Как просмотреть полную базу данных, которую я создал в android. Программа базы данных является следующим образом-как просмотреть полную базу данных в android?
public class DatabaseHelper extends SQLiteOpenHelper
{
public static final String TABLE_NAME = "scorecard";
public static final String COLUMN_1 ="hole_score1";
public static final String COLUMN_2 ="hole_score2";
public static final String COLUMN_3 ="hole_score3";
public static final String COLUMN_4 ="hole_score4";
public static final String COLUMN_5 ="hole_score5";
public static final String COLUMN_6 ="hole_score6";
public static final String COLUMN_7 ="hole_score7";
public static final String COLUMN_8 ="hole_score8";
public static final String COLUMN_9 ="hole_score9";
public static final String COLUMN_10 ="hole_score10";
public static final String COLUMN_11 ="hole_score11";
public static final String COLUMN_12 ="hole_score12";
public static final String COLUMN_13 ="hole_score13";
public static final String COLUMN_14 ="hole_score14";
public static final String COLUMN_15 ="hole_score15";
public static final String COLUMN_16 ="hole_score16";
public static final String COLUMN_17 ="hole_score17";
public static final String COLUMN_18 ="hole_score18";
public static final String DATABASE_NAME = "scorecard.db";
public static final int DATABASE_VERSION = 1;
//create database
public static final String DATABASE_CREATE = "create table " + TABLE_NAME + " (" + BaseColumns._ID + " integer primary key autoincrement, " + COLUMN_1 + " integer, " + COLUMN_2 + " integer, " + COLUMN_3 +" integer, "+ COLUMN_4 +" integer, "+ COLUMN_5 +" integer, "+ COLUMN_6 +" integer, "+ COLUMN_7 +" integer, "+ COLUMN_8 + " integer, "+COLUMN_9 +" integer, "+ COLUMN_10 +" integer, "+ COLUMN_11 +" integer, "+ COLUMN_12 +" integer, "+ COLUMN_13 +" integer, "+ COLUMN_14 +" integer, "+ COLUMN_15 +" integer, "+ COLUMN_16 +" integer, "+ COLUMN_17 +" integer, "+ COLUMN_18 + " integer);";
public DatabaseHelper(Context context)
{
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db)
{
// TODO Auto-generated method stub
Log.v("nikhil","Creating a database");
db.execSQL(DATABASE_CREATE);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
// TODO Auto-generated method stub
Log.w(DatabaseHelper.class.getName(),
"Upgrading database from version " + oldVersion + " to "
+ newVersion + ", which will destroy all old data");
db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME);
onCreate(db);
}
}
А для просмотра базы данных в настоящее время это код у меня есть, но только одно поле из базы данных показывает вверх.
public class statistics extends Activity {
private DatabaseHelper dataHelper;
SQLiteDatabase db;
String columns[] = {"hole_score1" ,"hole_score2" ,"hole_score3" ,"hole_score4" ,"hole_score5" ,"hole_score6" ,"hole_score7" ,"hole_score8" ,"hole_score9" ,"hole_score10" ,"hole_score11" ,"hole_score12" ,"hole_score13" ,"hole_score14" ,"hole_score15" ,"hole_score16" ,"hole_score17" , "hole_score18"};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.statistics);
TextView tv;
tv = (TextView)this.findViewById(R.id.textView1);
dataHelper = new DatabaseHelper(this);
db = dataHelper.getReadableDatabase();
String data = data();
tv.setText(data);
}
public String data(){
Cursor c;
String result;
c = db.query("scorecard",columns,null,null,null,null,null);
if (c.moveToFirst()){
for(int i=0;i<18;i++){
result = c.getString(i);
return result;
}
}
}
}
Что вы хотите на самом деле? Собираетесь ли вы отображать данные таблицы Sqlite или вы говорите о инструментах просмотра базы данных Sqlite? –
