我是android的新手。我有2个表用于存储和显示微调器数据，另一个表用于存储选定的微调器值现在我想以listview的形式显示sqlite数据库表内容，用于android`中的以下代码。
private View.OnClickListener mCorkyListener = new View.OnClickListener() {
public void onClick(View v) {
// do something when the button is clicked
Log.d("button clicked", "button clicked");
String mac_no = my_spinners.getSelectedItem().toString();
String incharge = my_spinnerssss.getSelectedItem().toString();
String operator_name = my_spinnerss.getSelectedItem().toString();
String status_of_mac = my_spinnersss.getSelectedItem().toString();
String fullName = mac_no + " " + status_of_mac;
Log.d("fullname", fullName);
try {
mydb = openOrCreateDatabase(DBNAME, Context.MODE_PRIVATE, null);
// mydb.delete(TABLES, null, null);
mydb.execSQL("CREATE TABLE IF NOT EXISTS " + TABLES
+ " (ID INTEGER PRIMARY KEY, DATE_TIME TEXT, MACHINE_NO INTEGER, OPERATOR_NAME TEXT, STATUS TEXT, INCHARGE TEXT);");
Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String strDate = sdf.format(c.getTime());
Toast.makeText(getApplicationContext(), "The String Date is " + strDate, Toast.LENGTH_LONG).show();
ContentValues data = new ContentValues();
data.put("ID", ID);
data.put("DATE_TIME", strDate);
data.put("MACHINE_NO", mac_no);
data.put("OPERATOR_NAME", operator_name);
data.put("STATUS", status_of_mac);
data.put("INCHARGE", incharge);
if (mydb == null) {
// make sure that your db is properly initialised
}
mydb.insert("RECORD_TABLES", "nullColumnHack", data);
Log.d("Inserted into record table", "Inserted into record table");
mydb.close();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Error in creating table",
Toast.LENGTH_LONG);
}
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) { // Device does not support Bluetooth }
}
Log.d("Bluetooth Adapter is active", "Bluetooth Adapter is active");
try {
if (!mBluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, 1);
Log.d("Intent is enabled", "Intent is enabled");
}
Log.d("Intent is correct", "Intent is correct");
} catch (NullPointerException e) {
}
try {
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) {
for (BluetoothDevice device : pairedDevices) {
BluetoothDevice mDevice = device;
String name = mDevice.getName();
Log.d("mDevice", name);
ConnectThread mConnectThread = new ConnectThread(mDevice, fullName);
mConnectThread.start();
exportDB();
try {
mConnectThread.write(fullName);
} catch (IOException nn) {
}
}
}
} catch (NullPointerException n) {
}
}
};
