Pressing Search button clears all items / models on List View

Pressing Search button clears all items / models on List View - android

My ListView works fine on start up. The problem is that whenever I click the search Button which triggers the search view, all items on my ListView disappears. Even after I clear the text field on my searchview, my ListView still is on a state where it is empty.

Changing single row affecting multiple rows randomly multiple rows in Recyclerview in android?

I am creating a ecommerce application. In which I am managing Cart screen.
The cart screen is included in HomeFragment's layout. From the adapter I am calling interface to transfer the data and update to the cart screen which appears when the cart value is greater than -> 0.
The problem is that when I click on "Add to cart" button of any item from recyclerview the "Add to cart" disappers and counter layout appears. as shown in the below images.
Clicking on single item ther other rows's "Add to cart" button disappears which must be not disapper. It is affecting multiple rows on single row change.
How to solve that issue any solution from your side?

Launch Intent on click of ExpandableListView

Good evening everyone !
I am currently working on an ExpandableListView.
The parent contains 1 ImageView.
The child contains 1 TextView and 3 Buttons.
In terms of display, no problem: everything works as I want.
However, I want to add actions to my buttons and I realize that when I put a SetOnclickListener in the getChildView I am not able to launch a new INTENT.
The examples I find on the internet seem to show only clicks on dynamic elements. However, the buttons are not dynamic in my case.
I planned to use a variable to do a SWITCH and thus launch the right INTENT.
But since it doesn't work, I wonder if my direction is the right one.

Can somoene help me ?
I want to start a new intent on click on Button.
Edit : i add child Click Listener on MainActivity but its works only if i set clickable,focusable = false on the 3 Buttons in layout list_item.xml.
And than the click is on the complete child. I can't say if the click is on Button 1, 2 or 3.
Can we fix it ?

Problem solved.
I do this in ExpandableListAdapter in getChildView.
param.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent next = new Intent(parent.getContext(), parametres.class);
parent.getContext().startActivity(next);
}
});

RecylerView does not list items in order when added dynamicly after 3rd item added

I have a button that says ADD ITEM.
Below there is a RECYCLERVIEW.
When you click on ADD ITEM it adds an EDITVIEW to the recycler view. You type text in it, and then click on ADD ITEM again and it adds another EDITVIEW to the recyler view.
Everything is in the right order.
When you click on ADD ITEM for the 4th time, instead of adding at the 4th position, it adds at the 1st position and moves the previous 3 items down 1.
What could be causing this?

Just try to replace your below snippet
myList.add(mLog);
mRecyclerAdapter.notifyData(myList);
etTitle.setText("");
Add this:
myList.add(mLog);
mRecyclerAdapter.addAll(myList);
mRecyclerAdapter.notifyDataSetChanged();
etTitle.setText("");

I would like to see your layout activity_main and recycler_view item because I have tried implementing your code with few twist and the code is working well please check the code below
https://github.com/muchbeer/StackOverflowRecyclerView
Please find the below Screen Shot
Kindy let me if this was your intended application

You are not setting the values for the new views created. Your getView body should look like this:
if (convertView == null) {
convertView = View.inflate(context, R.layout.problem_list, null);
} else {
ImageView img = convertView.findViewById(R.id.problem_imageView);
TextView txtView_Eng =
convertView.findViewById(R.id.englishName_textView);
//TextView txtView_Amc =
convertView.findViewById(R.id.amharicName_textView);
TextView txtView_Count =
convertView.findViewById(R.id.count_textView);
img.setImageResource(listID.get(position));
txtView_Eng.setText(English_Title.get(position));
txtView_Amc.setText(Amharic_Title.get(position));
txtView_Count.setText(count.get(position));
}
return convertView;

How to add Listeners of Dynamic Check Boxes in Simple Adapter

I have dynamic CheckBoxes and now I want to check which CheckBox clicked or not
AdditionalInformation.Java File Here Simple Adapter is defined :
package com.example.ahmad.cvbuilder21;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.Gravity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.CheckBox;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.TextView;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
public class AdditionalInformation extends ActionBarActivity {
CheckBox cb;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_additional_infromation);
cb=(CheckBox)findViewById(R.id.additionalchk);
ABC s = ABC.getSingletonObject();
String[][] str = s.getString();
ListView lv=((ListView)findViewById(R.id.additionallist));
String[] additionalOptions={"Add your Picture","Add Experince / Project","Add Reference","Add Skills / Languages"};
String[] txtViewNames={"options"};
List<HashMap<String,String>>list=new ArrayList<HashMap<String, String>>();
for (int i = 0; i < additionalOptions.length; i++) {
HashMap<String, String> map= new HashMap<String, String>();
map.put("options", additionalOptions[i]);
list.add(map);
}
SimpleAdapter simpleAdpt = new SimpleAdapter(this, list, R.layout.mylayout2,txtViewNames , new int[] {R.id.additionaltxt1});
lv.setAdapter(simpleAdpt);
}
public void additionalData(View view1)
{
if(cb.isChecked())
{
cb.findViewById(R.id.additionalchk).setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View view)
{
Toast toast = Toast.makeText(getApplicationContext(), "Checked",
Toast.LENGTH_SHORT);
toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);
toast.show();
}
}
);
}
else{}
}
}
AdditionalInformation.xml file: where additionalData function is called to
check which CheckBox clicked.
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Choose Additional Options:"
android:id="#+id/additionalBtn"
/>
<ListView
android:layout_below="#id/additionalBtn"
android:layout_centerHorizontal="true"
android:id="#+id/additionallist"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></ListView>
<Button
android:layout_below="#id/additionallist"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add to CV"
android:onClick="additionalData"
/>
</RelativeLayout>
mylayout2.xml file where I define the controls for simple adapter:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<TextView
android:layout_alignParentLeft="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/additionaltxt1"
/>
<CheckBox
android:layout_alignParentRight="true"
android:layout_alignRight="#id/additionaltxt1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="false"
android:id="#+id/additionalchk"
/>
</RelativeLayout>

What you actually need to do is create a custom adapter. In that custom you could listen for checkbox event at the right position.
Here is an example:
public class ListEmployeesAdapter extends BaseAdapter {
public List<Employees> items;
Context c;
public ListEmployeesAdapter(Context c, List<Employees> items) {
this.c = c;
this.items = items;
}
#Override
public int getCount() {
return items.size();
}
#Override
public Object getItem(int position) {
return items.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
c.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.employee_item, null);
}
TextView name = (TextView) convertView.findViewById(R.id.name);
name.setText(items.get(position).name);
name.setOnCLickListener(new OnClickListener(){
#Override
public void onClick(){
//listen to the click
}
});
return convertView;
}
}
Just replace the the layout with you layout and call checkbox instead of TextView and you are good to go.
