如何在

actionbar

搜索小部件中触发操作

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle item selection
        switch (item.getItemId()) {
            case R.id.menu_search:
                finish();
                return true;

            default:
                return super.onOptionsItemSelected(item);
        }
    }

进行布局搜索并向其中添加EditText

<EditText
        android:id="@+id/txt_search"
        android:layout_width="400dp"
        android:layout_height="wrap_content"
        android:drawableRight="@drawable/ic_action_search"
        />

                    intent.putExtra("urlid",finurl);

                    startActivity(intent);

                return false;
            }
        });
        return true;
