这就是我使用 ActionBar Search 小部件进行基本搜索的方式。这显然是在布局中的 listView 中提供建议的简单方法。但我想要搜索框本身内的建议。虽然可以在普通搜索框中执行此操作，但我如何使用操作栏搜索框执行相同操作。
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
menu.add(0, 1, 1,"Search").setIcon(R.drawable.ic_search_inverse).setActionView(R.layout.collapsible_edittext).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item) {
switch (item.getItemId()) {
case 1:
search = (AutoCompleteTextView) item.getActionView();
search.addTextChangedListener(filterTextWatcher);
search.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
return true;
}
return false;
}
private TextWatcher filterTextWatcher = new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
// your search logic here
doGeoSearch(String.valueOf(s));
}
};
public void doGeoSearch(String query){
Geocoder geocoder;
ArrayList<Address> addresses;
ArrayList<String> address = new ArrayList<String>() ;
geocoder = new Geocoder(this, Locale.getDefault());
try {
addresses = (ArrayList<Address>) geocoder.getFromLocationName(query, 6);
Log.d("Address",String.valueOf(addresses));
for(int i = 0;i<addresses.size();i++)
{
String addr = new String();
addr.concat(addresses.get(i).getAddressLine(0));
addr.concat(addresses.get(i).getAddressLine(1));
addr = addresses.get(i).getAddressLine(0) + addresses.get(i).getLocality() + addresses.get(i).getAdminArea();
//addr.concat(addresses.get(i).getAddressLine(2));
Log.d("addr",addr);
address.add(addr);
}
SearchAddressAdapater addressList = new SearchAddressAdapater(getApplicationContext(),R.layout.search_list,addresses, LocationActivity.this);
//addressView.setAdapter(addressList);
//ListView addressListView = new ListView();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
