Question

我们如何从标签布局

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);

但该应用显示异常

请帮助

Answer 1

看起来你有同样的问题：http://www.mail-archive.com/android-beginners@googlegroups.com/msg14856.html

您不能使用自己的其他应用程序中的代码，除非它具有相同的UserID。邮件列表提到用SharedUserID欺骗它（http://developer.android.com/guide/topics/security/security.html#userid），但我怀疑这会有效。

总而言之，除非您授予应用程序root访问权限，否则我会声明它是不可能的。

Answer 2

@Force

我明白了。 当我直接从setOnTabChangedListener

调用startActivity（）时，意图工作正常

这是我的代码

spec = tabHost.newTabSpec("dial")
    .setIndicator("Dialler", res.getDrawable(R.drawable.tab_dial))
    .setContent(intent);
    tabHost.addTab(spec);

并在Tab上更改我给

tabHost.setOnTabChangedListener(new OnTabChangeListener() {

        @Override
        public void onTabChanged(String tabId) {
        System.out.println(" Tab ID:  "+tabId);

        if(tabId.equals("dial")){
            intent =  new Intent(Intent.ACTION_DIAL);
            startActivity(intent);
            tabHost.setCurrentTab(0);
                    }   }
    });

从Tab布局调用Intent.ACTION_DIAL
