How to configure snackBar layout?

Question

Is there a way to change the snackBar layout to a custom view?

Now it turns black, and we can change the background color. But I don’t know how to inflate a new layout correctly and make it a snackBars backdrop?

Thank...

Answer 1

The snack bar does not allow you to customize the layout. However, as Primoz990 suggested, you can get a Snackbar view. The getView function returns Snackbar.SnackbarLayout, which is a horizontal LinearLayout object whose children are TextView and Button. To add your own view to Snackbar, you just need to hide the TextView and add View to Snackbar.SnackbarLayout.

// Create the Snackbar Snackbar snackbar = Snackbar.make(containerLayout, "", Snackbar.LENGTH_LONG); // Get the Snackbar layout view Snackbar.SnackbarLayout layout = (Snackbar.SnackbarLayout) snackbar.getView(); // Hide the text TextView textView = (TextView) layout.findViewById(android.support.design.R.id.snackbar_text); textView.setVisibility(View.INVISIBLE); // Inflate our custom view View snackView = mInflater.inflate(R.layout.my_snackbar, null); // Configure the view ImageView imageView = (ImageView) snackView.findViewById(R.id.image); imageView.setImageBitmap(image); TextView textViewTop = (TextView) snackView.findViewById(R.id.text); textViewTop.setText(text); textViewTop.setTextColor(Color.WHITE); //If the view is not covering the whole snackbar layout, add this line layout.setPadding(0,0,0,0); // Add the view to the Snackbar layout layout.addView(snackView, 0); // Show the Snackbar snackbar.show();

Probably starting from 25.1.0 revision of Android Support Library

I am. Declare a custom layout in the values ​​/ layout folder.

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="wrap_content"> <Button android:id="@+id/snackbar_action" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="@dimen/design_snackbar_extra_spacing_horizontal" android:layout_marginStart="@dimen/design_snackbar_extra_spacing_horizontal" android:layout_gravity="center_vertical|right|end" android:paddingTop="@dimen/design_snackbar_padding_vertical" android:paddingBottom="@dimen/design_snackbar_padding_vertical" android:paddingLeft="@dimen/design_snackbar_padding_horizontal" android:paddingRight="@dimen/design_snackbar_padding_horizontal" android:visibility="gone" android:textColor="?attr/colorAccent" style="?attr/borderlessButtonStyle"/> <TextView android:gravity="center_vertical|right" android:id="@+id/snackbar_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:paddingTop="@dimen/design_snackbar_padding_vertical" android:paddingBottom="@dimen/design_snackbar_padding_vertical" android:paddingLeft="@dimen/design_snackbar_padding_horizontal" android:paddingRight="@dimen/design_snackbar_padding_horizontal" android:textAppearance="@style/TextAppearance.Design.Snackbar.Message" android:maxLines="@integer/design_snackbar_text_max_lines" android:layout_gravity="center_vertical|left|start" android:ellipsize="end"/> </LinearLayout> 

Tips:

• Use the @dimen/design_snackbar as recommended by your material development.
• Use ?attr/colorAccent to apply the application changes to Snackbar.

II. Extend the BaseTransientBottomBar class.

 public class final CustomSnackbar extends BaseTransientBottomBar<CustomSnackbar> { /** * Constructor for the transient bottom bar. * * @param parent The parent for this transient bottom bar. * @param content The content view for this transient bottom bar. * @param contentViewCallback The content view callback for this transient bottom bar. */ private CustomSnackbar(ViewGroup parent, View content, ContentViewCallback contentViewCallback) { super(parent, content, contentViewCallback); } } 

III. Add BaseTransientBottomBar.ContentViewCallback

 public class final CustomSnackbar ...{ ... private static class ContentViewCallback implements BaseTransientBottomBar.ContentViewCallback { // view inflated from custom layout private View content; public ContentViewCallback(View content) { this.content = content; } @Override public void animateContentIn(int delay, int duration) { // add custom *in animations for your views // eg original snackbar uses alpha animation, from 0 to 1 ViewCompat.setScaleY(content, 0f); ViewCompat.animate(content) .scaleY(1f).setDuration(duration) .setStartDelay(delay); } @Override public void animateContentOut(int delay, int duration) { // add custom *out animations for your views // eg original snackbar uses alpha animation, from 1 to 0 ViewCompat.setScaleY(content, 1f); ViewCompat.animate(content) .scaleY(0f) .setDuration(duration) .setStartDelay(delay); } } } 

