android socket發送圖片

傳送圖片，開始信息不全，修改後總算正確傳輸。

java 寫的服務器，把讀取的圖片保存到本地。

public class AndroidRunable implements Runnable {
	Socket socket = null;

	public AndroidRunable(Socket st) {
		this.socket = st;
	}

	public void run() {

		String line = null;
		InputStream input;//讀取客戶端信息
		OutputStream output;//向客戶端發送數據
		String str = "hello android";

		try {
			input = socket.getInputStream();
			BufferedReader bff = new BufferedReader(
					new InputStreamReader(input));
			// 獲取客戶端的信息
			String img = "";
			while ((line = bff.readLine()) != null) {
				img += line;
			}
			String[] imgs = img.split("採集圖片");
			for (int i = 0; i < imgs.length; i++) {
				System.out.println("img>>>" + imgs[i]);
				Decoder d = Base64.getDecoder();
				byte2image(d.decode(imgs[i]), "kk" + i);
			}
			bff.close();
			input.close();
			socket.close();

		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	// byte數組到圖片
	public void byte2image(byte[] data, String path) {
		if (data.length < 3 || path.equals(""))
			return;
		try {
			FileOutputStream imageOutput = new FileOutputStream(new File(
					"C:\\Users\\Administrator\\Desktop\\socket\\" + path
							+ ".png"));
			imageOutput.write(data, 0, data.length);
			imageOutput.close();
			System.out.println("Make Picture success,Please find image in "
					+ path);
		} catch (Exception ex) {
			System.out.println("Exception: " + ex);
			ex.printStackTrace();
		}
	}
}

服務器循環判斷是不是客戶端要建立連接。

public class AndroidService {
	public static void main(String[] args) {
		Socket st = null;
		try {
			ServerSocket socket = new ServerSocket(2584);
			while (true) {
				st = socket.accept();
				new Thread(new AndroidRunable(st)).start();
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			try {
				st.close();
			} catch (IOException e1) {
				// TODO Auto-generated catch block
				e1.printStackTrace();
			}
		}

	}
}

android 客戶端，我讀取的 drawable裏的圖片

  Resources res = getResources();
                Bitmap bmp = BitmapFactory.decodeResource(res, R.drawable.test1);
                String strbm = Base64.encodeToString(BitmapToBytes(bmp), Base64.DEFAULT);
                Bitmap bmp1 = BitmapFactory.decodeResource(res, R.drawable.test2);
                String strbm2 = Base64.encodeToString(BitmapToBytes(bmp1), Base64.DEFAULT);
                Bitmap bt = Bytes2Bimap(Base64.decode(strbm,Base64.DEFAULT));
                System.out.println(strbm + "bt" + bt);
                ImageView iv= (ImageView) findViewById(R.id.img_socket);
                iv.setImageBitmap(bt);
                new SocketThread("採集圖片"+strbm+"採集圖片"+strbm2, MainActivity.this, socket).start();

bitmap轉換爲byte的方法

 public byte[] BitmapToBytes(Bitmap bm) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        bm.compress(Bitmap.CompressFormat.PNG, 100, baos);
        return baos.toByteArray();
    }

  try {
            socket = new Socket();
            //socket.connect(new InetSocketAddress("192.168.1.108", 2584), 5000);
            socket.connect(new InetSocketAddress("192.168.1.105", 2584), 5000);
            //獲取輸入輸出流
            OutputStream ou = socket.getOutputStream();
            //BufferedReader bff = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            //讀取發來服務器信息
            buffer = "";
            //向服務器發送信息
            ou.write((sendMes).getBytes("UTF-8"));
            ou.flush();
            bundle.putString("msg", buffer.toString());
            msg.setData(bundle);
            //發送信息，修改ui線程中的組件
            myHandler.sendMessage(msg);
            // bff.close();
            ou.close();
            socket.close();
        } catch (SocketTimeoutException aa) {
            //連接超時
            bundle.putString("msg", "服務器連接失敗！請檢查網絡是否打開");
            msg.setData(bundle);
            myHandler.sendMessage(msg);
        } catch (IOException e) {
            e.printStackTrace();
        }
