Android的列表视图setOnItemClickListener不工作 [英] Android list view setOnItemClickListener not working
问题描述
我想隐藏最初在列表视图中编辑的文本和按钮字段，并显示在列表视图中的特定原始的编辑文本和按钮时生吃clicked.So我试过的高度设置为0的布局xml和然后将其设置为其他值，当用户点击一个原始的，但它不工作，我想我的列表视图中单击事件无法正常工作。 在Android的布局，我有列表视图中有图片视图按钮，编辑文本框和列表视图还。就像如下
I want to hide the edit text and button field initially in list view and show that edit text and button for a particular raw in list view when that raw is clicked.So I tried to set the height to 0 in layout xml and then set it to some other value when user clicks on a raw, but it is not working I think my list view click event is not working. In the Android layout that I have list view there are Image view as a button, edit text field and list view also. Like follows
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainPortal" >
<ListView
android:id="@+id/employeeListView"
android:layout_width="650dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="25dp"
android:clickable="true">
</ListView>
<EditText
android:id="@+id/empPin"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/iv_start_journey_btn"
android:layout_marginBottom="56dp"
android:layout_marginRight="17dp"
android:layout_toLeftOf="@+id/employeeListView"
android:ems="10"
android:inputType="number"
android:hint="@string/add_emp_pin_hint" >
<requestFocus />
</EditText>
<ImageView
android:id="@+id/iv_start_journey_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/employeeListView"
android:layout_alignRight="@+id/empPin"
android:layout_marginBottom="84dp"
android:onClick="startJourney"
android:src="@drawable/start" />
</RelativeLayout>
我已经使用下面的自定义布局列表视图
I have used following custom lay out for the list view
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/emp_avatar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="18dp"
android:adjustViewBounds="true"
android:maxHeight="80dp"
android:maxWidth="80dp"
android:src="@drawable/person" />
<TextView
android:id="@+id/emp_number"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@+id/emp_avatar"
android:layout_toRightOf="@+id/emp_avatar"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText
android:id="@+id/empPin"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_alignBottom="@+id/emp_avatar"
android:layout_alignRight="@+id/emp_number"
android:layout_toRightOf="@+id/emp_avatar"
android:ems="10"
android:inputType="number" >
<requestFocus />
</EditText>
<Button
android:id="@+id/empAdd"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_alignBaseline="@+id/empPin"
android:layout_alignBottom="@+id/empPin"
android:layout_marginLeft="20dp"
android:layout_toRightOf="@+id/empPin"
android:text="@string/emp_add_btn" />
下面我发布Activity.java的code。
Here I post the code of Activity.java.
public class MainPortal extends Activity {
private List<Employee> employees = new ArrayList<Employee>();
EditText et;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_portal);
populateEmployeeList();
//populsteListView();
ListView list = (ListView) findViewById(R.id.employeeListView);
ArrayAdapter<Employee> adapter = new MylistAdapter();
list = (ListView) findViewById(R.id.employeeListView);
list.setAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
//I ADDED ON CLICK IMPLEMENTATION HERE, BUT THIS IS NOT WORKING
Toast.makeText(getApplicationContext(), "CLICKED", Toast.LENGTH_SHORT).show();
}
});
private void populateEmployeeList() {
...
}
private class MylistAdapter extends ArrayAdapter<Employee>{
public MylistAdapter(){
super(MainPortal.this,R.layout.item_view,employees);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View itemView = convertView;
if(itemView==null){
itemView = getLayoutInflater().inflate(R.layout.item_view, parent,false);
}
Employee currentEmployee = employees.get(position);
//Avatar
ImageView imageView = (ImageView) itemView.findViewById(R.id.emp_avatar);
imageView.setImageResource(currentEmployee.getAvatarId());
//Employee number
TextView emp_id = (TextView) itemView.findViewById(R.id.emp_number);
emp_id.setText(currentEmployee.getId());
et = (EditText) itemView.findViewById(R.id.empPin);
return itemView;
}
}
}
上面我已经发布了一些codeS，我认为很重要的。 任何一个可以请帮我做这个任务。 先谢谢了。
Above I have posted some codes that I think important. Can any one please help me to do this task. Thanks in advance.
推荐答案
添加以下属性到您的按钮
Add the following attributes to your button
android:focusable="false"
android:focusableInTouchMode="false"
<一个href="http://stackoverflow.com/questions/6703390/listview-setonitemclicklistener-not-working-by-adding-button">ListView setOnItemClickListener工作不加入按钮
是您的EditText采取注重点击列表项的？如果是这样去除的EditText也是关注的焦点。
Is your edittext taking focus on click of list item? If so remove the focus on edittext also.
