标签: android-tabhost

我需要在单击选项卡时显示进度对话框,

我的代码ID

public class SIPTabWidget extends TabActivity{
 Intent intent;
  @Override
    protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);


    setContentView(R.layout.main);



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



    // Create an Intent to launch an Activity for the tab (to be reused)
    intent = new Intent().setClass(this, ListContacts.class);

    // Initialize a TabSpec for each tab and add it …

我问我们是否可以在另一个类的tabhost上调用setCurrentTab而不是包含tabhost和tabspecs的类？

我们可以放

tabHost.setCurrentTab(1);

在另一个班级而不是这个班级:

public class Main extends TabActivity{

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.v("", "Welcome in Main");
    setContentView(R.layout.tab);

    TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);  // Le TabHost a des Tabs

    TabSpec firstTabSpec = tabHost.newTabSpec("tid1");  // TabSpec: new tab - TabSpec : setContent to the tab
    firstTabSpec.setIndicator("Informations", getResources().getDrawable(R.drawable.database)).setContent(new Intent(this,FirstTab.class));
    tabHost.addTab(firstTabSpec);

    TabSpec secondTabSpec = tabHost.newTabSpec("tid1");
    secondTabSpec.setIndicator("Graphiques", getResources().getDrawable(R.drawable.chart)).setContent(new Intent(this,SecondTab.class));
    tabHost.addTab(secondTabSpec);

    TabSpec thirdTabSpec = tabHost.newTabSpec("tid1");  // tid1 is firstTabSpec Id (used to access outside)
    thirdTabSpec.setIndicator("Réglages", getResources().getDrawable(R.drawable.settings)).setContent(new Intent(this,ThirdTab.class));
    tabHost.addTab(thirdTabSpec);
}

}

我们可以把它变成静态变量吗？我们怎样才能做到这一点？

感谢您的关注!

让我解释一下我的应用程序的结构,在我的应用程序中,我有3个使用Fragments实现的主要选项卡.其中一个主选项卡在其片段中包含3个子选项卡,一个子选项卡包含 listview.现在我想在选择列表中的项目时启动活动.

这是列表视图的onItemClickListener:

lv.setOnItemClickListener(new OnItemClickListener() 
 {

public void onItemClick(AdapterView<?> arg0, View view, int position,long id) 
{
RecordObjects obj=(RecordObjects)lv.getItemAtPosition(position);
String name=obj.getName();
String url=obj.getUrl();
intent=new Intent(getActivity(),player.class);
intent.putExtra("task","Draft");
intent.putExtra("name",name);
intent.putExtra("read_path",url);
startActivityForResult(intent, 0);

}
});

我点击列表项时得到的错误是:

    05-09 16:19:07.723: D/PhoneWindow(7043): couldn't save which view has focus because the focused view android.widget.LinearLayout@44ecc1d8 has no id.
05-09 16:19:07.741: D/AndroidRuntime(7043): Shutting down VM
05-09 16:19:07.741: W/dalvikvm(7043): threadid=3: thread exiting with uncaught exception (group=0x4001b188) …

我正在开发FragmentsTabs,任何人都可以告诉我,如何为每个选项卡维护单独的backstack ......？提前感谢.

我可以在Dialog中使用TabHost吗？我的应用程序扩展了活动(非Tab-Activity).另一个问题是如何在按下选项卡时调用函数.

请给我一个简单的例子.

提前致谢

我正在编写一个使用许多片段的应用程序.我使用了ActionBarSherlock(带ActionBar).为了解决bug#240,我决定切换一个功能正常的实现来使用ActionBarSherlock和TabHost.经过半个小时的工作,它工作正常,除了我在页面之间滑动:相应的选项卡被选中,但没有居中,往往甚至看不到,因此用户无法看到选择了哪个选项卡.

在图片中,您可以看到可见片段("WEEKLY S .."),但标签只有一半可见.下一次滑动只会使"WEEKLY S ..."看起来像"CALENDAR EVENTS",除非我手动滑动TabWidget,否则我不知道选择了哪个Tab.

这是我的activity_main.xml:

<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <HorizontalScrollView 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:fillViewport="true"
            android:scrollbars="none" >

            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:tabStripEnabled="true"
                android:orientation="horizontal" />

        </HorizontalScrollView>

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="0"/>

        <android.support.v4.view.ViewPager
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"/>

    </LinearLayout>

</TabHost>

而我的TabsAdapter与Jake Wharton的FragmentTabsPager示例相同.

欢迎任何建议!

我想将tabhost的默认蓝色更改为红色.

<style name="AppTheme" parent="android:Theme.Light.NoTitleBar">
          <item name="android:tabWidgetStyle">@drawable/tab_indicator_holo</item>
          </style>

tab_indicator_holo.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Non focused states -->
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_holo" />
    <item android:state_focused="false" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/tab_selected_holo" />

    <!-- Focused states -->
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_focused_holo" />
    <item android:state_focused="true" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/tab_selected_focused_holo" />

    <!-- Pressed -->
    <!--    Non focused states -->
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" />
    <item android:state_focused="false" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />

    <!--    Focused states -->
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" />
    <item android:state_focused="true" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />
</selector> …

有没有人遇到过这个错误？

现在我正在尝试从android/eclipse中的标签主机的第一个标签切换到第二个标签.但是在运行模拟器后显示为应用程序Tab_testing意外停止"请稍后重试

任何人都可以找到解决方案吗？

请在下面找到我的来源.

主要来源

public class Tab_testingActivity extends TabActivity 
{
 /** Called when the activity is first created. */

@Override      
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main);

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

   intent = new Intent().setClass(this, Activity_1.class);


    spec = tabHost.newTabSpec("first").setIndicator("First").setContent(intent);
    tabHost.addTab(spec);


    intent = new Intent().setClass(this, Activity_2.class);
    spec = tabHost.newTabSpec("second").setIndicator("Second").setContent(intent);
    tabHost.addTab(spec);

    tabHost.setCurrentTab(0);

    }
    }
