imageView.setImageResource(imageAdapter.getItemViewType(position));}}
can anyone help me
Two points:
Pass the URL of the image you selected from MainActivity to SingleViewActivity.
Use ImageLoader, and do not modify the width/heigth otherwise the memory cache will miss.
Others the cache will do everything for you.
Sorry for my english. There is a mini-gallery, when you click on an image from the gallery it should (picture) to open in full screen. App just throws by pressing the image. what am I doing wrong?

}
}
clean you project if it does not work
imageView.setLayoutParams( new ViewGroup.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT));
change it to
imageView.setLayoutParams( new LinearLayout.LayoutParams(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT));
I'am new to android and I've a project of making a grid view of images and onclick on image it shows it , thats the ImageAdapter class code
public class ImageAdapter extends BaseAdapter{
private static LayoutInflater inflater = null;
private Activity activity;
private String mode = "";
int[] images=null ;
public ImageAdapter(Activity act, String mode , int[] images){
inflater = (LayoutInflater) act.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
activity = act;
this.mode = mode;
this.images= images ;
}
public ImageView getImage(int pos)
{
ImageView im = (ImageView) getItem(pos);
return im ;
}
#Override
public int getCount() {
return images.length;
}
#Override
public Object getItem(int position) {
return new Integer(images[position]);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View view, ViewGroup parent) {
if(mode.equalsIgnoreCase("grid")){
if (view == null) {
view = inflater.inflate(R.layout.each_image1, null);
}
ImageView iv = (ImageView)view.findViewById(R.id.imageView);
iv.setImageResource(images[position]);
} else if(mode.equalsIgnoreCase("gallery")){
if (view == null) {
view = inflater.inflate(R.layout.each_image_gallery, null);
}
ImageView iv = (ImageView)view.findViewById(R.id.imageView);
iv.setImageResource(images[position]);
}
return view;
}
}
thats my grid activity
public class GridActivity extends Activity {
GridView grid = null;
public static ImageAdapter adapter1 ;
public static ImageAdapter adapter2 ;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.grid);
adapter1= new ImageAdapter(GridActivity.this, "grid" , Images.images1);
adapter2 = new ImageAdapter(GridActivity.this, "grid" , Images.images2);
Intent i = this.getIntent();
if (i!=null)
{
String unique = i.getExtras().getString("Unique");
if (unique.equals("islam"))
{
Toast.makeText(GridActivity.this, "islam", Toast.LENGTH_LONG).show();
grid = (GridView)findViewById(R.id.gridView1);
grid.setAdapter(adapter1);
}
if (unique.equals("natural"))
{
Toast.makeText(GridActivity.this, "nat", Toast.LENGTH_LONG).show();
grid = (GridView)findViewById(R.id.gridView1);
grid.setAdapter(adapter2);
}
}
grid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int pos,long id) {
Intent i = new Intent(GridActivity.this, imgPrevActivity.class);
i.putExtra("selectedIntex", pos);
startActivity(i);
Toast.makeText(GridActivity.this,"ddd",Toast.LENGTH_LONG).show();
}
});
}
}
and this is the activity where it supposes to show any clicked on image
public class imgPrevActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.each_image1);
ImageView im = (ImageView)findViewById(R.id.imageView);
int pos = getIntent().getExtras().getInt("selectedIntex");
// ImageAdapter adapter = new ImageAdapter(imgPrevActivity.this, "image prev", null);
long Id= GridActivity.adapter1.getItemId(pos);
im.setImageResource((int) Id);
}
}
i've tried to get the position of image clicked on from the grid
then getting the Id from the position
and setting the image view to that ID
but it doesnt work !!
thats where the images are put in arrays
public class Images {
public static int[] images1 = {
R.drawable.buds, R.drawable.cherry_34,
R.drawable.clouds_2, R.drawable.coffee_beans_2,
R.drawable.death_valley_sand_dunes
};
public static int[] images2= {
R.drawable.morning_glory_pool,
R.drawable.pink_flowers, R.drawable.sun_flower,
R.drawable.sunrise_3, R.drawable.yellow_rose_3,
};
}
You have to pass your image resource id with intent. The list item id of adapter is useless because you have new Activity on the screen.
grid.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int pos,long id) {
Intent i = new Intent(GridActivity.this, imgPrevActivity.class);
i.putExtra("selectedIntex", grid.getAdapter().getItem(pos);
startActivity(i);
Toast.makeText(GridActivity.this,"ddd",Toast.LENGTH_LONG).show();
}
});
and change your code in your ImgPreviewActivity:
public class imgPrevActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.each_image1);
ImageView im = (ImageView)findViewById(R.id.imageView);
int pos = getIntent().getIntExtra("selectedIntex", 0);
im.setImageResource(pos);
}
}
I think it should work
I have one GridView with 3 Column and 3 Rows I want to change Image when User Click any two Images.
for Example I Click First Row 1 and Column 3 Image and Secondly I Click on Row 3 and Column 2 show now i want to change this two Images like Swap the Image How is it Possible ?

