Can you fire an event when Android Dialog is dismissed?

问题

Say I have a created a dialog in my Android app like so:

private static ProgressDialog dialog;
dialog = ProgressDialog.show(MainActivity.this, "", "Downloading Files. Please wait...", true);

Now, is it possible to fire an event when the following is called?

dialog.dismiss();

The reason I want to do this and not just call my method after dialog.dismiss(); is because the Dialog dismiss is called within a static class and the next thing I want to do is load a new Activity (which cannot be done using Intents within a static class).

回答1:

Use an OnDismissListener.

There is a setOnDismissListener(...) method in the class Dialog

回答2:

Sure you can - check:

  public void onDismiss(DialogInterface dialogInterface)
  {
        //Fire event
  }

回答3:

Whenever a dialog is closed either by clicking PositiveButton, NegativeButton, NeturalButton or by clicking outside of the dialog, "onDismiss" is always gets called automatically so do your stuff inside the onDismiss() method e.g.,

@Override
public void onDismiss(DialogInterface dialogInterface) {
    ...
}

You don't even need to call dismiss() method.

回答4:

If you are within custom dialog class - override dismiss(). I recommend inserting logic BEFORE super.dismiss(). Kotlin example:

override fun dismiss() {
    Utils.hideKeyboard(mContext, window)
    super.dismiss()
}

回答5:

Use setOnDismissListener method for the dialog.

dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
    @Override
    public void onDismiss(DialogInterface dialog) {
        if (mIsSettingsDirty)
            refreshRecyclerView();
    }
});
