如何禁用長的ListView項單擊

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; 
      } 

     }); 

    } 
} 

在這裏，我不得不通過長按刪除從列表視圖項的程序，而不是刪除項目有長點擊位於ListView項禁用項目。

try代碼像下面

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; 
      } 

     }); 

由於列表視圖替換RecyclerView，所以我建議你使用RecyclerView在未來或與此。

編碼快樂:)

試試這個：

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