1、
public static final String DATABASE_FILENAME = "stock.db"; // 这个是DB文件名字 public static final String PACKAGE_NAME = "com.huaxa.it.tuling"; // 这个是自己项目包路径 public static final String DATABASE_PATH = android.os.Environment.getExternalStorageDirectory().getAbsolutePath()+"/" +PACKAGE_NAME; // 获取存储位置地址2、将res/raw的db文件读取出来，然后在手机某个目录下并生成db文件
private SQLiteOpenHelper sqlHelper; private static SQLiteDatabase database; private String name = ""; // 股票搜索出来的代码 static String databaseFilename = DATABASE_PATH + "/" + DATABASE_FILENAME; public static SQLiteDatabase openDatabase(Context context) { try { // String databaseFilename = DATABASE_PATH + "/" + DATABASE_FILENAME; File dir = new File(DATABASE_PATH); if (!dir.exists()) { dir.mkdir();//新建文件 } if (!(new File(databaseFilename)).exists()) { InputStream is = context.getResources().openRawResource( R.raw.stock); FileOutputStream fos = new FileOutputStream(databaseFilename); byte[] buffer = new byte[8192]; int count = 0; while ((count = is.read(buffer)) > 0) { fos.write(buffer, 0, count); } fos.close(); is.close(); } database = SQLiteDatabase.openOrCreateDatabase(databaseFilename, null); return database; } catch (Exception e) { e.printStackTrace(); } return null; }3、操作数据库// 获取股票代码 public void getGuPiaoDaiMA(String str) { SQLiteDatabase db = openDatabase(this); Cursor c = db.rawQuery("select * from db where name=?" ,new String[]{"南方航空"});//此处的db是表名，name是列名 c.moveToFirst(); while (!c.isAfterLast()) { name = c.getString(c.getColumnIndex("代码")); c.moveToNext(); } }
