Basic Android development questions

Question

onCreate(Bundle State)
{
    TextView label = new TextView(this);
    lable.setText("My new Label");
}

I read that the TextView has a reference to the Activity . What does it mean for something to have a reference on something else?

Answer 1

每当活动是活动包含文本视图时，文本视图将自动被销毁。

Answer 2

从实际的角度来看，这意味着不建议您将TextView保留在静态变量中的某个位置，因为那样您将保留整个Activity。
