在TabHost新布局 [英] New layouts in TabHost

问题描述

我在我的应用程序中使用tabHost但在一个视图（对应于标签之一）我有一个按钮，要带我到另一个活动，然后另一个布局。现在的问题是：我怎么得到这个新的布局可以继续访问该标签？或更好说了，我怎么加载的FrameLayout这里面新的布局？

I'm using tabHost in my application but in one of the views (corresponding to one of the tabs) I have a button that have to take me to another activity and then another layout. The question is: how do I get this new layout can continue to have access to the tabs? or better say, How do I load this new layout inside the FrameLayout ?.

在此先感谢！

PD：我在Android的是新的，也许是有没有更好的方式来实现我的purpouse不使用TabActivity。我接受任何建议。

Pd: I'm new in Android, maybe is there a better way to achieve my purpouse without using TabActivity. I'm open to any suggestion.

编辑：所以我决定用片段，我建议。现在，我有以下几点：

EDITED: so I decided to use Fragments as I was suggested. And now I have the following:

• AplicationActivity延伸FragmentActivity


• ClientActivity延伸片段


• SettingsActivity延伸片段


• DataClientActivity延伸片段

和以下布局：

• activity_aplicacion


• activity_client


• activity_settings


• activity_data_client

该activity_aplicacion.xml有TabHost，和的FrameLayout和TabWidget从这些我可以去ClientActivity使用SettingsActivity标签。

The activity_aplicacion.xml has TabHost, FrameLayout and TabWidget and from these I can go to ClientActivity and SettingsActivity using tabs.

在ClientActivity我称之为一个按钮，新，当我preSS这个按钮我想去
DataClientActivity。所以，在ClientActivity我也忒以下内容：

In ClientActivity I have a button called "new" and when I press this button I want to go to DataClientActivity. So, in ClientActivity I have te following:

public void onClickNew(View view){
    DataClientActivity fragmentDataClient = new DataClientActivity ();
    final FragmentTransaction ft = getFragmentManager().beginTransaction();
    ft.replace(android.R.id.tabcontent,fragmentDataClient , "fragmentDataClient "); 
    ft.addToBackStack(null);
    ft.commit(); 
 }

但是当我运行我的应用程序，我得到了folling错误：

But when I run my app, I got the folling error:

21 05-04：55：04.780：E / AndroidRuntime（7515）：java.lang.IllegalStateException：找不到在活动课com.nrAplicationActivity对视图类的Andr​​oid的onClick处理程序的方法onClickNew（查看）。 widget.Button ID为buttonNew

05-04 21:55:04.780: E/AndroidRuntime(7515): java.lang.IllegalStateException: Could not find a method onClickNew(View) in the activity class com.n.r.AplicationActivity for onClick handler on view class android.widget.Button with id 'buttonNew'

所以，我有点迷惑分辩了。为什么我要在AplicationActivity的onClickNew方法，而不是在ClientActivity在那里我有按钮？

So I'm a little confuse rigth now. Why should I have the onClickNew method in AplicationActivity and not in ClientActivity where I have the button?

组织编写了：我发现这个解决方案：

EDITED 2: I found the solution for this:

公共类ClientActivity扩展片段{

public class ClientActivity extends Fragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub

    View view = inflater.inflate(R.layout.activity_clientes, container, false);


    **// Register for the Button.OnClick event
    Button b = (Button)view.findViewById(R.id.buttonNew);
    b.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
           // Toast.makeText(Tab1Fragment.this.getActivity(), "OnClickMe button clicked", Toast.LENGTH_LONG).show();
            Log.e("onClickNuevo2 ", "inicio");
            DataClientActivity fragmentDataClient= new DataClientActivity();
            final FragmentTransaction ft = getFragmentManager().beginTransaction();
            ft.replace(android.R.id.tabcontent,fragmentDataClient, "fragmentDataClient"); 
            ft.addToBackStack(null);
            ft.commit(); 
        }
    });**
    return view;
}

}

我只需要登记自己的ClientActivity里面的onClick监听到我的按钮。现在每个完美的作品！非常感谢迪夫亚Motiwala :)并感谢此链接：http://thepseudo$c$cr.word$p$pss.com/2011/10/04/android-tabs-the-fragment-way/#comment-410

推荐答案

您可以使用片段，而不是内部的标签activites。并点击按钮，就可以用一个新的像这样的取代现有的片段：

You can use Fragments instead of activites inside Tab. And on click of button, you can replace existing fragment with a new one like this :

    final FragmentTransaction ft = getFragmentManager().beginTransaction();
    ft.replace(R.id.realtabcontent,newFrag, "New Fragment"); 
    ft.addToBackStack(null);
    ft.commit(); 

在 ft.replace 第一个参数是的FrameLayout到片段进行连接，第二是片段类对象进行instatiated和第三与标签名。

In ft.replace 1st parameter is the frameLayout to which fragment is to be attached, second is the fragment class object to be instatiated and third is the tag name.
