I want to display the user on the custom listview, each line listview has 2 textview and social network url, when click on the listview will lead to social networking site. I tried but failed, can you suggest me? Thank you very much.
First take a list_view.xml

You are doing wrong you have to get the value from models not from the textview as in your sample you are doing below
TextView prdId = view.findViewById(R.id.name);
prdId.setText(prdId.toString());
you need to get the value from the model like below
prdId.setText(mensWears.get(i).getItemName());
I m trying to add the value from textview dynamically to listview.For that I have created another layout to take the values from user. but I'm not able to do that. I have tried many things. Kindly help.. Here is my code.
package com.example.chetan.assignment;

public class MainActivity extends AppCompatActivity {
private static int count = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// String[] name= {"Apple","Banana","Mango","PineApple"};
//String[] price = {"Rs.40","Rs.60","Rs.70","Rs.80"};
List<String> names = new ArrayList<String>();
//String[] names = {"names"};
List<String> prices = new ArrayList<String>();
//String[] prices = {"prices"};
String name = getIntent().getStringExtra("name");
String price = getIntent().getStringExtra("price");
if(count==0) {
names.add(0, "name");
prices.add(0, "price");
}
if (count>0) {
names.add(count, name);
prices.add(count,price);
}
count++;
ListAdapter MyAdapter = new MyAdapter(names, prices, this);

theList.setAdapter(MyAdapter);
}
public void buttonClick(View view) {
Intent i = new Intent(this, Addlayout.class);
startActivity(i);
}
}
package com.example.chetan.assignment;
package com.example.chetan.assignment;

Here you can do something like this:
Instead of simple listview I have used RecyclerView as it has better performance.
//First create a Data class for name and price
public class Data implements Serializable {
private String name,price;
public Data(){}
public Data(String name,String price){
this.name = name;
this.price = price;
}
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
//your Addlayout class
public class Addlayout extends AppCompatActivity {
List<Data> dataList = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_addlayout);
}
public void Onclickbutton(View view){
EditText nameText = (EditText)findViewById(R.id.editText);
EditText priceText = (EditText)findViewById(R.id.editText2);
String nameData = nameText.getText().toString();
String priceData = priceText.getText().toString();
Data data = new Data(nameData, priceData);
dataList.add(data);
Intent intent = new Intent(this,MainActivity.class);
intent.putExtra("List", (Serializable) dataList);
startActivity(intent);
}
}
//add layout xml
//change layout according to you
<?xml version="1.0" encoding="utf-8"?>

//Then your Listview Adapter

Data data = mDataList.get(position);
holder.name.setText(data.getName());
holder.price.setText(data.getPrice());
}
#Override

return mDataList.size();
}
}
//your Listview layout to show name and price

//And finally the main Activity

This is MainActivity.java in which we used a array to show the values
MainActivity.java
package com.example.chaqeel.taskviews;
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.ListView;

import java.util.Collections;
public class MainActivity extends Activity {

int[] Images = {R.drawable.img1, R.drawable.img2, R.drawable.img3,
R.drawable.img4, R.drawable.img5};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.listview);
lv.setAdapter(new dataListAdapter(Names, Address, Images));
}
class dataListAdapter extends BaseAdapter {
String[] Name, Addres;
int[] imge;
/*dataListAdapter() {

Addres = null;
imge=null;
}*/
public dataListAdapter(String[] text, String[] text1, int[] text3) {
Name = text;
Addres = text1;
imge = text3;
}
public int getCount() {
return Name.length;
}
public Object getItem(int arg0) {
return null;
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup
parent) {
LayoutInflater inflater = getLayoutInflater();
final View row;
row = inflater.inflate(R.layout.randomvalues, parent, false);
final TextView Name, Addres;
ImageView imge;
Name = (TextView) row.findViewById(R.id.name);
Addres = (TextView) row.findViewById(R.id.adress);
imge = (ImageView) row.findViewById(R.id.img);
Name.setText(Names[position]);
Addres.setText(Address[position]);
imge.setImageResource(Images[position]);
final ArrayList<String> lvv= new ArrayList<>();
Collections.addAll(lvv,Names);
// Collection.addAll(lvv,Address);
ImageButton dltbutton = (ImageButton) findViewById(R.id.removebtn);
dltbutton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
lvv.remove(Names);
lvv.remove(Address);
notifyDataSetChanged();
}
});
return (row);
}
}
}
In the onClickListener try the following code
youradapter.notifyDataSetChanged();
In the deletebutton onClickListener try this
Names = ArrayUtils.removeElement(Names,Names[position]);
Address = ArrayUtils.removeElement(Address,Address[position]);
notifyDataSetChanged();
Though it is advised to use OOP concept like a class to hold the Arrays of Names,Address and Images.
Try below code:
dltbutton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Name = ArrayUtils.removeElement(Names, Names[position]);
Address = ArrayUtils.removeElement(Address, Address[position]);
imge = ArrayUtils.removeElement(imge, imge[position]);
notifyDataSetChanged();
}
});
change this:
ImageButton dltbutton = (ImageButton) findViewById(R.id.removebtn);
dltbutton.setTag(position);
dltbutton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Integer index = (Integer) view.getTag();
lvv.remove(index.intValue());
notifyDataSetChanged();
}
});
Are you from Chakwal? I am Chakwalian. Again StackOverflow is telling me that my answer does not meet thier quality requirements.
You need to better idea to use Model class as below:-
create a model class MyModel.class
import java.util.ArrayList;
import java.util.List;
public class MyModel {
String Name, Address;
int image;
public MyModel(String name, String address, int image) {
Name = name;
Address = address;
this.image = image;
}
public String getName() {
return Name;
}
public String getAddress() {
return Address;
}
public int getImage() {
return image;
}
}
and then add with adapter class see below:
import android.app.Activity;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends Activity {
ListView lv;
String[] Names = {"Aqeel", "Ali", "Ansar", "Usama", "Farhad"};
String[] Address = {"Chakwal", "Rawalpindi", "Islamabad", "Lahore",
"Multan"};
int[] Images = {R.drawable.ic_menu_camera, R.drawable.ic_menu_gallery, R.drawable.ic_menu_manage,
R.drawable.ic_menu_send, R.drawable.ic_menu_share};
private List<MyModel> myModel=new ArrayList<>();

