스낵바의 배경색을 변경하는 방법은 무엇입니까?

alertDialog의 Positive click 내 DialogFragment에 스낵바가 표시됩니다. 다음은 내 코드 스 니펫입니다.

Snackbar snackbar = Snackbar.make(view, "Please enter customer name", Snackbar.LENGTH_LONG)
                .setAction("Action", null);
View sbView = snackbar.getView();
sbView.setBackgroundColor(Color.BLACK);
snackbar.show();

dialogfragment의보기를 스낵바에 전달하고 있습니다. 배경색을 검정색으로 하시겠습니까? 어떻게 할 수 있습니까? DialogFragment에서 alertDialog를 반환하고 있습니다. 그리고 다음과 같이 대화에 설정하고있는 테마

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">

    <!-- Used for the buttons -->
    <item name="colorAccent">@color/accent</item>
    <!-- Used for the title and text -->
    <item name="android:textColorPrimary">@color/primary</item>
    <!-- Used for the background -->
    <item name="android:background">@color/white</item>
</style>

대화 상자의 배경색을 흰색으로 설정하고 있지만 스낵바에 배경색을 설정하여 재정의해야합니다.

다음과 같이 배경색을 설정해보십시오.

sbView.setBackgroundColor(ContextCompat.getColor(getActivity(), R.color.BLACK));

100 % 작동합니다!

당신은 이렇게 할 수 있습니다

Snackbar snackbar;
snackbar = Snackbar.make(view, "Message", Snackbar.LENGTH_SHORT);
View snackBarView = snackbar.getView();
snackBarView.setBackgroundColor(yourColor);
TextView textView = (TextView) snackBarView.findViewById(android.support.design.R.id.snackbar_text);
textView.setTextColor(textColor);
snackbar.show();

---

모든 스낵바에 대한 배경색을 정의하려면 design_snackbar_background_color리소스의 어딘가에 값을 재정의하면 됩니다. 예를 들면 :

<color name="design_snackbar_background_color" tools:override="true">@color/colorPrimaryLight</color>

벨로우 코드는 메시지의 텍스트 색상을 변경하는 데 유용합니다.

Snackbar snackbar = Snackbar.make(rootView, "Enter Your Message",Snackbar.LENGTH_SHORT);
View view = snackbar.getView();
TextView tv = (TextView)view.findViewById(android.support.design.R.id.snackbar_text);
tv.setTextColor(Color.RED);
snackbar.show();

두 번째 방법 : 활동 주제를 변경하여 색상을 변경할 수도 있습니다.

Kotlin version (with an extension) :

Create in a file (for exemple SnackbarExtension.kt) an extension :

fun Snackbar.withColor(@ColorInt colorInt: Int): Snackbar{
   this.view.setBackgroundColor(colorInt)
   return this
}

Next, in your Activity/Fragment, you'll be able to do this :

Snackbar
  .make(coordinatorLayout, message, Snackbar.LENGTH_LONG)
  .withColor(YOUR_COLOR)
  .show()

As none of the other answers provided a custom style override (that I consider one of the more update safe way to do that) I post here my solution.

I post a solution that already address the new AndroidX (support design 28) theme.

Provided that your application use a custom them calle MyAppTheme in your AndroidManifest.xml:

<application
        android:name=".MyApplicationName"
        android:allowBackup="true"
        android:icon="@mipmap/icon"
        android:roundIcon="@mipmap/icon_round"
        android:label="@string/app_name"
        android:theme="@style/MyAppTheme">

Create (if you haven't already) values/style.xml file overriding the theme used by your application:

<style name="MyAppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
    <item name="colorPrimary">@color/myColorPrimary</item>
    <item name="colorPrimaryDark">@color/myColorPrimaryDark</item>
    <item name="colorAccent">@color/myColorAccent</item>
    <item name="snackbarStyle">@style/MySnackBarStyle</item>
</style>

<!-- snackbar style -->
<style name="MySnackBarStyle" parent="Widget.MaterialComponents.Snackbar">
    <item name="android:background">@color/mySnackbarBackgroundColor</item>
</style>

and provide your colors in your values/colors.xml file

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="myColorPrimary">#008577</color>
    <color name="myColorPrimaryDark">#00574B</color>
    <color name="myColorAccent">#D81B60</color>
    <color name="mySnackbarBackgroundColor">#D81B60</color>
</resources>

It's too late but In case someone still needs help. Here is the working solution.

