下面是我的代码但是没有给我onActivity结果中的图像路径
- Uri selectedImageUri = data.getData();
- selectedImagePath = getPath(selectedImageUri);
- Log.w("jay","Camera Image Path :" + selectedImagePath);
- Toast.makeText(MiscansOther_pannel.this,selectedImagePath,Toast.LENGTH_LONG).show();
解决方法
这对我有用……
码：
- Uri selectedImageUri = data.getData();
- selectedImagePath = getRealPathFromURI(selectedImageUri);
方法：getRealPathFromURI()
- //----------------------------------------
- /**
- * This method is used to get real path of file from from uri
- *
- * @param contentUri
- * @return String
- */
- //----------------------------------------
- public String getRealPathFromURI(Uri contentUri)
- {
- try
- {
- String[] proj = {MediaStore.Images.Media.DATA};
- Cursor cursor = managedQuery(contentUri,proj,null,null);
- int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
- cursor.moveToFirst();
- return cursor.getString(column_index);
- }
- catch (Exception e)
- {
- return contentUri.getPath();
- }
- }
编辑：
正如我在一些设备中注意到捕获的图像后,onActivityResult()中的数据为空,
因此,替代方法是将特定图像文件名作为参数传递给您的Intent,以捕获图像作为putExtra参数.
然后还将此图像Uri插入Media Store,现在使用此Uri进一步使用,
您可以通过File.exist()检查图像是否被捕获,
代码看起来像,
- ContentValues values = new ContentValues();
- values.put(MediaStore.Images.Media.TITLE,"Image File name");
- Uri mCapturedImageURI = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,values);
- Intent intentPicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
- intentPicture.putExtra(MediaStore.EXTRA_OUTPUT,mCapturedImageURI);
- startActivityForResult(intentPicture,ACTION_TAKE_PICTURE);
在这种情况下,它将在onActivityResult()中,
- selectedImagePath = getRealPathFromURI(mCapturedImageURI); // don't use data.getData() as it return null in some device instead use mCapturedImageUR uri variable statically in your code,
