is there any code to declare the imageview and set imageresource without inflate the layout ?
i am create listview adapter in other layout, so i didnt inflate the layout.
but ineed to set image to the imageview.
this is my code but its not working
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_item_list_request, container, false);
setHasOptionsMenu(true);
rlRequestWorkflow = (RelativeLayout)getActivity().findViewById(R.id.rlListRequestWorkflow);
listPhoto = (ImageView)getActivity().findViewById(R.id.listPhoto);
rlRequestWorkflow.addView(listPhoto);
}
this is my current layout (main class)
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/flRequest"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
tools:context="com.ITK.SMP.Native.Workflow.ListRequest">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice"
android:background="#ffffff">

android:id="#+id/lvRequest"
android:choiceMode="singleChoice"
android:nestedScrollingEnabled="false"
/>
</android.support.v4.widget.SwipeRefreshLayout>
</RelativeLayout>
this is listadapter class
public class ListRequestAdapter extends ArrayAdapter<ListRequestItem> {
ImageView listPhoto;
public ListRequestAdapter(Context context, List<ListRequestItem> items)
{
super(context, R.layout.style_fragment_list_request, items);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if(convertView == null) {
// inflate the GridView item layout
LayoutInflater inflater = LayoutInflater.from(getContext());
convertView = inflater.inflate(R.layout.style_fragment_list_request, parent, false);
// initialize the view holder
viewHolder = new ViewHolder();
viewHolder.tvTanggal = (TextView) convertView.findViewById(R.id.tvTanggalRequest);
viewHolder.tvTipe = (TextView) convertView.findViewById(R.id.tvTipeRequest);
viewHolder.tvStatus = (TextView) convertView.findViewById(R.id.tvStatus);
viewHolder.permitid = "";
convertView.setTag(viewHolder);
} else {
// recycle the already inflated view
viewHolder = (ViewHolder) convertView.getTag();
}
// update the item view
ListRequestItem item = getItem(position);
viewHolder.tvTanggal.setText(item.tanggal);
viewHolder.tvTipe.setText(item.tipe);
viewHolder.tvStatus.setText(item.status);
viewHolder.permitid = item.permitid;
return convertView;
}
private static class ViewHolder {
TextView tvTanggal;
TextView tvTipe;
TextView tvStatus;
String permitid;
}
}
this is the imageview in the listadapterlayout

any help would be appreciated
If you don't want to inflate your imageview, then pass your imageview in the constructor of class, and set the image from there.
Suppose, MainActivity is the class where your image view is present
MainActivity.class
ImageView imageview;
imageview=(ImageView)findViewById(R.Id.imageview);
new ListAdapter(imageview);
ListAdapter.class
ImageView imageview;
//constructor
public ListAdapter(ImageView imageview){
this.imageview=imageview;
}
//now you can use imageview to set image
Edit this:-
rlRequestWorkflow = (RelativeLayout)view.findViewById(R.id.rlListRequestWorkflow);
listPhoto = (ImageView)view.findViewById(R.id.listPhoto);

I was using listView without with the custom layout which is having
Linear layout as parent layout. Scrolling was fine, Then I need to

