首先有2个对话框,没有设置过密码,需要设置dialog_set_password.xml,用户设置过密码,不需要设置,直接输入密码dialog_input_password.xml,
设置对话框dialog_set_password.xml
<?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" > <textview android:id="@+id/textview1" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:textcolor="@color/black" android:textsize="20sp" android:background="#66ff00" android:text="设置密码" android:padding="10dp" /> <edittext android:id="@+id/et_password" android:layout_width="match_parent" android:layout_height="wrap_content" android:inputtype="textpassword" android:hint="请输入密码" /> <edittext android:id="@+id/et_password_confirm" android:layout_width="match_parent" android:layout_height="wrap_content" android:inputtype="textpassword" android:hint="请再次输入密码" /> <linearlayout android:layout_width="match_parent" android:layout_height="wrap_content" > <button android:id="@+id/btn_ok" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="确定" /> <button android:id="@+id/btn_cancle" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="取消" /> </linearlayout> </linearlayout>
输入对话框dialog_input_password.xml,
<?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" > <textview android:id="@+id/textview1" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:textcolor="@color/black" android:textsize="20sp" android:background="#66ff00" android:text="输入密码" android:padding="10dp" /> <edittext android:id="@+id/et_password" android:layout_width="match_parent" android:layout_height="wrap_content" android:inputtype="textpassword" android:hint="请输入密码" /> <linearlayout android:layout_width="match_parent" android:layout_height="wrap_content" > <button android:id="@+id/btn_ok" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="确定" /> <button android:id="@+id/btn_cancle" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="取消" /> </linearlayout> </linearlayout>
业务逻辑并实现md5加密
