ListView doesn't show first textview item

ListView doesn't show first textview item - android

I am trying to make a listview, every row contains an imageview and two text views. The image and the second textview is shown but the first textview is blank...Can't figure out what's wrong...I can't wrap my head around custom list adapters...I have read http://commonsware.com/Android/excerpt.pdf to.
My data is loaded correctly to the arraylist.
My code:
private class SongAdapter extends ArrayAdapter<Szam> {
private ArrayList<Szam> items;
public SongAdapter(Context context, int textViewResourceId, ArrayList<Szam> items) {
super(context, textViewResourceId, items);
this.items = items;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.row, null);
}
Szam o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.firstLine);
TextView bt = (TextView) v.findViewById(R.id.secondLine);
if (tt != null) {
tt.setText(o.getArtist()); }
if(bt != null){
bt.setText(o.getTitle());
}
}
return v;
}
And my xml layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:minHeight="?android:attr/listPreferredItemHeight"
android:layout_height="wrap_content" android:padding="6dip">
<TextView android:id="#+id/secondLine" android:layout_width="fill_parent"
android:layout_height="26dip" android:layout_toRightOf="#+id/icon"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true" android:singleLine="true"
android:ellipsize="marquee"
android:text="Simple application that shows how to use RelativeLayout" />
<TextView android:id="#+id/firstLine" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_toRightOf="#+id/icon"
android:layout_alignParentRight="true" android:layout_alignParentTop="true"
android:layout_above="#id/secondLine"
android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical"
android:text="My Application" />
<ImageView android:layout_marginRight="6dip" android:id="#+id/icon"
android:src="#drawable/play" android:layout_width="wrap_content"
android:layout_height="fill_parent" android:layout_alignParentLeft="true"></ImageView>
</RelativeLayout>
The corrected layout is:
<TextView android:id="#+id/secondLine1" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_toRightOf="#+id/icon"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true" android:singleLine="true"
android:ellipsize="marquee"
android:textColor="#ffffff"
android:textSize="12sp"
android:text="Simple application that shows how to use RelativeLayout" />
<TextView android:id="#+id/firstLine1" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_toRightOf="#+id/icon"
android:layout_alignParentRight="true" android:layout_alignParentTop="true"
android:ellipsize="marquee"
android:textColor="#ffffff"
android:textSize="16sp"
android:layout_alignWithParentIfMissing="true"
android:text="My Application" />
<ImageView android:layout_marginRight="6dip" android:id="#+id/icon"
android:src="#drawable/play" android:layout_width="wrap_content"
android:layout_height="fill_parent" android:layout_alignParentLeft="true"></ImageView>

Can't you use LinearLayouts?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent"
android:minHeight="?android:attr/listPreferredItemHeight" android:layout_height="wrap_content" android:padding="6dip">
<ImageView android:layout_marginRight="6dip" android:id="#+id/icon" android:src="#drawable/play" android:layout_width="wrap_content"
android:layout_height="fill_parent"></ImageView>
<LinearLayout android:id="#+id/linearLayout1" android:layout_width="wrap_content" android:orientation="vertical"
android:layout_height="wrap_content">
<TextView android:text="My Application" android:layout_height="wrap_content" android:gravity="center_vertical" android:id="#+id/firstLine"
android:layout_width="fill_parent"></TextView>
<TextView android:singleLine="true" android:text="Simple application that shows how to use RelativeLayout" android:layout_height="wrap_content"
android:ellipsize="marquee" android:id="#+id/secondLine" android:layout_width="fill_parent"></TextView>
</LinearLayout>
</LinearLayout>

Remove one layout from listview dynamically

I am working on an application in which I am using custom listview and for my listview I have define a row layout for customisation.
In my row layout I have two Relative layouts.
I want to dynamically remove that one Relative layout from my listview and then add it again.

