具有自定义行的 Android 适配器，与活动列表视图进行通信

发布于 2024-12-05 10:53:02 字数 824 浏览 0 评论 0原文

我有一个带有列表视图的活动。

在 listview 的底部，我有一个“所选项目”textview 和一个保存按钮。列表视图使用具有多个文本字段和单选按钮的适配器。我了解如何为适配器中的单选按钮添加单击事件。我需要知道如何获取适配器中的点击事件以更新 textview 中的“所选项目”。

添加代码

listView1.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    PlanListObj pl = planAdapter.getItem(position);
    switch (view.getId()) {
        case R.id.radioButton1:
    selection.setText("Radio: " + pl.getPlanName());
    break;
        default:
    selection.setText("Row: " + pl.getPlanName());
    }
     }
});

如果我单击自定义行上的单选按钮，则 R.id.radioButton1 情况无效，大概是因为单选按钮正在发送 onClick ，而不是 OnItemClick。

预先感谢

I have an activity with a listview.

At the bottom of the listview I have a 'Selected item' textview and a save button.
the list view uses an adapter with multiple text fields and a radio button.
I understand how to add click events for the radio buttons in the adapter.
I need to know how to get the click events in the adapter to update the 'Selected item' in the textview.

Code Added

listView1.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    PlanListObj pl = planAdapter.getItem(position);
    switch (view.getId()) {
        case R.id.radioButton1:
    selection.setText("Radio: " + pl.getPlanName());
    break;
        default:
    selection.setText("Row: " + pl.getPlanName());
    }
     }
});

If I click the radio button on the custom row the R.id.radioButton1 case is not valid, presumably as the radio button is sending an onClick, not an OnItemClick.

Thanks in advance

首先，我希望您开始接受答案:)

这很简单，因为您可以在主要活动中使用：

yourListView.setOnItemClickListener(new OnItemClickListener(){
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        //here you can update the textview and get the selected value from the view or position
    }
});

First I hope you start accepting answers :)

This is simple because you can use in your main activity:

yourListView.setOnItemClickListener(new OnItemClickListener(){
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        //here you can update the textview and get the selected value from the view or position
    }
});
