還是先來看看是不是你想要的效果： 
不廢話，直接上代碼，很簡單，代碼里都有注釋
1 單選
public class SingleActivity extends AppCompatActivity { PRivate ListView listView; private ArrayList<String> groups; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_single); listView = (ListView) this.findViewById(R.id.lvGroup); groups = new ArrayList<String>(); groups.add("11"); groups.add("22"); groups.add("33"); groups.add("44"); groups.add("55"); groups.add("66"); groups.add("77"); AdapterView.OnItemClickListener listItemClickListener = new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // 取得ViewHolder對象，這樣就省去了通過層層的findViewById去實例化我們需要的cb實例的步驟 SingleAdapter.ViewHolder viewHolder = (SingleAdapter.ViewHolder) view.getTag(); viewHolder.cb.toggle();// 把CheckBox的選中狀態改為當前狀態的反,gridview確保是單一選中 } }; SingleAdapter adapter = new SingleAdapter(this, groups); listView.setAdapter(adapter); listView.setOnItemClickListener(listItemClickListener); }}Adapter：
public class SingleAdapter extends BaseAdapter { private Activity activity;//上下文 private ArrayList<String> list; private LayoutInflater inflater = null;//導入布局 private int temp = -1; public SingleAdapter(Activity context, ArrayList<String> list) { this.activity = context; this.list = list; inflater = LayoutInflater.from(context); } @Override public int getCount() { return list.size(); } @Override public Object getItem(int position) { return list.get(position); } @Override public long getItemId(int position) { return position; } //listview每顯示一行數據,該函數就執行一次 @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; if (convertView == null) {//當第一次加載ListView控件時 convertView為空 convertView = inflater.inflate(R.layout.group_item_view, null);//所以當ListView控件沒有滑動時都會執行這條語句 holder = new ViewHolder(); holder.tv = (TextView) convertView.findViewById(R.id.item_tv); holder.cb = (CheckBox) convertView.findViewById(R.id.item_cb); convertView.setTag(holder);//為view設置標簽 } else {//取出holder holder = (ViewHolder) convertView.getTag(); } //設置list的textview顯示 holder.tv.setTextColor(Color.WHITE); holder.tv.setText(list.get(position)); // 根據isSelected來設置checkbox的選中狀況 holder.cb.setId(position);//對checkbox的id進行重新設置為當前的position holder.cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) { if (isChecked) {//實現checkbox的單選功能,同樣適用于radiobutton if (temp != -1) { //找到上次點擊的checkbox,并把它設置為false,對重新選擇時可以將以前的關掉 CheckBox tempCheckBox = (CheckBox) activity.findViewById(temp); if (tempCheckBox != null) tempCheckBox.setChecked(false); } temp = compoundButton.getId();//保存當前選中的checkbox的id值 } } }); if (position == temp)//比對position和當前的temp是否一致 holder.cb.setChecked(true); else holder.cb.setChecked(false); return convertView; } public static class ViewHolder { TextView tv; CheckBox cb; }}多選：
public class MulActivity extends AppCompatActivity { private ListView listView; private ArrayList<String> groups; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_mul); listView = (ListView) this.findViewById(R.id.list); groups = new ArrayList<>(); groups.add("11"); groups.add("22"); groups.add("33"); groups.add("44"); groups.add("55"); groups.add("66"); groups.add("77"); AdapterView.OnItemClickListener listItemClickListener = new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // 取得ViewHolder對象，這樣就省去了通過層層的findViewById去實例化我們需要的cb實例的步驟 MulAdapter.ViewHolder viewHolder = (MulAdapter.ViewHolder) view.getTag(); viewHolder.cb.toggle();// 把CheckBox的選中狀態改為當前狀態的反,gridview確保是單一選中 MulAdapter.getIsSelected().put(position, viewHolder.cb.isChecked());//將CheckBox的選中狀況記錄下來 } }; MulAdapter adapter = new MulAdapter(this, groups); listView.setAdapter(adapter); listView.setOnItemClickListener(listItemClickListener); }}Adapter：
public class MulAdapter extends BaseAdapter { private Context context;//上下文 private ArrayList<String> list; //控制CheckBox選中情況 private static HashMap<Integer, Boolean> isSelected; private LayoutInflater inflater = null;//導入布局 public MulAdapter(Context context, ArrayList<String> list) { this.context = context; this.list = list; inflater = LayoutInflater.from(context); isSelected = new HashMap<Integer, Boolean>(); initData(); } private void initData() {//初始化isSelected的數據 for (int i = 0; i < list.size(); i++) { getIsSelected().put(i, false); } } @Override public int getCount() { return list.size(); } @Override public Object getItem(int position) { return list.get(position); } @Override public long getItemId(int position) { return position; } //listview每顯示一行數據,該函數就執行一次 @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; if (convertView == null) {//當第一次加載ListView控件時 convertView為空 convertView = inflater.inflate(R.layout.group_item_view, null);//所以當ListView控件沒有滑動時都會執行這條語句 holder = new ViewHolder(); holder.tv = (TextView) convertView.findViewById(R.id.item_tv); holder.cb = (CheckBox) convertView.findViewById(R.id.item_cb); convertView.setTag(holder);//為view設置標簽 } else {//取出holder holder = (ViewHolder) convertView.getTag();//the Object stored in this view as a tag } //設置list的textview顯示 holder.tv.setTextColor(Color.WHITE); holder.tv.setText(list.get(position)); // 根據isSelected來設置checkbox的選中狀況 holder.cb.setChecked(getIsSelected().get(position)); return convertView; } public static class ViewHolder { TextView tv; CheckBox cb; } public static HashMap<Integer, Boolean> getIsSelected() { return isSelected; } public static void setIsSelected(HashMap<Integer, Boolean> isSelected) { MulAdapter.isSelected = isSelected; }}簡單吧，哈哈哈。。。
