How to go to another activity from button looping?

Question

How to go to another activity? I'm trying to go another activity from button. If I click one of the buttons, button must redirect to another actitivity, chapters.class. I tried Toast.make in OnClick function. It works. But when I coded to go another activity, apps crashed. How to solve that? Here is the code:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.oldtestament);
    LinearLayout layout = (LinearLayout) findViewById(R.id.linearlayoutold);
    String[] values = { "Apple","Orange","Twitter","Yahoo","Google","English","Reddit","Settings" };
    Button[] b = new Button[values.length];
    for (int i = 0; i < b.length; i++) {
        b[i] = new Button(this);
    }
    for (int i = 0; i < values.length; i++) {
        LayoutParams params = new LinearLayout.LayoutParams(
                LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);             
        ((MarginLayoutParams) params).setMargins(18, 2, 18, 2);
        b[i].setText(values[i]); 
        layout.addView(b[i], params);
        addListenerOnButton(b[i]);
    }
}

public void addListenerOnButton(Button b) {
    final Context context = this;
    b.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            Intent intent = new Intent(context, chapters.class);
            startActivity(intent);
        }

    });

}

Here is LogCat:

Answer 1

Hu....

In Androidminifest.xml:

I add:

<activity
        android:name=".chapters"
        android:label="@string/app_name" >

Stupid me. I thought Elcipse will do it automactically.

Answer 2

try this one, Just edit your context like this

Intent intent = new Intent(getApplicationContext(), chapters.class);
startActivity(intent);

I think you having problem due to final Context context = this;
