Android ListView帶CheckBox實現單選

第1種方法：

首先是我們的bean：

public class Bean {
    private boolean isChecked;
    private String msg = "這是一條測試數據";
 
    public Bean(){
 
    }
    public Bean(boolean isCheched) {
        this.isChecked = isCheched;
    }
    public boolean isChecked() {
        return isChecked;
    }
    public void setChecked(boolean isChecked) {
        this.isChecked = isChecked;
    }
    public String getMsg() {
        return msg;
    }
    public void setMsg(String msg) {
        this.msg = msg;
    } 
}

然后在getView的時候判斷狀態

public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder mViewHolder;
        if(convertView == null){
            convertView = mInfater.inflate(R.layout.list_item, null);
            mViewHolder = new ViewHolder(convertView);
            convertView.setTag(mViewHolder);
        }else{
            mViewHolder = (ViewHolder) convertView.getTag();
        }
        mViewHolder.mTextView.setText(mDatas.get(position).getMsg());
        if(mDatas.get(position).isChecked()){//狀態選中
            mViewHolder.mCheckBox.setChecked(true);
        }else{
            mViewHolder.mCheckBox.setChecked(false);
        }
        return convertView;
    }

這樣我們就能通過bean的狀態來控制checkBox的選中與否了，但是onItemCLick的時候的操作才是關鍵

public class MainActivity extends ActionBarActivity {
    private ListView mListView;
    private ListAdapter mAdapter;
    private List<bean> mDatas;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mListView = (ListView) findViewById(R.id.main_listView);
        mDatas = new ArrayList<bean>();
        for (int i = 0; i < 20; i++) {
            if(i == 0){//默認選中第一個
                mDatas.add(new Bean(true));
                continue;
            }
            mDatas.add(new Bean(false));
        }
        mAdapter = new ListAdapter(this, mDatas);
        mListView.setAdapter(mAdapter);
        mListView.setOnItemClickListener(mOnItemClickListener);
    }
 
    private final OnItemClickListener mOnItemClickListener = new OnItemClickListener() {
 
        @Override
        public void onItemClick(AdapterView<!--?--> adapterView, View view, int position, long arg3) {
            for (Bean bean : mDatas) {//全部設為未選中
                bean.setChecked(false);
            }
            mDatas.get(position).setChecked(true);//點擊的設為選中
            mAdapter.notifyDataSetChanged();
 
        }
    };
}
