在android开发过程中，有时候需要对EditText的软键盘进行监听。当点击软键盘回车位置按键的时候，需要实现 完成、前进、下一项、搜索、发送或其他功能。这就需要开发者对软键盘回车的点击事件进行捕捉。
1.我们需要先在XML文件中设置EditText的android:imeOptions=""属性，
（IME英文全称Input Method Editors，中文名称输入法编辑器）
<EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:imeOptions="actionSearch" android:singleLine="true"/> 注意： 需要设置`android:inputType="text"`或者`android:singleLine="true"`,否则代码中的`setOnEditorActionListener`可能不起作用。
2.在代码中对EditText设置setOnEditorActionListener监听事件。
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {/***** * @param v 可以理解为是向上转型的EditText，可以用来操作当前的EditText* @param actionId 动作标识，是跟EditorInfo.IME_**这里的值对比可以判断执行了什么动作* @param event 跟KeyEvent.ACTION_**比较值判断它的事件* @return 如果不往下执行到此结束，返回true，否则为false。*/@Overridepublic boolean onEditorAction(TextView v, int actionId, KeyEvent event) {if (actionId == EditorInfo.IME_ACTION_SEARCH) {//判断动作标识是否匹配// To do something}return false;}});
上面是对软键盘回车键匹配的步骤，总共就两步，其实挺简单的。
以下是在MIUI系统中搜狗输入法小米版对Enter键的匹配样式。不同的系统，不同的输入法，可能会对Enter键的匹配不同，其他输入法请自行测试。
八个属性的源码+注释。
