이제 많은 앱에서 결제 및 비밀번호 입력 기능을 위해 맞춤 숫자 키보드를 사용하므로 편리하고 실용적입니다. 다음 기사에서는 Android 위챗 결제 숫자 키보드 기능을 소개하는데, 이는 매우 좋습니다. 관심 있는 친구들, 함께 배워보세요
WeChat의 숫자 키보드를 모방하여 자신의 프로젝트에 직접 사용하는 방법을 배워 보세요
다음 렌더링을 먼저 보세요.
1. 사용자 정의 레이아웃
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content"> <!-- 输入键盘 --> <GridView android:id="@+id/gv_keybord" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:background="#bdbdbd" android:horizontalSpacing="1px" android:numColumns="3" android:verticalSpacing="1px" /> <View android:id="@+id/line" android:layout_width="match_parent" android:layout_height="1px" android:layout_above="@id/gv_keybord" android:background="#bdbdbd" /> <RelativeLayout android:id="@+id/layoutBack" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_above="@id/line" android:background="#f5f5f5" android:padding="10dp"> <ImageView android:id="@+id/imgBack" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:src="@mipmap/keyboard_back_img" /> </RelativeLayout> <View android:layout_width="match_parent" android:layout_height="1px" android:layout_above="@id/layoutBack" android:layout_marginTop="1dp" android:background="#bdbdbd" /> </RelativeLayout>
키보드 레이아웃은 기본적으로 4X3 그리드 레이아웃의 GridView입니다. 🎜>2. 숫자 키보드 콘텐츠 구현
