Android how to create clickable menu from ListView and SimpleMenuAdapter

Android how to create clickable menu from ListView and SimpleMenuAdapter - android

I have problem about SimpleCursorAdapter and ListView. When I want to create dynamic list menu by query from database. The problem is the listview cannot set onClickListener to do something when user click. These are my code.
In file "menu_header.xml"

and the last one is the file that I use to create the menu
public class Menu extends ListActivity {
private ListView listView;
private ImageButton imageButtonSearch;
private Button buttonBack;
private Constants constants = Constants.getInstance();
private Database database = new Database(this);
private Beans beans = Beans.getInstance();
private Context context = this;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu_wrapper);
buttonBack = (Button)findViewById(R.id.bt_back);
imageButtonSearch = (ImageButton)findViewById(R.id.bt_search);
buttonBack.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
finish();
}
});
imageButtonSearch.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent i = new Intent();
i.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivityForResult(new Intent(context, Search.class), beans.REQUEST_CODE);
}
});
listView = this.getListView();
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
Log.d("Item Click","item click");
}
});
database.open();
Cursor cursorPlaceType = database.getPlaceType();
startManagingCursor(cursorPlaceType);
if(cursorPlaceType != null){
String[] columns = new String[]{ constants.PLACE_TYPE_IMAGE, constants.PLACE_TYPE_ENAME, constants.PLACE_TYPE_TNAME };
int[] to = new int[]{ R.id.list_image, R.id.eng_name, R.id.thai_name };
SimpleCursorAdapter menuAdapter = new SimpleCursorAdapter(this, R.layout.menu_choice, cursorPlaceType, columns, to);
menuAdapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
#Override
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
if(view.getId() == R.id.list_image){
try {
String imageFile = constants.IMAGE_ASSETS + cursor.getString(columnIndex) + ".png";
Bitmap bitmap = BitmapFactory.decodeStream(getAssets().open(imageFile));
((ImageView)view).setImageBitmap(bitmap);
} catch (IOException e) { e.printStackTrace(); }
return true;
}//end if
return false;
}//end setViewValue
});
this.setListAdapter(menuAdapter);
}else{
new AlertDialog.Builder(this)
.setMessage("Try again")
.setNeutralButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {

}
}).show();
}
}//end onCreate()
Thank you indeed for your help.

Use protected void onListItemClick(ListView l, View v, int position, long id) this method of ListActivity instead of your listView.setOnItemClickListener method.

Display corresponding details of user when selected from list

I have developed a screen where a no. of people from the database are displayed in a list view. I want to display the profile page of the selected person. So my question is how to bind each detail of the selected person like name, contact, etc. to the profile page which I have created? Will I have to call the getById API in the onItemClickListener?
Here's the edited code:-
public class Test extends AppCompatActivity {
List<Genie> genieList;

Button button;

button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {

new RetrieveFeedTask().execute();

} else {
progressBar.setVisibility(View.GONE);

I want to display the details in the a profile page like this:-
profile page

Please pass the value in Intent using putExtra()
Intent intent = new Intent(Test.this, viewGenie1.class);
intent.putExtra("key","Value"); //Key must be unique and value should be the value which you want to pass to viewGenie1 class.
startActivity(intent);
In viewGenie1 class you can get the value like this
String value="";
if(getIntent().hasExtra("key")) {
value = getIntent().getExtras().getString("key");
}
Please replace
String value = "";
if (getIntent().hasExtra("name")) {
String name = getIntent().getExtras().getString("name");
String add = getIntent().getExtras().getString("add");
String phn = getIntent().getExtras().getString("phn");
String sal = getIntent().getExtras().getString("sal");
String lea = getIntent().getExtras().getString("lea");
}
name.setText(value);
address.setText(value);
contact.setText(value);
salary.setText(value);
leaves.setText(value);
To
String mName = "",mAdd="",mPhn="",mSal="",mLea="";

Android : Unable to delete ListView item from menu

I am new here so please bear with my naivety. I am working on a music player that will display a menu on clicking 'dots' buttton(given in code below) in listview item. Inside the menu there will be a button to delete. The listview is getting populated by a custom adapter. Here is the code of adapter...
private class hashmapAdapter extends BaseAdapter implements Filterable {
HashMap<Integer, NowPlayingActivity.Details> NewDetails = new HashMap<>();
private hashmapAdapter(HashMap<Integer, NowPlayingActivity.Details> hashMap) {
if(NewDetails.size()==0) {
NewDetails.putAll(hashMap);
}
}
#Override
public int getCount() {
return NewDetails.size();
}
#Override
public Object getItem(int position) {
return NewDetails.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
final View result;
if(convertView == null) {
result = LayoutInflater.from(parent.getContext()).inflate(R.layout.single_item,parent,false);
} else {
result = convertView;
}
((TextView)result.findViewById(R.id.Name)).setText(NewDetails.get(position).getName());
((TextView)result.findViewById(R.id.artist)).setText(NewDetails.get(position).getArtist());
((TextView)result.findViewById(R.id.duration)).setText(NewDetails.get(position).getDuration()+" || ");
dots = (Button)result.findViewById(R.id.dots);
dots.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
name = (TextView)result.findViewById(R.id.Name);
LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
View popup_view = inflater.inflate(R.layout.option_layout,null);
RelativeLayout item = (RelativeLayout) popup_view.findViewById(R.id.popup);
final float width= (getResources().getDimension(R.dimen.width_entry_in_dp));
final float height= getResources().getDimension(R.dimen.height_entry_in_dp);
final PopupWindow popupWindow = new PopupWindow(popup_view,Math.round(width),Math.round(height),true);
popupWindow.showAtLocation(item, Gravity.END, 0, 0);
popupWindow.showAsDropDown(dots);
play_next_btn = (Button)popup_view.findViewById(R.id.play_next);
add_to_playlist = (Button)popup_view.findViewById(R.id.add_to_playlist);
share = (Button)popup_view.findViewById(R.id.share);
delete = (Button)popup_view.findViewById(R.id.delete);
delete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
for(int i=0;i<NewDetails.size();i++) {
if(NewDetails.get(i).getName().equals(name.getText().toString())) {
for(int j=0;j<hashMap.size();j++) {
if(hashMap.get(j).getName().equals(name.getText().toString())) {
if (true) {
NewDetails.remove(i);
hashMap.remove(j);
}
}
}
}
}
populate1(NewDetails);
popupWindow.dismiss();
}
});
}
});
return result;}
Now the problem is that after deleting element when i call populate1(NewDetails), it gives a null pointer exception on NewDetails.get(position).getName(). So on repopulating listview i am getting NPE error. Following is the populate1() function code...
public void populate1(HashMap<Integer,NowPlayingActivity.Details> hashMap) {
adapter = new hashmapAdapter(hashMap);
library.setAdapter(adapter);
adapter.notifyDataSetChanged();
library.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
name = (TextView)view.findViewById(R.id.Name);
String SongName = name.getText().toString();
Intent intent = new Intent(getApplicationContext(),NowPlayingActivity.class);
intent.putExtra("SongName",SongName);
setResult(555,intent);
finish();
}
});
}
I have already tried notifydatasetchanged() and listview.invalidateviews(), both didnt work. File is getting deleted but the adapter is not refreshing the list to remove element. Here is the xml layout of single_item for listview....`

