android - android中的自定义tabview

Question

我想设计一个只显示一个选项卡的页面。但是当我只添加一个选项卡时，它占用了可用的全部宽度，但我希望该选项卡只占用很小的空间并且剩余空间留空。我不想添加其他选项卡。始终只显示一个选项卡。代码如下

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

        TabHost tabHost = getTabHost();  // The activity TabHost
        TabHost.TabSpec spec;  // Resusable TabSpec for each tab
        Intent intent;  // Reusable Intent for each tab

        // Create an Intent to launch an Activity for the tab (to be reused)
        intent = new Intent().setClass(this, FirstTab.class);
        // Initialize a TabSpec for each tab and add it to the TabHost

        spec = tabHost.newTabSpec("firstTab").setIndicator("First Tab")
                      .setContent(intent);


        tabHost.addTab(spec);
        tabHost.setCurrentTab(1);

Answer 1

使用tabHost.getTabWidget().getChildAt(0).getLayoutParams().width =(int) 30;同时设置layout_width="wrap_content"
