改变列表视图ListView中的字体和背景

我想改变列表视图ListView中的字体(颜色和大小)和背景。我想用代码改变而不是想通过设置xml的属性实现。以下的list view看起来就像xml: <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:textSize="18sp" android:text="@string/hello"> 我的代码是： public class NewsActivity extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // ArrayAdapter listItemAdapter = new ArrayAdapter( this,android.R.layout.simple_list_item_1, v_itemList ); setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item,ynetList)); View v=getListView() ; ListView lv = getListView(); 接下来再写什么代码呢？

Android listview 随着item点击量进行排序 求大神给思路

1、listview中显示的是不同的商品，商品在本地的商品数据库中存储， 2、我在商品数据库中添加了一个字段：c_num 3、那个字段用于保存该商品的点击次数。 问题来了：我该如何根据点击次数大小进行listview的排序？ 从数据库取出来的商品列表为 List<ShangPinBean> zhanShiShangPinList 。 创建的adapter为：MyAdapter myAdapter。 listview为：ListView mListView。

Android关于改变ListView里面的ImageView控件的背景图出现无法触发点击事件的问题

问题说明：我使用AudioRecord进行录音，想要点击ImageView开始录音，然后根据音量大小设置ImageView背景图 ，由于ImageView是ListView的Item里面的一个子控件，于是我开启一个线程，使Thread.sleep(100);后 notifyDataSetChanged()，这时问题就出现了，当我再次点击ImageView想要录音暂停时，发现有时候点击事件无法触发，请问大神们，这是怎么回事，在线等待中。。。。。。希望大家帮帮忙。。。。。。

ListView中因layout_height是wrap_content而引发的问题

问题描述： 先是点击画面上的一个按钮，然后出现下方弹窗 图一：点击弹窗内的“show preview”，会出现listview，如图二  图二：listview出现之后，快速点击任意item，按照设计应该是出现图一的画面  但是实际上出现的是图三的画面， 图三：图中出现了和listview大小一样的透明层  这种现象只会在listview初始化的时候并且是快速点击下才会出现，往后怎么点击都不会出现。 现在怀疑这个问题可能是因为ListView中的layout_height是wrap_content而引发的问题，改成具体fill_parem或者是具体的高度就能够解决，但是要怎么证明这个现象是由这个问题导致的呢？ 代码如下： ``` <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/flipper_setting" android:layout_width="fill_parent" android:layout_height="400px" android:orientation="vertical" android:gravity="center_vertical" android:background="@color/gold" > <!-- setting category page --> <LinearLayout android:id="@+id/layout1" android:layout_width="fill_parent" android:layout_height="400px" android:gravity="top" android:orientation="vertical"> <!-- Preview Setting --> <include android:id="@+id/include_setting_preview" layout="@layout/list_row_setting_category" /> </LinearLayout> <!-- detail setting page --> <LinearLayout android:layout_width="fill_parent" android:layout_height="400px" android:gravity="top" android:orientation="vertical" android:id="@+id/layout2"> <TextView android:id="@+id/text_title_detail" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center_vertical" android:textSize = "20px"/> <com.example.viewflippertest.ListViewConfig android:id="@+id/listview_detail" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@color/white" /> </LinearLayout> </LinearLayout> ``` ``` public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

为何ListView中唯独不能设置字体颜色？

ListView需要用imageloader加载大量网络图片滑动卡顿

需求：类似QQ空间动态功能，每个Item加载头像跟图片还有一些文字。 使用的是UIL来加载图片。 问题：在滑动listview的时候会卡顿，然后加载过的图片再次出现的时候又会重新加载。并不能实现首次下载第二次的时候从内存中加载。PS：每张图片大小在20K以内、网络状态良好。 已尝试方法：优化ImageLoaderConfiguration、设置ListView.setOnScrollListener(new PauseOnScrollListener(imageLoader, true, true));、把UIL更新到最新的1.9.4。 我在网上查了很多，最多方法是给ImageView设置Tag，在加载完成时判断。if(imageUri.equals(holder.ivIcon.getTag())){ holder.ivIcon.setImageBitmap(loadedImage); } 但是我用的是imageloader.displayImage。 另外，如果给imageview加tag，然后用imageloader.loadimage（）来加载图片。在onLoadingComplete()中是不能判断imageview.tag是否等于imageUri的。因为我是在adpter中，用的holder，如果要可以用，就得吧holder定义为final，然而在holder = new ViewHolder();的时候就会让holder移除holder，互相矛盾。 求大神指导。万分感谢！ Adapter的getView()代码如下： @Override public View getView(int position, View convertView, ViewGroup parent) { IPetUserEvent userevent = (IPetUserEvent) getItem(position); IPetUserEventDao usereventdao=new IPetUserEventImpl(); IPetUser user=usereventdao.getUserById(userevent.getUserid()); String userName=user.getiName(); String userHeadPic=user.getiImg(); ViewHolder holder = null; if (convertView == null) { convertView = LayoutInflater.from(context).inflate(R.layout.item_userevent, null); holder = new ViewHolder(); holder.imgUserHeadPic=(ImageView) convertView.findViewById(R.id.img_item_userevent_head); holder.imgPic = (ImageView) convertView.findViewById(R.id.iv_item_userevent_eventpic); holder.tvTitle = (TextView) convertView.findViewById(R.id.tv_item_userevent_eventname); holder.tvTime = (TextView) convertView.findViewById(R.id.tv_item_userevent_eventtime); holder.tvUserName=(TextView) convertView.findViewById(R.id.tv_item_userevent_username); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.tvTitle.setText(userevent.getEventname()); holder.tvTime.setText("活动时间："+userevent.getEventtime()); holder.tvUserName.setText(userName); String url= HttpUtil.BASE_URL+"uploadfile/userevent/"+userevent.getEventpic(); String url1= HttpUtil.BASE_URL+"uploadfile/userImage/"+userHeadPic; imageLoader.displayImage(url1, holder.imgUserHeadPic, options, animateFirstListener); imageLoader.displayImage(url, holder.imgPic, options, animateFirstListener);// return convertView; }

android viewpage动态加载同一个布局轮播

根据网络获取数据的不同大小动态向viewpage加载同一个布局页面，就像listview的Item布局那样， 有textview image ，怎么实现啊？ 我的代码： for(int i=0;i<list.size();i++){ View v=lf.inflate(R.layout.doctor_item, null); viewListView.add(v); } 传给pageadapter 然后在instantiateItem中赋值 Textview v=viewList.get(position).findviewbyId(R.id.name_tv); v.setText("姓名") Textview a=viewList.get(position).findviewbyId(R.id.name_tv); a.setText("年龄") 这样可是最后结果 却不正确。 添加了两页 结果只有第一页显示数据。第二页是空的 求大神 帮忙实现
