I am trying to create a custom button layout. I created an xml file "custom_button.xml" which I then inflate in the "ButtonLanguageSelection" class. In this class I added the onClickListener. I added this class to the "main_activity.xml". It behaves like it should except it won't receive any touch events. Then I copied the code from "custom_button.xml" and added it directly without inflating it, I just added the android:onClick parameter and in this way it worked. I can't find out what would be the problem, the layouts are the same.
Has some of you have similar problems? What could be the problem? I attached the code if it helps someone to find the problem.
Thank you for any help!

I think the problem is writing all the init code in only one constructor. Consider making an init function and call it from all the constructors. Also consider setting the onClick events listeners in your activity rather than than the layout constructor itself.

I am trying to show a multiline button inside a MaterialButtonToggleGroup but it always shows me ... at the newline
but it works fine outside the MaterialButtonToggleGroup I have tried
using \n and
using <br/> HTML tag with Html.form method
As shown in the image below the first button is outside the MaterialButtonToggleGroup but the second is inside it.

It is an expected result.You can check the source code below where the multiline is overridden.
You can set it programmatically. Something like:
val button : MaterialButton = findViewById(R.id.add_anyone)
button.maxLines = 2
Source code:
https://github.com/material-components/material-components-android/blob/e944d1b2a6ee5d9d5a338de0c0061f7b02790f77/lib/java/com/google/android/material/button/MaterialButtonToggleGroup.java#L751-L754
private void setupButtonChild(#NonNull MaterialButton buttonChild) {
buttonChild.setMaxLines(1);
buttonChild.setEllipsize(TruncateAt.END);
buttonChild.setCheckable(true);
An alternative trick for future reference:
Provide your own custom class, let's name it CustomMaterialButtonToggleGroup, which extends MaterialButtonToogleGroup
example:
public class CustomMaterialButtonToggleGroup extends MaterialButtonToggleGroup {
public CustomMaterialButtonToggleGroup(#NonNull Context context) {
super(context);
}
public CustomMaterialButtonToggleGroup(#NonNull Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
}
public CustomMaterialButtonToggleGroup(#NonNull Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
public void addView(View child, int index, ViewGroup.LayoutParams params) {
super.addView(child, index, params);
if(child instanceof MaterialButton)
{
((MaterialButton) child).setMaxLines(2);
}
}
This way we enforce via code the child views of the MaterialToggleGroup to implement maxLines!
Final the 2nd weird part is:
Go to your Activity/Fragment in which you define your button...and set it via code!
example:
SampleButton.setText("Hey\nI'm multiline"); // notice the escape character of newline-> \n
Afterwards extract it in the strings.xml as you would do normally!
I have my custom BottomSheetDialogFragment.Inside this dialog I have custom edittext and recyclerview.My goal is to move reyclerview above a keyboard,when it' showing. Here is a my custom edittext code
public class WrappedEditText extends android.support.v7.widget.AppCompatEditText {
public WrappedEditText(Context context) {
super(context);
}
public WrappedEditText(Context context, AttributeSet attrs) {
super(context, attrs);
}
public WrappedEditText(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Nullable
private View wrapper;
#Nullable
public View getWrapper() {
return wrapper;
}
#Override
public void getFocusedRect(Rect r) {
if (wrapper != null) {
wrapper.getFocusedRect(r);
return;
}
super.getFocusedRect(r);
}
#Override
public boolean getGlobalVisibleRect(Rect r, Point globalOffset) {
if (wrapper != null)
return wrapper.getGlobalVisibleRect(r, globalOffset);
return super.getGlobalVisibleRect(r, globalOffset);
}
public void setWrapper(#Nullable View wrapper) {
this.wrapper = wrapper;
}
I'm using this code like this
searchView.setWrapper(rootView);
searchView.setOnFocusChangeListener((view1, b) -> {
if(searchView.getWrapper()==null)
searchView.setWrapper(rootView);
});

rootView is a main view in xml file.This code working perfect only first time,but when user closed keyboard and then opened it again ,this code does not working.
Is a any way to solve this problem? or is this a correct solution?
Thanks
I inherited some big project with a lot of legacy code and now I'm facing some weird stuff..
I need to make this screen have recyclerview with grid layout manager, 2 columns. This is what I get. Is there a way to center those icons in the middle of the screen? I tried with gravity, but nothing works. Maybe there is some thing inside all that legacy code that is making problem or this is just recyclerView's issue?
This is the item's layout (terrible, don't ask..)

