Android。如何更改标签文本颜色？

Question

我想设置标签文本颜色白色，我找不到任何好的教程。有人能帮我吗？

还有就是我的标签活动：

package com.example.dev.nordugrid; 

import android.app.TabActivity; 
import android.content.Context; 
import android.content.SharedPreferences; 
import android.os.Bundle; 
import android.preference.PreferenceManager; 
import android.util.Log; 
import android.view.View; 
import android.view.Window; 
import android.widget.AdapterView; 
import android.widget.ArrayAdapter; 
import android.widget.Button; 
import android.widget.ListView; 
import android.widget.TabHost; 
import android.widget.TextView; 
import android.widget.Toast; 
import android.widget.TabHost.TabSpec; 
import java.util.ArrayList; 
import java.util.List; 
import java.util.Random; 
@SuppressWarnings("deprecation") 
public class Busena extends TabActivity { 
SharedPreferences prefs; 

TextView proxySuteike, proxyGaliojimas; 
Button button4; 
public int randomInt; 
String stringProxyGaliojimas, stringProxySuteike, stringUzduotiesPav, stringUzduotiesJDL, stringKitiFailai; 

Button holder; 
private ArrayList<Item> m_parts = new ArrayList<Item>(); 
private Runnable viewParts; 
private ItemAdapter m_adapter; 

private final String data[] = { "Android", "iPhone", "BlackBerry", "AndroidPeople" }; 
private final String data2[] = { "Ivykdyta", "Atsaukta", "Einama", "Nusisnekejo" }; 
List<String> a = new ArrayList<String>(); 
List<String> b = new ArrayList<String>(); 


public static void setDefaults(String key, String value, Context context) { 
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context); 
    SharedPreferences.Editor editor = prefs.edit(); 
    editor.putString(key, value); 
    editor.commit(); 
} 
public static String getDefaults(String key, Context context) { 
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context); 
    return preferences.getString(key, null); 
} 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    this.setContentView(R.layout.activity_busena); 
    this.setTheme(R.style.listItem); 
    holder = (Button)findViewById(R.id.button19); 



    proxyGaliojimas = (TextView)findViewById(R.id.generatenumber); 
    proxySuteike = (TextView) findViewById(R.id.textView5); 

    randomInt = Integer.parseInt(getDefaults("proxy", this)); 
    stringProxySuteike = getDefaults("vo", this); 

    proxyGaliojimas.setText(randomInt + " min."); 
    proxySuteike.setText(stringProxySuteike); 

    stringUzduotiesPav = getDefaults("uzduotiesPav", this); 
    stringUzduotiesJDL = getDefaults("jdlFailoReiksme", this); 
    stringKitiFailai = getDefaults("kitiFailaiReiksme", this); 


    ListView list = (ListView)findViewById(R.id.tab1); 


    m_parts.add(new Item(stringUzduotiesPav, stringUzduotiesJDL)); 


    m_adapter = new ItemAdapter(this, R.layout.row, m_parts); 
    list.setAdapter(m_adapter); 

    button4 = (Button) findViewById(R.id.refreshProxy); 
    TabHost tabHost = getTabHost(); 
    this.setNewTab(this, tabHost, "tab1", R.string.uzduotys, android.R.drawable.star_on, R.id.tab1); 
    this.setNewTab(this, tabHost, "tab2", R.string.proxy, android.R.drawable.star_on, R.id.tab2); 

    addListenerOnButton(); 

} 


/*@Override 
protected void onListItemClick(ListView l, View v, int position, long id) { 
    String item = (String) getListAdapter().getItem(position); 
    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show(); 
}*/ 

private void setNewTab(Context context, TabHost tabHost, String tag, int title, int icon, int contentID) { 
    TabSpec tabSpec = tabHost.newTabSpec(tag); 
    String titleString = getString(title); 
    tabSpec.setIndicator(titleString, context.getResources().getDrawable(android.R.drawable.star_on)); 
    tabSpec.setContent(contentID); 
    tabHost.addTab(tabSpec); 
} 

public void addListenerOnButton() { 
    button4.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      int skaicius = randomInt; 
      Random randomGenerator = new Random(); 
      int rand = randomGenerator.nextInt(240-skaicius); 
      String ats = Integer.toString(randomInt); 
      proxyGaliojimas.setText(ats + " min."); 
      randomInt = rand; 
     } 

    }); 
} 
} 

这是我所看到的：

这是选项卡活动的XML文件：

请人给我简单例子或其他帮助:)

Answer 1

创建此方法： -

private static View createTabView(Context context, String tabText) { 
    View view = LayoutInflater.from(context).inflate(R.layout.custom_tab, null, false); 
    TextView tv = (TextView) view.findViewById(R.id.tabTitleText); 
    tv.setText(tabText); 
    return view; 
} 

---

在布局文件夹中创建custom_tab.xml文件

<?xml version="1.0" encoding="utf-8"?> 
<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
      android:id="@+id/tabTitleText" 
      android:layout_width="@dimen/tabWidth" 
      android:layout_height="wrap_content" 
      android:gravity="center_horizontal" 
      android:clickable="true" 
      android:paddingTop="@dimen/tabTopPading" 
      android:paddingBottom="@dimen/tabBottomPading" 
      android:paddingLeft="@dimen/tabLeftPading" 
      android:paddingRight="@dimen/tabRightPading" 
      android:textSize="@dimen/tabTextSize" 
      android:textColor="@color/themeColor" 
      android:background="@drawable/tab_selector"/> 

---

最后套装

tabHost.newTabSpec("Tab1").setIndicator(createTabView(getApplicationContext(),"Tab_name"))
