第一步:
<uses-permission

<uses-permission

第二步:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 1);
第三步:

if (resultCode == NewsActivity.RESULT_OK) {
String sdStatus = Environment.getExternalStorageState();

"SD card is not avaiable/writeable right now.");

}

Toast.makeText(this, name, Toast.LENGTH_LONG).show();
Bundle bundle = data.getExtras();
Bitmap bitmap = (Bitmap) bundle.get("data");// 获取相机返回的数据，并转换为Bitmap图片格式
FileOutputStream b = null;
//???????????????????????????????为什么不能直接保存在系统相册位置呢？？？？？？？？？？？？
File file = new File("/sdcard/myImage/");
file.mkdirs();// 创建文件夹
String fileName = "/sdcard/myImage/"+name;
try {

bitmap.compress(Bitmap.CompressFormat.JPEG, 100, b);// 把数据写入文件
} catch (FileNotFoundException e) {

}
