我想在我的 ListView 中添加 CheckBox 并在另一个 Activity 中通过 CheckBox 显示所选项目。但我不知道该怎么做。我该怎么做？
【问题讨论】：
listview with checkbox的可能重复 【参考方案1】：我觉得这段代码和你的情况类似
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.checklist);
db = new DatabaseHandlerChecklist(this);
initList();
add = (ImageButton) findViewById(R.id.addChecklist);
add.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
AlertDialog.Builder add = new AlertDialog.Builder(
ChecklistActivity.this);
add.setTitle("Add checklist");
add.setIcon(R.drawable.alert_icon);
add.setMessage("Enter text : ");
final EditText content = new EditText(ChecklistActivity.this);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT);
content.setLayoutParams(lp);
add.setView(content);
add.setPositiveButton("OK", new DialogInterface.OnClickListener()
@Override
public void onClick(DialogInterface dialog, int which)
String SContent = content.getText().toString();
if (SContent.equalsIgnoreCase(""))
Toast.makeText(ChecklistActivity.this, "Insert text first !", 2000).show();
else
Checklist check = new Checklist(SContent, 0);
db.insert(check);
adapter.add(check);
adapter.notifyDataSetChanged();
initList();
Toast.makeText(ChecklistActivity.this, "Text added !", 2000).show();
);
add.setNegativeButton("CANCEL", new DialogInterface.OnClickListener()
@Override
public void onClick(DialogInterface dialog, int which)
);
add.show();
);
delete = (ImageButton) findViewById(R.id.deleteChecklist);
delete.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
db.delete();
adapter.notifyDataSetChanged();
initList();
Toast.makeText(ChecklistActivity.this, "Deleted !", 2000).show();
);
public void initList()
list = db.getAll();
adapter = new ChecklistAdapter(this, R.layout.content_checklist, list);
ListView checklist = (ListView) findViewById(R.id.list);
checklist.setAdapter(adapter);
private class ChecklistAdapter extends ArrayAdapter<Checklist>
Context context;
List<Checklist> checklist = new ArrayList<Checklist>();
int layoutResourceId;
public ChecklistAdapter(Context context, int layoutResourceId,
List<Checklist> objects)
super(context, layoutResourceId, objects);
this.layoutResourceId = layoutResourceId;
this.checklist = objects;
this.context = context;
@Override
public View getView(int position, View convertView, ViewGroup parent)
CheckBox chk = null;
if (convertView == null)
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.content_checklist,
parent, false);
chk = (CheckBox) convertView.findViewById(R.id.checkbox);
convertView.setTag(chk);
chk.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
CheckBox cb = (CheckBox) v;
Checklist changeChecklist = (Checklist) cb.getTag();
changeChecklist.setStatus(cb.isChecked() == true ? 1 : 0);
db.update(changeChecklist);
);
else
chk = (CheckBox) convertView.getTag();
Checklist current = checklist.get(position);
chk.setText(current.getContent());
chk.setChecked(current.getStatus() == 1 ? true : false);
chk.setTag(current);
return convertView;
@Override
protected void onDestroy()
super.onDestroy();
db.close();
@Override
public boolean onCreateOptionsMenu(android.view.Menu menu)
super.onCreateOptionsMenu(menu);
MenuInflater floatMenu = getMenuInflater();
floatMenu.inflate(R.menu.float_menu, menu);
return true;
@Override
public boolean onOptionsItemSelected(MenuItem item)
switch(item.getItemId())
case R.id.about :
Intent change = new Intent("com.interactive.writeit.ABOUT");
startActivity(change);
break;
case R.id.help :
Intent change1 = new Intent("com.interactive.writeit.HELP");
startActivity(change1);
break;
case R.id.exit :
AlertDialog.Builder exit = new AlertDialog.Builder(this);
exit.setTitle("Exit");
exit.setMessage("Are you sure want to exit ?");
exit.setPositiveButton("YES", new DialogInterface.OnClickListener()

您必须创建包含包含 Checkbox 和 TextView 的 ListView 内容的 Checklist 对象。
