问题描述
我用了一个自定义ListView和使用ListView控件显示的一些数据。当我点击列表视图项目时,onClickListener在不触发。我无法选择任何列表项。
I used a Custom ListView and displayed some data using that ListView. When I click on the List View item, the onClickListener is not firing. I was not able to select any list item.
XML code,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginBottom="16dp"
android:background="@drawable/list_selector"
android:clickable="true"
android:orientation="horizontal"
android:padding="5dip" >
<LinearLayout
android:id="@+id/imgProperty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginRight="5dip"
android:padding="3dip" >
<ImageView
android:id="@+id/list_image"
android:layout_width="50dp"
android:layout_height="50dp"
android:contentDescription="@string/app_name"
android:src="@drawable/ic_launcher"
android:focusable="false"/>
</LinearLayout>
<TextView
android:id="@+id/tvCity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="75dip"
android:layout_toRightOf="@+id/list_image"
android:paddingBottom="10dip"
android:text="property"
android:textColor="#040404"
android:textSize="15sp"
android:textStyle="bold"
android:typeface="sans" />
<TextView
android:id="@+id/tvprice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/imgProperty"
android:layout_alignLeft="@+id/tvCity"
android:text="Price"
android:focusable="false"/>
</RelativeLayout>
自定义列表视图类,
custom list view class,
public class CustomListAdapter extends BaseAdapter {
ArrayList<Propety> PropertiesArray;
private LayoutInflater Inflater;
public CustomListAdapter(ArrayList<Propety> PropertiesArray) {
this.PropertiesArray=PropertiesArray;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return PropertiesArray.size();
}
@Override
public Object getItem(int position) {
return PropertiesArray.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, final ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(parent.getContext());
convertView = inflater.inflate(R.layout.customlistview, parent, false);
}
final Propety ListArray = PropertiesArray.get(position);
TextView tvPropertyName = (TextView) convertView.findViewById(R.id.tvCity);
tvPropertyName.setText(ListArray.getName());
TextView tvPrice = (TextView) convertView.findViewById(R.id.tvprice);
tvPrice.setText(ListArray.getPrice());
ImageView imgProperty = (ImageView) convertView.findViewById(R.id.list_image);
imgProperty.setImageResource(R.drawable.ic_launcher);
convertView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(parent.getContext(), "view clicked: " + ListArray.getName(), Toast.LENGTH_SHORT).show();
}
});
return convertView;
}
}
的ListView code,
ListView code,
ListView propertylistview = (ListView) findViewById(R.id.listview);
CustomListAdapter customlistview=new CustomListAdapter(PropertiesArray);
propertylistview.setAdapter(customlistview);
和XML的ListView控件,
and the xml for ListView,
<ListView
android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/customview"
android:layout_marginBottom="10dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="24dp"
android:background="@drawable/list_selector"
android:textAlignment="center" >
custom.xml,
custom.xml,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<SurfaceView
android:id="@+id/surface"
android:layout_width="fill_parent"
android:layout_height="match_parent" />
<TextView
android:id="@+id/txtangle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_marginBottom="115dp"
android:layout_marginLeft="95dp"
android:text="" />
<ListView
android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/customview"
android:layout_marginBottom="10dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="24dp"
android:background="@drawable/list_selector"
android:textAlignment="center" >
</ListView>
<view
android:id="@+id/customview"
android:layout_width="110dp"
android:layout_height="110dp"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
class="com.example.samplebuapp.CustomCompass" />
<view
android:id="@+id/view1"
android:layout_width="110dp"
android:layout_height="110dp"
android:layout_above="@+id/listview"
android:layout_alignParentRight="true"
android:layout_marginRight="18dp"
class="com.example.samplebuapp.CustomView" />
<LinearLayout
android:id="@+id/rl1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/listview"
android:orientation="vertical"
android:focusable="false">
</LinearLayout>
</RelativeLayout>

推荐答案
下面将做的工作在你的案件。
The following will do the job in your case.
ListView propertylistview = (ListView) findViewById(R.id.listview);
propertylistview.setOnItemClickListener( myListViewClicked ):
OnItemClickListener myListViewClicked = new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(YourActivity.this, "Clicked at positon = " + position, Toast.LENGTH_SHORT).show();
}
};
不要忘记删除该CustomAdapter以下
Dont forget to remove the following from the CustomAdapter
convertView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(parent.getContext(), "view clicked: " + ListArray.getName(), Toast.LENGTH_SHORT).show();
}
});
