初學 Android項目 {家庭理財通}

我也是一個初學Android的小白，在校大二項目希望對大家有幫助！

項目文件 項目文件中 有 密碼的Model、Dao、以及創建新密碼的Activity 只不過當時沒有實現。小伙伴們可以在系統設置中自己練習來完善功能
所以登錄時設定了初始密碼
密碼為 admin 小寫

eclipseJDK

Android 4.3	JDK1.8

使用 Genymotion 2.12 虛擬器 來模擬 Android 手機運行 源碼下載

文件樹

AccountTools 為彈窗工具類 使用時直接調用即可

AccountTools.java

代碼片.

package com.ds.accountsoft.tools; import com.ds.accountsoft.model.InAccount; import com.ds.accountsoft.model.OutAccount;import android.content.Context; import android.view.Gravity; import android.widget.Toast; public class AccountTools {private Context context;public static void showToast(Context context,String text){Toast t = Toast.makeText(context, text, Toast.LENGTH_LONG);t.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.TOP, 0, 333);t.show();}/**將新Account實例*/public static OutAccount checkOut(String str_money,String str_time,String str_type,String str_address,String str_mark){OutAccount out = new OutAccount();double money = 0 ;if(str_money != null && !str_money.equals("")){try{money = Double.valueOf(str_money).doubleValue();out.setMoney(money);}catch(Exception e){out.setMoney(0);}}if(str_time != null && !str_time.equals("")){out.setTime(str_time);}else{out.setTime("");}if(str_type != null && !str_type.equals("")){out.setType(str_type);}else{out.setType("");}if(str_address != null && !str_address.equals("")){out.setAddress(str_address);}else{out.setAddress("");}if(str_mark != null && !str_mark.equals("")){out.setMark(str_mark);}else{out.setMark("");}return out;}public static InAccount checkAdd(String str_money,String str_time,String str_type,String str_payfor,String str_mark){InAccount add = new InAccount();double money = 0 ;if(str_money != null && !str_money.equals("")){try{money = Double.valueOf(str_money).doubleValue();add.setMoney(money);}catch(Exception e){add.setMoney(0);}}if(str_time != null && !str_time.equals("")){add.setTime(str_time);}else{add.setTime("");}if(str_type != null && !str_type.equals("")){add.setType(str_type);}else{add.setType("");}if(str_payfor != null && !str_payfor.equals("")){add.setPayfor(str_payfor);}else{add.setPayfor("");}if(str_mark != null && !str_mark.equals("")){add.setMark(str_mark);}else{add.setMark("");}return add;} }

登錄界面樣式

需要先在strings.xml中添加所需要用到的 字段并定義一個name 以便使用 下面這是我定義的所有頁面中將使用的文字

strings.xml

<?xml version="1.0" encoding="utf-8"?> <resources><string name="app_name">家庭理財通</string><string name="action_settings">Settings</string><string name="hello_world">Hello world!</string><string name="txt_pwd">請輸入密碼：</string><string name="edit_hint">請輸入密碼....</string><string name="btn_login">登錄</string><string name="btn_exit">退出</string><string name="txt_out_title">新增支出</string><string name="txt_out_money">金額：</string><string name="txt_out_time">時間：</string><string name="txt_out_type">類別：</string><string name="txt_out_address">地點：</string><string name="txt_out_mark">備注：</string><string name="btn_save">保存</string><string name="btn_reset">取消</string><string name="hint_out_money">金額....</string><string name="hint_out_time">選擇時間....</string><string name="hint_out_type">選擇類別....</string><string name="hint_out_address">地址....</string><string name="hint_out_mark">備注....</string><string name="txt_add_title">新增收入</string><string name="txt_add_money">金&#160;&#160;&#160;&#160;額：</string><string name="txt_add_time">時&#160;&#160;&#160;&#160;間：</string><string name="txt_add_type">類&#160;&#160;&#160;&#160;別：</string><string name="txt_add_payfor">付款方：</string><string name="txt_add_mark">備&#160;&#160;&#160;&#160;注：</string><string name="hint_add_money">金額....</string><string name="hint_add_time">選擇時間....</string><string name="hint_add_type">類別....</string><string name="hint_add_payfor">付款方....</string><string name="hint_add_mark">備注....</string><string name="txt_myout_title">我的支出</string><string name="txt_myadd_title">我的收入</string><!-- 數據管理 --><string name="txt_manager_title">數據管理</string><string name="btn_manager_in">我的收入</string><string name="btn_manager_out">我的支出</string><string name="txt_edit_out_title">編輯支出</string><string name="txt_edit_add_title">編輯收入</string><string name="btn_delete">刪除</string><string name="btn_replace">修改</string><!-- 系統設置 --><string name="txt_password_title">系統設置</string><string name="btn_password_add">新增密碼</string><string name="btn_password_update">修改密碼</string><string name="txt_add_password_title">增加密碼</string><string name="txt_edit_password_title">修改密碼</string><string name="txt_input_password">輸入密碼：</string><string name="hint_input_password">請輸入密碼....</string><string name="txt_again_input_password">確認輸入：</string><string name="hint_again_input_password">請再次輸入密碼....</string><string name="txt_flag_title">收支便簽</string><string name="btn_flag_add">新增便簽</string><string name="btn_flag_update">修改便簽</string><string name="txt_add_flag_title">新增便簽</string><string name="txt_update_flag_title">編輯便簽</string><string name="hint_add_message">請輸入便簽....</string> </resources>

account_login.xml

代碼片.

