如何更改选项卡的大小

Question

实际上我在我的应用程序中创建了一个选项卡。这里有三个选项卡..但问题是我无法在选项卡中管理样式，而且我希望一个选项卡的大小大于我发送的其他两个选项卡代码你请检查它..

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);

Answer 1

这里是改变标签大小的代码

 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));
