标签: multichoiceitems

我在我的应用程序中使用Dialog以允许用户进行多项选择,这是我的代码:

    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Build an AlertDialog
            AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

            // String array for alert dialog multi choice items
            String[] colors = new String[]{
                    "Red",
                    "Green",
                    "Blue",
                    "Purple",
                    "Olive"
            };

            // Boolean array for initial selected items
            final boolean[] checkedColors = new boolean[]{
                    false, // Red
                    false, // Green
                    false, // Blue
                    false, // Purple
                    false // Olive

            };

            // Convert the color array to list
            final List<String> colorsList = Arrays.asList(colors); …

我正在遵循使用上下文操作模式的官方指南，如下所示：

    listView.setChoiceMode(AbsListView.CHOICE_MODE_MULTIPLE_MODAL);
    listView.setMultiChoiceModeListener(new AbsListView.MultiChoiceModeListener() {

        @Override
        public void onItemCheckedStateChanged(ActionMode mode, int position, long id, boolean checked) {
        }

        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            MenuInflater inflater = mode.getMenuInflater();
            inflater.inflate(R.menu.shelf_context, menu);
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            return true;
        }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            // some processing...
            return true;
        }

        @Override
        public void onDestroyActionMode(ActionMode mode) {
        }
    });

我的 listView 位于 aFragment内， a位于 a内 …
