java - Android - Snackbar 覆盖我的 View

Question

为什么 Snackbar 遮住了我的视野

这是我的xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fullview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/dark_gray"
    >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1">

            <TextView
                android:id="@+id/reload"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:gravity="center"
                android:layout_centerInParent="true"
                android:text="@string/reload"
                android:visibility="visible" />

            <ProgressBar
                android:id="@+id/progressbar"
                style="?android:attr/progressBarStyleLarge"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_centerInParent="true"
                android:gravity="center"
                android:visibility="gone" />

            <android.support.v7.widget.RecyclerView
                android:id="@+id/complist"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"

                android:layout_gravity="center"

                android:fadeScrollbars="false" />
        </RelativeLayout>


        <LinearLayout
            android:id="@+id/buttons"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom"
            android:layout_margin="5dp"
            android:orientation="horizontal">

            <Button
                android:id="@+id/send"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_margin="5dp"
                android:layout_weight="1"
                android:background="@color/blue"
                android:text="@string/send"
                android:textColor="@android:color/white" />

            <Button
                android:id="@+id/cancel"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_margin="5dp"
                android:layout_weight="1"
                android:background="@color/green"
                android:text="@string/cancel"
                android:textColor="@android:color/white" />
        </LinearLayout>
    </LinearLayout>
</android.support.design.widget.CoordinatorLayout>

用于显示蛇条的java代码

 private CoordinatorLayout _CoordinatorLayout;

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.compition, null);

        _CoordinatorLayout = (CoordinatorLayout) v.findViewById(R.id.fullview);

}

Snackbar.make(_CoordinatorLayout , message , Snackbar.LENGTH_LONG).show();

这是截图

我错过了什么？？

Answer 1

documentation这里说:

Snackbars appear above all other elements on screen and only one can be displayed at a time.

因此，Snackbar 将覆盖您的 View ，就像 Toast 一样。
