Android中引用其他程序的文本资源超简单方法

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();
    }

}
