("Your Error Message here");
}

If the spinner not showing the error then you can pass the error message on the item with red color. see the code example below.

 TextView errorTextview = (TextView) spdisposition.getSelectedView();
 errorTextview.setError("");
 errorTextview.setTextColor(Color.RED);
// for show error message on spinner
 errorTextview.setText("Your Error Message here");

android:digits="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"

Full code EditText should be look like

<EditText 
android:id="@+id/edittext"
android:digits="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
android:layout_width="fill_parent"
android:hint="Enter Full Name"
android:layout_height="wrap_content" />

To show/hide password in android simply change the attribute dynamically  
android:inputtype = "textpassword" or "text" using this setTransformationMethod

Full code definition is below for show and hide password in edittext 

//Show Password
edit_password.setTransformationMethod(HideReturnsTransformationMethod.getInstance());

//Hide Password
edit_password.setTransformationMethod(PasswordTransformationMethod.getInstance());

Here one edittext with input type = password and one eye toggle ImageView button. We have to manage show/hide password using this Imageview onClick Action.

                    <RelativeLayout
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginTop="@dimen/dp10">

                    <EditText
                        android:id="@+id/edit_password"
                        android:layout_width="fill_parent"
                        android:layout_height="@dimen/dp45"
                        android:background="@drawable/edittext_bg"
                        android:hint="@string/employeelogin_form_password"
                        android:inputType="textPassword"
                        android:paddingLeft="@dimen/dp10"
                        android:paddingTop="@dimen/dp10"
                        android:paddingRight="@dimen/dp40"
                        android:paddingBottom="@dimen/dp10"
                        android:text=""
                        android:textColor="@color/postjob_bg"
                        android:textSize="@dimen/dp13" />

                    <ImageView
                        android:id="@+id/show_pass_btn"
                        android:layout_width="@dimen/dp40"
                        android:layout_height="@dimen/dp40"
                        android:layout_alignParentRight="true"
                        android:layout_centerVertical="true"
                        android:layout_marginRight="@dimen/dp5"
                        android:alpha=".5"
                        android:onClick="ShowHidePass"
                        android:padding="@dimen/dp5"
                        android:src="@drawable/show_password" />
                </RelativeLayout>

This is layout preview of Password Editext with Eye Icon On right

In Imageview Tag XML we simply add Attribute android:onClick=”ShowHidePass” for calling onclick function
ShowHidePass() directly in code

public void ShowHidePass(View view){

        if(view.getId()==R.id.show_pass_btn){

        if(edit_password.getTransformationMethod().equals(PasswordTransformationMethod.getInstance())){
        ((ImageView(view)).setImageResource(R.drawable.hide_password);

        //Show Password                 
        edit_password.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
        }
        else{
        ((ImageView)(view)).setImageResource(R.drawable.show_password);

        //Hide Password
        edit_password.setTransformationMethod(PasswordTransformationMethod.getInstance());

        }
        }
        }