}else{

}
iView.setImageResource(mThumbIds[position]);
return iView;
}
private Integer[] mThumbIds = {
R.drawable.a_bhaibij, R.drawable.a_dashera, R.drawable.a_dipawali,
R.drawable.a_gandhi, R.drawable.a_holi, R.drawable.a_indepe,

Swaping the images in the GridView is very simple.What you have to do is
1* Store the cliked position,where you want to perform the swaping .
2* By using those two values perform the swap operation on mThumbIds array.
3* Finally invoke the notifyDataSetChanged() method on the Adapter object i.e im.notifyDataSetChanged();
public class MainActivity extends Activity {
/** Called when the activity is first created. */
int i=0;
int firstClick,secondClick;
GridView gridView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
gridView = (GridView)findViewById(R.id.gridviewmy);
gridView.setAdapter(new ImageAdapter(this));
final ImageAdapter im = new ImageAdapter(this);
gridView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
// TODO Auto-generated method stub
i++;
if( i %2!=0){
firstClick=arg2;
}else{
secondClick=arg2;
Integer help=new Interger(mThumbIds[firstClick]);
mThumbIds[firstClick]=mThumbIds[secondClick];
mThumbIds[secondClick]=help;
notifyDataSetChanged();
System.out.println("Second Click "+i);
}
}
});
}
}
class ImageAdapter extends BaseAdapter{
private Context mContext;
ImageView iView;
public ImageAdapter(Context c){
this.mContext = c;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return mThumbIds.length;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
System.out.println("Item Is :-"+mThumbIds[position].toString());
return position;
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
System.out.println("Geting Id of Item "+mThumbIds[position]);
if(iView != null){
iView.setImageResource(mThumbIds[0]);
Toast.makeText(mContext, "Call", Toast.LENGTH_SHORT).show();
}
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
if( convertView == null){
iView = new ImageView(mContext);
iView.setLayoutParams(new GridView.LayoutParams(85, 85));
iView.setScaleType(ImageView.ScaleType.CENTER_CROP);
iView.setPadding(8,8,8,8);
}else{
iView = (ImageView)convertView;
}
iView.setImageResource(mThumbIds[position]);
return iView;
}
private Integer[] mThumbIds = {
R.drawable.a_bhaibij, R.drawable.a_dashera, R.drawable.a_dipawali,
R.drawable.a_gandhi, R.drawable.a_holi, R.drawable.a_indepe,
R.drawable.a_janmastmi, R.drawable.a_kite, R.drawable.a_newyear
};
}
I think this may solve you problem.
All the best.
Also do the following for updating the grid view images to complete the swap operation:
im.notifyDataSetChanged();
gridView.setAdapter(im);
gridView.invalidateViews()
notifyDataSetChanged(); did not work for me. eclipse gave an error.
so instead of searching for the real solution, if there is one, I just reloaded the java page.
Of course I am saving the state of the images in the gridview (adapter) in internal storage in a file named graphics. So on reload of the java page it repaints with correct images.
It works.
i would like to create a listView, but i want in every listitem to have 2 different textViews and a button..is that possible?
i m using a row xml file for my list items..
public class main extends Activity {
private ListView lv1;
private String lv_arr[]={"a","b","c","d"};
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
lv1=(ListView)findViewById(R.id.list);
lv1.setAdapter(new ArrayAdapter<String>(this,R.layout.row , lv_arr));
lv1.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
switch( position )
{
case 0: Intent newActivity = new Intent(chania.this, cafe.class);
break;
//...........
}
}
});
}
}
Yes, just wrap them in a Layout, for example LinearLayout.
Here is an example - look for Row Layout.
Create your own custom Adapter which extends Base Adapter.
Try the code below(I have used 7 textview,wrapped in a customized layout xml file):
public class Received_invitationAdapter extends BaseAdapter{
Context ctx_invitation;
public Received_invitationAdapter(Context ctx_invitation)
{
super();
this.ctx_invitation = ctx_invitation;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return PartyName.length;
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return PartyName[position];
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = null;
try
{
String inflater = Context.LAYOUT_INFLATER_SERVICE;
LayoutInflater li = (LayoutInflater)ctx_invitation.getSystemService(inflater);
v = li.inflate(R.layout.receivedinvitations, null);
TextView tv_partyname = (TextView)v.findViewById(R.id.tv_receivedinvitation_PartyTitle);
TextView tv_partydate = (TextView)v.findViewById(R.id.tv_receivedinvitation_date);
TextView tv_partytime = (TextView)v.findViewById(R.id.tv_receivedinvitation_time);
TextView tv_partylocation = (TextView)v.findViewById(R.id.tv_receivedinvitation_PartyLocation);
TextView img_chkbox = (TextView)v.findViewById(R.id.img_chkbox_receivedinvitation);
TextView img_inv_accepted = (TextView)v.findViewById(R.id.img_accept_receivedinvitation);
TextView img_inv_rejected = (TextView)v.findViewById(R.id.img_reject_receivedinvitation);
tv_partyname.setText(PartyName[position]);
tv_partydate.setText(PartyDate[position]);
tv_partytime.setText(PartyTime[position]);
tv_partylocation.setText(PartyLocation[position]);
System.out.println(""+img_chkbox.getVisibility());
}
catch(Exception e)
{
e.printStackTrace();
}
return v;
}
The receivedinvitations.xml file contains the 7 textview defined in the getview method.
