显示选择指针和突出显示文本与longclick的TextView [英] show selection pointers and highlight text in textview with longclick

问题描述

我有我想要实现LongClickListner并选择其中的部分文字TextView中......不过选择指针不会出现，文本不突出显示。
我知道文本被选中，因为当我使用view.getselectionstart（）和view.getselectionend（）它们返回正确的价值观......下面code我使用：

I have a TextView that I want to implement LongClickListner on and select part of the text in it... However selection pointers don't appear and the text is not highlighted. I know the text is selected because when I use view.getselectionstart() and view.getselectionend() they return the right values...below the code I use:

textView.setOnLongClickListener(new OnLongClickListener() {

public boolean onLongClick(View v) {
   Selection.setSelection((Spannable) textView.getText(),5, 10);
   v.setSelected(true);
   return true;
}
 });

这不显示任何东西.....但是，当我尝试登录选择开始和结束：

This doesn't show any thing.....But when I try to log selection start and end:

Log.d("SELECTED TEXT LISTNER",Selection.getSelectionStart(textView.getText())
+ " " +Selection.getSelectionEnd(textView.getText()));

正确的价值观（5,10）返回...任何帮助我该怎么让选择指针和突出显示longclick ??

the right values (5, 10) are returned...any help how I can show selection pointers and highlight on longclick??

推荐答案

在XML：

android:textIsSelectable="true"

编程方式：

textView.setTextIsSelectable(true);

您将不再需要实现自己的 onLongClickListener 作为默认行为是像你描述。

You won't need to implement your own onLongClickListener as the default behaviour is as you described.
