如何使FAB在活动的片段而不是AppCompatActivity中工作 [英] How to make FAB work in Fragment from a Activity and not in AppCompatActivity

问题描述

我将FAB放在活动的片段中，并且不断出现此错误:

I'm putting my FAB in a Fragment from an Activity and I keep getting this error:

等级设置为

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'

膨胀的完成方式:

View mView = inflater.inflate(getlayoutResId(), container, false);

我唯一没有更改的是将Activity更改为AppCompatActivity，它将击中许多现有代码. 我们有办法使该FAB与Activity一起使用吗?

The only thing that I haven't changed is the Activity to AppCompatActivity which will hit a lot of existing codes. Do we have a way to make this FAB work with Activity?

FAB:

<android.support.design.widget.FloatingActionButton
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="16dp"
    android:src="@drawable/pichere"
    app:backgroundTint="@color/white"
    app:borderWidth="0dp" />

谢谢！

如果我做错了设计，请告诉我我可以做些什么，以使FAB可以制作此片段.

If I am making a wrong design, please advise on what else I can do to make this fragment with FAB work.

推荐答案

Do we have a way to make this FAB work with Activity?

不直接. android.support.design.widget.FloatingActionButton需要AppCompatActivity和Theme.AppCompat.

我在此库中有一个与该小部件交叉的端口， Activity(或FragmentActivity)，但minSdkVersion为21或更高，因为它需要Theme.Material.

I have a cross-port of that widget in this library that works with a regular Activity (or FragmentActivity), but it is for a minSdkVersion of 21 or higher, as it requires Theme.Material.

还有其他FAB实施，例如此，不需要appcompat-v7和不需要Theme.Material.

There are other FAB implementations, such as this one, that do not require appcompat-v7 and do not require Theme.Material.
