Question

I get an error like this in logcat when i try to run my script. I compared it and it is the onClickListener. Any suggestions to fix this problem? Still a beginner.

Answer 1

The problem exists here:

View splashscreen = (View) findViewById(R.layout.splash);
splashscreen.setOnClickListener(this);

You are getting an exception because splashscreen is null, and calling setOnClickListener() on a null pointer is not allowed. The reason that pointer is null is because you need to obtain a reference to the view from your XML using a proper ID. Your splash.xml file located in res/layout is being loaded as the content view for the Activity, but you should have a proper R.id value associated with that particular view.

In splash.xml, the View you declare for this purpose should have an android:id="@+id/something" attribute in it’s XML declaration (I picked “something” out of the air, this identifier can be whatever you want). You would then call:

//Hint: You don't have to cast the result if the pointer is a plain vanilla View
View splashscreen = findViewById(R.id.something);
splashscreen.setOnClickListener(this);

Then you will get a valid reference to the view and your set method will not fail.
