当我开始展示数据库结果的活动时，我收到此错误。我曾尝试删除旧数据库并卸载游戏，但没有运气。这是我的 OffDBHelper 代码：

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;


    }
}

这是我的 dialog.theme 活动，我在其中插入了我的名字：

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;
}
    }
}

以及我展示结果的活动：

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);



    }

}

这是 LogCat：

改变这一行：

Cursor c = ourDatabase.query(DATABASE_NAME, columns, null, null, null, null, null);

对此

Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, null, null);

表名是：highscorestable而不是highscores在这里你应该有

Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, null, null);

在getData()函数中，替换DATABASE_NAME为DATABASE_TABLE!

    Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, null, null);

你得到了这些 android/sqlite 异常

SQLiteException: no such table: highscores: , while compiling: SELECT _id, imeosobe, skor FROM highscores

android.database.sqlite.SQLiteException: table highscorestable has no column named score: , while compiling: INSERT INTO highscorestable(score, name) VALUES(?, ?);

我会仔细检查你的表和列定义以及你是如何构建插入语句的
