You can achieve this by storing the reference previously clicked button
private Button prevDelete;
And change click listener to something like below:
select_option.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(prevDelete!=null){
prevDelete.setVisibility(View.INVISIBLE);
}
delete.setVisibility(View.VISIBLE);
prevDelete = delete;
select_option.startAnimation(animation);
selectdelete = v;
Toast.makeText(context, "Edit", Toast.LENGTH_LONG).show();
}
});

I'm using a custom listview which I want to add an item to my listview. But it seems to be skipping all the code to add the item. Can someone please tell me how I should adjust my code to achieve this.
Thank you in advance.

You have this
ArrayList<MessageItem> items = new ArrayList<MessageItem>();
before onCreate
while this
ArrayList<MessageItem> items = new ArrayList<MessageItem>();
in MessageFeedData() is local.
Use a single list and add items to the same then call notifyDateSetChanged() to refresh listview.
As you can see you do not use items as an arg to constructor
final ActivityAdapter itemAdapter = new ActivityAdapter(getApplicationContext(), this.MessageFeedData());
Edit:
final ListView listView = (ListView) this.findViewById(R.id.messagingListView);
items = this.MessageFeedData());
final ActivityAdapter itemAdapter = new ActivityAdapter(getApplicationContext(), items);
I want to make an app which includes a listView with check boxes and a two buttons named add and delete selected. I want to delete all the item that are checked in the list view.I am unable to do that despite of my lot of efforts. Any help would be appreciated.
Here is my code
package com.example.chkbokinlistview;
public class Adapter extends ArrayAdapter<Movies> {
ArrayList<Movies> data;
Context context;
int id;
private Holder h;
public Adapter(Context context, int textViewResourceId, ArrayList<Movies> objects) {
super(context, textViewResourceId, objects);
this.data = objects;
this.context = context;
this.id = textViewResourceId;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final int p = position;
View v = convertView;
LayoutInflater l = ((Activity)context).getLayoutInflater();
h = new Holder();
if (v == null) {
v = l.inflate(id, parent, false);
h.tv = (TextView) v.findViewById(R.id.textView1);
h.cb = (CheckBox) v.findViewById(R.id.checkBox1);
v.setTag(h);
}else{
h = (Holder) v.getTag();
h.cb.setChecked(true);
}
h.tv.setText(data.get(position).movieName);
h.cb.setChecked(data.get(position).deleted);
return v;
}
public void delete(){
//how to delete all the items that are checked
}
class Holder{
TextView tv;
CheckBox cb;
}
}
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.lv);
bDelete = (Button) findViewById(R.id.bDelete);
bAdd = (Button) findViewById(R.id.bAdd);
list = new ArrayList<Movies>();
a = new Adapter(this, R.layout.listitem, list);
lv.setAdapter(a);
bDelete.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
a.delete();
}
});
bAdd.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
final EditText et = new EditText(MainActivity.this);
dialog = new AlertDialog.Builder(MainActivity.this)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface arg0, int arg1) {
// TODO Auto-generated method stub
list.add(new Movies(et.getText().toString(), false));
a.notifyDataSetChanged();
dialog.dismiss();
}
})
.setTitle("ADD Movie")
.setView(et)
.create();
dialog.show();
}
});
}
On checking the checkbox add that position in an ArrayList let say toBeDeleted, and when you click delete button, just remove items from your ArrayList named data according to the positions that you have in toBeDeleted and call the adapter method notifyDataSetChanged().
Add a checkedChangedListener in the getView method for your CheckBox.
h.cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton arg0,
boolean arg1) {
// TODO Auto-generated method stub
if (arg1) {
list.add(position);
} else {
for (int i = 0; i < list.size(); i++) {
if (list.get(i) == position) {
list.remove(i);
break;
}
}
}
}
});
Where list is a ArrayList<Integer>,
and for deleting
private void delete() {
for(int i = 0 i<list.size;i++)
data.remove(list.get(i));
}
but before deleting you have to sort the list in decending order, in order to remove correctly, otherwise you may get an IndexOutofBoundException
I have a listactivity app , consist of 5 rows , each row contain one TEXT and 5 BUTTON , both text and buttons are clickable , text will open MyDay activity whic is textview and when you click any button it must open videoview screen .

Here is a good Handling Button clicks in a ListView Row tutorial.
My ListView consist an ImageView and a TextView I need to get the Text from the TextView.
int the position of my list where I press (onItemClick).
How can I do that?
The 1 class have a Button then when you press I moving to the next activity (CountryView)
and expect to get back from the next activity with a text (name of the selected Country)
The 2 classes have a ListView (ImageView and TextView) the data is getting from a database and showing on the ListView.
My problem is to get back to the 1 class the selected name of the country.
Thanks so much for helping!!!

When you add things to the list, you can add hashmaps to the arraylist which the adapter looks at. Then you can grab the values which are name value pairs.
I think you want to get the position of the list you clicked, Its simple you can use OnItemClickListener as follows
YourList.setOnItemClickListener(new OnItemClickListener(){
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
int position=arg2;
// where position is the clicked position
} }
If you stored your data in String array pass this position say array[position] to string array you can get the Text..
