Android studio automatic horizontalscrollview infinite scrolling till end then repeat

Im using android studio , i have xml which have horizontalscrollview
Then linearlayout then multiple imageviews ..
<HorizontalScrollView
android:id="#+id/horizontalScrollView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
</LinearLayout>
What i need is to make this horizantalscrollview to keep automatically infinite scrolling the images till the end then repeat the scrolling again and again.
what i mean by auto scrolling that the horizontalscrollview keep scrolling without using hand

Did you try to use wrap_content in layout_width?
Now, u adapt your width layout to the width of the screen, i think that if u put the value wrap_content it will solve ur problem (u have layout_height=wrap_content, but the height is "asociated" with a Vertical scroll, not with horizontal scroll):
android:layout_width="wrap_content"
I hope this help u.

ok Thanks for your support .. i found the solution
Timer timer1 = new Timer("horizontalScrollViewTimer");
timer1.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
runOnUiThread(new Runnable() {
#Override
public void run() {
if (scrollingLeft) {
if (scroll.getScrollX() == 0) {
scroll.smoothScrollBy(5, 0);
scrollingLeft = false;
} else {
scroll.smoothScrollBy(-5, 0);
}
} else {
if (scroll.canScrollHorizontally(View.FOCUS_RIGHT)) {
scroll.smoothScrollBy(5, 0);
} else {
scroll.smoothScrollBy(-5, 0);
scrollingLeft = true;
}
}
}
});
}
}, 1000, 50);

How to dynamically add suggestions (views) and be able to control the textView in it

I have a fragment in my app that is a basic chatbot. For that chatbot, I want to be able to serve suggestions of replies the user can reply.
I have layout of the reply I want in an xml file.
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical">
<com.google.android.material.card.MaterialCardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="4dp"
android:layout_marginEnd="12dp"
android:layout_marginStart="12dp"
android:layout_gravity="end"
android:padding="4dp"
app:strokeColor="#color/suggestion_border"
app:strokeWidth="2dp"
app:cardElevation="0dp"
app:cardCornerRadius="8dp">
<TextView
android:id="#+id/chat_suggestion"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:textSize="18dp"
android:textColor="#color/chat_text_color"
android:text="Suggestion"/>
</com.google.android.material.card.MaterialCardView>
While produces something like this
and I have a incoming_msg.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/chat_message"
// irrelevent
android:textSize="18sp" />
<TextView
android:id="#+id/chat_time"
// irrelevent
android:text="12:90 PM"
android:textColor="#b4b2b2"
android:textSize="12sp" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/chat_time">
<LinearLayout
android:id="#+id/suggestion_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
</LinearLayout>
</ScrollView>
And because the conversation fragment is a recycler view. I have a onBindViewHolder
public void onBindViewHolder(#NonNull RecyclerView.ViewHolder holder, int position) {
DateFormat df = DateFormat.getTimeInstance(DateFormat.SHORT);
switch (holder.getItemViewType()) {
case 1:
IncomingMsg iM = (IncomingMsg) holder;
iM.msg.setText(msg.get(position).getMessage());
iM.dt.setText(df.format(msg.get(position).getTime()));
if (!msg.get(position).getSuggest().isEmpty()) {
if (iM.s.getChildCount() != msg.get(position).getSuggest().size()) {
for (Suggestion tempSuggestion: msg.get(position).getSuggest()) {
if (tempSuggestion.isWithImage()) {
// TODO
} else {
iM.s.addView(getLayoutInflater().inflate(R.layout.outgoing_suggestion, iM.p));
}
}
}
}
break;
}
}
And at this point, I do not know how to continue, as I couldn't be able to scroll the suggestion list sideway and I couldn't control the text shown in the suggestion.

List page RecyclerView infinite scrolling not working when putted in NestedScrollView

I have taken two recyclerviews as I have to show two lists in which one is horizontal list and another is vertical with infinite scroll, for scrolling of both the lists I have added them in nestedScrollView but infinite scroll of vertical list is not working, there is an pagination logic after first loading of items when I scroll down then api gets called and then it loads items in list
<android.support.v4.widget.NestedScrollView

Reset results and TextUtil

So, I got a feedback from reviewer and fixed most of my problems but there are two problems that I can’t find solution (I will use bold font to highlight them) the first problem comes after I click result button more than one time because the previous result is added. I know that I should add all the methods checkQuestionOne to checkQuestion6 in the button method but this is not possible so far because the method needs (View or view value) which is not working and I don’t know why so I decided not to include the four Radio buttons methods in it. Second when the checkQuestionFive is blank or there is no value the app crashes I was told to use if (!TextUtils.isEmpty(gettingQuestionFive.getText())), then I add Toast message into the if statement but it still crashes. Any help will be appreciated!!
Thank you!

You can see the Logcat and the message error I have. The purpose of this app is to make a quiz app with 3 different inputs (EditText, Radio Buttons, and CheckBoxes). When the EditText is left blank, a crash appears. It seems there is some problem with the onClick attribute in your code but I can figure it out. The second problem comes from clicking the check button more than one time than more points are added to the previous points, I tried to add all the question methods into one and then set the global health variable to 0 but is not really working. Also, take a look of the two pictures below my code.

If you are performing any heavy task on main thread in onCreate() method, that might block the onCreate() UI; to avoid this issue you can run a separate thread for this task.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splace_layout);
mContext = this;
Thread th = new Thread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
try {
mTask();
} catch (Exception e) {
// TODO: handle exception
}
}
});
th.start();
}
