Try to use RelativeLayout instead of LinearLayout like below:
<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"
tools:context=".MainActivity">
<fragment
android:name="androidx.navigation.fragment.NavHostFragment"
... />
<com.google.android.material.bottomnavigation.BottomNavigationView
...
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</RelativeLayout>

The fragment in your activity_main has android:layout_height="match_parent" and LinearLayout has vertical orientation. This means that your fragment takes all the place on the screen and your bottom navigation menu placed below your fragment. Also, you shouldn't set navigation menu height as match_parent. I suggest you to try to use ConstraintLayout as layout root.
NOTE! I use AndroidX, but it also works for AppCompat.
<androidx.constraintlayout.widget.ConstraintLayout 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">
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottomNavigationView"
android:layout_width="match_parent"
android:layout_height="#dimen/bottom_menu_height"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:menu="#menu/navigation" />
<fragment
android:id="#+id/fragment"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/bottomNavigationView"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>

I am new in Android, and I have searched a lot about it. But every tutorial I get they do this with main activity, model,adapter. But I have to do it on my home fragment in main activity.

Actually I don't understand your question. If you want to learn about recyclerview and card view and bottom navigation view, follow this tutorial:
https://www.androidhive.info/2016/01/android-working-with-recycler-view/
https://www.androidhive.info/2017/12/android-working-with-bottom-navigation/
It's very easy. If you want to set scroll horizontal use LinearLayoutManager like this
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
RecyclerView myRecyclerView= (RecyclerView) findViewById(R.id.my_recycler_view);
myRecyclerView.setLayoutManager(layoutManager);

videoview not showing on device nor xml design,

I am new in java and xml programming, i am making tabbed activity with fragment, there is no error when running or debug the code but VideoView is not showing, i am using Android Studio,
the idea is i want to make tabbed activity, with textView and videoview in fragment as a content that scrollable(possible ?),one more thing is the API level somehow have influence ? my phone still on KitKat
here is the (fragment) code :
package com.panduanberwudhu;
import android.net.Uri;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.MediaController;
import android.widget.VideoView;
public class MencuciTangan extends Fragment {
private VideoView player;
private String videopath;
private MediaController mediacon;
public View rootView;
//#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.mencucitangan_layout, container, false);
mediacon = new MediaController(getActivity());
player = (VideoView) rootView.findViewById(R.id.videoplayer);
videopath = "android.resource://" + getActivity().getPackageName() + "/" + R.raw.washhand;
player.setVideoURI(Uri.parse(videopath));
player.setMediaController(mediacon);
mediacon.setAnchorView(player);
player.start();
return rootView;
//return inflater.inflate(R.layout.mencucitangan_layout,container,false);
}
}
and the layout code :
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/mencucitangan_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.panduanberwudhu.MencuciTangan">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
/>
<VideoView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/videoplayer"
android:layout_gravity="bottom"
/>
</LinearLayout>
</ScrollView>

Use this layout, where the height Relativelayout is wrap_content which will increase/wrap according to content because it is inside the ScrollView .
I removed Linearlayout as hard coded some value:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/mencucitangan_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:id="#+id/ap"
android:textSize="20sp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<VideoView
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_marginTop="50dp"
android:foregroundGravity="center"
android:id="#+id/videoplayer" />
</RelativeLayout>
</ScrollView>

The error is in the main XML file.
You root is
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
But then the first child have the height fill_parent this makes the first child take all the space of the LinearLayout so when you try to put your fragment in the container, it wont appear in the screen.
Instead try this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Try to get used to use match_parent instead of fill_parent :)

ImageViewTouch doesn't display image on DialogFragment

I've found out the ImageViewTouch since I wanted to create a zooming image preview on my app though I need to display that image on one of my DialogFragment. But it works just fine on a normal FragmentActivity which is the MainActivity but not in my DialogImage and I'm not sure why.
I imported the library using the gradle and here's my code so far:
The MainActivity
import it.sephiroth.android.library.imagezoom.ImageViewTouch;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.widget.Button;
public class MainActivity extends FragmentActivity {
ImageViewTouch mImage;
#Override
protected void onCreate( Bundle savedInstanceState ) {
super.onCreate( savedInstanceState );
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView( R.layout.fragment_main );
mImage = (ImageViewTouch) findViewById( R.id.image );
ImageDownloader2 imgDownload = new ImageDownloader2();
imgDownload.download("MY_URL", mImage);
Button click = (Button)findViewById(R.id.button);
click.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
showPromoImage();
}
});
}
private void showPromoImage(){
DialogImage promo_details = new DialogImage();
promo_details.show(getFragmentManager(), "promo_details");
}
}
The DialogImage
import android.app.DialogFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import it.sephiroth.android.library.imagezoom.ImageViewTouch;
/**
* Created by Bahay on 2/19/14.
*/
public class DialogImage extends DialogFragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.dialog_image, container);
getDialog().setTitle("Test");
getDialog().setCanceledOnTouchOutside(true);
ImageViewTouch promo = (ImageViewTouch) view.findViewById(R.id.image);
ImageDownloader2 imgDownload = new ImageDownloader2();
imgDownload.download("MY_URL", promo);
return view;
}
}

The ImageDownloader2 is just a library which downloads the image from the URL then convert it into bitmap. I just made some customizations for this to work with ImageViewTouch.
As for the ImageViewTouch you can see it here:
https://github.com/sephiroth74/ImageViewZoom
For the ImageDownloader2 class you can see it here:

I just replaced the ImageView with ImageViewTouch for the download method.
UPDATE:
Tried using a normal old-school dialog wherein I use Activity and Intent where I just themed the DialogImage as android:theme="#android:style/Theme.DeviceDefault.Dialog". Output is same where image is not loaded.
Hope someone can help. Thanks!
