【问题描述】:
我有一个自定义列表视图。主要布局xml是这样的:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView android:layout_height="wrap_content"
android:id="@+id/lv_clientes"
android:layout_width="0dp">
</ListView>
<!-- From this part there are not problems -->
</LinearLayout>
列表项 XML 是这个
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rlo_elemento"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView android:id="@+id/tv_nombre"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<!-- From this part there are not problems -->
</RelativeLayout>
现在适配器是这样的:
public class AdapterListaClientes extends BaseAdapter
{
private Cliente[] data;
Context context;
LayoutInflater layoutInflater;
int itemSelected = -1;
public void setSelected(int valor)
{
itemSelected = valor;
}
public AdapterListaClientes(Context context, ArrayList<Cliente> data)
{
this.data = data.toArray(new Cliente[0]);
this.context = context;
layoutInflater = LayoutInflater.from(context);
}
/*Mandatory things and so...*/
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
//All the things that we should put in this point.. I'm using the list14 example
//HERE IS THE POLEMIC CODE
if(position == itemSelected)
convertView.setBackgroundColor(R.color.rojo);
else
convertView.setBackgroundColor(R.color.blanco);
return convertView;
} }
setBackgroundColor() 方法不起作用。我知道这是在做某事,因为当我使用此方法时,按下列表视图项目时,按下项目的背景颜色会变为默认颜色的不透明版本。
这个问题只发生在背景颜色上,我可以毫无问题地更改其他所有内容...
谢谢!
