How to change bottom margin of swipeRefreshlayout programmatically?

Question

I have such layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    tools:context=".jobAGENT.JobsList">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="75dp"
        android:gravity="center_horizontal"
        android:text="@string/no_jobs"
        android:textSize="32sp"
        android:textStyle="italic"
        android:visibility="gone" />

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/refresh_t"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginStart="5dp"
        android:layout_marginTop="10dp"
        android:layout_marginBottom="5dp"
        android:background="@color/white">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/job_list_t"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginStart="10dp"
            android:layout_marginTop="10dp"
            android:layout_marginEnd="10dp"
            android:layout_marginBottom="10dp" />

    </android.support.v4.widget.SwipeRefreshLayout>

    <ProgressBar
        android:id="@+id/loader"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:visibility="gone" />


</RelativeLayout>

I would like to change margin of RecyclerView and SwipeRefreshLayout programmatically when I reach some conditions. For example, at my onScrollListener when my list reaches its end I would like to change bottom margin of my views and show progressbar below it. I saw this and this questions and I have also managed to change margin of refreshLayout but the last item of RV become cut and I think that I have to change margin of RV also. But I can't get layout params of this view. For refreshLayout I used smth like that:

val param = refreshLayout.layoutParams as RelativeLayout.LayoutParams
param.setMargins(5,10,5,150)
refreshLayout.layoutParams = param

and it works good, but how I can also change margin of recyclerview which is placed inside refresh layout?

Answer 1

一条建议，而不是在到达滚动端时将进度条添加到recyclerview的最后一个位置上……这将确保显示进度条。在recyclerview中很容易拥有多种类型的查看器这应该可以解决您的问题，而无需添加任何边距/填充

Answer 2

Last item in your RecyclerView cuts, meaning, you'll have to add padding only to the last element of RecyclerView , instead of giving padding to complete RecyclerView .

You can do that by setting android:clipToPadding="false ", and giving it paddingBottom equal to the height of your SwipeRefreshLayout .

You can do that as follows:

<android.support.v7.widget.RecyclerView
    android:paddingBottom="56dp"
    android:clipToPadding="false"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Adjust the paddingBottom as per your need.

try this..

RecyclerView.LayoutParams params = new RecyclerView.LayoutParams(
            RecyclerView.LayoutParams.MATCH_PARENT,
            RecyclerView.LayoutParams.MATCH_PARENT
    );
    params.setMargins(50, 50, 50, 50);
    jobListT.setLayoutParams(params);
