FrameLayout not displaying elements - java

I am trying to create a FrameLayout that contains other FrameLayouts. I have created an EditorView class that extends FrameLayout, and I want it to display FileView, another class that extends FrameLayout. But in Android Studio preview I get an blank view. What am I doing wrong.
This is the ediorview_activity.xml:
<?xml version="1.0" encoding="utf-8"?>
<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">
<com.itsvaske.webio.Views.LineView
android:id="#+id/html1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<com.itsvaske.webio.Views.LineView
android:id="#+id/html2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/html1" />
<com.itsvaske.webio.Views.LineView
android:id="#+id/html3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/html2" />
<com.itsvaske.webio.Views.LineView
android:id="#+id/html4"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/html3" />
<com.itsvaske.webio.Views.LineView
android:id="#+id/html5"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/html4" />
<com.itsvaske.webio.Views.LineView
android:id="#+id/html6"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/html5" />
<com.itsvaske.webio.Views.LineView
android:id="#+id/html7"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/html6" />
</RelativeLayout>
This is lineview_layout.xml:
<?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">
<TextView
android:id="#+id/lineNumber"
android:layout_width="30dp"
android:layout_height="40dp"
android:layout_weight="0"
android:gravity="center"
android:text="1"
android:textColor="#000000"
android:textSize="20sp" />
<EditText
android:id="#+id/line"
android:layout_width="wrap_content"
android:layout_height="42dp"
android:layout_weight="3"
android:background="#null"
android:ems="10"
android:hint="#string/typeyourline"
android:inputType="textPersonName"
android:minHeight="32dp"
android:textColorHint="#546E7A" />
</LinearLayout>
This is EditorView class:
public class EditorView extends FrameLayout {
private Context mContext;
private AttributeSet mAttributeSet;
public EditorView(#NonNull Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
this.mContext = context;
this.mAttributeSet = attrs;
initView();
}
private void initView() {
View view = View.inflate(mContext, R.layout.editor_start_html_layout, this);
LineView line1 = view.findViewById(R.id.html1);
LineView line2 = view.findViewById(R.id.html2);
LineView line3 = view.findViewById(R.id.html3);
LineView line4 = view.findViewById(R.id.html4);
LineView line5 = view.findViewById(R.id.html5);
LineView line6 = view.findViewById(R.id.html6);
LineView line7 = view.findViewById(R.id.html7);
line1.setLineNumber(1);
line1.setLineContents("<html>");
line2.setLineNumber(2);
line2.setLineContents("<head>");
line3.setLineNumber(3);
line3.setLineContents(" <title></title>");
line4.setLineNumber(4);
line4.setLineContents("</head>");
line5.setLineNumber(5);
line5.setLineContents("<body>");
line6.setLineNumber(6);
line6.setLineContents("</body>");
line7.setLineNumber(7);
line7.setLineContents("</html>");
}
}
And In preview I get this:

Android OnClick on main layout does not work, is it because of MotionLayout?

I want to be able to perform onClickListner on root RelativeLayout called "rl". Not it does not work I suspect it can be because of MotionLayout as a children. How to solve that?
Here is what I have done so far, my code.
ShowNoteActivity.java
(...)
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
(...)
RelativeLayout rl = findViewById(R.id.rl);
rl.setOnClickListener(view -> {
Toast.makeText(this, "abc", Toast.LENGTH_SHORT).show();
});

If you want to click on parent you should disable motionlayout transition and do your transition programmatically with one button or ...
Disable motion layout:
motionLayout.getTransition(R.id.yourTransition).setEnable(false)
If you must to use onSwipe in your project you can disable transition after collapsing motionlayout and return layout to top programmatically and when expand enable motionlayout transition.

TextView not appearing in embedded LinearLayout

I am creating a simple tasklist app, and I want to programmatically add a TextView to an embedded LinearLayout. However, it is not showing up for some reason.
I try to add the TextView in MainActivity (irrelevant code removed).
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
processExtraData();
}
private void processExtraData(){
Integer hours = 4;
Integer minutes = 35;
Integer seconds = 0;
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linlayout);
TextView txt1 = new TextView(this);
final float scale = this.getResources().getDisplayMetrics().density;
int pixels = (int) (64 * scale + 0.5f);
ViewGroup.LayoutParams params = new LinearLayout.LayoutParams(0, pixels, 1f);
txt1.setLayoutParams(params); txt1.setText(hours.toString()+":"+minutes.toString()+":"+seconds.toString());
linearLayout.addView(txt1);
}
The embedded LinearLayout is declared in activity_main:
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/clearButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:text="Clear All" />
</LinearLayout>
I have already tested and made sure that onNewIntent and processExtraData are called. No errors are thrown either. Could this be a GUI issue? Any help would be greatly appreciated.

Unable to make RecyclerView Width as match parent

Recycler View is only occupying 1st half of the screen no matter what I do.
Can anyone suggest how to make Recyclerview occupy full width of the screen?
This is what it displays me in Android Studio
But this is the actual output on a device. It's all wrapped to the left side of the device.

recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager((this)));
recordList = new ArrayList<>();

qty = itemView.findViewById(R.id.qty);
rate = itemView.findViewById(R.id.rate);
total = itemView.findViewById(R.id.total);
}
}
}
I found it:
All I had to change the following line of code in my custom adapter as follows:
View view = inflater.inflate(R.layout.record_logs_card, null);
to
View view = inflater.inflate(R.layout.record_logs_card, parent, false);`

Custom layout not showing

I am trying to make a reusable header. Here is my XML.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/bg" >
<ImageButton
android:id="#+id/imagebuttonforheader"
android:layout_height="50dp"
android:layout_width="50dp"
android:layout_alignParentLeft="true"
android:background="#drawable/back_button"
/>
<ImageButton
android:id="#+id/imagebuttonforheader"
android:layout_height="50dp"
android:layout_width="50dp"
android:layout_alignParentRight="true"
android:background="#drawable/forward_button"
/>
</RelativeLayout>
I made a class for it:
public class Header extends RelativeLayout {
Context context;
Activity activity;
public Header(Context context, AttributeSet attrs) {
super(context, attrs);
this.context = context;
LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
li.inflate(R.layout.header, null, false);
}
}
And then added this layout into my main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<my.testy.view.Header
android:id="#+id/headerOnMain"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" >
</my.testy.view.Header>
<TextView
android:id="#+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/headerOnMain"
android:text="#string/hello" />
</RelativeLayout>
But it's not showing up on the application.
What am I doing wrong here?
You have to attached your inflated layout to your custom class:
li.inflate(R.layout.header, this, true);
