I
in a fragment1Perform button key event, need to refresh the contents of the textview
About the following

 
BtnC. SetOnClickListener (new View. An OnClickListener () {
@ Override 
Public void onClick (View v) 
{
Textview1. Settext="1111111"; 
//a 
Textview1. Settext="2222222"; 
//a 
Textview1. Settext="3333333"; 
//a 
Textview1. Settext="4444444"; 
} 

In fact, the above code implementation, button interface feign death, textview1 displays only the last of the "4444444"
So I add the following code

 
HandlerThread HandlerThread; 
Private static String="" TT; 

The class HandlerThread extends Thread 
{
Handler mHandler; 
HandlerThread Handler (h) 
{
MHandler=h; 
} 
Public void the run () 
{
Byte status; 
The Message MSG. 
While (true) 
{
Try 
{
Thread.sleep (100); 
} 
Catch InterruptedException (e) {e.p rintStackTrace (); } 
{
MSG=handler. ObtainMessage (0, ""); 
MHandler. SendMessage (MSG); 
} 
} 
} 
} 

Final Handler Handler=new Handler () 
{
Public void handleMessage (Message MSG) 
{
The switch (MSG. What) 
{
Case 0: 

If (TV. Length () & gt; 0) 
{
Textview1. SetText (TV); 
} 
break; 

Default: 

break; 
} 
} 
}; 

BtnC. SetOnClickListener (new View. An OnClickListener () {
@ Override 
Public void onClick (View v) 
{

TT="1111111"; 
//a 
TT="2222222"; 
//a 
TT="3333333"; 
//a 
TT="4444444"; 
} 

Add
in onCreate

 
HandlerThread=new handlerThread (handler); 
HandlerThread. Start (); 

Still no
Only see the last show of "44444444"
Refresh too fast?
Or what reason?
