1.1 客戶(hù)端簡(jiǎn)介

1.1.1 界面操作

進(jìn)入頁(yè)面后，會(huì)自動(dòng)進(jìn)行掃描，以發(fā)現(xiàn)周?chē)�可用藍(lán)牙設(shè)備。

在搜索藍(lán)牙設(shè)備的多層中，會(huì)出現(xiàn)圓環(huán)形進(jìn)度條，當(dāng)設(shè)定的搜索時(shí)間到了之后，或者我們選中了被掃描到的設(shè)備，該進(jìn)度條消失，“停止掃描”轉(zhuǎn)換會(huì)“掃描”。

點(diǎn)擊掃描到的設(shè)備進(jìn)入控制設(shè)備控制頁(yè)面。

這個(gè)頁(yè)面是我們的主要控制界面，我們可以在這個(gè)界面看到手環(huán)為我們提供的一些數(shù)據(jù)。

這個(gè)下拉菜單可以同過(guò)點(diǎn)擊也可以通過(guò)設(shè)備的menu按鍵獲得，主要用來(lái)控制計(jì)步器。

“斷開(kāi)連接”的按鈕的作用是顯示現(xiàn)在設(shè)備的連接情況，如果不是已經(jīng)連接了設(shè)備，那么可以看到“連接”按鈕，可以通過(guò)“連接”按鈕來(lái)實(shí)現(xiàn)和藍(lán)牙設(shè)備的連接，如果是已經(jīng)連接了的設(shè)備，可以看到“斷開(kāi)連接”，可以通過(guò)“斷開(kāi)連接”來(lái)斷開(kāi)和藍(lán)牙設(shè)備的連接。

設(shè)置時(shí)間按鈕，可以將我們的設(shè)備上的時(shí)間，同步到藍(lán)牙手環(huán)上。

1.1.2 工程結(jié)構(gòu)

Src為java文件目錄。

Res為資源文件目錄。

AndroidManifest.xml為配置文件。

在src目錄下：

Acticity包中，是工程的兩個(gè)Activity活動(dòng)相關(guān)的代碼。

Service包中，是工程啟動(dòng)的服務(wù)相關(guān)代碼。

Tools包中，是工具類(lèi)相關(guān)代碼。

UI包中，是自定義界面相關(guān)代碼。

在資源文件夾中，包含了Layout，values，Drawable等資源文件夾：

其中l(wèi)ayout中是布局文件，menu中，是菜單欄的布局文件，values中包括color，string，styles等設(shè)置。

1.2 代碼分析

1.2.1 界面代碼分析

本工程一共有兩個(gè)主要顯示界面，分別為掃描設(shè)備，和設(shè)備控制，通過(guò)兩個(gè)活動(dòng)—Activity來(lái)進(jìn)行設(shè)置與控制。

掃描-----界面ScanningActivity

在onCreate中設(shè)定標(biāo)題。

Java Code

public void onCreate(Bundle savedInstanceState){

getActionBar().setTitle(R.string.title_devices);

}

在掃描的時(shí)候，menu顯示為“停止掃描”，并顯示圓環(huán)進(jìn)度條以提醒等待;在掃描結(jié)束時(shí)，menu顯示為“掃描”。在界面中使用ListView展示掃描到的設(shè)備。

Java Code

/**

* 創(chuàng)建Menu菜單欄

*/

@Override

public boolean onCreateOptionsMenu(Menu menu)

{

getMenuInflater().inflate(R.menu.main, menu);

if (!mScanning)

{

menu.findItem(R.id.menu_stop).setVisible(false);

menu.findItem(R.id.menu_scan).setVisible(true);

menu.findItem(R.id.menu_refresh).setActionView(null);

} else{

menu.findItem(R.id.menu_stop).setVisible(true);

menu.findItem(R.id.menu_scan).setVisible(false);

menu.findItem(R.id.menu_refresh).setActionView(

R.layout.actionbar_indeterminate_progress);

}

return true;

}

/**

* Menu菜單欄被選擇時(shí)

*/

@Override

public boolean onOptionsItemSelected(MenuItem item)

{

switch (item.getItemId())

{

case R.id.menu_scan:

mLeDeviceListAdapter.clear();

scanLeDevice(true);

break;

case R.id.menu_stop:

scanLeDevice(false);

break;

}

return true;

}

ListView顯示掃描到的設(shè)備。

Java Code

@Override

protected void onResume(){

super.onResume();

if (!mBluetoothAdapter.isEnabled()){

if (!mBluetoothAdapter.isEnabled()){

Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);

}

}

mLeDeviceListAdapter = new LeDeviceListAdapter();

setListAdapter(mLeDeviceListAdapter);

scanLeDevice(true);

