问题
let's say that i have a list of items and i want to build a form with each of these items. This form consist of two checkboxes and an editText. For example i want to know if each item is present in a warehouse and its quantity. I'm thinking for solving my problem to use a listview where each element of my listview will consist of the name of an item, two checkboxes and an editText.
The problem is that the only use of listview i know to present list of elements, i don't how to solve my problem with it (i'm a beginner in android). Can someone help me ?
Is there another way to solve my problem ?
Thank you

Try to implements a cusom ListView adapter! This is easier than you might think!
First you need to create layout which would will represent each item in your list:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Test TEST" />
<LinearLayout android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignBottom="@id/itemTextView"
android:layout_alignParentRight="true">
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/doneCheckBox" />
</LinearLayout>
Then implement cusom adapter inside your code:
public CusomAdapter(Context mainContex, YourItems<SomeItem> someItems) {
this.mainContex = mainContex;
this.someItems = someItems;
}
@Override
public int getCount() {
return someItems.size();
}
@Override
public Object getItem(int position) {
return someItems.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View item = convertView;
if (item == null) {
item = LayoutInflater.from(mainContex).inflate(R.layout.shoplist_item, null); // your listView layout here!
}
//fill listView item with your data here!
//initiate your check box
CheckBox doneCheckBox = (CheckBox)item.findViewById(R.id.doneCheckBox);
//add a checkbox listener
doneCheckBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
doneCheckBox.ischecked=true;
}
else{
doneCheckBox.ischecked=false;
}
}
});
return item;
}
don't forget to add ListView element inside your Activity layout!
