显示一个ProgressDialog，然后在线程中取消
mLogin.setOnClickListener(new OnClickListener() {public void onClick(View v) {// TODO Auto-generated method stubmyDialog = new ProgressDialog(LoginActivity.this);myDialog.setMessage("正在与服务器连接");myDialog.setIndeterminate(true);注意这里是DialogInterface.OnClickListener()，如果用alt+/提示没有这个方法，手动加，否则只有OnClickListener()，就会提示参数不对myDialog.setButton("取消", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stub}});myDialog.show();//myDialog = ProgressDialog.show(LoginActivity.this,"","正在与服务器连接",true);new myThread().start();或者在这里用Handler启动线程/*Handler myHandler = new Handler();myHandler.postDelayed(new Runnable() {public void run() {// TODO Auto-generated method stubmyDialog.cancel();}}, 5000);*//* * 鉴权方法 */auth.verify(mNameEdit.getText().toString(), mPasswordEdit.getText().toString());}});public class myThread extends Thread{public void run(){try { sleep(5000); myDialog.dismiss(); } catch (Exception e) { e.printStackTrace(); }}}
