ListView appears under the clicked button - android

I have the following implementation which runs with no hassle. When user clicks on a button then list view shows. However, list view shows up in the middle of screen. I want it to show up just beneath of the clicked button. Here is my implementation:
MainActivity
namespace DialogExample
{
[Activity (Label = "DialogExample", MainLauncher = true, Icon = "#drawable/icon")]
public class MainActivity : Activity
{
private Button mClickBtn;
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
mClickBtn = FindViewById<Button> (Resource.Id.myButton);
mClickBtn.Click += MClickBtn_Click;
}
void MClickBtn_Click (object sender, EventArgs e)
{
FragmentTransaction transaction = FragmentManager.BeginTransaction ();
Dialog_Form dialogList = new Dialog_Form ();
dialogList.Show (transaction, "Dialog fragment");
}
}
}
Diaolog_Form
namespace DialogExample
{
public class Dialog_Form:DialogFragment
{
private ListView myListView;
private List<string> myList=new List<string> ();
public Dialog_Form ()
{
}
public override View OnCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
base.OnCreateView (inflater, container, savedInstanceState);
myList.Add ("Jason");
myList.Add ("Kenny");
myList.Add ("Tedd");
var view = inflater.Inflate (Resource.Layout.dialog_form, container, false);
myListView = view.FindViewById<ListView> (Resource.Id.myListView);
ArrayAdapter adapter = new ArrayAdapter (Activity, Android.Resource.Layout.SimpleListItem1, myList);
myListView.Adapter = adapter;
return view;
}
public override void OnActivityCreated (Bundle savedInstanceState)
{
Dialog.Window.RequestFeature (WindowFeatures.NoTitle);
base.OnActivityCreated (savedInstanceState);
}
}
}
Main.axml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:id="#+id/myButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Click Here" />
</LinearLayout>
dialog_form.axml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px">
<ListView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:id="#+id/myListView" />
<Button
android:text="Project Download"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/downloadButton" />
</LinearLayout>

This should work:
public class Dialog_Form:DialogFragment
{
private ListView myListView;
private List<string> myList=new List<string> ();
public Dialog_Form ()
{
}
public override View OnCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
base.OnCreateView (inflater, container, savedInstanceState);
myList.Add ("Jason");
myList.Add ("Kenny");
myList.Add ("Tedd");
var view = inflater.Inflate (Resource.Layout.dialog_form, container, false);
myListView = view.FindViewById<ListView> (Resource.Id.myListView);
ArrayAdapter adapter = new ArrayAdapter (Activity, Android.Resource.Layout.SimpleListItem1, myList);
myListView.Adapter = adapter;
// Dialog.Window.SetGravity (GravityFlags.CenterHorizontal | GravityFlags.Top);
var layoutParam = Dialog.Window.Attributes;
layoutParam.Width = ViewGroup.LayoutParams.MatchParent;
layoutParam.X = 80;
layoutParam.Y = 200;
Dialog.Window.Attributes = layoutParam;
return view;
}
public override void OnActivityCreated (Bundle savedInstanceState)
{
Dialog.Window.RequestFeature (WindowFeatures.NoTitle);
base.OnActivityCreated (savedInstanceState);
}
}
Specify the x & y position by setting them in the oncreateview. The x & y position should be calculated by the x & y position from your button + the height & width so it will show it above the button.

Reason for your first Build Error is as explained by SushiHangover, i.e You should be passing an instance of the parent Activity (activity which hosts this fragment) as the first parameter to ArrayAdapter Constructor.
Reason for your run-time (Object reference not set to an instance of an object) Exception is because "Activity" property is null. "Activity" property will have a value only when the Fragment attachment to parent Activity is complete. So essentially, you should not be accessing Activity property from OnCreateView Method. You can initialize your listview either in OnAttach or OnCreate callbacks. I am modifying your code accordingly.
`public class GenerFragmentVM : Fragment
{
ListView lst;
public override void OnCreate (Bundle savedInstanceState)
{
base.OnCreate (savedInstanceState);
lst.SetAdapter(new ArrayAdapter<string> (this.Activity,Resource.Layout.abc_list_menu_item_layout,Resource.Menu.Genres));
}
public override View OnCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
base.OnCreateView (inflater, container, savedInstanceState);
var view = inflater.Inflate (Resource.Layout.abc_list_menu_item_layout, container, false);
lst = view.FindViewById<ListView> (Resource.Id.lst_genre);
//Event click on listview
lst.ItemClick+= delegate(object sender, AdapterView.ItemClickEventArgs e) {
};
return view;
}
}
Passing the Activity of your Fragment as the first arg of the Widget's ArrayAdapter
Added a return of your new view;
Code:
public override View OnCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
base.OnCreateView (inflater, container, savedInstanceState);
var view = inflater.Inflate (Resource.Layout.abc_list_menu_item_layout, container, false);
lst = view.FindViewById<ListView> (Resource.Id.lst_genre);
lst.SetAdapter(new ArrayAdapter<string> (this.Activity,Resource.Layout.abc_list_menu_item_layout,Resource.Menu.Genres));
//Event click on listview
lst.ItemClick+= delegate(object sender, AdapterView.ItemClickEventArgs e) {
};
return view;
}

