Android: Custom List View is not working properly

My apologies for not providing a proper source code.
basically what I have in my list view xml layout is:
listleave.xml
leaveSummary.xml
leavedB
Custom Adapter
ApplyLeave
I'm creating an app where I have a list view and when I'm running my app I'm getting an error in Locgat.
Caused by:java.lang.NullPointerException: Attempt to invoke virtual
method 'void
android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null
object reference
at com.example.huzai.civilsoft1.ApplyLeave.loadDataInListView(ApplyLeave.java:258 )
at com.example.huzai.civilsoft1.ApplyLeave.onCreate(ApplyLeave.java:84)
In the line loadDataInListView when I'm not commenting l1.setAdapter(customAdapter); the app crashes but when I'm commenting it works properly.
Result of not commenting: l1.setAdapter(customAdapter);
ApplyLeave Activity
public class ApplyLeave extends AppCompatActivity {

Please tell me where I'm going wrong.

You are getting null l1.
Confirm your id of ListView in your activity_apply_leave.xml. It should be leaveApplicationSummary.
EDIT:
Your ListView is in listleave.xml but you are using activity_apply_leave.xml in your Activity.
Move your ListView from listleave.xml to activity_apply_leave.xml.

popup window button not working

I am developing app having a popup window showing successfully but button inside is not working. When the button is click the event is not listening. The code is shown below.

btn_popup_submit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), "aaa", Toast.LENGTH_SHORT).show();
Log.d("LOG","aaaa");
}
});
btn_popup_cancel.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(getApplicationContext(), "bbbb", Toast.LENGTH_SHORT).show();
Log.d("LOG","bbbb");
}
});

I tried different methods but the problem. I don't know where is the problem facing. Please help me thanks.

Replace this line of code.Allow popWindow Touch.
mPopupWindow.setTouchable(false);
to
mPopupWindow.setTouchable(true);

NullPointerException in dialog - Strange case

I have a stupid problem but i couldnt solve it yet. I have an activity with a button in toolbar, this button open one dialog with some filter params.
Here is what a i did..
Spinner spinner_categoria;
Spinner spinner_vendedor;
SeekBar seek_preco;
TextView tv_filtro;
onCreate method {
...
}
onClickEvent{
dialogFiltro();
}
public void dialogFiltro() {
Context context = SalesActivity.this;
final Dialog dialog;
dialog = new Dialog(context);
//dialog.setContentView(R.layout.dialog_filtro);
// dialog.setTitle("Filtro");
//dialog.show();
VendedorDAO auxVendedor = new VendedorDAO();
final List<String> listVendedor = auxVendedor.getVendedorList();
View dialogView = LayoutInflater.from(context).inflate(R.layout.dialog_filtro, null, false);
CardView bt_cancelar = (CardView) dialogView.findViewById(R.id.cb_filtro_cancelar);
CardView bt_aceitar = (CardView) dialogView.findViewById(R.id.cb_filtro_aceitar);
seek_preco = (SeekBar) dialogView.findViewById(R.id.sb_preco_max);
tv_filtro = (TextView) dialogView.findViewById(R.id.tv_filtro_preco);
spinner_categoria = (Spinner) dialogView.findViewById(R.id.spinner_categoria);
spinner_vendedor = (Spinner) dialogView.findViewById(R.id.spinner_vendedor);
spinner_categoria.setAdapter(ArrayAdapter.createFromResource(
this, R.array.categoria_array, android.R.layout.simple_spinner_item));
spinner_vendedor.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, listVendedor));
String oi = "oi";
tv_filtro.setText(oi);
dialog.setContentView(dialogView);
dialog.show();
seek_preco.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
// tv_filtro.setText("R$ " + progress);
// Log.i("RS " , String.valueOf(progress));
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
bt_cancelar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
bt_aceitar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
categoria = (String) spinner_categoria.getSelectedItem();
vendedor = (Integer) spinner_vendedor.getFirstVisiblePosition();
Log.e("id vendedor ", String.valueOf(vendedor));
if (vendedor == 0) {
vendedor = -1;
}
int precoAux = seek_preco.getProgress();
precoMax = (float) precoAux;
}
});
}
I have this in dialog_filtro.xml file:

EDIT: I know what is a NullPointerException, I already checked the previous posts on the subject, but no problem is the same as mine

I think the problem is with findViewByID. The documentation says
findViewById
Added in API level 1
View findViewById (int id)
Finds a child view with the given identifier. Returns null if the specified child view does not exist or the dialog has not yet been fully created (for example, via show() or create()).
It is just possible that since you are calling show() later the textView might not be created. I would do this
View dialogView = LayoutInflater.from(context).inflate(R.layout.dialog_filtro, null);
Button bt_cancelar = (Button) dialogView.findViewById(R.id.cb_filtro_cancelar);
Button bt_aceitar = (Button) dialogView.findViewById(R.id.cb_filtro_aceitar);
seek_preco = (SeekBar) dialogView.findViewById(R.id.sb_preco_max);
tv_filtro = (TextView) dialogView.findViewById(R.id.tv_filtro_preco);
spinner_categoria = (Spinner) dialogView.findViewById(R.id.spinner_categoria);
spinner_vendedor = (Spinner) dialogView.findViewById(R.id.spinner_vendedor);
dialog.setContentView(dialogView)
dialog.show();
spinner_categoria.setAdapter(ArrayAdapter.createFromResource(
this, R.array.categoria_array, android.R.layout.simple_spinner_item));
spinner_vendedor.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,listVendedor));
tv_filtro.setText("oi");

Hope this helps!

SOLVED
The problem was something related android material design, I didn't note before that some layouts has 2 files, so some files were outdated -.-
Thanks for everyone that tried to help.

half or quarter black screen in android

I have an android activity that when I launch sometimes (about 1 in 4 times) it only draws quarter or half the screen before showing it. When I change the orientation or press a button the screen draws properly.
I'm just using TextViews, Buttons, Fonts - no drawing or anything like that.
All of my code for initialising is in the onCreate(). In this method I'm loading a text file, of about 40 lines long, and also getting a shared preference. Could this cause a delay so that it can't draw the intent?
Thanks in advance if anyone has seen anything similar.
EDIT - I tried commenting out the loading of the word list, but it didn't fix the problem.
EDIT 2 - I didn't manage to resolve the problem, but managed to improve it by adding a timer right at the end of the onCreate. I set a low refresh rate and in the tick changed the text of one of the controls. This then seemed to redraw the screen and get rid of the black portions of the screen.
Here is the activity
