我试图将数据存储到安卓SQLite不创建表。没有这样的表被发现，列名不forund

DBHelper类的SQLite数据库

public class DBHelper extends SQLiteOpenHelper { 

    private static final String TAG = "DBHelper";

      return; 
     }

    public boolean insertRowInVisit(VisitCall visitCall){

     ContentValues contentValues = new ContentValues();

     db.insert(TABLE_VISIT,null,contentValues); 
     return true; 
    }

我试着上的按钮调用点击

DBHelper dbHelper = new DBHelper(CallFormActivity.this); 
dbHelper.insertRowInVisit(visitCall);

卸载都DROP命令及运行 –

设置 - >进入应用程序 - >清除数据和运行应用乌尔提供更好的解决方案 –

你可能会使用一个以前版本的前期数据库，例如，您创建了一个数据库并更改了数据库而不更改版本。 – Abbas

您要删除'TABLE_VISIT'同时创造给每一个可能的解决方案'TABLE_LIVE'。造成这个问题。尝试下面的代码并从createVisitTable()和createLiveTable()

@Override 
public void onCreate(SQLiteDatabase sqLiteDatabase) { 
    Log.d(TAG, "onCreate: Creating dbs"); 
    sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + TABLE_LIVE); 
    sqLiteDatabase.execSQL("DROP TABLE IF EXISTS " + TABLE_VISIT); 

    createVisitTable(sqLiteDatabase); 
    createLiveTable(sqLiteDatabase); 

    Log.d(TAG, "onCreate: db created"); 
}
