Ripple Effect in Android Recycler View is not working

I'm trying to add a ripple effect for the entire row (like we see in listview) in my Recycler View when the row is clicked.
I have tried
android:background="?android:attr/selectableItemBackground"
android:clickable="true"
android:focusable="true"
But still, I couldn't get the desired behavior. Even I have tried
android:foreground="?android:attr/selectableItemBackground"
But still no improvement
My listrow.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="horizontal"
android:background="?android:attr/selectableItemBackground"
android:clickable="true"
android:focusable="true">
<RadioButton
android:id="#+id/radioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/heading"
android:text="Title"
android:textSize="20dp"
android:paddingTop="5dp"
android:textStyle="bold"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:layout_toLeftOf="#+id/subHeading"
android:id="#+id/size"
android:text="Sub Title"
android:paddingTop="3dp"
android:paddingLeft="5dp"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
And My layout with Recycler View
<?xml version="1.0" encoding="utf-8"?>

Here is my adapter source code
private class listAdapter extends RecyclerView.Adapter<ViewHolder> {
private final int mItemCount;
final ArrayList<String> mTitles;
final ArrayList<String> msTitles;
ArrayList<RadioButton> radioButtons=new ArrayList<>();
listAdapter(int itemCount, ArrayList<String> titles, ArrayList<String> sTitles) {
mItemCount = itemCount;
mtitles=titles;
msTitles=sTitles;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
return new ViewHolder(LayoutInflater.from(parent.getContext()), parent);
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
holder.sTitle.setTag(position);
holder.radioButton.setTag(position);
holder.title.setTag(position);
holder.title.setText(mTitles.get(position));
holder.sTitle.setText(msTitles.get(position));
View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
ItemCheckChanged(v);
}
};
holder.radioButton.setOnClickListener(listener);
holder.sTitle.setOnClickListener(listener);
holder.title.setOnClickListener(listener);
if(radioButtons.size()==0){
holder.radioButton.setChecked(true);
selectedItem=0;
}
radioButtons.add(holder.radioButton);
}
#Override
public int getItemCount() {
return mItemCount;
}
void ItemCheckChanged(View v){
selectedItem=(int)v.getTag();
for(RadioButton radioButton:radioButtons){
radioButton.setChecked(false);
}
radioButtons.get(selectedItem).setChecked(true);
notifyDataSetChanged();
}
public int getSelectedIndex(){
return selectedItem;
}
}
NOTE: I'm using these all things in BottomSheetDialog may it be reason?

You should set background to views that have set a click listener.
If you want to set the listener to the whole row you need to call only:
holder.itemView.setOnclickListener() and remove rest of them.

Why Custom ArrayAdapter not showing TextView in a ListView

I have made a custom ArrayAdapter and tried to add the another TextView "Breed" of the animals, but when i execute the program , its not showing the Breed. Where am i doing wrong ? I am scratching my head since long. please help where is the mistake ?
MainActivity.Java
public class MainActivity extends AppCompatActivity {
ListView simpleList;
ArrayList<Item> animalList=new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
simpleList = (ListView) findViewById(R.id.simpleListView);
animalList.add(new Item("Lion",R.drawable.lion,"Khatarnak"));
animalList.add(new Item("Tiger",R.drawable.tiger,"Fudu"));
animalList.add(new Item("Monkey",R.drawable.monkey,"Lallu"));
animalList.add(new Item("Elephant",R.drawable.elephant,"Jabardast"));
animalList.add(new Item("Dog",R.drawable.dog,"ItemDog"));
animalList.add(new Item("Cat",R.drawable.cat,"MeeMee"));
MyAdapter myAdapter=new MyAdapter(this,R.layout.list_view_items,animalList);
simpleList.setAdapter(myAdapter);
}
}
MyAdapter.Java
public class MyAdapter extends ArrayAdapter<Item> {
ArrayList<Item> animalList = new ArrayList<>();

