Answer 1

You are doing a couple of things wrong.

Remove the following attributes from parent LinearLayout

// remove this from parent layouts
android:focusableInTouchMode="true" 

You only use android:focusableInTouchMode="true" on parent ViewGroup so that its contents are read all at once for screen reader users making use of keyboard navigation, remote control or trackball which would require the view to be first selected, then follows and extra action like click an OK to trigger action/focus events.

...

Focusable in touch mode is a property that should be used sparingly and only in very specific situations as it breaks consistency with normal Android behavior.

Unless you expect the above stated behaviour, that line is unnecessary.

Secondly, remove the following attributes from parent LinearLayout. This i guess may be the culprit of your major challenge:

// remove this from parent layouts
android:clickable="true"  

When a view parent is clickable *OR* (focusable *AND* focusableInTouchMode) its onTouch event intercepts that of its children which can cause unexpected behavior preventing the children from being clickable.

Also comment out the following line:

// comment this out
m_PopupWindow.Touchable=(true);
m_PopupWindow.Focusable = true;

Further more you can call immediate request focus on your EditText by adding <requestFocus /> tag in xml

<EditText...>
    <requestFocus />
</EditText>
