最近 公司的项目上有 扫描二维码功能，当然必不可少的就会有读取本地二维码需求。首先就是跳转到本地相册，如下代码：
/** * show images in the android device media store */ public static void showPictures(Activity a,int type){ Intent innerIntent = new Intent(Intent.ACTION_GET_CONTENT); String IMAGE_UNSPECIFIED = "image/*"; innerIntent.setType(IMAGE_UNSPECIFIED); a.startActivityForResult(innerIntent, type); } 在 onActivityResult中获取图片路径， Uri uri = data.getData(); String strPath = uri.getPath();发现得到的path路径值不是图片在我们手机上的历经，在根据这个路径值获取图片或得到null，不知为啥， 这在大多数手机一般都没问题，但是我用的是红米手机，巨坑的手机之一，之前一直觉得搞开发魅族手机很坑了，原来小米也算其一啊。
然后再onActivityResult做如下处理，结果是二维码，和非二维码图片都可以扫描，并做出相应的处理；
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub super.onActivityResult(requestCode, resultCode, data); Logger.i("test", "---------------------3---------------"); if (data != null) { mProgress = new ProgressDialog(CaptureActivity.this); mProgress.setMessage("已扫描，正在处理..."); mProgress.setCancelable(false); mProgress.show(); final ContentResolver resolver = getContentResolver(); Uri uri = data.getData(); if (requestCode == TypeCodeing.REQUESTCODE_CAPTURE && resultCode == RESULT_OK) { if (!TextUtils.isEmpty(uri.getAuthority())) { Logger.e(this, "url=" + data.getData() + "=resolver=" + resolver); Cursor cursor = resolver.query(uri, new String[]{MediaStore.Images.Media.DATA}, null, null, null); if (cursor != null) { if (cursor.moveToFirst()) { photoPath = cursor.getString(cursor .getColumnIndex(MediaStore.Images.Media.DATA)); cursor.close(); } } else { ToastUtil.show("啥也没扫出来，"); mProgress.dismiss(); return; } }else{ photoPath = uri.getPath(); } new Thread(new Runnable() { @Override public void run() { // TODO Auto-generated method stub Looper.prepare(); String result = parsLocalPic(photoPath); Logger.e(this, "result=" + result + "=photoPath=" + photoPath); if (result != null) { if (handler == null) { handler = new CaptureActivityHandler( CaptureActivity.this); } Message msg = new Message(); msg.obj = result; msg.what = R.id.decode_succeeded; handler.sendMessageDelayed(msg, 1000); } else { if (mProgress != null && mProgress.isShowing()) { mProgress.dismiss(); } ToastUtil.show("啥也没扫出来，要不换张图片试试( •̥́ ˍ •̀ू )"); } Looper.loop(); } }).start(); } } else { Logger.e(this, "data==" + data); ToastUtil.show("empty"); return; } } ok 搞定
