In your adapter where you are inflating the item in onCreateViewHolder, is the second parameter of the inflate call null?.
If so change it to parent which is the first parameter in the onCreateViewHolder function signature.
View rootView = LayoutInflater.from(context).inflate(R.layout.itemLayout, parent, false);
If you need the second parameter to be null then when you get the view reference on inflating, do the following
View rootView = LayoutInflater.from(context).inflate(R.layout.itemLayout, null, false);
RecyclerView.LayoutParams lp = new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
rootView.setLayoutParams(lp);
return new RecyclerViewHolder(rootView);
Inside onCreateViewHolder(...) method of adapter where you are inflating the view.. you have to define the ViewGroup as the parent.This you will get from the 1st parameter of onCreateViewHolder(...) method.
see the below line in the second parameter i'm passing the ViewGroup. This will automatically match the view to its parent:
rowView=inflater.inflate(R.layout.home_custom_list, parent,false);
///the complete code is below
public View onCreateViewHolder(ViewGroup parent, int position) {
// TODO Auto-generated method stub
View rowView;
LayoutInflater inflater=(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView=inflater.inflate(R.layout.home_custom_list, parent,false);
I was using a FrameLayout with MATCH_PARENT for width and was seeing the same behavior with a RecyclerView + LinearLayoutManager. None of the above changes worked for me until I did the following in the onCreateViewHolder callback:
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// create a new view
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.note_layout, parent, false);
v.setLayoutParams(new RecyclerView.LayoutParams(
((RecyclerView) parent).getLayoutManager().getWidth(),
context.getResources()
.getDimensionPixelSize(R.dimen.note_item_height)));
return new ViewHolder(v);
}
Clearly looks like a bug in (I'm guessing) the RecyclerView implementation.
try this when you set layout params for your item in adapter.
View viewHolder= LayoutInflater.from(parent.getContext())
.inflate(R.layout.item, parent, false);
viewHolder.setLayoutParams(new RecyclerView.LayoutParams(RecyclerView.LayoutParams.MATCH_PARENT, RecyclerView.LayoutParams.WRAP_CONTENT));
ViewOffersHolder viewOffersHolder = new ViewOffersHolder(viewHolder);
return viewOffersHolder;
I had done fix like this. In my case problem with activity layout file because i am using ConstraintLayout as root activity layout.Might be case for you too.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
android:id="#+id/toolBar"
layout="#layout/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#color/accent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#id/toolBar" />
</android.support.constraint.ConstraintLayout>
This worked for me.
replace this
View view = View.inflate(parent.getContext(), R.layout.row_timeline, null);
return new TimeLineViewHolder(view, viewType);
by this
View rootView = LayoutInflater.from(context).inflate(R.layout.row_timeline, null, false);
RecyclerView.LayoutParams lp = new RecyclerView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
rootView.setLayoutParams(lp);
return new TimeLineViewHolder(rootView, viewType);
In my case, the problem was in RecyclerView XML declaration, the layout_width was 0dp which means match_constraints, when I changed it to match_parent, items started to fill all RecyclerView width:
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="0dp" <-- changed this to "match_parent"
android:layout_height="0dp"
android:layout_marginBottom="45dp"
android:background="#android:color/transparent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHeight_default="wrap"
app:layout_constraintHeight_max="360dp"
app:layout_constraintHeight_min="60dp"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="#id/header"/>
Simply adding a dummy View with 0 height and full width in root worked for me.
<androidx.core.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".screen.gallery.GalleryFragment">
<!----DUMMY VIEW----->
<View
android:layout_width="match_parent"
android:layout_height="0dp"
/>
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/navigationList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
/>
I solved this with:
myInflatedRowLayout.getLayoutParams().width = vg.getWidth();
It is replacing the MATCH_PARENT with the actual width of the RecyclerView.
I was facing the same problem when using Linear layout and constraint layout for my compound view used in recycler view, but it worked when I change to relative layout for those compound views.
I've been stuck with this problem for a while, and the solution that worked for me was placing 2 views with match_parent, one inside the other.
If I did this on my list item's layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#F00"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_height="match_parent">
</RelativeLayout>
although it is a relative layout as others have mentioned, and I am passing the parent view but false in the inflater, it would simply not show up at all (red background to check).
But, when I did this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_height="match_parent">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:background="#0F0"
android:layout_height="match_parent"/>
</RelativeLayout>
The green layout showed up and took up the whole space.
So just having a child view inside the main one with match_parent solves the problem, no idea why.
Can't see your full code, but can guess, that some of the views inside your LinearLayout are 'wrap_content'. You need to make one or some of them expand to the full width by using 'android:layout_weight="1"'
update:
you have a lot of redundant layout_weight's. Make them all 'wrap_content' and for only one of them add layout_weight=1 - for the last CustomTextView. This way, it will occupy all the blank space.
I want to display a picture advertisement at the bottom of the display area. I've tried using bottom but it didn't work. Can you help me?
MainActivity.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include
android:id="#+id/tool_bar"
layout="#layout/tool_bar"
></include>
<LinearLayout
android:id="#+id/adLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_gravity="center_horizontal"
android:orientation="horizontal"></LinearLayout>
<ListView
android:id="#+id/ilcelerListview"
android:layout_width="match_parent"
android:layout_height="wrap_content"></ListView>
</LinearLayout>
Picture link : For Example
I can give your two tip to do that.
