I am having trouble replacing a fragment from the onLoadFinished() method of my
loader. I have posted the problem to StackOverflow here
<http://stackoverflow.com/questions/38685437/listviews-performitemclick-causes-illegalstateexception-when-called-inside-on>.
When I checked the source code for LoaderManager, I found that the following
code sets the variable mNoTransactionsBecause to "onLoadFinished".
I know it's related to Android framework's internal design but can anyone shed
some light on the rationale behind blocking fragment transactions
in this way?
void callOnLoadFinished(Loader<Object> loader, Object data) {
if (mCallbacks != null) {
String lastBecause = null;
if (mActivity != null) {
lastBecause = mActivity.mFragments.mNoTransactionsBecause;
mActivity.mFragments.mNoTransactionsBecause = "onLoadFinished";
}
try {
if (DEBUG) Log.v(TAG, " onLoadFinished in " + loader + ": "
+ loader.dataToString(data));
mCallbacks.onLoadFinished(loader, data);
} finally {
if (mActivity != null) {
mActivity.mFragments.mNoTransactionsBecause = lastBecause;
}
}
mDeliveredData = true;
}
}
