Alert Dialog with custom layout failing
- by cmptrer
So this is related to a question I asked earlier. I am trying to display an alert using a specified layout. My layout is:
And the code to call and show the alert dialog is:
Context mContext = getApplicationContext();
AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
// use a custom View defined in xml
View view = LayoutInflater.from(mContext).inflate(R.layout.sell_dialog, (ViewGroup) findViewById(R.id.layout_root));
builder.setView(view);
builder.setPositiveButton(android.R.string.ok, new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// do whatever you want with the input
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
When I run it I get an error saying:
Uncaught handler: thread main exiting due to uncaught exception
android.view.WindowManager$NadTokenException: Unable to add window -- token null is not for an application
I've looked through the android development site and can't figure it out. I think I'm just missing something obvious but the fix isn't jumping out at me. How can I get this alert dialog to display?
