此代码将图像保存在“MyApp”中。但是如何在其他活动中加载图像
final EditText txtRegid = (EditText)this.findViewById(R.id.regid);
String RegID = txtRegid.getText().toString();
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File mImageFile = new File(Environment.getExternalStorageDirectory()+File.separator+"MyApp",
"PIC"+RegID+".jpg");
String mSelectedImagePath = mImageFile.getAbsolutePath();
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mImageFile));
startActivityForResult(intent, TAKE_PICTURE);
