android - onLongClick() 只有在条件为真时才有效

Question

 objImageButton.setOnLongClickListener(new OnLongClickListener() {
               public boolean onLongClick(View v) {
                   if(checkDiscrepancySubmitted(final_position))
                   {       
                   // TODO Auto-generated method stub
                       AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(FragmentActivity.this);
                       alertDialogBuilder
                       .setMessage("Do you wish to delete the logged defect ?")
                       .setCancelable(false)
                       .setPositiveButton("Yes",new DialogInterface.OnClickListener() 
                       {
                           public void onClick(DialogInterface dialog,int id) 
                           {
                               int idButton=objImageButton.getId();
                               EditText objNewEditText=(EditText) findViewById(idButton);
                               objNewEditText.setTextColor(R.color.blue);
                               removeDefect(final_position,idButton,objNewEditText);
                               Toast.makeText(FragmentActivity.this, "Unsaved defects deleted.", Toast.LENGTH_SHORT).show();
                           }
                       })
                       .setNegativeButton("No",new DialogInterface.OnClickListener() {
                           public void onClick(DialogInterface dialog,int id) {
                               dialog.cancel();
                           }
                       });
                       AlertDialog alertDialog = alertDialogBuilder.create();
                       alertDialog.show();
                       return false;
                   }
                   return false;
           }
});

因此，如您所见，在 onLongClick() 中，我有一个条件。仅当此条件为真时，onLongClick() 才起作用。基本上我希望仅当条件为真时才调用 Listener 函数。我如何才能做到这一点？

可能会解决您的问题。您可以将返回类型更改为“true”。
