标签： android database sqlite insert

我必须开发一个跌倒探测器应用程序，我决定创建一个数据库来保存它的相关信息。但是当应用程序必须写入数据库时​​，logcat上会出现错误。这是logcat错误

这是sqliteopenhelper的代码java 

package it.unipd.dei.rilevatoredicadute; 
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class MyDBHelper extends SQLiteOpenHelper {

private static final int DATABASE_VERSION = 5;
private static final String DATABASE_NAME = "progettoDB.db";
public static final String TABLE_SESSIONE = "Sessione";
public static final String TABLE_CADUTA="Caduta";   

public static final String COL_IDS = "_id";
public static final String COL_NOME = "Nome";
public static final String COL_DATA = "DataInizio";
public static final String COL_ORA="OraInizio";
public static final String COL_DURATA = "Durata";
public static final String COL_NCADUTE = "NCadute";

public static final String COL_IDC="_id";

public static final String COL_LAT = "Latitudine";
public static final String COL_LON = "Longitudine";
public static final String COL_SESS = "NSessione"; 

public MyDBHelper(Context context) {
    super(context, DATABASE_NAME, null, DATABASE_VERSION);
}   
@Override
public void onCreate(SQLiteDatabase db) {
    String CREATE_SESSIONE_TABLE = " CREATE TABLE " +
                TABLE_SESSIONE + "("
                + COL_IDS + " INTEGER PRIMARY KEY, "

                + COL_DURATA + " TEXT NOT NULL, "
                + COL_NCADUTE + " INTEGER NOT NULL" + ");";     
        db.execSQL(CREATE_SESSIONE_TABLE);

    /*String CREATE_CADUTA_TABLE = "CREATE TABLE " +
                TABLE_CADUTA + "("
                + COL_IDC + " INTEGER PRIMARY KEY," + COL_DATAC

        db.execSQL(CREATE_CADUTA_TABLE);*/
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_SESSIONE);
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_CADUTA);
        onCreate(db);
}   

}

这是我管理数据库的代码java（MyDBManager.java）

package it.unipd.dei.rilevatoredicadute;

import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.content.ContentValues;
import android.database.sqlite.SQLiteException;

public class MyDBManager{

private MyDBHelper dbhelper;

public MyDBManager(Context ctx){

    dbhelper=new MyDBHelper(ctx);
    //SQLiteDatabase db = dbhelper.getWritableDatabase();
}

public void close(){

dbhelper.close();   

}


public void addSessione(String nome, String data, String ora, String durata ,int ncadute){

    SQLiteDatabase db = dbhelper.getWritableDatabase();

    ContentValues cv = new ContentValues();
    cv.put(MyDBHelper.COL_NOME, nome);
    cv.put(MyDBHelper.COL_DATA, data);
    cv.put(MyDBHelper.COL_ORA, ora);
    cv.put(MyDBHelper.COL_DURATA, durata);
    cv.put(MyDBHelper.COL_NCADUTE, ncadute);                        

    db.insert(MyDBHelper.TABLE_SESSIONE, null, cv);
}

public void addCaduta(String data, String ora, String lat, String lon, String sessione){

    SQLiteDatabase db = dbhelper.getWritableDatabase();

    ContentValues cv = new ContentValues();
    cv.put(MyDBHelper.COL_DATAC, data);
    cv.put(MyDBHelper.COL_ORAC, ora);
    cv.put(MyDBHelper.COL_LAT, lat);
    cv.put(MyDBHelper.COL_LON, lon);
    cv.put(MyDBHelper.COL_SESS, sessione);

    db.insert(MyDBHelper.TABLE_CADUTA, null, cv);
}

public boolean deleteSessione(int id){
SQLiteDatabase db = dbhelper.getWritableDatabase();
try{
    if(db.delete(MyDBHelper.TABLE_SESSIONE, MyDBHelper.COL_IDS + "=?", new String[]{Integer.toString(id)})> 0)
        return true;
    return false;
}
catch(SQLiteException sqle){
    return false;
}   
}

public boolean renameSessione(String newName, int id)
{
SQLiteDatabase db=dbhelper.getWritableDatabase();
String RENAME_SESSIONE = "UPDATE" + MyDBHelper.TABLE_SESSIONE + "SET"    + MyDBHelper.COL_NOME + "=" 
                        + newName + "WHERE"+ MyDBHelper.COL_IDS + "= ?" + id + "";
db.execSQL(RENAME_SESSIONE);
return true;
}

public Cursor selectSessione(){
Cursor crs=null;
 try
 {
    SQLiteDatabase db=dbhelper.getReadableDatabase();
    crs=db.query(MyDBHelper.TABLE_SESSIONE, null, null, null, null, null, null, null);        
 }
 catch(SQLiteException sqle)
 {
   return null;
   }     
 return crs;
 }

 public Cursor selectCaduta()
 {
 Cursor crs=null;
 try
 {
     SQLiteDatabase db=dbhelper.getReadableDatabase();
     crs=db.query(MyDBHelper.TABLE_CADUTA, null, null, null, null, null, null, null);

