What is the problem? Where am I going wrong? How should I populate the spinner?

You should
return view;
instead of
return container;
in your onCreateView(.....) in PlacementFragment
also change this
ArrayAdapter<MyData> adapter = new ArrayAdapter<MyData>(activity,
android.R.layout.simple_spinner_item, items);
to
ArrayAdapter<MyData> adapter = new ArrayAdapter<MyData>(getActivity(),
android.R.layout.simple_spinner_item, items);

Caused by: java.lang.NullPointerException
android.widget.ArrayAdapter.init(ArrayAdapter.java:310)
Apart form the other answer you need to change to
ArrayAdapter<MyData> adapter = new ArrayAdapter<MyData>(getActivity(),
android.R.layout.simple_spinner_item, items);
Activity activity; activity is not initialized.

Try this..
You have not initialize Activity activity initialize it as
activity = getActivity();

I put a button inside the fragment marker in my navigation drawer. The application crashes when the button is clicked

The application crashes when I add the setText into the onclickListener.
buttonlar = container.findViewById(R.id.buttonlar);
text = container.findViewById(R.id.text);
View view = inflater.inflate(R.layout.fragment_first, container, false);
buttonlar = view.findViewById(R.id.buttonlar);
buttonlar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
text.setText("test");
}
});
return view;
}

I believe you should be getting the TextView from the inflated view instead of the container (whatever that may be). Try the following,
//buttonlar = container.findViewById(R.id.buttonlar);
//text = container.findViewById(R.id.text);
View view = inflater.inflate(R.layout.fragment_first, container, false);
buttonlar = view.findViewById(R.id.buttonlar);
//Use the inflated view to get the text (just like you did for buttonlar)
text = view.findViewById(R.id.text);
buttonlar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
text.setText("test");
}
});
return view;
}

Can't run App on Note 2 because of too many images (only 20 images)

I am getting the following error when I go from my Main Activity page to my New Activity page. The New Activity page crashes unless it has <10 images or so, which is pathetic (the app runs fine emulated on my computer, however):

I understand that the out of memory error occurs when the ram for a phone runs out when processing too many bitmaps.
Yes, I have read the Android Developer webpages on tips for processing bitmaps. However, I still don't understand which groups of code from their guides I'm supposed to insert, and where I'm supposed to insert it. I've tried inserting some of their stuff into my .java files but I just end up getting errors. I owe this to me being a beginner at Java and not understanding how to apply the example codes.
Again, I am a beginner to Java and Android Studio so please go easy on me and explain things as simply as you can, if possible.
Here's my code:

//Main Activity Mario Icon:

ImageButton Luigi;
#Override

setContentView(R.layout.activity_main);
Mario= (ImageButton) findViewById(R.id.Mario);
Mario.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intentLoadNewActivity = new Intent(MainActivity.this, NewActivity.class);
startActivity(intentLoadNewActivity);
}
});
Luigi= (ImageButton) findViewById(R.id.Luigi);
Luigi.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intentLoadNewActivity = new Intent(MainActivity.this, Main2Activity.class);
startActivity(intentLoadNewActivity);
}
});
}
}

If your images are too high-resolution, they can eat up a LOT of memory, especially if you have 20 of them as you say. Consider using Picasso or some other library to load your images.

How to create a custom adapter for a listview? Getting RessourceNotFoundException

I am trying to make a custom adapter for my listview, but I keep getting a RessourceNotFoundException on the same line.
Firstly, here is my adapter class code:
public class CreateProgramAdapter extends BaseAdapter {
private final LayoutInflater inflater;
private ArrayList<TrainingPass> trainingPasses;
private List<TrainingPass> items;
private int layoutResourceId;
private Context context;
public CreateProgramAdapter(Context context, List<TrainingPass> items) {
this.context = context;
this.items = items;
inflater = LayoutInflater.from(this.context);
}
#Override
public int getCount() {
return items.size();
}
#Override
public Object getItem(int position) {
return items.get(position);
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
TrainingPassHolder holder;
if(convertView == null) {
convertView = inflater.inflate(R.layout.adapter_createprogram_trainingpasses_item, null);
holder = new TrainingPassHolder();
convertView.setTag(holder);
} else {
holder = (TrainingPassHolder) convertView.getTag();
}
holder.trainingPass = this.items.get(position);
holder.trainingPassRelativeLayout = (RelativeLayout) row.findViewById(R.id.trainingpass_item_relativelayout);
holder.headlineTxt = (TextView) row.findViewById(R.id.trainingpass_headline);
holder.setNoTxt = (TextView) row.findViewById(R.id.txt_trainingpass_setno);
holder.showHideIcon = (ImageView) row.findViewById(R.id.trainingpass_showhide_imageview);
holder.exerciseSearchField = (EditText) row.findViewById(R.id.trainingpass_exercise_searchfield);
holder.repsTextField = (EditText) row.findViewById(R.id.trainingpass_reps_txtfield);
holder.addSetButton = (Button) row.findViewById(R.id.add_set_button);
holder.addExerciseButton = (Button) row.findViewById(R.id.trainingpass_addexercise_button);
holder.setsListView = (ListView) row.findViewById(R.id.trainingpass_sets_listview);
holder.exercisesListView = (ListView) row.findViewById(R.id.trainingpass_exercises_listview);
holder.trainingPassRelativeLayout.setTag(holder.trainingPass);
holder.headlineTxt.setTag(holder.trainingPass);
holder.setNoTxt.setTag(holder.trainingPass);
holder.showHideIcon.setTag(holder.trainingPass);
holder.exerciseSearchField.setTag(holder.trainingPass);

holder.addExerciseButton.setTag(holder.trainingPass);

return convertView;
}

}
public static class TrainingPassHolder {

}
And here is the xml for the view, containing the listview:

And this is the code for setting the adapter in my activity (extends Activity)
ArrayList<TrainingPass> trainingPasses = new ArrayList<TrainingPass>();
TrainingPass trainingPass = new TrainingPass();
trainingPass.setTrainingPassName("wefwef");
TrainingPass trainingPass2 = new TrainingPass();
trainingPass.setTrainingPassName("rwefhtr");
trainingPasses.add(trainingPass);
trainingPasses.add(trainingPass2);
ListView trainingPassesListView = (ListView)findViewById(R.id.listView_trainingpasses);
CreateProgramAdapter createProgramAdapter = new CreateProgramAdapter(CreateProgramActivity.this, trainingPasses);
trainingPassesListView.setAdapter(createProgramAdapter);
The error i am getting is this:

The error refers to line 56 in my adapterclass, which is the following line:
convertView = inflater.inflate(R.layout.adapter_createprogram_trainingpasses_item, null);
I really can't seem to find out what may be wrong with the code, so I hope someone can help me out.
Thanks

Thanks to JafarKhQ, I solved the problem.
By changing the layout "adapter_createprogram_trainingpasses_item .xml" to the following, it worked:

Dialog Fragment is crashing

i have a Dialog fragment that i show using. Btw i have updated my support libraries to include material design theme and new classes. Is it possible that the new fragmentDialog fragments are buggy
fragment.show(getSupportedFragmentManager(),null);
here is the code for the fragment
public class NewTimedEvent extends DialogFragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_new_timed_event, container, false);
}
#Override // show User interface in a dialog
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the Builder class for convenient dialog construction
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.fragment_new_timed_event, null);
builder.setView(view);
builder.setPositiveButton(getString(android.R.string.ok), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
builder.setNegativeButton(getString(android.R.string.cancel), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
// Create the AlertDialog object and return it
return builder.create();
}
}
here is the error is get
