问题描述

我在使用新的底部栏时遇到了一些问题.
我不能强迫将快餐栏移动到底部栏上方(这是设计指南告诉我的方式，应该 https://www.google.com/design/spec/components/bottom-navigation.html#bottom-navigation-specs ).

I am facing some problems with new bottom bar.
I can't force to move the snackbar above the bottom bar (this is how design guideline told me should be https://www.google.com/design/spec/components/bottom-navigation.html#bottom-navigation-specs).

这是我的activity_main.xml

This is my activity_main.xml

    <android.support.v7.widget.Toolbar
        android:id="@+id/main_activity_toolbar"
        android:layout_width="match_parent"

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    <android.support.design.widget.FloatingActionButton

        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"

        android:layout_height="56dp"
        android:background="?attr/colorPrimary"
        />

</LinearLayout>

main_activity.java中的快餐栏看起来像这样

The snackbar in main_activity.java looks like this

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(findViewById(R.id.main_content), "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });

        android:layout_height="match_parent"

                android:layout_width="wrap_content"

                android:layout_gravity="end|bottom"
                android:layout_margin="@dimen/fab_margin"
                android:src="@drawable/ic_menu_gallery" />

        </android.support.design.widget.CoordinatorLayout>

        <android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="56dp"
            android:background="?attr/colorPrimary" />

    </LinearLayout>

</android.support.design.widget.CoordinatorLayout>

，小吃栏代码将为

Snackbar.make(findViewById(R.id.placeSnackBar), "Replace with your own action", Snackbar.LENGTH_LONG)
            .setAction("Action", null).show();
