Create your dialog in Android (dirty trick in official documentation)

I decided to create my own Dialog in andriod. Knowledge gained from official documentation. But as it turned out there is a catch. If you follow the recommendations from the Creating a Custom Dialog documentation, you always get an error:



Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application



an error causes the method:



@Override

protected Dialog onCreateDialog(int id) {

Context mContext = getApplicationContext();

Dialog dialog = new Dialog(mContext);



dialog.setContentView(R.layout.quicklog);

dialog.setTitle("Custom Dialog");

TextView text = (TextView) dialog.findViewById(R.id.text);

text.setText("Hello, this is a custom dialog!");



return dialog;

}



The reason is that the wrong context is passed to the Dialog object's constructor:

')

Context mContext = getApplicationContext();

Dialog dialog = new Dialog(mContext);





Fixed easy enough. Change getApplicationContext() to this :



Dialog dialog = new Dialog(this);





I think this inaccuracy will be corrected in the documentation later, but be careful.
