Question

嗨请帮忙实际上我试图使列表视图不可见但它同时显示listview和gridview请帮助解决它。这是代码。

public void onCreate(Bundle icicle) { 
        super.onCreate(icicle); 
        setContentView(R.layout.main); 
        Gallery gallery = (Gallery) findViewById(R.id.gallery1);
     lst=(ListView)findViewById(R.id.list);
     lst.setVisibility(View.INVISIBLE);
   //  ViewManager hi=(ViewManager)getBaseContext().getSystemService(WINDOW_SERVICE );


        gallery.setAdapter(new ImageAdapter(this));        
        final GridView gridView = (GridView) findViewById(R.id.gridview);

        mInflater = (LayoutInflater) getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        data = new Vector<RowData>();
        for(int i=0;i<title.length;i++){
        try {
            rd = new RowData(i,title[i],detail[i]);
            } catch (ParseException e) {
                e.printStackTrace();
           }
           data.add(rd);
           lst.setAdapter(new CustomAdapter(this, R.layout.list,R.id.title,data));
        }

        gridView.setAdapter(new ImageAd(this));

        final TabHost tabs=(TabHost)findViewById(R.id.tabhost); 


        tabs.setup(); 

        final TabHost.TabSpec spec=tabs.newTabSpec("buttontab"); 
        final TabHost.TabSpec spec1=tabs.newTabSpec("btn"); 
        spec.setContent(R.id.list);
        lst.setVisibility(View.INVISIBLE);
        spec1.setContent(R.id.buttontab);
        spec.setIndicator("tab1");

        spec1.setIndicator("tab1");
        tabs.addTab(spec); 
        tabs.setCurrentTab(0); 
        tabs.getTabWidget().getChildAt(0).setLayoutParams(new
                LinearLayout.LayoutParams(30,30));
spec.setIndicator("tab2");
        tabs.addTab(spec);
        tabs.getTabWidget().getChildAt(1).setLayoutParams(new
                LinearLayout.LayoutParams(30,30));
        tabs.setOnTabChangedListener(new OnTabChangeListener(){
            @Override
            public void onTabChanged(String tabId) {
                if(tabId=="buttontab")

这是xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"

    >
    <LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="50px"

    <TextView

    />
    <EditText

    android:layout_width="100px"
    android:layout_height="wrap_content"
    />
    </LinearLayout>
     <Gallery
        android:id="@+id/gallery1"
        android:layout_width="fill_parent"

   <TabHost android:id="@+id/tabhost" 
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent">

        <FrameLayout android:id="@android:id/tabcontent" 
            android:layout_width="fill_parent" 
            android:layout_height="fill_parent"

            <ListView android:id="@+id/list"

         <GridView xmlns:android="http://schemas.android.com/apk/res/android"

    android:columnWidth="60dp"
    android:stretchMode="columnWidth"
    android:gravity="center"

</LinearLayout>
          </LinearLayout>>
        </FrameLayout> 
    </TabHost>

所以请帮助制作listview，因为invisiblei知道它的一个小错误但无法解决错误

Answer 1

尝试使用View.GONE而不是View.INVISIBLE

由于您在onCreate中执行此操作，因此您可以在XML中执行此操作：

 <ListView 
    android:id="@+id/list"
    android:layout_width="fill_parent" 
    android:layout_height="200px" 
    android:visibility="gone"
 />

创建视图
