Scrolling a textView inside a Gridview

thank you for your time.
I have a list of Strings that a display inside a gridview using an ArrayAdapter. Some of those Strings are long and take too much room. I want to limit the height of each grid cell to 1 line and be able to read the full string when i'm clicking on this cell.
Here's my gridview.xml :
<GridView
android:id="#+id/songSelectionGrid_grid"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/songSelectionGrid_button_back"
android:columnWidth="90sp"
android:horizontalSpacing="10dp"
android:numColumns="3"
android:verticalSpacing="10dp" />
and here is my textview inside my gridview :
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:scrollHorizontally="true"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:maxLines = "1"
android:scrollbars = "horizontal"/>
How can i make the Strings scroll horizontally ?
I've tried a onItemClickListener on the gridview followed by a "setMovementMethod" on the view, but it need to be a TextView and casting it doesn't seem to work
Thanks !

Ok so I've managed to make it work as intended : gridview displaying multiple albums (cover picture + horizontally scrollable text). To do so, I've created my own GridAdapter with the following getView() :
public View getView(int position, View convertView, ViewGroup parent)
{
// TODO Auto-generated method stub
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View gridView = null;
convertView = null;
if(convertView == null)
{
gridView = new View(context);
gridView = inflater.inflate(R.layout.gridtextview, null);
TextView textView = (TextView) gridView.findViewById(R.id.gridView_text);
textView.setText(textArray[position]);
Log.i("GridAdapter","textView.getText :
}
return gridView;
}
The gridView I am populating is composed of the following :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/gridView_topLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/gridView_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:contentDescription="#string/gridTextView_Album"
android:src="#drawable/ic_launcher" />
<HorizontalScrollView
android:id="#+id/gridView_horizontalScroll"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:clipChildren="true"
android:fillViewport="true"
android:scrollbars="none" >
<RelativeLayout
android:id="#+id/gridView_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/gridView_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:isScrollContainer="true"
android:paddingBottom="10sp"
android:singleLine="true" />
</RelativeLayout>
</HorizontalScrollView>
I am not sure this is the best way of doing it but it does work.
But still, keep in mind I'm still a beginner in android dev :)

Gridview multiline Textview cut off

I have a GridView and each cell has an ImageView with TextView under it. Unfortunately if the TextView has more than one line the text gets cut off. I have tried everything but I cant find a solution.
It seems that the row height of the GridView is the problem and not the actual text because you can see half of the text in the Textview.
Here is my code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridView = (GridView) findViewById(R.id.gridView1);
gridView.setAdapter(new ImageAdapter());
gridView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
startActivity(new Intent(Main.this, Acronyms.class));
}
});
}
public class ImageAdapter extends BaseAdapter {
private Integer[] iconImg = {
R.drawable.acronyms, R.drawable.acronyms,
R.drawable.acronyms
};
private String[] iconTitle = {
"Acronyms", "Cardiac Strips",
"Test 3"
};
public int getCount() {
return iconImg.length;
}
public Object getItem(int arg0) {
return null;
}
public long getItemId(int arg0) {
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
View view = null;
if (convertView == null) {
LayoutInflater inflater = getLayoutInflater();
view = inflater.inflate(R.layout.icon, null);
TextView textView = (TextView) view.findViewById(R.id.icon_text);
textView.setText(iconTitle[position]);
ImageView imageView = (ImageView) view.findViewById(R.id.icon_image);
imageView.setImageResource(iconImg[position]);
} else {
view = convertView;
}
return view;
}
}
main.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#a3e6ff"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:paddingBottom="10dp"
android:paddingTop="10dp"
android:shadowDx="0"
android:shadowDy="0"
android:shadowRadius="25"
android:text="Example"
android:textColor="#248fb7"
android:textSize="40dp"
android:typeface="serif" android:gravity="center_horizontal"/>
<GridView
android:id="#+id/gridView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:columnWidth="90dp"
android:horizontalSpacing="10dp"
android:numColumns="3"
android:stretchMode="columnWidth"
android:verticalSpacing="15dp" >
</GridView>
</LinearLayout>
and my icon.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/grid_icon_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical" >
<ImageView
android:id="#+id/icon_image"
android:layout_width="90dp"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/icon_text"
android:layout_width="90dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:maxLines="2"
android:singleLine="false"
android:text="Samples Samples"
android:textColor="#FFFFFF"
android:textSize="15dp"
android:typeface="serif" />
</LinearLayout>
And here is a screenshot:

I resolved using, when i define it
TextView.setLines(2);
in the xml the textview is
android:layout_width="wrap_content"
android:layout_height="wrap_content"

[EDIT1]
You could try using a RelativeLayout instead of a Linear Layout for the icon.xml.
If this doesnt work then I would then move to a static height TextView. From looking at your screenshot, it looks like you will always use the same image, and the text is either going to be 1 line or 2. Just make the text height static to allow for 2 lines.
[ORIGINAL]
I think the problem is in your linear layout definition for your icon.xml. In your definition, you have the layout having "match_parent" as the width and height parameters. You should, since these are to essentially be subviews within the gridview be "wrap_content". Here is what I think it should be
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/grid_icon_layout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical" >
<ImageView android:id="#+id/icon_image"
android:layout_width="90dp"
android:layout_height="wrap_content" />
<TextView android:id="#+id/icon_text"
android:layout_width="90dp"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:maxLines="2"
android:singleLine="false"
android:text="Samples Samples"
android:textColor="#FFFFFF"
android:textSize="15dp"
android:typeface="serif" />
</LinearLayout>

Change ConstraintLayout for LinearLayout.
Make sure you are using ConstraintLayout and if possible change by LinearLayout. For long texts, Constraint is not very good.

