在最终得到的答复是：

安卓inputType =textShortMessage

android:inputType="textShortMessage"

新生产线的关键就变成了钥匙取出表情符号键盘。唯一的狡辩是从键盘上新线键消失与此配置（之前，你可以长preSS来绘文字/新线之间选择，但现在它只是表情符号）。

The new line key becomes a key to take out the emoji keyboard. The only quibble is the 'new line' key from the keyboard disappears with this configuration (before you could long press to choose between emoji/new line but now it's only emoji).
