小编Sth*_*hlm的帖子

我正在尝试使用gridview(http://www.rogcg.com/blog/2013/11/01/gridview-with-auto-resized-images-on-android)和mediaplayer(http:/ /examples.javacodegeeks.com/android/android-mediaplayer-example/)试图结合我发现的两个教程,这样就可以从GridView中选择一个图像,启动一个播放歌曲的MediaPlayer活动.

GridView教程建议这样做以启用单击:

    gridView.setOnItemClickListener(new AdapterView.OnItemClickListener()
    {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id)
        {
            // this 'mActivity' parameter is Activity object, you can send the current activity.
            Intent i = new Intent(MainActivity.this, AndroidMediaPlayer.class);
            MainActivity.startActivity(i);
        }
    });

但我无法解决问题并得到警告:

Non-static method 'startActivity(android.content.Intent)' cannot be referenced from a static context
