Application crashes when opening alertdialog in android - android

I've look in the android documentation on how to implement alertdialog with a xml layout
here is the documentation
when i run the program and click the todo button the program crashes can anyone help?
here's my source code:
import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class StartMoving extends Activity implements OnClickListener {
Button todo;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.start_moving);
todo = (Button) findViewById(R.id.bTodo);
todo.setOnClickListener(this);
}
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bTodo:
AlertDialog.Builder builder;
AlertDialog alertDialog;
Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.to_do_list, null);
builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
alertDialog = builder.create();
alertDialog.show();
break;
default:
break;
}
}
}

this is what the logcat shows

use
Context mContext = v.getApplicationContext();
instead of
Context mContext = getApplicationContext();
or
builder = new AlertDialog.Builder(StartMoving.this);
EDIT :
You are reading button
todo = (Button) findViewById(R.id.bgoto); <-----------
^^^^^
todo.setOnClickListener(this);

AlertDialog.Builder diag = new AlertDialog.Builder(this);
diag.setTitle("DIALOG TITLE")
.setMessage("YOUR MESSAGE")
.setCancelable(false)
.setNegativeButton("WHAT EVER THE BUTTON TEXT",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//enter code here
//do what ever the button in the dialog is clicked
dialog.cancel();
}
});
diag.show();
Easiest way to have a alert dialog
and dont forget to change the Button id in java to R.id.goto

if your are using alertDialog in TabHost then you have to write..
final AlertDialog alertDialog = new AlertDialog.Builder(**getParent()**).create();
//alertDialog.setTitle("Alert....");
alertDialog.setMessage("Your Text");
alertDialog.setButton("OK", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface arg0, int arg1)
{
finish();
}
});
alertDialog.show();

It seems that I've been reading the button from the Context and not from the alertDialog. The solution was to create a View that will be set as View for the AlertDialog and declare a button and set it as a child for the View.
final View view;
LayoutInflater inf = LayoutInflater.from(StartMoving.this);
view = inf.inflate(R.layout.rename, null);
final EditText newname = (EditText) view.findViewById(R.id.etNewRoomName);
final Button todo = (BUtton) view.findViewById(R.id.bTodo);
new AlertDialog.Builder(StartMoving.this)
.setView(view)
.setTitle("Rename")
.setMessage("Enter new name for room " + currentRoom)
.show();

Weird behavior on item click

I'm building an app that sends USSD commands to check for balance, etc.
The apps acts weirdly when I try to launch activities from item click, here from image button: I have to touch two times to launch an activity. I don't know what is wrong.
Have a look at my code:

You are calling openAccountView method by onClick imageView by this:
android:onClick="openAccountView"
So, no need to add onClicklistener to your imageView.
Remove onClicklistener in openAccountView, Use the below code :
public void openAccountView(View view){
Intent i = new Intent(MainActivity.this, AccountActivity.class);
startActivity(i);
}
Hope this helps.

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;
}
});
}

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");

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.

Android custom dialog displays extra space

My custom dialog adds extra space after the Cancel and Save button. I have made a couple of custom dialogs in this app, but this problem appears only in this case. I've colored the view's background to blue, so I think it should be okay.

Displaying the dialog:
Context context = getContext();
final NewRecurrencesDialogView recurrencesDialogView = new NewRecurrencesDialogView(context, subject);
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setView(recurrencesDialogView)
.setTitle(R.string.set_recurrence)
.setPositiveButton(R.string.save, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) { }
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
final Dialog dialog = builder.create();
dialog.setCancelable(false);
dialog.show();
((AlertDialog)dialog).getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<Teaching> newRecurrences = recurrencesDialogView.saveRecurrences();
if (newRecurrences != null) {
recurrences.addAll(newRecurrences);
Collections.sort(recurrences, new Comparator<Teaching>() {
#Override
public int compare(Teaching lhs, Teaching rhs) {
if (lhs.getBegin() < rhs.getBegin())
return -1;
else
return 1;
}
});
updateListViewAdapter();
dataChangedListener.setChanged(true);
dialog.dismiss();
}
}
});
((AlertDialog)dialog).getButton(AlertDialog.BUTTON_NEUTRAL).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
I've compared the layout file with the other dialog's files, but can't figure out where the problem is.

I think the problem is with the android:layout_weight you set for your view.
Try change your:
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0.2"
android:visibility="visible"/>
To this:
<View
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.2"
android:visibility="visible"/>
I am not really sure what you trying to achieve, but think this will show you the direction (hopefully the right one).
