谁能告诉我如何获取自定义视图列表中选中行的值？例如，我的代码有一个自定义视图列表，其中包含两个文本视图和一个复选框。每当用户检查一行并点击提交按钮时，我需要检索两个文本视图中的信息。
代码是
public class contacts extends Activity implements OnItemClickListener {
static final String TAG = "contacts";
ArrayList<String> contactName = new ArrayList<String>();
ArrayList<String> contactNumber = new ArrayList<String>();
MyAdapter myAdapter;
Button AddNumber;
String numberIntent;
View vi;
ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.listview);
getAllContacts(this.getContentResolver());
listView = (ListView) findViewById(R.id.lists);
myAdapter = new MyAdapter();
listView.setAdapter(myAdapter);
listView.setItemsCanFocus(false);
listView.setTextFilterEnabled(true);
// adding
AddNumber = (Button) findViewById(R.id.AddNumbers);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Object listItem = listView.getItemAtPosition(0);
Log.d(TAG,"listView listener" + listItem);
}
});
AddNumber.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
StringBuilder checkedContacts = new StringBuilder();
Log.d(TAG, "onClick" + myAdapter.mCheckStates.size());
for (int i = 0; i < contactName.size(); i++)
{
if (myAdapter.mCheckStates.get(i) == true) {
checkedContacts.append(contactName.get(i).toString());
checkedContacts.append("\n");
} else {
Log.d(TAG, "No OnClick" + contactName.get(i).toString());
}
}
Toast.makeText(contacts.this, checkedContacts,
Toast.LENGTH_LONG).show();
ArrayList<String> checkboxArray = new ArrayList<String>();
myAdapter.mCheckStates = listView.getCheckedItemPositions();
Log.d(TAG, "Sparse" + myAdapter.mCheckStates);
for (int i = 0; i < myAdapter.mCheckStates.size(); i++) {
int position = myAdapter.mCheckStates.keyAt(i);
boolean bool = myAdapter.mCheckStates.valueAt(position);
Log.d(TAG, "Sparse2" + myAdapter.mCheckStates);
}
String[] outputStrArr = new String[checkboxArray.size()];
for (int i = 0; i < checkboxArray.size(); i++) {
outputStrArr[i] = checkboxArray.get(i);
}
}
});
}
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
myAdapter.toggle(arg2);
}
public void getAllContacts(ContentResolver cr) {
Cursor cursor = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC");
while (cursor.moveToNext()) {
String name = cursor
.getString(cursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = cursor
.getString(cursor
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.d(TAG, "getAllContacts" + phoneNumber);
contactName.add(name);
contactNumber.add(phoneNumber);
}
cursor.close();
Intent in = new Intent(this, TrackLogic.class);
in.putExtra("contact", contactName.toArray());
Log.d(TAG, "Intent????" + contactName);
in.putExtra("contact1", contactNumber.toArray());
}
class MyAdapter extends BaseAdapter implements
CompoundButton.OnCheckedChangeListener {
private SparseBooleanArray mCheckStates;
LayoutInflater mInflater;
TextView phoneView, contactView;
CheckBox checkBox;
MyAdapter() {
mCheckStates = new SparseBooleanArray(contactName.size());
mInflater = (LayoutInflater) contacts.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return contactName.size();
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(final int position, View convertView,
ViewGroup parent) {
vi = convertView;
if (convertView == null)
vi = mInflater.inflate(R.layout.row, null);
contactView = (TextView) vi.findViewById(R.id.contact_name);
phoneView = (TextView) vi.findViewById(R.id.phone_number);
checkBox = (CheckBox) vi.findViewById(R.id.checkBox_id);
contactView.setText(contactName.get(position));
phoneView.setText(contactNumber.get(position));
checkBox.setTag(position);
checkBox.setChecked(mCheckStates.get(position, false));
checkBox.setOnCheckedChangeListener(this);
return vi;
}
public boolean isChecked(int position) {
return mCheckStates.get(position, false);
}
public void setChecked(int position, boolean isChecked) {
mCheckStates.put(position, isChecked);
Log.d(TAG, "setChecked");
notifyDataSetChanged();
}
public void toggle(int position) {
setChecked(position, !isChecked(position));
}
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
mCheckStates.put((Integer) buttonView.getTag(), isChecked);
}
}
}
我似乎无法弄清楚，现在它对我来说真的很累。任何帮助都非常感谢..谢谢。
