White space between each item in recycler view

I'm using Firebase Recycler in my app and I implemented the code in my fragment. The data loads fine but when I scroll to end of list the items gets white spaces between each and that spaces clears only when changed from one activity to other.

Thanks for everyone who tried to answer my question. I just made a small mistake which gave the white spaces between each item.
In the Parent layout of item. I added
android:layout_height:"match_parent"
instead of wrap_content and that made the error.

ScrollView not working with GridLayout in android studio

Hi I want to create a responsive scrollable grids. As I search, I came across some codes. I tweaked this code to allow scrolling of the grids. The code creates a 2 column grids and 4 rows with cardViews. The cardViews shrinks to allow more cards into the viewport rather than scrolling. Am open to any ideas and alternative methods to make this work.Thanks in advance.

I have a pattern like that in one of my apps. Tickets get added to the 3-wide grid and you can scroll the grid. Here is the code I use.
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/your_layout"
android:layout_width="fill_parent"

android:layout_gravity="center_horizontal">
<LinearLayout
android:id="#+id/your_grid"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:gravity="center"
android:orientation="vertical"
android:visibility="visible">

After a lot of research I came across RecyclerView. It was a little confusing but it worked fine. I had to use two(2) layouts (activity_main.xml and row_data.xml) with MainActivity.java.

I watched diff tuts to come up with this. Am now doubting whether it comforms to best practices. Thanks to you all for your suggestions.

Android spinner does not scroll, why?

I have a spinner in my app where you can select categories and sub categories.
It was working perfect in the past but since i did alot of modifications in the app, the spinner does not scroll anymore, not just one spinner, but all spinners in this layout (Drawer menu).
Here's the XML for the right menu drawer that contains the spinner:

This is the spinner adapter:
package com.chno.v1;
import android.app.Activity;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.List;
/**
* List view
*/
public class SpinnerAdapter extends ArrayAdapter<ItemDate> {
private int groupid;
private Activity context;
private ArrayList<ItemDate> list;
private LayoutInflater inflater;
public SpinnerAdapter(Activity context, int groupid, int id, ArrayList<ItemDate> list) {
super(context,id, list);
this.list = list;
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.groupid = groupid;
}
public View getView(int position, View convertView, ViewGroup parent) {
View itemView = inflater.inflate(groupid,parent,false);
ImageView imageView = (ImageView)itemView.findViewById(R.id.img);
ItemDate item = list.get(position);
if(item != null) {
if(item.getType() != null) {
if (item.getType().equals("sub_category")) {
imageView.setVisibility(View.GONE);
} else {
imageView.setImageResource(item.getImageId());
}
} else {
imageView.setImageResource(item.getImageId());
}
} else {
imageView.setImageResource(item.getImageId());
}
imageView.setImageResource(item.getImageId());
TextView textView = (TextView)itemView.findViewById(R.id.txt);
textView.setText(item.getText());
return itemView;
}
public View getDropDownView(int position, View convertView, ViewGroup
parent) {
return getView(position,convertView,parent);
}
}
The thing is i can select items from the spinner but i cannot scroll it down for more items.
Here's the code that populates the spinner:
JSONObject result = config.getCategories();
Iterator<String> iter = result.keys();
while (iter.hasNext()) {
String key = iter.next();
try {
JSONObject cat = result.getJSONObject(key);
String category = cat.getString("n");
int drawable = helper.getCategoryDrawable(Integer.parseInt(key));
Log.e("" + category, "" + key);
list.add(new ItemDate("category", category, Integer.parseInt(key), drawable));
JSONObject subs = cat.getJSONObject("l");
Iterator<String> it2 = subs.keys();
while (it2.hasNext()) {
String sub_key = it2.next();
JSONObject sub_category = subs.getJSONObject(sub_key);
String name = sub_category.getString("n");
Log.e("FFROM LIST", "" + name);
list.add(new ItemDate("sub_category", name, Integer.parseInt(sub_key), Integer.parseInt(key), R.drawable.tool_icon_filter));
}
} catch (JSONException e) {
Log.e("JSONException", e.getMessage());
e.printStackTrace();
}
}
Spinner sp=(Spinner)findViewById(R.id.spinner1);
SpinnerAdapter adapter=new SpinnerAdapter((Activity) context, R.layout.sub_select_item, R.id.txt, list);
sp.setAdapter(adapter);
sp.setFocusable(true);
sp.setFocusableInTouchMode(true);
How can i solve this? Thanks.

