8 years ago Nooby android dev, but I hacked together a version that includes all of these
controls as a proof of concept using downloaded source. I copied the image
files already used and modified nav.xml like this:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TableRow>
<ImageButton
android:id="@+id/button_nav_up"
android:src="@drawable/ic_nav_up"
android:layout_column="1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</TableRow>
<TableRow>
<ImageButton
android:id="@+id/button_nav_left"
android:src="@drawable/ic_nav_left"
android:layout_column="0"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageButton
android:id="@+id/button_nav_activate"
android:src="@drawable/ic_nav_activate"
android:layout_column="1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageButton
android:id="@+id/button_nav_right"
android:src="@drawable/ic_nav_right"
android:layout_column="2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</TableRow>
<TableRow>
<ImageButton
android:id="@+id/button_nav_down"
android:src="@drawable/ic_nav_down"
android:layout_column="1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</TableRow>
<TableRow>
<ImageButton
android:id="@+id/button_dvd_left"
android:src="@drawable/dvd_chapter_backward"
android:layout_column="0"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageButton
android:id="@+id/button_dvd_activate"
android:src="@drawable/dvd_menu"
android:layout_column="1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageButton
android:id="@+id/button_dvd_right"
android:src="@drawable/dvd_chapter_forward"
android:layout_column="2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</TableRow>
</TableLayout>
and I added this code (along with declarations and initializations for new
buttons) in PlayBackActivity.java:
// DLB new code to handle navigation buttons
/*
Activate key-nav-activate Enter
Navigate up key-nav-up Up
Navigate down key-nav-down Down
Navigate left key-nav-left Left
Navigate right key-nav-right Right
Go to the DVD menu key-disc-menu Shift-m
Select previous DVD title key-title-prev Shift-o
Select next DVD title key-title-next Shift-b
Select prev DVD chapter key-chapter-prev Shift-p
Select next DVD chapter key-chapter-next Shift-n
*/
else if (v == mButtonNavUp) {
command("command=key&val=nav-up");
}
else if (v == mButtonNavDown) {
command("command=key&val=nav-down");
}
else if (v == mButtonNavLeft) {
command("command=key&val=nav-left");
}
else if (v == mButtonNavRight) {
command("command=key&val=nav-right");
}
else if (v == mButtonNavSel) {
command("command=key&val=nav-activate");
}
else if (v == mButtonDVDChapBack) {
command("command=key&val=chapter-prev");
}
else if (v == mButtonDVDChapForward) {
command("command=key&val=chapter-next");
}
else if (v == mButtonDVDMenu) {
command("command=key&val=disc-menu");
}
The results work well for controlling DVD menus without a d-pad but debouncing
may be needed on some buttons. Since I am completely new to android development
and just a hack at Java I do not know if there is a way to use nav.xml as a
pop-up overlay. Right now I just included it so it displays permanently (which
is fine on my tablet but would be a problem on a phone). If this could be
popped up from the menu I think a button set like this would be a useful
