I wish to add an ImageView inside a ListView. I would like the image to fill the layout without distorsion (basically, fill the height and adapt its width).
This is what I get now:
I have put a grey background to the ImageView to make it easier to see. In red, it's the size I wish to get.
Here is my code:
Project_form.xml
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/name_project"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:padding="3dp"
android:layout_alignParentLeft="true"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textSize="25dp" >
</TextView>
<Button
android:id="#+id/button_project"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/btn_custom"
android:layout_centerVertical="true"
android:focusable="false"
android:focusableInTouchMode="false"
android:layout_alignParentRight="true"
android:padding="3dp"
android:text=" details "
android:textSize="20dp"
android:visibility="invisible" />
<ImageView
android:id="#+id/imagesstep"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#color/grey"
android:adjustViewBounds="false"
android:layout_centerVertical="true"
android:padding="3dp"
android:layout_alignParentRight="true"
android:visibility="invisible" />
</RelativeLayout>
method getView() of my Adapter :
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
if (row==null) {
LayoutInflater inflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row = inflater.inflate(R.layout.project_form, parent, false);
}
TextView text = (TextView) row.findViewById(R.id.name_project);
text.setText(this.objects[position].getName());
int IDImage=this.objects[position].getIDImage();
int IDPlay = this.objects[position].getIDPlay();
text.setCompoundDrawablesWithIntrinsicBounds(IDImage, 0, 0, 0);
text.setCompoundDrawablePadding(7);
ImageView image = (ImageView)
row.findViewById(R.id.imagesstep);
image.setVisibility(View.VISIBLE);
image.setImageResource(IDPlay);
if (position == selectedPosition) {
row.setBackgroundColor(Color.parseColor("#8000ff00"));
}
else {
row.setBackgroundColor(Color.TRANSPARENT);
}
return row;
}
I tried to play with different parameters such as ScaleType, android:adjustViewBounds and layout_width but the height of my image never changed. I also tried to do it programatically (something like image.setMinHeight(parent.getHeight()) but it failed too.
Could anyone point me out what is going wrong?
Many thanks
Try changing the RelativeLayout of the layout_height to fill_parent
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent">
<TextView ... />
<Button .. />
<ImageView ... />
</RelativeLayout>
Alternatively you could set the minHeight attribute of the ImageView to ?android:attr/listPreferredItemHeight
<ImageView
...
android:minHeight="?android:attr/listPreferredItemHeight" />
Remove the padding from your imageview

