【问题描述】：

在我的应用程序中，我将联系人导入列表视图，试图更改列表视图的背景颜色，我可以更改整个列表视图的颜色，但是，我希望仅更改具有地址和其余部分的联系人的颜色一样的。

  @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        View view = convertView;

        if (view == null) {

                if (position % 2 == 0)
                        view.setBackgroundResource(R.drawable.listshape);
                else
                        view.setBackgroundResource(R.drawable.favoritebody);
        return view;
    }

只有当我有联系人地址时如何更改颜色？

【问题讨论】：

这有帮助吗？ stackoverflow.com/q/4634796/1777090 。然后你可以设置一个条件来检查是否有任何细节！
如何查看列表行是否有关联地址？
对不起，你能把完整的 getView() 方法发给你吗
@nick..这是我的完整代码pastebin.com/D0eMR5x4
在 layout.setTag(contact); 之后立即添加if( !myContact.getAddress().isEmpty() ) { layout.setBackgroundColor(color) //or //layout.setBackgroundDrawable(background) }

标签： android android-listview

【解决方案1】：

替换下面的代码

 if (position % 2 == 0)
                        view.setBackgroundResource(R.drawable.listshape);
                else
                        view.setBackgroundResource(R.drawable.favoritebody);

由

if (!contact.getAddress().isEmpty() ){
    view.setBackgroundColor(R.drawable.hasaddress);
    }
else
{



     if (position % 2 == 0)
                            view.setBackgroundResource(R.drawable.listshape);
                    else
                            view.setBackgroundResource(R.drawable.favoritebody);
    }

【讨论】：

我应该在哪里添加代码？
在layout.setTag(contact);之后添加
我做了这个 layout.setTag(contact); if(!contact.getAddress().isEmpty()) { layout.setBackgroundColor(R.drawable.hasaddress); } 应用程序正在停止..itz 不工作
好的。使用视图而不是布局。你能告诉我为什么你使用这个代码 if (position % 2 == 0) view.setBackgroundResource(R.drawable.listshape); else view.setBackgroundResource(R.drawable.favoritebody);
使用：if(!myContact.getAddress().isEmpty()) view.setBackgroundColor(R.drawable.hasaddress) }

【解决方案2】：

使用这个getView

        view = inflater.inflate(renderer, null);
    }

    TextView text = (TextView) view.findViewById(R.id.name);
    ImageView photo = (ImageView) view.findViewById(R.id.photo);

    TextView textContNo = (TextView) view.findViewById(R.id.contactno);
    TextView textEmailId = (TextView) view.findViewById(R.id.emailId);

    Profile contact = listCont.get(position);
    text.setText(contact.getName());
    contact.getName();
    contact.getId();

    text.setTag(contact);
    text.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            Profile myContact= (Profile) v.getTag();

            Intent intent = new Intent();
            intent.putExtra("type", profileType);

【讨论】：

最后表示返回视图之前； ?
是的。返回视图之前；
但是大括号出现问题..itz 不允许...
你的整个 getView 应该看起来像新的答案
在 myContacts 出现错误...要求创建变量或字段

【解决方案3】：

如果您只想更改某些行的任何属性，您需要为各个行定义单独的布局，或者在 ListView 的 bindView() 方法中，更改您需要的属性。

【讨论】：

【解决方案4】：

您可以通过在 res 目录中添加一个颜色文件夹来实现此目的，并在颜色文件夹中为颜色定义一个 xml 并像下面这样定义并像 anyname.xml 一样保存它

    <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" 
        android:color="@color/whiteColor"></item>
    <item android:color="@color/bluetxt"></item> 
</selector>

并在显示信息的定义文本视图中提供此 xml 的引用

【解决方案5】：

在活动/片段中声明您自己的列表视图以及 SimpleAdapter

private ListView myListView;
private SimpleAdapter adapter;

从布局中找到您的列表视图

myListView = (ListView)v.findViewById(R.id.my_list_view);

像这样初始化你的适配器并将它绑定到你的列表视图

adapter = new SimpleAdapter(myListView.getContext(),
            my_profile_arrayList,
            R.layout.listview_layout_for_the_contact_with_different_color, new String[] { "type",
                    "name", "contactid" }, new int[] {
                    R.id.profile_type,
                    R.id.profile_name,
                    R.id.profile_contactid });

    myListView .setAdapter(adapter);

只需定义您自己的listview_layout_for_the_contact_with_different_color

我很困惑..你能看看我的代码并告诉我需要改变什么..
