Android的：如何使键盘的回车键说＆QUOT;搜索＆QUOT;而处理其点击？ [英] Android: how to make keyboard enter button say "Search" and handle its click?

问题描述

我不明白这一点。有些应用程序具有的EditText（文本框），当你触摸它，它带来了屏幕上的键盘，键盘上有一个搜索按钮，而不是一个回车键。

I can't figure this out. Some apps have a EditText (textbox) which, when you touch it and it brings up the on-screen keyboard, the keyboard has a "Search" button instead of an enter key.

我想实现这一点。我如何可以实现搜索按钮和检测的搜索按钮的preSS？

I want to implement this. How can I implement that Search button and detect press of the Search button?

修改：发现如何实现的搜索按钮;在XML中，安卓imeOptions =actionSearch或在Java中， EditTextSample.setImeOptions（EditorInfo.IME_ACTION_SEARCH）; 。但我怎么处理用户pressing的搜索按钮？它有事可做与安卓？imeActionId

Edit: found how to implement the Search button; in XML, android:imeOptions="actionSearch" or in Java, EditTextSample.setImeOptions(EditorInfo.IME_ACTION_SEARCH);. But how do I handle the user pressing that Search button? Does it have something to do with android:imeActionId?

推荐答案

在布局设置输入法选项进行搜索。

In the layout set your input method options to search.

<EditText android:imeOptions="actionSearch" 
    android:inputType="text"/>

在Java中添加编辑器动作监听器。

In the java add the editor action listener.

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if (actionId == EditorInfo.IME_ACTION_SEARCH) {
            performSearch();
            return true;
        }
        return false;
    }
});
