由于这个模块内容较多,篇幅较长,请耐心阅读。
个人资料模块分为两个部分 个人资料 资料修改 一、个人资料 1、个人资料界面 (1)、创建个人资料界面 在com.buxuegu.activity
包中创建一个java类,命名为UserInfoActivity
。在res/layout
文件夹下创建一个布局文件,命名为activity_user_info
。
(2)、界面代码——activity_user_info.xml
2、创建UserBean
选中com.boxuegu
包,新建一个bean
包。在bean包中创建一个Java类,命名为UserBean
。代码如下
package com.boxuegu.bean;
public class UserBean {
public String userName; //用户名
public String nickName; //昵称
public String sex; //性别
public String signature; //签名
}
3、创建用户信息表
选中com.boxuegu
包,新建一个sqlite
包。在sqlite包中创建一个Java类,命名为QLiteHelper
。因为SQLiteHelper类继承
SQLiteOpenHelper类,需要修改主类
。代码如下
package com.boxuegu.sqlite;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
//SQLiteHelper类继承自SQLiteOpenHelper类
public class SQLiteHelper extends SQLiteOpenHelper {
public static final int DB_VERSION = 1; //数据库的版本
public static final String DB_NAME = "wordpress.db"; //数据库的名称
public static final String U_USERINFO = "userinfo"; //个人资料
public SQLiteHelper(Context context){
super(context,DB_NAME,null,DB_VERSION);
}
//创建数据库
@Override
public void onCreate(SQLiteDatabase db){
//创建用户信息表
db.execSQL("CREATE TABLE IF NOT EXISTS " + U_USERINFO + "( " +
"_id INTEGER PRIMARY KEY AUTOINCREMENT, "
+ "userName VARCHAR," //用户名
+ "nickName VARCHAR," //昵称
+ "sex VARCHAR," //性别
+ "signature VARCHAR" //签名
+ ")" );
}
//数据库升级 版本号增加 升级调用此方法
@Override
public void onUpgrade(SQLiteDatabase db,int oldVersion,int newVersion){
db.execSQL("DROP TABLE IF NOT EXISTS " + U_USERINFO);
onCreate(db);
}
}
4、创建DBUtils工具类
选中com.boxuegu.utils
包,创建一个Java类,命名为BUtilsr
。用于操作数据库。代码如下
package com.boxuegu.utils;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import com.boxuegu.bean.UserBean;
import com.boxuegu.sqlite.SQLiteHelper;
public class DBUtils {
private static SQLiteHelper helper;
private static SQLiteDatabase db;
private static DBUtils instance = null;
public DBUtils(Context context) {
helper = new SQLiteHelper(context);
//getWritableDatabase();可写的数据库对象
db = helper.getWritableDatabase();
}
public static DBUtils getInstance(Context context) {
if (instance == null) {
instance = new DBUtils(context);
}
return instance;
}
//保存用户个人资料信息
public void saveUserInfo(UserBean bean) {
ContentValues cv = new ContentValues();
cv.put("userName", bean.userName);
cv.put("nickName", bean.nickName);
cv.put("sex", bean.sex);
cv.put("signature", bean.signature);
db.insert(SQLiteHelper.U_USERINFO, null, cv);
}
//获取个人资料信息
public UserBean getUserInfo(String userName) {
//获取对应用户名的个人信息
String sql = "SELECT * FROM " + SQLiteHelper.U_USERINFO + " WHERE userName=?";
Cursor cursor = db.rawQuery(sql,new String[]{userName});
UserBean bean = null;
while (cursor.moveToNext()){
bean = new UserBean();
bean.userName=cursor.getString(cursor.getColumnIndex("userName"));
bean.nickName=cursor.getString(cursor.getColumnIndex("nickName"));
bean.sex=cursor.getString(cursor.getColumnIndex("sex"));
bean.signature=cursor.getString(cursor.getColumnIndex("signature"));
}
cursor.close();
return bean;
}
//修改资料
public void updateUserInfo(String key, String value, String userName) {
ContentValues cv = new ContentValues();
cv.put(key, value);
db.update(SQLiteHelper.U_USERINFO, cv, "userName = ?", new String[]{userName});
}
}
5、个人资料界面逻辑代码——UserInfoActivity.java
package com.boxuegu.activity;
import android.content.DialogInterface;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import android.graphics.Color;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.text.TextUtils;
