Question

我在使用FloatingActionButton时遇到了一些问题，它可以在模拟器上运行，但是当我安装到我的手机（Galaxy s4，Android V4.4.4）时，它无法正常工作我附加了一些图片来说明这个bug。有人能告诉我我能做些什么吗？

我将视图放在片段中

片段类

public class MiniGameMenuFragment extends Fragment implements View.OnClickListener {
    protected FloatingActionButton more_menu_btn, card_view_mode_btn, expand_view_btn;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.mini_menu_fragment, container, false);
        this.more_menu_btn = (FloatingActionButton) view.findViewById(R.id.more_c_btn);
        this.card_view_mode_btn = (FloatingActionButton) view.findViewById(R.id.card_view_mode_c_btn);
        this.expand_view_btn = (FloatingActionButton) view.findViewById(R.id.expand_view_c_btn);

        this.more_menu_btn.setOnClickListener(this);
        this.card_view_mode_btn.setOnClickListener(this);
        this.expand_view_btn.setOnClickListener(this);

        return view;
    }


    @Override
    public void onClick(View v) {

    }

}

在模拟器上

On Phone Galaxy 4s

解决：

问题是提升，因为@SadiqMdAsif说8dp对于我的星系s4分辨率来说太多了，这就是为什么它创造了额外的余量以便我减少到2dp

Answer 1

在设计器页面中使用此选项创建变体

Answer 2

尝试使用相对布局或框架布局而不是线性布局。
