Android仿滴滴出行驗(yàn)證碼輸入框功能實(shí)例代碼
更新時間：2017年12月18日 09:15:02 作者：hydCoder
最近項(xiàng)目經(jīng)理交給我們組一個類似滴滴出行填寫驗(yàn)證碼的彈框功能，拿到這個項(xiàng)目需求真是把我忙暈了，下面通過本文給大家分享Android仿滴滴出行驗(yàn)證碼輸入框功能實(shí)例代碼，需要的朋友參考下吧
最近公司項(xiàng)目中有一個類似滴滴出行填寫驗(yàn)證碼的彈框，下面是我擼出來的效果：
中間的那個輸入密碼的6個框框其實(shí)就是用shape畫的背景，通過監(jiān)聽EditText獲取焦點(diǎn)來改變背景，廢話少說，直接上代碼吧。
2、效果實(shí)現(xiàn)
代碼內(nèi)容比較簡單，所以大家可以直接看代碼

public interface Listener {

} ··· styles.xml里添加自定義屬性
<declare-styleable name="vericationCodeInput">
<attr name="box" format="integer" />
<attr name="child_h_padding" format="dimension"/>
<attr name="child_v_padding" format="dimension"/>
<attr name="child_width" format="dimension"/>
<attr name="child_height" format="dimension"/>
<attr name="padding" format="dimension"/>
<attr name="box_bg_focus" format="reference"/>
<attr name="box_bg_normal" format="reference"/>
<attr name="inputType" format="string"/>
</declare-styleable>
輸入框獲取焦點(diǎn)時的背景
verification_edit_bg_focus.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFFFFF" />
<corners android:radius="8dip" />
<stroke
android:width="2dip"
android:color="@color/auxiliary_color" />
</shape>
輸入框沒有獲取焦點(diǎn)時的背景
verification_edit_bg_normal.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/white" />
<corners android:radius="8dip" />
<stroke
android:width="1dip"
android:color="@color/divide_color"/>
</shape>
在界面中使用
<com.sdalolo.genius.ui.view.VerificationCodeInput android:digits="1234567890" android:id="@+id/verificationCodeInput" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="25dp" android:layout_gravity="center_horizontal" ver:box="6" ver:box_bg_normal="@drawable/verification_edit_bg_normal" ver:box_bg_focus="@drawable/verification_edit_bg_focus" ver:child_h_padding="5dp" android:layout_centerInParent="true" android:layout_marginBottom="16dp"/>
然后對它設(shè)置輸入完成后的監(jiān)聽
verificationCodeInput.setOnCompleteListener(new VerificationCodeInput.Listener() {
@Override
public void onComplete(String content) {
btn_confirm.setEnabled(true);
btn_confirm.setBackgroundResource(R.drawable.btn_bg_shape_enable);
btn_confirm.setTextColor(Color.parseColor("#e4c16a"));
codeNum = content;
}
});
