How to display the dialog from ime service in android programatically?

Question

Can anyone help me to display the custom dialog from the ime service. I have searched lot of things on the internet but nothing got usefull to popup the dialog from the ime service.

I'm using below code to display dialog :

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
LayoutInflater layoutInflaterAndroid = LayoutInflater.from(context);
View view = layoutInflaterAndroid.inflate(R.layout.my_dialog, null);
builder.setView(view);
builder.setCancelable(false);
AlertDialog alertDialog = builder.create();
alertDialog.show();

But I'm getting below error :

Answer 1

I found the solution. It's very simple just use below code :

View dialogView = LayoutInflater.from(context).inflate(R.layout.my_dialog, new FrameLayout(context));

PopupWindow popup = new PopupWindow(context);
popup.setContentView(dialogView);
// If you need the PopupWindow to dismiss when when touched outside
popup.setBackgroundDrawable(new ColorDrawable());

popup.showAtLocation(mInputView, Gravity.CENTER, 0, 0);

Button btnCancel = dialogView.findViewById(R.id.cancel_button);
btnCancel.setOnClickListener(v -> popup.dismiss());

Thank you. Enjoy the code. :)
