i will use like that..
public class list extends Activity {
private ListView list;
private Button add ;
private Dialog dialog;
private ListViewAdapter adapter;
private ArrayList<String> listData;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

add.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {

}
});
list.setAdapter(adapter);
}
public void AddSMS(){
dialog = new Dialog(this);
dialog.setContentView(R.layout.popup1);
dialog.setTitle("Add Your SMS");
final EditText et = (EditText)dialog.findViewById(R.id.editText11);
Button close = (Button)dialog.findViewById(R.id.btn_clss);
close.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
Button save = (Button)dialog.findViewById(R.id.btn_svv);
save.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (et.getText().toString().trim().length()>0){
listData.add(et.getText().toString());
adapter = new ListViewAdapter(list.this, listData);
list.setAdapter(adapter);
dialog.dismiss();
}else {
et.setError("Value Required");
}
}
});
dialog.show();
}
class ListViewAdapter extends BaseAdapter {
private Context context;

this.context = context;
this.data = data;

filterData.addAll(this.data);
}
public class ViewHolder {

}
#Override

}

}
public View getView(final int position, View view, ViewGroup parent) {
final ViewHolder holder;
if (view == null) {
holder = new ViewHolder();
view = LayoutInflater.from(context).inflate(R.layout.list_double, null);
holder.txttt = (TextView) view.findViewById(R.id.txttt);

}else{
for (String Detail : data){
if (Detail.toLowerCase().contains(charText.toLowerCase())){
filterData.add(Detail);

}
notifyDataSetChanged();
}
}
}

instead of add to list add the item in adapter and then call notifyDataSetChanged

Focus with order editTexts in listview

My app is barcodeReader which user read to barcodeID set it Textview and he can enter the number of product in editText.I implement in listview which include textview and editText. When user scan to barcodeNumber, i set to it on textView and but i want after set to text automatically focus the edit text in order .How can i do that?
Edit!!
I already add to request focus on but always focus on 1. editText and when 2. Barcode scanned 1.editText value again take "0";
This is my listView;
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/ID"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="3"
android:ellipsize="end"
android:padding="5dp"
android:singleLine="true" />
<EditText
android:id="#+id/Quantity"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ellipsize="end"
android:padding="5dp"
android:singleLine="true"
android:inputType="number">
<requestFocus />
</EditText>
</LinearLayout>
This is my adapter;
public class ListViewAdapter extends BaseAdapter {
public ArrayList<Model> productList;
Activity activity;
public ListViewAdapter(Activity activity, ArrayList<Model> productList) {
super();
this.activity = activity;
this.productList = productList;
}
#Override
public int getCount() {
return productList.size();
}
#Override
public Object getItem(int position) {
return productList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
private class ViewHolder {
TextView ID;
EditText Quantity;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
LayoutInflater inflater = activity.getLayoutInflater();
if (convertView == null) {
convertView = inflater.inflate(R.layout.listview_row, null);
holder = new ViewHolder();
holder.ID = (TextView) convertView.findViewById(R.id.ID);
holder.Quantity = (EditText) convertView.findViewById(R.id.Quantity);;
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
Model item = productList.get(position);
holder.ID.setText(item.getID().toString());
holder.Quantity(String.valueOf(item.getQuantity()));
return convertView;
}
}
And here is the Activity;
public class BarcodeReaderActivity extends AppCompatActivity {
Button btnBarcodeReader;
EditText Quantity;
private ArrayList<Model> mlist;
Model item;
ListViewAdapter adapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_barcodereader);
mlist= new ArrayList<Model>();
ListView lview = (ListView) findViewById(R.id.listview);
adapter = new ListViewAdapter(this, mlist);
QuantityRowID = findViewById(R.id.Quantity);
lview.setAdapter(adapter);
btnBarcodeReader = (Button)findViewById(R.id.btnBarcodeReader);
adapter.notifyDataSetChanged();
final Activity activity = this;
btnBarcodeReader.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(activity);
integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
integrator.setPrompt("Scan");
integrator.setCameraId(0);
integrator.setBeepEnabled(false);
integrator.setBarcodeImageEnabled(false);
integrator.initiateScan();
}
});
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Log.d("MainActivity", "Cancelled scan");
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Log.d("MainActivity", "Scanned");
//Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
populateList(result.getContents());
}
} else {
// This is important, otherwise the result will not be passed to the fragment
super.onActivityResult(requestCode, resultCode, data);
QuantityRowID.requestFocus();
int val = Integer.parseInt( QuantityRowID.getText().toString() );
item.Quantity=val;
QuantityRowID.setText(val);
adapter.notifyDataSetChanged();
}
}
public void populateList(String ID){
item = new Model(ID,0);
mlist.add(item);
adapter.notifyDataSetChanged();
}
}

Just simply set request focus on your EditText after setting all view like
//your other view like textview and imageview if you have
Quantity.requestFocus();

Try this code..
edittextbox.requestFocus();
and xml code..
<EditText ...>
<requestFocus />
</EditText>

In your Adapter getView() method write this
holder.ID.addTextChangedListener(new TextWatcher() { #Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
#Override
public void afterTextChanged(Editable s) {
holder.Quantity.requestFocus();
}
});

This is a workaround, it will forcefully show the keyboard to targeted editText.
InputMethodManager keyboard = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
keyboard.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);

Try this:
public void populateList(String ID){
item = new Model(ID,0);
mlist.add(item);
adapter.notifyDataSetChanged();
ListView listView = (ListView) findViewById(R.id.listview);
listView.smoothScrollToPosition(mlist.size() - 1);
LinearLayout childView = (LinearLayout)listView.getChildAt(listView.getLastVisiblePosition() - listView.getFirstVisiblePosition());
EditText quantity = (EditText)childView.findViewById(R.id.Quantity);
quantity.requestFocus();
}
Hope it helps!!

