问题描述

我使用了自定义 ListView,并且我正在使用相同的 ListView 显示一些数据.

当我点击列表视图项时,onClickListener 没有被调用.我无法选择任何列表项.

I have used a Custom ListView and I am displaying some data using the same ListView.

When I click on the List View item, the onClickListener is not getting called. I am not able to select any list item.

布局代码:

<?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>

适配器代码:

 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;
}

}

ListView 代码:

 ListView propertylistview = (ListView) findViewById(R.id.listview);
CustomListAdapter customlistview=new CustomListAdapter(PropertiesArray);
propertylistview.setAdapter(customlistview);

ListView XML:

 <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:

<?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>

即使滚动也不起作用.

我无法弄清楚为什么会发生这种情况?我错过了什么吗?

I am unable to figure out why is this happening? Am I missing out something?

对解决此问题的任何帮助表示赞赏.

Any help in resolving this is appreciated.

推荐答案

以下内容将适用于您的情况.

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();

            }
        };

不要忘记从 CustomAdapter 中删除以下内容

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();
    }
});
