Android: Menù popup with long click?

I need to implement a menù that appears with a long click around a button, so the user can choose with option he wants to take simply sliding toward a certain direction. Is there any way to do that? I have just a setOnLongClickListener with a onLongClick method for now.
btn01.setOnLongClickListener(new View.OnLongClickListener(){
public boolean onLongClick (View view) {
Toast.makeText(getApplicationContext(),"Button 01 long clicked", Toast.LENGTH_SHORT).show();
return true;
}
});

In your Activity :
btn01.setOnLongClickListener(new View.OnLongClickListener(){
public boolean onLongClick (View view) {
registerForContextMenu(btn01);
openContextMenu(btn01);
return true;
}
});
#Override
public void onCreateContextMenu (ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo){
//Context menu
menu.setHeaderTitle("My Context Menu");
menu.add(Menu.NONE, CONTEXT_MENU_VIEW, Menu.NONE, "Add");
menu.add(Menu.NONE, CONTEXT_MENU_EDIT, Menu.NONE, "Edit");
menu.add(Menu.NONE, CONTEXT_MENU_ARCHIVE, Menu.NONE, "Delete");
}
#Override
public boolean onContextItemSelected (MenuItem item){
switch (item.getItemId()) {
case CONTEXT_MENU_VIEW: {
}
break;
case CONTEXT_MENU_EDIT: {
// Edit Action
}
}
}

Focus ListView Items on Button Click

Is it possible to focus the List View Items through any button click?
Like i want that when user click on Floating Action Button then the listview gets focused. I dont want to show checkbox type layout on button clicked. I just want to show the same like in the screenshot on Button click.
What i did is I put the listview onItemLongClick code in the button click blocks but it doesnot work.
fabButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
listViewMessages.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
listViewMessages.setMultiChoiceModeListener(new MultiChoiceModeListener() {
#Override
public void onItemCheckedStateChanged(ActionMode mode, int position,
long id, boolean checked) {
tv.setText(listViewMessages.getCheckedItemCount()+ " Selected");
}
#Override
public boolean onActionItemClicked(final ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.menu:
}
});
mode.finish();
return true;
default:
return false;
}
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
// Inflate the menu for the CAB
MenuInflater inflater = mode.getMenuInflater();
inflater.inflate(R.menu.contextual, menu);
fabButton.setVisibility(View.INVISIBLE);
fabButtonn.setVisibility(View.VISIBLE);
fabButtonn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
for ( int i=0; i< messageListAdapter.getCount(); i++ ) {
listViewMessages.setItemChecked(i, true);
}
}
});
return true;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
fabButton.setVisibility(View.VISIBLE);
fabButtonn.setVisibility(View.GONE);
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// Here you can perform updates to the CAB due to
// an invalidate() request
return false;
}
});
With this code if user clcik on button then he/she has too long press items again to focus the list items which is not what i want. I want to focus items right when button click. Any explanation or link provided will be helpful

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

Checking if a button has been clicked

How to load menu depend on button was clicked? Any idea, solution?
#Override
public boolean onCreateOptionsMenu(final Menu menu) {
menu.clear();
if(button.**isclicked**) {
getMenuInflater().inflate(R.menu.menu_main, menu);
} else {
getMenuInflater().inflate(R.menu.test, menu);
}
return true;
}

Put a boolean field in your activity and change whenever you click button . Depends if its true or false show or not your menu
UPDATE
//declare boolean
boolean clicked=false;
//my button clic
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
//change boolean value
clicked=true;
}
});
//then on another method or where you want
if(clicked)
{
openmenu();
}
else
{
closemenu();
}

try this function
button.isPressed();

Try something like this:
get the button's id
Button button = (Button) findViewById(R.id.button_send);
Adding click event listener
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//do whatever you want
}
});

THe below also work fine.
if(button.isSelected())

EditText setOnCreateContextMenuListener handle result

I have set setOnCreateContextMenuListener to edittext. onCreateContextMenu method is called user long press on edittext. and it opens context menu with 'done' and 'copy' options.
But my question is how can I handle when user select done option or copy options?
Can I get any event when user click on done button or copy button. so I can get selected text via clip manager?
edit.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
#Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
Log.i("TAG", "onCreateContextMenu");//it is printing while context menu is created.
}
});
Thanks.

onContextItemSelected is the event you should use. but it has no View argument to access selected item. Here is a trick to access to selected View.
public class MainActivity extends Activity
{
protected View selectedView;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView lv = (ListView)findViewById(R.id.lv1);
registerForContextMenu(lv);
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
{
this.selectedView = v;
super.onCreateContextMenu(menu, v, menuInfo);
}
#Override
public boolean onContextItemSelected(MenuItem item)
{
switch(item.getId())
{
case R.id.Context_Edit:
// access to view with this.selectedView
break;
case R.id.Context_Delete:
// access to view with this.selectedView
break;
default:
return super.onContextItemSelected(item);
}
return true;
}
}

You can get your both button event like following example
public class MainActivity extends Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView lv = (ListView)findViewById(R.id.lv1);
registerForContextMenu(lv);
}
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
{
super.onCreateContextMenu(menu, v, menuInfo);
if (v.getId() == R.id.lv1)
{
menu.setHeaderTitle("Select Action");
menu.add(0, v.getId(), 0, "Edit");
menu.add(0, v.getId(), 0, "Delete");
}
}
#Override
public boolean onContextItemSelected(MenuItem item)
{
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
if(item.getTitle() == "Edit")
{
// do something
}
if(item.getTitle() == "Delete")
{
// do something
}
return true;
}
Hope it will help you.

You must to override the onLongClick of the editText and setting one CAB. This is example:
private ActionMode.Callback action = new ActionMode.Callback() {
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// TODO Auto-generated method stub
return false;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
// TODO Auto-generated method stub
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
// TODO Auto-generated method stub
return true;
}
#Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
if (item.getItemId() == android.R.id.copy){
ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
Log.i("CAB",String.valueOf(clipboard.getPrimaryClip().getItemAt(0).getText()));
}
return true;
}
};
private EditText edtText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
edtText = (EditText) findViewById(R.id.edtText1);
registerForContextMenu(edtText);
edtText.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
((EditText)v).setTextIsSelectable(true);
((EditText)v).setCustomSelectionActionModeCallback(action);
return false;
}
});
}
