今天记录一下如何从，相册和相机获取图片，这个部分也是android 开发中经常用的。获取到相片以后图片的处理就不再这里赘述了，我之前的微博中有详细介绍，大家可以查看。

//启动系统相机Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);startActivityForResult(intent, 1);

//系统相册获取方式Intent intentPick = new Intent(Intent.ACTION_PICK);intentPick.setType("image/*");// 相片类型startActivityForResult(intentPick, 2);

//获取到相片的回调@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {// TODO Auto-generated method stubsuper.onActivityResult(requestCode, resultCode, data);if (resultCode == Activity.RESULT_OK) {if (requestCode == 1) {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imageView.setImageBitmap(bitmap);// 将图片显示在ImageView里} else {Uri selectedImage = data.getData();String[] filePathColumn = { MediaStore.Images.Media.DATA };Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null);cursor.moveToFirst();int columnIndex = cursor.getColumnIndex(filePathColumn[0]);String picturePath = cursor.getString(columnIndex);Log.d("aas", "........." + picturePath);cursor.close();Bitmap bitmap = ImageUtil.getBitmapFromFilePath(picturePath,100, 100);//自己封//装的类imageView.setImageBitmap(bitmap);}}}
