我需要一些帮助来使用当前片段的代码设置背景颜色。该片段是在选择特定选项卡时创建的。

以下是我的主要活动代码

public class TabActionBarActivity extends Activity { 
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);        

    // Set the text and background colour
    setTheme(R.style.MyTheme);
    ActionBar actionBar = getActionBar();



    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);



    String label6 = getResources().getString(R.string.label6);
    tab = actionBar.newTab();
    tab.setText(label6);
    TabListener<Tab6Fragment> tl6 = new TabListener<Tab6Fragment>(this,
            label6, Tab6Fragment.class);
    tab.setTabListener(tl6);
    actionBar.addTab(tab);

    String label7 = getResources().getString(R.string.label7);
    tab = actionBar.newTab();
    tab.setText(label7);
    TabListener<Tab7Fragment> tl7 = new TabListener<Tab7Fragment>(this,
            label7, Tab7Fragment.class);
    tab.setTabListener(tl7);
    actionBar.addTab(tab);        


}

现在 Tab7Fragment 类的代码如下所示

    public class Tab7Fragment extends Fragment {

   TextView tv1;

   @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {        

        ScrollView sv = new ScrollView(this.getActivity());

        LinearLayout ll = new LinearLayout(this.getActivity());
        ll.setOrientation(LinearLayout.VERTICAL);
        sv.addView(ll);

        TextView tv = new TextView(this.getActivity());
        tv.setText("Dynamic layouts ftw!");
        ll.addView(tv);

        EditText et = new EditText(this.getActivity());
        et.setText("weeeeeeeeeee~!");
        ll.addView(et);

        Button b = new Button(this.getActivity());
        b.setText("I don't do anything, but I was added dynamically. :)");
        ll.addView(b);

        for(int i = 0; i < 20; i++) {
            CheckBox cb = new CheckBox(this.getActivity());
            cb.setText("I'm dynamic!");
            ll.addView(cb);
        }
        return this.getView();
    }

}

现在我该如何设置这个片段的视图？

this.getActivity().setContentView(sv);

我知道上面的方法是不正确的。但我需要使用滚动视图布局设置内容视图。另一个问题是我如何设置这个视图的背景颜色？（使用 setBackgroundColor()?

To set background color :

sv.setBackgroundColor(getRessources().getColors(R.color.yourcolor));

To inflate layout into a fragment, you need to return a View from onCreateView :

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle  savedInstanceState)     {
    return inflater.inflate(R.layout.your layout, container, false);
 }

在您的 onCreateView() 中尝试此代码：

View view = inflater.inflate(R.layout.your_fragment_layout, container, false);

然后不要忘记将刚刚膨胀的视图返回到 android 运行时。

删除return this.getView();和添加return view;
