I am using a RecyclerView and I am not able to see any feedback when I touch on the item of the RecyclerView. How do I achieve it?
I am trying to show a feedback to the user when they are touching the row of RecyclerView. Something like a ripple effect.
I want to know how to achieve it in a specific row of the RecyclerView.
This is the recycler view's custom row layout.
<?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="50dp"
android:id="#+id/drawer_row"
android:background="?android:attr/selectableItemBackground"
android:clickable="true">
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="30dp"
android:layout_marginStart="30dp"
android:layout_toEndOf="#+id/navigation_image"
android:layout_toRightOf="#+id/navigation_image"
android:textSize="17sp" />
<ImageView
android:id="#+id/navigation_image"
android:layout_width="24dp"
android:layout_height="24dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
android:layout_marginLeft="30dp"
android:layout_marginStart="30dp" />
<TextView
android:id="#+id/horizontal_line"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_alignParentBottom="true"
android:background="#F1F1F1" />
</RelativeLayout>
This is the layout of the Activity having the RecyclerView
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/windowBackground">
<RelativeLayout
android:id="#+id/nav_header_container"
android:layout_width="match_parent"
android:layout_height="150dp"
android:layout_alignParentTop="true"
android:background="#drawable/ic_drawer_header">
<ImageView
android:id="#+id/circle_imageview"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:background="#drawable/profile_pic"
android:layout_marginTop="10dp"
android:layout_marginLeft="10dp" />
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="John Doe"
android:textSize="20sp"
android:textColor="#ffffff"
android:layout_below="#+id/circle_imageview"
android:layout_alignLeft="#+id/circle_imageview"
android:layout_alignStart="#+id/circle_imageview"
android:layout_marginTop="5dp" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Transaction Technologies"
android:layout_below="#+id/textView"
android:layout_alignLeft="#+id/textView"
android:layout_alignStart="#+id/textView"
android:textColor="#ffffff"
android:layout_marginTop="5dp" />
</RelativeLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/drawerList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/nav_header_container" />
</RelativeLayout>
I just need to highlight/give feedback of the row which is being touched by the user. How do I achieve it?
Thanks in advance.
You need to add android:focusable="true" in your custom row item for RecyclerView
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:id="#+id/drawer_row"
android:background="?android:selectableItemBackground"
android:focusable="true"
android:clickable="true" >
</RelativeLayout>
You can add a Ripple effect by using THIS LIBRARY.Include it in your Gradle files using.
compile 'com.thomsonreuters:rippledecoratorview:+'
Simply put your row layout in a RippleDecoratorView.For eg:
<com.thomsonreuters.rippledecoratorview.RippleDecoratorView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_margin="4dp"
rdv:rdv_rippleColor="#android:color/holo_blue_dark"
rdv:rdv_rippleAnimationFrames="60"
rdv:rdv_rippleAnimationPeakFrame="15"
rdv:rdv_rippleMaxAlpha="0.8"
rdv:rdv_rippleAnimationDuration="600"
rdv:rdv_rippleRadius="50dp">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:id="#+id/drawer_row"
android:background="?android:attr/selectableItemBackground"
android:clickable="true">
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="30dp"
android:layout_marginStart="30dp"
android:layout_toEndOf="#+id/navigation_image"
android:layout_toRightOf="#+id/navigation_image"
android:textSize="17sp" />
<ImageView
android:id="#+id/navigation_image"
android:layout_width="24dp"
android:layout_height="24dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
android:layout_marginLeft="30dp"
android:layout_marginStart="30dp" />
<TextView
android:id="#+id/horizontal_line"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_alignParentBottom="true"
android:background="#F1F1F1" />
</RelativeLayout>
</com.thomsonreuters.rippledecoratorview.RippleDecoratorView>
Or you can use any of these libs acc to your requirement:
1>https://github.com/balysv/material-ripple
2>https://github.com/siriscac/RippleView
3>https://github.com/traex/RippleEffect
I can help you but I will need some feedback from you as well. In the onCreateVIewHolder inside your recycler View adapter you must have defined textViews and assigned it to the elements inside the sample recycler view. Add this. Make sure you define the layout outside the function so its accessible throughout the class
RelativeLayout layout;
layout=(RelativeLayout)view.findViewById.(R.layout.drawer_row)
Then go to you recycler view adapter and in the onBindViewHolder define
holder.layout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Handle onClick event
}
});
In the onClick event you can add any kind of feedback you want to the user to experience such as starting a new activity, toasts, messages or in this case a ripple effect. You can use a custom library for ripples such as these
Ripple effect for lollipop views
https://android-arsenal.com/details/1/980
https://github.com/balysv/material-ripple
Ripple effects are not supported in pre-Lollipop devices.
Still use this material-ripple
compile 'com.balysv:material-ripple:1.0.2'
Apply ripple on holder.drawView
MaterialRippleLayout.on(holder.drawerView)
.rippleColor(Color.RED)
.create();
Or you can apply from xml
<com.balysv.materialripple.MaterialRippleLayout
android:id="#+id/ripple"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Button inside a ripple"/>
</com.balysv.materialripple.MaterialRippleLayout>

Looking at many examples (mostly the messaging apps like Facebook etc) - I made a LinearLayout which describes all the options (in this case DELETE / EDIT etc along with few other icons) and added it to all items in my RecyclerView. When item in RecyclerView is Tapped and Hold I am making it visible with an animation.