You could do that in the adapter class's getView method.
For a particular row by inflating the view and getting the relative layout by using findViewById().
e.g.,
RelativeLayout relativeLayout1 = (RelativeLayout) view.findViewById(R.id.relativeLayoutId);
You can hide the layout by using
relativeLayout1.setVisibility(View.GONE);
and unhide using
relativeLayout1.setVisibility(View.VISIBLE);

Listview displays only one row from the list

I am new to android listviews and I am trying to populate a listview in android by a list of items coming from a webservice. I know that the list contains more than one record coming from the webservice but my custom listview displays only the first record from the list. I checked the size of the list and there is always more than one records but the listview is showing only one of them. My custom adapter is like following:
public class ListAdapter extends BaseAdapter {
Context ctx;
LayoutInflater lInflater;
ArrayList<LItem> lstItems;
ListAdapter(Context context, ArrayList<LItem> objects) {
ctx = context;
lstItems = objects;
lInflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return lstItems.size();
}
#Override
public Object getItem(int position) {
return lstItems.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
if (view == null) {
view = lInflater.inflate(R.layout.list_style_task
, parent, false);
}
LItem p = getProduct(position);
((TextView) view.findViewById(R.id.tvMaterial )).setText(p.getMName() );
((TextView) view.findViewById(R.id.tvTask )).setText(p.getTName() );
((TextView) view.findViewById(R.id.tvBQuantity )).setText(p.getBQ() );
// CheckBox cbBuy = (CheckBox) view.findViewById(R.id.checkbox);
//cbBuy.setOnCheckedChangeListener(myCheckChangList);
// cbBuy.setTag(position);
// cbBuy.setChecked(p.selected);
return view;
}
LItem getProduct(int position)
{
return ((LItem) getItem(position));
}
ArrayList<LItem> getBox() {
ArrayList<LItem> box = new ArrayList<LItem>();
for (LItem p : lstItems) {
// if (p.selected)
// box.add(p);
}
return box;
}
OnCheckedChangeListener myCheckChangList = new OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
//getProduct((Integer) buttonView.getTag())= isChecked;
}
};
}
I am binding the listview as:
protected void onPostExecute(List<LItem> li ) {
super.onPostExecute(lstItm);
if(lstItm.size()>0) {
Adp=new ListAdapter(myactivity,lstItm);
lvTasks.setAdapter(Adp);
Log.d("Size---------",Integer.toString(lstItm.size()) );//here it writes more than one as size of the list.
}
}
My xml file for displaying lists is like this:

Issue was with the scrollview which was createing the issue. I just removed

and it worked for me :)

How to make the listView row height change based on content?

I have the following layout which corresponds to a row in a list view. I wanted the TextView in the middle to expand based on the length of text.
With the below layout, my textview is not even visible. Can someone point out what mistake I am doing?
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="3dip"
android:paddingLeft="6dip"
android:paddingRight="6dip" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_centerVertical="true"
android:clickable="true"
android:scaleType="fitXY"
android:src="#drawable/batman" />
<LinearLayout
android:id="#+id/user_info"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/imageView1"
android:orientation="horizontal"
android:paddingBottom="5dp"
android:paddingLeft="10dp"
android:paddingTop="5dp" >
<TextView
android:id="#+id/username"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#color/display_name_color"
android:textSize="14dp" />
<TextView
android:id="#+id/handle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="15dp"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textSize="12dp" />
</LinearLayout>
<LinearLayout
android:id="#+id/actions"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_toRightOf="#+id/imageView1"
android:orientation="horizontal"
android:paddingBottom="5dp"
android:paddingTop="5dp" >
<ImageView
android:id="#+id/favourite"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="center_vertical"
android:layout_marginLeft="40dp"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/bookmark"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="center_vertical"
android:layout_marginLeft="60dp"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<TextView
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/actions"
android:layout_below="#+id/user_info"
android:layout_toRightOf="#+id/imageView1"
android:paddingBottom="5dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="5dp"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
and this is my adapter's getView function.
#Override
public View getView(int position, View convertView, ViewGroup container) {
ImageView imageView;
if (convertView == null) {
LayoutInflater layoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.list_row, container, false);
imageView = (ImageView)convertView.findViewById(R.id.imageView1);
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
} else {
imageView = (ImageView)convertView.findViewById(R.id.imageView1);
}
imageView.setTag(position);
imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
int position = Integer.parseInt(v.getTag().toString());
mOnProfilePicClickCallback.onItemClick(position);
}
});
//Load TextFields here
Feed feed = (Feed) getItem(position);
User user = null;
if (feed != null) {
user = (User) CommonData.users.get(feed.owner);
TextView handle = (TextView) convertView.findViewById(R.id.handle);
TextView userName = (TextView) convertView.findViewById(R.id.username);
TextView feedContent = (TextView) convertView.findViewById(R.id.feedcontent);
handle.setText(feed.owner);
if(tweeter!=null && !TextUtils.isEmpty(user.displayname))
{
userName.setText(user.displayname);
}
else
{
userName.setText(feed.owner);
}
feedContent.setText(feed.feedcontent);
}
// Finally load the image asynchronously into the ImageView, this also takes care of
// setting a placeholder image while the background thread runs
if(user!=null)
{
mImageFetcher.loadImage(user.profileimageurl, imageView);
}
return convertView;
}

