Scroll View works after opening its fragment for the second time

I have a scrollView in my fragment that only works if I open the fragment once, then close it and then reopen it. At first, it does not scroll at all and after the described steps it works perfectly. I have already tried wrapping the constraintLayout in a tableLayout, LinearLayout, and also used the scrollView as a top level layout. I cannot find anything about this on google.
Please help

Ok so I found the answer.
I used the fragment in a viewpager but it was a custom one.
public class CustomViewPager extends ViewPager {
public CustomViewPager(#NonNull Context context) {
super(context);
}
public CustomViewPager(#NonNull Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int height = 0;
for(int i = 0; i < getChildCount(); i++) {
View child = getChildAt(i);
child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
if(h > height) height = h;
}
if (height != 0) {
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
}
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
After goind back to the normal one, everathing worked again.

Make a class for the dynamic height images.
public class DynamicHeightNetworkImageView extends ImageView {
private float mAspectRatio = 1.5f;
public DynamicHeightNetworkImageView(Context context) {
super(context);
}
public DynamicHeightNetworkImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public DynamicHeightNetworkImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int measuredWidth = getMeasuredWidth();
setMeasuredDimension(measuredWidth, (int) (measuredWidth / mAspectRatio));
}
public void setAspectRatio(float aspectRatio) {
mAspectRatio = aspectRatio;
requestLayout();
}
}
and use it in your xml file
<com.dmitrymalkovich.android.xyzreader.ui.DynamicHeightNetworkImageView
android:id="#+id/thumbnail"
android:layout_width="match_parent"
android:background="#color/material_grey_300"
android:layout_height="wrap_content" />

GridView does not expand

I am kinda new in android and got such a problem, I am trying to use ExpandableHeightGridView for gridview inside scrollview, but layout doesn't render, some advice please.
It always gives me this error:
Exception raised during rendering: ScrollView can host only one direct child
ExpandableHeightGridView.class:
public class ExpandableHeightGridView extends GridView {
boolean expanded = false;

}
public ExpandableHeightGridView(Context context, AttributeSet attrs,
int defStyle)
{
super(context, attrs, defStyle);
}
public boolean isExpanded()
{
return expanded;
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
// HACK! TAKE THAT ANDROID!
if (isExpanded())
{
// Calculate entire height by providing a very large height hint.
// View.MEASURED_SIZE_MASK represents the largest height possible.
int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
}
else
{
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
public void setExpanded(boolean expanded)
{
this.expanded = expanded;
} }

This problem is discussed here.
Try adding one more LinearLayout inside your ScrollView as a direct child and put all other layouts/controls inside of the new LinearLayout.

Gridview elements not getting centered in relativeLayout

android:layout_toRightOf="#id/detail_cplist_item_quality_section"
android:src="#drawable/tag_live"
android:visibility="invisible" />
</RelativeLayout>

Instead of gravity, set this:
android:layout_centerInParent="true"

Had the same problem... I solved it with overridden onMeasure()
public class GridViewEx extends GridView {
private int mRequestedNumColumns = 0;
public GridViewEx(Context context) {
super(context);
}
public GridViewEx(Context context, AttributeSet attrs) {
super(context, attrs);
}
public GridViewEx(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public void setNumColumns(int numColumns) {
super.setNumColumns(numColumns);
if (numColumns != mRequestedNumColumns) {
mRequestedNumColumns = numColumns;
}
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
if (mRequestedNumColumns > 0) {
int width = (mRequestedNumColumns * getColumnWidth())
+ ((mRequestedNumColumns-1) * getHorizontalSpacing())
+ getListPaddingLeft() + getListPaddingRight();
setMeasuredDimension(width, getMeasuredHeight());
}
}
}

I was using
android:layout_below="#+id/msg"
works fine after i removed it and used
android:layout_centerInParent="true"

Use this:
InputMethodManager inputManager = (InputMethodManager) v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);

Wrap your layout inside a ScrollView and you will be able to scroll when the keyboard is shown.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<RelativeLayout
android:id="#+id/top_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"

.......
