POUpdating Multiple Textbox Java GUI
text
Body
copied!<p>I have an activity or form in which there is one text box called time here. As suggested by experts from this forum I am using runnable to update the TextBox while receiving the data from wifi.</p> <p>My doubt is what to do when I want to update multiple TextBox's. Should I use multiple blocks of runnables like </p> <pre><code> time1.post(new Runnable() { @Override public void run() { time2.setText(s1); } }); time2.post(new Runnable() { @Override public void run() { time2.setText(s2); } }); time3.post(new Runnable() { @Override public void run() { time3.setText(s2); } }); </code></pre> <p>Or some other technique is there to update multiple TextBoxes? My present code is like below.</p> <pre><code>package com.example.cdttiming; public class MainActivity extends Activity { EditText time; String s; Button button; byte[] buffer = new byte[65535]; InetAddress ia = null; byte[] bmessage = new byte[1500]; DatagramPacket dp = new DatagramPacket(bmessage, bmessage.length); MulticastSocket ms = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); time = (EditText) findViewById(R.id.et_time); try { WifiManager wm = (WifiManager)getSystemService(Context.WIFI_SERVICE); WifiManager.MulticastLock multicastLock = wm.createMulticastLock("multicastLock"); multicastLock.setReferenceCounted(true); multicastLock.acquire(); ia = InetAddress.getByName("226.1.1.1"); try { ms = new MulticastSocket(4321); } catch (IOException e) { e.printStackTrace(); } try { ms.joinGroup(ia); } catch (IOException e) { e.printStackTrace(); } ms.setReuseAddress(true); } catch (UnknownHostException e) { time.setText(e.getMessage()); } catch (IOException e) { time.setText(e.getMessage()); } } public void startProgress(View view) { Runnable runnable = new Runnable() { @Override public void run() { while(true) { try { // String str="This is test string"; ms.receive(dp); s = new String(dp.getData(),0,dp.getLength()); char retval[] = s.toCharArray(); } catch (UnknownHostException e) { time.setText(e.getMessage()); } catch (IOException e) { time.setText(e.getMessage()); } ****////// My doubt is here if i have multple strings of data and multiple /// multiple textboxes to update then what to do ???**** time.post(new Runnable() { @Override public void run() { time.setText(s); } }); } // while } }; new Thread(runnable).start(); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } } </code></pre>
