验证码mob集成&本地验证生成&短信截获

1.本地自定义view生成验证码：

这个是实现代码：

public class YANZHENGMA extends View{    private Paint paint;    private int viewWidth;    private int viewHeight;    private String [] codes=new String[4];    public String[] getCodes() {        return codes;    }    public YANZHENGMA(Context context) {        super(context);        init();    }    public YANZHENGMA(Context context, AttributeSet attrs) {        super(context, attrs);        init();    }    public YANZHENGMA(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);        init();    }    private void init() {        paint = new Paint();        paint.setAntiAlias(true);        paint.setFakeBoldText(RandomUtil.getboolen());        paint.setTextSize(100);        paint.setStrokeWidth(10);        paint.setShader(null);        setBackgroundColor(RandomUtil.getBgRandomColor());        setOnClickListener(new OnClickListener() {            @Override            public void onClick(View v) {                invalidate();            }        });    }    @Override    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

//获取高度        viewWidth=getWidth();        viewHeight=getHeight();    }    @Override    protected void onDraw(Canvas canvas) {        super.onDraw(canvas);      //生成背景色        //生成随机干扰线        paint.setColor(RandomUtil.getTextRandomColor());        //int linenum=RandomUtil.getRandomInt(4);        for (int i = 0; i <4 ; i++) {            paint.setColor(RandomUtil.getTextRandomColor());            canvas.drawLine(RandomUtil.getRandomFloat(viewWidth),RandomUtil.getRandomFloat(viewHeight),RandomUtil.getRandomFloat(viewWidth),RandomUtil.getRandomFloat(viewHeight),paint);        }        //生成干扰点        int pointnum=RandomUtil.getRandomInt(20);        for (int i = 0; i <20 ; i++) {            paint.setColor(RandomUtil.getTextRandomColor());            canvas.drawPoint(RandomUtil.getRandomFloat(viewWidth),RandomUtil.getRandomFloat(viewHeight),paint);        }        //生成文字        for (int i = 0; i < 4; i++) {            paint.setTextSkewX(RandomUtil.getRandomFloat(1)-0.5f);            paint.setColor(RandomUtil.getTextRandomColor());            float textX= RandomUtil.getRandomFloat(4)+viewWidth/4*i+viewWidth/8;            float textY= RandomUtil.getRandomFloat(20)-10-10+viewHeight;            codes[i]=RandomUtil.getRandomText()+"";            canvas.drawText(codes[i] ,textX,textY,paint);        }    }}

这个是随机工具类：

public class RandomUtil {    static Random mRandom=new Random();    //生成随机字符串    public static char getRandomText() {        int i = mRandom.nextInt(42) + 48;        while (i > 57 && i < 65) {            i = mRandom.nextInt(42) + 48;        }        char tmp = (char) (i);        return tmp;    }    //生成背景色    public static int getBgRandomColor() {        int r = mRandom.nextInt(140) + 115;        int g = mRandom.nextInt(140) + 115;        int b = mRandom.nextInt(140) + 115;        return Color.rgb(r, g, b);    }    //字体颜色    public static int getTextRandomColor() {        int r = mRandom.nextInt(90) + 40;        int g = mRandom.nextInt(90) + 40;        int b = mRandom.nextInt(90) + 40;        return Color.rgb(r, g, b);    }    //android设置Typeface字体    public static Typeface getType(){        //Typeface.defaultFromStyle(Typeface)        return null;    }    //随机boolen    public static boolean getboolen() {        return mRandom.nextBoolean();    }    //随机int    public static int getRandomInt(int a) {     //   rand        return mRandom.nextInt(a);    }    //随机float    public static float getRandomFloat(int a) {        //   rand        return mRandom.nextInt(a*100)/100f;    }}

2.这个是第三方的短信验证码使用的是mob的第三方短信验证码

需要做的操作将arr包和第三方库导入

gradle文件中配置：

repositories {    flatDir{        dirs 'libs'    }}dependencies {    compile fileTree(include: ['*.jar'], dir: 'libs')    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {        exclude group: 'com.android.support', module: 'support-annotations'    })    compile 'com.android.support:appcompat-v7:25.3.1'    testCompile 'junit:junit:4.12'    compile files('libs/MobTools-2017.0321.1624.jar')    //短信验证码依赖    compile name:'SMSSDK-2.1.4',ext:'aar'    compile name:'SMSSDKGUI-2.1.4',ext:'aar'}

application中初始化

public class APP extends Application {    @Override    public void onCreate() {        super.onCreate();        SMSSDK.initSDK(this, "1e3249818fa90", "4f8cb6e6ea65cdfd878798701362f6aa");    }}

代码中使用打开登录（网上找的方法比较清晰）：

  public void getyanzhen(View view) {        //打开注册页面        RegisterPage registerPage = new RegisterPage();       // registerPage.        registerPage.setRegisterCallback(new EventHandler() {            public void afterEvent(int event, int result, Object data) {// 解析注册结果                if (result == SMSSDK.RESULT_COMPLETE) {                    @SuppressWarnings("unchecked")                    HashMap<String,Object> phoneMap = (HashMap<String, Object>) data;                    String country = (String) phoneMap.get("country");                    String phone = (String) phoneMap.get("phone");// 提交用户信息（此方法可以不调用）                    registerUser(country, phone);                }            }        });        registerPage.show(this);    }

3.自己写后台接入时，在app中获取验证码：

    private SmsObserver mSmsObserver;    private Handler mHandler = new Handler(){        @Override        public void handleMessage(Message msg) {            super.handleMessage(msg);            if(msg.what == 1) {                String code = (String) msg.obj;               // mSmsTV.setText(code);                Log.e( "handleMessage: ",code );            }        }    };    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mSmsObserver = new SmsObserver(this, mHandler);        Uri smsUri = Uri.parse("content://sms");        getContentResolver().registerContentObserver(smsUri, true, mSmsObserver);//注册短信uri的监    }    @Override    protected void onPause() {        super.onPause();        getContentResolver().unregisterContentObserver(mSmsObserver);    }

public class SmsObserver extends ContentObserver {    private Context mContext;    private Handler mHandler;//更新ui    public SmsObserver(Context context, Handler handler) {        super(handler);        mContext = context;        mHandler = handler;    }    @Override    public void onChange(boolean selfChange, Uri uri) {        super.onChange(selfChange, uri);        /* 收到一条短信，onChange()会执行两次，uri不同 */        if (uri.toString().equals("content://sms/raw")) {//未写入数据库，不进行任何操作            return;        } else {//此时已经写入数据库            Uri inboxUri = Uri.parse("content://sms/inbox");            /* 按照日期倒序排序 */            Cursor cursor = mContext.getContentResolver().query(inboxUri, null, null, null, "date desc");            if (cursor != null) {                if (cursor.moveToFirst()) {//游标移动到first位置                    /* 发件人的号码 */                    String address = cursor.getString(cursor.getColumnIndex("address"));                    /* 短信内容 */                    String body = cursor.getString(cursor.getColumnIndex("body"));                    Log.i("wyk", "address:" + address + ",body:" + body);                    /* 利用正则提取验证码（根据实际情况修改） */                    Pattern pattern = Pattern.compile("(\\d{6})");//提取六位数字                    Matcher matcher = pattern.matcher(body);//进行匹配                    if(matcher.find()){//匹配成功                        String code = matcher.group(0);                        Message msg = mHandler.obtainMessage(1, code);                        mHandler.sendMessage(msg);                        Log.i("wyk","code:"+code);                    }                }                cursor.close();            }        }    }}