This works fine for the most part but I feel like this is not the right way as each of my RecyclerView item has this LinearLayout attached but just hidden (taking too many resources) and then I am changing the Visibility State to visible or gone in case of Tap and Hold and Sigle Tap respectively.
My RecyclerView Item code is the following
<?xml version="1.0" encoding="utf-8"?>

In android:id="#+id/options_layout" I am hiding it than showing it when user tap and holds But I felt like there are better ways to do this, If I Look at the other apps, it seems like its an overlay on top of while 'Activity' or Fragment as shown in the following screenshot
The above feels more responsive and light-weight. The other way I thought I could do this is to put this options_layout on my MainActivity and call it every time when user Tap and holds an item of RecyclerView but if this is how it is done then the question is how do you align the layout right on top of RecyclerView item as shown in the above screenshot, the option layout opens just at the right potion to the recycler view selected item.
Any idea how is it done?
Ok, I realize this is kind of a strange question but I have no idea what is causing it.
I have created a custom view with a square. I've added a few of those to the activity with defining it in the xml of the activity, so everyone of them has a unique ID. Each of them can be manipulated (change the color of the square) with for example the button click. All was working well until I clicked on some EditText I also had defined in my activity. And for some reason OnDraw() of my custom view fired. All of the custom views defined in that activity were updated with the same color.
I have no idea why this fires when I click the EditText. Any EditText. I have tried adding a new one and it is the same.

This is my layout. Some of the custom view are on other layouts and they too get updated when I click on whichever EditText.
I´m a bit lost.
I´m developping my first Android app, and I´m not sure about the better way to implement some activities.
No my problem is than in my app, I have to divide the screen in two equals parts, one side for each player. Each side has two TextView, some buttons, etc, the same for both player, but one the sides rotated 180 degrees relative to the other.
What would be the better way to do that?
Define a whole layout and repeat the same layout inside for each player? I think this would be the worst solution because the management of the listeners for the views would be duplicated and more complicated.
Use a layout to define the player views and put it in a ListView or Table with two items/rows, using a custom adapter to unify the management of the listeners? In this case I don´t know how to divide the screen in two equals parts and fit the whole screen...
Use fragments, defining a fragment to define the player a put it twice in the layout?
Another idea.....
Could anyone help me and tell me the better way to do that in Android and the better way in terms of management and performance?
Thanks in advance.
I finally decided to use the include tag in my root layout this way:
<LinearLayout 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"
android:padding="10dip"
android:orientation="vertical"
tools:context="com.example.cdp.mispartidas.actividades.Duel">
<include android:id="#+id/player0"
android:layout_gravity="top"
android:rotation="180"
android:layout_weight="1"
android:layout_marginBottom="10dp"
layout="#layout/player_duel"/>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#android:color/holo_blue_dark"/>
<include android:id="#+id/player1"
android:layout_gravity="bottom"
android:layout_weight="1"
android:layout_marginBottom="10dp"
layout="#layout/player_duel"/>
Now my doubt is the better way to manage the listeners. In the "player_duel" layout I have two buttons that modify the content of a TextView, another button for another task, and Dialog that has to appear when click on the TextView, etc.
Now I have all the View duplicated. I can identify then by using the corresponding layout, but how I could unify the event listeners management?
Regards
player_duel.xml
<LinearLayout>
<TextView android:id="#+id/tv_0"/>
<Button android:id="#+id/btn_0"/>
<Button android:id="#+id/btn_1"/>
<Button android:id="#+id/btn_2"/>
</LinearLayout>
OnClickListner listener = new OnClickListener(){
public void onClick(View v){
if(v.getParent()!=null && v.getParent().getId() == R.id.player0){
swicth(v.getId()){
case R.id.tv_0:
break
case R.id.btn_0:
break
case R.id.btn_1:
break
case R.id.btn_2:
break
}
}else if(v.getParent()!=null && v.getParent().getId() == R.id.player1){
......
}
}
};
((ViewGroup)findViewById(R.id.player0)).findViewById(R.id.tv_0).setOnClickListener(listener);

I finally found the solution by defining the two-views array and using the "fake" viewholder. I define a listener for all the common views in the layout, and store the index as property in the constructor, so in the listener I only have to refer the proper item in the array with the index.
