[java] Prevent Android activity dialog from closing on outside touch

I have an activity that is using the Theme.Dialog style such that it is a floating window over another activity. However, when I click outside the dialog window (on the background activity), the dialog closes. How can I stop this behaviour?

Alert Dialog is deprecated so use Dialog dialog = new Dialog(this);

For prevent close on outside touch

dialog.setCanceledOnTouchOutside(false);

What you actually have is an Activity (even if it looks like a Dialog), therefore you should call setFinishOnTouchOutside(false) from your activity if you want to keep it open when the background activity is clicked.

EDIT: This only works with android API level 11 or greater

Setting the dialog cancelable to be false is enough, and either you touch outside of the alert dialog or click the back button will make the alert dialog disappear. So use this one:

setCancelable(false)

And the other function is not necessary anymore: dialog.setCanceledOnTouchOutside(false);

If you are creating a temporary dialog and wondering there to put this line of code, here is an example:

new AlertDialog.Builder(this)
                        .setTitle("Trial Version")
                        .setCancelable(false)
                        .setMessage("You are using trial version!")
                        .setIcon(R.drawable.time_left)
                        .setPositiveButton(android.R.string.yes, null).show();

To prevent dialog box from getting dismissed on back key pressed use this

dialog.setCancelable(false);

And to prevent dialog box from getting dismissed on outside touch use this

 dialog.setCanceledOnTouchOutside(false);

Simply,

alertDialog.setCancelable(false);

prevent user from click outside of Dialog Box.

Use This Code it's Working For me

 AlertDialog.Builder alertDialog = new AlertDialog.Builder(this);
 alertDialog.setCancelable(false);

This is the perfect answer to all your questions.... Hope you enjoy coding in Android

new AlertDialog.Builder(this)
            .setTitle("Akshat Rastogi Is Great")
            .setCancelable(false)
            .setMessage("I am the best Android Programmer")
            .setPositiveButton("I agree", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();

                }
            })
            .create().show();

What worked for me was to create DialogFragment an set it to not be cancelable:

dialog.setCancelable(false);

        alert.setCancelable(false);
        alert.setCanceledOnTouchOutside(false);

I guess this will help you.It Worked For me

Also is possible to assign different action implementing onCancelListener:

alertDialog.setOnCancelListener(new DialogInterface.OnCancelListener(){                   
    @Override
    public void onCancel(DialogInterface dialogInterface) {
        //Your custom logic
    } 
});

Use setFinishOnTouchOutside(false) for API > 11 and don't worry because its android's default behavior that activity themed dialog won't get finished on outside touch for API < 11 :) !!Cheerss!!

I was facing the same problem. To handle it I set a OntouchListener to the dialog and do nothing inside. But Dialog dismiss when rotating screen too. To fix it I set a variable to tell me if the dialog has normally dismissed. Then I set a OnDismissListener to my dialog and inside I check the variable. If the dialog has dismmiss normally I do nothin, or else I run the dialog again (and setting his state as when dismissing in my case).

Dialog dialog = new Dialog(context)
dialog.setCanceledOnTouchOutside(true); 
//use this to dismiss the dialog on outside click of dialog

dialog.setCanceledOnTouchOutside(false);
//use this for not to dismiss the dialog on outside click of dialog.

Watch this link for more details about dialog.

dialog.setCancelable(false);
//used to prevent the dismiss of dialog on backpress of that activity

dialog.setCancelable(true);
//used to dismiss the dialog on onbackpressed of that activity

Here is my solution:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select The Difficulty Level");
builder.setCancelable(false);

I use this in onCreate(), seems to work on any version of Android; tested on 5.0 and 4.4.x, can't test on Gingerbread, Samsung devices (Note 1 running GB) have it this way by default:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
    {
        setFinishOnTouchOutside(false);
    }
    else
    {
        getWindow().clearFlags(LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);
    }

    super.onCreate(savedInstanceState);

When using dialog as an activity in the onCreate add this

setFinishOnTouchOutside(false);

For higher API 10, the Dialog disappears when on touched outside, whereas in lower than API 11, the Dialog doesn't disappear. For prevent this, you need to do:

In styles.xml: <item name="android:windowCloseOnTouchOutside">false</item>

OR

In onCreate() method, use: this.setFinishOnTouchOutside(false);

Note: for API 10 and lower, this method doesn't have effect, and is not needed.

builder.setCancelable(false);

public void Mensaje(View v){

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("¿Quieres ir a el Menú principal?");
    builder.setMessage("Al presionar SI iras a el menú y saldras de la materia.");
    builder.setPositiveButton("SI", null);
    builder.setNegativeButton("NO", null);
    builder.setCancelable(false);
    builder.show();
}
