Cannot see widgets in tab layout in android studio - java

I am facing the problem of cannot see widgets in tab layouts. I have created textview and button in Overview Fragment but I cannot see them when run code. Is it right to initialize textviews and buttons in oncreateview() of fragment which we don't want to transfer to another tab. I have searched a lot about my problem but cannot get any hint. Code is given below:

TabItem TipsTab = findViewById(R.id.Tipstab);
ViewPager Viewpager1 = findViewById(R.id.viewpagery1);
PagerAdapter pagerAdapter = new PagerAdapter(getSupportFragmentManager(), Tablayout1.getTabCount());
Viewpager1.setAdapter(pagerAdapter);
Tablayout1.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override

For the FabTransformationSheetBehavior to work, you need to change the isExpanded value.
on change of this value, expand and collapse animation will be called and visibility of the linearlayout and fab button will be handled automatically. Don't change visibility manually as this would block transformation animation.
Use back button to transform back to FAB.
val fab: FloatingActionButton = findViewById<FloatingActionButton>(R.id.fab)
fab.setOnClickListener { fab.isExpanded = !fab.isExpanded } // this sets isExpanded as true
val back = findViewById<ImageButton>(R.id.back)
back.setOnClickListener{ fab.isExpanded = !fab.isExpanded } // this sets isExpanded as false

Intro slide helper by viewPager

i wanted to use intro slider to my App
i learned it by this video https://www.youtube.com/watch?v=byLKoPgB7yA&t=22s
I do like video tutorial but I have a problem with dots
when I slide to any page the dots(. ) will be copy and increase
where is my problem and what should I do ?
package time.one.just.show.introslyder;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Html;
import android.widget.LinearLayout;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private ViewPager mSlideViewPager;
private LinearLayout mDotsLayout;
private SlyderAdapter slyderAdapter;
//dots of any Slide pages
private TextView[] mDots;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSlideViewPager = findViewById(R.id.viewPager);
mDotsLayout = findViewById(R.id.dots);
slyderAdapter = new SlyderAdapter(this);
mSlideViewPager.setAdapter(slyderAdapter);
addDotsIndiccator(0);
mSlideViewPager.addOnPageChangeListener(viewListener);
}
private void addDotsIndiccator(int position) {
mDots = new TextView[3];
for (int i = 0; i < mDots.length; i++) {
mDots[i] = new TextView(this);
mDots[i].setText(Html.fromHtml("&#8226"));
mDots[i].setTextSize(35);
mDots[i].setTextColor(getResources().getColor(R.color.colorWhiteNearToGray));
mDotsLayout.addView(mDots[i]);
}
if (mDots.length > 0) {
mDots[position].setTextColor(getResources().getColor(R.color.colorWite));
}
}
ViewPager.OnPageChangeListener viewListener = new ViewPager.OnPageChangeListener() {
#Override
public void onPageScrolled(int i, float v, int i1) {
}
#Override
public void onPageSelected(int i) {
addDotsIndiccator(i);
}
#Override
public void onPageScrollStateChanged(int i) {
}
};}
And this is my SideAdapter class
package time.one.just.show.introslyder;
import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v4.view.PagerAdapter;
import android.view.LayoutInflater;

import android.widget.RelativeLayout;
import android.widget.TextView;
public class SlyderAdapter extends PagerAdapter {
Context context;
LayoutInflater layoutInflater;
public SlyderAdapter(Context context) {
this.context = context;
}
public int[] slide_imagesArray = {
R.drawable.eat,
R.drawable.men,
R.drawable.sleep};
public String[] slide_headerArray = {
"EAT", "men", "code"};
public String[] slide_descriptionArray = {
"this is 1st", "this is 2nd", "this is 3rd"
};
#Override
public int getCount() {
return slide_headerArray.length;
}
#Override
public boolean isViewFromObject(#NonNull View view, #NonNull Object o) {
return view == o;
}
#NonNull
#Override
public Object instantiateItem(#NonNull ViewGroup container, int position) {
layoutInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
View view = layoutInflater.inflate(R.layout.slide_layoout, container, false);
ImageView slideImageView = (ImageView) view.findViewById(R.id.slideImage);
TextView slideheader = (TextView) view.findViewById(R.id.slideheader);
TextView slidedescription = (TextView) view.findViewById(R.id.slideDescription);
slideImageView.setImageResource(slide_imagesArray[position]);
slideheader.setText(slide_headerArray[position]);
slidedescription.setText(slide_descriptionArray[position]);
container.addView(view);
return view;
}
#Override
public void destroyItem(#NonNull ViewGroup container, int position, #NonNull Object object) {
container.removeView((RelativeLayout) object);
}
}
and this is my SliderLayout

I found a solution
just by add this inside my App
mDotsLayout.removeAllViews();
thank you all

Creating Flashcards in Android using Fragments

I am trying to make a simple flash card program where the user selects if they want a addition, subtraction, or multiplication problem and then use a separate fragment to show the flash card. When I run the program it doesn't seem to make it to the first fragment as it just keeps loading in the emulator. What am I doing wrong?

Refresh/update listview current tab

I have three tabs with an unique fragment. How by images:
3 tab and a fragment
First problem is that when I click on "I watch it" on a movie and swipe on Watched's tab, this tab isn't updated.
https://i.imgur.com/AnnN3Zq.png?1
https://i.imgur.com/DsLGn3r.png
After if I swipe/tap on Notify's tab and comeback on Watched's tab, the tab has been updated. Why? Where am I wrong?

Tap Notify's tap (believe also could tap on Suggested) and tap again Watched's tap

For first, you can try adding similar logic to onPageScrolled
Fragment getFragment = getSupportFragmentManager().getFragments().get(position);
if (getFragment instanceof MoviesFragment) {
MoviesFragment thisFragment = (MoviesFragment) getFragment;
if ((position == 0 || position == 2) && positionOffset == 0.0 && positionOffsetPixels == 0)
thisFragment.onRefresh();
}
OK, #user47845 for (This is my list_item_movie.xml) you can try changed to this and tell us how are you doing.

StaggeredGrid RecyclerView not showing anything

I'm trying to inflate a RecyclerView which has as StaggeredGrid Layout, but it is not showing anything. I've pretty much copied previous code I've used before for the RecyclerView so I'm kind of stumped.
In MuseumStoriesViewHolder.onCreateViewHolder() the return of holder has the following value ViewHolder{337ec22b position=-1 id=-1, oldPos=-1, pLpos:-1 unboundundefined adapter position no parent} I'm not sure if this is realated, but it was something that seemed off to me.
It also might help to know that the fragment I'm inflating this RecyclerView is a nested Fragment.
Any help would be greatly appreciated.