add android:onClick="addMore" to your add button
it will fine Happy Coding :)

Solved: I have created an adapter based on #JJV 's suggestion. I am aware that there is plenty of room for improvement, but it works for now.
I have updated this simplified version of my program, with the working code; I hope it will be useful to others:

setContentView(R.layout.main_activity);
Map<Integer, Object> m = new TreeMap<Integer, Object>();
int key = 123;
Item obj1 = new Item("abc", "xyz", 888);
m.put(key, obj1);
key = 456;
Item obj2 = new Item("def", "zyx", 999);
m.put(key, obj2);
ListAdapter adapter = new TreeMapAdapter(this, (TreeMap<Integer, Object>) m);
ListView itemListView = (ListView) findViewById(R.id.itemListView);
itemListView.setAdapter(adapter);
}
public class Item {

Result:
I cannot embed a screenshot of the result in this post, because I do not have 10 reputation, but you can see the result of running the code here: http://i.stack.imgur.com/QoXX1.png
do something like this:
public class TreeMapAdapter extends ArrayAdapter<String> {
private Context context
private TreeMap<Integer, Object> treeMap;
private int mapKeys[];
public TreeMapAdapter(Context context,TreeMap<Integer, Object> treeMap)
this.context=context;
this.treeMao=treeMap;
mapKeys=treemap.keySet().toArray();
}
public int getCount() {
return treeMap.size();
}
public String getItem(int position) {
return treeMap.get(mapKeys[position]);
}
public long getItemId(int position) {
return mapKeys[position];
}
//your getView method....
}
I am fairly new to android development and i'm creating a few simple applications for myself.
I have ran into a problem in relation to animations, in particular a flip animation on each individual cell of a gridview when that cell is clicked.
What my application does so far is retrieves the contacts from the phone and displays the contact photo and the name in a gridview using an array adapter.
What i want to happen is when the user clicks on the grid cell of a contact it will perform a flip animation and display the contacts phone number on the back.
When the user clicks on that cell again it will flip back to the previous view of the name and photo.
I have searched the internet and tried a few tutorials but none that have been of any great help, must of them infact confuse me, so if someone could help that would be great.
I'll post my current code below!
Thanks in advance.
This code is used to retrieve the information of the contacts!
package content;
import android.provider.MediaStore.Images;
public class ContactBean {
private String name;
private String phoneNo;
private String proPic;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhoneNo() {
return phoneNo;
}
public void setPhoneNo(String phoneNo) {
this.phoneNo = phoneNo;
}
public String getProPic() {
return proPic;
}
public void setProPic(String proPic) {
this.proPic = proPic;
}
}

I would go about it something like this.
Let's say this is the layout you're going to inflate in your gridview and it's named view_flipper_layout. Of course you'd have to add all your textview components etc. to either the front or back linearlayout.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ViewFlipper
android:id="#+id/my_view_flipper"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/front"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
<LinearLayout
android:id="#+id/back"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/picture"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</ViewFlipper>
</LinearLayout>
Now let's say this is the adapter
public GridAdapter(Activity act, int row, List<ContactBean> items) {
super(act, row, items);
this.activity = act;
this.row = row;
this.items = items;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
ViewHolder holder;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//here is where you inflate your layout containing your viewflipper
view = inflater.inflate(R.layout.view_flipper_layout, null);
} else {
holder = (ViewHolder) view.getTag();
}
//reference the viewFlipper
ViewFlipper flipper = (viewFlipper) holder.findViewById(R.id.my_view_flipper);
//your front layout should be set to displayed be default
//now you can get get references to your textview or ImageViews contained within the layout
TextView name = (TextView) holder.findViewById(R.id.name);
name.setText("your text");
ImageView picture = (ImageView) holder.findViewById(R.id.picture);
//now you set your onclick and pass it the current viewflipper to control the displayed child
flipper.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View click) {
flipViewFlipper(flipper);
}
});
return view;
}
private void flipViewFlipper(ViewFlipper flipper){
if(flipper.getDisplayedChild() == 0){
flipper.setDisplayedChild(1);
}
else{
flipper.setDisplayeChild(0);
}
}
}
I'm typing this from my head, so just use it as a guide if you attempt to go this way.
