Edittext in listview android example

Here I have written simple step to create Listview with edittext .Please follow the step to do this task.

Step1 :

Create simple main.xml with listview and set listview properties for the fast listview scrolling.

<ListView

android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:animationCache="false"
android:scrollingCache="false"
android:smoothScrollbar="true" >

</ListView>

Step 2:

Create ArrayList add data into the arraylist.

lv=(ListView)findViewById(R.id.listView1);
lv.setItemsCanFocus(true);

for(int i=0;i<30 data-blogger-escaped-br="" data-blogger-escaped-i=""> list.add(i);
}

Step 3:

1)create adapter for the listview and set the position as tag for the edittext.

2)Normally,when scrolling the item position will change.So,you have to get the edittext tag and set it into the edittext id.from that you can avoid the change of the item position.

holder.caption = (EditText) convertView
.findViewById(R.id.editText12);
holder.caption.setTag(position);
holder.caption.setText(list.get(position).toString());
convertView.setTag(holder);

}else {
holder = (ViewHolder) convertView.getTag();
}
int tag_position=(Integer) holder.caption.getTag();
holder.caption.setId(tag_position);

Step 4:

Finally,add the text watcher to the edittext and store the changes into correct position in the list.

holder.caption.addTextChangedListener(new TextWatcher() {

@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
final int position2 = holder.caption.getId();
final EditText Caption = (EditText) holder.caption;
if(Caption.getText().toString().length()>0){
list.set(position2,Integer.parseInt(Caption.getText().toString()));
}else{
Toast.makeText(getApplicationContext(), "Please enter some value", Toast.LENGTH_SHORT).show();
}

}

@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}

@Override
public void afterTextChanged(Editable s) {

}

});

kabil dev said...: You have to use your Own view and Save your view while scrolling... Like

private Map myViews = new HashMap();

@Override
public View getView(final int position, View convertView, ViewGroup parent) {

View view = myViews.get(position);
if (view == null) {

myViews.put(position, view);