 }
 catch(SQLiteException sqle)
 {
     return null;
 }     
 return crs;     
 }

}

这是mainactivity java，我打开db然后关闭它

package it.unipd.dei.rilevatoredicadute;

import java.util.LinkedList;
import java.util.List;
import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.database.Cursor;

public class MainActivity extends ActionBarActivity {   

MyDBManager db= new MyDBManager(this);  

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);           
    ListView listView = (ListView) findViewById(R.id.listView1);
    List<Dati> list = new LinkedList<Dati>();

    Cursor crs=db.selectSessione();         
    if(crs.moveToFirst()){
        String strData =    crs.getString(crs.getColumnIndex("DataInizio"));
        String[] dataf=strData.split("/");
        int day=Integer.parseInt(dataf[0]);  
        int month=Integer.parseInt(dataf[1]);  
        int year=Integer.parseInt(dataf[2]);

        String strTime = crs.getString(crs.getColumnIndex("OraInizio"));
        String[] oraf=strTime.split(":");
        int hour=Integer.parseInt(oraf[0]);  
        int minutes=Integer.parseInt(oraf[1]);  
        int seconds=Integer.parseInt(oraf[2]); 
        do{
            list.add(new Dati(crs.getString(0),day, month, year,hour, minutes, seconds));
        }while(crs.moveToNext());//fine while
    }
    else{
        list.add(new Dati());
    }
    crs.close();

    CustomAdapter adapter = new CustomAdapter(this, R.layout.list_items, list);
    listView.setAdapter(adapter);
    listView.setOnItemClickListener(new OnItemClickListener(){
    public void onItemClick(AdapterView<?> adapter, View v, int position, long id){
        //Dati value = (Dati)adapter.getItemAtPosition(position);
        Intent UI2 = new Intent(getApplicationContext(), Second.class);
        startActivity(UI2);
        }
    });        
    //db.close();

}
@Override
protected void onDestroy() 
{
    super.onDestroy();
    if (db != null) 
    {
        db.close();
    }
}


@Override
public boolean onCreateOptionsMenu(Menu menu){
    super.onCreateOptionsMenu(menu);
    MenuItem meIt1 = menu.add(0, R.id.nuovaSessione, 1, "Nuova Sessione");
    MenuItem meIt2 = menu.add(0, R.id.delete, 2, "Elimina");
    MenuItem meIt3 = menu.add(0, R.id.rinomina, 3, "Rinomina");
    MenuItem meIt4 = menu.add(0, R.id.preferenze, 4, "Preferenze");
    meIt1.setIntent(new Intent(this, Third.class));
    meIt4.setIntent(new Intent(this, Fifth.class));
    meIt3.setIntent(new Intent(this, Sixth.class));
    return true;
} 

}

至少这是我在数据库中插入raw的代码java（Third.java）

package it.unipd.dei.rilevatoredicadute;

import android.os.Bundle;
import android.view.Menu;

import android.widget.ImageButton;
import android.widget.TextView;
import android.content.Context;
import android.content.Intent;
import java.util.GregorianCalendar;

public class Third extends ActionBarActivity {

Dati da = new Dati();
GregorianCalendar cal = new GregorianCalendar();


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_third);


    final EditText et = (EditText)findViewById(R.id.insTesto);      

    final ImageButton playBtn = (ImageButton)findViewById(R.id.start);
    final ImageButton pauseBtn = (ImageButton)findViewById(R.id.pause);
    final ImageButton stopBtn = (ImageButton)findViewById(R.id.stop);
    pauseBtn.setVisibility(View.INVISIBLE);
    playBtn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            //boolean play=true;
            //if(play){
            playBtn.setVisibility(View.INVISIBLE);
            pauseBtn.setVisibility(View.VISIBLE);   

            da.setData(cal.get(GregorianCalendar.YEAR), cal.get(GregorianCalendar.MONTH)+1, cal.get(GregorianCalendar.DATE));
            String data = da.getData();

            da.setHour(cal.get(GregorianCalendar.HOUR_OF_DAY), cal.get(GregorianCalendar.MINUTE), cal.get(GregorianCalendar.SECOND));
            String ora = da.getHour();

            MyDBManager db = new MyDBManager(getApplicationContext());
            db.addSessione(et.getText().toString(), data, ora, "0:0:0", 0);
            db.close();
            /*play=false;
            }
            else{
                playBtn.setVisibility(View.VISIBLE);
                pauseBtn.setVisibility(View.INVISIBLE);
            }*/
             }          
    });
}

/*@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.third, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}*/
}

我遵循建议更改数据库版本和unistalling并重新安装设备上的应用程序（archos），但logcat给了我同样的问题。有人可以帮帮我吗？ PS抱歉我的英文非常糟糕

1 个答案:

答案 0 :(得分：1)

表格是第一次使用时创建的。如果添加另一个表，则无法创建此表，因为oncreate methot会在第一次使用时创建表。 uprage db version并使用onUprage覆盖方法删除表并调用oncreate方法
