Android to implement button click events by listening EditText

If you don't have access to a third-party input device, click the button and then just find your buttons and then:

Button.performclick ();

You can do it.

So if you use a third-party input method, there are times when listening is not so easy:

The following scenarios are:

External input service, just throw me a string of characters, I get the character after the Execute button event

The code is as follows:

  edittext1.addtextchangedlistener (New textwatcher () {              @Override              public void aftertextchanged (editable s)  {                 LOG.D (tag,  "aftertextchanged");             }              @Override             public  void beforetextchanged (charsequence s, int start, int count,                                             int&nBsp;after)  {                 LOG.D (tag,  "beforetextchanged:"  + s +  "-"  + start +  "-"  + count +  "-"  + after);             }             @Override              public void ontextchanged ( charsequence s, int start, int before,                                        int count)  {                 if (S.length () >5)  {                    LOG.D (TAG,  " OnTextChanged: " + s + "-" + "-" + start + "-" +  before +  "-"  + count);                                     toast.maketext (context, s +  "",  Toast.LENGTH_LONG). Show ();//                     EditText editText3 =  (EditText)  findviewbyid (r.id.et_3);                      Button button =  (Button)  findviewbyid (r.id.bu_1);             &nBsp;       button.performclick ();                 }             }        });

It is important to note that

OnTextChanged

Method must give a qualified parameter, otherwise it will continue to execute, forming a dead loop, the program will exit unexpectedly.

I'm writing it here.

if (S.length () >5)
