主要有兩種顯示樣式，在枚舉中定義了4個(gè)輸入框6個(gè)輸入框

基本調(diào)用代碼如下：

//ll_sms_input就是CustomSmsCodeInputLayoutll_sms_input.run {//里邊的配置可以自行選擇配置   setTopTipVisible(false)   setCurrentCenterLineVisible(true)   setBottomSmsTvVisible(true)   setShowInputNum(CustomSmsCodeInputLayout.InputLineNum.SIX)//這里加載的是六個(gè)輸入框   setCurrentIndexLineColor(resources.getColor(R.color.global_text_color_grey))   //設(shè)置輸入類型只能是數(shù)字   setInputType(InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_SIGNED)   showSoftInput()  }ll_sms_input.setOnInputListener()//做輸入完成后的監(jiān)聽ll_sms_input.setOnClickSmsCodeTvListener()//點(diǎn)擊重新獲取按鈕的監(jiān)聽

上述就是小編為大家分享的Android中怎么自定義一個(gè)驗(yàn)證碼輸入框了，如果剛好有類似的疑惑，不妨參照上述分析進(jìn)行理解。如果想知道更多相關(guān)知識(shí)，歡迎關(guān)注億速云行業(yè)資訊頻道。
