Second Activity Won't Start Adapter class

I am trying to create a recycle view list of NBA teams and when each team is clicked it will display a recycler view list of the NBA players in that particular team. To do this, I have constructed my main activity, which will launch the "NBA_Adapter" in the OnCreate method as shown below:
package com.example.nba;
public class MainActivity extends AppCompatActivity implements SearchView.OnQueryTextListener {
state state = new state();
private NBA_Adapter adapter;
private RecyclerView recyclerView;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(this);
return true;
}
#Override
public void onCreate(Bundle savedInstanceState) {//originally 'protected'
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = findViewById(R.id.recycler_view);
adapter = new NBA_Adapter(getApplicationContext());
recyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL, false));
}
}
NBA_Adapter:
package com.example.nba;
public class NBA_Adapter extends RecyclerView.Adapter<NBA_Adapter.NBAViewHolder> implements Filterable {
public static class NBAViewHolder extends RecyclerView.ViewHolder { //constructer for recyclerview adapter
public LinearLayout containerView;
public TextView textView;
NBAViewHolder(View view) {
super(view);
containerView = view.findViewById(R.id.nba_row);
textView = view.findViewById(R.id.nba_row_text_view);
containerView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
TEAMS current = (TEAMS) containerView.getTag();
Intent intent = new Intent(v.getContext(), SecondMain.class);
intent.putExtra("id", current.getId());
v.getContext().startActivity(intent);
}
});
}
}
}
Second Main:
public class SecondMain extends AppCompatActivity implements SearchView.OnQueryTextListener {
private int team_id;
private Player_Adapter rapter;
private RecyclerView mrecyclerView;
private RecyclerView.LayoutManager layoutManager;
#Override
public void onCreate(Bundle savedInstanceState) {//originally 'protected'
Log.v("cs100", "I exist!");
team_id = getIntent().getIntExtra("id",0);
Log.v("cs100", "" + team_id);
super.onCreate(savedInstanceState);
setContentView(R.layout.second_main);
mrecyclerView = findViewById(R.id.mrecycler_view);
rapter = new Player_Adapter(getApplicationContext());
mrecyclerView.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));
state.setstate(false);
mrecyclerView.setAdapter(rapter);
}
}
Android Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.nba">
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".SecondMain">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Now I am able to launch the "SecondMain" class as evident of a Log.v statement printing(Meaning at this point the teams but not the players in the teams are displaying). Since "MainActivity" is almost identical to "SecondMain" I assumed that similar to how "MainActivity" launches "NBA_Adapter" so will "SecondMain" launch "Player_Adapter". Player_Adapter is almost identical to "NBA_Adapter" but it is not launching at all. This is why I suspect that the problem is how I described "SecondMain" in the Android Manifest. I only included the relevant parts for each class. Any tips or links on this issue is appreciated, thanks!
EDIT: Included Player_Adapter class below:
public class Player_Adapter extends RecyclerView.Adapter<Player_Adapter.PlayerViewHolder> implements Filterable {
private int team_id;
public class myclass extends AppCompatActivity{
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
team_id = getIntent().getIntExtra("id",0);
recyclerView.setAdapter(adapter);
Log.v("Player",""+ team_id); //Not displaying statement which indicates that "Player_Adapter" is not being launched
}
}
public static class PlayerViewHolder extends RecyclerView.ViewHolder {
public LinearLayout containerView;
public TextView textView;
PlayerViewHolder(View view) {
super(view);
containerView = view.findViewById(R.id.Player_List_row);
textView = view.findViewById(R.id.Player_List_row_text_view);
containerView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Players current = (Players) containerView.getTag();
Intent intent = new Intent(v.getContext(), Compare_Stats.class);
//we get the "fullName"
intent.putExtra("id", current.getPlayer_id());
v.getContext().startActivity(intent);
}
});
}
}
#NonNull
#Override
public PlayerViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
final View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.player_list, parent, false);
return new PlayerViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull PlayerViewHolder holder, int position) {
Players current = PlayersList.get(position);
holder.textView.setText(current.FullName());
holder.containerView.setTag(current);
}
#Override
public int getItemCount() {
return PlayersList.size();
}
}

Inside the class myclass you are definitely setting the adapter , but it looks like you are missing the code that sets the LayoutManager to RecyclerView .
recyclerView.setLayoutManager(new LinearLayoutManager(this/*Context here*/));
Another suggestion is that you should keep activity separately and not nest it inside a adapter.

