Android之Emoji表情开源库

上次做了一个表情的控件，不敢私藏，给大家分享
效果图如下，图片是新浪微博的，该有的功能应该都有了。

图片描述

这其实就是一个Fragment，所以用起来很方便，只要

FaceFragment faceFragment = FaceFragment.Instance();
getSupportFragmentManager().beginTransaction().add(R.id.Container,faceFragment).commit();

就可以显示效果图上的效果了。

FaceFragment源码如下：

public class FaceFragment extends Fragment implements View.OnClickListener {public static FaceFragment Instance() {FaceFragment instance = new FaceFragment();Bundle bundle = new Bundle();instance.setArguments(bundle);return instance;}ViewPager faceViewPager;EmojiIndicatorView faceIndicator;TextView faceRecentTv;TextView faceFirstSetTv;ArrayList<View> ViewPagerItems = new ArrayList<>();ArrayList<Emoji> emojiList;ArrayList<Emoji> recentlyEmojiList;private int columns = 7; //每一行的表情数量private int rows = 3;  //设置总共有几行private OnEmojiClickListener listener;private RecentEmojiManager recentManager;public void setListener(OnEmojiClickListener listener) {this.listener = listener;}@Overridepublic void onAttach(Activity activity) {if (activity instanceof OnEmojiClickListener) {this.listener = (OnEmojiClickListener) activity;}recentManager = RecentEmojiManager.make(activity);super.onAttach(activity);}@Overridepublic void onCreate(Bundle savedInstanceState) {emojiList = EmojiUtil.getEmojiList();try {//用SharedPerference来保存我们最近使用的表情if (recentManager.getCollection(RecentEmojiManager.PREFERENCE_NAME) != null) {recentlyEmojiList = (ArrayList<Emoji>) recentManager.getCollection(RecentEmojiManager.PREFERENCE_NAME);} else {recentlyEmojiList = new ArrayList<>();}} catch (IOException e) {e.printStackTrace();} catch (ClassNotFoundException e) {e.printStackTrace();}super.onCreate(savedInstanceState);}@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {View view = inflater.inflate(R.layout.fragment_face, container, false);faceViewPager = (ViewPager) view.findViewById(R.id.face_viewPager);faceIndicator = (EmojiIndicatorView) view.findViewById(R.id.face_indicator);faceRecentTv = (TextView) view.findViewById(R.id.face_recent);faceFirstSetTv = (TextView) view.findViewById(R.id.face_first_set);initViews();return view;}private void initViews() {initViewPager(emojiList);faceFirstSetTv.setSelected(true);faceFirstSetTv.setOnClickListener(this);faceRecentTv.setOnClickListener(this);}private void initViewPager(ArrayList<Emoji> list) {intiIndicator(list);ViewPagerItems.clear();for (int i = 0; i < getPagerCount(list); i++) {ViewPagerItems.add(getViewPagerItem(i, list));}FaceVPAdapter mVpAdapter = new FaceVPAdapter(ViewPagerItems);faceViewPager.setAdapter(mVpAdapter);faceViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {int oldPosition = 0;@Overridepublic void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}@Overridepublic void onPageSelected(int position) {faceIndicator.playBy(oldPosition, position);oldPosition = position;}@Overridepublic void onPageScrollStateChanged(int state) {}});}private void intiIndicator(ArrayList<Emoji> list) {faceIndicator.init(getPagerCount(list));}@Overridepublic void onClick(View v) {if(v.getId() == R.id.face_first_set){if (faceIndicator.getVisibility() == View.GONE) {faceIndicator.setVisibility(View.VISIBLE);}if (!faceFirstSetTv.isSelected()) {faceFirstSetTv.setSelected(true);initViewPager(emojiList);}faceRecentTv.setSelected(false);}else if (v.getId() == R.id.face_recent){if (faceIndicator.getVisibility() == View.VISIBLE) {faceIndicator.setVisibility(View.GONE);}if (!faceRecentTv.isSelected()) {faceRecentTv.setSelected(true);initViewPager(recentlyEmojiList);}faceFirstSetTv.setSelected(false);}}/*** 根据表情数量以及GridView设置的行数和列数计算Pager数量** @return*/private int getPagerCount(ArrayList<Emoji> list) {int count = list.size();return count % (columns * rows - 1) == 0 ?

