android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<com.captcha.CaptchaView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
label:captchaHeight="56dp"
label:captchaWidth="56dp"
label:inputMode="number"
label:number="4"/>
</LinearLayout>

| label:number | 验证码可输入的个数 |
| android:textColor | 字体颜色 |
| android:textSize | 字体大小 |
| android:gravity | CaptchaView 位置 |
| label:captchaWidth | 输入框的宽度 |
| label:captchaHeight | 输入框的高度 |
| label:dividerWidth | 输入框的间距 |

代码中设置
CaptchaView captchaView = (CaptchaView) findViewById(R.id.captchaView);
//设置间距
captchaView.setDivideWidth(20);
//设置输入框个数
captchaView.setNumber(5);
//设置显示位置
captchaView.setGravity(Gravity.CENTER);
//输入类型过滤，如果需指定 digits，这里的InputType必须为CaptchaView.INPUT_TYPE_NUMBER_TEXT才起作用
captchaView.setInputType(CaptchaView.INPUT_TYPE_NUMBER_TEXT, "1234efcsf*");
添加回调
captchaView.setOnInputCompleteListener(new CaptchaView.OnInputCompleteCallback() {
@Override
public void onInputCompleteListener(String captcha) {
// 输入完成回调
}
@Override
public void onError(String error) {
// InputType必须为CaptchaView.INPUT_TYPE_NUMBER_TEXT，才回调
// error 为不在 digits 中的字符
}
});