<?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="match_parent" android:padding="20dp"android:background="@drawable/bgimg"><TextViewandroid:id="@+id/txt_pwd"android:text="@string/txt_pwd"android:textSize="20sp"android:layout_marginTop="20dp"android:layout_width="match_parent"android:layout_height="wrap_content"android:textStyle="bold"android:textColor="@color/steelblue"/><EditTextandroid:layout_marginTop="20dp"android:id="@+id/edit_pwd"android:layout_width="match_parent"android:layout_height="wrap_content"android:hint="@string/edit_hint"android:inputType="textPassword"android:textSize="16sp"android:layout_below="@id/txt_pwd"/><Buttonandroid:layout_marginTop="20dp"android:id="@+id/btn_login"android:text="@string/btn_login"android:layout_height="40dp"android:layout_width="match_parent"android:layout_below="@id/edit_pwd"android:layout_alignParentRight="true"/><Buttonandroid:id="@+id/btn_exit"android:text="@string/btn_exit"android:layout_height="40dp"android:layout_width="match_parent"android:layout_below="@id/btn_login"android:layout_alignParentRight="true"/> </RelativeLayout>

passwordDao.java

DBHelper.java

DBHelper.java 是在手機中創建數據庫與數據表
弊端 軟件如果卸載 在重新安裝數據將會消失不會保存

package com.ds.accountsoft.dao; import android.content.Context; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteDatabase.CursorFactory; import android.database.sqlite.SQLiteOpenHelper; public class DBHelper extends SQLiteOpenHelper{private static String DB_NAME = "db_account";private static int VERSION = 1;private static String TB_IN ="create table tb_in(_id Integer primary key autoincrement,money,time,type,payfor,mark)";private static String TB_OUT ="create table tb_out(_id Integer primary key autoincrement,money,time,type,address,mark)";private static String TB_FLAG ="create table tb_flag(_id Integer primary key autoincrement,message)";private static String TB_PWD ="create table tb_pwd(_id Integer primary key autoincrement,pwd)";public DBHelper(Context context){super(context,DB_NAME,null,VERSION);}public DBHelper(Context context, String name, CursorFactory factory,int version) {super(context, name, factory, version);}@Overridepublic void onCreate(SQLiteDatabase db) {db.execSQL(TB_IN);db.execSQL(TB_OUT);db.execSQL(TB_FLAG);db.execSQL(TB_PWD);}@Overridepublic void onUpgrade(SQLiteDatabase arg0, int oldversion, int newversion) {} }

Accout_LoginActivity.java

package com.ds.accountsoft.activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; import android.app.Activity; import android.content.Context; import android.content.Intent;import com.ds.accountsoft.dao.PasswordDao; import com.ds.accountsoft.model.Password; import com.ds.accountsoft.tools.*; public class Accout_LoginActivity extends Activity {private Context context = Accout_LoginActivity.this;private Button btn_login,btn_exit;private TextView txt_pwd;private EditText edit_pwd;private void bindView(){btn_login = (Button)findViewById(R.id.btn_login);btn_exit = (Button)findViewById(R.id.btn_exit);txt_pwd = (TextView)findViewById(R.id.txt_pwd);edit_pwd = (EditText)findViewById(R.id.edit_pwd);btn_login.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {String pwd = edit_pwd.getText()+"";if(pwd == null || pwd.equals("")){AccountTools.showToast(context, "請輸入密碼！");}else{if(pwd.equals("admin")){ //設置登錄密碼Intent intent = new Intent(context,AccountMainActivity.class);startActivity(intent);AccountTools.showToast(context, "進入主程序");}else{AccountTools.showToast(context, "密碼輸入錯誤請從新輸入");edit_pwd.setText("");}}}});btn_exit.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {finish();//退出此程序}});}protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.account_login);bindView();} }

