在android開發過程中，有時候需要對EditText的軟鍵盤進行監聽。當點選軟鍵盤迴車位置按鍵的時候，需要實現 完成、前進、下一項、搜尋、傳送或其他功能。這就需要開發者對軟鍵盤迴車的點選事件進行捕捉。

1. 我們需要先在XML檔案中設定EditText的 android:imeOptions=""屬性，
（IME英文全稱Input Method Editors，中文名稱輸入法編輯器）

  <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
 

        android:imeOptions="actionSearch"
        android:singleLine="true"
         />

 注意： 需要設定`android:inputType="text"`或者`android:singleLine="true"`,
        否則程式碼中的`setOnEditorActionListener`可能不起作用。

2.在程式碼中對EditText設定setOnEditorActionListener監聽事件。

 editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
            /****
             * 
             * @param v 可以理解為是向上轉型的EditText，可以用來操作當前的EditText
             * @param actionId 動作標識，是跟EditorInfo.IME_**這裡的值對比可以判斷執行了什麼動作
             * @param event  跟KeyEvent.ACTION_**比較值判斷它的事件
             * @return  如果不往下執行到此結束，返回true，否則為false。
             */
            @Override
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                 if (actionId == EditorInfo.IME_ACTION_SEARCH) {//判斷動作標識是否匹配
                      // To do something
                }
                return false;
            }
        });

上面是對軟鍵盤迴車鍵匹配的步驟，總共就兩步，其實挺簡單的。
以下是在MIUI系統中搜狗輸入法小米版對Enter鍵的匹配樣式。不同的系統，不同的輸入法，可能會對Enter鍵的匹配不同，其他輸入法請自行測試。

八個屬性的原始碼+註釋。

     */

    /**

    public static final int IME_ACTION_DONE = 0x00000006;

    /**
     * Bits of {@link #IME_MASK_ACTION}: like {@link #IME_ACTION_NEXT}, but

     * can be returned to the app if it sets {@link #IME_FLAG_NAVIGATE_PREVIOUS}.
     */
    public static final int IME_ACTION_PREVIOUS = 0x00000007;