How to pass data from bottom sheet to a fragment in android?

I am trying to pass values from a bottom sheet which contains some TextViews to a fragment.
My fragment contains an EditText field and a Floating action button.When the user clicks on the floating action button, the bottom sheet shows up which has a number of TextViews, when the user clicks on any of the textViews on the bottom sheet, the value or the string of that TextView should be displayed in the editText field of the fragment and the bottom sheet should be dismissed.
I have tried implementing the onClickListener inside the setOnShowListener method but it doesn't seem to work.
Here is my code:

As a simple solution you may use LocalBroadcastManager.
public static final String SOME_INTENT_FILTER_NAME = "SOME_INTENT_FILTER_NAME";
In your fragment:
private BroadcastReceiver someBroadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
//TODO extract extras from intent
}
};
#Override
public void onResume() {
super.onResume();
LocalBroadcastManager.getInstance(getContext()).registerReceiver(someBroadcastReceiver,
new IntentFilter(SOME_INTENT_FILTER_NAME));
}
#Override
public void onPause() {
LocalBroadcastManager.getInstance(getContext()).unregisterReceiver(someBroadcastReceiver);
super.onPause();
}
In your bottomsheet:
Intent someIntent = new Intent(SOME_INTENT_FILTER_NAME);
//TODO put extras to your intent
LocalBroadcastManager.getInstance(context).sendBroadcast(someIntent);

code adds one item to listview and then stops

I have the following code that is a dynamic listview where you type in the textbox and click the add button and its added to the listview below. Listview is a custom listview with 2 textviews. Somehow the code adds the first item and then does not add the rest. The arraylist gets the item, i call adapter.notifyDataSetChanged(); and yet still the listview does not get updated. What am i doing wrong?

adapter = new SimpleAdapter (this, list, R.layout.activity_manage_complaints_row, from, to);
lvComplaintsList.setAdapter(adapter);
btnAddComplaint.setOnClickListener(new View.OnClickListener() {

HashMap<String, String> item = new HashMap<String, String>();
item.put("complaint", txtAddComplaint.getText().toString());
item.put("complaintid", Integer.toString(count));
list.add(item);
adapter.notifyDataSetChanged();
count++;
txtAddComplaint.setText("");
Toast.makeText(getApplicationContext(),Integer.toString(list.size()), Toast.LENGTH_SHORT).show();
}
});
lvComplaintsList.setOnItemClickListener(new OnItemClickListener(){

This is the 2 xml files
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical" >
<TableLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="10dip"
android:shrinkColumns="1"
android:stretchColumns="1" >
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/txtAddComplaint"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="3" />
<Button
android:id="#+id/btnAddComplaint"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Add" />
</TableRow>
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/txtComplaintLabel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="List of Complaints : "
android:textAppearance="?android:attr/textAppearanceLarge"
android:paddingBottom="20dp"/>
</TableRow>
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ListView

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_span="2" />
</TableRow>
</TableLayout>
</ScrollView>
</LinearLayout>
This is the listviewrow xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
/>
<TextView
android:id="#+id/lblCID"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"

</RelativeLayout>

As you can see in documentation to SimppleAdapter it is
An easy adapter to map static data to views defined in an XML file.
I believe that you can find any tricky way to add data dynamically. But I'm not sure that you have to do it like this. Try to use ArrayAdapter instead. By default it binds T.toString() values to single TextView, but you can override getView(int, View, ViewGroup) to return the type of view you want.

I changed the main xml file as follows
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/LinearLayout02"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/txtAddComplaint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" >
</EditText>
<Button
android:id="#+id/btnAddComplaint"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add to Listview" >
</Button>
</LinearLayout>
<ListView
android:id="#+id/lvComplaintsList"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
I had used a table layout and the listview was in one of the rows.
Hope this helps someone .
