我使用自定义适配器创建了一个列表视图，该适配器具有imageview，textview和checkBox
---------------------------------------
<ImageView --- textView --- checkbox >
---------------------------------------
listview有一个onClickListener，复选框有onCheckListener ..
我使用了一个布尔数组（命名为status）来设置复选框，或者在开头时将其初始化为false。
假设列表中有19个项目，我检查它正常工作的第一个项目的复选框，并将布尔数组的索引0更改为true。 但是当我滚动并检查最后一项时，反映了列表的第3个位置，并且布尔数组的索引3变为真。
还会自动检查许多其他复选框。

供参考使用示例
Get Selected Item Using Checkbox in Listview
将适配器类更改为以下。
您需要覆盖getCount并使用SparseBooleanArray
private class MyCustomAdapter extends ArrayAdapter<String> implements CompoundButton.OnCheckedChangeListener{
ArrayList<String> myList;
public MyCustomAdapter(Context context, int textViewResourceId,
ArrayList<String> sList) {
super(context, textViewResourceId, sList);
mCheckStates = new SparseBooleanArray(sList.size());
myList= sList;
}
private SparseBooleanArray mCheckStates;
private class ViewHolder {
TextView text;
CheckBox chkbox;
ImageView imageview;
}
@Override
public int getCount() {
return stg1.size();
}
@Override
public View getView(final int position, View convertView,ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.new_search_adptr, null);
holder = new ViewHolder();
holder.text = (TextView) convertView
.findViewById(R.id.adapterText1);
holder.chkbox = (CheckBox) convertView
.findViewById(R.id.checkBox1);
holder.imageview = (ImageView) convertView
.findViewById(R.id.imageView1);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.chkbox.setTag(position);
holder.chkbox.setChecked(mCheckStates.get(position, false));
holder.chkbox.setOnCheckedChangeListener(this);
holder.text.setText(stg1.get(position).toString());
holder.imageview.setImageBitmap(arr_img.get(position));
return convertView;
}
public boolean isChecked(int position) {
return mCheckStates.get(position, false);
}
public void setChecked(int position, boolean isChecked) {
mCheckStates.put(position, isChecked);
}
public void toggle(int position) {
setChecked(position, !isChecked(position));
}
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
mCheckStates.put((Integer) buttonView.getTag(), isChecked);
}
}
要点击按钮
StringBuilder result = new StringBuilder();
for(int i=0;i<youradapter.mCheckStates.size();i++)
{
if(youradapter.mCheckStates.get(i)==true)
{
result.append(arr_make.get(i).toString()+" "+arr_model.get(i).toString()+" "+arr_ver.get(i).toString());
result.append("\n");
}
}
Toast.makeText(MainActivity.this, result, 1000).show();
}
答案 1 :(得分：1)
在getView()中，您只在新创建的视图上设置选中状态。当视图被回收（convertView != null）时，已检查的状态将是旧的回收视图的状态。
在if (converView == null) ... else部分之后，将“设置checkBoxes”代码部分向上移动一个缩进级别。也就是说，改变你的代码：
if (convertView == null) {
//...
//create view and init holder
//---------- Setting the checkBoxes -----------------------------------
if (status.get(position)) {
holder.chkbox.setChecked(true);
} else {
holder.chkbox.setChecked(false);
}
//...
} else {
holder = (ViewHolder) convertView.getTag();
holder.chkbox.setOnCheckedChangeListener(null);
}
到此：
if (convertView == null) {
//...
//create view and init holder
} else {
holder = (ViewHolder) convertView.getTag();
holder.chkbox.setOnCheckedChangeListener(null);
}
//---------- Setting the checkBoxes -----------------------------------
if (status.get(position)) {
holder.chkbox.setChecked(true);
} else {
holder.chkbox.setChecked(false);
}
