嗨，我正在做一个应用程序，因为我有导航抽屉。在导航抽屉内，我是用于搜索的列表视图上方的编辑文本。现在我想为那个edittext编写android键盘搜索键事件。使用过 android:imeOptions="actionSearch"，所以它在安卓键盘上显示搜索按钮。当我点击搜索时，没有任何反应。我尝试了一些代码，但它没有检测到我的编辑文本。如果有人知道，请帮助我。

我的xml：

您可以根据您的目的使用 actioneditlistener 上的 edittext 集。继承人一些代码：

editTextSearch.setOnEditorActionListener(new OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId,
                KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_SEARCH) {
                // do your stuff here
                imageButtonSearch.performClick();
 //I already had a search button inside edittext so I am using it for getting search results
            }
            return false;
        }
    });
