首先是拍照:使用Intent即可，
[java] view plaincopyprint?
01.final String start = Environment.getExternalStorageState();
02.private static final String PHOTOPATH = "/photo/";
03.
04.if(start.equals(Environment.MEDIA_MOUNTED)){
05.Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
06.File file = new File(Environment.getExternalStorageDirectory()+PHOTOPATH);
07.if(!file.exists()){
08.file.mkdirs();
09.}
10.tempphontname = System.currentTimeMillis()+".jpg";
11.buffer.append(Environment.getExternalStorageDirectory()+PHOTOPATH).append(tempphontname);
12.intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(buffer.toString())));
13.startActivityForResult(intent, 1);
14.}
final String start = Environment.getExternalStorageState();
private static final String PHOTOPATH = "/photo/";
if(start.equals(Environment.MEDIA_MOUNTED)){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory()+PHOTOPATH);
if(!file.exists()){
file.mkdirs();
}
tempphontname = System.currentTimeMillis()+".jpg";
buffer.append(Environment.getExternalStorageDirectory()+PHOTOPATH).append(tempphontname);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(buffer.toString())));
startActivityForResult(intent, 1);
}
其次是从本地相册选：依旧是Intent.
如下代码：
[java] view plaincopyprint?
01.if(start.equals(Environment.MEDIA_MOUNTED)){
02. Intent getImage = new Intent(Intent.ACTION_GET_CONTENT);
03. getImage.addCategory(Intent.CATEGORY_OPENABLE);
04. getImage.setType("image/jpeg");
05. startActivityForResult(getImage, 0);
06.}
if(start.equals(Environment.MEDIA_MOUNTED)){
Intent getImage = new Intent(Intent.ACTION_GET_CONTENT);
getImage.addCategory(Intent.CATEGORY_OPENABLE);
getImage.setType("image/jpeg");
startActivityForResult(getImage, 0);
}
接下来是主要的：因为调用完系统的方法后，回返回到回调方法onActivityResult(int, int, Intent)中，
在里面进行主要的照片上传服务器的操作，
见代码：
[java] view plaincopyprint?
01.@Override
02. protected void onActivityResult(int requestCode, int resultCode, Intent data) {
03. ContentResolver resolver = getContentResolver();
04. if(requestCode==1)//
05. {
06. if(resultCode==Activity.RESULT_OK)
07. {
08. if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
09. {
10.ew Thread(new Runnable()
11. {
12. @Override
13. public void run() {
14.//进行上传操作
15.}
16.}.start();