android:layout_width="match_parent"
android:layout_height="wrap_content"

And the code:
customRecyclerView.setHasFixedSize(false);
customRecyclerView.setLayoutManager(new GridLayoutManager(getContext(), 2));
customRecyclerView.addItemDecoration(new DividerItemDecoration(getContext(),
R.drawable.line_separator_empty, DividerItemDecoration.VERTICAL_LIST));
customRecyclerView.setAdapter(adapter);

}
public CustomRecyclerView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}

}
public void setEnableScroll(boolean enableScroll) {
this.enableScroll = enableScroll;
}
#Override

return super.computeVerticalScrollRange();
}
#Override
public boolean onInterceptTouchEvent(MotionEvent e) {
if (enableScroll) {
return super.onInterceptTouchEvent(e);
}
return false;
}
}
You have to use layout gravity to make it center & need to change match-parent to wrap_content, also you have to assign layout gravity runtime. try this code:

I am writing an app on Android Studio and I am trying to create a custom view with a specific form I need, something like:
Custom View Example
(I used different colors to show how the layout is supposed to go)
Here's the xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="150dp"
android:weightSum="2"
android:background="#android:color/holo_red_dark">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_weight="1"
android:paddingLeft="15dp"
android:paddingRight="15dp">
<TextView
android:layout_width="match_parent"
android:layout_height="75dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text"
android:id="#+id/hourLbl"
android:layout_gravity="center"
android:background="#android:color/holo_blue_bright"/>
<TextView
android:layout_width="match_parent"
android:layout_height="75dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text"
android:id="#+id/minuteLbl"
android:layout_gravity="center"
android:background="#android:color/holo_orange_dark"/>
</LinearLayout>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text"
android:id="#+id/actionName"
android:layout_weight="1"
android:gravity="center"
android:background="#android:color/darker_gray"/>
</LinearLayout>
The problem comes when I try to add this view to another layout in the app.. It comes as a blank square. I have been trying to look for an answer on how to properly do this, but nothing helps.
This is what I have in the xml of the activity where I want the view (ActionView):
<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=".HomeActivity">
<...ActionView
android:layout_width="match_parent"
android:layout_height="150dp"
android:id="#+id/firstAction" />
</RelativeLayout>
Here's the ActionView's constructors I have (not sure what to do with them to be honest, just copied them from a tutorial):
public ActionView(Context context) {
super(context);
}
public ActionView(Context context, AttributeSet attrs) {
super(context, attrs);
TypedArray a = context.getTheme().obtainStyledAttributes(
attrs,
R.styleable.ActionView,
0, 0);
try {
mHourLbl = a.getString(R.styleable.ActionView_hourLbl);
mMinuteLbl = a.getString(R.styleable.ActionView_minuteLbl);
mActionName = a.getString(R.styleable.ActionView_actionName);
} finally {
a.recycle();
}
}
public ActionView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
I think you're missing the most important part. You're not tying your layout to your ActionView object...
Add:
LayoutInflater.from(context).inflate(R.layout.<xml_of_action_view>, this, true);
inside your ActionView constructor.
My Application freezes and LogCat grows heap (frag case) to 14mb if add more then 3 own "components" to current activity/layout. It takes very long until the fourth "component" is added and Android asks to close my application.
I've written a Activity which has some components (EditTexts) and a own "component". I want to do something similar to the contacts app (Number adding) but with ingredients. So I've created a class IngredientsLayout which extends LinearLayout and a Layout xml file with a TextView and a "Add"-Button which I've placed on the Activity-Layout. Every time I press the Add Button, a single IngredientLayout with 3 EditTexts and a ImageButton will be added to the current IngredientsLayout which should "hold" all added ingredients.
What I'm doing wrong?
IngredientsLayout class:
public class IngredientsLayout extends LinearLayout {
ImageButton imageButtonAddIngredient;
ArrayList<IngredientLayout> arrayList;
public IngredientsLayout(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.ingredients_list, this);
arrayList = new ArrayList<IngredientLayout>();
imageButtonAddIngredient = (ImageButton) findViewById(R.id.imageButtonAddIngredient);
imageButtonAddIngredient.setOnClickListener(new OnClickListener() {

LinearLayouts are not meant for this kind of dynamic accessing.
What you need to do is a ListView and a adapter.
And every time you add a new item into the adapter you call it's NottifyDataChanged to update the list view with the new item.
