Showing or hiding an object in a listview

Showing or hiding an object in a listview - android

The image in the imageview disappears from the scrollview in the ListView. How can i solve it?
public class IzahAdapter extends BaseAdapter {
private ArrayList<IzahVeriModeli> list;
LayoutInflater layoutInflater;
Context context;
holder Holder;
int pos;
public IzahAdapter(Context context, ArrayList<IzahVeriModeli> list) {
this.context = context;
// Layout Inflater tanımlanıyor...
this.list = list;
}
#Override
public int getCount() {
return list.size();
}
#Override
public Object getItem(int position) {
return list.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
Holder=null;
View satirView = null;
Button bIngg, bTrr;
ImageView resimm = null;
//
if (convertView == null) {
layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.listview_izahat, parent, false);
Holder = new holder();
Holder.resim = (ImageView) convertView.findViewById(resim);
Holder.bIng = (Button) convertView.findViewById(bIng);
Holder.bTr = (Button) convertView.findViewById(bTr);
Holder.bTr.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
pos = (Integer)v.getTag();
list.get(pos).setSelected(false);
System.out.println("pip2 = " + Integer.toString(pos));
notifyDataSetChanged();
}
});
Holder.bIng.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int pos = (Integer)v.getTag();
list.get(pos).setSelected(true);
System.out.println("pip3 = " + Integer.toString(pos));
notifyDataSetChanged();
}
});
convertView.setTag(Holder);
}
else {
Holder = (holder) convertView.getTag();
}
Holder.bTr.setTag(position);
Holder.bIng.setTag(position);
Holder.resim.setTag(position);
System.out.println("pip1 = " + position);
if (list.get(position).isSelected()) {
Holder.bTr.setVisibility(View.VISIBLE);
Holder.bIng.setVisibility(View.GONE);
notifyDataSetChanged();
} else {
Holder.bTr.setVisibility(View.GONE);
Holder.bIng.setVisibility(View.VISIBLE);
notifyDataSetChanged();
}
if (this.list.get(position).getResim()!=null)
{
Holder.resim.setImageBitmap(this.list.get(position).getResim2());
}
else
{
Holder.resim.getLayoutParams().width=0;
}
return convertView;
}
}
The image in Imageview comes from the data base. ImageView is shrinking if it is null, if not it adds image, but when i scroll the listview, things get messed up.
I did a lot of hard work, but i did not get resolved it.

Try something like that:
if (this.list.get(position).getResim()!=null) {
Holder.resim.setVisibility(View.Visible);
Holder.resim.setImageBitmap(this.list.get(position).getResim2());
}
else {
Holder.resim.setVisibility(View.Gone);
Holder.resim.setImageresource(0);
}

Skip Item Android Grid View in condition

I'm trying to build an android application,I have a 3 columns gridview that show a list of points,I want to jump to next line in a condition even when some of the columns are empty
Example I want to do something like this:
ARX ARH
BRH BRX BRY
CRH
DRH DRY

Try this One
your List item Row XML would be like this
Abc.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#android:color/darker_gray">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_margin="5dp">
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_weight="1"
android:gravity="center"
android:text="Name1"
android:textSize="18sp"
android:background="#android:color/white"
android:layout_margin="5dp"/>
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_weight="1"
android:gravity="center"
android:text="Name2"
android:textSize="18sp"
android:layout_margin="5dp"
android:background="#android:color/white"/>
<TextView
android:id="#+id/textView3"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_weight="1"
android:gravity="center"
android:text="Name3"
android:textSize="18sp"
android:layout_margin="5dp"
android:background="#android:color/white"/>
</LinearLayout>
</LinearLayout>
And CustomAdapter for List Would be like this
public class Custom_Adapter_Products extends BaseAdapter {
Context context;
String[] list = {"AAA","AAA","AAA","AAA","AAA","","AAA", "AAA","AAA"};
public Custom_Adapter_Products(Context context){
this.context = context;
}
#Override
public int getCount() {
return (list.length/3);
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int pos, View convertView, ViewGroup parent) {
try{
int position = (pos*3);
ViewHolder holder;
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
{
convertView = vi.inflate(R.layout.abc, null);
holder = createViewHolder(convertView);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
if(!list[position].equals("")){
holder.textView1.setText(list[position]);
holder.textView1.setVisibility(View.VISIBLE);
}
else{
holder.textView1.setVisibility(View.GONE);
}
if(!list[position+1].equals("")){
holder.textView2.setText(list[position]);
holder.textView2.setVisibility(View.VISIBLE);
}
else{
holder.textView2.setVisibility(View.GONE);
}
if(!list[position+2].equals("")){
holder.textView3.setText(list[position]);
holder.textView3.setVisibility(View.VISIBLE);
}
else{
holder.textView3.setVisibility(View.GONE);
}
}catch (Exception e){
e.printStackTrace();
}
return convertView;
}
private static class ViewHolder
{
public TextView textView1;
public TextView textView2;
public TextView textView3;
}
private ViewHolder createViewHolder(View v) {
ViewHolder holder = new ViewHolder();
try{
holder.textView1 = (TextView) v.findViewById(R.id.textView1);
holder.textView2 = (TextView) v.findViewById(R.id.textView2);

Android ListView displays only first element of List<string passed to it

public class MyAdapter extends BaseAdapter implements ListAdapter {
private List<String> events = new ArrayList<String>();
private Context context;
public MyAdapter(List<String> events, Context context) {
this.events = events;
this.context = context;
String a = String.valueOf(events.size());
Toast.makeText(context,a,Toast.LENGTH_LONG).show();
}
#Override
public int getCount() {
return events.size();
}
#Override
public Object getItem(int position) {
return events.get(position);
}
#Override
public long getItemId(int position) {
//return events.get(position).getId();
return 0;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = layoutInflater.inflate(R.layout.list_item_layout, null);
}
TextView listtv = (TextView) view.findViewById(R.id.label1);
listtv.setText(events.get(position));
Button delbutton = (Button) view.findViewById(R.id.del_button);
delbutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context,"You didn' code this feature yet",Toast.LENGTH_LONG).show();
}
});
return view;
}
}
I am creating an object of MyAdapter and calling it by passing a List and Activity.this
when i try to toast the size of the list passed i get the proper size
however only the first item of the list gets displayed on the screen

Focus on wrong edit text inside listview

When I try to click on EditText inside ListView item. It gains focus and loses focus, while debugging I found that if I clicked on 21st item, the position value changed like 21, 19, 1, 2 etc. Not sure if the list is re-rendering itself or something else is happening. I have already searched a lot and already tried configuring ListView (beforeDescendants and afterDescendants) and Activity (adjustPan).
I have used my custom adaptor. Sharing the XML file of ListView and list item along with java code of adapter.

Thanks in advance.

Insert this Line in onCreate before setContentView()
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_MASK_ADJUST);
It will definitely help you

Finally, I figured it out. the problem was trying to solve get tex changed value inside getview. This was re-rendering the list items and I was getting wrong focus and different weird behavious. I have created a textwatcher class and added it while initializing the object, so that it doesn't affect everytime for each item in the list. Below is the code for MyCustom Adapter

2)how to refresh view in this code by clearing all checkboxes when a button is clicked.

Showing or hiding an object in a listview - android

Try something like that: if (this.list.get(position).getResim()!=null) { Holder.resim.setVisibility(View.Visible); Holder.resim.setImageBitmap(this.list.get(position).getResim2()); } else { Holder.resim.setVisibility(View.Gone); Holder.resim.setImageresource(0); }
