Android development-simple login interface and Android login interface

Android development-simple login interface and Android login interface

Use the <EditText/> <TextView> <ImageButton/> component xml to develop the interface, and use findViewById and OnClickListener to bind events to the background:

Use the <RadioGroup> and <RadioButton> components to implement a single worker

The Code is as follows:

Xml code:

<? Xml version = "1.0" encoding = "UTF-8"?> <LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android"
Android: layout_width = "match_parent"
Android: layout_height = "match_parent"
Android: orientation = "vertical">
<! -- Account input -->
<TextView
Android: id = "@ + id/text01"
Android: layout_width = "fill_parent"
Android: layout_height = "wrap_content"
Android: text = "@ string/user"
/>
<EditText
Android: id = "@ + id/edt01"
Android: layout_width = "fill_parent"
Android: layout_height = "wrap_content"
Android: hint = "@ string/input"

<! -- Password Input -->

Android: layout_width = "fill_parent"
Android: layout_height = "wrap_content"
