listView显示

[逃0210]

将报文解析出来，放到listview中，无法显示，就报这个：E/SoundPool(288): error loading /system/media/audio/ui/Effect_Tick.ogg

代码：

}

}
}
});
}

et_search = (EditText) findViewById(R.id.et_search);

}

网上有： 问题原因： 同一个AVD，调试了很多歌项目，产生了N多个log文件，这些文件可能产生了影响。 解决办法： 新建一个AVD即可。

额，是我自己的问题。布局文件中，遮挡了listview.

google已经新出了recyclerview来代替listview了，功能更强大效果更好，别再玩listview了
