Question

我正在尝试将TransitionListener添加到默认活动转换中，如下所示：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (savedInstanceState == null && Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        getWindow().getEnterTransition().addListener(new TransitionAdapter());
    }
}

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private class TransitionAdapter implements Transition.TransitionListener {
    @Override
    public void onTransitionStart(Transition transition) {
        Log.i("transition", "onTransitionStart");
    }

    @Override
    public void onTransitionEnd(Transition transition) {
        Log.i("transition", "onTransitionEnd");
    }

    @Override
    public void onTransitionCancel(Transition transition) {
        Log.i("transition", "onTransitionCancel");
    }

    @Override
    public void onTransitionPause(Transition transition) {
        Log.i("transition", "onTransitionPause");
    }

    @Override
    public void onTransitionResume(Transition transition) {
        Log.i("transition", "onTransitionResume");
    }
}

这是我如何开始活动： Intent intent = new Intent（activity，LoginActivity.class）;

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        Bundle options = ActivityOptions.makeSceneTransitionAnimation(activity).toBundle();
        activity.startActivityForResult(intent, RequestCodes.SIGN_IN, options);
    } else {
        activity.startActivityForResult(intent, RequestCodes.SIGN_IN);
    }

问题是真实设备上没有调用回调。它适用于genymotion。是否需要一些额外的设置？

免责声明：我在lolipop运行设备上测试它

发现它在5.0上不起作用但在5.1上修复了所以它显然是一个安卓漏洞。虽然我不知道解决方法。我已将转换限制为最低API 22。

听取默认活动转换
