本文主要是介绍android铃声总结,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
感谢 大明同志辛苦制作。最近研究源码程序,改了改手机短信铃声的源码,总结了下铃声的代码,写个activity继承PreferenceActivity有:手机短信铃声,手机铃声,闹钟铃声,还有sdcard中的铃声,通过选择相应的铃声,然后读取到xml文件里面,通过读取preference.xml文件,intent传个参数进去intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, phoneUri);打开对话框的时候就默认选中上次被选中的音乐。程序流程:在onCreate()方法中加入addPreferencesFromResource(R.xml.preferences);加载xml文件。@Override重写onPreferenceTreeClick()方法,处理点击事件,在打开对话框铃声的时候,先读取xml文件,判断是否有值,如果有值,就传值intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, phoneUri);然后进行选择铃声。通过onActivityResult()接受传递过来的uri,系统默认的铃声是通过data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);方法来获取uri的,而sdcard中的铃声通过Uri pickedUri = data.getData();来获得选中的uri的,再然后通过editor.commit(); 来提交接受过来的uri和音乐的名字整个流程大概就是这样。
