Question

我创建了一个listview应用程序然后我决定为listview设计页眉和页脚我的问题是我的页眉和页脚在后台显示我的列表视图。我希望隐藏这个页眉和页脚列表视图项目，以帮助我隐藏？

代码：

public class Settings extends Activity { 
    private SettingsAdapter setAdap;
    private SettingsInnerAdapter setInnerAdap;
    private ListView lstView;
    int top;
    private int mSelPosition = 0;
    private boolean innerListView = false;

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

        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
        WindowManager.LayoutParams.FLAG_FULLSCREEN); 

        setContentView(R.layout.testing);
        int width = getWindowManager().getDefaultDisplay().getWidth();
        int height = getWindowManager().getDefaultDisplay().getHeight();

        ImageView imgHead = (ImageView)findViewById(R.id.imageView1);

        ImageView imgbottom = (ImageView)findViewById(R.id.imageView2);


        imgbottom.setImageResource(R.drawable.back);
        imgbottom.setLayoutParams(new RelativeLayout.LayoutParams(width/8, height/8));


        imgHead.setImageResource(R.drawable.b);
        imgHead.setLayoutParams(new RelativeLayout.LayoutParams(width/8, height/8));

        setAdap = new SettingsAdapter(this.getApplicationContext());
        setAdap.updateImageSize(width, height);
        setAdap.setTextVisible(0);
       setAdap.setInnerViewVisible(false);


        lstView = (ListView)findViewById(R.id.lstLeft);
    lstView.setScreenDimension(width/16, height / 4 , width, height / 2);
        lstView.setAdapter(setAdap);
        lstView.setSelected(false);

      }

xml代码：

</RelativeLayout>

Answer 1

为您的Header View Layout和Footer View Layout提供ID，然后为ListView's

设置这些属性

<ListView
    android:id="@+id/lstRight"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_below="@+id/headerViewId"
    android:layout_above="@+id/footerViewId"
    android:cacheColorHint="#00000000" >
</ListView>

如何在我的页眉和页脚布局设计中隐藏背景列表视图？
