我在我的应用程序中使用 tabhost。我们可以为每个选项卡提供单独的宽度属性吗？即，一个宽度较大，另一个宽度较小？请给我示例示例。如果可能的话，请给我代码。

编辑： 

public class TabBarSimple extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.main);



    TabHost tabHost = getTabHost();
    TabHost.TabSpec spec;
    Intent intent;

    TabSpec dbspec = tabHost.newTabSpec("DashBoard");
    dbspec.setIndicator("Dashboard", getResources().getDrawable(R.drawable.dashboard));

    Intent dbIntent = new Intent(this, PhotosActivity.class);
    dbspec.setContent(dbIntent);
    tabHost.addTab(dbspec);

    TabSpec orderspec = tabHost.newTabSpec("Orders");
    orderspec.setIndicator("Orders", getResources().getDrawable(R.drawable.orders));

    Intent orderIntent = new Intent(this, SongsActivity.class);
    orderspec.setContent(orderIntent);
    tabHost.addTab(orderspec);
    TabSpec settingspec = tabHost.newTabSpec("Customers");
    settingspec.setIndicator("Customers", getResources().getDrawable(R.drawable.customers));
    Intent settingIntent = new Intent(this, VideosActivity.class);
    settingspec.setContent(settingIntent);
    tabHost.addTab(settingspec);
    TabSpec aboutspec = tabHost.newTabSpec("Settings");
    aboutspec.setIndicator("Settings", getResources().getDrawable(R.drawable.settings));
    Intent aboutIntent = new Intent(this, PhotosActivity.class);
    aboutspec.setContent(aboutIntent);
    tabHost.addTab(aboutspec);
    TabSpec logoutspec = tabHost.newTabSpec("Logout");
    logoutspec.setIndicator("Logout", getResources().getDrawable(R.drawable.logout));
    Intent logoutIntent = new Intent(this, SongsActivity.class);
    logoutspec.setContent(logoutIntent);
    tabHost.addTab(logoutspec);


    for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
    {
    //tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#8A4117"));
    tabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.tab_indicator);
    tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 100;
    tabHost.getTabWidget().getChildAt(1).getLayoutParams().width = 50;
    }
    tabHost.getTabWidget().setCurrentTab(0);
    //tabHost.getTabWidget().getChildAt(0).setBackgroundColor(Color.parseColor("#C35817"));
    tabHost.getTabWidget().getChildAt(0).setBackgroundResource(R.drawable.tab_indicator);

     }

    public void onTabChanged(String tabId) {
          TabHost tabHost = getTabHost();
    // TODO Auto-generated method stub
    for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
    {
    //tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#8A4117"));
    tabHost.getTabWidget().getChildAt(i).setBackgroundResource(R.drawable.tab_indicator);
    }
    //tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#C35817"));
    tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundResource(R.drawable.tab_indicator);
    }

     }

您可以通过以下代码实现这一点 - ：

tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 50;
