Implementing SearchView as per the material design guidelines

GunnerFan picture GunnerFan · May 21, 2015 · Viewed 68.9k times · Source

I have been looking for ways to implement a searchview in the activity toolbar (actionbar) as per the material design guidelines.

On clicking on the search icon, the entire toolbar animates to have only the search EditText with white background with suggestions appearing in the main view instead of a drop down.

Here is a screenshot from the guidelines: enter image description here

Here is a gif from the Gmail Inbox implementation: enter image description here

I have been looking for code examples and tutorials but so far I have been unsuccesful. How do I go about doing this?

I tried several material SearchView libraries, but none of them worked good as the one from the support library, so I decided to redesign it, after a lot of work, I am pleased with the result:

enter image description here

Here is how you can do it:

1) Add SearchView item to your menu

<item
    android:id="@+id/m_search"
    android:icon="@drawable/ic_action_search"
    android:title="@string/search_title"
    app:actionLayout="@layout/search_view_layout"
    app:showAsAction="ifRoom|collapseActionView" />

Notice that I'm declaring actionLayout instead of actionViewClass, I figured that this is the only way to set SearchView theme separately from Toolbar theme.

search_view_layout.xml:

<android.support.v7.widget.SearchView
    android:id="@+id/search_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/SearchViewTheme" />

2) Add the custom SearchView theme to your styles, declare SearchView theme in your Toolbar theme as well:

<style name="SearchViewTheme" parent="Widget.AppCompat.SearchView.ActionBar">
    <item name="layout">@layout/toolbar_search_view</item>
    <item name="commitIcon">@drawable/ic_search_commit</item>
    <item name="colorControlNormal">@color/material_light_active_icon</item>
    <item name="colorControlHighlight">@color/material_ripple_light</item>
    <item name="autoCompleteTextViewStyle">@style/AutoCompleteTextViewStyle</item>
    <item name="suggestionRowLayout">@layout/search_view_suggestion_row</item>
    <item name="android:maxWidth">9999dp</item>
</style>

<style name="AutoCompleteTextViewStyle" parent="Widget.AppCompat.Light.AutoCompleteTextView">
    <item name="android:popupBackground">@drawable/search_suggestions_bg</item>
    <item name="android:popupElevation">0dp</item>
</style>

<style name="ToolbarTheme" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="searchViewStyle">@style/SearchViewTheme</item>
</style>

toolbar_search_view.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/search_bar"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:paddingEnd="8dp">

<!-- This is actually used for the badge icon *or* the badge label (or neither) -->
<TextView

            android:paddingStart="8dp"
            android:visibility="gone" />
    </LinearLayout>
</LinearLayout>

Notice that I added anchor dropdown view under the Toolbar view, so suggestions will get full screen width.

<android.support.design.widget.AppBarLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/appBar"

    android:layout_height="wrap_content">

    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:collapseIcon="@drawable/ic_search_collapse"
    app:popupTheme="@style/AppTheme.PopupOverlay"
    app:theme="@style/ToolbarTheme" />

<View
    android:id="@+id/anchor_dropdown"
    android:layout_width="match_parent"
    android:layout_height="0dp" />

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

search_view_suggestion_row.xml:

(change suggestion_divider visibility if you want divider between suggestions):

<!-- Icons come first in the layout, since their placement doesn't depend on

The suggestions background and the commit icon are custom made, the rest of the icons I used can be found at: https://material.io/icons/

ic_search_commit.xml:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:autoMirrored="true"
    android:viewportHeight="24.0"
    android:viewportWidth="24.0">
    <path
        android:fillColor="@color/active_icon_color"
        android:pathData="m18.364,16.95l-8.605,-8.605l7.905,-0l-0.007,-2.001l-11.314,0l0,11.314l1.994,-0l0.007,-7.898l8.605,8.605l1.414,-1.414z" />

search_suggestions_bg.xml:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <shape android:shape="rectangle">
        <padding android:top="0.5dp" />
        <stroke

<item>
    <shape android:shape="rectangle">
        <solid android:color="@color/cards_and_dialogs_color" />
    </shape>

Add following values to your colors.xml (add values-night only if you are using DayNight theme):

values/colors.xml

<color name="material_light_primary_text">#DE000000</color>
<color name="material_light_hint_text">#61000000</color>

<color name="active_icon_color">@android:color/white</color>
<color name="cards_and_dialogs_color">#424242</color>

3) Last part, make the magic happen in code:

Setup and initialize SearchView in your desired activity

private MenuItem mSearchItem;
private Toolbar mToolbar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    mToolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(mToolbar);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);

    mSearchItem = menu.findItem(R.id.m_search);

