方式一: 利用PackageManager
ImageView mIvIcon;TextView mTvTitle;......PackageManager pm = mContext.getPackageManager();Resources rs = null;try { rs = pm.getResourcesForApplication("com.yf.test");} catch (PackageManager.NameNotFoundException e) { e.printStackTrace();}if (null != rs) { int ivId = rs.getIdentifier("ic_launcher", "mipmap", "com.yf.test"); int tvId = rs.getIdentifier("app_name", "string", "com.yf.test"); mIvIcon.setImageDrawable(rs.getDrawable(ivId)); mTvTitle.setText(rs.getString(tvId));}
方式二:利用目标资源所在的Context
Context remoteContext = null;try { remoteContext = mContext.createPackageContext("com.yf.test", CONTEXT_INCLUDE_CODE | CONTEXT_IGNORE_SECURITY);} catch (PackageManager.NameNotFoundException e) { e.printStackTrace();}if (null != remoteContext) { int ivId = remoteContext.getResources().getIdentifier("ic_launcher", "mipmap", "com.yf.test"); int tvId = remoteContext.getResources().getIdentifier("app_name", "string", "com.yf.test"); mIvIcon.setImageDrawable(remoteContext.getDrawable(ivId)); mTvTitle.setText(remoteContext.getString(tvId));}

1.CONTEXT_INCLUDE_CODE的意思是包括代码,也就是说可以执行这个包里面的代码 CONTEXT_IGNORE_SECURITY的忽略安全警告,如果不加这个标志的话,有些功能是用不了的,会出现安全警告。2.获取不到资源时,原因可能在于android:sharedUserId package="com.yf.test" android:sharedUserId="xxx"
