Adding a remove button in my item list

Adding a remove button in my item list - java

I am fairly new to Java and Android development. I am currently creating a shopping app and was looking at adding a "Remove" button to my Shopping Cart list.
Here is my current code for my list activity for my shopping cart, I am not really sure where to begin and some guidance would be greatly appreciated.
Thanks

XML for adapter_product_list
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="8dp">

Change your xml like following
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="8dp" >
<ImageView
android:id="#+id/product_image"
android:layout_width="54dp"
android:layout_height="54dp"
android:layout_alignParentLeft="true"
android:padding="5dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/product_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/product_image"
android:layout_toRightOf="#+id/product_image"
android:text="adjkajdjk"
android:textColor="#446688"
android:textSize="20sp" />
<TextView
android:id="#+id/product_info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/product_title"
android:layout_toRightOf="#+id/product_image"
android:text="adjkajdjk"
android:textColor="#777777"
android:textSize="16sp"
android:textStyle="italic" />
<Button
android:id="#+id/delete_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Delete" />
</RelativeLayout>
And in your adapter inside getView() function add this
Button deleteBtn = (Button) findViewById(R.id.delete_btn);
deleteBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v)
{
itemList.remove(position);
notifyDataSetChanged();
}
});

1) hope p.loadImage(imgView, 54, 54); is running in a asyncTask
2) if you want to click on a button in a row of a ListView than you shoudl add the button to your row layout and implent onClickListenr of that button in your getView method of adapter.in onClick method yous hould have:
if(position<itemList.size()){
//TO REMOVE TEM FROM ARRAY LIST
itemList.remove(position);
//TO Update the ListView
notifyDataSetChanged();
}
you can implement a multy line delete,by adding a checkbox in your listRow and adding the positon of the item to be deleted to an arrayList of Integers and after click-ing the delete button you should delete all the items from the imteList and after that call notifyDataSetChanged()
EDIT
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="8dp">
<ImageView
android:id="#+id/product_image"
android:layout_width="54dp"
android:layout_height="54dp"
android:padding="5dp"
android:layout_alignParentLeft="true" />
<TextView
android:id="#+id/product_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/product_image"
android:layout_alignTop="#+id/product_image"
android:textColor="#446688"
android:textSize="20sp" />
<TextView
android:id="#+id/product_info"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/product_image"
android:layout_below="#+id/product_title"
android:textColor="#777777"
android:textSize="16sp"
android:textStyle="italic" />
<Button
android:id="#+id/deleteBtn"
android:layout_width="wrap_content
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/product_info"
</RelativeLayout>
you should add this button to your layout, and in getView method of adapter add
Button delete=v.findViewById(R.id.deleteBtn);
delete.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
//THE PART I WROTE ABOVE
}
})

Refresh/update listview current tab

I have three tabs with an unique fragment. How by images:
3 tab and a fragment
First problem is that when I click on "I watch it" on a movie and swipe on Watched's tab, this tab isn't updated.

After if I swipe/tap on Notify's tab and comeback on Watched's tab, the tab has been updated. Why? Where am I wrong?

Tap Notify's tap (believe also could tap on Suggested) and tap again Watched's tap
Second problem
In Watched's tab the textView are cut, why? How can I solve this?

For first, you can try adding similar logic to onPageScrolled
Fragment getFragment = getSupportFragmentManager().getFragments().get(position);
if (getFragment instanceof MoviesFragment) {
MoviesFragment thisFragment = (MoviesFragment) getFragment;
if ((position == 0 || position == 2) && positionOffset == 0.0 && positionOffsetPixels == 0)
thisFragment.onRefresh();
}

OK, #user47845 for (This is my list_item_movie.xml) you can try changed to this and tell us how are you doing.

MainActivity.java is :
package com.affinityapp.sj.alphabet;
import android.content.Context;
import android.os.Bundle;
import android.support.design.widget.CollapsingToolbarLayout;
import android.support.design.widget.CoordinatorLayout;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.widget.GridView;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
Toolbar toolbar;
CollapsingToolbarLayout collapsingToolbarLayoutAndroid;
CoordinatorLayout rootLayoutAndroid;
GridView gridView;
Context context;
ArrayList arrayList;
public static String[] gridViewStrings = {
"ALPHABETS",
"NUMBERS",
"MONTH",
"DAYS",
"ANIMALS",
"CALL US",
};
public static int[] gridViewImages = {
R.drawable.icon_alphabet,
R.drawable.icon_number,
R.drawable.icon_calendar,
R.drawable.icon_days,
R.drawable.icon_animal,
R.drawable.icon_call
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
gridView = (GridView) findViewById(R.id.grid);
gridView.setAdapter(new CustomAndroidGridViewAdapter(this, gridViewStrings, gridViewImages));
initInstances();
}
private void initInstances() {
rootLayoutAndroid = (CoordinatorLayout) findViewById(R.id.android_coordinator_layout);
collapsingToolbarLayoutAndroid = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar_android_layout);
collapsingToolbarLayoutAndroid.setTitle("e-Learning");
}
}
CustomAndroidGridViewAdapter.java is :
package com.affinityapp.sj.alphabet;
/**
* Created by SJ on 23-01-2017.
*/
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
/**
* Created by HP on 5/11/2016.
*/
public class CustomAndroidGridViewAdapter extends BaseAdapter {
private Context mContext;
private final String[] string;
private final int[] Imageid;
public CustomAndroidGridViewAdapter(Context c,String[] string,int[] Imageid ) {
mContext = c;
this.Imageid = Imageid;
this.string = string;
}
#Override
public int getCount() {
return string.length;
}
#Override
public Object getItem(int p) {
return null;
}
#Override
public long getItemId(int p) {
return 0;
}
#Override
public View getView(int p, View convertView, ViewGroup parent) {
View grid;
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
grid = new View(mContext);
grid = inflater.inflate(R.layout.gridview_custom_layout, null);
TextView textView = (TextView) grid.findViewById(R.id.gridview_text);
ImageView imageView = (ImageView)grid.findViewById(R.id.gridview_image);
textView.setText(string[p]);
imageView.setImageResource(Imageid[p]);
} else {
grid = (View) convertView;
}
return grid;
}
}

