What code is needed and where would i place it within my existing code cheers guy's.

public class TrialActivity extends Activity {

private ProgressDialog progressDialog;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    runDialog(5);
}

private void runDialog(final int seconds)
{
    progressDialog = ProgressDialog.show(this, "Please Wait...", "unpacking patch in progress");

    new Thread(new Runnable(){
        public void run(){
            try {
                Thread.sleep(seconds * 1000);
                progressDialog.dismiss();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }).start();

    ((Button)findViewById(R.id.button1)).setOnClickListener(new View.OnClickListener()
    {
      public void onClick(View paramView)
      {

      }

   {

              InputStream in = null;
              OutputStream out = null;
  String filename="savegame.bin";           
  try {    

                in = getResources().openRawResource(R.raw.savegame);
                out = new FileOutputStream("/sdcard/Android/data/com.glu.android.brawler/files/" + filename);
                copyFile(in, out);
                in.close();
                in = null;
                out.flush();
                out.close();
                out = null;
              } catch(Exception e) {
                  Log.e("tag", e.getMessage());
                  Message message = Message.obtain();      
                  message.what = 1;               
                  mHandler.sendMessage(message);
              }       

      }
      private void copyFile(InputStream in, OutputStream out) throws IOException {
          byte[] buffer = new byte[1024];
          int read;
          while((read = in.read(buffer)) != -1){
            out.write(buffer, 0, read);

            Handler mHandler = new Handler() {
                public void handleMessage( Message msg ) 
                {  
                    Toast toast;
                        switch(msg.what) 
                        {          
                           case 1: // for success
                               toast = Toast.makeText(getBaseContext(), "File has been successfully written.", Toast.LENGTH_LONG);
                               toast.show();
                           break;
                           case 0: // for Error
                               toast = Toast.makeText(getBaseContext(), "Error occur during writting file.", Toast.LENGTH_LONG);
                               toast.show();
                           break;

                       }
               };
            };

          }
      }
      }
    );

推荐答案

您可以通过使用的处理程序在code做到这一点。

You can do this by using Handler in your code.

您应该传递到处理器需要显示在OS ....什么消息像下面...

You should pass the message to handler what you need to display on OS....like below...

Message message = Message.obtain();      
message.what = 1;  // success message               
mHandler.sendMessage(message);

＆安培;在处理节目吐司基于这条消息...

& show Toast in your handler based on that message...

Handler mHandler = new Handler() {
     public void handleMessage( Message msg ) 
     {  
         Toast toast;
             switch(msg.what) 
             {          
                case 1: // for success
                    toast = Toast.makeText(getBaseContext(), "File has been successfully written.", Toast.LENGTH_LONG);
                    toast.show();
                break;
                case 0: // for Error
                    toast = Toast.makeText(getBaseContext(), "Error occur during writting file.", Toast.LENGTH_LONG);
                    toast.show();
                break:

            }
    }

}
