家長活動我想在基本活動中播放視頻，因此每個子活動都必須在每個活動中播放無縫視頻public abstract class BaseActivity extends AppCompatActivity {@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); super.setContentView(R.layout.splash); }}兒童活動 public class LoginActivity extends BaseActivity {@Overrideprotected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); super.setContentView(R.layout.splash);}}
是否可以將 Activity 背景置于其子 Activity 之上
