2. package com.example.thinbtclient; import java.io.*;
import java.io.*;
import java.io.FilterOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.io.InputStream;
import java.util.UUID;
import com.android.ViewEvent.R;
import android.app.Activity;
import android.bluetooth.BluetoothAdapter;
import android.bluetooth.BluetoothDevice;
import android.bluetooth.BluetoothSocket;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;
把這些都import進去，因為沒有這些有下面程式碼也不能跑

3. public class ThinBTClient extends Activity {
public static void main(String[] args) throws IOException {
BufferedReader mText = new BufferedReader(newInputStreamReader(System.in)); }
這邊是輸入
double x = 0;
double y = 0; 這兩個都是宣告
/** Called when the activity is first created. */
private TextView mtext;
private LinearLayout myLayout;
private static final String TAG = "THINBTCLIENT";
private static final boolean D = true;
private BluetoothAdapter mBluetoothAdapter = null;
private BluetoothSocket btSocket = null;
private InputStream inStream = null;
private OutputStream outStream = null;
private PrintStream out = null;
private static final UUID MY_UUID = UUID.fromString(" A0-B0C0D0E0F099");
private static String address = "00:15:83:49:42:47";
這些是藍芽的設定

4. public void onCreate(Bundle savedInstanceState) {
@Override
配合繼承架構， 衍生類別的虛擬函式可以取代基礎類別的同名虛擬函式，
運用多型指標時虛擬函式呼叫可以動態地繫結 (bind) 到該物件的虛擬函式上
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mtext = (TextView) this.findViewById(R.id.myText);
myLayout = (LinearLayout) this.findViewById(R.id.myLinear);
myLayout.setOnTouchListener(mTouchListener);

if (D)
Log.e(TAG, "+++ ON CREATE +++");
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
Toast.makeText(this,
"Bluetooth is not available.",
Toast.LENGTH_LONG).show();
finish();
return; }
藍芽沒開

5. if (!mBluetoothAdapter.isEnabled()) {
Toast.makeText(this,
"Please enable your BT and re-run this program.",
Toast.LENGTH_LONG).show();
finish();
return; }
藍芽有開
if (D)
Log.e(TAG, "+++ DONE IN ON CREATE, GOT LOCAL BT ADAPTER +++");
public OnTouchListener mTouchListener = new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event)
PrintStream p = new PrintStream( outStream );
p.print("__X: " + event.getX() + ",__Y: " + event.getY());
mtext.setText("__X: " + event.getX() + ",__Y: " + event.getY());
return true; };
觸控面板控制滑鼠座標

6. @Override
public void onResume() {
super.onResume();
if (D) {
Log.e(TAG, "+ ON RESUME +");
Log.e(TAG, "+ ABOUT TO ATTEMPT CLIENT CONNECT +"); }
BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
try {
btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) {
Log.e(TAG, "ON RESUME: Socket creation failed.", e);
讀取藍芽裝置的編碼

7. mBluetoothAdapter.cancelDiscovery();
try {
btSocket.connect();
Log.e(TAG, "ON RESUME: BT connection established, data transfer link open.");
} catch (IOException e) {
btSocket.close();
} catch (IOException e2) {
Log.e(TAG,"ON RESUME: Unable to close socket during connection failure", e2); }
尋找藍芽發送端的通道

8. Log.e(TAG, “+ ABOUT TO SAY SOMETHING TO SERVER +”);
if (D)
Log.e(TAG, “+ ABOUT TO SAY SOMETHING TO SERVER +”);
try {
outStream = btSocket.getOutputStream();
} catch (IOException e) {
Log.e(TAG, "ON RESUME: Output stream creation failed.", e); }
String message = "Hello message from client to server.";
byte[] msgBuffer = message.getBytes();
outStream.write(msgBuffer);
Log.e(TAG, "ON RESUME: Exception during write.", e);
印出Stream的訊息

9. public void onPause() { super.onPause(); if (D)
@Override
public void onPause() {
super.onPause();
if (D)
Log.e(TAG, "- ON PAUSE -");
if (outStream != null) {
try {
outStream.flush();
} catch (IOException e) {
Log.e(TAG, "ON PAUSE: Couldn't flush output stream.", e); }
try {
btSocket.close();
} catch (IOException e2) {
Log.e(TAG, "ON PAUSE: Unable to close socket.", e2);
關閉藍芽
