Question

刚开始使用android并尝试创建简单的数据库。

这是我的代码：

HealthyDbHanbler.java

public class HealthyDbHandler extends SQLiteOpenHelper {

public HealthyDbHandler(Context context){
    super(context,FoodMacrosTable.DB_NAME,null,FoodMacrosTable.DB_VERSION);
}

@Override
public void onCreate(SQLiteDatabase sqLiteDatabase) {
    String createTable = "CREATE TABLE " + FoodMacrosTable.FoodMacros.TABLE_NAME + " ( " +
            FoodMacrosTable.FoodMacros._ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
            FoodMacrosTable.FoodMacros.FOOD_NAME + " TEXT NOT NULL, " +
            FoodMacrosTable.FoodMacros.FOOD_PROTEIN + " TEXT NOT NULL, " +
            FoodMacrosTable.FoodMacros.FOOD_CARBS + " TEXT NOT NULL, " +
            FoodMacrosTable.FoodMacros.FOOD_FATS + " TEXT NOT NULL, " +
            FoodMacrosTable.FoodMacros.FOOD_CALORIES + " TEXT NOT NULL, " +
            FoodMacrosTable.FoodMacros.FOOD_VIT_A + " TEXT NOT NULL );";

    sqLiteDatabase.execSQL(createTable);


}

@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {
    sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + FoodMacrosTable.FoodMacros.TABLE_NAME);
    onCreate(sqLiteDatabase);
}

public void addFood(Food food){
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values =  new ContentValues();
    values.put(FoodMacrosTable.FoodMacros.FOOD_NAME,food.getFOOD_NAME());
    values.put(FoodMacrosTable.FoodMacros.FOOD_PROTEIN,food.getFOOD_PROTEIN());
    values.put(FoodMacrosTable.FoodMacros.FOOD_CARBS,food.getFOOD_CARBS());
    values.put(FoodMacrosTable.FoodMacros.FOOD_FATS,food.getFOOD_FATS());
    values.put(FoodMacrosTable.FoodMacros.FOOD_CALORIES,food.getFOOD_CALORIES());
    values.put(FoodMacrosTable.FoodMacros.FOOD_VIT_A,food.getFOOD_VIT_A());

    db.insert(FoodMacrosTable.FoodMacros.TABLE_NAME,null,values);

    db.close();
}

}

MainActivity.java
public class MainActivity extends AppCompatActivity {

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

    HealthyDbHandler db = new HealthyDbHandler(this) ;
    Log.v("DBINFO","Database created");

}

}

这是我得到的错误： 1:42:56 PM无法绑定到本地8600调试器 1:42:56 PM已建立的连接被主机中的软件中止 java.io.IOException：已建立的连接已被主机中的软件中止 at sun.nio.ch.SocketDispatcher.write0（Native Method） at sun.nio.ch.SocketDispatcher.write（SocketDispatcher.java:51）在sun.nio.ch.IOUtil.writeFromNativeBuffer（IOUtil.java:93） at sun.nio.ch.IOUtil.write（IOUtil.java:65） at sun.nio.ch.SocketChannelImpl.write（SocketChannelImpl.java:471）在com.android.ddmlib.JdwpPacket.write（JdwpPacket.java:179）在com.android.ddmlib.Client.send（Client.java:654）在com.android.ddmlib.jdwp.JdwpAgent.send（JdwpAgent.java:92）在com.android.ddmlib.HandleHeap.sendREAQ（HandleHeap.java:349）在com.android.ddmlib.Client.requestAllocationStatus（Client.java:517）在com.android.ddmlib.DeviceMonitor.createClient（DeviceMonitor.java:573）在com.android.ddmlib.DeviceMonitor.openClient（DeviceMonitor.java:545）在com.android.ddmlib.DeviceMonitor.processIncomingJdwpData（DeviceMoni ...（显示气球）

此错误与sqlite甚至您的应用程序无关。

尝试重新启动Android Studio，adb服务器，在您的设备中重新启用USB调试，或从相关主题中重新启动（如果没有任何帮助） Eclipse DDMS error "Can't bind to local 8600 for debugger"

创建数据库不适用于Android / Android Studio
