list of items only filling first one

I created a custom adapter to fill the item i have depending on how many elements there is but it only fills the first item and i can't figure out why

is there something missing or something doing wrong?

All seems to be ok, but I would change what is on the method getView() by this:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) MainActivity.this.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.item, parent, false);
CustomClass customClass = lst_stuff.get(position);
((TextView) rowView.findViewById(R.id.item_text_1)).
setText(customClass.getTxt1());
((TextView) rowView.findViewById(R.id.item_text_2)).
setText(customClass.getTxt2());
((TextView) rowView.findViewById(R.id.item_text_3)).
setText(customClass.getTxt3());
return rowView;
}
I think that you must obtain first a instance of inflater, and then inflate your view (rowView) with your layout (R.layout.item).
Good luck!

How can i put images in a listView?

I have a ListView but I can´t put images on it.
The error is in Activity_listView at holder.image.setImageDrawable(datos[position].getImage());
The error message is
The method setImageDrawable(Drawable) in the type ImageView is not applicable
for the arguments (ImageView)
Any idea for solve this?

android:layout_height="match_parent" >
<ListView android:id="#+id/LstOpciones"

The class for get values (Puntuacion)
package com.simarro.asteroids;
import android.graphics.drawable.Drawable;
import android.widget.ImageView;
public class puntuacion
{
private ImageView image;
private String jugador;
private String puntuacion;
public puntuacion(ImageView img, String tit, String sub){
image=img;
puntuacion = sub;
jugador = tit;
}
public ImageView getImage(){
return image;
}
public String getJugador(){
return jugador;
}
public String getPuntuacion(){
return puntuacion;
}
}

Instead of returning ImageView in getImage(), return a Drawable and change it to
public Drawable getImage() {
return image.getDrawable();
}
getDrawable() Docs
As the error says, the method setImageDrawable() takes a Drawable type but you are passing it an ImageView

Android GridView flip animation on each cell?

I am fairly new to android development and i'm creating a few simple applications for myself.
I have ran into a problem in relation to animations, in particular a flip animation on each individual cell of a gridview when that cell is clicked.
What my application does so far is retrieves the contacts from the phone and displays the contact photo and the name in a gridview using an array adapter.
What i want to happen is when the user clicks on the grid cell of a contact it will perform a flip animation and display the contacts phone number on the back.
When the user clicks on that cell again it will flip back to the previous view of the name and photo.
I have searched the internet and tried a few tutorials but none that have been of any great help, must of them infact confuse me, so if someone could help that would be great.
I'll post my current code below!
Thanks in advance.
This code is used to retrieve the information of the contacts!
package content;
import android.provider.MediaStore.Images;
public class ContactBean {
private String name;
private String phoneNo;
private String proPic;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhoneNo() {
return phoneNo;
}
public void setPhoneNo(String phoneNo) {
this.phoneNo = phoneNo;
}
public String getProPic() {
return proPic;
}
public void setProPic(String proPic) {
this.proPic = proPic;
}

I would go about it something like this.
Let's say this is the layout you're going to inflate in your gridview and it's named view_flipper_layout. Of course you'd have to add all your textview components etc. to either the front or back linearlayout.
<?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="match_parent"
android:orientation="vertical" >
<ViewFlipper
android:id="#+id/my_view_flipper"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/front"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
<LinearLayout
android:id="#+id/back"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/picture"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</ViewFlipper>
</LinearLayout>
Now let's say this is the adapter
public GridAdapter(Activity act, int row, List<ContactBean> items) {
super(act, row, items);
this.activity = act;
this.row = row;
this.items = items;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View view = convertView;
ViewHolder holder;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//here is where you inflate your layout containing your viewflipper
view = inflater.inflate(R.layout.view_flipper_layout, null);
} else {
holder = (ViewHolder) view.getTag();
}
//reference the viewFlipper
ViewFlipper flipper = (viewFlipper) holder.findViewById(R.id.my_view_flipper);
//your front layout should be set to displayed be default
//now you can get get references to your textview or ImageViews contained within the layout
TextView name = (TextView) holder.findViewById(R.id.name);
name.setText("your text");
ImageView picture = (ImageView) holder.findViewById(R.id.picture);
//now you set your onclick and pass it the current viewflipper to control the displayed child
flipper.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View click) {
flipViewFlipper(flipper);
}
});
return view;
}
private void flipViewFlipper(ViewFlipper flipper){
if(flipper.getDisplayedChild() == 0){
flipper.setDisplayedChild(1);
}
else{
flipper.setDisplayeChild(0);
}
}
}
I'm typing this from my head, so just use it as a guide if you attempt to go this way.

Unable to get custom spinner in android

I have followed this link to learn about implementing custom spinner. My requirement is just to get drop down menu on clicking a image, it should be like a drop down menu where in i load contents to the list from backend.
But i thought that sample example posted in the above link would work. but its not giving any list on clicking a image icon.

Display blank item in grid view

On home scree of application, how to display the menu which is similar to android menu but no items needs to be displayed in specific cells. Considering grid of 3 x 3, five items only needs to be displayed at (Row, Col): [0,1], [1,0], [1,1], [1,2], [2,1].
We have tried GridView and set visibility to GONE (convertView.setVisibility(View.GONE);) for items which need not be displayed. Following this, item is not displayed in grid but when user browses through blank item using up and down keys or click directly on blank item, that icon is hihglighted and selected as if it is blank item in grid. We want as it is blank it should not repond to user events neither highlighted not selected.
Code for Grid View:
package org.XXX;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
public class XXXActivity extends Activity {
GridView MyGrid;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.maingrid);
MyGrid = (GridView)findViewById(R.id.MyGrid);
MyGrid.setAdapter(new ImageAdapter(this));
MyGrid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
Toast.makeText(arg0.getContext(), position + " selected", Toast.LENGTH_LONG).show();
switch(position) {
case 0:break;
case 1:
//Browse
Intent newIntent = new Intent(XXXActivity.this, YYYListItemIcons.class);
startActivity(newIntent);

startActivity(newIntent);
break;
case 4:
//Sign in
break;
case 5:
//Reminders
break;
case 6:break;
case 7:

break;
case 8:break;
}
}
});
//onSearchRequested(); //to open search by default
}

LayoutInflater mInflater = LayoutInflater.from(MyContext);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.grid_item, null);
holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById(R.id.grid_item_text);
holder.icon = (ImageView) convertView.findViewById(R.id.grid_item_image);
convertView.setTag(holder);
} else {

}
// Bind the data efficiently with the holder.
holder.text.setText(getTextId(position));
holder.icon.setImageBitmap(BitmapFactory.decodeResource(MyContext.getResources(), getIconId(position)));
if(getIconId(position) == R.drawable.nothing) {

}
return convertView;
}

}
private int getIconId(int position) {

GridLayout:
<GridView xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/GridItem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</LinearLayout>

if(getIconId(position) == R.drawable.nothing) {
convertView.setVisibility(View.GONE);
}
replace the above lines by below and try....
if(getIconId(position) == R.drawable.nothing) {
convertView.setVisibility(View.GONE);
convertView.setClickable(false);
convertView.setEnabled(false);
}
try this code in getview().

Now that you have posted your code, I am not sure if you can technically remove but you can disable the "highlighted" click that you are talking about, this way, when a user clicks on the one of the icons, it will no longer highlight.
This can be done via XML or in your code:
https://stackoverflow.com/questions/2865683/android-disable-highlighting-in-gridview
Code: GridView.setSelector(new ColorDrawable(Color.TRANSPARENT));
XML: android:listSelector="#00000000"
However, this will affect all the icons in your gridview.
Also take a look at this:
