Android自定义View类访问静态对象

public interface MyCallback {
    void onCallback();
}

public class MyView extends View implements MyCallback {
    private static MyObject myObject;

    public MyView(Context context, MyObject object) {
        super(context);
        myObject = object;
    }

    @Override
    public void onCallback() {
        // 访问静态对象的方法
        myObject.doSomething();
    }
}

public class MainActivity extends AppCompatActivity {
    private MyObject myObject;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        myObject = new MyObject();

        MyView myView = new MyView(this, myObject);
        // 设置回调
        myObject.setCallback(myView);
    }
}
