adapter not set in the listview android

Hi I am working on the list view, I just want to set the values in the listview. I posted the code as below.As per SimpleAdapter It just shows the name of the content .I want to display the count also.But the count does not displayed and in the app it only shows name of the textview instead of the count. Please suggest me solution for the problem.I also attached the screenshot.

The first textview takes up the full width of the horizontal LinearLayout so you can't see the second textview.
You can see the count by making the width of the textviews wrap_content but it probably won't match the design you're trying to achieve.

Hi i just chage the xml template as follows.

Its working properly now.

onOptionsItemClick or onMenuItemClick not being called

(Very first thing i want to make clear is that i am COMPLETELY NEWBIE, very beginner in android, in fact in programming/coding!)
The menu is referred in onCreateOptionMenu and the calling method is also onOptionsItemSelected to open up menu but the method for each option/item is set as onMenuItemClick and onMenuItemLongClick which is ideal for context menu options/items!
The problem is onMenuItemClick have input parameters as (View v, int position) and I cannot change it to only (View v) or to (MenuItem item).
What I want is clicking on each item of menu should bring out new activity!
I also tried putting all my switch-case-break statements to onOptionsItemSelected method but it is still not working!
I also tried in fragment class, setHasOptionsMenu (true); but it did not work!
onMenuItemClick doesn't get called

...unfortunately, 30000 characters limit has been reached so i cant upload mainActivity.java file!
Kindly help!
Best regards,
sagar

try this code on
Change the following code
onMenuItemClick(MenuItem item)
to
onMenuItemClick(View clickedView, int position)
like this
`#override
public void onMenuItemClick(View clickedView, int position) {
switch (position) {
case 1:
startActivity(new Intent(MainActivity.this, UserProfile.class));
break;
case 2:
startActivity(new Intent(MainActivity.this, UserProfile.class));
break;
}
}`
i hope this help you

If onOptionsItemSelected() method is not called in fragment then just make sure you return false from the onOptionsItemSelected() method of Activity.

Android EditText not editable

I have a 2 activities with edittexts on them the first activity work fine but the second activity's EditText is focused but I can't edit it nor can I click the button on it.
Also everything works in the emulator but not when I install it on the device. (The keyboard popup also does not come up in the second activity where as it does in the first activity)

I just figured to re-create the app. I dont think it is a wise decision to copy the raw files to another directory and use that.

parse JSON into a listView

Would like to get what I am working on in a list view. I pulled some JSON and a bitmap off the net and as of now im have it so I can scroll through them left and right at the click of a button, but would like to place them in a list view instead.
I created the layout for the list view which is this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="65dp"
android:layout_height="65dp"
android:layout_centerVertical="true"
android:layout_margin="5dp"
android:padding="3dp"
android:scaleType="fitXY"
android:src="#drawable/generic" />
<TextView
android:id="#+id/Model"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dip"
android:layout_toLeftOf="#+id/price"
android:layout_toRightOf="#+id/imageView1"
android:maxLines="1"
android:text="title"
android:textColor="#android:color/black"
android:textSize="15dip"
android:textStyle="bold" />
<TextView
android:id="#+id/Price"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginRight="10dp"
android:layout_marginTop="5dip"
android:text="$$$$"
android:textColor="#android:color/holo_red_light"
android:textSize="12dip" />
<TextView
android:id="#+id/Description"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/Model"
android:layout_toRightOf="#+id/imageView1"
android:ellipsize="end"
android:maxLines="3"
android:text="desc"
android:textColor="#android:color/black"
android:textSize="13dip" />
</RelativeLayout>
</LinearLayout>
This is what i want each section of the listView to follow, and I can populate it fine with the JSON information, as well as the Bitmap.

I Just am having trouble populating a list view, any help would be awesome! I tried to folow this one tutorial on list views, but since this class extends Activity, and a listView class extends ListActivity I couldn't seem to get anything to work!

You're going to want to use a custom adapter to display the data. The images will have to be done in the background since they are being loaded off of the net. Here is a very in depth tutorial for listview and adapters
http://www.vogella.com/tutorials/AndroidListView/article.html
For the image loading, or "lazy loading", there are tons of great third part libraries, such has Volley, or my favorite Universal Image Loader

please help me to solve this problem.thanking you in advance.

after getting the title as follows:
title= (TextView) findViewById(R.id.item_title);
use setText method to set the title as you wish.
I think it will solve your problem.