list Scrolling become slow.Moreover it is also slowing down the

Cardview is probably just the "breaking point" for how much graphic content that cna be used in an unoptimized way without lagging. As mentioned in some comments you should be using a ViewHolder, here is a simple example of using a viewholder:
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_entry, null);
holder = new ViewHolder();
holder.nameTextView = (TextView) convertView.findViewById(R.id.person_name);
holder.surnameTextView = (TextView) convertView.findViewById(R.id.person_surname);
holder.personImageView = (ImageView) convertView.findViewById(R.id.person_image);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
Person person = getItem(position);
holder.nameTextView.setText(person.getName());
holder.surnameTextView.setText(person.getSurname());
//holder.personImageView.setImageBitmap(person.getImage());
return convertView;
}
you can read more about it here
Additionally you should be using RecyclerView and not ListView, to optimize performance.
Try to minimize your view hierarchy and reduce complex operations from binding.
I'm trying to implement a custom list view which has list items with spinner and edittext. And the list item needs to be selectable, also the edittext in list item needs to be editable. But the problem is when I set the edittext editable with setFocusable(true), the list item isn't selectable, and when I set the edittext not editable with setFocusable(false), the list item is selectable. Does anyone know how to solve this?
Below is my code
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View listItemView = convertView;
if (listItemView == null) {
listItemView = inflater.inflate(R.layout.listitem, null);
ViewHolder viewHolder = new ViewHolder();
viewHolder.view1 = (Spinner) listItemView.findViewById(R.id.view1);
viewHolder.view2 = (EditText) listItemView.findViewById(R.id.view2);
viewHolder.view1.setFocusable(false);
viewHolder.view2.setFocusable(false);
viewHolder.view1.setAdapter(view1Adapter);
viewHolder.view1.setOnItemSelectedListener(this);
viewHodler.view2.setOnFocusChangeListener(this);
listItemView.setTag(viewHolder);
}
CustomListItem item = listViewItemList.get(position);
ViewHolder viewHolder = listItemView.getTag();
viewHolder.view1.setSelection(item.view1Value);
viewHolder.view1.setTag(item);
viewHolder.view2.setText(item.view2Value);
viewHolder.view2.setTag(item);
return listItemView;
}
===== updated to add xml =====
Below is my xml files for list view and item.
For list view.

Finally I found a solution for this requirement, however it requires a bit code works and it was different with what I expected at first.
Anyway below is a code block from my list adapter which implements AdapterView.OnItemSelectedListener, View.OnFocusChangeListener and View.OnTouchListener
private EditText activatedEditText;
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View listItemView = convertView;
if (listItemView == null) {
listItemView = inflater.inflate(R.layout.listitem, null);
ViewHolder viewHolder = new ViewHolder();
viewHolder.view1 = (Spinner) listItemView.findViewById(R.id.view1);
viewHolder.view2 = (EditText) listItemView.findViewById(R.id.view2);
viewHolder.view1.setFocusable(false);
viewHolder.view2.setFocusable(false);
viewHolder.view1.setOnTouchListener(this);
viewHolder.view2.setOnTouchListener(this);
viewHolder.view1.setAdapter(view1Adapter);
viewHolder.view1.setOnItemSelectedListener(this);
viewHodler.view2.setOnFocusChangeListener(this);
listItemView.setTag(viewHolder);
}
CustomListItem item = listViewItemList.get(position);
ViewHolder viewHolder = listItemView.getTag();
viewHolder.view1.setSelection(item.view1Value);
viewHolder.view1.setTag(item);
viewHolder.view2.setText(item.view2Value);
viewHolder.view2.setTag(item);
return listItemView;
}
#Override
public boolean onTouch(View v, MotionEvent event) {
if(v.getClass() == EditText.class) {
activatedEditText = (EditText)v;
activatedEditText.setFocusable(true);
activatedEditText.setFocusableInTouchMode(true);
activatedEditText.requestFocus();
}
else {
activatedEditText.clearFocus();
activatedEditText.setFocusable(false);
activatedEditText.setFocusableInTouchMode(false);
InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(activatedEditText.getWindowToken(), 0);
}
}
Im an android newbie so please forgive me...
This is my code:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if (convertView == null) {
viewHolder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.adapter_who_row, null);
viewHolder.nameTextView = (TextView) convertView.findViewById(R.id.text);
viewHolder.companyTextView = (TextView) convertView.findViewById(R.id.whoRowCompany);
viewHolder.dotView = convertView.findViewById(R.id.whoRowDot);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
String textToShow = dataArray.get(position);
viewHolder.nameTextView.setText(textToShow);
viewHolder.dotView.setBackgroundColor(getResources().getColor(R.color.red));
viewHolder.companyTextView.setText("Test");
return convertView;
}
class ViewHolder {
TextView nameTextView;
TextView companyTextView;
View dotView;
}
dotView doesn't change its colour...
However, the two textVies does change their text.
What could it be?
Edit:
The xml is holding two editTexts and one View.
Below is my xml:

remove this line from your xml view and try:
android:backgroundTint="#color/noteColor"
Above is the main screen of my app with a custom adapter for listview. How do I put a different icon for each row in the listview? I tried putting an ImageView in the xml but it overwrites my whole screen only showing an icon.