So, you can use this way to click grid view:
public class MainActivity extends AppCompatActivity {
Toolbar toolbar;
CollapsingToolbarLayout collapsingToolbarLayoutAndroid;
CoordinatorLayout rootLayoutAndroid;
GridView gridView;
Context context;
ArrayList arrayList;
public static String[] gridViewStrings = {
"ALPHABETS",
"NUMBERS",
"MONTH",
"DAYS",
"ANIMALS",
"CALL US",
};
public static int[] gridViewImages = {
R.drawable.icon_alphabet,
R.drawable.icon_number,
R.drawable.icon_calendar,
R.drawable.icon_days,
R.drawable.icon_animal,
R.drawable.icon_call
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
gridView = (GridView) findViewById(R.id.grid);
gridView.setAdapter(new CustomAndroidGridViewAdapter(this, gridViewStrings, gridViewImages));
initInstances();
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
// Do whatever you want, like start new Activity or display new view or display dialog box or display just message
Toast.makeText(MainActivity.this, "" + position, Toast.LENGTH_SHORT).show();
}
});
}
private void initInstances() {
rootLayoutAndroid = (CoordinatorLayout) findViewById(R.id.android_coordinator_layout);
collapsingToolbarLayoutAndroid = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar_android_layout);
collapsingToolbarLayoutAndroid.setTitle("e-Learning");
}
}
Hope, this will help you.

Implement onItemClickListener method in you activity:
gridview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
final Intent intent;
switch(position)
{
case 0:
intent = new Intent(context, FirstActivity.class);
break;
case 1:
intent = new Intent(context, SecondActivity.class);
break;
...
default:
intent = new Intent(context, DefaultActivity.class);
break;
}
startActivity(intent);
}
});

Possibly duplicate question...
Research thoroughly before posting a question please.
Answer can be found in this thread: How can I give an imageview click effect like a button on Android?
Edit:
In your current activity, you need to create a variable ImageButton.
ImageButton myButton = (ImageButton) findViewById(R.id.the_button_you_created_on_the_layout.xml);
Then you need to set a click listener to this button
myButton.setOnClickListener(new View.OnClickListner(){
// When the button is pressed/clicked, it will run the code below
#Override
public void onClick()
// Intent is what you use to start another activity
Intent myIntent = new Intent(this, YourActivity.class);
startActivity(intent);
}
});

runtime error in customAdapter

I'm trying to create a list of Card view using a custom adapter. I have defined the layout of a single row of list, consisting a card view and imageview/textviews in it, in a separate .xml file. I'm using a custom srrsy adapter. My app crashes when I try to open the activity having list view , giving only an Runtime-exception error.
Error:

How to insert checkbox on custom listview

I am trying to add a checkbox in a customized listview but don't know how.
I have the following codes:
ListObject.java
package br.com.eduvm.xurrascalc;
public class ListObject {
private String texto;
private int iconeRid;
public ListObject() {
}
public ListObject(String texto, int iconeRid) {
this.texto = texto;
this.iconeRid = iconeRid;
}
public int getIconeRid() {
return iconeRid;
}
public void setIconeRid(int iconeRid) {
this.iconeRid = iconeRid;
}
public String getTexto() {
return texto;
}
public void setTexto(String texto) {
this.texto = texto;
}
}
ListAdapter.java
package br.com.eduvm.xurrascalc;
import java.util.ArrayList;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.CheckBox;
import android.widget.ImageView;
import android.widget.TextView;
public class ListAdapter extends BaseAdapter {
private LayoutInflater mInflater;
private ArrayList<ListObject> itens;
public ListAdapter(Context context, ArrayList<ListObject> itens) {
// Itens que preencheram o listview
this.itens = itens;
// responsavel por pegar o Layout do item.
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return itens.size();
}
public ListObject getItem(int position) {
return itens.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View view, ViewGroup parent) {
ListObject item = itens.get(position);
view = mInflater.inflate(R.layout.itens_lista, null);
((TextView) view.findViewById(R.id.text)).setText(item.getTexto());
((ImageView) view.findViewById(R.id.imagemview)).setImageResource(item.getIconeRid());
return view;
}
}
List.xml
<?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="horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:padding="5sp" >
<ImageView
android:id="#+id/imagemview"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
<TextView
android:id="#+id/text"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="5sp"
android:gravity="center_vertical"
android:textColor="#FFF" />
</LinearLayout>
</LinearLayout>
How could I do to insert a checkbox in the items in this list?