import android.os.Bundle;
import android.view.View;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.Toast;
import com.boxuegu.R;
import com.boxuegu.bean.UserBean;
import com.boxuegu.utils.AnalysisUtils;
import com.boxuegu.utils.DBUtils;
public class UserInfoActivity extends AppCompatActivity implements View.OnClickListener {
private TextView tv_user_name;
private TextView tv_signature;
private RelativeLayout rl_signature;
private TextView tv_sex;
private RelativeLayout rl_sex;
private TextView tv_nickName;
private RelativeLayout rl_nickName;
private TextView tv_back;
private TextView tv_main_title;
private RelativeLayout rl_title_bar;
private String spUserName;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_info);
//设置界面为竖屏
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
spUserName = AnalysisUtils.readLoginUserName(this);
init();
initData();
setListener();
}
//初始化控件
private void init() {
tv_back = (TextView) findViewById(R.id.tv_back);
tv_main_title = (TextView) findViewById(R.id.tv_main_title);
tv_main_title.setText("个人资料");
rl_title_bar = (RelativeLayout) findViewById(R.id.title_bar);
rl_title_bar.setBackgroundColor(Color.parseColor("##FF9900"));
rl_nickName = (RelativeLayout) findViewById(R.id.rl_nickName);
tv_nickName = (TextView) findViewById(R.id.tv_nickName);
rl_sex = (RelativeLayout) findViewById(R.id.rl_sex);
tv_sex = (TextView) findViewById(R.id.tv_sex);
rl_signature = (RelativeLayout) findViewById(R.id.rl_signature);
tv_signature = (TextView) findViewById(R.id.tv_signature);
tv_user_name = (TextView) findViewById(R.id.tv_user_name);
}
//从数据库中获取数据
private void initData(){
UserBean bean = null;
bean = DBUtils.getInstance(this).getUserInfo(spUserName);
//首先判断一下数据库中是否有数据
if(bean ==null){
bean = new UserBean();
bean.userName = spUserName; //用户名不可以修改
bean.nickName = "这个是你的昵称";
//默认为男
bean.sex = "男";
bean.signature = "这个是你的签名";
//保存用户信息到数据库
DBUtils.getInstance(this).saveUserInfo(bean);
}
setValue(bean);
}
//为界面控件设置值
public void setValue(UserBean bean) {
tv_nickName.setText(bean.nickName);
tv_sex.setText(bean.sex);
tv_signature.setText(bean.signature);
tv_user_name.setText(bean.userName);
}
//设置界面的点击监听事件
private void setListener() {
tv_back.setOnClickListener(this);
rl_nickName.setOnClickListener(this);
rl_sex.setOnClickListener(this);
rl_signature.setOnClickListener(this);
}
//控件的点击事件
@Override
public void onClick(View v) {
switch (v.getId()){
//返回键的点击事件
case R.id.tv_back:
this.finish();
break;
//昵称的点击事件
case R.id.rl_nickName:
break;
//性别的点击事件
case R.id.rl_sex:
String sex = tv_sex.getText().toString();
sexDialog(sex);
break;
//签名的点击事件
case R.id.rl_signature:
break;
default:
break;
}
}
//修改性别的弹出框
private void sexDialog(String sex) {
int sexFlag = 0;
if("男".equals(sex)){
sexFlag = 0;
}else if("女".equals(sex)){
sexFlag = 1;
}
final String items[] = {"男","女"};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("性别"); //设置标题
builder.setSingleChoiceItems(items, sexFlag, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
Toast.makeText(UserInfoActivity.this,items[which],Toast.LENGTH_SHORT).show();;
setSex(items[which]);
}
});
builder.show();
}
//更新界面上的性别数据
private void setSex(String sex) {
tv_sex.setText(sex);
//更新数据库中的性别数据
DBUtils.getInstance(this).updateUserInfo("sex",sex,spUserName);
}
}
6、修改我的界面代码
