我需要获得整篇文字,在我的InputMethod类别中向主讲,只有“n”性质,但我不知道案文长度。
getCurrentInputConnection().getTextBeforeCursor(100, 0);
或者由于案文仅从投入中取而代之,而不是从所有特性中取而代之。
引证。 这应当行之有效。
//get the input connection first
InputConnection iconn = getCurrentInputConnection();
//get the total text first.
String full_text=iconn.getExtractedText(new ExtractedTextRequest(),0).text.toString();
//get whole text before the cursor
String before_text=iconn.getTextBeforeCursor(full_text.length(),0).toString();
如上所述,你可以使用数量众多的SapTextBeforeCursor。 如果以同样长的时间返回,你可以尝试获得更大的回报。 但是,有些申请,如三星回来的电子邮件等,总长str! 即便是第1类。
