显示不带CoordinatorLayout的小吃店 [英] Display Snackbar without CoordinatorLayout

问题描述

我已经使用CoordinatorLayout显示了Snackbar，但是在某些布局中我没有使用CoordinatorLayout布局，我想显示小吃栏，但是遇到了问题.

I have Displayed Snackbar using CoordinatorLayout but in some layout i did't used CoordinatorLayout layout and i want to display snackbar but faced problem with it.

我尝试了以下方法来在没有CoordinatorLayout的情况下实现小吃店，但它将显示以下结果.

I have tried following way to achieve snackbar without CoordinatorLayout but it will display following result.

Snackbar.make(getActivity().getWindow().getDecorView().getRootView(), "Testing Snackbar", Snackbar.LENGTH_LONG).show();

使用android 8.0 Oreo进行测试

Test it with android 8.0 Oreo

没有CoordinatorLayout可以实现Snackbar吗?

Is there any way to achieve Snackbar without CoordinatorLayout?

谢谢.

代码

public class FirstFragment extends Fragment {

RelativeLayout rootView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_first, container, false);

        Log.e("onCreateView", "onCreateView");

        rootView = (RelativeLayout)view.findViewById(R.id.rootView);
        setSnackBar(rootView, "Testing with answered");
        return view;
    }

public static void setSnackBar(View coordinatorLayout, String snackTitle) {
        Snackbar snackbar = Snackbar.make(coordinatorLayout, snackTitle, Snackbar.LENGTH_SHORT);
        snackbar.show();
        View view = snackbar.getView();
        TextView txtv = (TextView) view.findViewById(android.support.design.R.id.snackbar_text);
        txtv.setGravity(Gravity.CENTER_HORIZONTAL);
    }
}

推荐答案

public static void setSnackBar(View root, String snackTitle) {
  Snackbar snackbar = Snackbar.make(root, snackTitle, Snackbar.LENGTH_SHORT);
  snackbar.show();
  View view = snackbar.getView();
  TextView txtv = (TextView) view.findViewById(android.support.design.R.id.snackbar_text);
  txtv.setGravity(Gravity.CENTER_HORIZONTAL);
}

只需调用上述方法并传递任何父级布局，例如LinearLayout，RelativeLayout或ScrollView，即可:

Just call the above method and pass any parent layout such as LinearLayout, RelativeLayout or ScrollView, for example:

setSnackBar(layout,"This is your SnackBar");  //here "layout" is your parentView in a layout

不要忘记使用findViewById()查找视图.

Do not forget to find your view using findViewById().
