android 键盘 send按钮

默认情况下软键盘右下角的按钮为“下一个”，点击会到下一个输入框，保持软键盘

设置 EditView

android:imeOptions="actionDone" ，软键盘下方变成“完成”，点击后光标保持在原来的输入框上，并且软键盘关闭

android:imeOptions="actionSend" 软键盘下方变成“发送”，点击后光标移动下一个
EditText实现setOnEditorActionListener，在onEditAction方法中actionId就对应我们设置的imeOptions。系统默认的actionId有：EditorInfo.IME_NULL、EditorInfo.IME_ACTION_SEND、EditorInfo.IME_ACTION_DONE等。

etEmail.setOnEditorActionListener( this );

@Override
   public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
   switch (actionId){
   case EditorInfo.IME_NULL:
System.out.println( "null for default_content: " + v.getText() );
   break ;
   case EditorInfo.IME_ACTION_SEND:
System.out.println( "action send for email_content: "   + v.getText());
   break ;
   case EditorInfo.IME_ACTION_DONE:
System.out.println( "action done for number_content: "   + v.getText());
   break ;
}
   //Toast.makeText(this, v.getText()+"--" + actionId, Toast.LENGTH_LONG).show();
   return true ;
}

email.setImeOptions( EditorInfo.IME_ACTION_DONE) 或者
< EditText android:text = "" android:id = "@+id/email_content"
   android:layout_width = "fill_parent" android:layout_height = "wrap_content"
   android:inputType = "text|textEmailAddress"
   android:imeOptions = "actionSend" > EditText >
