翻转网格视图项，如windows瓷砖
翻转网格视图项，如windows瓷砖
提问于 2015-05-06 14:12:10
有一个翻转活动(如FlipBoard)，它的适配器中有一个GridView作为项。GridView使用BaseAdapter。现在，我想像windows一样连续翻转GridView的内容。问题是我当前的方法在2组中翻转网格内容，只有当I已经翻转到FlipBoard视图上的最后一项时，这才能工作。
FlipAdapter是来自MainActivity的适配器，它使FlipBoard类似于动画成为可能：
public class FlipAdapter extends BaseAdapter {
public interface Callback {
public void onPageRequested(int page);
}
static class Item {
static long id = 0;
long mId;
public Item() {
mId = id++;
}
long getId() {
return mId;
}
}
private LayoutInflater inflater;
private Context mContext;
private int h;
private Callback callback;
private List<Item> items = new ArrayList<Item>();
public FlipAdapter(Context context, int height) {
mContext = context;
h = height;
inflater = LayoutInflater.from(context);
for (int i = 0; i < 2; i++) {
items.add(new Item());
}
}
public void setCallback(Callback callback) {
this.callback = callback;
}
@Override
public int getCount() {
return 2;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return items.get(position).getId();
}
@Override
public boolean hasStableIds() {
return true;
}
ViewHolder holder;
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.page, parent, false);
holder.gridView = (GridView) convertView.findViewById(R.id.home_grid);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.gridView.setAdapter(new HomeAdapter(mContext, h));
holder.gridView.setVerticalScrollBarEnabled(false);
holder.gridView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_MOVE) {
return true;
}
return false;
}
});
holder.gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.e("index:", ""+holder.gridView.getChildCount());
}
});
contAnimate();
return convertView;
}
static class ViewHolder {
GridView gridView;
}
static int lastTile = 0;
int index = 0;
public void contAnimate() {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
while (lastTile == index)
index = 0 + new Random().nextInt(6);
lastTile = index;
ViewFlipper viewFlipper = (ViewFlipper) holder.gridView.getChildAt(index);
Animation animation = AnimationUtils.loadAnimation(mContext, R.animator.card_flip_right_out);
viewFlipper.setAnimation(animation);
viewFlipper.startFlipping();
contAnimate();
}
}, 5500);
}
}HomeAdapter是包装在FlipView中的GridView的适配器。
public class HomeAdapter extends BaseAdapter {
private LayoutInflater mLayoutInflater;
private Context mContext;
private int h;
public HomeAdapter(Context context, int height) {
mContext = context;
mLayoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
h = height;
}
@Override
public int getCount() {
return 6;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
FunctionHolder holder;
if (convertView == null) {
holder = new FunctionHolder();
convertView = mLayoutInflater.inflate(R.layout.view_flipper, parent, false);
holder.flipper = (ViewFlipper) convertView.findViewById(R.id.flipper);
} else {
holder = (FunctionHolder) convertView.getTag();
}
View topView = mLayoutInflater.inflate(R.layout.first_item, null);
View bottomView = mLayoutInflater.inflate(R.layout.second_item, null);
holder.flipper.addView(topView, 0);
holder.flipper.addView(bottomView, 1);
convertView.setMinimumHeight(h - 74);
convertView.setTag(holder);
return convertView;
}
