1、按钮触发调用系统相机还是相册，以及是否裁剪
//=================选择照片======start=====================================================================
private String imagePath;
private boolean crop = true;
private boolean isSave = false;
private final int m_width = 400;
private final int m_height = 400;
public void takePhoto() {
// TODO Auto-generated method stub
imagePath = getTakePhotoPath();
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);//"android.media.action.IMAGE_CAPTURE"
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(new File(imagePath)));
if(crop)
{
startActivityForResult(intent,

}else

startActivityForResult(intent,

}
}
public void pickPhoto() {

intent1.setType("image/*");
intent1.setData(MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
if(crop)
{
startActivityForResult(intent1,

null);
cursor.moveToFirst();
String imagePath = cursor.getString(1); // 图片文件路径
}
else if (requestCode == RequestCode.TakePhoto.getCode()
&& resultCode == Activity.RESULT_OK) {
}
else if (requestCode == RequestCode.TakePhoto_crop.getCode()
&& resultCode == Activity.RESULT_OK) {
File file = new File(imagePath);
if(isSave && file.exists())
{
/* Intent intent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri uri = Uri.fromFile(file);
intent.setData(uri);
mContext.sendBroadcast(intent);*/
try {
String picPath = MediaStore.Images.Media.insertImage(mContext.getContentResolver(),
file.getAbsolutePath(), file.getName(), null);
//sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, uuUri));
// mContext.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uuUri));
// mContext.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + Environment.getExternalStorageDirectory())));
uuUri= Uri.parse(picPath);
//mContext.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uuUri));
String[] proj = { MediaStore.Images.Media.DATA };
Cursor actualimagecursor = this.managedQuery(Uri.parse(picPath),proj,null,null,null);
int actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
actualimagecursor.moveToFirst();
String img_path = actualimagecursor.getString(actual_image_column_index);
//Log.d("StorageActivity", "married is " + img_path);

//mContext.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse(file.getAbsolutePath())));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
}
}
Uri uri = Uri.fromFile(new File(imagePath));
imagePath = ConfigManager.getInstance().getTakePhotoPath();
cropImage(uri, m_width, m_width, RequestCode.TakePhoto.getCode(),imagePath);
}
else if (requestCode == RequestCode.PickPhoto_crop.getCode()

}
//截取图片
public void cropImage(Uri uri, int outputX, int outputY, int requestCode,String path){

intent.setDataAndType(uri, "image/*"); //path);//

if(android.os.Build.MANUFACTURER.contains("HUAWEI"))
{//华为特殊处理 不然会显示圆
intent.putExtra("aspectX", 9998);
intent.putExtra("aspectY", 9999);
}
else
{