'class' or 'interface' expected in AndroidManifest.xml

I keep getting this build error 'class' or 'interface' expected. Everything I'm finding on SO is saying that my Java class is missing (or has an extra) a "}" I'm getting this error in my AndroidManifest.xml for all my Java activities. Here is the Java code:
public class MainActivity extends AppCompatActivity {

I keep getting build errors and am not able to do any commits. It was working fine the other day so I'm not really sure what changed. I can post my other activities if needed.

}

Try a period before MainActivity where it's declared in the manifest.

Android: startActivity() works for one activity but not another

Part of an app I'm working on has two buttons, and my problem is that when I call startActivity() it will work as expected for one activity but not another.
So this works:
startActivity(new Intent(StartScreenActivity.this, FiltersActivity.class));
But this does not:
startActivity(new Intent(StartScreenActivity.this, MainActivity.class));
Both worked fine yesterday, but since updating Android Studio this morning nothing happens when I try to start MainActivity. Both are present in my manifest:
<activity
android:name=".FiltersActivity"
android:label="#string/title_activity_filters"
android:theme="#style/AppTheme.NoActionBar" >
</activity>
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:theme="#style/AppTheme.NoActionBar" >
</activity>
There are no errors thrown to the LogCat or anything like that, simply one works and nothing happens for the other. I would assume something is wrong with the MainActivity class, but it worked fine until a few hours ago and the only changes since then have been updating Studio, as I mentioned, and some small xml layout changes to the main activity layout file which I have tried undoing but that doesn't fix the problem.

Change your <activity> in manifest with:
<activity
android:name=".FiltersActivity"
android:label="#string/title_activity_filters"
android:theme="#style/AppTheme.NoActionBar" >
<intent-filter>
<action android:name="me.theglassboard.vee.FiltersActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main"
android:theme="#style/AppTheme.NoActionBar" >
<intent-filter>
<action android:name="me.theglassboard.vee.MainActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

Try the follow:
reference your button like this:
mButton1 = (Button) findViewById(R.id.button_1);
mButton2 = (Button) findViewById(R.id.button_2);
call your button with onClickListener
mButton1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent button1 = new Intent(StartScreenActivity.this, FiltersActivity.class);
startActivity(button1);
}
}
mButton2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent button2= new Intent(StartScreenActivity.this, MainActivity.class);
startActivity(button);
}
}
if not working, send printout of the MainsActivity.class and StartScreenActivity

app crashing when switching activities

Hi so I have been going at this for days and I keep getting a crash everytime I try to move into my list view activity. I have rewritten the list view activity twice here is the activity code:

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_exersise_display);

if(e==null){
//success
exercise_name = list;
Excercise_Adapter adapter = new Excercise_Adapter(getListView().getContext(), exercise_name);
setListAdapter(adapter);
}
else {
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_exersise__display, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
here is the Exercise Adapter class
protected Context mContext;
protected List mExercise;
public Excercise_Adapter (Context context, List exercise){
super(context, R.layout.da_excerisises, exercise);
mContext = context;
mExercise = exercise;
}
#Override

You should return convertView in your adapter getView instead of calling super. Plus if this didnt help you please post the code to start your activity.
edit
Please add the two of your activities into the manifest inside of application tag ex:
<activity android:name="myActivity">
<activity android:name="myActivity"Two>

Open Properties->Java Build Path->Order and Export and check QB jar library. According to logs you haven't added it to the build.

1) First of all make sure that you have imported "quickblox-android-1.2.2.jar" which comes with QuickBlox SDK in folder named jar then just Right click on project -> Properties -> Got to Java Build Path -> Order and Export -> just check quickblox-android-1.2.2.jar(which is unchecked in list) -> click Ok.
2)Just Clean the project and run it.
Note:- If you do not clean the project after step 1 then project will crash so clean the project before running it.
