import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.TextView;
public class A01Activity extends Activity {
 private TextView tv;
 private ImageView iv;
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    tv=(TextView)findViewById(R.id.tv);
    tv.setText("欢迎光临168855");
    iv=(ImageView)findViewById(R.id.iv);
    iv.setBackgroundResource(R.drawable.a);    
  }
}

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class A01_01 extends BroadcastReceiver{
 @Override
 public void onReceive(Context arg0, Intent arg1) {
 // TODO Auto-generated method stub
 Intent i=new Intent(arg0,A01Activity.class);
 i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
 arg0.startActivity(i);
 }
}
