如何禁用 snackbar 滑动以取消行为

Question

我想禁用滑动以消除 snackbar 我试过的行为很多事情对我都不起作用，任何人都建议我如何实现这一点，这是我试过的

final Snackbar snackbar = Snackbar
                .make(main_content, getResources().getString(R.string.no_internet), Snackbar.LENGTH_INDEFINITE);
        snackbar.setActionTextColor(Color.BLACK);

        View snackbarView = snackbar.getView();
        snackbarView.setBackgroundColor(Color.WHITE);
        TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
        textView.setTextColor(Color.BLACK);
       // textView.setTypeface(fontLight);
        snackbar.setAction("RETRY", new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                apiAccess();
            }
        });


        snackbar.show();

这是我的小吃店代码我已经尝试了两件事：

1

((android.support.design.widget.CoordinatorLayout.LayoutParams) snackbar.getView().getLayoutParams()).setBehavior(null);

在 snackbar.show(); 方法之后，但没有奏效。

2

main_content.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
                    @Override
                    public void onGlobalLayout() {
                        ViewGroup.LayoutParams lp = main_content.getLayoutParams();
                        if (lp instanceof CoordinatorLayout.LayoutParams) {
                            ((CoordinatorLayout.LayoutParams) lp).setBehavior(new DisableSwipeBehavior());
                            main_content.setLayoutParams(lp);
                        }
                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                            main_content.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                        } else {
                            //noinspection deprecation
                            main_content.getViewTreeObserver().removeGlobalOnLayoutListener(this);
                        }
                    }
                });

        public class DisableSwipeBehavior extends SwipeDismissBehavior<Snackbar.SnackbarLayout> {
        @Override
        public boolean canSwipeDismissView(@NonNull View view) {
            return false;
        }
    }

在上面的代码中 main_content 是我的 CoordinatorLayout。

Answer 1

试试这个：

Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView();
    snackbar.setDuration(Snackbar.LENGTH_INDEFINITE);
    snackbar.show();
    layout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            ViewGroup.LayoutParams lp = layout.getLayoutParams();
            if (lp instanceof CoordinatorLayout.LayoutParams) {
                ((CoordinatorLayout.LayoutParams) lp).setBehavior(new DisableSwipeBehavior());
                layout.setLayoutParams(lp);
            }
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                layout.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            } else {
                //noinspection deprecation
                layout.getViewTreeObserver().removeGlobalOnLayoutListener(this);
            }
        }
    });

DisableSwipeBehavior 所在位置：

public class DisableSwipeBehavior extends SwipeDismissBehavior<Snackbar.SnackbarLayout> {
    @Override
    public boolean canSwipeDismissView(@NonNull View view) {
        return false;
    }
}
