基于Android中获取资源的id和url方法总结

<< string name=”OK”   客户端请求成功 << / string  

//string资源中 名称为OK的 id 获取方式
int strId = getResources().getIdentifier("OK", "string", getPackageName());

<< color name=”colorPrimary”  #3F51B5 << /color  

//color资源中 id 获取
int colorId = getResources().getIdentifier("colorPrimary", "color", getPackageName()); 

<< dimen name=”horizontal_margin” 16dp<< /dimen  

//deimens资源 id 获取
int dimenId = getResources().getIdentifier("horizontal_margin", "dimen", getPackageName());

// mipmap文件夹下的名称为ic_launcher的图片的id   
//mipmap资源id
int mipmapId = getResources().getIdentifier("ic_launcher", "mipmap", getPackageName());

//布局文件的id,比如：R.layout.activity_main    
//布局资源id
int layoutId = getResources().getIdentifier("activity_main", "layout", getPackageName());

//获取系统里的资源id android.R.drawable.ic_menu_share
int id = getResources().getIdentifier("ic_menu_share", "drawable", "android"); //注意，最后一个参数必须是“android

//*获取Res资源的url ContentResolver.SCHEME_ANDROID_RESOURCE*/
Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.mipmap.ic_launcher);
Uri uri = Uri.parse("res:///" + R.mipmap.ic_launcher);
//*获取asset资源的url,ContentResolver.SCHEME_FILE*/
Uri assetUri = Uri.parse("file:///android_asset/" + "qq.png");
