我是android新手，我需要你的帮助。我试图在警报对话框上显示新的传入消息？并使 Clickable 成为消息中的内容“链接”
这是我的消息活动
public class SecureMessagesActivity extends Activity implements OnClickListener, OnItemClickListener
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setTheme( android.R.style.Theme_Light );
setContentView(R.layout.main);
/**
* You can also register your intent filter here.
* And here is example how to do this.
*
* IntentFilter filter = new IntentFilter( "android.provider.Telephony.SMS_RECEIVED" );
* filter.setPriority( IntentFilter.SYSTEM_HIGH_PRIORITY );
* registerReceiver( new SmsReceiver(), filter );
