Question

public class MainActivity extends ActionBarActivity {

    ListView listview;
    String[] subjects = new String[] {"Android","PHP","Blogger","WordPress","SEO"};
    List<String> subject_list;
    ArrayAdapter<String> arrayadapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listview = (ListView)findViewById(R.id.listView1);

        subject_list = new ArrayList<String>(Arrays.asList(subjects));

        arrayadapter = new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, subject_list);

        listview.setAdapter(arrayadapter);

        listview.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {

            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
                // TODO Auto-generated method stub

                subject_list.remove(position);

                arrayadapter.notifyDataSetChanged();

                Toast.makeText(MainActivity.this, "Item Deleted", Toast.LENGTH_LONG).show();

                return true;
            }

        });

    }
}

这里我有一个程序，通过长按，从列表视图中删除项目，而不是删除项目必须通过长按ListView中的项目来禁用项目。

Answer 1

试试这个：

 subject_list.getChildAt(position).setEnabled(false);

Answer 2

尝试以下代码

listview.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {

            @Override
            public boolean onItemLongClick(AdapterView<?> parent, View view,
                                           int position, long id) {
                // TODO Auto-generated method stub

                //subject_list.remove(position);

                if(!view.isEnabled()){
                    return false;
                }
                view.setEnabled(false);
                view.setClickable(false);

                arrayadapter.notifyDataSetChanged();

                Toast.makeText(Main2Activity.this, "Item Deleted", Toast.LENGTH_LONG).show();

                return true;
            }

        });

由于listview已被RecyclerView取代，所以我建议您将来使用RecyclerView或者使用它。