      Snackbar snackbar = Snackbar.make(mainView, text, Snackbar.LENGTH_LONG);
    View snackBarView = snackbar.getView();
    snackBarView.setBackgroundColor(context.getResources().getColor(R.color.btn_background_color));
    snackbar.show();

While Working with xamarin android I found out that ContextCompat.GetColor() returns Int but the setBackgroundColor() expects a Parameter of type Color. So here is how I got it working in my xamarin android project.

Snackbar snackbarview =  Snackbar.Make(toolbar, message, Snackbar.LengthLong);
View snckView = snackbarview.View;                
snckView.SetBackgroundColor(Color.ParseColor(GetString(Resource.Color.colorPrimary)));
snackbarview.Show();

I made a little utils class so I can easily make custom colored snackbars thru out the app.

package com.yourapppackage.yourapp;

import android.support.design.widget.Snackbar;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class SnackbarUtils {

    private int BACKGROUND_COLOR;
    private int TEXT_COLOR;
    private int BUTTON_COLOR;
    private String TEXT;


    public SnackbarUtils(String aText, int aBgColor, int aTextColor, int aButtonColor){
        this.TEXT = aText;
        this.BACKGROUND_COLOR = aBgColor;
        this.TEXT_COLOR = aTextColor;
        this.BUTTON_COLOR = aButtonColor;
    }

    public Snackbar snackieBar(){
        Snackbar snackie = Snackbar.make(MainActivity.getInstance().findViewById(android.R.id.content), TEXT, Snackbar.LENGTH_LONG);
        View snackView = snackie.getView();
        TextView snackViewText = (TextView) snackView.findViewById(android.support.design.R.id.snackbar_text);
        Button snackViewButton = (Button) snackView.findViewById(android.support.design.R.id.snackbar_action);
        snackView.setBackgroundColor(BACKGROUND_COLOR);
        snackViewText.setTextColor(TEXT_COLOR);
        snackViewButton.setTextColor(BUTTON_COLOR);
        return snackie;
    }
}

then to use it, like this any where in the app:

new SnackbarUtils("This is the text displayed", Color.RED, Color.BLACK, Color.YELLOW).snackieBar().setAction("OTAY", v -> { 
     //donothing
     }).show();

Put it in an Utility class:

public class Utility {
    public static void showSnackBar(Context context, View view, String text) {
        Snackbar sb = Snackbar.make(view, text, Snackbar.LENGTH_SHORT);
        sb.getView().setBackgroundColor(ContextCompat.getColor(context, R.color.colorAccent));
        sb.show();
    }
}

Using like this:

Utility.showSnackBar(getApplicationContext(), findViewById(android.R.id.content), "Add success!!!");

---

None of other solutions really worked for me. If I only set Snackbar's background color, the layout under TextView and Button was in default color. If I set TextView's background it did a little blink after SnackBar was shown. And layout around button was still in default color.

결국 나에게 가장 좋은 방법은 TextView의 부모 (SnackbarContentLayout)의 배경색을 변경하는 것임을 알았습니다. 이제 전체 스낵바의 색상이 제대로 표시되고 표시 될 때 깜박이지 않습니다.

snack = Snackbar.make(view, text, duration)
View view = snack.getView();
view.setBackgroundColor(BACKGROUND_COLOR);
TextView tv = view.findViewById(android.support.design.R.id.snackbar_text);
tv.setTextColor(TEXT_COLOR);
((SnackbarContentLayout) tv.getParent()).setBackgroundColor(BACKGROUND_COLOR);

---

기본적으로 제공된 솔루션에는 한 가지 단점이 있습니다. 그들은 스낵바의 모양을 변경하고 반경을 제거합니다.

개인적으로 그런 걸 선호 해

val snackbar = Snackbar.make(view, text, Snackbar.LENGTH_LONG);
val view = snackbar.getView();
val color = view.resources.getColor(colorId)
view.background.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)

---

public class CustomBar {

public static void show(View view, String message, boolean isLong) {
    Snackbar s = Snackbar.make(view, message, isLong ? Snackbar.LENGTH_LONG : Snackbar.LENGTH_SHORT);
    s.getView().setBackgroundColor(ContextCompat.getColor(view.getContext(), R.color.red_900));
    s.show();
}

public static void show(View view, @StringRes int message, boolean isLong) {
    Snackbar s = Snackbar.make(view, message, isLong ? Snackbar.LENGTH_LONG : Snackbar.LENGTH_SHORT);
    s.getView().setBackgroundColor(ContextCompat.getColor(view.getContext(), R.color.red_900));
    s.show();
}

}

---

setBackgroundResource() 잘 작동합니다.

Snackbar snackbar = Snackbar.make(view, text, Snackbar.LENGTH_LONG);
View sbView = snackbar.getView();
sbView.setBackgroundResource(R.color.background);
snackbar.show();
