我想最初在列表视图中隐藏编辑文本和按钮字段,并在单击该原始文件时在列表视图中显示特定原始文件的编辑文本和按钮。所以我尝试在布局 xml 中将高度设置为 0,然后设置它当用户单击原始数据时,将其更改为其他值,但它不起作用我认为我的列表视图单击事件不起作用。在我有列表视图的 Android 布局中,有图像视图作为按钮,也可以编辑文本字段和列表视图。如下

<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>

我为列表视图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" />

这里我贴出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。提前致谢。

将以下属性添加到您的按钮

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

ListView setOnItemClickListener 通过添加按钮不起作用

您的 edittext 是否专注于单击列表项?如果是这样,也请删除对 edittext 的关注。

这里列表视图中的编辑文本具有所有焦点,因此此列表视图 onClick 不起作用。从editext框中删除焦点,它将开始工作

// 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();
            }
        });
    }
}

在我的情况下,setOnItemClickListener 在 Android 版本高达 5.1.1 但在 Android 6.0.1 上运行良好。最后我找到了解决方案试试这个
从你的 XML 布局中删除这些行

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

适用于我的 Android 版本 6.0.1 希望您的问题得到解决..!!! 快乐编码:)
