问题描述
我有一个应用程序"A"和一个应用程序"B".
I have a application 'A' and application 'B'.
说,我在应用程序"A"中有一个字符串资源
Say, I have a string resource in the application 'A'
<\string name="abc">ABCDEF<\/string>
如何从"B"中的活动"中访问abc的值.
How do I access the value of abc from the Activity in 'B'.
我尝试了以下方法.
try {
PackageManager pm = getPackageManager();
ComponentName component = new ComponentName(
"com.android.myhome",
"com.android.myhome.WebPortalActivity");
ActivityInfo activityInfo = pm.getActivityInfo(component, 0);
Resources res = pm.getResourcesForApplication(activityInfo.applicationInfo);
int resId = res.getIdentifier("abc", "string", null);
}
catch(NameNotFoundException e){
}
始终将resId始终返回0.任何人都可以让我知道是否可以从应用程序"B"访问字符串abc.
Always resId is returned 0 always.. Can anyone please let me know if I could access string abc from the application 'B'

try {
//I want to use the clear_activities string in Package com.android.settings
res = context.getPackageManager().getResourcesForApplication("com.android.settings");
int resourceId = res.getIdentifier("com.android.settings:string/clear_activities", null, null);
if(0 != resourceId) {
CharSequence s = context.getPackageManager().getText("com.android.settings", resourceId, null);
Log.i(VIEW_LOG_TAG, "resource=" + s);
}

e.printStackTrace();
}
}