I want to remove List element on Click of Delete Button or toggle the status of task with checkBox,I'm not even seeing the Toast that is present in clickListener of Checkbox and Delete Button,there's just nothing happening, unable to figure out how to do that..

Make a Callback interface to solve your problem. I think this the best way what you want to achieve.
OnItemClickListener
public class OnItemClickListener implements View.OnClickListener {
private int position;
private OnItemClickCallback onItemClickCallback;
public OnItemClickListener(int position, OnItemClickCallback
onItemClickCallback) {
this.position = position;
this.onItemClickCallback = onItemClickCallback;
}
#Override
public void onClick(View view) {
onItemClickCallback.onItemClicked(view, position);
}
public interface OnItemClickCallback {
void onItemClicked(View view, int position);
}
}
In your adapter class
private OnItemClickListener.OnItemClickCallback onItemClickCallback;
public CustomAdapter(#NonNull Context context, ArrayList<listClass> arr,
OnItemClickListener.OnItemClickCallback onItemClickCallback)
{
super(context,R.layout.detail, arr);
this.arr = new ArrayList<listClass>(0);
this.onItemClickCallback = onItemClickCallback;
this.arr.addAll(arr);
}
and
holder.imageButton.setOnClickListener(new OnItemClickListener(position,
onItemClickCallback));
In your activity
private OnItemClickListener.OnItemClickCallback
onItemDeleteClickCallback = new
OnItemClickListener.OnItemClickCallback() {
#Override
public void onItemClicked(View view, int position) {
//here you will get delete item pos
}
};
and
CustomAdapter adapter = new CustomAdapter(MainActivity.this, arr,
onItemDeleteClickCallback );
final ListView lv = findViewById(R.id.vishulv);
lv.setAdapter(adapter);
Hope this will help you.

Try this in your adapter
holder.checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (buttonView.isChecked()) {
//checked
Toast.makeText(getContext(),"active checkbox",Toast.LENGTH_LONG).show();
}
else
{
//not checked
Toast.makeText(getContext(),"inactive checkbox",Toast.LENGTH_LONG).show();
}
});

i tried add this code to see if my code run with correctly then the toast will be show but i got error;
i got this error
i am trying to create a baseadapter..
package com.example.test;
import java.util.ArrayList;

import java.util.Map;

return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater lif = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = lif.inflate(R.layout.listitem, null);
TextView txt_Name = (TextView) convertView.findViewById(R.id.varId);
Button btnEdit = (Button) convertView.findViewById(R.id.btnEdit);
btnEdit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("mybutton in listview already works!!");
//Here perform the action you want
}
});
return convertView;
}
}

Try to use BaseAdapter Instead of ListAdapter it will be easier
Here i'm giving sample code you can implement like this in your code,
public class BaseAdapContact extends BaseAdapter {
List<String> liName;
Context con;
public BaseAdapContact(List<String> liName, Context con) {
this.liName = liName;
this.con = con;
}
#Override
public int getCount() { // TODO Auto-generated method stub
return liName.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater lif = (LayoutInflater) con
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = lif.inflate(R.layout.list_view, null);
TextView txt_Name = (TextView) convertView.findViewById(R.id.txtName);
Button btn_Call = (Button) convertView.findViewById(R.id.btnCall);
txt_Name.setText(liName.get(position));
btn_Call.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//Here perform the action you want
}
});
return convertView;
}
}

As per my aspect you should initialized your list in setUpView();
list = (ListView) findViewById(R.id.list);
Your app is crash at
list.invalidateViews();
list.setAdapter(adapter);
in onPostExecute(Void result) at this line list==null

Where is your list adapter???
You should set onClickListner on a button inside your list adapter

you should use interface to listen Click Event.
Here is example,
First, you need to create a interface in adapter.
public interface onListItemClickListener{
void onEditClick();
void onDeleteClick();
}
And then implement onListItemClickListener in your registerItem activity. It will need to implement two methods in your activity.
in click event from your adapter, for ex
btn_edit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//you will contain Context from your parent activity
//cast your context to listener coz it implement that listener
onListItemClickListener listener = (onListItemClickListener) mContext;
// you can add parameter in method
listener.onEditClick();
//Done this will call your method in your activity.
}
});
Hope this will help you.

adapter.notifyDataSetChanged();
wishEditText.setText("");
InputMethodManager inputMethodManager = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(wishEditText.getWindowToken(), 0);
Toast.makeText(getBaseContext(), "New wish Added To List", Toast.LENGTH_SHORT);
}
});
};
}
Please help me.
When I pressed OK button then my apps has stop but there is no error even eclipse do't show any error.
How I can solve it?
Please help me.

This like inputMethodManager.hideSoftInputFromWindow(wishEditText.getWindowToken(), 0); might be giving you a NullPointerException

Try this way,hope this will help you to solve your problem.
