How to check if dialog is displayed or display multiple dialogs of the same type?

Question

I'm managing dialogs by showDialog/dismissDialog/removeDialog.

I want to:

Display several dialogs in kind of a stack:

a) First dialog is shown using showDialog(DIALOG_TYPE)

b) Next dialogs are shown on top of the existing dialog

Now I'm only able to display first dialog using showDialog and then next dialogs are ignored.

Display last dialog:

a) First dialog is shown using showDialog(DIALOG_TYPE)

b) Application checks if dialog is displayed, closes dialog (if it's displayed) and opens a new dialog.

Is there any possibility to achieve one of the above solutions?

Dialog has an isShowing() method that should return if the dialog is currently visible. So you can use that to see if a dialog is showing and hide it with dismissDialog(). You just have to keep a reference to the Dialogs you create in onCreateDialog().

Ok, this satisfies the first scenario, but what about stacking? Maybe there is some possibility to show several dialogs of the same type? – pixel Jun 30 '10 at 20:28

Doesn't seem to work for stacking. If I stack multiple dialogs on top of each other, both have true for the showing property. – Lance Nanek Oct 15 '13 at 18:09
I don't know why calling *getDialog().isShowing()* from DialogFragment make it can't be showed, it's so crazy. – Phong Nguyen Apr 19 '19 at 03:42
@PhongNguyen DialogFragment has `isVisible()` – 6rchid Jun 18 '23 at 03:50

Dialog implements DialogInterface which has OnShowListener.

Therefore you can use code like this:

Dialog dialog = new Dialog(context);
// ... set all things considering your dialog
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {
        // do something when your dialog is shown    
    }
});

You can use flag to check whether dialog is opened or not and according to flag value you can do whatever you want. Like I did. I am having only one dialog but when I touch another EditText and if my dialog is opened then it should close first and then should re-open with animation.

Code snippet:

    private EditText mEditText, mEditCode;
    private Dialog mDialog;
    private int mClicked = 0;
    private boolean isShown = false;

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        mEditText = (EditText)findViewById(R.id.EnterValue);
        mEditText.setClickable(true);
        mEditText.setOnClickListener(this);

        mEditCode = (EditText)findViewById(R.id.EnterCode);
        mEditCode.setClickable(true);
        mEditCode.setOnClickListener(this);
    }

    public void onClick(View nView)
    {
        switch (nView.getId()) 
        {
        case R.id.EnterValue:
            mClicked = R.id.EnterValue;
            mEditText.requestFocus();
            mEditText.setFocusableInTouchMode(false);
            mEditText.setEnabled(true);
            mEditText.setSelection(mEditText.getText().toString().trim().length());
            if(isShown)
            {
                mDialog.dismiss();
                showInfoDialog();
            }
            else
            {
                showInfoDialog();
            }
            break;
        case R.id.EnterCode:
            mClicked = R.id.EnterCode;
            mEditCode.requestFocus();
            mEditCode.setFocusableInTouchMode(false);
            mEditCode.setEnabled(true);
            mEditCode.setSelection(mEditCode.getText().toString().trim().length());
            if(isShown)
            {
                mDialog.dismiss();
                showInfoDialog();
            }
            else
            {
                showInfoDialog();
            }
            break;
        }
    }

    private boolean showInfoDialog() 
    {
        mDialog = new Dialog(CustomKeyboardNotLikeAndroidActivity.this, R.style.PauseDialog);
        mDialog.setContentView(R.layout.keyboard);
        mDialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;
        mDialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL, WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL);
        mDialog.setCancelable(true);
        isShown = true;
        mDialog.show();
        return false;
    }

Try to alter this code in your way. Hope this can help you. Thanks.