}

你可以在EmojiUtil这个类中定义你的emoji编码去符合你的项目需求以及你需要在TextView中显示的Span大小。

public class EmojiUtil {private static ArrayList<Emoji> emojiList;public static ArrayList<Emoji> getEmojiList() {if (emojiList == null) {emojiList = generateEmojis();}return emojiList;}private static ArrayList<Emoji> generateEmojis() {ArrayList<Emoji> list = new ArrayList<>();for (int i = 0; i < EmojiResArray.length; i++) {Emoji emoji = new Emoji();emoji.setImageUri(EmojiResArray[i]);emoji.setContent(EmojiTextArray[i]);list.add(emoji);}return list;}public static final int[] EmojiResArray = {R.drawable.d_aini,R.drawable.d_aoteman,R.drawable.d_baibai,R.drawable.d_beishang,R.drawable.d_bishi,R.drawable.d_bizui,R.drawable.d_chanzui,R.drawable.d_chijing,R.drawable.d_dahaqi,R.drawable.d_dalian,R.drawable.d_ding,R.drawable.d_doge,R.drawable.d_feizao,R.drawable.d_ganmao,R.drawable.d_guzhang,R.drawable.d_haha,R.drawable.d_haixiu,R.drawable.d_han,R.drawable.d_hehe,R.drawable.d_heixian,R.drawable.d_heng,R.drawable.d_huaxin,R.drawable.d_jiyan,R.drawable.d_keai,R.drawable.d_kelian,R.drawable.d_ku,R.drawable.d_kun,R.drawable.d_landelini,R.drawable.d_lei,R.drawable.d_madaochenggong,R.drawable.d_miao,R.drawable.d_nanhaier,R.drawable.d_nu,R.drawable.d_numa,R.drawable.d_numa,R.drawable.d_qian,R.drawable.d_qinqin,R.drawable.d_shayan,R.drawable.d_shengbing,R.drawable.d_shenshou,R.drawable.d_shiwang,R.drawable.d_shuai,R.drawable.d_shuijiao,R.drawable.d_sikao,R.drawable.d_taikaixin,R.drawable.d_touxiao,R.drawable.d_tu,R.drawable.d_tuzi,R.drawable.d_wabishi,R.drawable.d_weiqu,R.drawable.d_xiaoku,R.drawable.d_xiongmao,R.drawable.d_xixi,R.drawable.d_xu,R.drawable.d_yinxian,R.drawable.d_yiwen,R.drawable.d_youhengheng,R.drawable.d_yun,R.drawable.d_zhajipijiu,R.drawable.d_zhuakuang,R.drawable.d_zhutou,R.drawable.d_zuiyou,R.drawable.d_zuohengheng,R.drawable.f_geili,R.drawable.f_hufen,R.drawable.f_jiong,R.drawable.f_meng,R.drawable.f_shenma,R.drawable.f_v5,R.drawable.f_xi,R.drawable.f_zhi,R.drawable.h_buyao,R.drawable.h_good,R.drawable.h_haha,R.drawable.h_lai,R.drawable.h_ok,R.drawable.h_quantou,R.drawable.h_ruo,R.drawable.h_woshou,R.drawable.h_ye,R.drawable.h_zan,R.drawable.h_zuoyi,R.drawable.l_shangxin,R.drawable.l_xin,R.drawable.o_dangao,R.drawable.o_feiji,R.drawable.o_ganbei,R.drawable.o_huatong,R.drawable.o_lazhu,R.drawable.o_liwu,R.drawable.o_lvsidai,R.drawable.o_weibo,R.drawable.o_weiguan,R.drawable.o_yinyue,R.drawable.o_zhaoxiangji,R.drawable.o_zhong,R.drawable.w_fuyun,R.drawable.w_shachenbao,R.drawable.w_taiyang,R.drawable.w_weifeng,R.drawable.w_xianhua,R.drawable.w_xiayu,R.drawable.w_yueliang,};public static final String[] EmojiTextArray = {"[爱你]","[奥特曼]","[拜拜]","[悲伤]","[鄙视]","[闭嘴]","[馋嘴]","[吃惊]","[哈欠]","[打脸]","[顶]","[doge]","[肥皂]","[感冒]","[鼓掌]","[哈哈]","[害羞]","[汗]","[微笑]","[黑线]","[哼]","[色]","[挤眼]","[可爱]","[可怜]","[酷]","[困]","[白眼]","[泪]","[马到成功]","[喵喵]","[男孩儿]","[怒]","[怒骂]","[女孩儿]","[钱]","[亲亲]","[傻眼]","[生病]","[草泥马]","[失望]","[衰]","[睡]","[思考]","[太开心]","[偷笑]","[吐]","[兔子]","[挖鼻]","[委屈]","[笑cry]","[熊猫]","[嘻嘻]","[嘘]","[阴险]","[疑问]","[右哼哼]","[晕]","[炸鸡啤酒]","[抓狂]","[猪头]","[最右]","[左哼哼]","[给力]","[互粉]","[囧]","[萌]","[神马]","[威武]","[喜]","[织]","[NO]","[good]","[haha]","[来]","[OK]","[拳头]","[弱]","[握手]","[耶]","[赞]","[作揖]","[伤心]","[心]","[蛋糕]","[飞机]","[干杯]","[话筒]","[蜡烛]","[礼物]","[绿丝带]","[围脖]","[围观]","[音乐]","[照相机]","[钟]","[浮云]","[沙尘暴]","[太阳]","[微风]","[鲜花]","[下雨]","[月亮]",};static {emojiList = generateEmojis();}public static int calculateInSampleSize(BitmapFactory.Options options,int reqWidth, int reqHeight) {// 源图片的高度和宽度final int height = options.outHeight;final int width = options.outWidth;int inSampleSize = 1;if (height > reqHeight || width > reqWidth) {// 计算出实际宽高和目标宽高的比率final int heightRatio = Math.round((float) height / (float) reqHeight);final int widthRatio = Math.round((float) width / (float) reqWidth);// 选择宽和高中最小的比率作为inSampleSize的值，这样可以保证最终图片的宽和高// 一定都会大于等于目标的宽和高。inSampleSize = heightRatio < widthRatio ?