I'm not able to make a View that fill the height of a RelativeLayout, which is the layout of ListView items. Here is my layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<View
android:id="#+id/fill_the_height_please"
android:layout_width="15dp"
android:layout_height="match_parent"
android:background="#color/red"/>
<TextView
android:id="#+id/delivery_list_item_dest"
android:layout_width="wrap_content"
android:layout_toRightOf="#id/fill_the_height_please"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:layout_marginTop="2dp"
android:text="Destinatario" />
<TextView
android:id="#+id/delivery_list_item_address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#id/delivery_list_item_dest"
android:layout_below="#id/delivery_list_item_dest"
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:text="Location" />
<ImageButton
android:id="#+id/delivery_list_item_mapBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="0dp"
android:src="#drawable/map_location"
android:background="#null" />
View with id fill_the_height_please not fill the item height. In figure below you can see the result (nothing is shown):
I'd like something like this:
ù
I have also try to change view layout as follows but not works anyway:
<View
android:id="#+id/fill_the_height_please"
android:layout_width="15dp"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentBottom="true"
android:background="#color/red"/>
Please can you help to achieve my goal? Thank you.
One suggestion would be add layout_alignTop="#+id/delivery_list_item_mapBtn" and layout_alignBottom="#+id/delivery_list_item_mapBtn" to the View and make it always fit the image height.
Try changing
android:layout_toRightOf="#id/delivery_list_item_statusBtn"
to
android:layout_toRightOf="#id/fill_the_height_please"
You don't have delivery_list_item_statusBtn. But i see red part even without changing this. Try it and if it doesn't help please post code of your adapter.
Looking here it seems RelativeLayout has a bug in version 17 and lower. So i have change my layout as follows:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<View
android:id="#+id/fill_the_height_please"
android:layout_width="15dp"
android:layout_height="match_parent"
android:background="#color/red"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:orientation="vertical" >
<TextView
android:id="#+id/delivery_list_item_dest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Destinatario"
android:layout_marginBottom="5dp" />
<TextView
android:id="#+id/delivery_list_item_address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Location" />
</LinearLayout>
<ImageButton
android:id="#+id/delivery_list_item_mapBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="0dp"
android:src="#drawable/map_location"
android:background="#null" />
</RelativeLayout>
A little bit more complex but works. However i leave the question unresolved in case someone find a solution using only a RelativeLayout
I'm trying to show a vertical line in an android ListView item. I define it in the XML for the cell but when I preview it in the ListView it doesn't appear.
I understand this is an issue because I see alot of questions on here, but don't see any real answer.
The XML is pretty standard:
Cell:
<?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:background="#color/appWhite" >
<View android:layout_width="5dp"
android:layout_height="match_parent"
android:background="#color/appGreen"
android:layout_alignParentLeft="true" />
<RelativeLayout
android:id="#+id/cell_trip_info_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/vertical_bar" >
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/cell_trip_name"
android:paddingTop="20dp"
android:paddingBottom="20dp"
android:textColor="#2c3e50"
android:paddingLeft="10dp"
android:text="adfadf" />
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/cell_trip_country"
android:layout_below="#+id/cell_trip_name"
android:textColor="#2c3e50"
android:paddingLeft="10dp"
android:text="adfadf" />
</RelativeLayout>
<RelativeLayout android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:id="#+id/whole_container"
android:layout_alignParentRight="true" >
<RelativeLayout android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#color/appGreen"
android:id="#+id/cell_trip_date_box"
android:layout_alignTop="#+id/update_buttons"
android:layout_alignBottom="#+id/update_buttons"
android:padding="20dp" >
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/cell_tripstart_date"
android:layout_centerHorizontal="true"
android:textColor="#fff" />
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/cell_date_thru"
android:text="#string/thru"
android:layout_below="#+id/cell_tripstart_date"
android:layout_centerHorizontal="true"
android:textColor="#fff" />
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/cell_tripend_date"
android:layout_below="#+id/cell_date_thru"
android:textColor="#fff"
android:layout_centerHorizontal="true" />
</RelativeLayout>
<RelativeLayout android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/update_buttons"
android:visibility="gone"
android:layout_toRightOf="#+id/cell_trip_date_box"
android:background="#e9e9e9"
android:padding="20dp" >
<ImageView android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/cell_button_edit_trip"
android:src="#drawable/slide_edit"
android:adjustViewBounds="true"
android:contentDescription="#string/content_description" />
<ImageView android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/cell_button_delete_trip"
android:src="#drawable/slide_delete"
android:layout_toRightOf="#+id/cell_button_edit_trip"
android:adjustViewBounds="true"
android:contentDescription="#string/content_description" />
</RelativeLayout>
</RelativeLayout>
</RelativeLayout>
I found the cause and the obvious solution/workaround on another post Here
Basically RelativeLayouts for whatever reason won't play nice with the "match_parent" height setting in a ListView Item. One of the answer to the post recommended using a LinearLayout instead. So I just created a new File with the parent view being a LinearLayout. I then created a RelativeLayout child and tossed everything else in there.
It worked fine this time, easily allowing me to create my vertical rule.
In your cell_trip_info_container RelativeLayout you have
android:layout_toRightOf="#+id/vertical_bar"
You dont have a View named vertical_bar
Add that ID to your vertical bar view and you should be good to go
<View
android:id="#+id/vertical_bar"
android:layout_width="5dp"
android:layout_height="match_parent"
android:background="#color/appGreen"
android:layout_alignParentLeft="true" />
change
RelativeLayout
to
VerticalLayout