Try this...
Remove android:layout_above="#+id/actions"from your "content" TextView
Add android:layout_below="#+id/content" to your "actions" LinearLayout
Remove android:layout_alignParentBottom="true"from "actions"
It may work, if it still doesn't use LinearLayouts instead of RelativeLayout.

In my ListView, every row height changes automaticly according the data.

Android RelativeLayout not center

I have a problem about TextView in RelativeLayout is not center, (only some objects)
First, I'm use ListAdapter for ListView.
public class ListAdapter extends ArrayAdapter<Menu> {
private LayoutInflater inflater;
public ListAdapter(Context c, ArrayList<Menu> o) {
super(c, 0, o);
inflater = (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(int position, View v, ViewGroup parent) {
View view = null;
if (v == null) {
view = inflater.inflate(R.layout.row, null);
} else {
view = v;
}
final Menu data = this.getItem(position);
TextView title = (TextView) view.findViewById(R.id.title);
ImageView background = (ImageView) view.findViewById(R.id.background);
ImageView icon = (ImageView) view.findViewById(R.id.icon);
TextView subtitle = (TextView) view.findViewById(R.id.subtitle);
subtitle.setText(data.getSubTitle());
title.setText(data.getTitle());
background.setImageDrawable(data.getBackground());
icon.setImageDrawable(data.getIcon());
return view;
}
}
and, My row.xml.

This xml's Graphic Design
But in Device(example grouper) , i discover this problem.
In some object, (example see Help ~) Was centered properly. but, other objects, wasn't centered properly.
and i discover this problem another device(different resolution, size, Android version, density).
What can i do solve this problem??

Try this..
Add android:layout_centerHorizontal="true" for subtitle TextView
<TextView
android:id="#+id/subtitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/title"
android:layout_marginTop="5dip"
android:gravity="center_vertical"
android:layout_centerHorizontal="true"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />

or this
<TextView
android:id="#+id/subtitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_below="#+id/title"
android:layout_marginTop="5dip"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall" />

View inflater=getLayoutInflater().inflate(R.layout.list2, list, false);
TextView textdestination=(TextView)inflater.findViewById(R.id.textdestination);
textdestination.setHeight(50);
textdestination.setWidth((textlayoutwidth*25)/100);
textdestination.setTextSize(100);

You can do that in the getView() method of the Adapter you use for the ListView.
mInflater = (LayoutInflater) mActivity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.list, parent,
false);
holder.tv1 = (TextView) convertView
.findViewById(R.id.textdestination);
holder.tv2 = (TextView) convertView
.findViewById(R.id.textflight);
holder.tv3 = (TextView) convertView
.findViewById(R.id.textairline);
.......
.......
.......
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
if(someCondition){
holder.tv1.setLayoutParams(new LinearLayout.LayoutParams(50,50));
holder.tv2setLayoutParams(new LinearLayout.LayoutParams(50,50));
holder.tv3.setLayoutParams(new LinearLayout.LayoutParams(50,50));
.....
.....
.....
}
return convertView;
}

you can change your textview width and height on runtime with :
textdestination.setWidth(pixels);
textdestination.setHeight(pixels);
