Question

我有一个代码，应该在收到短信时导入数据库。我的问题是我不知道如何在广播接收器类中调用数据库方法我想打电话给这样的话： SELECT * FROM company WHERE sn=1

我得到它像评论！我知道这对于一些人来说是愚蠢和简单的但我刚接触java，我正在使用android studio 2.0

DatabaseHelper.java：

WHERE

IncomingSMSReceiver.java

TouliosDB.eisagoghfititi(temaxismeno_sms[1],temaxismeno_sms[2],temaxismeno_sms[3],temaxismeno_sms[4]);

sms_server.java

package toulios.ptixiakh.toulios;

import android.content.ContentValues;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

public class DatabaseHelper extends SQLiteOpenHelper {

public static final String DATABASE_NAME="Toulios.db";
public static final String TABLE_NAME="Foitites_table";
public static final String Col_AM="AM";
public static final String Col_ONOMA="ONOMA";
public static final String Col_EPITHETO="EPITHETO";
public static final String Col_EXAMINO="EXAMINO";

public DatabaseHelper(Context context) {
    super(context, DATABASE_NAME, null, 1);
   // SQLiteDatabase db=this.getWritableDatabase();
}

@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL("create table " + TABLE_NAME+"(AM INTEGER PRIMARY KEY,ONOMA TEXT,EPITHETO TEXT, EXAMINO INTEGER)");
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS"+TABLE_NAME);
    onCreate(db);
}
public boolean eisagoghfititi(String am,String onoma,String epitheto,String examino)
{
    SQLiteDatabase db=this.getWritableDatabase();
    ContentValues contentValues = new ContentValues();
    contentValues.put(Col_AM,am);
    contentValues.put(Col_ONOMA,onoma);
    contentValues.put(Col_EPITHETO,epitheto);
    contentValues.put(Col_EXAMINO,examino);
    long result = db.insert(TABLE_NAME,null,contentValues);
    if(result == -1)
        return false;
    else
        return true;
}
}

我真的不明白你的问题。只需从您的DatabaseHelper类中调用您的方法即可。替换TouliosDB.eisagoghfititi(temaxismeno_sms[1],temaxismeno_sms[2],temaxismeno_sms[3],temaxismeno_sms[4]);

带

DatabseHelper dbHelper = new DatabaseHelper(context.getApplicationContext());

dbHelper.eisagoghfititi(temaxismeno_sms[1],temaxismeno_sms[2],temaxismeno_sms[3],temaxismeno_sms[4]);