I just need a way to show default picture on all imageview ( see below ) used in a listview.
This layout is used by an adapter, so no setContentView function is called on this layout. I think this is causing the problem ( the default images doesn't appear ). How can I fix it ?
The image defaultpic.png is in the drawable folder and is 100x100px.
My code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="0dp"
android:paddingRight="0dp"
tools:context=".MainActivity"
android:background="#222222"
android:paddingTop="2dp"
android:paddingBottom="2dp">
<TextView
android:id="#+id/profile_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Title"
android:textColor="#fcdb8c"
android:background="#222222"
android:textStyle="normal"
android:textSize="15sp"
android:layout_alignParentTop="true"
android:lines="1"
android:scrollHorizontally="true"
android:ellipsize="end"
android:paddingRight="40dp"
android:paddingLeft="2dp" />
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:id="#+id/profile"
android:scaleType = "fitXY"
android:src="#drawable/defaultpic"
android:background="#151515"
android:padding="1dp" />
</RelativeLayout>
#Override
public View getView(View convertView, ViewGroup parent) {
RelativeLayout profileLay = (RelativeLayout)profileInf.inflate
(R.layout.profile_layout, parent, false);
TextView profileView = (TextView)profileLay.findViewById(R.id.profile_name);
ImageView coverView = (ImageView)profileLay.findViewById(R.id.profile);
profileView.setText(currProfile.getName());
Drawable img = Drawable.createFromPath(currProfile.getCover());
coverView.setImageDrawable(img);
return profileLay;
}
As k3b said:
your generated layout for the listviewitem has the image
therefore you do not see the default picture.
the way to correct this is to add an if statement.
ImageView coverView = (ImageView)profileLay.findViewById(R.id.profile);
if (Drawable.createFromPath(currProfile.getCover()) == null) {
Drawable img = Drawable.createFromPath(currProfile.getCover());
coverView.setImageDrawable(img);
}
This will cause it to only load the profile cover if it isn't null, but if it is then the default profile image will be used.
your generated layout for the listviewitem has the image
<RelativeLayout...>
<ImageView android:id="#+id/profile" android:src="#drawable/defaultpic" ... />
</RelativeLayout>
and when the listviewitem is created you immediately overwrite the picture in the imageview
#Override
public View getView(View convertView, ViewGroup parent) {
...
ImageView coverView = (ImageView)profileLay.findViewById(R.id.profile);
Drawable img = Drawable.createFromPath(currProfile.getCover());
coverView.setImageDrawable(img);
...
therefor you do not see the default picture
I have a ListView and I wanted to place a small rectangle on the side of each item. To do so I made the following rendered layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="3dp">
<View
android:layout_width="5dp"
android:layout_height="fill_parent"
android:id="#+id/item_color_image"
android:background="#color/wallet_holo_blue_light"
android:layout_marginRight="3dp"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginTop="3dp"
android:layout_marginBottom="3dp" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/item_icon_image"
android:src="#drawable/m"
android:layout_toRightOf="#+id/item_color_image"
android:layout_centerVertical="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Business Name"
android:id="#+id/item_title_text"
android:layout_toRightOf="#+id/item_icon_image"
android:layout_marginLeft="3dp"
android:textStyle="bold"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_alignTop="#+id/item_icon_image" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Distance"
android:id="#+id/item_distance_text"
android:layout_alignLeft="#+id/item_title_text"
android:layout_alignBottom="#+id/item_icon_image"
android:layout_marginBottom="-10dp" />
</RelativeLayout>
When I inflate this layout in a frame, it works just fine.....BUT when I inflate it inside a ListView I get this:
The rectangle's height is being ignored to match the container's height.
I inflate it using this code:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View itemView = convertView;
if (itemView == null) {
itemView = inflater.inflate(R.layout.business_item_view, parent, false);
}
Business currentBusiness = businesses.get(position);
ImageView icon = (ImageView) itemView.findViewById(R.id.item_icon_image);
icon.setImageBitmap(currentBusiness.getIcon());
TextView name = (TextView) itemView.findViewById(R.id.item_title_text);
name.setText(currentBusiness.getName());
TextView distance = (TextView) itemView.findViewById(R.id.item_distance_text);
distance.setText("2 Km"); // TODO: Calculate distance
return itemView;
}
How can I fix this? Thanks!!
Having your root item for a ListView row be match_parent for height doesn't make sense; each item would fill the ListView. I expect that's automatically being changed to wrap_content somewhere.
And RelativeLayouts don't support children with match_parent for height if the RelativeLayout's height is wrap_content. It works with LinearLayouts, so you should look into switching to that. Source: combining wrap_content on parent and fill_parent on child
I'm trying to have a ListView with icon and text but there is a little problem as you can see in the screen shot (only a very small part of text is visible!):
Here is the xml files creating this layout:
//The overall layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android" >
<ListView
android:id="#+id/ListView01"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
</LinearLayout>
// this layout is for single rows
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/lIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/lText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
Edit: This is the getView method of my custom adapter.
public View getView(int position, View convertView, ViewGroup parent) {
View myView = convertView;
cu.moveToPosition(position);
if (convertView == null) {
LayoutInflater li = getLayoutInflater();
myView = li.inflate(R.layout.listicon, null);
ImageView imageView = (ImageView) myView.findViewById(R.id.lIcon);
myView.setLayoutParams(new GridView.LayoutParams(60, 90));
myView.setPadding(8, 8, 8, 8);
byte[] b = Base64.decode(cu.getString(2),Base64.DEFAULT);
imageView.setImageBitmap(BitmapFactory.decodeByteArray(b, 0, b.length));
TextView textView = (TextView) myView.findViewById(R.id.lText);
textView.setText(cu.getString(1));
}
//cu.moveToNext();
int catID = cu.getInt(0);
myView.setTag((Object) catID);
return myView;
}
Try setting layout_width of the ListView and TextView to fill_parent
EDIT: you're resetting list item width in the getView. Either remove or correct your code
Use a relative layout for your rows and place the text right of the image as below :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/lIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/lText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/lIcon"/>
</RelativeLayout>
This is related to the way single row is inflated in the adapter
You should try using
LayoutInflater#inflate(layoutId, parent, false)
as suggested in this answer:
https://stackoverflow.com/a/1662611
Try this layout for the row layout:
Adjust the IDs to yours.. also notice the android:layout_toRightOf id.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"

android:layout_height="20dip"
android:layout_width="20dip"

The grid view of my application has 3 rows and 3 columns. I want this to fill the screen ,irrespective of the screen size of the device.
I tried getting window size and setting the layoutparams accordingly. But this is not giving a perfect alignment as it works with weightsum in linearlayout.
So can we use weightsum for gridview or is there any other android property that can be used.
Thanks a lot for time and response.

