解决方法：“在列表视图中单击多项目，以保持其颜色不变”

Question

我已经成功实现了带有自定义适配器的列表视图，该适配器显示图片和标题。它还设置为多次单击视图，因此可以选择多个项目，并且数据可以传递到其他活动。我还实现了一项功能，以便当我单击某个项目时其背景会更改颜色。

我唯一无法解决的问题是，当我单击第二个项目时，第一个项目的背景色会变回原来的颜色。我希望所有单击的项目保持颜色不变。

// Assigns the listView variable to the listView in the xml file.
    listView = findViewById(R.id.distortedListViewWorkout);

    // Instantiate the Custom Adapter (currently not being used)
    MyAdapter adapter = new MyAdapter(this, mTitle, images);

    // Instantiates the Adatper with a premade android simple layout and      the title array list.
    listView.setAdapter(adapter);

    //((new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, mTitle)));

    // Enables the user to select multiple items in the listview.
    listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

    // sets an onItemClickListener for the listView
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        /**
         *
         * @param parent
         * @param view
         * @param position
         * @param id
         */
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {


// variable which will capture the title of the item selected in the listView.
            distortionsString = "";

            int userInput = listView.getCount();
            SparseBooleanArray sparseBooleanArray =   listView.getCheckedItemPositions();
            for(int loop = 0; loop < userInput; loop++){
                if(sparseBooleanArray.get(loop)) {
                    distortionsString += listView.getItemAtPosition(loop).toString() + "\n";
                           view.setSelected(true);
                }
            }
        }});
