I have just created simple pop up with list items but when I click on Grid item it show the pop up at the top of the page like this all I need I want to show this pop up below the item grid
this is my onClick
gridView1.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
//Creating the instance of PopupMenu
PopupMenu popup = new PopupMenu(getActivity(), gridView1);
//Inflating the Popup using xml file
popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());
//registering popup with OnMenuItemClickListener
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(
getActivity(),
"You Clicked : " + item.getTitle(),
Toast.LENGTH_SHORT
).show();
return true;
}
});
popup.show(); //showing popup menu
return true;
}
});
this is my menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/newCheck"
android:title="New Check"/>
<item
android:id="#+id/settleCheck"
android:title="Settle Check"/>
<item
android:id="#+id/newGuestCheck"
android:title="New guest Check"/>
<item
android:id="#+id/discountCheck"
android:title="Discount Check"/>
<item
android:id="#+id/printCheck"
android:title="Print Check"/>
</menu>
You should change this line
PopupMenu popup = new PopupMenu(getActivity(), gridView1);
to this
PopupMenu popup = new PopupMenu(getActivity(), view);
so it will set the anchor for the menu to the proper element.
I have a popup_menu.xml which has 3 item tags as static, so those 3 item values display in pop up menu, But I have one arraylist which has few values that I want to show in that popup menu.
Just I want to show carnames which is available in markersArray instead static Item values which is available in popup_menu.xml
Array List array
for(int i=0; i<markersArray.size(); i++){
String caname = markersArray.get(i).getCarname();
}
popup_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/one"
android:title="One"/>
<item
android:id="#+id/two"
android:title="Two"/>
<item
android:id="#+id/three"
android:title="Three"/>
</menu>
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Click action
System.out.println("Float Icon Clicked");
//Creating the instance of PopupMenu
PopupMenu popup = new PopupMenu(MainActivity.this, fab);
//Inflating the Popup using xml file
popup.getMenuInflater().inflate(R.menu.poupup_menu, popup.getMenu());
//registering popup with OnMenuItemClickListener
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(MainActivity.this, "You Clicked : " + item.getTitle(), Toast.LENGTH_SHORT).show();
return true;
}
});
popup.show();//showing popup menu
}
});
}
Under this line of code
PopupMenu popup = new PopupMenu(MainActivity.this, fab);
Just itterate through your ArrayList and add it to the popup menu like this
for (String s : array) {
popup.getMenu().add(s);
}
I have an XML with two ListView, one with a list of clients filled by a select query (lv_cli) and the other with the details of the client selected (lv_cli_det).
I would like to keep the client selected in the lv_cli while the lv_cli_det show the details.
XML:
<ListView
android:id="#+id/cli_lista"
android:layout_width="512dp"
android:layout_height="wrap_content"
android:fadeScrollbars="false"
>
</ListView>
<ListView
android:id="#+id/cli_lista_det"
android:layout_width="512dp"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/cli_lista"
android:fadeScrollbars="false" >
</ListView>
Java:
Cursor cursor = db.rawQuery("Select NrCl||';'||Nome From Clientes", null);
final ListView t = (ListView)findViewById(R.id.cli_lista);
ArrayAdapter<String> myarrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, listItems);
t.setAdapter(myarrayAdapter);
final ListView td = (ListView)findViewById(R.id.cli_lista_detalhe);
final ArrayAdapter<String> myarrayAdapter2 = new ArrayAdapter<String>(this, android.R.layout.simple_expandable_list_item_1, listItems2);
t.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String item = ((TextView)view).getText().toString();
String[] strArray = item.split("\\;");
cli.load(strArray[0].toString());
td.setAdapter(myarrayAdapter2);
listItems2.clear();
listItems2.add("Nome: " + cli.getNome());
listItems2.add("Morada: " + cli.getMorada());
listItems2.add("Localidade: " + cli.getLoca());
listItems2.add("Código Postal: " + cli.getCp());
listItems2.add("Pais: " + cli.getPais());
listItems2.add("Nif: " + cli.getNif());
listItems2.add("Tel: " + cli.getTel());
listItems2.add("Tlm: " + cli.getTlm());
listItems2.add("Tipo Preço: " + cli.getTipoPvn());
listItems2.add("Cond. Pagamento: " + cli.getCpg());
listItems2.add("Obs: " + cli.getObs());
td.setAdapter(myarrayAdapter2);
myarrayAdapter2.notifyDataSetChanged();
}
});
I found the proper way. It's very simple.
