It seems that whenever you use header/footer views in a listview, your ListView gets wrapped with a HeaderViewListAdapter. You can fix this using the below code: ((YourAdapter)((HeaderViewListAdapter)lv.getAdapter()).getWrappedAdapter()).notifyDataSetChanged();
Yes. Just pass the context of the activity to the adapter in the adapter’s constructor (here stored as mContext). In getView, just call ((Activity) mContext).startActivityForResult(intent,REQUEST_FOR_ACTIVITY_CODE);
I have same problem and have found the answer. You dont use application context, instead, just use getActivity() (if you are in fragment) or this (if you are in activity), it will work dateAdapter = new ArrayAdapter<String>(**this**, android.R.layout.simple_spinner_item, list);
As the Android Developer docs say Even if your app doesn’t use accounts, you still need to provide an authenticator component. If you don’t use accounts or server login, the information handled by the authenticator is ignored, so you can provide an authenticator component that contains stub method implementations. You also need to provide a … Read more
For others who have this problem and have inflated a layout in ArrayAdapter‘s getView, set the parent parameter to null, as in view = inflater.inflate(R.layout.mylayout, null);
CursorAdapter has an implementation of getView() that delegates to newView() and bindView(), in such a way as enforces the row recycling pattern. Hence, you do not need to do anything special with a CursorAdapter for row recycling if you are overriding newView() and bindView().
To be clear, Tano’s solution is sufficient to answer this question. But, in case others run into the same use case I did, here’s some more background that may potentially help you… I had been running into this issue specifically while trying to make a non-editable Material Exposed Dropdown Menu and set it’s initial value … Read more
A container is a specific data structure that contains data, usually in an unbounded amount. Each container type has limitations on how to access, add, or remove data efficiently. Below are a few examples of containers using STL classes. Sequence Containers Here are the sequence containers, meaning the data is reliably ordered (that is, there … Read more
You need to do a few things: 1) In your activity, register for a text change listener on your EditText that contains the value the user enters: mSearchValue.addTextChangedListener(searchTextWatcher); 2) Create your searchTextWatcher and have it do something: private TextWatcher searchTextWatcher = new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) … Read more
This works great for me: public void clear() { int size = data.size(); if (size > 0) { for (int i = 0; i < size; i++) { data.remove(0); } notifyItemRangeRemoved(0, size); } } Source: https://github.com/mikepenz/LollipopShowcase/blob/master/app/src/main/java/com/mikepenz/lollipopshowcase/adapter/ApplicationAdapter.java or: public void clear() { int size = data.size(); data.clear(); notifyItemRangeRemoved(0, size); } For you: @Override protected void onRestart() … Read more