This would be the layout for each individual row in your list
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<CheckBox
android:id="#+id/lstChkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/lstText"
android:textSize="30px"
android:layout_weight="1" />
<ImageView
android:id="#+id/listImage"
android:layout_height="wrap_content"
android:layout_width="wrap_content" />
You main list activity layout will look something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"
android:choiceMode="multipleChoice"
/>
Your class which extends BaseAdapter getView method will somethings like this:
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder vHolder = null;
if (convertView != null)
vHolder = (ViewHolder) convertView.getTag(); // convertView is been recycled
else {
convertView = (View) mInflater.inflate(R.layout.list_item, null); // Set content of new View with list_item.xml
vHolder = new ViewHolder();
vHolder.checkBox = ((CheckBox) convertView.findViewById(R.id.lstChkbox)); // Getting pointers
vHolder.textView = ((TextView) convertView.findViewById(R.id.lstText));
vHolder.imageView = ((ImageView) convertView.findViewById(R.id.listImage));
vHolder.checkBox.setOnCheckedChangeListener(this); // Setting Listeners
convertView.setTag(vHolder);
}
vHolder.checkBox.setId(position); // This is part of the Adapter APi
vHolder.textView.setId(position); // Do not delete !!!
vHolder.imageView.setId(position);
if (mItems.get(position).getChecked()) { // Setting parameters for the View from our mItems list
vHolder.checkBox.setChecked(true);
} else {
vHolder.checkBox.setChecked(false);
}
vHolder.textView.setText(mItems.get(position).getText());
vHolder.imageView.setImageDrawable(mItems.get(position).getmImage());
return convertView;
}
public static class ViewHolder {
CheckBox checkBox;
TextView textView;
ImageView imageView;
}
/*
* Ok for this test but Toast are going to show every time the row comes into View
*/
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
Log.d(TAG, "Checked");
int position = buttonView.getId();
if (isChecked) {
mItems.get(position).setChecked(true);
Toast.makeText(context, mItems.get(position).getText(), Toast.LENGTH_LONG).show();
} else {
mItems.get(buttonView.getId()).setChecked(false);
}
}

Just add a checkbox to the layout itens_lista.xml.
Just adding a checkbox is easy. Do you want to do anything more to ti.

Add a CheckBox View to your custom row layout.

CustomeViewActivity.java
package naresh.custom.view;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.HashMap;
import android.app.ListActivity;
public class CustomeViewActivity extends ListActivity implements OnItemClickListener{
static final ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String,String>>();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
list.removeAll(list);
ListView lista=(ListView)findViewById(android.R.id.list);
int count = lista.getChildCount();
SimpleAdapter adapter = new SimpleAdapter(
this,
list,
R.layout.custom_row_view,
new String[] {"title","description"},
new int[] {R.id.textView1,R.id.textView2}
);
if(count<5){
HashMap<String,String> temp = new HashMap<String,String>();
temp.put("title","On/Off");
temp.put("description", "Alert to be On or Off");
list.add(temp);
HashMap<String,String> temp1 = new HashMap<String,String>();
temp1.put("title","Select tone");
temp1.put("description", "Select tone for alerting");
list.add(temp1);
HashMap<String,String> temp2 = new HashMap<String,String>();
temp2.put("title","Alert Time");
temp2.put("description", "Select Time for alerting Before/After");
list.add(temp2);
HashMap<String,String> temp3 = new HashMap<String,String>();
temp3.put("title","Change Password");
temp3.put("description", "Can cahnge password any time");
list.add(temp3);
setListAdapter(null);
setListAdapter(adapter);
}
getListView().setOnItemClickListener(this);
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
Toast.makeText(this,"ITem clicked", Toast.LENGTH_LONG).show();
}
}

I think you are using CustomAdapter to populate the listview..
If So then in getView() include the the button action:
public View getView(final int position, View convertView, ViewGroup parent)
{
View row=convertView;
FetchHolder holder=null;
if (row==null)
{
LayoutInflater inflater=getLayoutInflater();
row=inflater.inflate(R.layout.grid, parent, false);
holder=new FetchHolder(row);
row.setTag(holder);
}
else
{
holder=(FetchHolder)row.getTag();
}
holder.button.setOnClickListener(new OnClickListener()
{
public void onClick(View v) {
}
});
return row;
}
}
static class FetchHolder
{
private Button time=null;
FetchHolder(View row)
{
time=(Button)row.findViewById(R.id.timebutton);
}
