Android修改输入法Enter的文本

EditText设置Enter的文字有以下属性：

一：布局设法（android:imeOptions="actionSearch" android:singleLine="true"）：

android:singleLine="true"这个必须要加，不然不会生效。

1. actionUnspecified  未指定，对应常量EditorInfo.IME_ACTION_UNSPECIFIED.
2. actionNone 没有动作,对应常量EditorInfo.IME_ACTION_NONE 
3. actionGo 去往，对应常量EditorInfo.IME_ACTION_GO 
4. actionSearch 搜索，对应常量EditorInfo.IME_ACTION_SEARCH 
5. actionSend 发送，对应常量EditorInfo.IME_ACTION_SEND
6. actionNext 下一个，对应常量EditorInfo.IME_ACTION_NEXT
7. actionDone 完成，对应常量EditorInfo.IME_ACTION_DONE

二：代码设法：

et.setSingleLine();这个必须要加，不然不会生效。

1. et1.setImeOptions(EditorInfo.IME_ACTION_UNSPECIFIED);
2. et1.setImeOptions(EditorInfo.IME_ACTION_NONE);
3. et1.setImeOptions(EditorInfo.IME_ACTION_GO);
4. et1.setImeOptions(EditorInfo.IME_ACTION_SEARCH);
5. et1.setImeOptions(EditorInfo.IME_ACTION_SEND);
6. et1.setImeOptions(EditorInfo.IME_ACTION_NEXT);
7. et1.setImeOptions(EditorInfo.IME_ACTION_DONE);

上面效果出来了，那么我们能不能来自定义这个按钮的事件呢？答案是肯定的:

关键代码：

 <EditText
        android:id="@+id/et7"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:ems="10"
        android:hint="搜索"
        android:imeOptions="actionSearch"
        android:singleLine="true" />

et7.setOnEditorActionListener(new OnEditorActionListener() {

			@Override
			public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
				boolean isClick = event != null && event.getKeyCode() == KeyEvent.KEYCODE_ENTER;
				if (actionId == EditorInfo.IME_ACTION_SEARCH || isClick) {
					return true;
				}
				return false;
			}
		});

下面是完整代码：
