Popup menu when a button is pressed in action.

I am trying to implement an action bar in which one of the buttons on a click displays a pop-up menu. Here is the menu. XML (menu items on the action bar)

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@+id/search"
    android:icon="@drawable/ic_action_search"
    android:orderInCategory="0"
    android:showAsAction="always"
    android:title="@string/menu_search"/>
<item
    android:id="@+id/refresh"
    android:icon="@drawable/ic_action_refresh"
    android:orderInCategory="1"
    android:showAsAction="always"
    android:title="@string/menu_refresh"/>


 <Item
    android:id="@+id/popup"
    android:icon="@drawable/ic_action_search"
    android:onClick="showPopup"
    android:orderInCategory="1"
    android:showAsAction="always"
    android:title="@string/menu_search" />

I want to show a popup menu when an element with the identifier "@ + id / popup" is clicked.

here is the XML for the popup menu

<menu xmlns:android="http://schemas.android.com/apk/res/android" >

<item
    android:id="@+id/item1"
    android:icon="@drawable/ic_action_search"
    android:orderInCategory="0"
    android:showAsAction="always"
    android:title="@string/menu_search"/>
<item
    android:id="@+id/item2"
    android:icon="@drawable/ic_action_search"
    android:orderInCategory="1"
    android:showAsAction="always"
    android:title="@string/menu_search"/>

here the onClick method for the button is used

public void showPopup(View v) {
    PopupMenu popup = new PopupMenu(this, v);
    MenuInflater inflater = popup.getMenuInflater();
    inflater.inflate(R.menu.overflow, popup.getMenu());
    popup.show();
}

And the problem is that when you click this button, a popup does not appear. Need help people.

I found a solution to this. Instead of using the XML menu to inflate the popup menu, I created an XML layout file.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#8b8989"
android:orientation="vertical"
android:padding="10dip" >

<TextView
    android:id="@+id/menuItem1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dip"
    android:text="@string/menu1" />

<TextView
    android:id="@+id/menuItem2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dip"
    android:text="@string/menu2" />
<TextView
    android:id="@+id/menuItem3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="10dip"
    android:text="@string/menu3" />
</LinearLayout>

and I changed the onClick method

public void showPopup(View v) {
    LayoutInflater inflater = (LayoutInflater) MainActivity.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        PopupWindow pw = new PopupWindow(inflater.inflate(
                R.layout.overflow_layout, null, false), 300, 400, true);
        pw.showAtLocation(findViewById(R.id.container), Gravity.CENTER, 0,
                0);
}

This solved the problem.

. Java , .

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu items for use in the action bar
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main, menu);
        return super.onCreateOptionsMenu(menu);
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle presses on the action bar items
       // View v = findViewById(R.id.f);
        switch (item.getItemId()) {
            case R.id.top:
                //action

            default:
                return super.onOptionsItemSelected(item);
        }
    }

"top" xml , . , , .

Since the popup menu is MENU, you must handle this by doing "onOptionsItemSelected". You can tell what to do for each menu item. It will replace the "onClick" option that you have defined and will be called automatically.

Try changing 'this' to getActivity ().

public void showPopup(View v) {
    PopupMenu popup = new PopupMenu(getActivity(), v);
    MenuInflater inflater = popup.getMenuInflater();
    inflater.inflate(R.menu.overflow, popup.getMenu());
    popup.show();
}

Hope this helps .. !!

android:onClick="popup"

maybe you should change it to android:onClick="showPopup"?
