嘗試從Android數據庫獲取數據時發生錯誤

我使用SQLite在Android中創建數據庫。我創建了一個從我的數據庫中提取一些數據的類。這是我的類代碼：嘗試從Android數據庫獲取數據時發生錯誤

package com.example.prenotazione_esame; 

import android.database.Cursor; 
import android.database.sqlite.SQLiteDatabase; 

public class GetDataDb { 

    public String [] getAmb(SQLiteDatabase db){ 
     //"SELECT NOME_AMB FROM T_DIZ_AMB"; 
     String [] colonne = {"NOME_AMB"}; 
     Cursor cursor = db.query("T_DIZ_AMB", colonne, null, null, null, null, null); 
     int numero_righe=cursor.getCount(); 

     //inizializzo le variabili necessarie. Con un ciclo for creo un array 
     //di stringhe con i nomi degli ambulatori 
     int k; 
     String [] ambulatorio; 
     ambulatorio = new String[numero_righe]; 
     for(k=0;k<numero_righe+1;k++){ 
      ambulatorio[k]=cursor.getString(k); 
     } 
     return ambulatorio; 
    } 
}

我的數據庫的代碼是：

package com.example.prenotazione_esame; 

import android.app.Activity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 
import android.content.Context; 
import android.database.sqlite.SQLiteDatabase; 
import android.database.sqlite.SQLiteOpenHelper; 

public class LoginDataBase extends SQLiteOpenHelper { 
    private static final String DB_NAME="Login_DB"; 
    private static final int DB_VERSION=1; 

    public LoginDataBase(Context context){ 
     super(context,DB_NAME,null,DB_VERSION); 
    } 
    @Override 
    public void onCreate(SQLiteDatabase db) { 
     String sql=""; 
     sql+= "CREATE TABLE T_LOGIN ("; 
     sql+= " _id_LOGIN INTEGER PRIMARY KEY AUTOINCREMENT,"; 
     sql+= " USERNAME TEXT NOT NULL,"; 
     sql+= " PASSWORD TEXT NOT NULL"; 
     sql+=")"; 
     db.execSQL(sql); 

     String sql2=""; 
     sql2+= "CREATE TABLE T_PROFILO ("; 
     sql2+= " _id_PROFILO INTEGER PRIMARY KEY AUTOINCREMENT,"; 
     sql2+= " NOME TEXT NOT NULL,"; 
     sql2+= " COGNOME TEXT NOT NULL,"; 
     sql2+= " ETA TEXT NOT NULL,"; 
     sql2+= " SESSO TEXT(1) NOT NULL,"; 
     sql2+= " CODICE_FISCALE TEXT NOT NULL,"; 
     sql2+= " CITTA TEXT NOT NULL,"; 
     sql2+= " INDIRIZZO TEXT NOT NULL,"; 
     sql2+= " TELEFONO TEXT NOT NULL,"; 
     sql2+= " _id_L INTEGER UNIQUE NOT NULL,"; 
     sql2+= " FOREIGN KEY(_id_L) REFERENCES T_LOGIN(_id_LOGIN)"; 
     sql2+= ")"; 
     db.execSQL(sql2); 

     String sql3=""; 
     sql3+= "CREATE TABLE T_DIZ_AMB ("; 
     sql3+= " _id_AMB INTEGER PRIMARY KEY AUTOINCREMENT,"; 
     sql3+= " NOME_AMB TEXT NOT NULL,"; 
     sql3+= ")"; 
     db.execSQL(sql3); 

     String sql4=""; 
     sql4+= "CREATE TABLE T_DIZ_PRE ("; 
     sql4+= " _id_PRE INTEGER PRIMARY KEY AUTOINCREMENT,"; 
     sql4+= " NOME_PRE TEXT NOT NULL,"; 
     sql4+= " _id_FK_AMB INTEGER NOT NULL,"; 
     sql4+= " FOREIGN KEY(_id_FK_AMB) REFERENCES T_DIZ_AMB(_id_AMB)"; 
     sql4+= ")"; 
     db.execSQL(sql4); 

     String sql5=""; 
     sql5+="CREATE TABLE T_RIEPILOGO ("; 
     sql5+=" _id_RIEPILOGO INTEGER PRIMARY KEY AUTOINCREMENT,"; 
     sql5+= " DATA DATE NOT NULL,"; 
     sql5+= " ORA TIME NOT NULL,"; 
     sql5+= " _id_FK_L2 INTEGER NOT NULL,"; 
     sql5+= " FOREIGN KEY(_id_FK_L2) REFERENCES T_LOGIN(_id_LOGIN),"; 
     sql5+= " _id_FK_PRE INTEGER NOT NULL,"; 
     sql5+= " FOREIGN KEY(_id_FK_PRE) REFERENCES T_DIZ_PRE(_id_PRE)"; 
     sql5+= ")"; 
     db.execSQL(sql5); 

