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。

actionUnspecified 未指定，对应常量EditorInfo.IME_ACTION_UNSPECIFIED.
actionNone 没有动作,对应常量EditorInfo.IME_ACTION_NONE
actionGo 去往，对应常量EditorInfo.IME_ACTION_GO
actionSearch 搜索，对应常量EditorInfo.IME_ACTION_SEARCH
actionSend 发送，对应常量EditorInfo.IME_ACTION_SEND
actionNext 下一个，对应常量EditorInfo.IME_ACTION_NEXT
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。

et1.setImeOptions(EditorInfo.IME_ACTION_UNSPECIFIED);
et1.setImeOptions(EditorInfo.IME_ACTION_NONE);
et1.setImeOptions(EditorInfo.IME_ACTION_GO);
et1.setImeOptions(EditorInfo.IME_ACTION_SEARCH);
et1.setImeOptions(EditorInfo.IME_ACTION_SEND);
et1.setImeOptions(EditorInfo.IME_ACTION_NEXT);
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() {@Overridepublic 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：布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:gravity="center_horizontal"    android:orientation="vertical" >    <EditText        android:id="@+id/et1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="10dp"        android:ems="10"        android:hint="未指定"        android:imeOptions="actionUnspecified"        android:singleLine="true" />    <EditText        android:id="@+id/et2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="10dp"        android:ems="10"        android:hint="没有动作"        android:imeOptions="actionNone"        android:singleLine="true" />    <EditText        android:id="@+id/et3"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="10dp"        android:ems="10"        android:hint="去往"        android:imeOptions="actionGo"        android:singleLine="true" />    <EditText        android:id="@+id/et4"        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" />    <EditText        android:id="@+id/et5"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="10dp"        android:ems="10"        android:hint="发送"        android:imeOptions="actionSend"        android:singleLine="true" />    <EditText        android:id="@+id/et6"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="10dp"        android:ems="10"        android:hint="下一个"        android:imeOptions="actionNext"        android:singleLine="true" />    <EditText        android:id="@+id/et7"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="10dp"        android:ems="10"        android:hint="完成"        android:imeOptions="actionDone"        android:singleLine="true" /></LinearLayout>
