Fragment not displaying the whole recyclerview. Its displaying only one cardview

The fragment only displays one cardview when I am trying to retrieve it from the news API.
Here is the code.

Please help me with this, I am unable to find whats wrong here.

Creating multiple button counters in ListView in TabActivity

I'm trying to make an app to keep score during a game of golf. To do this I have 18 tabs in a tab activity (one for each hole) and then in each tab I have a ListView with a list of players, their score for the hole, and a plus and minus button.
I need to make it so that hitting the plus button in a row increases that players score for that hole but I'm having trouble figuring out where and how to do an OnClickListener and how to handle the indexing for the player and the hole.
I'm very new to Android Studio so any help is greatly appreciated!

imageview.setImageResource(id) where id is in your int array. See the documentation for ImageView for details. It is the same as you have in your code just in the onClick() handler.
setImageResource
void setImageResource (int resId)
Sets a drawable as the content of this ImageView.
This does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup. If that's a concern, consider using setImageDrawable(android.graphics.drawable.Drawable) or setImageBitmap(android.graphics.Bitmap) and BitmapFactory instead.

Hi everyone thanks for the help. I solved it by using view page adapter. Every onclick button I will change the adapter. Thank you!!

I have made a ListView with a DialogFragment and I am trying to display this in full screen.
However, when I run it on a device, there is always a border around the edges of the ListView, like a box within a box and cant seem to set it to fill the screen!
I have tried many routes to make this ListView cover the entire screen to no avail.
I would really like and appreciate some help with this.

I think that you should use a FrameLayout in your main_activity layout. Something like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Show"
android:id="#+id/button1"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:onClick="setContentView" />
</FrameLayout>
</RelativeLayout>
Then, in your MainActivity, try this:
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends FragmentActivity {
Button showBtn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final android.support.v4.app.FragmentManager fm = getSupportFragmentManager();
final PlayersFragment p = new PlayersFragment();
showBtn = (Button) findViewById(R.id.button1);
showBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
final FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
showBtn.setVisibility(View.GONE);
transaction.replace(R.id.fragment_container, p);
transaction.addToBackStack(null);
transaction.commit();
}
});
}
#Override
public void onBackPressed() {
if (showBtn != null) {
showBtn.setVisibility(View.VISIBLE);
}
super.onBackPressed();
}
}
Your adapter:
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class Adapter extends ArrayAdapter<String>{
Context c;
String[] players;
int[] images;
LayoutInflater inflater;
public Adapter(Context context, String[] players, int[] images) {
super(context, R.layout.simplerow,players);
this.c=context;
this.players = players;
this.images = images;
}
#Override
public View getView(int position,View convertView, ViewGroup parent){
if(convertView==null)
{
inflater= (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.simplerow,null);
}
TextView nameTv = (TextView) convertView.findViewById(R.id.nameTv);
ImageView img = (ImageView) convertView.findViewById(R.id.imageView1);
nameTv.setText(players[position]);
img.setImageResource(images[position]);
return convertView;
}
}
Your dialog layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
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="Soccer SuperStars"
android:layout_gravity="center"/>
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:background="#android:color/black"/>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/listView1"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
></ListView>
</LinearLayout>
And your PlayerFragment:
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.Toast;
public class PlayersFragment extends android.support.v4.app.DialogFragment {
ListView lv;
String[] players = {"micheal arteta", "deago costa", "andy reid", "scum degea", "scum rooney", "john terry"};
int[] images = {R.drawable.arteta, R.drawable.costa, R.drawable.reid, R.drawable.degea,
R.drawable.rooney, R.drawable.terry};
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.dialog, container, false);
//initialize listview
lv = (ListView) rootView.findViewById(R.id.listView1);
//create adapter obj and set list view to it
Adapter adapter = new Adapter(getActivity(), players, images);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> a, View v, int pos, long id) {
Toast.makeText(getActivity(), players[pos], Toast.LENGTH_SHORT).show();
}
});
return rootView;
}
}
I removed some come (paddings) from your main_activity layout and included some code show the "dialog" (that is now a fragment) full screen.

1) First method
public class PlayersFragment extends DialogFragment {
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme_NoTitleBar_Fullscreen);
}
}
2) Second method
public class PlayersFragment extends DialogFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_TITLE, R.style.myCustomStyle);
}
}
in values add style
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
</style>
<style name="GalleryDialogStyle" parent="AppTheme">
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">#null</item>
</style>
</resources>

Page curl animation to flip between views of a viewflipper

I've come across several examples of the page curl animation as well as viewflippers . Is it possible to navigate between children of a viewflipper via a page curl animation . The animations i have applied to viewflippers till now were very basic such as a slide-in/slide-out and I was wondering if the same could be done/has already be implemented using a page-curl animation.

There is an open source android project here: http://code.google.com/p/android-page-curl/.
I found another one here: https://github.com/harism/android_page_curl/.
But there is no native implementation if that is what you are asking.

You need to import one module library for this, from HERE
After that use following code:-
item_page.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView

android:layout_width="200dp"
android:layout_height="200dp"
android:layout_gravity="center"
android:layout_marginTop="10dp"
android:contentDescription="#string/app_name"
android:scaleType="centerCrop" />
<TextView
android:id="#+id/text"
android:padding="10dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