     //INSERT di dati 
     String sql6=""; 
     sql6+= "INSERT INTO T_DIZ_AMB (_id_AMB,NOME_AMB)"; 
     sql6+= "VALUES (1,'Cardiologia')"; 
     db.execSQL(sql6); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // Aggiornamento delle tabelle 
    } 
}

Eclipse的說，我沒有創建T_DIZ_AMB表。但是看我的數據庫代碼，我說我已經創建了它。這是我的logcat：

如何解決此錯誤？謝謝。

這是我的Prenota.java。正如你可以看到這個文件調用類GetDataDb。

package com.example.prenotazione_esame; 

import android.app.Activity; 
import android.app.AlertDialog; 
import android.content.DialogInterface; 
import android.content.Intent; 
import android.database.sqlite.SQLiteDatabase; 
import android.os.*; 
import android.widget.Button; 
import android.widget.ListView; 
import android.view.View; 
import android.widget.ArrayAdapter; 


public class Prenota extends Activity { 
    private LoginDataBase dbLogin; 
    GetDataDb dbData = new GetDataDb(); 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.prenota); 
     ListView lista = (ListView) findViewById(R.id.listViewAmbulatorio); 
     dbLogin = new LoginDataBase(this); 
     SQLiteDatabase db = dbLogin.getWritableDatabase(); 
     String [] array = dbData.getAmb(db);  
     //String [] array = {"a","b"}; 
     ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
       this,R.layout.row,R.id.textViewList,array 
       ); 
     lista.setAdapter(arrayAdapter); 
     //arrayAdapter.add("A"); 
    } 
}

這是我與外鍵的問題，新的logcat：

This is my new logcat with the problem in the foreign key:

在末尾移動FOREIGN KEY聲明。你不能像_id_FK_PRE INTEGER NOT NULL列定義像FOREIGN KEY表約束之後，作爲syntax diagram描述：

enter image description here

ArrayIndexOutOfBoundsException：這裏的條件是錯誤的：

ambulatorio = new String[numero_righe]; 
for(k=0;k<numero_righe+1;k++){ 
    ambulatorio[k]=cursor.getString(k); 
}

更改爲k<numero_righe例如刪除+1。

將getString(k)更改爲getString(0)，因爲遊標中只有一個列值。

另外考慮將光標移動到一個新的行，使用moveToNext()，除非你想一遍又一遍地重複相同的值。

現在我的數據庫運行良好，但還有另一個問題。我發佈另一個新的logcat。 – Gianluca

呃。這是失控的。請嘗試每個問題只有一個問題。 SO不是您的互動調試服務。暫時回答你的下一個問題。 – laalto

好的。非常感謝你。現在我的應用運行良好。再次感謝你。祝你今天愉快。 – Gianluca

在該行刪除多餘的,

sql3+= " NOME_AMB TEXT NOT NULL,";

，然後重試。

您所查詢的是錯誤的

String sql3=""; 
     sql3+= "CREATE TABLE T_DIZ_AMB ("; 
     sql3+= " _id_AMB INTEGER PRIMARY KEY AUTOINCREMENT,"; 
     sql3+= " NOME_AMB TEXT NOT NULL,"; //comma should not be here 
     sql3+= ")";

從最後一個字段刪除逗號「」和如下更改;

String sql3=""; 
     sql3+= "CREATE TABLE T_DIZ_AMB ("; 
     sql3+= " _id_AMB INTEGER PRIMARY KEY AUTOINCREMENT,"; 
     sql3+= " NOME_AMB TEXT NOT NULL"; 
     sql3+= ")";

編輯：

定義所有FORIENG KEY在你的表中的最後那就是規則。在此SQL聲明

sql5+= " _id_FK_L2 INTEGER NOT NULL,"; 
    sql5+= " _id_FK_PRE INTEGER NOT NULL,"; 
    sql5+= " FOREIGN KEY(_id_FK_L2) REFERENCES T_LOGIN(_id_LOGIN),"; 
    sql5+= " FOREIGN KEY(_id_FK_PRE) REFERENCES T_DIZ_PRE(_id_PRE)"; 
    sql5+= ")";

我刪除逗號，但現在我有新的錯誤。我發佈了它 – Gianluca

@Gianluca從你的錯誤'應用程序可能在其主線程上做了太多工作。「它表明你在主UI線程上做了一些耗時的任務。張貼更多的代碼。 – GrIsHu

我添加了更多的代碼。另一個文件Java。也許這個錯誤在這個類裏面。 – Gianluca

刪除最後一個逗號（，）（NOME_AMB TEXT NOT NULL,）： 如下更改查詢

String sql3=""; 
     sql3+= "CREATE TABLE T_DIZ_AMB ("; 
     sql3+= " _id_AMB INTEGER PRIMARY KEY AUTOINCREMENT,"; 
     sql3+= " NOME_AMB TEXT NOT NULL,"; 
     sql3+= ")"; 
     db.execSQL(sql3);

檢查你的日誌，同時執行這個查詢，你會在執行此得到例外line ...