个人资料界面是通过点击用户头像进行跳转的,找到MyInfoView.java
文件的initView()
方法,在注释//已登录跳转到个人资料界面
下方添加如下代码:
Intent intent = new Intent(mContext, UserInfoActivity.class);
mContext.startActivity(intent);
二、资料修改界面
1、个人资料修改界面
(1)、创建个人资料修改界面
在com.boxuegu.activity
包中创建一个Java类。命名为ChangeUserInfoActivity
。在res/layout
文件夹下面创建布局文件,命名为activity_change_user_info
。
(2)、导入界面图片
将所需界面图片info_delete.png
导入到drawable
文件夹中。
(3)、资料修改界面代码——activity_change_user_info.xml
2、资料修改界面逻辑代码——ChangeUserInfoActivity.java
package com.boxuegu.activity;
import android.content.Intent;
import android.content.pm.ActivityInfo;
import com.boxuegu.R;
import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.text.Editable;
import android.text.Selection;
import android.text.TextUtils;
import android.text.TextWatcher;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.Toast;
public class ChangeUserInfoActivity extends AppCompatActivity {
private TextView tv_main_title,tv_save;
private RelativeLayout rl_title_bar;
private TextView tv_back;
private String title,content;
private int flag; //flag为1时表示修改昵称,为2时表示修改签名
private EditText et_content;
private ImageView iv_delete;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_change_user_info);
//设置界面为竖屏
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
init();
}
private void init(){
//从个人资料界面传递过来的标题和内容
title = getIntent().getStringExtra("title");
content = getIntent().getStringExtra("content");
flag = getIntent().getIntExtra("flag",0);
tv_main_title = (TextView) findViewById(R.id.tv_main_title);
tv_main_title.setText(title);
rl_title_bar = (RelativeLayout) findViewById(R.id.title_bar);
rl_title_bar.setBackgroundColor(Color.parseColor("#FF9900"));
tv_back = (TextView) findViewById(R.id.tv_back);
tv_save = (TextView) findViewById(R.id.tv_save);
tv_save.setVisibility(View.VISIBLE);
et_content = (EditText) findViewById(R.id.et_content);
iv_delete = (ImageView) findViewById(R.id.iv_delete);
if (!TextUtils.isEmpty(content)){
et_content.setText(content);
et_content.setSelection(content.length());
}
contentListener();
tv_back.setOnClickListener(new android.view.View.OnClickListener(){
@Override
public void onClick(android.view.View v){
ChangeUserInfoActivity.this.finish();
}
});
iv_delete.setOnClickListener(new android.view.View.OnClickListener() {
@Override
public void onClick(android.view.View v) {
et_content.setText("");
}
});
tv_save.setOnClickListener(new android.view.View.OnClickListener() {
@Override
public void onClick(android.view.View view) {
Intent data = new Intent();
String etContent = et_content.getText().toString().trim();
switch (flag){
case 1:
if (!TextUtils.isEmpty(etContent)){
data.putExtra("nickName",etContent);
setResult(RESULT_OK,data);
Toast.makeText(ChangeUserInfoActivity.this,"保存成功",Toast.LENGTH_SHORT).show();
ChangeUserInfoActivity.this.finish();
}else {
Toast.makeText(ChangeUserInfoActivity.this,"昵称不能为空",Toast.LENGTH_SHORT).show();
}
break;
case 2:
if (!TextUtils.isEmpty(etContent)){
data.putExtra("signature",etContent);
setResult(RESULT_OK,data);
Toast.makeText(ChangeUserInfoActivity.this,"保存成功",Toast.LENGTH_SHORT).show();
ChangeUserInfoActivity.this.finish();
}else {
Toast.makeText(ChangeUserInfoActivity.this,"签名不能为空",Toast.LENGTH_SHORT).show();
}
break;
}
}
});
}
//监听个人资料修改界面输入的文字
public void contentListener(){
et_content.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
Editable editable = et_content.getText();
