安卓keycode :KeyEvent.KEYCODE_SEARCH

Question

嗨，我有带有in选项动作搜索的编辑文本，当我点击虚拟键盘中的搜索图标时，我需要调用一个函数，我已经覆盖了onKeydown，但当我按下搜索时，我不会得到控制，我该怎么办？

Answer 1

ed1.setOnEditorActionListener(new OnEditorActionListener() {        
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if(actionId==EditorInfo.IME_ACTION_SEARCH){
            System.out.println("Search pressed.........");
        }
            return false;
        }
    });

Answer 2

search_edit.setOnKeyListener(new OnKeyListener() {

                @Override
                public boolean onKey(View v, int keyCode, KeyEvent event) {
                    System.out.println("The key pressed onkeylistenere is having code: "+keyCode);
                    System.out.println("The key pressed onkeylistenere is having event: "+event);

                    return false;
                }
            });

试一试，然后按“搜索”，获取密钥码并使用