    MenuItemCompat.setOnActionExpandListener(mSearchItem, new MenuItemCompat.OnActionExpandListener() {
        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            // Called when SearchView is collapsing
            if (mSearchItem.isActionViewExpanded()) {
                animateSearchToolbar(1, false, false);
            }
            return true;
        }

        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            // Called when SearchView is expanding
            animateSearchToolbar(1, true, true);
            return true;
        }
    });

    return true;
}

public void animateSearchToolbar(int numberOfMenuIcon, boolean containsOverflow, boolean show) {

    mToolbar.setBackgroundColor(ContextCompat.getColor(this, android.R.color.white));
    mDrawerLayout.setStatusBarBackgroundColor(ContextCompat.getColor(this, R.color.quantum_grey_600));

    if (show) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            int width = mToolbar.getWidth() -
                    (containsOverflow ? getResources().getDimensionPixelSize(R.dimen.abc_action_button_min_width_overflow_material) : 0) -
                    ((getResources().getDimensionPixelSize(R.dimen.abc_action_button_min_width_material) * numberOfMenuIcon) / 2);
            Animator createCircularReveal = ViewAnimationUtils.createCircularReveal(mToolbar,
                    isRtl(getResources()) ? mToolbar.getWidth() - width : width, mToolbar.getHeight() / 2, 0.0f, (float) width);
            createCircularReveal.setDuration(250);
            createCircularReveal.start();
        } else {
            TranslateAnimation translateAnimation = new TranslateAnimation(0.0f, 0.0f, (float) (-mToolbar.getHeight()), 0.0f);
            translateAnimation.setDuration(220);
            mToolbar.clearAnimation();
            mToolbar.startAnimation(translateAnimation);
        }
    } else {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            int width = mToolbar.getWidth() -
                    (containsOverflow ? getResources().getDimensionPixelSize(R.dimen.abc_action_button_min_width_overflow_material) : 0) -
                    ((getResources().getDimensionPixelSize(R.dimen.abc_action_button_min_width_material) * numberOfMenuIcon) / 2);
            Animator createCircularReveal = ViewAnimationUtils.createCircularReveal(mToolbar,
                    isRtl(getResources()) ? mToolbar.getWidth() - width : width, mToolbar.getHeight() / 2, (float) width, 0.0f);
            createCircularReveal.setDuration(250);
            createCircularReveal.addListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    super.onAnimationEnd(animation);
                    mToolbar.setBackgroundColor(getThemeColor(MainActivity.this, R.attr.colorPrimary));
                    mDrawerLayout.setStatusBarBackgroundColor(getThemeColor(MainActivity.this, R.attr.colorPrimaryDark));
                }
            });
            createCircularReveal.start();
        } else {
            AlphaAnimation alphaAnimation = new AlphaAnimation(1.0f, 0.0f);
            Animation translateAnimation = new TranslateAnimation(0.0f, 0.0f, 0.0f, (float) (-mToolbar.getHeight()));
            AnimationSet animationSet = new AnimationSet(true);
            animationSet.addAnimation(alphaAnimation);
            animationSet.addAnimation(translateAnimation);
            animationSet.setDuration(220);
            animationSet.setAnimationListener(new Animation.AnimationListener() {
                @Override
                public void onAnimationStart(Animation animation) {

                }

                @Override
                public void onAnimationEnd(Animation animation) {
                    mToolbar.setBackgroundColor(getThemeColor(MainActivity.this, R.attr.colorPrimary));
                }

                @Override
                public void onAnimationRepeat(Animation animation) {

                }
            });
            mToolbar.startAnimation(animationSet);
        }
        mDrawerLayout.setStatusBarBackgroundColor(getThemeColor(MainActivity.this, R.attr.colorPrimaryDark));
    }
}

private boolean isRtl(Resources resources) {
    return resources.getConfiguration().getLayoutDirection() == View.LAYOUT_DIRECTION_RTL;
}

private static int getThemeColor(Context context, int id) {
    Resources.Theme theme = context.getTheme();
    TypedArray a = theme.obtainStyledAttributes(new int[]{id});
    int result = a.getColor(0, 0);
    a.recycle();
    return result;
}

Few things to notice about the code:

1) The animation will adjust it's start point based on your set of number of menu items and if the toolbar has overflow icon, it will detect if layout is LTR or RTL automatically.

2) I'm using navigation drawer activity, so I set StatusBar color to mDrawerLayout, if you are using regular activity, you can set StatusBar color this way:

getWindow().setStatusBarColor(ContextCompat.getColor(this, R.color.quantum_grey_600));

3) The circular reveal animation will only work on KitKat and above.
