I am always confused to write the code for fragment because the usual code i get/learn from (eg:youtube) are written for activity instead of fragment.
really appreciate some help. thank you.

so, in a simple way : I want to set video view progress like seekbar progress with any way that I move the seek bar with.
(now it's just works when click on it and when handle and move it , nothing works again).
thanks...

It's finally has been done with that :
SeekBar.OnSeekBarChangeListener onSeekBarChangeListener = new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int i, boolean b) {
if (b) {
videoView.seekTo(i * 1000);
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
handler.removeCallbacks(updateSeekBar);
pause();
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
videoView.seekTo(seekBar.getProgress()*1000);
play();
updateSeekBarProgress();
}
};

Why is the dialog design inconsistent on the device?

I designed dialog and assigned it a file named XML layout with a set of elements and then created a function to show it from within fragment. It appeared on the emulator screen well but it did not appear the same on the device.
What are the appropriate adjustments to be shown on the device well?

android recyclerview show data only at first time

I have a problem ,I create recyclerview and its work fine at the first search data from api , it display fine but when I try to search with new data ( second time ) it is not display anything i try to test and debug every every thing work fine and new data enter to adapter and get the result fine and set adapter to recyclerview but it is not showing any thing
I try several method like use only one adapter and change it's list of Date and use notifyDataSetChange but not work still only show at the first time

Try to create an adapter once and then update items
Add next code to your adapter class
ArrayList<DeliveryReportResource> listDeliveryReport = new ArrayList<DeliveryReportResource>();
public DeliveryReportAdapter(Context context) {
this.context = context;
}
public void updateItems(List<DeliveryReportResource> list) {
listDeliveryReport.clear();
listDeliveryReport.addAll(list);
notifyDataSetChanged();
}
Then create adapter once in onCreate() and place it as global variable
And now you should call adapter.updateItems(...) every time you want to change data

RecyclerView Item Click Listener

I'm trying to replace a ListView with a RecyclerView. The click listeners I had set up for it look like this (this is from the Activity):
//Road Trip selection
roadTripList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
RoadTrip trip = trips.get(i);
Intent intent= new Intent(RoadTripListActivity.this, RoadTripActivity.class);
intent.putExtra("startLocation", trip.getStart());
intent.putExtra("endLocation", trip.getEnd());
intent.putExtra("routeType", trip.getType());
setResult(RoadTripActivity.ROADTRIP_LIST_INTENT_RESULT, intent);
finish();
overridePendingTransition(R.anim.in_right, R.anim.out_left);
}
});
//Road Trip deletion
roadTripList.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> adapterView, View view, final int i, long l) {
new AlertDialog.Builder(RoadTripListActivity.this)
.setTitle("Delete this Road Trip?")
.setMessage("Are you sure you want to delete this road trip from your saved trips?")
.setCancelable(true)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
trips.remove(i);
tripStrings.remove(i);
tinyDB.putListString("roadtrips", tripStrings);
//roadTripList.setAdapter(adapter);
adapter.updateAdapter(trips);
}
}).setNegativeButton("Cancel", null)
.create().show();
return true;
}
});
Adapter looks like this:
public class RoadTripListAdapter extends RecyclerView.Adapter<RoadTripListAdapter.ViewHolder> {
protected ArrayList<RoadTrip> trips;
protected Context context;
public RoadTripListAdapter(Context context, ArrayList<RoadTrip> trips) {
this.context = context;
this.trips = trips;
}
public static class ViewHolder extends RecyclerView.ViewHolder {
private final TextView startTextView;
private final TextView endTextView;
private final ImageView imageView;
private final LinearLayout itemLayout;
public ViewHolder(View v) {
super(v);
startTextView = (TextView) v.findViewById(R.id.roadtrip_list_start);
endTextView = (TextView) v.findViewById(R.id.roadtrip_list_end);
imageView = (ImageView) v.findViewById(R.id.roadtrip_list_icon);
itemLayout = (LinearLayout) v.findViewById(R.id.roadtrip_list_item_layout);
}
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
//Get the corresponding step
final RoadTrip trip = trips.get(position);
holder.startTextView.setText(trip.getStart());
holder.endTextView.setText(trip.getEnd());
if (trip.getType().equals(SearchType.walking.name())) {
holder.imageView.setImageDrawable(ContextCompat.getDrawable(context, R.drawable.ic_directions_walk_24dp));
} else {
holder.imageView.setImageDrawable(ContextCompat.getDrawable(context, R.drawable.ic_directions_car_24dp));
}
}
#Override
public int getItemCount() {
return trips.size();
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.road_trip_list_item, parent, false);
return new ViewHolder(v);
}
public void updateAdapter(ArrayList<RoadTrip> trips) {
this.trips = trips;
this.notifyDataSetChanged();
}
}
And the list item xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/roadtrip_list_item_layout"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/roadtrip_list_icon"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="center_vertical"
android:layout_margin="5dp"
android:src="#drawable/ic_directions_car_24dp"/>
<LinearLayout
android:layout_width="wrap_content"
android:orientation="vertical"
android:layout_height="wrap_content">
<TextView
android:id="#+id/roadtrip_list_start"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:textColor="#color/black"
android:text="Start: "/>
<TextView
android:id="#+id/roadtrip_list_end"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:textColor="#color/black"
android:text="End: "/>
</LinearLayout>
</LinearLayout>
How can I set up the equivalent for a RecyclerView? Everything I can find on the subject says to set it up inside the adapter, but that won't work in this case... Is there a way to set it up in the Activity?

In onBindViewHolder, add OnClickListener and OnLongClickListener like this :
itemLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RoadTrip trip = trips.get(position);
Intent intent= new Intent(RoadTripListActivity.this, RoadTripActivity.class);
intent.putExtra("startLocation", trip.getStart());
intent.putExtra("endLocation", trip.getEnd());
intent.putExtra("routeType", trip.getType());
setResult(RoadTripActivity.ROADTRIP_LIST_INTENT_RESULT, intent);
finish();
overridePendingTransition(R.anim.in_right, R.anim.out_left);
}
});
//Road Trip deletion
itemLayout.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
new AlertDialog.Builder(RoadTripListActivity.this)
.setTitle("Delete this Road Trip?")
.setMessage("Are you sure you want to delete this road trip from your saved trips?")
.setCancelable(true)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
trips.remove(position);
tripStrings.remove(position);
tinyDB.putListString("roadtrips", tripStrings);
notifyItemRemoved(position);
notifyItemRangeChanged(position, trips.size());
}
}).setNegativeButton("Cancel", null)
.create().show();
return true;
}
});

I figured it out:
((Activity) context).setResult(RoadTripActivity.ROADTRIP_LIST_INTENT_RESULT, intent);
((Activity) context).finish();
((Activity) context).overridePendingTransition(R.anim.in_right, R.anim.out_left);
I had been using getApplicationContext to pass as the context for the adapter, so I changed it to
adapter = new RoadTripListAdapter(this, trips);
in the activity.