AndroidMainifest.xml

AndroidMainifest.xml 實現開始主頁與各頁面跳轉

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.ds.accountsoft.activity"android:versionCode="1"android:versionName="1.0" ><uses-sdkandroid:minSdkVersion="15"android:targetSdkVersion="19" /><applicationandroid:allowBackup="true"android:icon="@drawable/ico"android:label="@string/app_name"android:theme="@style/AppTheme" ><activityandroid:name="com.ds.accountsoft.activity.Accout_LoginActivity"android:label="@string/app_name" ><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="android.intent.category.LAUNCHER" /></intent-filter></activity><activity android:name=".AccountMainActivity"/><!-- 應用主界面 --><activity android:name=".AccountAddOutActivity"/><!-- 新增支出 --><activity android:name=".AccountAddInActivity"/><!-- 新增收入--><activity android:name=".AccountMyOutActivity"/><!-- 我的支出 --><activity android:name=".AccountMyAddActivity"/><!-- 我的收入 --><activity android:name=".AccountManagerActivity"/><!-- 數據管理 --><activity android:name=".AccountEditOutActivity"/><!-- 修改新增支出 --><activity android:name=".AccountEditInActivity"/><!-- 修改新增收入--><activity android:name=".AccountSystemActivity"/><!-- 系統管理 --><activity android:name=".AccountAddPassword"/><!-- 增加密碼 --><activity android:name=".AccountFlagActivity"/><!-- 收支便簽 --><activity android:name=".AccountAddMessageActivity"/><!-- 添加便簽 --></application> </manifest>

AccountMainActivity.java 主頁顯示

package com.ds.accountsoft.activity; import com.ds.accountsoft.tools.AccountTools;import android.os.Bundle; import android.util.TypedValue; import android.view.Gravity; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.BaseAdapter; import android.widget.GridView; import android.widget.LinearLayout; import android.widget.LinearLayout.LayoutParams; import android.widget.TextView; import android.app.Activity; import android.content.Context; import android.content.Intent; import android.graphics.drawable.Drawable; public class AccountMainActivity extends Activity {private Context context = AccountMainActivity.this;private GridView gridview;private int [] images ={R.drawable.increase,R.drawable.decrease,R.drawable.easyicon,R.drawable.cance,R.drawable.data,R.drawable.settings,R.drawable.setting,R.drawable.power};private String [] names={"新增支出","新增收入","我的支出","我的收入","數據管理","系統設置","收支便簽","系統退出"};private void bindView(){gridview = (GridView)findViewById(R.id.Grd_arent);BaseAdapter adapter = new BaseAdapter() {@Overridepublic View getView(int position, View arg1, ViewGroup arg2) {LinearLayout layout = new LinearLayout(context);TextView txt = new TextView(context);txt.setText(names[position]);txt.setTextSize(TypedValue.COMPLEX_UNIT_SP,14);LinearLayout.LayoutParams params =new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);txt.setLayoutParams(params);txt.setGravity(Gravity.CENTER);Drawable top = getResources().getDrawable(images[position]);top.setBounds(0, 0, 90,90);txt.setCompoundDrawables(null, top, null, null);layout.addView(txt);return layout;}@Overridepublic long getItemId(int position) {return position;}@Overridepublic Object getItem(int arg0) {return null;}@Overridepublic int getCount() {return names.length;}};gridview.setAdapter(adapter);gridview.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> arg0, View arg1, int which,long arg3) {String text = "進入"+names[which]+"子界面...";switch(which){case 0: Intent out_intent = new Intent(context,AccountAddOutActivity.class);/**新增支出*/startActivity(out_intent);AccountTools.showToast(context, text);break;case 1:Intent in_intent = new Intent(context,AccountAddInActivity.class);/**新增收入*/startActivity(in_intent);AccountTools.showToast(context, text);break;case 2:Intent myout_intent = new Intent(context,AccountMyOutActivity.class);/**我的支出*/startActivity(myout_intent);AccountTools.showToast(context, text);break;case 3: Intent myin_intent = new Intent(context,AccountMyAddActivity.class);/**我的收入*/startActivity(myin_intent);AccountTools.showToast(context, text);break;case 4:Intent manager_intent = new Intent(context,AccountManagerActivity.class);/**數據管理*/startActivity(manager_intent);AccountTools.showToast(context, text);break;case 5: Intent password_intent = new Intent(context,AccountSystemActivity.class);/**系統設置*/startActivity(password_intent);AccountTools.showToast(context, text);break;case 6: Intent flag_intent = new Intent(context,AccountFlagActivity.class);/**收支便簽*/startActivity(flag_intent);AccountTools.showToast(context, text);break;case 7: finish();break;}}});}protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.account_main);bindView();} }

AccountAddOutActivity.java 新增支出

AccountMyAddActivity.java 我的收入

AccountManagerActivity.java 數據管理

AccountFlagActivity.java 收支便簽

還有的頁面也就不放圖了因為都不盡相同

比如新增支出 與 新增收入 、我的支出與我的收入、 還有的
是在數據管理中點擊簡單提示進入 ，

AccountEditOutActivity(修改新增支出)是回顯到像新增支出一樣的頁面來添加修改與刪除事件
AccountEditInActivity(修改新增收入)與它相同

AccountAddPassword 增加密碼事件 未與登錄文本框綁定判斷

系統退出

可執行APK

切記每次修改源碼后執行將需要再次發送安裝來更新
