工具栏搜索建议主题

Question

我正在尝试将搜索建议更改为"轻量级主题".我正在使用appcompat-v7:22.2.0库并阅读有关自定义搜索视图小部件(android.support.v7.widget.SearchView)的新功能.

第一部分

工具栏

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />

主旋律

<style name="Main.Theme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/red</item>
    <item name="colorPrimaryDark">@color/red_dark</item>
    <item name="searchViewStyle">@style/Main.Theme.SearchView</item>
</style>

SearchView主题

<style name="Main.Theme.SearchView" parent="Widget.AppCompat.Light.SearchView">
    <item name="voiceIcon">@mipmap/test_icon</item>
</style>

这样我就无法影响搜索视图.为了测试它,我正在更改搜索视图中的语音图标,并且它不会从默认值更改.

第二部分

第二个尝试是覆盖工具栏中的叠加主题:

叠加主题

<style name="Main.Theme.Overlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="searchViewStyle">@style/Main.Theme.SearchView</item>
</style>

这样我得到一些反馈,但我失去了"材料设计",特别是我的"旧"提示图标,并且它有下划线.我的最终目标是更改搜索建议行背景:

建议行布局

<item name="suggestionRowLayout">@layout/my_custom_layout</item>

我认为我很难实现这个目标......你能帮助我吗？

Answer 1

这就是我使用自己的搜索建议的方式......

这是我的CountriesFragment文件，仅显示建议中的所有国家/地区名称。

这里的技巧是我提供自定义视图来显示建议列表。

public class CountriesFragment extends Fragment {

    private boolean mSearchCheck;
    private SimpleCursorAdapter mAdapter;
    public static final String TEXT_FRAGMENT = "TEXT_FRAGMENT";
    public static final String CITY_NAME = "cityName";
    private LayoutInflater mInflater;
    private ViewGroup mainContainer;

    private static final String[] COUNTRIES = {
            "Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica",

    };

    public static CountriesFragment newInstance(String text) {
        CountriesFragment mFragment = new CountriesFragment();
        Bundle mBundle = new Bundle();
        mBundle.putString(TEXT_FRAGMENT, text);
        mFragment.setArguments(mBundle);
        return mFragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        loadHints();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_countries, container, false);
        mInflater = inflater;
        mainContainer = (ViewGroup) rootView.findViewById(R.id.container);
        //rootView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
        return rootView;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        setHasOptionsMenu(true);
    }

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        super.onCreateOptionsMenu(menu, inflater);
        inflater.inflate(R.menu.menu, menu);

        SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.menu_search));
        searchView.setQueryHint(this.getString(R.string.search));

        ((EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text))
                .setHintTextColor(getResources().getColor(R.color.nliveo_white));


        searchView.setSuggestionsAdapter(mAdapter);
        searchView.setOnQueryTextListener(onQuerySearchView);
        searchView.setOnSuggestionListener(onQuerySuggestion);

        menu.findItem(R.id.menu_add).setVisible(true);
        menu.findItem(R.id.menu_search).setVisible(true);

        mSearchCheck = false;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        switch (item.getItemId()) {

            case R.id.menu_add:
                addCountry();
                break;

            case R.id.menu_search:

                break;
        }
        return true;
    }

    private void addCountry() {
        final ViewGroup newView = (ViewGroup) mInflater.inflate(R.layout.country_row, mainContainer, false);
        final TextView countryName = (TextView) newView.findViewById(android.R.id.text1);
        countryName.setText(COUNTRIES[(int) (Math.random() * COUNTRIES.length)]);


        final Animation fadeIn = AnimationUtils.loadAnimation(getActivity(), R.anim.fade_in);
        final Animation fadeOut = AnimationUtils.loadAnimation(getActivity(), R.anim.fade_out);
        fadeIn.setFillAfter(false);
        fadeOut.setFillAfter(false);

        closeButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                newView.startAnimation(fadeOut);
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mainContainer.removeView(newView);
                    }
                }, fadeOut.getDuration());
            }
        });

        mainContainer.addView(newView, 0);
        newView.startAnimation(fadeIn);
    }

    private SearchView.OnQueryTextListener onQuerySearchView = new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            mSearchCheck = false;
            return false;
        }

        @Override

        }
    };

    private void giveSuggestions(String query) {
        final MatrixCursor cursor = new MatrixCursor(new String[]{BaseColumns._ID, CITY_NAME});
        for (int i = 0; i < COUNTRIES.length; i++) {
            if (COUNTRIES[i].toLowerCase().contains(query.toLowerCase()))
                cursor.addRow(new Object[]{i, COUNTRIES[i]});
        }
        mAdapter.changeCursor(cursor);
    }

    private SearchView.OnSuggestionListener onQuerySuggestion = new SearchView.OnSuggestionListener() {

        }

        @Override

    };

    private void loadHints() {
        final String[] from = new String[]{CITY_NAME};
        final int[] to = new int[]{android.R.id.text1};
        mAdapter = new SimpleCursorAdapter(getActivity(),
                R.layout.hint_row,
                null,
                from,
                to,
                CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
    }
}

这里是hint_row.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="48dp"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:background="@color/nliveo_green_colorPrimaryDark"
    android:textColor="@color/nliveo_white"
    android:paddingLeft="15dp"
    android:paddingRight="15dp"
    android:minHeight="?android:attr/listPreferredItemHeightSmall"
    android:elevation="3dp"
    android:alpha="0.7" />

具有 SearchView 的简单菜单文件。menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/menu_search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        android:icon="@mipmap/ic_search_white_24dp"
        app:showAsAction="ifRoom|collapseActionView"
        android:title="@string/search"/>
    <item
        android:id="@+id/menu_add"
        android:icon="@mipmap/ic_add_white_24dp"
        app:showAsAction="ifRoom"
        android:title="@string/add"/>

</menu>

我收到了这个美丽的建议......
