Question

我实现了一个标签布局，其中包含四个标签，每个标签包含一个列表视图。我之前使用的是listview的相同设置但不在tab主机下，它运行正常，即;单击列表项时，将启动新活动。但是现在列表既不可点击也不可滚动。现在，当我单击所有选项卡一次然后尝试滚动/单击行时，它完全正常。请让我知道我如何启用这两个。代码如下

tabHost = (TabHost) findViewById(android.R.id.tabhost);
        tabHost.setup();
        tabHost.setOnTabChangedListener(this);

        list = (ListView) findViewById(R.id.listAll);
        list.setEmptyView((TextView) findViewById(R.id.empty));

        //list for all

        tabHost.addTab(tabHost.newTabSpec(LIST_ALL).setIndicator("All Events").setContent(new TabContentFactory() {
            public View createTabContent(String arg0) {
                try{
                    Event event = new Event();
                    final String [] eventTitleArray = new String[XmlParser.eventsList.size()];
                    String [] eventDateArray = new String[XmlParser.eventsList.size()];
                    String [] eventImageLinkArray = new String[XmlParser.eventsList.size()];

                for(int i=0;i<XmlParser.eventsList.size();i++){
                        event = XmlParser.eventsList.get(i);
                        eventTitleArray[i] = event.getTitle();
                        if(event.getDistance()!=0.0)
                            eventDateArray[i] = event.getsDate() +" - " +Double.toString(event.getDistance())+"mi";
                        else
                            eventDateArray[i] = event.getsDate();
                        eventImageLinkArray[i] = event.getImageLink();


                        Log.i(tag , "event detail"+event.getTitle());
                    }
                    list=(ListView)findViewById(R.id.listAll);
                    adapter= new LazyAdapter(HomeActivity.this, eventTitleArray,eventDateArray,eventImageLinkArray);
                    list.setAdapter(adapter);
                    list.setFocusable(false);
                    list.setOnItemClickListener(new OnItemClickListener() {
                        @Override
                        public void onItemClick(AdapterView<?> arg0, View arg1,
                                int position, long arg3) {
                            Intent intent = new Intent(HomeActivity.this, DisplayActivity.class);
                            Bundle b = new Bundle();
                            System.out.println("position in list:"+position);
                            System.out.println("title name in the list:"+eventTitleArray[position]);
                            b.putString("eventTitle", eventTitleArray[position]);
                            intent.putExtras(b);
                            startActivity(intent);

                            Toast.makeText(getApplicationContext(), "Detailed view for the Event", Toast.LENGTH_SHORT).show();


                        }
                    });
                }
                catch(Exception e){
                    e.printStackTrace();
                }
                return list;
            }
        }));

        tabHost.addTab(tabHost.newTabSpec(LIST_TODAY).setIndicator("Events Today").setContent(new TabContentFactory() {
            public View createTabContent(String arg0) {
                return list;
            }
        }));

您是否在Layout XML文件中将ListView标记为可点击？

看起来应该是这样的：

<ListView 
       android:id="@+id/MyListView" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content"
       android:clickable="true"/>

我刚刚做了这个，现在列表完全正常。

        tabHost.setCurrentTab(3);
        tabHost.setCurrentTab(2);
        tabHost.setCurrentTab(1);
        tabHost.setCurrentTab(0);
