Question

我想在列表视图中隐藏编辑文本和按钮字段，并在单击原始视图时显示特定原始列表视图中的编辑文本和按钮。所以我尝试在布局xml中将高度设置为0然后当用户点击原始时将其设置为其他值，但它不起作用我认为我的列表视图点击事件不起作用。在我有列表视图的Android布局中，还有图像视图作为按钮，编辑文本字段和列表视图。如下所示

<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>

我在列表视图中使用了以下自定义布局

<?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" />

这里我发布了Activity.java的代码。

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;
    }
}
}

上面我发布了一些我认为重要的代码。任何人都可以帮我完成这项任务。提前谢谢。

Answer 1

将以下属性添加到按钮

  android:focusable="false"
  android:focusableInTouchMode="false"

ListView setOnItemClickListener not working by adding button

您的编辑文字是否专注于点击列表项？如果是这样，也要删除对edittext的关注。

Answer 2

这里listview中的edittext具有所有焦点，因此这个listview onClick不起作用。从editext框中删除焦点，它将开始工作

Answer 3

// try this
public class MainPortal extends Activity {
    private List<Employee> employees = new ArrayList<Employee>();
    EditText et;
    ListView list;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_portal);
        populateEmployeeList();
        //populsteListView();

        list = (ListView) findViewById(R.id.employeeListView);
        ArrayAdapter<Employee> adapter = new MylistAdapter();
        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();
            }
        });
    }
}

Answer 4

在我的案例中，setOnItemClickListener在Android版本Upto 5.1.1中正常工作但拥有Android 6.0.1。最后我找到了解决方案试试这个从XML布局中删除这些行

android:orientation="vertical"
tools:context=".ManageRequest"
android:contextClickable="true"

在Android版本6.0.1中为我工作希望你的问题得到解决.. !!!快乐编码：）
