android - 从选项卡布局调用Intent.ACTION_DIAL

Question

我们如何从选项卡布局中调用Intent.ACTION_DIAL

我的代码是

 Resources res = getResources(); // Resource object to get Drawables
        TabHost tabHost = getTabHost(); // The activity TabHost
        TabHost.TabSpec spec; // Resusable TabSpec for each tab
        Intent intent; // Reusable Intent for each tab


    // Create an Intent to launch an Activity for the tab (to be reused)
        intent = new Intent(Intent.ACTION_DIAL);

        // Initialize a TabSpec for each tab and add it to the TabHost
        spec = tabHost
            .newTabSpec("contacts")
            .setIndicator("Contacts",
                res.getDrawable(R.drawable.tab_contacts))
            .setContent(intent);

        tabHost.addTab(spec);

但是该应用显示异常

看来您有与此人相同的问题:http://www.mail-archive.com/android-beginners@googlegroups.com/msg14856.html

除非它具有相同的UserID，否则您不能自己使用其他应用程序中的代码。邮件列表中提到使用SharedUserID(http://developer.android.com/guide/topics/security/security.html#userid)欺骗它，但我怀疑这样做是否可行。

总而言之，除非您为应用程序授予根访问权限，否则我认为这是不可能的。
