我從Database獲取的數據填充ListView。我正在使用CustomAdapter，它擴展了BaseAdapter以填充數據的ListView。 ListView的每一行包含2個TextView和1個CheckBox。現在我想要做的是在Activity的頂部放置一個EditText，當用戶鍵入例如J的文本時，ListView應該顯示所有以J開頭的聯繫人。請引導我。從列表視圖實施搜索過濾器從數據庫填充
FOR MYCUSTOMADAPTER
public class MyCustomAdapter extends BaseAdapter {
Context mContext;
private LayoutInflater mInflater;
SparseBooleanArray mSparseBooleanArray;
private ArrayList<String> mData = new ArrayList<String>();
private ArrayList<String> mNumber = new ArrayList<String>();
public MyCustomAdapter(Context mContext) {
mInflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mSparseBooleanArray = new SparseBooleanArray();
}
public ArrayList<String> getCheckedItems() {
ArrayList<String> mTempArry = new ArrayList<String>();
for (int i = 0; i < mData.size(); i++) {
if (mSparseBooleanArray.get(i)) {
//mTempArry.add(mData.get(i));
mTempArry.add(mNumber.get(i));
}
}
return mTempArry;
}
public int getCount() {
return this.mData.size();
}
public void addItem(String paramString1, String paramString2) {
this.mData.add(paramString1);
this.mNumber.add(paramString2);
notifyDataSetChanged();
}
public Object getItem(int paramInt) {
return (String) this.mData.get(paramInt);
}
public long getItemId(int paramInt) {
return paramInt;
}
public View getView(final int paramInt, View paramView,
ViewGroup paramViewGroup) {
if (paramView == null) {
paramView = mInflater.inflate(R.layout.multiplecontactview, null);
}
TextView txtName = (TextView) paramView.findViewById(R.id.txtContactName);
TextView txtNumber = (TextView) paramView.findViewById(R.id.txtContactNumber);
CheckBox mCheckBox = (CheckBox) paramView.findViewById(R.id.checkBox1);
mCheckBox.setTag(paramInt);
mCheckBox.setChecked(mSparseBooleanArray.get(paramInt));
mCheckBox.setOnCheckedChangeListener(mCheckedChangeListener);
txtName.setTextColor(Color.BLACK);
txtNumber.setTextColor(Color.BLACK);
for (int i = 0; i < mData.size(); i++) {
txtName.setText(mData.get(paramInt).toString());
txtNumber.setText(mNumber.get(paramInt).toString());
}
return paramView;
}
OnCheckedChangeListener mCheckedChangeListener = new OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
mSparseBooleanArray.put((Integer) buttonView.getTag(), isChecked);
}
};
public static class ViewHolder {
public CheckBox cb;
public TextView nameView;
public TextView numberView;
}
}
代碼代碼填充LISTVIEW隨着數據的OnCreate（）
ArrayList<Contact> contacts = db.getAllContacts();
for (Contact cn : contacts) {
mAdapter.addItem(cn.getName(), cn.getPhoneNumber());
}
mAdapter.notifyDataSetChanged();
mListView.setAdapter(mAdapter);

您建議的鏈接由customadapter擴展arrayadapter的示例組成，而我正在擴展baeseadapter。 –
鏈接就像參考而不是實際的代碼。你有你自己的方式實施。至少你有一個想法開始。對於答案你可以看到下面的答案。我只是建議，所以我把它放在評論中。 – Raghunandan
