現在、多くのアプリで支払いやパスワード入力機能にカスタムの数字キーボードが使用されており、便利で実用的です。次の記事では、Android 模倣性の高い WeChat 決済テンキーボード機能を紹介します。これは非常に優れています。興味のある友達は一緒に学ぶことができます
WeChat の数字キーボードを模倣して自分のプロジェクトで直接使用する方法を学びましょう
まずレンダリングを見てみましょう:
1. レイアウトをカスタマイズします
<?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>
2. 数値キーボード コンテンツを実装します
