I have a problem with my Android Application. In my Application I have a ListView and each item in it contains some text and an image. I want each of the items to open up a different layout. These layouts will just contain some simple text. But I can't seem to find out how to get my items (in the ListView) to open different layouts. Please help!

Here is my New Activity
import android.app.Activity;
import android.os.Bundle;
public class NewActivity extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.poetry);
getIntent().getExtras().getInt("id");
}
}
you need to listen to the click on the item, so something like following before you return the convertview
convertView.setOnClickListenere(new OnClickListener(){
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, NewActivity.class);
startActivity(intent);
}
});

I have a customer adapter where my layouts such as buttons edittext,textview,spinner are there.I'm getting all the value of the items in my Activity where there is an action for button of saving.Now I.m having problem on how to get the value inside my spinner because it gets a null value.here's my code

Try this-
Edit your CustomAdapter class by adding a private Context variable. Then, in the constructor of the CustomAdapter, initialize that variable.
Then you will have a Context to reference every time you need to make a Picasso call.
So, Custom Adapter should look like this:
private class CustomAdapter extends ArrayAdapter<RowData> {
private Context mContext;
public CustomAdapter(Context context, int resource,
int textViewResourceId, List<RowData> objects) {
super(context, resource, textViewResourceId, objects);
mContext = context;
}...
Then make Picasso calls in getView() like this"
Picasso.with(mContext)... and add whatever else you need.
Hope this helps!
I cant seem to find out how to get my ListView (OnListItemClick), to open different activity´s. I know i somehow need to get some row-id for my ListView, but i dont know how to. Right now every row in my ListView just opens up the same activity.
Sorry for my bad English, hope You understand.

And my NewActivity looks like this:
import android.app.Activity;
import android.os.Bundle;
public class NewActivity extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.poetry);
getIntent().getExtras().getInt("id");
}}
You don't need to get the "row ID of the ListView", you need to get the "row ID of the item that was clicked in the Listview"
Luckily, Android gives you the row ID right there as the last parameter of onListItemClick(), where you're currently using the position:
public void onListItemClick(ListView parent, View v, int position, long id) {
Intent intent = new Intent(this, NewActivity.class);
// intent.putExtra("position", position); // not what you want
intent.putExtra("id", id); // more likely what you want
startActivity(intent);
}
If you do not have an ID, you can also get the actual item, i.e. a RowData object in your case, from the ListAdapter:
public void onListItemClick(ListView parent, View v, int position, long id) {
RowData item = (RowData) getListAdapter().getItem(position);
Intent intent = new Intent(this, NewActivity.class);
intent.putExtra("id", item.mId);
startActivity(intent);
}
In both cases, you have to change your code in NewActity so you extract the ID, not position, from the extra bundle.
Another update:
Lets say my list have 10 items, item 1, item 2, item 3 and so on. When item 1 is clicked i want that to open a new activity, let's call that NewActivityOne, and NewActivityOne will refer to a layout with some text called layoutone. Item 2 will also open a new activity, NewActivityTwo, which will refer to a new layout called layouttwo. And that's how I want it to be for all my items.
If your detail activities differ only in the layout (i.e. not in any behavior/code), just use putExtra() to pass an R.layout.* ID (let's call it "layoutId") to your NewActivity and use that in setContentView(getIntent().getExtras().getInt("layoutId"));.
If your detail activities differ more widely, create a separate Activity class for every list item, and in onListItemClick() create an Intent with the respestive activity class you want to display.
In either case, you can store the details to display (int layoutId or Class<Activity>) in your RowData class so you can easily access it in onListItemClick().
I have a list in which each object is of type Task. I have created a list that sows all the task details in the row of the list.
My code is given below:
lv=this.getListView();
if(createtaskSubList().size() != 0)
{
//createTaskSubList gives me the List of taskObjects
MyCustomAdapter adapter = new MyCustomAdapter(this,createtaskSubList());
lv.setAdapter(adapter);
lv.setDividerHeight(2);
lv.invalidateViews();
}
}
private ArrayList<Task> createtaskSubList() {
// TODO Auto-generated method stub
ArrayList<Task> taskSubList= new ArrayList<Task>();
String[] values={ Integer.toString(userId),Integer.toString(number),Integer.toString(page)};
String taskList = Helper.getfromUrl(taskDataFetch,values);
if(taskList.length()!=0)
{
String delims = ("[|]");
String[] tasks = taskList.split(delims);
int i=0;
//Splitting Task series into individual items
for (i = 0; i < tasks.length; i++) {
String limit = ("','");
String[] taskItem = tasks[i].split(limit);
taskSubList.add(new Task(taskItem[1],Integer.parseInt(taskItem[2]),Integer.parseInt(removeCharAt(taskItem[0],0)),Integer.parseInt(taskItem[4]),Integer.parseInt(taskItem[5]),taskItem[6],Integer.parseInt(taskItem[3])));
}
}
return taskSubList;
}
Now my arrayadpter class is:
import java.util.ArrayList;
import android.app.Activity;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
public class MyCustomAdapter extends ArrayAdapter<Task> {
private final Activity context;
ArrayList<Task> taskSubList =new ArrayList<Task>();
public MyCustomAdapter(Activity context,ArrayList<Task> taskSubList) {
super(context, R.layout.teammember, taskSubList);
this.context = context;
this.taskSubList=taskSubList;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View rowView = inflater.inflate(R.layout.teammember, null, true);
final TextView text = (TextView) rowView.findViewById(R.id.label);
final TextView status = (TextView) rowView.findViewById(R.id.status);
final TextView time = (TextView) rowView.findViewById(R.id.time);
//time.setText(formatTime(taskSubList.get(position).getTimeSpent()));
text.setText(taskSubList.get(position).getName());
if(taskSubList.get(position).isCompleted()==0)
{
status.setText("Not Completed");
status.setTextColor(Color.RED);
}
else
{
status.setText("Completed");
status.setTextColor(Color.parseColor("#468765"));
}
return rowView;
}
I need to change it such a way that list should contain only names and when I click on these names an intent has to be called which gives a layout showing the details of that particular TaskObject.Details here means the properties of that task object which should be shown in the form of text views in new layout.Not a dialog or Toast..
In your getView()
status.setOnClickListener(new MyClickListener(position));
public class MyClickListener implements OnClickListener {
private int posi;
public MyClickListener(int position) {
this.posi = position;
}
public void onClick(View v) {
CustomDialog customDialog = new CustomDialog(ViewDetials.this);
customDialog.show();
// Toast.makeText(getBaseContext(), "text view clicked",Toast.LENGTH_SHORT).show();
}
}
}
