You can set the onClickevent in your custom adapter's getViewmethod..

您可以onClick在自定义适配器的getView方法中设置事件..

In Adapter Class

在适配器类中

public View getView(final int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = getLayoutInflater();
    View row = inflater.inflate(R.layout.vehicals_details_row, parent, false);
    Button deleteImageView = (Button) row.findViewById(R.id.DeleteImageView);
    deleteImageView.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            //...
        }
    });
}

But you can get an issue - listView row not clickable. Solution:

但是您可能会遇到一个问题 - listView 行不可点击。解决方案：

• make ListView focusable android:focusable="true"
• Button not focusable android:focusable="false"

• 使 ListView 成为焦点 android:focusable="true"
• 按钮不可聚焦 android:focusable="false"

Try This,

尝试这个，

public View getView(final int position, View convertView,ViewGroup parent) 
{
   if(convertView == null)
   {
        LayoutInflater inflater = getLayoutInflater();
        convertView  = (LinearLayout)inflater.inflate(R.layout.YOUR_LAYOUT, null);
   }

   Button Button1= (Button)  convertView  .findViewById(R.id.BUTTON1_ID);

   Button1.setOnClickListener(new OnClickListener() 
   { 
       @Override
       public void onClick(View v) 
       {
           // Your code that you want to execute on this button click
       }

   });


   return convertView ;
}

It may help you....

In your custom adapter inside getView method :

在 getView 方法中的自定义适配器中：

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // Do things Here 
    }
});

回答by Paresh Mayani

I assume you have defined custom adapter for your ListView.

我假设您已经为 ListView 定义了自定义适配器。

If this is the case then you can assign onClickListenerfor your button inside the custom adapter's getView()method.

如果是这种情况，那么您可以onClickListener在自定义适配器的getView()方法中为您的按钮分配。

This has been discussed in many posts but still I could not figure out a solution with:

这已经在许多帖子中讨论过，但我仍然无法找到解决方案：

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

Below solution will work with any of the ui components : Button, ImageButtons, ImageView, Textview. LinearLayout, RelativeLayout clicks inside a listview cell and also will respond to onItemClick:

以下解决方案适用于任何 ui 组件：Button、ImageButtons、ImageView、Textview。LinearLayout、RelativeLayout 在列表视图单元格内单击，也会响应 onItemClick：

Adapter class - getview():

适配器类 - getview():

    @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View view = convertView;
            if (view == null) {
                view = lInflater.inflate(R.layout.my_ref_row, parent, false);
            }
            final Organization currentOrg = organizationlist.get(position).getOrganization();

            TextView name = (TextView) view.findViewById(R.id.name);
            Button btn = (Button) view.findViewById(R.id.btn_check);
            btn.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    context.doSelection(currentOrg);

                }
            });

       if(currentOrg.isSelected()){
            btn.setBackgroundResource(R.drawable.sub_search_tick);
        }else{
            btn.setBackgroundResource(R.drawable.sub_search_tick_box);
        }

    }

In this was you can get the button clicked object to the activity. (Specially when you want the button to act as a check box with selected and non-selected states):

在这里，您可以将按钮单击对象添加到活动中。（特别是当您希望按钮充当具有选中和未选中状态的复选框时）：

    public void doSelection(Organization currentOrg) {
        Log.e("Btn clicked ", currentOrg.getOrgName());
        if (currentOrg.isSelected() == false) {
            currentOrg.setSelected(true);
        } else {
            currentOrg.setSelected(false);
        }
        adapter.notifyDataSetChanged();

    }

I find

我发现

final Button yourButton = (Button)view.findViewById(R.id.your_button);
yourButton.setFocusable(false);
yourButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        ...///);

can solve the problem. If you want to get some data when clicking the button, using tags is helpful. Here the button is declared final because it will be used within inner class.

可以解决问题。如果您想在单击按钮时获取一些数据，使用标签会很有帮助。这里的按钮被声明为 final，因为它将在内部类中使用。

FOR KOTLIN USERS

对于 Kotlin 用户

inside your getView(...) method if you try to start an activity through button onClickListener:

如果您尝试通过按钮 onClickListener 启动活动，则在您的 getView(...) 方法中：

   myButton.setOnClickListener{
        val intent = Intent(this@CurrentActivity, SecondActivity::class.java)
        startActivity(intent)
   }

Pass the correct pointer for "this"

为“this”传递正确的指针