You can use RelativeLayout instead of LinearLayout at MainActivity.
For that, you can easy to add a view which you want to add to bottom.
Or
ViewGroup rootView = (ViewGroup) activity.findViewById(Window.ID_ANDROID_CONTENT);
LayoutParams params = new LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT);
//you can use params to set in the bottom or other positions
//view is yours
rootView.addView(view, params);
I have a common layout (common.xml) which I want to include many times in another layout (layout_a.xml). But it only shows me just one time. Why?
common.xml
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#android:drawable/alert_light_frame">
<ImageView
android:layout_width="match_parent"
android:layout_height="150dp"
android:id="#+id/imageView"
android:src="#drawable/test"
android:scaleType="centerCrop" />
<TextView
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_below="#+id/imageView"
android:id="#+id/textView"
android:text="test"
android:layout_marginTop="10dp"
android:layout_marginRight="10dp"
android:layout_marginLeft="10dp" />
</RelativeLayout>
</merge>
layout_a.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/common" />
<include layout="#layout/common" />
</LinearLayout>
The ids when defined in XML must be unique. You are including two layouts that have views that contain the same id.
Here is how you would go about fixing it.
p.s. Unless there is more code that you are not including in your first layout file, that merge tag is useless.
As btse said, the ids in the XML must be unique.
It can be achieved in this way:
<include android:id="#+id/common1"
layout="#layout/common" />
<include android:id="#+id/common2"
layout="#layout/common" />
For information about how to access the elements inside those two included views, you can check out this blog post.
That's what I had done in my Project with Inflater.
test1is just a Layout made with a LinearLayout(Vertical) with text and a button and mainofferslayout in that case, the main layout with an image.
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_offers_display, container, false);
View inflatedLayout = inflater.inflate(R.layout.test1, (ViewGroup) view, false);
LinearLayout ll = (LinearLayout) view.findViewById(R.id.mainofferslayout);
ll.addView(inflater.inflate(R.layout.test1, (ViewGroup) view, false));
ll.addView(inflater.inflate(R.layout.test1, (ViewGroup) view, false));
ll.addView(inflater.inflate(R.layout.test1, (ViewGroup) view, false));
I fixed by setting the layout_height of the RelativeLayout to 250dp since they are overlapped.
In my application I'm adding a view dynamically to the layout using addView.
The added view was inflated beforehand using
andorid:layout_width="match_parent"
however, after the adding the view using
parentView.addView(view, index);
The view is addded but dosen't fill the parent's width
I guess this is because the calculation to the "match_parent" size is done beforehand,
when the view is inflated, and therefore it has no reference of how to set the corect width
is this the case?
is there a way for me to tell the view to recalculate the layout params?
my Code:
activity.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:background="#color/blue_bg">
<ImageView android:id="#+id/myImg"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:src="#drawable/myImg"
android:scaleType="fitXY"/>
<LinearLayout android:id="#+id/addressItemContainer"
android:layout_width="match_parent" android:layout_height="wrap_content"
android:layout_below="#id/myImg" android:layout_marginLeft="10dp"
android:layout_marginRight="10dp">
<View android:id="#+id/placeHolder"
android:layout_width="match_parent" android:layout_height="match_parent"/>
</LinearLayout>
</RelativeLayout>
inserted_view.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="wrap_content" android:background="#drawable/blue_selector">
.... internal views
</LinearLayout>
java code:
LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = li.inflate(R.layout.inserted_view, null);
... fill inserted view fields ...
View aiv = findViewById(R.id.placeHolder);
ViewGroup parent = (ViewGroup) aiv.getParent();
int index = parent.indexOfChild(aiv);
parent.removeView(aiv);
parent.addView(view, index);
Tx for the help :)
Ok, just add this code
View aiv = findViewById(R.id.placeHolder);
aiv.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
Mark as resolved, please.
View view = findViewById(R.id.placeHolder);
view .setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
//addView(view)
Thanks Dmytro Danylyk. Now its work prefectly.
I have this main.xml layout which has a fixed header and footer. The body content has to change based on the parameters received.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="#FFFFFF"
android:id="#+id/main_view">
<com.HeaderView
android:id="#+id/HeaderView"
android:layout_alignParentTop="true"
android:layout_width="fill_parent" android:layout_height="wrap_content" />
<com.FooterView
android:id="#+id/FooterView"
android:layout_alignParentBottom="true" android:layout_width="match_parent"
android:layout_height="wrap_content" />
<RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="#+id/BodyView"
android:layout_below="#id/HeaderView"
android:layout_above="#id/FooterView"/>
</RelativeLayout>
Based on the below conditions I need to load the BodyView in the main.xml.
If parameter == Apple
then load layout AppleView in the BodyView
if parameter == Bat
then load layout BatView in the BodyView
I have AppleView and BatView xml layout defined. Could somebody please guide me as to how I can load either of the views and set/get values into/from it.
Here is an example of inflating, hope this is what you need.
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflater.inflate(R.layout.temp, null);
RelativeLayout rl = (RelativeLayout)findViewById(R.id.glavenfrejm);
RelativeLayout.LayoutParams parametri = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
parametri.addRule(RelativeLayout.ALIGN_PARENT_TOP);
rl.addView(v, parametri);
