How to make listView with multiple clickable textViews

How to make listView with multiple clickable textViews - android

I am new to android programming. I am working on android app and I have a listview with multiple textViews out of that 2 textViews are Clickable. If user clicks on 'phone' textView it should call to that number and if user clicks on 'street_address' textView it should route it with google maps. Following is my code of my adapter class
class ListViewHolder {
TextView name;
TextView street_address;
TextView phone;
TextView distance;
ListViewHolder(View v)
{
name = (TextView) v.findViewById(R.id.name);
street_address = (TextView) v.findViewById(R.id.address);
phone = (TextView) v.findViewById(R.id.phone);
distance = (TextView) v.findViewById(R.id.distance);
}
}
public class ListDisplayAdapter extends BaseAdapter
{
Context mcontext = null;
public List<NameAddress> listData;
public ListDisplayAdapter(Context context, List<NameAddress> list)
{
mcontext = context;
this.listData = list;
}
#Override
public int getCount() {
return listData.size();
}
#Override
public Object getItem(int i)
{
return listData.get(i);
}
#Override
public long getItemId(int i)
{
return i;
}
#Override
public View getView(int position, View view, ViewGroup viewGroup)
{
View row = view;
ListViewHolder holder = null;
if (row == null)
{
LayoutInflater inflater =(LayoutInflater) mcontext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.list_row, viewGroup, false);
holder=new ListViewHolder(row);
row.setTag(holder);
}
else
{
holder = (ListViewHolder) row.getTag();
}
NameAddress data = listData.get(position);
holder.name.setText(data.getName());
holder.phone.setText(data.getPhone());
holder.street_address.setText(data.toString());
holder.distance.setText(data.getDistance());
return row;
}
}
Following is hte code of activity class
public class ListDisplayActivity extends Activity
{
ListView listView;
public String tag_name;
public List<NameAddress> nameAddressList;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list_display);
listView = (ListView) findViewById(R.id.list);
Intent intent = getIntent();
if(intent!= null)
{
tag_name = intent.getStringExtra("DashItemName");
}
nameAddressList = null;
try
{
XMLDOMParserHandler parser = new XMLDOMParserHandler(tag_name);
nameAddressList = parser.parseXML(getAssets().open("data.xml"));
ListDisplayAdapter listAdapter = new ListDisplayAdapter(this, nameAddressList);
listView.setAdapter(listAdapter);
}
catch (IOException e)
{
e.printStackTrace();
}
}
}
Please tell me how can I code this

try this,
public class ListDisplayAdapter extends BaseAdapter
{
Context mcontext = null;
public List<NameAddress> listData;
public ListDisplayAdapter(Context context, List<NameAddress> list)
{
mcontext = context;
this.listData = list;
}
#Override
public int getCount() {
return listData.size();
}
#Override
public Object getItem(int i)
{
return listData.get(i);
}
#Override
public long getItemId(int i)
{
return i;
}
#Override
public View getView(int position, View view, ViewGroup viewGroup)
{
View row = view;
ListViewHolder holder = null;
if (row == null)
{
LayoutInflater inflater =(LayoutInflater) mcontext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
holder = new ListViewHolder();
row = inflater.inflate(R.layout.list_row, viewGroup, false);
name = (TextView) v.findViewById(R.id.name);
holder.street_address = (TextView) v.findViewById(R.id.address);
holder.phone = (TextView) v.findViewById(R.id.phone);
holder.distance = (TextView) v.findViewById(R.id.distance);
row.setTag(holder);
}
else
{
holder = (ListViewHolder) row.getTag();
}
NameAddress data = listData.get(position);
holder.name.setText(data.getName());
holder.phone.setText(data.getPhone());
holder.phone.settag(data.getPhone());
holder.street_address.setText(data.toString());
holder.street_address.settag(data.toString());
holder.distance.setText(data.getDistance());
holder.phone.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String phoneno = ((Textview)v).gettag();
}
});
holder.street_address.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String streetaddress = ((Textview)v).gettag();
}
});
return row;
}
class ListViewHolder {
TextView name;
TextView street_address;
TextView phone;
TextView distance;
}
}

Android custom listadapter always deleting the last item

Good day,
I am trying to refresh my knowledge in android programming
by creating a simple memo app with custom adapter list.
My problem is, even I call "NotifyDataSetChanged();",
the value deleted in my list is always the last one.
Though when I refresh it, it will display the correct one.
Here is my code :
public class CustomAdapter extends BaseAdapter{
List<Memo> memos;
Context context;
int [] imageId;
private static LayoutInflater inflater = null;
public CustomAdapter(MainActivity mainActivity, List<Memo> _memos) {
memos = _memos;
context = mainActivity;
inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return memos.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return position;
}
public class Holder
{
TextView tv;
TextView tv2;
Button deleteMemoBtn;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
Holder mViewHolder = null;
if (convertView == null) {
mViewHolder = new Holder();
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = vi.inflate(R.layout.list_memo, parent, false);
mViewHolder.tv = (TextView) convertView.findViewById(R.id.textView1);
mViewHolder.tv2 = (TextView) convertView.findViewById(R.id.textView2);
mViewHolder.deleteMemoBtn = (Button) convertView.findViewById(R.id.deleteMemoBtn);
mViewHolder.tv.setText(memos.get(position).getMemoTitle());
mViewHolder.tv2.setText(Integer.toString(memos.get(position).getMemoID()));
mViewHolder.tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "You Clicked " + memos.get(position).getMemoTitle(), Toast.LENGTH_LONG).show();
}
});
mViewHolder.deleteMemoBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "deleted " + Integer.toString(position), Toast.LENGTH_LONG).show();
memos.remove(position);
notifyDataSetChanged();
}
});
}
return convertView;
}
}
Hoping someone can lighten me up why this code is not working.
Thank you!

