在Android标签中更改文本大小

Question

我一直在标签栏中遇到文字大小的问题。下面是图片，

这是我的代码，

MainActivity.java

public class MainActivity extends Activity implements OnTabChangeListener, OnPageChangeListener{  
    private TabHost tabHost;  
    private ViewPager pager; 

 @Override  
 public void onCreate(Bundle savedInstanceState) {  
   super.onCreate(savedInstanceState);  
   setContentView(R.layout.activity_main);  
   tabHost = (TabHost)findViewById(android.R.id.tabhost);  
   pager = (ViewPager) findViewById(R.id.pager);  

   tabHost.setup();  
   TabWidget tabwidget=tabHost.getTabWidget();

   TabSpec spec = tabHost.newTabSpec("tab1");  
   spec.setContent(R.id.tab1);  
   spec.setIndicator("Check In");  
   tabHost.addTab(spec);  

   spec = tabHost.newTabSpec("tab2");  
   spec.setContent(R.id.tab2);  
   spec.setIndicator("Buddies");  
   tabHost.addTab(spec);  

   spec = tabHost.newTabSpec("tab3");  
   spec.setContent(R.id.tab3);  
   spec.setIndicator("Recommendation");  
   tabHost.addTab(spec); 

   spec = tabHost.newTabSpec("tab4");  
   spec.setContent(R.id.tab4);  
   spec.setIndicator("Feed");  
   tabHost.addTab(spec); 

   spec = tabHost.newTabSpec("tab5");  
   spec.setContent(R.id.tab5);  
   spec.setIndicator("Last");  
   tabHost.addTab(spec);

   pager.setAdapter(new MyPagerAdapter(this));  
   pager.setOnPageChangeListener(this);  
   tabHost.setOnTabChangedListener(this);  

 }  
    @Override  
    public void onTabChanged(String tabId){  
         int pageNumber = 0;  
         if(tabId.equals("tab1"))
         {  
              pageNumber = 0;  

         }

         else if(tabId.equals("tab2"))
         {  
              pageNumber = 1;

         }

         else if(tabId.equals("tab3"))
         {  
              pageNumber = 2;  

         }

         else if(tabId.equals("tab4"))
         {  
              pageNumber = 3;  


         }

         else if(tabId.equals("tab5"))
         {  
              pageNumber = 4;  

         }
         else
         {  
              pageNumber = 0;  

         }  

         pager.setCurrentItem(pageNumber);  
    } 

    @Override  
    public void onPageSelected(int pageNumber) {  
         tabHost.setCurrentTab(pageNumber); 

    }
    @Override
    public void onPageScrollStateChanged(int arg0) {


    }
    @Override
    public void onPageScrolled(int arg0, float arg1, int arg2) {


    }
    }

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TabWidget
            android:id="@android:id/tabs"

            <FrameLayout
                android:id="@+id/tab5"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:visibility="gone" />
        </FrameLayout>

        <android.support.v4.view.ViewPager

            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>

</TabHost>

我希望在每个标签中设置全文，我该怎么做？

我一直在尝试使用此代码来更改文本大小并获得此结果，

码

 TextView x = (TextView) tabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title);
   x.setTextSize(10);
   tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 100;

   TextView x1 = (TextView) tabHost.getTabWidget().getChildAt(1).findViewById(android.R.id.title);
   x1.setTextSize(10);
   tabHost.getTabWidget().getChildAt(1).getLayoutParams().width = 90;

   TextView x2 = (TextView) tabHost.getTabWidget().getChildAt(2).findViewById(android.R.id.title);
   x2.setTextSize(10);
   tabHost.getTabWidget().getChildAt(2).getLayoutParams().width = 100;

   TextView x3 = (TextView) tabHost.getTabWidget().getChildAt(3).findViewById(android.R.id.title);
   x3.setTextSize(10);
   tabHost.getTabWidget().getChildAt(3).getLayoutParams().width = 40;

   TextView x4 = (TextView) tabHost.getTabWidget().getChildAt(4).findViewById(android.R.id.title);
   x4.setTextSize(10);
   tabHost.getTabWidget().getChildAt(4).getLayoutParams().width = 40;

结果的形象

但是我想要输出作为此图像

如上图所示，我的标签小部件应该是可移动的，我该怎么做？

Answer 1

TextView x = (TextView) tabHost.getTabWidget().getChildAt(0).findViewById(android.R.id.title);
    x.setTextSize(25);
