怎么判断里面有没有dismiss()方法呢？

Question

我用AlertDialog.Builder dialog = new AlertDialog.Builder(this)定义了一个dialog，可是在setOnItemClickListener()里面怎么有没有dismiss()方法呢？AlertDialog.Builder dialog = new AlertDialog.Builder(getApplicationContext());dialog.setTitle("TITLE");dialog.setView(view);dialog.show();listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> adapter, View view, int pos, long id) { dialog.dismiss() // dismiss is not there. }});

你创建的是DialogBuilder而不是Dialog，你应该这样创建dialog:AlertDialog.Builder builder = newAlertDialog.Builder(this);builder.setCancelable(true);builder.setIcon(android.R.drawable.ic_dialog_alert);builder.setTitle("...");builder.setMessage("message");builder.setNegativeButton("OK", null);AlertDialog dlg = builder.create();