Try this code.
public class CustomAdapter extends BaseAdapter {
List<Memo> memos;
Context context;
int[] imageId;
private LayoutInflater inflater = null;
public CustomAdapter(Context mainActivity, List<Memo> _memos) {
memos = _memos;
context = mainActivity;
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return memos.size();
}
#Override
public Object getItem(int position) {
return memos.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public class Holder {
TextView tv;
TextView tv2;
Button deleteMemoBtn;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
Holder mViewHolder = null;
if (convertView == null) {
mViewHolder = new Holder();
convertView = inflater.inflate(R.layout.list_memo, parent, false);
mViewHolder.tv = (TextView) convertView.findViewById(R.id.textView1);
mViewHolder.tv2 = (TextView) convertView.findViewById(R.id.textView2);
mViewHolder.deleteMemoBtn = (Button) convertView.findViewById(R.id.deleteMemoBtn);
convertView.setTag(mViewHolder);
} else {
mViewHolder = (Holder) convertView.getTag();
}
mViewHolder.tv.setText(memos.get(position).getMemoTitle());
mViewHolder.tv2.setText(Integer.toString(memos.get(position).getMemoID()));
mViewHolder.tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "You Clicked " + memos.get(position).getMemoTitle(), Toast.LENGTH_LONG).show();
}
});
mViewHolder.deleteMemoBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context, "deleted " + Integer.toString(position), Toast.LENGTH_LONG).show();
memos.remove(position);
notifyDataSetChanged();
}
});
return convertView;
}
}

ViewHolder doesn't work

public class ListViewAdapter extends BaseAdapter {
private Context context;
private LocationDetails[] locationDetails;
public ListViewAdapter(Context c, LocationDetails[] locationDetails) {
context = c;
this.locationDetails = locationDetails;
}
#Override
public int getCount() {
return locationDetails.length;
}
#Override
public Object getItem(int i) {
return null;
}
#Override
public long getItemId(int i) {
return 0;
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
View list;
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (view == null) {
list = new View(context);
list = inflater.inflate(R.layout.listview_layout, null);
TextView name = (TextView) list.findViewById(R.id.location_name);
TextView desc = (TextView) list.findViewById(R.id.location_desc);
ImageView img = (ImageView) list.findViewById(R.id.location_image);
name.setText(locationDetails[i].getLocationName());
desc.setText(locationDetails[i].getLocationDesc());
img.setImageResource(locationDetails[i].getLocationIcon());
} else {
list = (View) view;
}
return list;
}
}
This code is the code before I use viewholder, it works fine. Then I tried to modify it with the use of viewholder, and compile it with gradle, all the image and textviews disappeared, I don't know what's wrong with the code below. Why can't I get any thing shown on the screen?

in my android app, i have got an custom table list, where the data will be dynamic filled.
only the first row should a an static row, which i set programmatically.
i have this function to fill my data into the list
private void showList() {
boolean FirstRow = true;

databaseList.clear();
String query = "SELECT * FROM " + DatabaseHelper.DATABASE_TABLE;

Arrow.setAlpha(0.0f);

}
On the first view, all looks fine.
but if i scroll down and up, random rows get the background color and the onClick function , which only the first row should get.
anyone an idea what i do wrong?

Custom ListView Adapters for multiple TextViews

I am working on an app with multiple TextViews in a ListView, but I seem to have encountered a problem. The list does not appear to get modified.
I'm attachig my code now
public class MainActivity extends ActionBarActivity {
private List<CustomItem> myItem = new ArrayList<>();

listView = (ListView) findViewById(R.id.listView);
completeAdapter = new CompleteAdapter(customItem, this);
listView.setAdapter(completeAdapter);
}
private void populate() {
customItem.add(new CustomItem("Testing","Application"));
}
public void addToList(View view) {
getText = edit.getText().toString();

text1 = st.nextToken().toString();
text2 = st.nextToken().toString();
MainActivity.this.customItem.add(new CustomItem(text1,text2));
MainActivity.this.completeAdapter.notifyDataSetChanged();

public TextView nameView;
public TextView addView;
}
}
This is my CustomIte.java
class CustomItem{
private String name;
private String address;
CustomItem(String name, String address) {
this.name = name;
this.address = address;
}
public String getName() {
return name;
}
public String getAddress() {
return address;
}}
As you can see I've tried with 2 adapters with the same result. There is data contained in the Strings being passed, so I think the problem is with the adapter. (The ids of all the components are perfect) What changes should I make?

Should change in your Adapter
#Override
public int getCount() {
return 0;
}
#Override
public CustomItem getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
to
#Override
public int getCount() {
return items.size();
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public CustomItem getItem(int position) {
return items.get(position);
}

The problem is in your adapter which return a null view (v)
#Override
public int getCount() {
return items.size();
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public CustomItem getItem(int position) {
return items.get(position);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Holder holder;
if(convertView == null){
convertView =LayoutInflater.from(context).inflate(R.layout.item_row, null);
TextView name_text = (TextView)v.findViewById(R.id.name);
TextView address_text = (TextView)v.findViewById(R.id.address);
holder = new Holder();
holder.nameView = name_text;
holder.addView = address_text;
v.setTag(holder);
}
else
holder = (Holder)v.getTag();
CustomItem custom = items.get(position);
holder.nameView.setText(custom.getName());
holder.addView.setText(custom.getAddress());
return convertView ;
}
Hop it helps ;)
