android - 如何遍历android中 ListView 每一行中的每个复选框？

Question

我有一个应用程序，在 ListView 的每一行中包含三个 TextView 和一个复选框。我希望通过单击按钮，我将能够获取每个复选框的状态以及与 (isChecked) 复选框对应的行被删除。还有一件事是我的复选框被硬编码在 xml 文件中。我搜索了很多，但找不到任何具体内容。提前谢谢。这是我的代码...

Answer 1

试试这个:

在 getView(...) 方法中...

 final CheckBox lChk = ((CheckBox) pConvertView.findViewById(R.id.myChkBoxID)); 
 private List<lisInfo> m_lisInfo = new ArrayList<lisInfo>();

 lChk.setOnCheckedChangeListener(new OnCheckedChangeListener() {
     @Override
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
     // Populate the listInfo with check box status
     m_lisInfo.get(lPosition).setChkBoxStatus((isChecked));
  }
 });


 public class lisInfo{
   private boolean chkBoxStatus;

   public boolean isChkBoxStatus() {
        return chkBoxStatus;
    }

    public void setChkBoxStatus(boolean chkBoxStatus) {
        this.chkBoxStatus = chkBoxStatus;
    }
}

现在迭代listInfo，只要需要就可以获取 ListView 中的复选框状态
