Welcome to reprint, but please keep the original source of the article

The first blog, I apologize
to attach the final finished map, although some functions are not very mature

Face recognition

The first is the face recognition function. Many companies have made this feature for developers to choose from. I am using the face recognition technology of Face++, but now I can only upload pictures by calling the system camera to take pictures. Analyze the picture to obtain face information. You cannot directly obtain and analyze the face while previewing the camera.
This is the Developer Center of Face++ official website, you can refer to the API document
http://www.faceplusplus.com.cn/uc_home/
This is the code for face analysis

    private Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            switch (msg.what) {
                case PARSE_OK:

                    JSONObject rs = (JSONObject) msg.obj;
                    parseInfo(rs);
                    Log.i("MyTest", "---age-->" + age + "-----gender--" + gender + "----smiling--" + smiling);
                    emotionInfo.setVisibility(View.VISIBLE);
                    find_btn_submit.setVisibility(View.GONE);
                    emotionInfo.setText("检测结果如下：\n年龄：" + age + "\n性别：" + gender + "\n笑脸值：" + smiling);
                    noCamera.clearAnimation();
                    tips.clearAnimation();
                    tips.setText("下拉开启音乐之旅");
                    break;
                case PARSE_ERRO:
                    handler.post(new Runnable() {
                        @Override
                        public void run() {
                            Toast.makeText(FindMusicActivity.this, "请检查网络连接", Toast.LENGTH_SHORT).show();
                            tips.clearAnimation();
                            tips.setText("当前网络状况出了点问题，检查一下再来吧~\n下拉随机推荐音乐");
                            noCamera.clearAnimation();
                            noCamera.setImageResource(R.mipmap.get_face_fail);
                        }
                    });
                    break;
            }
        }


    };

    /**
     * 解析心情

    private void parseInfo(JSONObject obj) {
        try {
            JSONArray faces = obj.getJSONArray("face");
            int faceCounts = faces.length();
            if (faceCounts == 0) {
                Toast.makeText(FindMusicActivity.this, "不好意思，没有检测出来，请重新检测", Toast.LENGTH_SHORT).show();

            } else {
                JSONObject face = faces.getJSONObject(0);
                String sex = face.getJSONObject("attribute").getJSONObject("gender").getString("value");
                gender = "Male".equals(sex) ? "男" : "女";
                age = face.getJSONObject("attribute").getJSONObject("age").getInt("value");
                smiling = face.getJSONObject("attribute").getJSONObject("smiling").getDouble("value");

Play music online

The problem of playing music has been a headache for me for a long time, and I can’t find the interface. Many interfaces found on the Internet say they can be used but cannot parse the data. In the end, I still haven’t found a good interface, so I can only get it directly from the Internet. the 70 songs links stored in the class, and then loads and plays music from the network address
of songs link for the way: http://m.blog.csdn.net/blog/gikieng_tjsd/38750971
songs to play I actually wrote a friend , This process also has various problems, especially the service problem. It is always impossible to obtain the service, or the service cannot be cancelled, the music cannot be stopped, and it is not perfect until now. This is a remaining problem.

Other functions

Sidebar

The side slide bar uses the DrawLayout of the Android v4 package. I should not mention the usage of DrawLayout. I believe everyone knows it. The main thing is to pay attention to the position where it appears, otherwise an error will be reported.

gesture

There are a lot of gestures used in it, such as sliding up, down, long press, etc., which can be implemented with the Gesture class. I didn’t use this here. I used the View.OnTouchListener interface, and then in the OnTouch() method, the finger is on the screen. Touch to make a judgment. According to the different coordinates and timestamps when pressing and lifting, judge what operation is made, but this judgment is not very accurate and is not recommended.

Third-party login and sharing function

The third party uses ShareSDK, I believe I have used it as a developer. When I was working on this project, because it was the first time to develop with Android studio, I didn’t know how to add it. Later, I found a friend on the Internet for a very detailed tutorial. You can refer to
http://www.cnblogs. com/smyhvae/p/4585340.html

At this point, the function of the project is probably finished. The first time I write a blog, it may be messy, forgive me.
