Question

Android. Drop-down menu by clicking on the icon

How can I make this drop-down menu in the upper right corner. Does anyone have any lessons on this topic?

In Place Toast.makeText(FeedActivity.this, "HELLO", Toast.LENGTH_LONG).show();, I want to implement what @katso wrote

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    switch (id) {
        case android.R.id.home:
            mDrawerLayout.openDrawer(GravityCompat.START);
            return true;
        case R.id.menu_filter:
            Toast.makeText(FeedActivity.this, "HELLO", Toast.LENGTH_LONG).show();
            return true;
    }

    return super.onOptionsItemSelected(item);
}

Popup_menu.xml

<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>

Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {

        PopupMenu popup = new PopupMenu(MainActivity.this, button);           
        popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu());
        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();
    }
});
