當我開始我從我的數據庫中呈現結果的活動時，出現此錯誤。我試圖刪除舊數據庫並卸載遊戲，但沒有運氣。這裏是我的OffDBHelper代碼：引起：android.database.sqlite.SQLiteException：沒有這樣的表
public class OffDBHelper {
public static final String KEY_ROWID = "_id";
public static final String KEY_NAME = "name";
public static final String KEY_SCORE = "score";
private static final String DATABASE_NAME = "highscores";
private static final String DATABASE_TABLE = "highscorestable";
public static final int DATABASE_VERSION = 1;
private DbHelper ourHelper;
private final Context ourContext;
private SQLiteDatabase ourDatabase;
private static class DbHelper extends SQLiteOpenHelper{
public DbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" +
KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
KEY_NAME + " TEXT NOT NULL, " +
KEY_SCORE + " INTEGER NOT NULL);"
);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE);
onCreate(db);
}
}
public OffDBHelper(Context c){
ourContext = c;
}
public OffDBHelper open() throws Exception{
ourHelper = new DbHelper(ourContext);
ourDatabase = ourHelper.getWritableDatabase();
return this;
}
public void close(){
ourHelper.close();
}
public long createEntry(String name, double score) {
ContentValues cv = new ContentValues();
cv.put(KEY_NAME, name);
cv.put(KEY_SCORE, score);
return ourDatabase.insert(DATABASE_TABLE, null, cv);
}
public String getData() {
String[] columns = new String[]{KEY_ROWID, KEY_NAME, KEY_SCORE};
Cursor c = ourDatabase.query(DATABASE_NAME, columns, null, null, null, null, null);
String result = "";
int iRow = c.getColumnIndex(KEY_ROWID);
int iName = c.getColumnIndex(KEY_NAME);
int iScore = c.getColumnIndex(KEY_SCORE);
for(c.moveToFirst(); !c.isAfterLast(); c.moveToNext()){
result = result + c.getString(iRow) + " " + c.getString(iName) + " " + c.getString(iScore) + "\n";
}
return result;
}
}
這是我的dialog.theme活動，我插入我的名字：
public class ImePopup extends Activity implements OnClickListener{
EditText ime;
Button ok, odustani;
double score;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.imepopup);
ok = (Button) findViewById(R.id.btOK);
odustani = (Button) findViewById(R.id.btOdustani);
ime = (EditText) findViewById(R.id.etIme);
ok.setOnClickListener(this);
odustani.setOnClickListener(this);
}
public void onClick(View arg0) {
switch (arg0.getId()){
case R.id.btOK:
boolean didItWork = true;
try{
String name = ime.getText().toString();
OffDBHelper entry = new OffDBHelper(ImePopup.this);
entry.open();
entry.createEntry(name, score);
entry.close();
break;
}catch(Exception e){
didItWork = false;
String error = e.toString();
Dialog d = new Dialog(this);
d.setTitle("Greska!");
TextView tv = new TextView(this);
tv.setText("Greska u upisu");
d.setContentView(tv);
d.show();
}finally{
if(didItWork){
Dialog d = new Dialog(this);
d.setTitle("Uspesno!");
TextView tv = new TextView(this);
tv.setText("Upisali ste se!");
d.setContentView(tv);
d.show();
}
}
case R.id.btOdustani:
break;
}
}
}
而且我的活動中，我展示成果：
public class OffRezultati extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.offrezultati);
TextView tvSQLinfo;
TextView tv = (TextView) findViewById(R.id.tvSQLinfo);
OffDBHelper info = new OffDBHelper(this);
try {
info.open();
} catch (Exception e) {
e.printStackTrace();
}
String data = info.getData();
info.close();
tv.setText(data);
}
}
這裏是LogCat：