}
return convertView;
}
static class ViewHolder {
TextView text1;
ImageView image;
}
pls see the line
convertView.setLayoutParams(new GridView.LayoutParams(h-45, h-39));
i arrived at this value with some trials on different size emulator.
But i dont think its a right way to define height and width.
As far as i understood your question, as you have not posted any code, what you are trying to do is, you want gridview to appear on full screen.
Firstly you must be using some layout to put your gridview in. Do the following:
Make height and width of the layout to fill parent:
android:layout_width="fill_parent"
android:layout_height="fill_parent"
then, set height and width of your gridview to fill_parent as well.
Well, this is just a supposed solution that you might have been working this way. putting some code would be much better. Hope this works for you.
Update:
Well the problem may lie here:
convertView.setLayoutParams(new GridView.LayoutParams(h-45, h-39));
change to:
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT);
convertView.setLayoutParams(new GridView.LayoutParams(params));
Hope this works for you.
#preetha: first of all look at this example i used this and my layout did not affect irrespective of devise height and width....
http://developer.android.com/resources/tutorials/views/hello-gridview.html
set the following in xml
android:id="#+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:columnWidth="90dp"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"
hope this helps...
Here I only changed width and height as match parent and wrap content.

And in the Mainclass add this -->
GridLayoutManager gridLayoutManager=new GridLayoutManager(this,2);
recyclerView.setLayoutManager(gridLayoutManager);
To adjusting Gridview to screen size
In onCreate take rowHeight :
root = binding.root
view.onGlobalLayout {
rowHeight =
root.measuredHeight / currentPageNumberOfRow
fillView(appsList)
}
In adapter:
override fun getView(position: Int, ConvertView: View?, parent: ViewGroup?): View? {
var mConvertView = ConvertView
if (layoutInflater == null) {
layoutInflater =
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as
layoutInflater!!.inflate(R.layout.item_app_shortcut, null)
}
if (mConvertView == null) {
mConvertView =
layoutInflater!!.inflate(R.layout.item_child_launcher_app, null)
//Add this:
mConvertView.layoutParams = AbsListView.LayoutParams(GridView.AUTO_FIT, rowHeight)
}
Dont forget set row image:
android:layout_width="0dp"
android:layout_height="0dp"
To fit on screen
I am trying to create a list item layout with 4 items. It is very similar to the example here with some key differences:
the RelativeLayout layout_height may be larger than listPreferredItemHeight
the image is a CheckBox
there are three TextViews
The top and middle TextViews could have visibility set to GONE
What I would like is: If _label is gone, then _message and _definition should be evenly weighted in the layout. If _label and _message are gone, _definition should be centered. I have tried several variations of height, width, gravity, layout_gravity and I even tried to solve this with a LinearLayout (both as the whole layout and just to contain the vertical text). The only way I can get this to work is if I set layout_height to listPreferredItemHeight, but then only two of the text views fit.

Adapter getView Code using the xml from blessenm's answer
#Override
public View getView(int position, View convertView, ViewGroup parent){
Log.d(Global.TAG,"Position "+position);
View newView;
if (convertView != null )
newView = convertView;
else {
LayoutInflater layout = LayoutInflater.from(MyActivity.this);
newView = layout.inflate(R.layout.alarm_list_item, null);
}
String tmp1 = "Place Holder Label"
TextView label = (TextView)newView.findViewById(R.id.alarm_list_item_label);
LayoutParams l = label.getLayoutParams();
if (tmp1.matches("^\\s*$")){
label.setLayoutParams(new LinearLayout.LayoutParams(l.width,l.height,0f));
} else {
label.setLayoutParams(new LinearLayout.LayoutParams(l.width,l.height,1f));
}
label.setText(tmp1)
String tmp2 = "Place Holder Message"
TextView message = (TextView)newView.findViewById(R.id.alarm_list_item_message);
l = message.getLayoutParams();
if (tmp2.matches("^\\s*$")){
message.setLayoutParams(new LinearLayout.LayoutParams(l.width,l.height,0f));
} else {
message.setLayoutParams(new LinearLayout.LayoutParams(l.width,l.height,1f));
}
message.setText(tmp2);
TextView location = (TextView)newView.findViewById(R.id.alarm_list_item_location);
location.setText("location");
return newView;
}
Layout_gravity will only work inside a linear layout. When you want all your textviews to take even height, put them in a linearlayout with vertical orientation and give weight as 1 for all the textviews. So now all of them will take equal heights.
When you need to hide the textviews, just set their layout_weight to 0, now the remaining textview will take the full available space. And if you give the textview gravity="center", the text will be centered both vertically and horizontally.
