Android(安卓)表单模拟，文件上传！

收藏两端代码，以后直接用！

FormFile.java表单文件对象，用于初始化一个文件。

public class FormFile {/* 上传文件的数据 */    private byte[] data;    private InputStream inStream;    private File file;    /* 文件名称 */    private String filname;    /* 请求参数名称*/    private String parameterName;    /* 内容类型 */    private String contentType = "application/octet-stream";        public FormFile(String filname, byte[] data, String parameterName, String contentType) {        this.data = data;        this.filname = filname;        this.parameterName = parameterName;        if(contentType!=null) this.contentType = contentType;    }        public FormFile(String filname, File file, String parameterName, String contentType) {        this.filname = filname;        this.parameterName = parameterName;        this.file = file;        try {            this.inStream = new FileInputStream(file);        } catch (FileNotFoundException e) {            e.printStackTrace();        }        if(contentType!=null) this.contentType = contentType;    }        public File getFile() {        return file;    }    public InputStream getInStream() {        return inStream;    }    public byte[] getData() {        return data;    }    public String getFilname() {        return filname;    }    public void setFilname(String filname) {        this.filname = filname;    }    public String getParameterName() {        return parameterName;    }    public void setParameterName(String parameterName) {        this.parameterName = parameterName;    }    public String getContentType() {        return contentType;    }    public void setContentType(String contentType) {        this.contentType = contentType;    }    }

SocketHttpRequester.java发送表单数据到服务器

然后在MainActivity.java中直接初始化调用即可：

public class MainActivity extends Activity {    private SurfaceView mSurfaceView = null;    private SurfaceHolder mSurfaceHolder = null;    private Camera mCamera;    private Handler handler;        private int whichPicture = 0;        static Upload upload = null;        /** Called when the activity is first created. */    @SuppressLint("NewApi")@SuppressWarnings("deprecation")@Override    public void onCreate(Bundle savedInstanceState)     {            super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                //        StrictMode.enableDefaults();                StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()  //此处是申明，http://blog.csdn.net/gopain/article/details/17058817 有讲解        .detectDiskReads()          .detectDiskWrites()          .detectNetwork()   // or .detectAll() for all detectable problems          .penaltyLog()          .build());                          mSurfaceView = (SurfaceView)this.findViewById(R.id.surfaceview);        mSurfaceHolder = mSurfaceView.getHolder();        mSurfaceHolder.addCallback(new SurfaceHolderCallback());        Button button = (Button) findViewById(R.id.cameraButton);        Button upload = (Button) findViewById(R.id.uploadButton);        upload.setOnClickListener(upload());        button.setOnClickListener(tackpic());        mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);                   handler=new Handler();        handler.post(runnable);//        new Thread(runnable).start();//直接启用线程也可以，在runnable中相应修改            }        private OnClickListener upload() {return new OnClickListener() {@Overridepublic void onClick(View v) {if(upload == null)upload  =  new Upload(getApplicationContext());        String name=Environment.getExternalStorageDirectory()+"/CameraOn/2.jpg";//文件地址upload.upload(name);}};}Runnable runnable = new Runnable() {        public void run() {//        handler.postDelayed(runnable, 10*1000);        if(upload == null)upload  =  new Upload(getApplicationContext());//        while (true) {//try {//Thread.sleep(10*1000);String name=Environment.getExternalStorageDirectory()+"/CameraOn/2.jpg";upload.upload(name);//} catch (InterruptedException e) {//e.printStackTrace();//}//}            handler.postDelayed(runnable, 50*1000);        }    };
