I have my app, it has the following appareance:
The table at the bottom side is a TableLayout.
In my MainActivity.java I am using the following code to populate the whole layout of my app:
setContentView(R.layout.activity_main);
movieCompletionView = (TokenCompletionView)findViewById(R.id.searchMovie);
cineCompletionView = (TokenCompletionView)findViewById(R.id.searchCine);
...
TableLayout tl_Movies = (TableLayout)findViewById(R.id.tableLayoutMovies);
tl_Movies.removeAllViews();
for (...) tl_Movies.addView(someRow);
Then, I googled for some samples to improve the appareance of my table, and I found this:
But this sample builds only the table. In the MainActivity.java the code used for building it :
Table table = new Table(this);
setContentView(table);
And Table class:
public class Table extends LinearLayout {
..
}
Now, what I want is to add the smarter table to the original layout of my app.
I added an empty LinearLayout component in my activity_main.xml and I tried to populate it with this code:
setContentView(R.layout.activity_main);
movieCompletionView = (TokenCompletionView)findViewById(R.id.searchMovie);
cineCompletionView = (TokenCompletionView)findViewById(R.id.searchCine);
...
linearLayout = (LinearLayout) findViewById(R.id.smarterTable);
linearLayout = new Table(this);
But it does not work.
Sorry for the very basic question, but, can you tell me which are the right statements for adding the smarter table to the original layout of my app?
Edit 27-Nov-2017
Following the suggestion on Mike M. and F43nd1r.
I configured my activity_main.xml in this way:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
tools:context="com.myapps.pavel.myseapp.MainActivity">
<com.myapps.pavel.myseapp.Table
android:id="#+id/smarterTable"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"/>
</LinearLayout>
And I used the following code in my MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
linearLayout = (Table) findViewById(R.id.smarterTable);
And I got this error:

Solved!:
as Mike M. says, I had to change the parameters of the Table constructor
public Table(Context context,AttributeSet attrs) {
super(context, attrs);
Instead of <LinearLayout> use <com.your.package.Table> in the xml layout.
Then use the following:
linearLayout = (Table) findViewById(R.id.smarterTable);
for (...) linearLayout.addView(someRow);
Edit regarding your edit
Add this constructor to Table:
public Table(Context context, AttributeSet attrs) {
super(context, attrs);
}

I'm trying to get this effect in my UI: https://github.com/traex/ExpandableLayout.
1) I added to my build.gradle the compile '...' for this library
2) I created workout_main.xml file ( I'll post the code below)
3) I use a fragment which extends a base fragment class ( which is created by my activity). I'm able to use inflate view for other fragment in this activity but this one seems to crash because of the library I'm using. I'm not sure if that would be the culprit or the way I'm approaching things
As an aside, I looked on their GitHub open / closed issues and the only "solutions" to this problem was using android.enableAapt2=false in the gradle.properties file. ( which didn't work)
WORKOUT_MAIN.XML:
<?xml version="1.0" encoding="utf-8"?>

private final static String TAG = WorkoutTabFragment.class.getSimpleName();

#Override

Bundle savedInstanceState) {
//ERRROR HAPPENS HERE
View v = inflater.inflate( R.layout.workout_main, container, false);
expandableListView = (ExpandableListView) v.findViewById(R.id.listview);
/* pre loading stat */
woAdapter = new WorkoutListAdapter(getContext(), workoutList, recentListActionModeUtil);

final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(getContext(), R.layout.view_row, R.id.header_text, array);
expandableListView.setAdapter(arrayAdapter);
return v;
}

I'm unsure as of how to initialise the TextView object in onCreateView, as everything I've tried has produced this same message. Here is my code:
package com.takemeout.android.event;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;
import com.takemeout.android.R;
import java.util.Calendar;
import java.util.List;
public class EventListFragment extends Fragment {
EventOverviewProvider provider = new EventOverviewProvider();
List<EventOverviewProjection> eventsToday = provider.getTodayEvents();
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_event_list, container, false);
//getEventsToday(eventsToday, v);
LinearLayout ll = (LinearLayout) v.findViewById(R.id.fragment_event_list);
TextView text = new TextView(this.getActivity());
text.setText("Sample text");
ll.addView(text);
// Inflate the layout for this fragment
return v;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}
Here is my fragment_event_list.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
</LinearLayout>
Anyone have an idea of what I might be doing wrong?
Your LinearLayout is missing id. Just add android:id="#+id/fragment_event_list to LinearLayout in your xml. But you should choose a better name, something like #+id/list_view
Add the ID: in Xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/fragment_event_list" //add this
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1">
</LinearLayout>
The ID is not added properly. That's why it gives null.
Update your onCreateView method to :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_event_list, container, false);
//getEventsToday(eventsToday, v);
LinearLayout ll = (LinearLayout) v;
TextView text = new TextView(this.getActivity());
text.setText("Sample text");
ll.addView(text);
// Inflate the layout for this fragment
return v;
}
since your parent layout itself is the layout you want to use to add textView, you can just typecast it and you are good to go.
When I am trying to run the code in a real device it gives an error but it works on an emulator.
I think the error is related to the packages.
Here is the error;

