如何从另一个应用程序访问字符串资源 [英] How to access String resource from another application

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'

有可能！看一下下面的代码.它对我有用.

It is possible! Take a look at the following code. It works for me.

public void testUseAndroidString() {
    Context context = getContext();
    Resources res = null;
    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);
        }
    } catch (NameNotFoundException e) {
        e.printStackTrace();
    }

}
