隐藏操作栏会导致RelativeLayout中底部对齐的项目跳转 [英] Hiding the action bar causes bottom aligned item in RelativeLayout to jump

问题描述

我有 RelativeLayout ，其视图与父底部对齐.当我调用 actionBar.hide()时，视图随着操作栏向上滑动而向上滑动，然后一旦操作栏完全消失，视图就会跳回到底部.

i have RelativeLayout with a view that is aligned to the parent bottom. when i call actionBar.hide() the view slides up as the action bar slides up, then once the action bar has fully disappeared, the view jumps back to the bottom.

我如何防止这种情况发生?我希望视图在操作栏向上滑动时保持在底部.

how do i prevent this from happening? i want the view to stay attached to the bottom as the action bar slides up.

选项卡是底部对齐的.(您在上面看到的灰色内容是一个正在加载的不同片段，因此请忽略它)

the tabs are what are bottom aligned. (the grey stuff you see above is a different fragment being loaded so ignore that)

代码:

public class MainFragment extends Fragment {
    public View onCreateView(...) {
        return inflater.inflate(R.layout.fragment_main);
    }
    public void onResume() {
        super.onResume();
        getActivity().getActionBar().hide();
    }
    public void onPause() {
        super.onPause();
        getActivity().getActionBar().show();
    }
}

R.layout.fragment_main:

R.layout.fragment_main:

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:text="test" />
</RelativeLayout>

推荐答案

以您的AppTheme样式设置操作栏叠加模式:

Set action bar overlay mode in your AppTheme style:

<item name="android:windowActionBarOverlay">true</item>
<!-- Support library compatibility -->  
<item name="windowActionBarOverlay">true</item>

，并根据需要在布局文件中设置填充或边距，如下所示:?android:attr/actionBarSize

and, if you need, set padding or margin in your layout file like this: ?android:attr/actionBarSize