The height of ExpandableListView impacts the display of ChildView

I have searched for this issue a few days. Here's the structure of the app.

Here's the behavior: when clicking the group header, no child view is displayed. From LogCat, I can see that getViewGroup() in the adapter is called twice though, but getChildView() is not called at all. After searching the internet and trying them out, I still can't get the child view displayed when clicking on the group header, but when I tried setting the ExpanandableListView height with a fix height, say, 400dp, like this:
<ExpandableListView xmlns:
android:layout_width="match_parent"
android:layout_height="400dp"
android:id="#+id/expLVClaims"/>
the child view is then expanded and collapsed as expected. But the thing is that because the fixed height will makes the ExpandableListView occupy 400dp space vertically, even no data is in the adapter at all, which is unwanted behavior.
Can someone throw some hints?
Thanks in advance!

First thing:
You should not use any scrolling component like expandable list, inside a scroll view here's why Listview inside ScrollView is not scrolling on Android.
Second thing:
Height of ExpandableListView should be match_parent.
I was also facing the same problem related to height, and making ExpandableListView height as match_parent resolved my problem. I think this will help you.

How tochange color of a textView in onclick listener in a list fragment

I was trying to change the color of a text view in a list fragment after onclick button.
Im using an add button(addBtn) to add the contents to list dynamically an another button(clrBtn) to change the color of the textview which is already added to the list
Im getting a nullPointerException. Can you please let me know where am i going wrong
Below is my code :
public class FragmentOne extends ListFragment {
String[] order = new String[] {};
int[] qty;
public FragmentOne(){}
/** Declaring an ArrayAdapter to set items to ListView */
SimpleAdapter adapter1;
// Keys used in Hashmap
String[] from = { "num","itm","price","qty" };
// Ids of views in listview_layout
int[] to = { R.id.num,R.id.itm,R.id.price,R.id.qty};
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView;
Button addBtn,clrBtn;
rootView = inflater.inflate(R.layout.fragment_1, container, false);
addBtn = (Button) rootView.findViewById(R.id.btnAdd);
clrBtn = (Button) rootView.findViewById(R.id.btnClear);
addBtn.setOnClickListener (new OnClickListener() {
#Override
public void onClick(View v) {
//ListFragment fragment=new FragmentProdQtyPrice();
Fragment fragment=new FragmentExListView();
Bundle bundle = new Bundle();
bundle.putInt("fragmentId", 1);
fragment.setArguments(bundle);
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
}
});
clrBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
/*MainActivity.aList.clear();
adapter1=new SimpleAdapter(getActivity().getBaseContext(), MainActivity.aList, R.layout.listview_layout, from, to);
setListAdapter(adapter1);*/
LinearLayout tv=(LinearLayout)arg0.findViewById(R.id.listtest);
tv.setBackgroundColor(Color.parseColor("#FF0000"));
}
});
adapter1=new SimpleAdapter(getActivity().getBaseContext(), MainActivity.aList, R.layout.listview_layout, from, to);
setListAdapter(adapter1);
return rootView;
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
String prompt =
"clicked item: " + getListView().getItemAtPosition(position).toString();
Toast.makeText(getActivity(),prompt , Toast.LENGTH_SHORT).show();
}}

Try this Solution:
You are looking child view in Button element. Button element doesn't have any child element.
clrBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
LayoutInflater inflater = LayoutInflater.from(FragmentOne.this.getActivity().getApplicationContext());
View root = inflater.inflate(R.layout.listview_layout,null);
LinearLayout tv=(LinearLayout)root.findViewById(R.id.listtest);
tv.setBackgroundColor(Color.parseColor("#FF0000"));
}
});

Is there a way for me to implement a listener on a button and upon clicking it, it leads me to the next activity?
thanks and sorry for the long post!

i was able to see upon clicking it but when i put an intent for it to
switch from one activity to another it came with errors. i only used
the log.d to find out whether the button work
startActivity is a method of Activity class. So you need Activity Context. You already have
this.context = context;
So Use
context.startActivity(new Intent(context, commentpage.class));