TextView breedView = (TextView)v.findViewById(R.id.breed);
textView.setText(animalList.get(position).getAnimalName());
imageView.setImageResource(animalList.get(position).getAnimalImage());
breedView.setText(animalList.get(position).getBreed());
return v;
}
}

this.breedName = breedName;
}
public Item(String animalName,int animalImage,String breedName)
{
this.animalImage=animalImage;
this.animalName=animalName;

This is most likely a problem with the linear layout for each item. The orientation is horizontal, which lays each view one after the other horizontally. The problem is that the text view for the animal type has a width of fill_parent leaving no space for the breed view. If you change it to wrap_content it'll probably work for some of the cases, but might not work with everything.
In any case I think this is a problem with the views' positions and sizes. Try and move them around. Perhaps even a simple change would be placing them vertically:
<?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="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/imageView"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="5dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Demo"
android:textColor="#000" />
<TextView
android:id="#+id/breed"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Breed"
android:textColor="#000" />
</LinearLayout>
</LinearLayout>
There's perhaps a more efficient way of doing this, but this is just an example. The inner linear layout places one text view on to of the other.
PS: your getCount method is not really doing anything. You can remove it.

replace your layout with my code your issue will resolve.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Android whitespace in imageview

I am using a ViewPager to load images from server using Picasso. I see whitespace below the actual image. When I swipe the area with whitespace the image is swiped.
I have set scaleType="fitXy" to stretch to the ImageView's size.Below is the xml layout and code.
Please dont mark it as duplicate.I have googled it and the solutions did not help me.
#dimen/viewpager_img=150dp in w320dp-xhdpi

}
#Override
public int getCount() {
Log.e("Count",Integer.toString(count));
return count;
}
#Override

linearLayout=(LinearLayout) view.findViewById(R.id.pgr_lyt);
imageView=(ImageView) view.findViewById(R.id.image1);
if (category.equalsIgnoreCase("Ambulance"))
{
count= ambulanceDisplayData.getInstance().imagecount();
images =ambulanceDisplayData.getInstance().getArrayList();
if(count!=0)
{
Log.e("Images", (String) images.get(position));
Picasso.with(context).load("http://abcd.com/xyz/"+(String) images.get(position))
.placeholder(R.drawable.noimage)
.fit().into(imageView);
}
}
container.addView(view);
return view;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View)object);
}
#Override
public boolean isViewFromObject(View view, Object object) {
if(view==object){
return true;
}
else {
return false;
}
}}

You should Set match_parent .
Hard-Coded Value causing problem here .
MATCH_PARENT means that the view wants to be as big as its parent,
minus the parent's padding .
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/image1"
android:adjustViewBounds="true"
android:scaleType="fitXY"
/>

Add android:adjustViewBounds="true" like
<ImageView
android:layout_width="match_parent"
android:layout_height="#dimen/viewpager_img"
android:id="#+id/image1"
android:adjustViewBounds="true"
android:scaleType="fitXY"
/>

Two views with different heights in a viewflipper on a gridview tile

I have a GridView which has a ViewFlipper in each tile. Each view in the ViewFlipper has a different size, but when the tile is flipped, both views are forced to the same size as the GridView column. What i've tried:
Googled
Set android:measureAllChildren to false on ViewFlipper(only works with ListView)
Left android:columnWidth unspecified
Made ViewFlipper root tag in grid tile layout file

}else {
AnimationFactory.flipTransition(flipper, AnimationFactory.FlipDirection.LEFT_RIGHT, 200);
}
}
});
return view;
}
}

Managed to achieve the same grid-style layout with my intented ViewFlipper effect using a StaggeredGridLayoutManager and a RecyclerView.

