效果图：

步骤一：添加相应的依赖库 com.android.suppory:design:22.2.0

步骤二：实现布局

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:layout_marginTop="20dp"    android:orientation="vertical">    <Button        android:id="@+id/sa_bn_easy"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_alignParentStart="true"        android:layout_below="@+id/sa_bn_good"        android:layout_marginTop="46dp"        android:onClick="easyClick"        android:text="简单提示" />    <Button        android:id="@+id/sa_bn_good"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:onClick="noeasyClick"        android:text="使用Snackbar自带布局" />    <android.support.design.widget.CoordinatorLayout        android:id="@+id/container"        android:layout_width="match_parent"        android:layout_height="100dp"        android:layout_alignParentBottom="true">    </android.support.design.widget.CoordinatorLayout></RelativeLayout>

步骤三：逻辑代码

import android.graphics.Color;import android.os.Bundle;import android.support.design.widget.CoordinatorLayout;import android.support.design.widget.Snackbar;import android.view.View;import android.widget.TextView;import android.widget.Toast;import com.gmtx.example.mylibsexample.R;import com.lib.utils.myutils.app.BaseActivity;import com.lib.utils.myutils.util.V;/** * Created by huqing on 2015/10/10. */public class SnackbarDemo extends Activity{    Snackbar mSnackBar;    CoordinatorLayout mCoordinatorLayout;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.snackbar_acty);        mCoordinatorLayout = V.f(this, R.id.container);    }    public void easyClick(View v) {        Snackbar.make(mCoordinatorLayout, "简单的", Snackbar.LENGTH_LONG).show();    }    public void noeasyClick(View v) {        final Snackbar snackbar = Snackbar.make(mCoordinatorLayout, "第一次", Snackbar.LENGTH_LONG);        snackbar.setAction("关闭", new View.OnClickListener() {            @Override            public void onClick(View v) {                Toast.makeText(context, "关闭", Toast.LENGTH_LONG).show();            }        });        setSnackbarMessageTextColor(snackbar, Color.YELLOW, Color.GREEN);//左侧字体颜色        snackbar.show();    }    public static void setSnackbarMessageTextColor(Snackbar snackbar, int color, int color1) {        View view = snackbar.getView();        ((TextView) view.findViewById(R.id.snackbar_text)).setTextColor(color);        ((TextView) view.findViewById(R.id.snackbar_action)).setTextColor(color1);    }}

ps:Snackbar中的布局如下，所以颜色值设置的方法就很明了了

<merge xmlns:android="http://schemas.android.com/apk/res/android">     <TextView            android:id="@+id/snackbar_text"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_weight="1"            android:paddingTop="@dimen/snackbar_padding_vertical"            android:paddingBottom="@dimen/snackbar_padding_vertical"            android:paddingLeft="@dimen/snackbar_padding_horizontal"            android:paddingRight="@dimen/snackbar_padding_horizontal"            android:textAppearance="@style/TextAppearance.Design.Snackbar.Message"            android:maxLines="@integer/snackbar_text_max_lines"            android:layout_gravity="center_vertical|left|start"            android:ellipsize="end"/>     <TextView            android:id="@+id/snackbar_action"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_marginLeft="@dimen/snackbar_extra_spacing_horizontal"            android:layout_marginStart="@dimen/snackbar_extra_spacing_horizontal"            android:layout_gravity="center_vertical|right|end"            android:background="?attr/selectableItemBackground"            android:paddingTop="@dimen/snackbar_padding_vertical"            android:paddingBottom="@dimen/snackbar_padding_vertical"            android:paddingLeft="@dimen/snackbar_padding_horizontal"            android:paddingRight="@dimen/snackbar_padding_horizontal"            android:visibility="gone"            android:textAppearance="@style/TextAppearance.Design.Snackbar.Action"/> </merge>
