I think you forgot to “return true;” in function onTouch.

You need to import the FrameLayout widget.

Add import android.widget.FrameLayout to the top of your code.

I think there are a few other imports I forgot to list. The editor I was using adds them automagically.

I’m such a java noob, but I’m trying to learn the basics to program some stuff for android. This tutorial is great: it explains things really well. However, I am having trouble when trying to compile the source code. Can anyone help? Here is my source for the main class:

package com.mpruitt105.drawcircle;

import android.app.Activity;
import android.os.Bundle;

public class DrawCircle extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
FrameLayout main = (FrameLayout) findViewById(R.id.main_view);
main.addView(new Ball(this,50,50,25));
}
}

It has 2 errors that both say ‘FrameLayout cannot be resolved to a type’

Does anyone know what the heck that means? I’m so lost. Thanks
