Android SearchView基本用法

1.设置searchView会在Toolbar中显示,或者在普通布局中显示：

(1).在普通布局当中：

 /**
         * 设置searchView:
         */
        setSearchAttribute(searchView);
        setSearchColor(searchView);
        //设置搜索栏的默认提示
        searchView.setQueryHint("Leslie");
        //默认刚进去就打开搜索栏
        searchView.setIconified(false);
        //点击事件：
        searchView.setOnSearchClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(getActivity(), SearchActivity.class));
            }
        });
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                Toast.makeText(getContext(), "您输入的文本为" + query, Toast.LENGTH_SHORT).show();
                return true;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                return false;
            }
        });

（2）在meau中设置：

    /**
     * 设置menu:
     */
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        //找到searchView:
        getMenuInflater().inflate(R.menu.search_menu, menu);
        MenuItem item=menu.findItem(R.id.searchs);
        SearchView searchView= (SearchView) MenuItemCompat.getActionView(item);
        setSearchAttribute(searchView);
        setSearchColor(searchView);

        //点击事件：
        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                Toast.makeText(SearchActivity.this, "您输入的文本为" + query, Toast.LENGTH_SHORT).show();
                searchs=query;
                ShareMusicUtils.SONG_NAME=SplicingSearchs();
                //请求搜索对象有关内容：
                Retrofit retrofit = new Retrofit.Builder().baseUrl("http://169.254.206.92:3000/search/")
                        .addConverterFactory(GsonConverterFactory.create())
                        .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                        .build();
                SearchApi searchApi = retrofit.create(SearchApi.class);
                Observable myStar = searchApi.getSearchData(ShareMusicUtils.SONG_NAME)
                        .subscribeOn(Schedulers.io())
                        .observeOn(AndroidSchedulers.mainThread());
                Toast.makeText(SearchActivity.this, "asdasdasdsadasdasdsada", Toast.LENGTH_SHORT).show();
                myStar.subscribe(new Observer() {
                    @Override
                    public void onSubscribe(Disposable d) {

                    }

                    @Override
                    public void onNext(SearchBean searchBean) {
                        Toast.makeText(SearchActivity.this, searchBean.toString(), Toast.LENGTH_SHORT).show();
                        Log.i("222222222222222", searchBean.toString());
                        List songs = searchBean.getResult().getSongs();
                        articleLists.addAll(songs);
                        List mvs = searchBean.getResult().getMvs();
                        classLists.addAll(mvs);
                        List playlists = searchBean.getResult().getPlaylists();
                        musicLists.addAll(playlists);
                        Log.i("1111111111111", songs.toString());
                    }

                    @Override
                    public void onError(Throwable e) {

                    }

                    @Override
                    public void onComplete() {

                    }
                });
//                Intent intent=new Intent(SearchActivity.this, SearchResultActivity.class);
//                intent.putExtra("broad", (Serializable) articleLists);
//                intent.putExtra("classes", (Serializable) classLists);
//                intent.putExtra("article", (Serializable) musicLists);
//                startActivity(intent);
                return true;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                return false;
            }
        });
        return super.onCreateOptionsMenu(menu);
    }

 

2.下面是searchView的设置方法：

（1）设置SearchView属性：

 /**
     * 设置Searchview属性：
     */
    private SearchView setSearchAttribute(SearchView searchView) {
        //默认刚进去就打开搜索栏：
        searchView.setIconified(false);
        //敲掉消除按键，下划线：
        searchView.findViewById(android.support.v7.appcompat.R.id.search_plate).setBackground(null);
        searchView.findViewById(android.support.v7.appcompat.R.id.search_close_btn).setBackground(null);
        //设置字体颜色、大小、背景：
        android.support.v7.widget.SearchView.SearchAutoComplete textView = searchView.findViewById(R.id.search_src_text);
        textView.setTextColor(getResources().getColor(R.color.text_color_hint));
        textView.setHintTextColor(getResources().getColor(R.color.text_color_hint));
        textView.setTextSize(TypedValue.COMPLEX_UNIT_SP, 15);
        textView.setBackgroundResource(R.drawable.search_box);
        //自定义button背景：
        ImageView closeViewIcon = (ImageView) searchView.findViewById(R.id.search_close_btn);
        closeViewIcon.setImageDrawable(ContextCompat
                .getDrawable(getContext(), R.drawable.pinlun_send));
        //设置搜索图标在编辑框外，ture时在框内
        searchView.setIconifiedByDefault(true);
        return searchView;
    }

(2).设置光标：

    /**
     * 设置searchView光标：
     */
    private SearchView setSearchColor(SearchView searchView) {
        final EditText editText = (EditText) searchView.findViewById(R.id.search_src_text);
        try {
            Field fCursorDrawableRes = TextView.class
                    .getDeclaredField("mCursorDrawableRes");
            fCursorDrawableRes.setAccessible(true);
            int mCursorDrawableRes = fCursorDrawableRes.getInt(editText);
            Field fEditor = TextView.class.getDeclaredField("mEditor");
            fEditor.setAccessible(true);
            Object editor = fEditor.get(editText);
            Class clazz = editor.getClass();
            Field fCursorDrawable =
                    clazz.getDeclaredField("mCursorDrawable");
            fCursorDrawable.setAccessible(true);
            if (mCursorDrawableRes <= 0) {
                return searchView;
            }

            Drawable cursorDrawable =
                    ContextCompat.getDrawable(searchView.getContext(), mCursorDrawableRes);
            if (cursorDrawable == null) {
                return searchView;
            }
            Drawable tintDrawable = DrawableCompat.wrap(cursorDrawable);
            DrawableCompat.setTintList(tintDrawable,
                    //自定义的颜色
                    ColorStateList.valueOf(
                            ContextCompat.getColor(getContext(), R.color.text_color_normal)));
            Drawable[] drawables
                    = new Drawable[]{tintDrawable, tintDrawable};
            fCursorDrawable.set(editor, drawables);
        } catch (Throwable ignored) {
        }
        return searchView;
    }