}

點(diǎn)擊ListView中的設(shè)備跳轉(zhuǎn)到控制界面。

Java Code

@Override

protected void onListItemClick(ListView l, View v, int position, long id){

final BluetoothDevice device = mLeDeviceListAdapter.getDevice(position);

if (device == null) return;

final Intent intent = new Intent(this, DeviceControlActivity.class);

intent.putExtra(DeviceControlActivity.EXTRAS_DEVICE_NAME, device.getName());

intent.putExtra(DeviceControlActivity.EXTRAS_DEVICE_ADDRESS, device.getAddress());

if (mScanning) {

mBluetoothAdapter.stopLeScan(mLeScanCallback);

mScanning = false;

}

startActivity(intent);

}

設(shè)備控制-------界面DeviceControlActivity

在Activity中設(shè)置主界面：

Java Code

@Override

protected void onCreate(Bundle savedInstanceState){

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_device_control);

initShow();

btnTime.setOnClickListener(this);

final Intent intent = getIntent();

mDeviceName = intent.getStringExtra(EXTRAS_DEVICE_NAME);

mDeviceAddress = intent.getStringExtra(EXTRAS_DEVICE_ADDRESS);

Toast.makeText(this, mDeviceAddress, Toast.LENGTH_SHORT).show();

getActionBar().setTitle(mDeviceName);

getActionBar().setDisplayHomeAsUpEnabled(true);

}

菜單欄包括兩部分，一部分是顯示“連接”或“斷開(kāi)連接”，一部分是隱藏的用以對(duì)計(jì)步功能進(jìn)行設(shè)置。

Java Code

@Override

public boolean onCreateOptionsMenu(Menu menu){

getMenuInflater().inflate(R.menu.device_control, menu);

if (connected) {

menu.findItem(R.id.menu_connect).setVisible(false);

menu.findItem(R.id.menu_disconnect).setVisible(true);

}else{

menu.findItem(R.id.menu_connect).setVisible(true);

menu.findItem(R.id.menu_disconnect).setVisible(false);

}

return true;

}

@Override

public boolean onOptionsItemSelected(MenuItem item){

int id = item.getItemId();

switch (id){

case R.id.setting_gogal:

showGogalDialog();

break;

case R.id.setting_reset:

showResetDialog();

break;

case R.id.setting_stop:

showStopDialog();

break;

case R.id.menu_connect:

mBleService.connect(mDeviceAddress);

return true;

case R.id.menu_disconnect:

mBleService.disconnect();

return true;

case android.R.id.home:

onBackPressed();

return true;

default:

break;

}

return super.onOptionsItemSelected(item);

}

1.2.2 藍(lán)牙連接代碼分析

掃描

藍(lán)牙連接建立的過(guò)程中，首先要先掃描到設(shè)備。

在ScanningActivity中：

Java Code

public class ScanningActivity extends ListActivity{

private LeDeviceListAdapter mLeDeviceListAdapter;

private BluetoothAdapter mBluetoothAdapter;

private boolean mScanning;

private Handler mHandler;

private static final int REQUEST_ENABLE_BT = 1;

// Stops scanning after 10 seconds.

private static final long SCAN_PERIOD = 10000;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

mHandler = new Handler();

//PackageManager.FEATURE_BLUETOOTH_LE

if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)){

Toast.makeText(this, R.string.ble_not_supported, Toast.LENGTH_SHORT).show();

finish();

}

//BluetoothManager

final BluetoothManager bluetoothManager =

(BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);

mBluetoothAdapter = bluetoothManager.getAdapter();

//BluetoothAdapter

if (mBluetoothAdapter == null){

Toast.makeText(this, R.string.error_bluetooth_not_supported, Toast.LENGTH_SHORT).show();

finish();

return;

}

}

private void scanLeDevice(final boolean enable){

if (enable){

mHandler.postDelayed(new Runnable(){

@Override

public void run(){

mScanning = false;

mBluetoothAdapter.stopLeScan(mLeScanCallback);

invalidateOptionsMenu();

}

}, SCAN_PERIOD);

mScanning = true;

mBluetoothAdapter.startLeScan(mLeScanCallback);

}else{

mScanning = false;

mBluetoothAdapter.stopLeScan(mLeScanCallback);

}

invalidateOptionsMenu();

}

private BluetoothAdapter.LeScanCallback mLeScanCallback =

new BluetoothAdapter.LeScanCallback(){

@Override

public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord){

runOnUiThread(new Runnable(){

@Override

public void run(){

mLeDeviceListAdapter.addDevice(device);

mLeDeviceListAdapter.notifyDataSetChanged();

}

});

}

};