In Main RelativeLayout contain ViewFlipper, you set height and width!
set them "wrap_content"
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
maybe worked.
good luck.
Update
Use this library:

Swipe Image with button and fingers

I'm trying to do a custom gallery with images shown in fullscreen mode and be able to swipe between different images with Previous Next buttons and with fingers.So for now I did the part with changing images with fingers,but I had to redesign my xml file and the whole structure and logic of my code and I need a little help or suggestions of how to add the new stuff.So the old code which I was using to swipe images with fingers was like this :
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
HorizontalPager realViewSwitcher = new HorizontalPager(getApplicationContext());
ImageView img1 = new ImageView(getApplicationContext());
ImageView img2 = new ImageView(getApplicationContext());
ImageView img3 = new ImageView(getApplicationContext());
ImageView img4 = new ImageView(getApplicationContext());
ImageView img5 = new ImageView(getApplicationContext());
ImageView img6 = new ImageView(getApplicationContext());
img1.setImageResource(R.drawable.one);
img2.setImageResource(R.drawable.two);
img3.setImageResource(R.drawable.three);
img4.setImageResource(R.drawable.four);
img5.setImageResource(R.drawable.five);
img6.setImageResource(R.drawable.six);
realViewSwitcher.addView(img1);
realViewSwitcher.addView(img2);
realViewSwitcher.addView(img3);
realViewSwitcher.addView(img4);
realViewSwitcher.addView(img5);
realViewSwitcher.addView(img6);
setContentView(realViewSwitcher);
And this code shows the image in fullscreen mode and I can swipe between them.Now I need to do something like this :
I want to be able to swipe images with buttons and finger.And my second question is how can I hide the bar in top (Back,Galler,Info) and the bar in bottom (Previous,Next) and show the image in Fullscreen mode and still be able to swipe images only with fingers.
Here is how my xml file looks :
<?xml version="1.0" encoding="utf-8"?>

Thanks in advance!!! Any help,suggestions or links with example are welcomed!

Use the view Flow project to do this. your code with adding imageViews is not a good solution at all.
see viewFlow on gitHub. there are examples with images also. all you do is add this layout in the activity, make an image adapter and thats it.

I did something like this a while back, basically a finger swipe left or finger swipe right perform 2 different actions and there are buttons for the same actions that can be clicked.
In my Main Activity I register the finger swipe listener:
gestureDetector = new GestureDetector(new ListItemGestureDetector(this));
gestureListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if (gestureDetector.onTouchEvent(event)) {
return true;
}
return false;
}
};
Then in my Efficient Adapter that renders my list view, I register the buttons and their click (this would not be the same for you but when adding the buttons to my layout I do this (call and sms being buttons in my layout)
static class ViewHolder {
TextView name, phone;
ImageButton call, sms, other;
//ImageView icon;
}
ViewHolder holder = new ViewHolder();
holder.call.setClickable(true);
holder.call.setFocusable(true);
holder.call.setTag("call");
final int pos = position;
holder.call.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Toast.makeText(context, "CALL", Toast.LENGTH_SHORT).show();
Cursor c = (Cursor) getItem(pos);
Intent i = new Intent(Intent.ACTION_CALL);
String phoneNumber = c.getString(WaddleAddressBook.DATA_ID);
i.setData(Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, phoneNumber));
context.startActivity(i);
}
});

For Swiping images we can simply use ViewPager concept.
1.set the viewpager in your layout
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
2.MyMain.java
public class MyMain extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
ImagePagerAdapter adapter = new ImagePagerAdapter();
viewPager.setAdapter(adapter);
}
private class ImagePagerAdapter extends PagerAdapter {
private int[] mImages = new int[] {
R.drawable.one,
R.drawable.two,
R.drawable.hree,
R.drawable.four
};
#Override
public int getCount() {
return mImages.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
Context context = MyMain.this;
ImageView imageView = new ImageView(context);
int padding =context.getResources().
getDimensionPixelSize(R.dimen.padding_medium);
imageView.setPadding(padding, padding, padding, padding);
imageView.setScaleType(ImageView.ScaleType.CENTER);
imageView.setImageResource(mImages[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}
}
