由于这个模块内容较多,篇幅较长,请耐心阅读。
“我”的模块分为四个部分
- [ ] 我的界面
- [ ] 设置界面
- [x] 修改密码界面
- [x] 设置密保和找回密码
一、修改密码
1、创建修改密码界面
在com.boxuegu.activity
包中,创建一个java类,命名为ModifyPswActivity
。在res/layout
文件夹下创建布局文件,命名为activity_modify_psw
。
2、修改密码界面代码——activity_modify_psw.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/register_bg">
<include layout="@layout/main_title_bar"/>
<EditText
android:id="@+id/et_original_psw"
android:layout_width="fill_parent"
android:layout_height="48dp"
android:layout_gravity="center_horizontal"
android:layout_marginLeft="35dp"
android:layout_marginRight="35dp"
android:layout_marginTop="35dp"
android:background="@drawable/register_user_name_bg"

android:layout_marginTop="15dp"
android:background="@drawable/register_selector"
android:text="保存"
android:textColor="@android:color/white"
android:textSize="18sp"/>
</LinearLayout>
3、修改密码界面逻辑代码——ModifyPswActivity.java
package com.boxuegu.activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.content.pm.ActivityInfo;
import com.boxuegu.R;
import com.boxuegu.utils.AnalysisUtils;
import com.boxuegu.utils.MD5Utils;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.text.TextUtils;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class ModifyPswActivity extends AppCompatActivity {
private TextView tv_main_title;
private TextView tv_back;
private EditText et_original_psw, et_new_psw, et_new_psw_again;
private Button btn_save;
private String originalPsw, newPsw, newPswAgain;
private String userName;
@Override
protected void onCreate(Bundle savedIntanceState){
super.onCreate(savedIntanceState);
//设置界面布局
setContentView(R.layout.activity_modify_psw);
//设置界面为竖屏
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
init();
userName = AnalysisUtils.readLoginUserName(this);
}
//获取界面控件并处理相关控件的点击事件
private void init(){
tv_main_title = (TextView) findViewById(R.id.tv_main_title);
tv_main_title.setText("修改密码");
tv_back = (TextView) findViewById(R.id.tv_back);
et_original_psw = (EditText) findViewById(R.id.et_original_psw);
et_new_psw = (EditText) findViewById(R.id.et_new_psw);
et_new_psw_again = (EditText) findViewById(R.id.et_new_psw_again);
btn_save = (Button) findViewById(R.id.btn_save);
tv_back.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ModifyPswActivity.this.finish();
}
});
//保存按钮的点击事件
btn_save.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
getEditString();
if (TextUtils.isEmpty(originalPsw)) {
Toast.makeText(ModifyPswActivity.this, "请输入原始密码",
Toast.LENGTH_SHORT).show();
return;
}else if (!MD5Utils.md5(originalPsw).equals(readPsw())) {
Toast.makeText(ModifyPswActivity.this, "输入的密码与原始密码不一致",
Toast.LENGTH_SHORT).show();
return;
}else if (MD5Utils.md5(newPsw).equals(readPsw())) {
Toast.makeText(ModifyPswActivity.this, "输入的新密码与原始的密码不能一致",
Toast.LENGTH_SHORT).show();
return;
}else if (TextUtils.isEmpty(newPsw)) {
Toast.makeText(ModifyPswActivity.this, "请输入新密码",
Toast.LENGTH_SHORT).show();
return;
}else if (TextUtils.isEmpty(newPswAgain)) {
Toast.makeText(ModifyPswActivity.this, "请再次输入新密码",
Toast.LENGTH_SHORT).show();
return;
}else if (!newPsw.equals(newPswAgain)) {
Toast.makeText(ModifyPswActivity.this, "两次输入的新密码不一致",
Toast.LENGTH_SHORT).show();
return;
} else {
Toast.makeText(ModifyPswActivity.this,"新密码设置成功",
Toast.LENGTH_SHORT).show();
modifyPsw(newPsw);
Intent intent = new Intent(ModifyPswActivity.this, LoginActivity.class);
startActivity(intent);
SettingActivity.instance.finish(); //关闭设置界面
ModifyPswActivity.this.finish(); //关闭本界面
}
}
});
}
//获取控件上的字符串
private void getEditString(){
originalPsw = et_original_psw.getText().toString().trim();
newPsw = et_new_psw.getText().toString().trim();
newPswAgain=et_new_psw_again.getText().toString().trim();
}
//修改登录成功时保存在SharedPreferences中的密码
private void modifyPsw(String newPsw){
String md5Psw = MD5Utils.md5(newPsw);
SharedPreferences sp = getSharedPreferences("loginInfo",MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit(); //获取编辑器
editor.putString(userName,md5Psw); //保存新密码
editor.commit(); //提交修改
}
//从SharedPreferences中读取原始密码
private String readPsw(){
SharedPreferences sp = getSharedPreferences("loginInfo", MODE_PRIVATE);
String spPsw = sp.getString(userName, "");
return spPsw;
}
}
4、修改设置界面代码
在设置界面逻辑代码(SettingActivity.java
)文件中找到init
方法,在注释//跳转到修改密码的界面
下方添加如下代码
Intent intent = new Intent(SettingActivity.this,ModifyPswActivity.class);
startActivity(intent);
二、设置密保和找回密码
1、创建设置密保和找回密码界面
在com.boxuegu.activity
包中,创建一个java类,命名为FindPswActivity
。在res/layout
文件夹下创建布局文件,命名为activity_find_psw
。将所需图片find_psw_icon.png
导入drawable
文件夹中。
2、创建设置密保和找回密码界面界面代码——activity_find_psw.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"

android:layout_marginLeft="35dp"
android:layout_marginRight="35dp"
android:layout_marginTop="15dp"
android:background="@drawable/register_selector"
android:text="验证"
android:textColor="@android:color/white"
android:textSize="18sp"/>

4、修改代码
(1)、修改登录界面
到登录界面逻辑代码(LoginActivity.java
)文件夹中找到init
方法。在注释//跳转到找回密码界面
下方添加如下代码
Intent intent = new Intent(LoginActivity.this, FindPswActivity.class);
startActivity(intent);
(2)、修改设置界面
到设置界面逻辑代码(SettingActivity.java
)文件夹中找到init
方法。在注释//跳转到设置密保界面
下方添加如下代码
Intent intent = new Intent(SettingActivity.this,FindPswActivity.class);
intent.putExtra("from","security");
startActivity(intent);