Basically, the constructor to AnimationView is creating a Background object. The constructor of Background is trying to create a bitmap that is 103MB large. That's too big. (Something close in size to a 5000x5000 pixel image) You didn't show the code to Background, but it's trying to create a Bitmap or load an image that is too large.
Try scaling your original Bitmap resource to a more manageable size.
I have an application that uses a fragment view as part of its layout. Within this fragment, I want to instantiate a Paint Canvas where i can do custom drawing.
The problem is, my app crashes when I go to inflate the fragment with the error android.view.InflateException: Binary XML file line #15: Binary XML file line #15: Error inflating class com.example.xxxxx.NeckCanvasOverlay
I'm not sure what's causing my Paint class not to inflate properly. I know there are special rules about how you use findViewById inside a fragment, but I thought I was adhering to them since i'm calling findViewByid on the fragment's view itself (called "v" in my code).
How can I fix this issue?
FragmentNeckDisplayMenu.java (Fragment Class)
public class FragmentNeckDisplayMenu extends Fragment {
private static View v;
private NeckCanvasOverlay neckHUD;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
v = inflater.inflate(R.layout.menu_fragment_neck_display,container,false); //ERROR HERE
NeckCanvasOverlay neckHUD = (NeckCanvasOverlay) v.findViewById(R.id.neckHUD); //paint test
...
return v;
}
}
NeckCanvasOverlay.java (Paint Class)
class NeckCanvasOverlay extends View {
private Paint mPainter;
public NeckCanvasOverlay(Context context) {
super(context);
initView();
}
private void initView(){ //Initializes canvas & paint objects here to save performance
mPainter = new Paint(Paint.ANTI_ALIAS_FLAG);
mPainter.setColor(Color.BLUE);
mPainter.setAlpha(128);
}
#Override
public void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawCircle(180, 900, 200, mPainter);
}

The immediate problem is a ClassNotFoundException. When dealing with custom Views in a layout, a common cause for this is an incorrect class name in the layout XML, which seems to have been the issue here. Ensure that the XML tag has the correct, fully-qualified class name for the custom View class, which will be the class's package from the top of the file, prepended to the class name.
Additionally, Views inflated from your layout will be instantiated with a two-argument constructor that takes a Context and an AttributeSet. Your class definition needs to have at least that constructor to allow inflation, or you'll get a NoSuchMethodException. Also, it would make things a little simpler if you'd chain your constructors, if you're just extending View. For example:
public NeckCanvasOverlay(Context context) {
this(context, null);
}
public NeckCanvasOverlay(Context context, AttributeSet attrs) {
super(context, attrs);
initView();
}
It is safer to include all three constructors for the custom View. For example, include the following Constructors for your NeckCanvasOverlay.
public NeckCanvasOverlay(Context context) {
super(context);
initView();
}
public NeckCanvasOverlay(Context context, AttributeSet attrs) {
super(context, attrs);
initView();
}
public NeckCanvasOverlay(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initView();
}
I hope this helps. Give it a try and let me know if you get the same error.
I have a fragment, and I want to click on a button in the fragment to open a corresponding Activity that also hosts a fragment.
I am trying to test how the Activity appears (after button click) and am receiving what appears to be an inflation error. Here is the first fragment containing the button to view the next fragment:
HomePollsFragment.Java
mLatestTestButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent latestActivity = new Intent(getActivity().getApplicationContext(), LatestActivity.class);
startActivity(latestActivity);
}
});
And then here is the code for the activity that is opened on button click:
public class LatestActivity extends AppCompatActivity implements LatestFragment.OnFragmentInteractionListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_latest);
// Check that the activity is using the layout version with
// the fragment_container FrameLayout
if (findViewById(R.id.latest_fragment_container) != null) {
// However, if we're being restored from a previous state,
// then we don't need to do anything and should return or else
// we could end up with overlapping fragments.
if (savedInstanceState != null) {
return;
}
// Create a new Fragment to be placed in the activity layout
LatestFragment latestFragment = new LatestFragment();
// In case this activity was started with special instructions from an
// Intent, pass the Intent's extras to the fragment as arguments
latestFragment.setArguments(getIntent().getExtras());
// Add the fragment to the 'fragment_container' FrameLayout
getSupportFragmentManager().beginTransaction()
.add(R.id.latest_fragment_container, latestFragment).commit();
}
}
#Override
public void onFragmentInteraction(Uri uri) {
}
}
The error I am receiving is below and appears to be related to the following line:

activity_latest.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<fragment

The error is telling you that you have no name attribute on the <fragment> element specifying its class.
NullPointerException: name == null
However, it looks like you mean to load the Fragment yourself, so you don't want a <fragment> element. Instead, you want a ViewGroup that will hold the Fragment after the dynamic FragmentTransaction. Change your <fragment> to a <FrameLayout>.
That because you have a wrong on your activity_latest.xml. You tried to add your LatestFragment to Fragment. You can add fragment into ViewGroup like FrameLayout. Change your code like here.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/latest_fragment_container"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp" />
