[]textview in Android Episode Response click event (spannablestring)

• Project requirements

Click on a small piece of text in the TextView to play a dialog box

• Failed solution

At first, it was using two textview horizontal layout, imagine, when the first TextView quickly occupied a row, still not changed line, the second TextView is likely to have a newline layout problem

• With the problem of spannablestring

Small paragraph text has underline

Click on the text in TextView, the system will be treated as a URL, to the text of the clicked part plus a blue background

• Solution Solutions

public class    Touchablespan extends Clickablespan {private Boolean mispressed;    private int mpressedbackgroundcolor;    private int mnormaltextcolor;    private int mpressedtextcolor; Public Touchablespan (int normaltextcolor, int pressedtextcolor, int pressedbackgroundcolor) {Mnormaltextcolor = no        Rmaltextcolor;        Mpressedtextcolor = Pressedtextcolor;    Mpressedbackgroundcolor = Pressedbackgroundcolor;    The public void setpressed (Boolean isSelected) {mispressed = isSelected;        } @Override public void Updatedrawstate (Textpaint ds) {super.updatedrawstate (DS);        Ds.setcolor (mispressed mpressedtextcolor:mnormaltextcolor); Ds.bgcolor = mispressed?        mpressedbackgroundcolor:0x00eeeeee;    Ds.setunderlinetext (FALSE); } @Overridepublic void OnClick (View widget) {//todo}} 

Class Linktouchmovementmethod extends Linkmovementmethod {private Touchablespan mpressedspan; @Override public boolean ontouchevent (TextView TextView, spannable spannable, motionevent event) {if (event.get            Action () = = Motionevent.action_down) {Mpressedspan = Getpressedspan (TextView, spannable, event);                if (Mpressedspan! = null) {mpressedspan.setpressed (true); Selection.setselection (spannable, Spannable.getspanstart (Mpressedspan), Spannable.getspanend (mPress            Edspan)); }} else if (event.getaction () = = Motionevent.action_move) {Touchablespan Touchedspan = Getpressedspan (            TextView, spannable, event);                if (Mpressedspan! = NULL && Touchedspan! = Mpressedspan) {mpressedspan.setpressed (false);                Mpressedspan = null;            Selection.removeselection (spannable); }}} else {if (Mpressedspan! =NULL) {mpressedspan.setpressed (false);            Super.ontouchevent (TextView, spannable, event);            } Mpressedspan = null;        Selection.removeselection (spannable);    } return true; } Touchablespan Getpressedspan (TextView TextView, spannable spannable, motionevent event) {int x = (int) event.

Finally, don't forget to add

Mstartpagetermscondition.setmovementmethod (New Linktouchmovementmethod ());
