CaptchaView是一個驗證碼长踊、邀請碼的自定義布局，是在 InputCodeLayout 的基礎(chǔ)上修改了原生系統(tǒng)鍵盤刪除鍵不起作用的問題、添加了自定義脫敏樣式和自定義digits過濾及回調(diào)丧枪。

如何使用
只需要在 build.gradle 的 dependencies 添加:
compile 'com.opensource:captchaview:1.0.3'
布局中配置
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:label="http://schemas.android.com/apk/res-auto"
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>
| 屬性 | 描述 |
|---|---|
| label:number | 驗證碼可輸入的個數(shù) |
| android:textColor | 字體顏色 |
| android:textSize | 字體大小 |
| android:gravity | CaptchaView 位置 |
| label:captchaWidth | 輸入框的寬度 |
| label:captchaHeight | 輸入框的高度 |
| label:dividerWidth | 輸入框的間距 |
| label:hasFocusBackground | 是否顯示獲取焦點時背景光涂，默認(rèn)顯示 unFocusBackground 背景 |
| label:focusBackground | 獲取焦點時背景 |
| label:unFocusBackground | 失去焦點時背景 |
| label:passwordTransformation | 不可見時樣式，如 ● 拧烦、*忘闻，不指定為可見顯示 |
| label:inputMode | 輸入模式，number 只可輸入數(shù)字恋博，text 任何齐佳，numberText 只可輸入數(shù)字和字母 |
代碼中設(shè)置
CaptchaView captchaView = (CaptchaView) findViewById(R.id.captchaView);
//設(shè)置間距
captchaView.setDivideWidth(20);
//設(shè)置輸入框個數(shù)
captchaView.setNumber(5);
//設(shè)置顯示位置
captchaView.setGravity(Gravity.CENTER);
//輸入類型過濾，如果需指定 digits债沮，這里的InputType必須為CaptchaView.INPUT_TYPE_NUMBER_TEXT才起作用
captchaView.setInputType(CaptchaView.INPUT_TYPE_NUMBER_TEXT, "1234efcsf*");
添加回調(diào)
captchaView.setOnInputCompleteListener(new CaptchaView.OnInputCompleteCallback() {
@Override
public void onInputCompleteListener(String captcha) {
// 輸入完成回調(diào)
}
@Override
public void onError(String error) {
// InputType必須為CaptchaView.INPUT_TYPE_NUMBER_TEXT炼吴，才回調(diào)
// error 為不在 digits 中的字符
}
});
