我有複選框和「保存」按鈕的列表視圖。
無論複選框我檢查,然後點擊保存按鈕,我想保存與這些檢查行插入數據庫 這裏的數據是我的代碼Android-在列表視圖中保存複選框狀態
public class CardDetailsAdapter extends BaseAdapter {
private static ArrayList<CardDetails> searchArrayList;
private LayoutInflater mInflater;
private boolean[] itemChecked = new boolean[100];
public CardDetailsAdapter(Context context, ArrayList<CardDetails> results) {
map = new HashMap<Integer, Boolean>();
searchArrayList = results;
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return searchArrayList.size();
}
public Object getItem(int position) {
return searchArrayList.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, final ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.welcomelistview, null);
holder = new ViewHolder();
holder.bankName = (TextView) convertView.findViewById(R.id.BankNameID);
holder.messages = (TextView) convertView.findViewById(R.id.messageID);
holder.chkbox = (CheckBox) convertView.findViewById(R.id.chkBoxID);
System.out.println("is checked==> " + holder.chkbox.isChecked());
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.bankName.setText(searchArrayList.get(position).getBankName());
holder.messages.setText(searchArrayList.get(position).getMessages());
holder.chkbox.setChecked(false);
// save position and checking status into tag
holder.chkbox.setTag(position);
holder.chkbox.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
HashMap<Integer, Boolean> mSimpleAdapter = new HashMap<Integer, Boolean>();
int p = (Integer) (v.getTag());
if (holder.chkbox.isChecked() == true) {
itemChecked[Integer.valueOf(position)] = holder.chkbox.isChecked();
}else{
itemChecked[Integer.valueOf(position)] = holder.chkbox.isChecked();
}
mSimpleAdapter.put(p, itemChecked[position]);
holder.chkbox.setChecked(itemChecked[position]);
}
});
return convertView;
}
static class ViewHolder {
TextView bankName;
TextView messages;
CheckBox chkbox;
}}
和活動類
import com.ispl.CFSMS.helper.CardDetailsAdapter;
public class WelcomePage extends Activity{
CardDetailsAdapter mListAdapter;
ArrayList<Integer> arList = new ArrayList<Integer>();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.welcomepage);
final ArrayList<CardDetails> cardResults = GetCardDetails();
final ListView welcomelist = (ListView) findViewById(R.id.welcomelistID);
welcomelist.setAdapter(new CardDetailsAdapter(this, cardResults));
welcomelist.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> a, View v, int position, long id) {
Object o = welcomelist.getItemAtPosition(position);
CardDetails fullObject = (CardDetails)o;
Intent r=new Intent(WelcomePage.this , CardMenuActivity.class);
r.putExtra("BankName", fullObject.getBankName());
r.putExtra("CardNumber", fullObject.getCardNumber());
startActivityForResult(r, position);
return false;
}
});
CheckBox checkbox = (CheckBox)findViewById(R.id.chkBoxID);
Button saveTODbBtn = (Button)findViewById(R.id.saveID);
saveTODbBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//get the checkbox status and save related details into database
Intent intent=new Intent(WelcomePage.this, BankProjectActivity.class);
startActivity(intent);
}
});
}
private ArrayList<CardDetails> GetCardDetails(){
ArrayList<CardDetails> carddetailresults = new ArrayList<CardDetails>();
CardDetails sr1 = new CardDetails();
sr1.setBankName("Select All");
sr1.setCardNumber("");
sr1.setMessages("");
carddetailresults.add(sr1);
sr1 = new CardDetails();
sr1.setBankName("HDFC Bank" +" "+ "xxxxx1234");
sr1.setMessages("Messages: " + "10");
carddetailresults.add(sr1);
sr1 = new CardDetails();
sr1.setBankName("ICICI" + " "+ "xxxxx2134");
sr1.setMessages("Messages: 5");
carddetailresults.add(sr1);
sr1 = new CardDetails();
sr1.setBankName("HSBC" + " "+ "xxxxx8796");
sr1.setMessages("Messages: 2");
carddetailresults.add(sr1);
return carddetailresults;
}}
在Adaptar類我我能夠獲得狀態。但我如何保存這些狀態並獲得活動類中的所有狀態,以便在單擊保存按鈕時保存與那些已檢查行相關的所有數據......?