IV. Add a Snackbar creation method with a custom layout and methods to populate it.

 public class final CustomSnackbar ...{ ... public static CustomSnackbar make(ViewGroup parent, @Duration int duration) { // inflate custom layout LayoutInflater inflater = LayoutInflater.from(parent.getContext()); View content = inflater.inflate(R.layout.snackbar_view, parent, false); // create snackbar with custom view ContentViewCallback callback= new ContentViewCallback(content); CustomSnackbar customSnackbar = new CustomSnackbar(parent, content, callback); // set snackbar duration customSnackbar.setDuration(duration); return customSnackbar; } // set text in custom layout public CustomSnackbar setText(CharSequence text) { TextView textView = (TextView) getView().findViewById(R.id.snackbar_text); textView.setText(text); return this; } // set action in custom layout public CustomSnackbar setAction(CharSequence text, final OnClickListener listener) { Button actionView = (Button) getView().findViewById(R.id.snackbar_action); actionView.setText(text); actionView.setVisibility(View.VISIBLE); actionView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { listener.onClick(view); // Now dismiss the Snackbar dismiss(); } }); return this; } } 

V. Create an instance of CustomSnackbar and call the show() method.

 CustomSnackbar customSnackbar = CustomSnackbar.make(rooView, CustomSnackbar.LENGTH_INDEFINITE); customSnackbar.setText("No network connection!"); customSnackbar.setAction("Retry", new View.OnClickListener() { @Override public void onClick(View v) { // handle click here } }); customSnackbar.show();

Full CustomSnackbar.class code:

 import android.support.annotation.NonNull; import android.support.design.widget.BaseTransientBottomBar; import android.support.v4.view.ViewCompat; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button; import android.widget.TextView; public class CustomSnackbar extends BaseTransientBottomBar<CustomSnackbar> { /** * Constructor for the transient bottom bar. * * @param parent The parent for this transient bottom bar. * @param content The content view for this transient bottom bar. * @param callback The content view callback for this transient bottom bar. */ private CustomSnackbar(ViewGroup parent, View content, ContentViewCallback callback) { super(parent, content, callback); } public static CustomSnackbar make(@NonNull ViewGroup parent, @Duration int duration) { final LayoutInflater inflater = LayoutInflater.from(parent.getContext()); final View content = inflater.inflate(R.layout.snackbar_view, parent, false); final ContentViewCallback viewCallback = new ContentViewCallback(content); final CustomSnackbar customSnackbar = new CustomSnackbar(parent, content, viewCallback); customSnackbar.setDuration(duration); return customSnackbar; } public CustomSnackbar setText(CharSequence text) { TextView textView = (TextView) getView().findViewById(R.id.snackbar_text); textView.setText(text); return this; } public CustomSnackbar setAction(CharSequence text, final View.OnClickListener listener) { Button actionView = (Button) getView().findViewById(R.id.snackbar_action); actionView.setText(text); actionView.setVisibility(View.VISIBLE); actionView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { listener.onClick(view); // Now dismiss the Snackbar dismiss(); } }); return this; } private static class ContentViewCallback implements BaseTransientBottomBar.ContentViewCallback { private View content; public ContentViewCallback(View content) { this.content = content; } @Override public void animateContentIn(int delay, int duration) { ViewCompat.setScaleY(content, 0f); ViewCompat.animate(content).scaleY(1f).setDuration(duration).setStartDelay(delay); } @Override public void animateContentOut(int delay, int duration) { ViewCompat.setScaleY(content, 1f); ViewCompat.animate(content).scaleY(0f).setDuration(duration).setStartDelay(delay); } } } 

Answer 3

XML method:

The source xml file used for Snackbar is this file:

design_layout_snackbar_include.xml

  <?xml version="1.0" encoding="utf-8"?> <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:ellipsize="end"/> <Button android:id="@+id/snackbar_action" android:layout_width="wrap_content" android:layout_height="wrap_content" android:visibility="gone" ... android:textColor="?attr/colorAccent" style="?attr/borderlessButtonStyle"/> </merge> 

So, to override this layout , you must write your own layout with the same android:id as in this and in your refs.xml file, which you should add this line:

 <resources xmlns:tools="http://schemas.android.com/tools"> .... <item name="design_layout_snackbar_include" tools:override="true" type="layout"> @layout/my_layout_snackbar </item> .... </resources> 

Answer 4

Answer: Do not configure Snackbar. It should not contain more elements than short text and one action. See the Google Content Development Guide .

