因为我也很无聊啊

1.在AndroidManifest.xml文件中的标签内加入下边语句2.新建MusicServer.java类，内容为import android.app.Service; import android.content.Intent;import android.media.MediaPlayer;import android.os.IBinder;public cl

退出的页面添加protected void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); stopService(ServiceIntent);// System.exit(0);}

1./res/drawable 下添加 mybutton.xml 2./res/drawable 下添加 button_bg1.xml <stroke android:width="1px" android:color="#969696" /> <gradient

button.setVisibility(View.INVISIBLE);

android:scrollbars="vertical"

db.rawQuery("SELECT * FROM foodinfo WHERE name='"+name+"'", null);

public class FoodHealthActivity extends Activity { private ImageButton Begin; private Intent ServiceIntent = new Intent("com.angel.Android.MUSIC"); public static String dbName = "foodHealth.db";
