android 调用相机 相册 及图片上传

拍照

view source print ?

01

// 启动相机

02	startCamera.setOnClickListener( new OnClickListener() {

03

04

@Override

05	public void onClick(View v) {

06	// TODO Auto-generated method stub

07

08	// mCurrentPhotoFile = new File(PHOTO_DIR,getPhotoFileName());

09	// //用当前时间给取得的图片命名

10	Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

11	intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1 );

12	// Intent intent = new

13	// Intent("android.media.action.IMAGE_CAPTURE");

14	// Uri fromFile = Uri.fromFile(mCurrentPhotoFile);

15	// String string = fromFile.toString();

16	// Log.i("gp", string);

17	// intent.putExtra(MediaStore.EXTRA_OUTPUT,

18	// Uri.fromFile(mCurrentPhotoFile));

19	startActivityForResult(intent, CAPTURE_CODE);

20

21

}

22

});

调用系统相册

view source print ?

01

// 查看相片

02	camera_look_photo.setOnClickListener( new OnClickListener() {

03

04

@Override

05	public void onClick(View v) {

06	// TODO Auto-generated method stub

07	Intent intent = new Intent(Intent.ACTION_GET_CONTENT);

08	intent.setType( "image/*" );

09	startActivityForResult(intent, IMAGE_CODE);

10

11

}

12

});

对回调函数进行处理

view source print ?

001	protected void onActivityResult( int requestCode, int resultCode, Intent data) {

002	// TODO Auto-generated method stub

003	super .onActivityResult(requestCode, resultCode, data);

004	ContentResolver resolver = getContentResolver();

005

006

// 拍照

007	if (resultCode != RESULT_OK)

008

return ;

009	switch (requestCode) {

010	case CAPTURE_CODE: {

011	// Toast.makeText(Camera.this, "--------------", 2).show();

016	// doCropPhoto(mCurrentPhotoFile);

图片的上传，以前是用特定的协议进行上传，不知道是协议的什么地方出现了，一直上传不成功。在网上找到另一种上传方法，Http有自己封装好的方法，

view source print ?

01	private void uploadFile2Svr2() {

02	if (paizhao) {

03	file = new File(camera_paht);

04	// paizao图片的地址

05

}

06	if (xiangce) {

07	if (uploadPhotPath== null )

08

return ;

09	file = new File(uploadPhotPath);

10

}

11

12	System.out.println( "camera------------------------807" );

13	// 相册图片的地址

14

15	String httpUrl = path;

16	System.out.println( "---------------" );

17	HttpPost request = new HttpPost(httpUrl);

18	HttpClient httpClient = new DefaultHttpClient();

19	FileEntity entity = new FileEntity(file, "binary/octet-stream" );

20	HttpResponse response;

21	request.setEntity(entity);

22	entity.setContentEncoding( "binary/octet-stream" );

23

try {

24	response = httpClient.execute(request);

25	System.out.println(response.toString());

26	} catch (ClientProtocolException e) {

27	Toast.makeText(Camera. this , "图片不可用，请重新拍摄上传" , 3 ).show();

28	// TODO Auto-generated catch block

29	e.printStackTrace();

30	} catch (IOException e) {

31	// TODO Auto-generated catch block

32	Toast.makeText(Camera. this , "图片不可用，请重新拍摄上传" , 3 ).show();

33	e.printStackTrace();
