为什么允许从静态对象创建非静态引用？

Question

这是一个例子:

public class Test extends Activity {

    Button button;
    public int i;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        button = (Button) findViewById(R.id.Button01);
        button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                i = 10; // How can this be possible?
            }
        });
    }
}

Answer 1
