标签：des   android   style   blog   class   code   

MainActivity如下:

package cc.c;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.app.LoaderManager.LoaderCallbacks;
import android.content.Context;
import android.content.Loader;
import android.database.Cursor;

 *   Thank you very much

 * 注意事项:
 * 1 Loader是3.0之后才引进来的
 * 2 若在3.0之前使用Loader那么Activity须继承FragmentActivity
 * 3 在Loader内部封装好了ContentOberver