In resource describe following:
android:choiceMode="singleChoice"
android:listSelector="#666666"
(or you may specify a resource link instead of color value)
Programmatical:
listView.setSelector(Drawable selector);
listView.setSelector(int resourceId);
listView.setChoiceMode(int mode);
mode can be one of these: AbsListView.CHOICE_MODE_SINGLE, AbsListView.CHOICE_MODE_MULTIPLE, AbsListView.CHOICE_MODE_NONE (default)
(AbsListView is the abstract ancestor for the ListView class)
P.S. manipulations with onItemClick and changing view background are bankrupt, because a view itself is a temporary object. Hence you must not to track a view.
If our list is long enough, the views associated with scrolled out items will be removed from hierarchy, and will be recreated when those items will shown again (with cached display options, such as background). So, the view we have tracked is now not an actual view of the item, and changing its background does nothing to the actual item view. As a result we have multiple items selected.
To hold the color of listview item when you press it, include the following line in your listview item layout:
android:background="#drawable/bg_key"
Then define bg_key.xml in drawable folder like this:
<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_selected="true"
android:drawable="#color/pressed_color"/>
<item
android:drawable="#color/default_color" />
</selector>
Finally, include this in your ListView onClickListener:
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,long arg3) {
view.setSelected(true);
... // Anything
}
});
This way, only one item will be color-selected at any time. You can define your color values in res/values/colors.xml with something like this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="pressed_color">#4d90fe</color>
<color name="default_color">#ffffff</color>
</resources>
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
for (int j = 0; j < adapterView.getChildCount(); j++)
adapterView.getChildAt(j).setBackgroundColor(Color.TRANSPARENT);
// change the background color of the selected element
view.setBackgroundColor(Color.LTGRAY);
});
Perhaps you might want to save the current selected element in a global variable using the index i.
Simplistic way is,if you are using listview in a xml,use this attributes on your listview,
android:choiceMode="singleChoice"
android:listSelector="#your color code"
if not using xml,by programatically
listview.setChoiceMode(AbsListView.CHOICE_MODE_SINGLE);
listview.setSelector(android.R.color.holo_blue_light);
You need selector like this:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- State when a row is being pressed, but hasn't yet been activated (finger down) -->
<item android:drawable="#color/app_primary_color_light" android:state_pressed="true" />
<!-- Used when the view is "activated". -->
<item android:drawable="#color/app_primary_color" android:state_activated="true" />
<!-- Default, "just hangin' out" state. -->
<item android:drawable="#android:color/transparent" /></selector>
And then set android:choiceMode="singleChoice" to your ListView.
From Avinash Kumar Pankaj's example
View v;
then at oncreate method
v = new View(getActivity());
and then onlistitemclick method i wrote
public void onListItemClick(ListView listView, View view, int position,
long id) {
v.setBackgroundResource(0);
view.setBackgroundResource(R.color.green);
v = view;
}
It worked for me. Thank you.
I replaced
v = new View(getActivity());
to
v = new View(this);
and the code worked well.
It is necessary the xml files 'colors' and 'bg_key' from previous examples too, as well as ListView attribute android:background="#drawable/bg_key"

*please be sure there is no Ripple at your root layout of list view container
add this line to your list view
android:listSelector="#drawable/background_listview"
here is the "background_listview.xml" file
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/white_background" android:state_pressed="true" />
<item android:drawable="#color/primary_color" android:state_focused="false" /></selector>
the colors that used in the background_listview.xml file :
<color name="primary_color">#cc7e00</color>
<color name="white_background">#ffffffff</color>
after these
(clicked item contain orange color until you click another item)
One way you can do this, is to Keep track of the current selected position in your activity:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
currentPosition = position
lv_cli.notifyDataSetChanged();
}
Now, be sure you assign an ID to the parent layout (linearLayout, boxLayout, relativeLayout, .. Whatever you prefer) of your list item.
Then in your ListView you can do something Like this:
layoutBackground = (LinearLayout) convertView.findViewById(R.id.layout_background);
if (YourActivity.this.currentPosition == position) {
layoutBackground.setBackgroundColor(YourActivity.this.getResources().getColor(R.color.hilight_color));
} else{
layoutBackground.setBackgroundResource(R.drawable.list_item_drawable);
}
Basically, you just set the hilight color to the layout as a background when it equals your current selected position.
Notice how I set a drawable background resource when the item is not selected. This could be in your case different (since you posted no code). In my case, this drawable is a selector which makes sure the item is hi-lighted when pressed.
NOTE: This simple code doesn't use a view-holder, but I really
recommend using one.
Use the id instead:
This is the easiest method that can handle even if the list is long:
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
Holder holder=new Holder();
View rowView;
rowView = inflater.inflate(R.layout.list_item, null);
//Handle your items.
