如何在Android中自定义Spinner

这可能会帮助你

MultiSelectionSpinner

<com.extra.MultiSelectionSpinner android:id="@+id/input1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="2dp" /> MultiSelectionSpinner spinner=(MultiSelectionSpinner)findViewById(R.id.input1); List<String> list = new ArrayList<String>(); list.add("List1"); list.add("List2"); spinner.setItems(list);

多select微调:

1-在你自己的xml中创build一个微调,像这样

  <Spinner android:id="@+id/mySpinner" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_marginTop="1dp"/> 

2 – 为这样的微调创build一个自定义的细节:

 public class AdapterTagSpinnerItem extends ArrayAdapter<TagListSimpleSearch> { private LayoutInflater mInflater; private List<TagListSimpleSearch> listState; public Spinner mySpinner = null; public AdapterTagSpinnerItem(Context context, int resource, List<TagListSimpleSearch> objects, Spinner mySpinner) { super(context, resource, objects); this.listState = objects; this.mySpinner = mySpinner; mInflater = LayoutInflater.from(context); } @Override public View getDropDownView(int position, View convertView, ViewGroup parent) { return getCustomView(position, convertView, parent); } @Override public View getView(int position, View convertView, ViewGroup parent) { return getCustomView(position, convertView, parent); } public View getCustomView(final int position, View convertView, ViewGroup parent) { String text = ""; final ViewHolder holder; if (convertView == null) { holder = new ViewHolder(); mInflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); convertView = mInflater.inflate(R.layout.spinner_item, null, false); holder.mTextView = convertView.findViewById(R.id.tvSpinnerItem); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } /** * check position , if position is zero we put space on top of list of spinner */ if ((position == 0)) text = oneSpace; /** * check position , if position is one we put cross mark before text to show that position used to be for clear all selected items on spinner */ else if ((position == 1)) text = " " + String.valueOf((char) crossMarkAroundBox) + " " + listState.get(position).getTagText(); /** * check position , if position is two we put check mark before text to show that position used to be for select all items on spinner */ else if ((position == 2)) text = " " + String.valueOf((char) tikMarkAroundBox) + " " + listState.get(position).getTagText(); /** * check position , if position is bigger than two we have to check that position is selected before or not and put check mark or dash before text */ else { if (listState.get(position).isSelected()) { text = " " + String.valueOf((char) tikMark) + " " + listState.get(position).getTagText(); } else { text = " " + String.valueOf(dash) + " " + listState.get(position).getTagText(); } } holder.mTextView.setText(text); holder.mTextView.setTag(position); holder.mTextView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { /** * if you want open spinner after click on text for first time we have to open spinner programmatically */ mySpinner.performClick(); int getPosition = (Integer) v.getTag(); listState.get(getPosition).setSelected(!listState.get(getPosition).isSelected()); notifyDataSetChanged(); /** * if clicked position is one * that means you want clear all select item in list */ if (getPosition == 1) { clearList(); } /** * if clicked position is two * that means you want select all item in list */ else if (getPosition == 2) { fillList(); } } }); return convertView; } /** * clear all items in list */ public void clearList() { for (TagListSimpleSearch items : listState) { items.setSelected(false); } notifyDataSetChanged(); } /** * select all items in list */ public void fillList() { for (TagListSimpleSearch items : listState) { items.setSelected(true); } notifyDataSetChanged(); } /** * view holder */ private class ViewHolder { private TextView mTextView; } } 

3-现在你必须为适配器创build对象

 public class TagListSimpleSearch { private String TagId; private String TagText; private boolean selected; public String getTagId() { return TagId; } public void setTagId(String TagId) { this.TagId = TagId; } public String getTagText() { return TagText; } public void setTagText(String tagText) { TagText = tagText; } public boolean isSelected() { return selected; } public void setSelected(boolean selected) { this.selected = selected; } } 

在您的活动中使用4填充旋钮适配器

 public static String oneSpace =" "; public static int tikMark =0X2714; public static int crossMark =0X2715; public static int tikMarkAroundBox =0X2611; public static int crossMarkAroundBox =0X274E; public static String dash ="-"; private Spinner mySpinner; mySpinner= (Spinner) findViewById(R.id.mySpinner); List<TagListSimpleSearch> tagsNames = new ArrayList<>(); TagListSimpleSearch tagSpecific=new TagListSimpleSearch(); tagSpecific.setTagId("0"); tagSpecific.setTagText(oneSpace); tagsNames.add(tagSpecific); tagSpecific=new TagListSimpleSearch(); tagSpecific.setTagId("1"); tagSpecific.setTagText("select All Items"); tagsNames.add(tagSpecific); tagSpecific=new TagListSimpleSearch(); tagSpecific.setTagId("2"); tagSpecific.setTagText("remove All Items"); tagsNames.add(tagSpecific); tagSpecific=new TagListSimpleSearch(); tagSpecific.setTagId("0"); tagSpecific.setTagText("Item 0"); tagsNames.add(tagSpecific); tagSpecific=new TagListSimpleSearch(); tagSpecific.setTagId("1"); tagSpecific.setTagText("Item 1"); tagsNames.add(tagSpecific); tagSpecific=new TagListSimpleSearch(); tagSpecific.setTagId("2"); tagSpecific.setTagText("Item 2"); tagsNames.add(tagSpecific); tagSpecific=new TagListSimpleSearch(); tagSpecific.setTagId("3"); tagSpecific.setTagText("Item 3"); tagsNames.add(tagSpecific); final AdapterTagSpinnerItem adapterTagSpinnerItem = new AdapterTagSpinnerItem(this, 0, tagsNames,mySpinner); mySpinner.setAdapter(adapterTagSpinnerItem);
