如何更改标签的大小

Question

实际上我已经在我的应用程序中创建了一个选项卡.这里有三个选项卡..但事实是我无法在标签中管理样式更多我希望一个选项卡的大小比其他两个选项卡大我发送我的代码u plese核实..

XML代码:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent" 
android:layout_width="match_parent" 
android:orientation="horizontal"
>

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="5dp">
    <TabWidget
        android:id="@android:id/tabs"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        />
    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp" 
        />

</LinearLayout>

Java代码:

setContentView(R.layout.main);
    Resources res = getResources(); 
    TabHost tabHost = getTabHost();  
    TabHost.TabSpec spec; 
    Intent intent;  

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

    spec = tabHost.newTabSpec("Contacts").setIndicator("Contacts",
                      res.getDrawable(R.drawable.ic_tab_artists))
                  .setContent(intent);
    tabHost.addTab(spec);


    // Do the same for the other tabs
    intent = new Intent().setClass(this, CallActivity.class);
    spec = tabHost.newTabSpec("Call").setIndicator("Call",
                      res.getDrawable(R.drawable.ic_tab_artists))
                  .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, MyInfoActivity.class);
    spec = tabHost.newTabSpec("My Info").setIndicator("MyInfo",
                      res.getDrawable(R.drawable.ic_tab_artists))
                  .setContent(intent);
    tabHost.addTab(spec);

   tabHost.setCurrentTab(2);

这里是用于更改选项卡大小的代码

 Display display = getWindowManager().getDefaultDisplay();
        int width = display.getWidth();

        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

       TabHost mTabHost = getTabHost();

       mTabHost.addTab(mTabHost.newTabSpec("tab_test1")
               .setIndicator((""),getResources().getDrawable(R.drawable.mzl_05))
         .setContent(new Intent(this, NearBy.class)));
       mTabHost.addTab(mTabHost.newTabSpec("tab_test2")
               .setIndicator((""),getResources().getDrawable(R.drawable.mzl_08))
         .setContent(new Intent(this, SearchBy.class)));
               mTabHost.setCurrentTab(0);
               mTabHost.getTabWidget().getChildAt(0).setLayoutParams(new
                 LinearLayout.LayoutParams((width/2)-2,50));
          mTabHost.getTabWidget().getChildAt(1).setLayoutParams(new
                     LinearLayout.LayoutParams((width/2)-2,50));

我希望对你有所帮助.