int len = editable.length();
if (len>0){ //输入的文本的长度
iv_delete.setVisibility(View.VISIBLE);
}else {
iv_delete.setVisibility(View.GONE);
}
switch (flag){
case 1: //1代表修改昵称
if (len>8){ //昵称最多8个文字,超过的部分需要进行截取
int selEndIndex = Selection.getSelectionEnd(editable);
String str = editable.toString();
//截取新字符串
String newStr = str.substring(0,8);
et_content.setText(newStr);
editable = et_content.getText();
//新字符串的长度
int newLen = editable.length();
//旧光标位置超过新字符串的位置
if (selEndIndex>newLen){
selEndIndex = editable.length();
}
//设置新光标所在位置
Selection.setSelection(editable,selEndIndex);
}
break;
case 2: //2代表修改签名
if (len>16){ //昵称最多16个文字,超过的部分需要进行截取
int selEndIndex = Selection.getSelectionEnd(editable);
String str = editable.toString();
//截取新字符串
String newStr = str.substring(0,16);
et_content.setText(newStr);
editable = et_content.getText();
//新字符串的长度
int newLen = editable.length();
//旧光标位置超过新字符串的位置
if (selEndIndex>newLen){
selEndIndex = editable.length();
}
//设置新光标所在位置
Selection.setSelection(editable,selEndIndex);
}
break;
default:
break;
}
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void afterTextChanged(Editable arg0) {
}
});
}
}
3、修改个人资料界面代码
(1)、找到UserInfoActivity.java
文件,在 private String spUserName;
后面添加以下代码:
private static final int CHANGE_NICKNAME = 1;//修改昵称的自定义常量
private static final int CHANGE_SIGNATURE = 2;//修改签名的自定义常量
(2)、找到UserInfoActivity.java
文件,创建一个enterActivityForResult
方法用来自定义跳转
//自定义跳转方法
private void enterActivityForResult(Class to,int requestCode,Bundle b){
Intent i = new Intent(this,to); //to标识需要跳转到的界面
i.putExtras(b); //b表示跳转时传递的参数
startActivityForResult(i,requestCode); //requestCode表示一个请求码
}
(3)、找到UserInfoActivity.java
文件,找到onClick()
方法,在注释//昵称的点击事件
下方添加如下代码:
String name = tv_nickName.getText().toString();//获取昵称控件上的数据
Bundle bdName = new Bundle();
bdName.putString("content",name); //传递界面上的昵称数据
bdName.putString("title","昵称"); //传递界面的标题
bdName.putInt("flag",1); //flag 传递1表示是昵称
//跳转到个人资料修改界面
enterActivityForResult(ChangeUserInfoActivity.class,CHANGE_NICKNAME,bdName);
(4)、找到UserInfoActivity.java
文件,找到onClick()
方法,在注释//签名的点击事件
下方添加如下代码:
String signature = tv_signature.getText().toString();//获取签名控件上的数据
Bundle bdSignature = new Bundle();
bdSignature.putString("content",signature);//传递界面上的签名数据
bdSignature.putString("title","签名"); //传递界面的标题
bdSignature.putInt("flag",2);//flag 传递2表示是签名
//跳转到个人资料修改界面
enterActivityForResult(ChangeUserInfoActivity.class,CHANGE_SIGNATURE,bdSignature);
(5)、找到UserInfoActivity.java
文件,在UserInfoActivity类
中重写onActivityResult()
方法,添加如下代码:
//资料修改以后回传数据到界面
private String new_info; //最新数据
@Override
protected void onActivityResult(int requestCode,int resultCode,Intent data){
super.onActivityResult(requestCode,resultCode,data);
switch (requestCode){
case CHANGE_NICKNAME:
if(data!=null){
new_info = data.getStringExtra("nickName");//从个人资料界面回传过来的数据
if(TextUtils.isEmpty(new_info)||new_info==null){
return;
}
tv_nickName.setText(new_info);
//更新数据库中的呢称字段
DBUtils.getInstance(UserInfoActivity.this).updateUserInfo("nickName", new_info,spUserName);
}
break;
case CHANGE_SIGNATURE:
if(data!=null){
new_info = data.getStringExtra("signature");//从个人资料界面回传过来的数据
if(TextUtils.isEmpty(new_info)||new_info==null){
return;
}
tv_signature.setText(new_info);
//更新数据库中的签名字段
DBUtils.getInstance(UserInfoActivity.this).updateUserInfo("signature", new_info,spUserName);
}
break;
}
}