//StringHolder.mSelectedItem is a public static variable.
if(getItemId(position)==StringHolder.mSelectedItem){
rowView.setBackgroundColor(Color.LTGRAY);
}else{
rowView.setBackgroundColor(Color.TRANSPARENT);
}
return rowView;
}
And then in your onclicklistener:
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
StringHolder.mSelectedItem = catagoryAdapter.getItemId(i-1);
catagoryAdapter.notifyDataSetChanged();
.....
I have a Gallery with text items. I can change the selected item with the UI or programmatically with setSelection(position). However when I call this method, sometimes the item background is not changed to a selected state. I noticed that if the item called by setSelection is already drawn on the screen then its background is not updated.
Here is the code. Any help is welcome.
public class Test3 extends Activity {
private static String[] items = {"0", "1", "2", "3", "4", "5"};
public void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);
LinearLayout layout = new LinearLayout (this);
layout.setOrientation (LinearLayout.VERTICAL);
setContentView (layout);
final Gallery gallery = new Gallery (this);
layout.addView (gallery);
gallery.setSpacing (0);
gallery.setAdapter (new Adapter (this));
gallery.setSelection (0);
ListView list = new ListView (this);
layout.addView (list);
list.setAdapter (new ArrayAdapter <String> (this,
android.R.layout.simple_list_item_1, items));
list.setOnItemClickListener (new OnItemClickListener () {
public void onItemClick (AdapterView <?> parent, View view, int position,
long id)
{
gallery.setSelection (position);
}
});
}
private class Adapter extends ArrayAdapter <String> {
public Adapter (Context context) {
super (context, android.R.layout.simple_gallery_item, items);
}
public View getView (int position, View convertView, final ViewGroup parent)
{
TextView view = new TextView (getContext ());
view.setText (getItem (position));
view.setBackgroundResource (R.drawable.gallery_background);
view.setGravity (Gravity.CENTER);
view.setLayoutParams (new Gallery.LayoutParams (Test3.this
.getWindowManager ().getDefaultDisplay ().getWidth () / 3,
Gallery.LayoutParams.FILL_PARENT));
return view;
}
}
}
gallery_background.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true" android:drawable="#drawable/highlight_selected" />
<item android:state_checked="true" android:drawable="#drawable/highlight_selected" />
<item android:state_focused="true" android:drawable="#drawable/highlight_selected" />
<item android:state_pressed="true" android:drawable="#drawable/highlight_pressed" />
<item android:drawable="#drawable/highlight_disabled" />
</selector>
Try invalidating the gallery or notifyDataSetChanged the galleries adapter.
I've been playing with Honeycomb for the last week and had a hard time to find something about more than one drop-down list in Action Bar.
I've used this tutorial and successfully added one drop-down list to it. But I don't know how to add another one. Please tell me if you know how to do it.
Thanks.
P.S. also one little this how can I change the position of elements in Action Bar(this is off topic)?
Not sure about Honeycomb but I was able to add two drop down lists to my action bar in JellyBean without using a custom view.
res/menu/main_menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/menu_main_spinner"
android:actionViewClass="android.widget.Spinner"
android:showAsAction="always"/>
<item
android:id="#+id/menu_status_spinner"
android:actionViewClass="android.widget.Spinner"
android:showAsAction="always"/>
</menu>
MyActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate( R.menu.main_menu, menu );
MenuItem mainMenuSpinner = menu.findItem( R.id.menu_main_spinner);
setupMainMenuSpinner( mainMenuSpinner );
MenuItem statusSpinner = menu.findItem( R.id.menu_status_spinner );
setupStatusSpinner( statusSpinner );
return super.onCreateOptionsMenu(menu);
}
private void setupMainMenuSpinner(MenuItem item) {
View view = item.getActionView();
if (view instanceof Spinner) {
Spinner spinner = (Spinner) view;
spinner.setAdapter(ArrayAdapter.createFromResource(this,
R.array.main_menu_options,
android.R.layout.simple_spinner_dropdown_item));
}
}
private void setupStatusSpinner(MenuItem item) {
View view = item.getActionView();
if (view instanceof Spinner) {
Spinner spinner = (Spinner) view;
spinner.setAdapter(ArrayAdapter.createFromResource(this,
R.array.status,
android.R.layout.simple_spinner_dropdown_item));
}
}
You would have to do that yourself. Instead of setNavigationMode(), use setCustomView().
P.S. also one little this how can I change the position of elements in Action Bar(this is off topic)?
Generally, you can't. You control the order (e.g., toolbar buttons via the order they are in your options menu XML). That's pretty much it.