}

連接藍(lán)牙

在掃描結(jié)束的時(shí)候，點(diǎn)擊ListView上的設(shè)備名稱(chēng)的時(shí)候，將設(shè)備MAC通過(guò)Intent傳遞給DeviceControlActivity，在控制頁(yè)面啟動(dòng)BLEService服務(wù)，控制設(shè)備連接。

1.2.3 信號(hào)處理

從藍(lán)牙設(shè)備接收數(shù)據(jù)

這里我們使用設(shè)備接收來(lái)自藍(lán)牙的通知即Notification信號(hào)，所以我們需要讓我們的設(shè)備讀取相應(yīng)特征值的可通知信號(hào)。

在BLEService中：

Java Code

public void setCharacteristicNotification(BluetoothGattCharacteristic characteristic, boolean enabled)

{

if (mBluetoothAdapter == null || mBluetoothGatt == null)

{

Log.w(TAG, "BluetoothAdapter not initialized");

return;

}

mBluetoothGatt.setCharacteristicNotification(characteristic, enabled);

if (UUID_FARSIGHT_SMART_WRIST.equals(characteristic.getUuid()))

{

BluetoothGattDescriptor descriptor = characteristic

.getDescriptor(UUID.fromString(GattAttributes.CLIENT_CHARACTERISTIC_CONFIG));

descriptor.setValue(BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE);

mBluetoothGatt.writeDescriptor(descriptor);

}

}

在DeviceControlActivity中，通過(guò)廣播接收器接收來(lái)自BLEService中的廣播發(fā)出的信號(hào)：

Java Code

private final BroadcastReceiver mGattUpdateReceiver = new BroadcastReceiver(){

@Override

public void onReceive(Context context, Intent intent)

{

final String action = intent.getAction();

Log.d(TAG, action);

if (BLEService.ACTION_GATT_CONNECTED.equals(action))

{

connected = true;

invalidateOptionsMenu();

}

else if (BLEService.ACTION_GATT_DISCONNECTED.equals(action))

{

connected = false;

invalidateOptionsMenu();

}

else if (BLEService.ACTION_GATT_SERVICES_DISCOVERED.equals(action))

{

Log.d(TAG, "received Discoveryed");

if (first)

{

first = false;

}

getcharacteristic(mBleService.getSupportedGattServices());

}

else if (BLEService.ACTION_DATA_AVAILABLE.equals(action))

{

String data = intent.getStringExtra(BLEService.EXTRA_DATA);

setTribleAndPower(data);

getcharacteristic(mBleService.getSupportedGattServices());

Log.d("DATAIS", data);

}

}

};

當(dāng)發(fā)現(xiàn)服務(wù)的時(shí)候，調(diào)用getcharacteristic(mBleService.getSupportedGattServices())以判斷特征值是否是我們需要的。

Java Code

private void getcharacteristic(List gattServices){

String uuid = null;

Log.d(TAG, "++++++++++++++++++++++++++++++++++++++++++++");

for (BluetoothGattService gattService : gattServices) {

uuid = gattService.getUuid().toString();

Log.d(TAG, uuid);

if (uuid.equalsIgnoreCase(UUID_date)) {

List gattCharacteristics = gattService.getCharacteristics();

for (BluetoothGattCharacteristic gattCharacteristic : gattCharacteristics)

uuid = gattCharacteristic.getUuid().toString();

Log.d(TAG, uuid + "characteristic");

if (uuid.equalsIgnoreCase(UUID_D)) {

final int charaProp = gattCharacteristic.getProperties();

if ((charaProp | BluetoothGattCharacteristic.PROPERTY_READ) > 0) {

// If there is an active notification on a

// characteristic, clear

if (mNotifyCharacteristic != null) {

mBleService.setCharacteristicNotification(mNotifyCharacteristic, false);

mNotifyCharacteristic = null;

}

mBleService.readCharacteristic(gattCharacteristic);

}

if ((charaProp | BluetoothGattCharacteristic.PROPERTY_NOTIFY) > 0) {

mNotifyCharacteristic = gattCharacteristic;

mBleService.setCharacteristicNotification(gattCharacteristic, true); }

}else{

continue;

}

}

}

}

當(dāng)接收到ACTION_DATA_AVAILABLE廣播的時(shí)候，讀出廣播中的數(shù)據(jù)，并通過(guò)數(shù)據(jù)對(duì)界面進(jìn)行操作。

和接收數(shù)據(jù)時(shí)不一樣的是，我們?cè)诎l(fā)現(xiàn)服務(wù)和特征值之后，就應(yīng)該去查看Phone實(shí)例中是否有未傳輸出去的數(shù)據(jù)，如果有，而且服務(wù)和特征值是我們要發(fā)送的設(shè)備的話(huà)，就要進(jìn)行數(shù)據(jù)傳送。
