Overfocus in GridView
- by chuck258
I'm trying to implement a GridView that Focuses the next Item and "Overscrolls at the End of a List.
E.g.
1 2 3
4 5 6
7 8 9
I want to scroll 1 2 3 4 5 6 ... just by pressing the right Key. Right now I can only Scroll 1 2 3 and then it stops and I have to scroll with the down Key.
I already tried to set the focusViews in code (In the getView() method of my ArrayList Adapter, that fills the GridView)
view.setId(position);
view.setNextFocusLeftId(position-1);
view.setNextFocusRightId(position+1);
But that doesn't work. I found the boolean *Scroll(int direction) Methods on grepcode
But theese are Package Local and I can't overwrite them. Any suggestions on how to solve this. Can I use another View and get the same Layout as a Gridview?
I also set a OnFocusChangeListener to see what happens with no reaction.
Edit:
I just added this to my MainActivity, but now it seems to onKeyDown only get called when the GridView doesn't handle the KeyEvent (If the Last Item in a row is selected).
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_DPAD_LEFT:
if (focusedView > 0) {
mContainer.setSelection(--focusedView);
Log.v("TEST", focusedView+"");
}
return true;
case KeyEvent.KEYCODE_DPAD_RIGHT:
if (focusedView < mAdapter.getCount() - 1) {
mContainer.setSelection(++focusedView);
Log.v("TEST", focusedView+"");
}
return true;
}
return super.onKeyDown(keyCode, event);
}
Edit 2: This is so f***ing stupid but works so damn fine :D
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_DPAD_LEFT:
mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_UP, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_UP));
mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_RIGHT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_RIGHT));
mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_RIGHT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_RIGHT));
return true;
case KeyEvent.KEYCODE_DPAD_RIGHT:
mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_DOWN, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_DOWN));
mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_LEFT));
mContainer.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_LEFT));
return true;
}
return super.onKeyDown(keyCode, event);
}
I really don't want to post this as Answer, and I really don't want to have to use this Code because it is such a stupid workaround
;TLDR: Help still needed