UPDATE: If you still want to configure Snackbar, this is what I implemented in my application:

 //generate the snackbar Snackbar sb = Snackbar.make(rootView, snack.text, duration); //set te action button text color sb.setActionTextColor(mCurrentActivity.getResources().getColor(R.color.snack_text_action)); //Get the view of the snackbar View sbView = sb.getView(); //set background color sbView.setBackgroundColor(mCurrentActivity.getResources().getColor(backgroudResId)); //Get the textview of the snackbar text TextView textView = (TextView) sbView.findViewById(android.support.design.R.id.snackbar_text); //set text color textView.setTextColor(mCurrentActivity.getResources().getColor(R.color.snack_text)); //increase max lines of text in snackbar. default is 2. textView.setMaxLines(10); 

I have never tried, but with getting the root view of Snackbar, you could programmatically add new views to Snackbar.

Answer 5

Try using the following code.

 Snackbar snackbar = Snackbar.make(container, "No Internet Connection", Snackbar.LENGTH_LONG); View sbView = snackbar.getView(); sbView.setBackgroundColor(ContextCompat.getColor(this, R.color.colorPrimary)); snackbar.show(); 

Note:

container - the parent view of the layout.

Answer 6

I tried and it works!

  View custom = LayoutInflater.from(this).inflate(R.layout.custom_view, null); snackbar.getView().setPadding(0,0,0,0); ((ViewGroup) snackbar.getView()).removeAllViews(); ((ViewGroup) snackbar.getView()).addView(custom); TextView textView = custom.findViewById(R.id.text); View button = custom.findViewById(R.id.button); textView.setText("Your text here"); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // do something } }); 

Answer 7

You can try this library. This is the default wrapper for the android diner. https://github.com/ChathuraHettiarachchi/CSnackBar

 Snackbar.with(this,null) .type(Type.SUCCESS) .message("Profile updated successfully!") .duration(Duration.SHORT) .show(); 

or you can even use your own view,

 View view = getLayoutInflater().inflate(R.layout.custom_view, null); Snackbar.with(this,null) .type(Type.UPDATE) .contentView(view, 76) .duration(Duration.SHORT) .show(); 

Currently there is only a problem with custom layout, we need to pass the view height in dp as input

Answer 8

 private Snackbar showSnackbar() { // Create the Snackbar Snackbar snackbar = Snackbar.make(coordinatorLayout, "", length); // 15 is margin from all the sides for snackbar int marginFromSides = 15; float hei[![enter image description here][1]][1]ght = 100; //inflate view View snackView = getLayoutInflater().inflate(R.layout.snackbar_layout, null); // White background snackbar.getView().setBackgroundColor(Color.WHITE); // for rounded edges snackbar.getView().setBackground(getResources().getDrawable(R.drawable.round_edges)); Snackbar.SnackbarLayout snackBarView = (Snackbar.SnackbarLayout) snackbar.getView(); FrameLayout.LayoutParams parentParams = (FrameLayout.LayoutParams) snackBarView.getLayoutParams(); parentParams.setMargins(marginFromSides, 0, marginFromSides, marginFromSides); parentParams.height = (int) height; parentParams.width = FrameLayout.LayoutParams.MATCH_PARENT; snackBarView.setLayoutParams(parentParams); snackBarView.addView(snackView, 0); return snackbar; } final Snackbar snackbar = showSnackbar(mainLayout, 90, Snackbar.LENGTH_LONG, R.layout.snackbar_layout); snackbar.show(); View view = snackbar.getView(); TextView tv = (TextView) view.findViewById(R.id.snackbar_action); tv.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { snackbar.dismiss(); } }); 

Answer 9

To add an answer to Yakiv Mospan to make your own BaseTransientBottomBar from bottom to bottom like a Snackbar , copy this method from the Snackbar class to find a suitable parent for the BaseTransientBottomBar constructor.

 private static ViewGroup findSuitableParent(View view) { ViewGroup fallback = null; do { if (view instanceof CoordinatorLayout) { // We've found a CoordinatorLayout, use it return (ViewGroup) view; } else if (view instanceof FrameLayout) { if (view.getId() == android.R.id.content) { // If we've hit the decor content view, then we didn't find a CoL in the // hierarchy, so use it. return (ViewGroup) view; } else { // It not the content view but we'll use it as our fallback fallback = (ViewGroup) view; } } if (view != null) { // Else, we will loop and crawl up the view hierarchy and try to find a parent final ViewParent parent = view.getParent(); view = parent instanceof View ? (View) parent : null; } } while (view != null); // If we reach here then we didn't find a CoL or a suitable content view so we'll fallback return fallback; }
