将URI路径转化为真实路径
private String getRealPathFromURI(Uri contentURI) {
String result;
Cursor cursor = null;
try {
cursor = getContentResolver().query(contentURI, null, null, null, null);
} catch (Throwable e) {
e.printStackTrace();
}
if (cursor == null) {
result = contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
result = cursor.getString(idx);
cursor.close();
}
return result;
}