Fragment Shared Element showing abnormal behaviour in transition

Here is my code:
DetailsFragment fragment = new DetailsFragment();
Transition changeTransform = TransitionInflater.from(getActivity()).inflateTransition(R.transition.change_image_transform);
Transition explodeTransform = TransitionInflater.from(getActivity()).
inflateTransition(android.R.transition.explode);
setSharedElementReturnTransition(changeTransform);
setExitTransition(explodeTransform);
// Setup enter transition on second fragment
fragment.setSharedElementEnterTransition(changeTransform);
fragment.setEnterTransition(explodeTransform);
FragmentManager manager = ((Activity)mContext).getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.layoutView, fragment).addToBackStack(fragment.getClass().getSimpleName())
.addSharedElement(view.findViewById(R.id.itemView), "view");
fragment.commit();
In DetailsFragment giving the same transition name("view" as Assign a Common Transition Name) in Layout for ImageView but I not able to see any transition on Android Lollipop.
I have already declared the manifests file style for (Enable Window Content Transitions) -
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="android:windowContentTransitions">true</item>
</style>
I have searched a lot but didn't get answer.
First need to Create
transition directory under project res directory.
Create change_image_trans.xml under transition directory.
<?xml version="1.0" encoding="utf-8"?>
<transitionSet>
<changeTransform/>
<changeBounds/>
</transitionSet>
Activity like this -
public class DemoActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fragment);
ListFragment listFragment = new ListFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, listFragment)
.commit();
}
}

List View in a fragment is not working?

I am using the following code for using a listview in a fragment. I don't know why it is not working?
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_home, container, false);
SharedPreferences allcontactssharedpreferences = getActivity().getSharedPreferences("ALL_LIST_FOR_CONTROL", Context.MODE_PRIVATE);
Map<String,?> keys = allcontactssharedpreferences.getAll();
for(Map.Entry<String,?> entry : keys.entrySet()){
Toast.makeText(getActivity(),entry.getKey(),Toast.LENGTH_LONG).show();
if ( entry.getKey() != null)
AllContacts.add(entry.getKey());
}
listView = (ListView)view.findViewById(R.id.theListOfHistoryControl);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,AllContacts);
listView.setAdapter(adapter);
return view;
}
I tried the follwing solving, but it didn't work either: List View in Fragment not working
#Override

if ( entry.getKey() != null)
AllContacts.add(entry.getKey());
}
// listView = (ListView)view.findViewById(R.id.theListOfHistoryControl);
//

return view;
}
public void onViewCreated(View view, Bundle savedInstanceState) {
listView = (ListView)view.findViewById(R.id.theListOfHistoryControl);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,AllContacts);
listView.setAdapter(adapter);
}

Here is my java file that shows the listview and

savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
listView = (ListView)view.findViewById(R.id.listView);
listView.setOnItemClickListener(this);
getActivity().getActionBar().setTitle(R.string.title_forms);
TextView details = (TextView)view.findViewById(R.id.detail_header);
details.setVisibility(View.VISIBLE);
return view;
}
Here is one of my fragment that has onItemClick Listener
public class ListFragment extends Fragment implements AdapterView.OnItemClickListener {
public static final String TAG = "ListFragment";
private ListView listView;
private ArrayList<String> testIds;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
tripIds = new ArrayList<String>();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
listView = (ListView) view.findViewById(R.id.listView);
listView.setOnItemClickListener(this);
registerForContextMenu(listView);
return view;
}
Here is my onItemClick :
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
chooseTest(testIds.get(position));
String selectedTestId = testIds.get(position);
Helpers.saveToSharedPreferences(getActivity(),
Constants_Prefs.SELECTED_TOP_LEVEL_RECORD,
Constants_Keys.SELECTED_TEST_ID,
selectedTestId);
I don't know how can I get that information
FormTypeListFragment passDataTo = new FormTypeListFragment();
Bundle bundle = new Bundle();
bundle.putString("DATA", selectedTestId);
passDataTo.setArguments(bundle);
}
Before launching your fragment to display selected item use setArguments() method to add key value pair of string in your case, Then in your fragment on createView use fragments method getArguments() to retain your passed string
Pass the value in bundle as :
Set :
YourFragment fragmnt = new YourFragment ();
Bundle bundle = new Bundle();
bundle.putString("item","name");
fragmnt.setArgument(bundle);
Get :
Then in your Fragment, retrieve the data (e.g. in onCreate()) with:
Bundle bundle = this.getArguments();
String myValue = bundle.getInt("item", "");

achartengine: How to add chart to fragment in Tabs

I want to show a Button and a PieChart below in a tab.
Thats the code I worked with: https://github.com/JakeWharton/ActionBarSherlock/blob/master/samples/fragments/src/com/actionbarsherlock/sample/fragments/FragmentTabs.java
Instead of the CountingFragment etc. I implemented my own.
I'm not sure what to
My xml:
fragment_graph_categories.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_graph_categories"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/button_filter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_filter" />
</LinearLayout>
And that's my "Tab" attached to the TabManger
public class GraphCategories extends SherlockFragmentActivity {
GraphCategoriesFragment mCategoriesFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {

//mCategoriesFragment.onResumeRedraw();
}
}
//notice Inner class
public static class GraphCategoriesFragment extends SherlockFragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//View mChartView = inflater.inflate(R.layout.hello_world, container, false);
View rlayout = inflater.inflate(R.layout.fragment_graph_categories, container, false);
//? rlayout = new LinearLayout(getActivity());
return rlayout;
}
}
}
But im not sure what to inflate at the fragments onCreateView or if I need a FrameLayout in my xml?
I tried some options but don't figured it out.