Your list.xml should be something similar to this (taken from one my files)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:gravity="center_vertical" android:orientation="horizontal"
android:background="#drawable/xml_pressed_bg" android:clickable="true" android:layout_width="fill_parent"

android:src="#drawable/sample_dj" />
<TextView android:textSize="14.0sp" android:textColor="#ff666666" android:id="#+id/txtName"
android:layout_width="180dip" android:layout_height="wrap_content"
android:singleLine="true" android:shadowColor="#99ffffff" style="#style/TextShadowLight"
android:text="Hello" android:paddingLeft="10dip"/>
</LinearLayout>
Every row item has an image (imgThumb). This needs to be changed or set to a static image, depending on your needs. This is done in the adapters' getView() method.
imgThumb.setImageResource(R.drawable.my_image);
Private TypedArray img;
img=getResource.obtainTypedArray(R.array.imgIcon)
if (sa[position].startsWith("Air pressure")) {

in this adapter i want to manipulate the view of linearlayouts by having LinearLAyout.setVisibility(LinearLayout.GONE or VISIBLE);
Here i think i have some lead from my problem from the answer of himanshu. here is my listview special adapter im having problem how can get the view and viewGroup implementation to my special adapter here is my SpecialAdapter..
public class SpecialAdapter extends SimpleAdapter {
public static TextView tv;
private int[] colors = new int[] { 0xffcccccc , 0xffffffff };
private int[] colors2 = new int[] { 0xffffffff , 0xff000000 };
// Context context;
public SpecialAdapter(Context context, List<HashMap<String, String>> items, int resource, String[] from, int[] to) {
super(context, items, resource, from, to);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
int colorPos = position % colors.length;
view.setBackgroundColor(colors[colorPos]);
//TextView textView = (TextView)view.findViewById(R.id.textViewModAmountCheck);
//textView.setText("AlvinTest");
return view;
}
Could anyoune tell me i am doing right when im implementing mg getView2.
public View getView2(Context context, int position, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater = LayoutInflater.from(context);//get your layout inflator;
//LayoutInflater inf = LayoutInflater.from(getContext());
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.listview_layout, null);
}
LinearLayout yyy = (LinearLayout) convertView.findViewById(R.id.linearCheckDate);
yyy.setVisibility(View.GONE);
return convertView;
}
public boolean setViewValue(View view, Cursor cursor, int columnIndex){
int getIndex = cursor.getColumnIndex("Name");
String empname = cursor.getString(getIndex);
tv = (TextView) view;
tv.setTextColor(Color.WHITE);
tv.setText(empname);
if(empname.equals("Any String"))
{
tv.setTextColor(Color.rgb(58, 58, 224));
return true;
}
return false;
}
}
Here's my code when im calling the getView2 from my listAdapter
LayoutInflater inf = LayoutInflater.from(this);
View v = inf.inflate(R.layout.listview_layout, null);
//add magic here bu i don't know how can i get the view of these View and ViewGroup
View itemConvertView = inf.inflate(R.layout.listview_layout, null);
ViewGroup listParent =null; //this.getParent();//(ViewGroup)SelectorView.this.getParent();// null;
adapterListView.getView2(this,0, itemConvertView, listParent);
try this:
Hide your Layout:
YourLayout.setVisibility(View.GONE);
Visible your Layout :
YourLayout.setVisibility(View.VISIBLE);
If i understood your problem correctly, you want to get the first element of the ListView pro grammatically and change its state (Visibility).
You can get the element in ListView by calling getChildAt(int index) method
e.g
LinearLayout yourFirstView = (LinearLayout) listview.getChildAt(0);
Accessing child of the element that reside in first row of the listview.
ViewType view = (ViewType)yourFirstView.findViewById(R.id.elementId);
setting the visiblity
yourFirstView.setVisiblity(View.Gone); // or View.VISIBLE
What I understand from your question is that there is some view in your ListView item which you want to show only if needed. You can do this in the getView method of your adapter where you inflate the custom layout of list item. Something like below
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater layoutInflater = get your layout inflator;
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.XXXX, null);
}
LinearLayout yyy = (LinearLayout) convertView.findViewById(R.id.member_name_text_view);
yyy.setVisibility(View.Gone)
return convertView;
}
