我正在创建一个自定义适配器，以便可以在 listView 中放置一个按钮。我把它放进去，就像我放一张图片一样，然后我在教程中找到了这行代码：
button.setImageResource(current_item.getButton_id());
我尝试将其更改为setButtonResource，但没有方法。谢谢你的帮助。我希望它看起来像这样，其中有一个带有文本视图和按钮的列表视图。我把文本放得很好，但我不知道如何在列表视图中获得一个按钮。
这是我的适配器：
private class MyListAdapter extends ArrayAdapter<SchoolsListClass>{
public MyListAdapter() {
super(searchResults.this, R.layout.da_item, mySchools);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
//Make sure we have a view to work with (may have been given null
View itemView = convertView;
if (itemView == null){
itemView = getLayoutInflater().inflate(R.layout.da_item, parent, false);
}
//Find school to work with
SchoolsListClass currentSchoolsListClass = mySchools.get(position);
//Fill the view
//school name
TextView schoolText = (TextView) itemView.findViewById(R.id.item_schoolName);
schoolText.setText(currentSchoolsListClass.getSchool_name());
//subscribe/unsubscribe button
Button button = (Button)itemView.findViewById(R.id.item_subscribeButton);
button..setImageResource(currentSchoolsListClass.getButton_id());//This is the line of code I am having trouble with. I want it to do exactly what it is doing for images, but use buttons instead of images.
return itemView;
}
学校列表类：
package com.parse.starter;
public class SchoolsListClass {
private String school_name;
private int button_id;
public SchoolsListClass(String school, int button){
super();
this.school_name = school;
this.button_id = button;
}
public String getSchool_name() {
return school_name;
}
public int getButton_id() {
return button_id;
}
}
school_results.xml：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/listMain"
android:layout_width="match_parent"
