android:imeOptions属性(转)
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 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

在这里设置的imeOptions如何使用呢?如下面的代码,让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。这样我们就可以根据不同的EditText来实现不同的软键盘右下角功能键。