Android - GridView height to max height

I've got a GridView inside a scrollview and the GridView has 4 images loaded into it (via an ImageAdapter). My issue is I can get 3 of the images to show but the 4th doesn't. After further investigation, I've found that the height of the gridview is only the height of the row, so if I set the gridview height in xml to 700dp, then it shows up.
Here's a screenshot:
As you can see, I've set the background of the GridView to HotPink to illustrate where the GridView is.
Here's the XML for the main_menu:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/llLayoutContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<!-- <LinearLayout android:id="#+id/llMiddle"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal"> -->
<LinearLayout
android:id="#+id/llLeft"
android:layout_width="400dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/layout_left"
android:paddingLeft="5dp"
android:paddingRight="5dp">
<ScrollView
android:id="#+id/svMenu"
android:layout_width="400dp"
android:layout_height="match_parent"
>
</ScrollView>
</LinearLayout>
<LinearLayout
android:id="#+id/llRight"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical"
android:background="#drawable/layout_right"
android:padding="0dp">
</LinearLayout>
<!-- </LinearLayout> -->
</LinearLayout>
The LinearLayout "llLeft" is the layout where the menu items get loaded (inside the ScrollView). layout_left is only a shape which draws the dark outline around the greenish background.
Here's the main_menu_header.xml which contains the GridView:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingTop="5dp">
<TextView
android:id="#+id/tvDashboardHeader"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Dashboard Main Menu"
android:textSize="20dp"
style="#style/TextShadow"
android:paddingTop="5dp"
android:gravity="left"
android:background="#drawable/menu_item_bg"
/>
<GridView
android:id="#+id/gvMenuItems"
android:layout_width="400dp"
android:layout_height="match_parent"
android:columnWidth="110dp"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:background="#color/HotPink"
android:gravity="center" >
</GridView>
</LinearLayout>
And here's how I populate the GridView:
ScrollView sv = (ScrollView)findViewById(R.id.svMenu);
LayoutInflater liInflater = getLayoutInflater();
ViewGroup vg = (ViewGroup)liInflater.inflate(R.layout.main_menu_header, sv, false);
sv.addView(vg);
//Setup the Main Menu items on the left side.
GridView gvMenuItems = (GridView) findViewById(R.id.gvMenuItems);
gvMenuItems.setAdapter(new ImageAdapter(this));
ImageAdapter class:
ImageAdapter class:
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) {
// if it's not recycled, initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(parent.getLayoutParams().width, 125)); //new GridView.LayoutParams(400, 125));
//imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setMaxHeight(50);
imageView.setMaxWidth(50);
//imageView.setPadding(30, 0, 0, 0);
//imageView.setPadding(40, 30, 20, 30);
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
// references to our images
private Integer[] mThumbIds = {
R.drawable.home,
R.drawable.open_folder,
R.drawable.paper_pen,
R.drawable.person
};
}
I thought the gridview property of android:layout_height="match_parent" would work but it's not. Any ideas as to how I can get the GridView to take up the whole left side, inside the scrollview?

My best guess is that scrollview is giving you problem.
Why do u need scrollview for?
Grid View will handle the scrolling. It is kind of redundant.So please remove it and add inflated view directly to llLeft directly. That shall solve the problem.
In fact, it would be more elegant just to use xml to solve your UI problem. Use <include> tag in your main_menu.xml. Here is how
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/llLayoutContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<!-- <LinearLayout android:id="#+id/llMiddle"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal"> -->
<LinearLayout
android:id="#+id/llLeft"
android:layout_width="400dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/layout_left"
android:paddingLeft="5dp"
android:paddingRight="5dp">
<include
android:layout_width="match_parent"
android:layout_height="match_parent"
layout="#layout/main_menu_header" />
</LinearLayout>
<LinearLayout
android:id="#+id/llRight"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical"
android:background="#drawable/layout_right"
android:padding="0dp">
</LinearLayout>
<!-- </LinearLayout> -->

How to have a ListView with icons beside the text?

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"
>
<ImageView
android:id="#+id/bimage"
android:layout_height="20dip"
android:layout_width="20dip"
android:layout_gravity="left|center"
android:layout_marginTop="10dip"
android:layout_marginLeft="5dip"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
/>
<TextView
android:id="#+id/btitle"
android:layout_toRightOf="#id/bimage"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_marginTop="8dip"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:textSize="18dip"
android:textColor="#ffffff"
android:gravity="center_vertical"
/>
</RelativeLayout>

Android: Listview's row height changes when clicking on the checkbox it contains

I got an activity that contains a single listview.
This listview displays a relativeLayout with a bitmap and a checkbox and when no bitmap is available, a text is displayed.
My problem is with rows that contains no bitmap. When I click on the checkbox, the height of the row changes (increase when checkbox is checked, de crease when unchecked)
activity.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/myListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="#drawable/gradient_divider"
android:dividerHeight="1dp" />
</LinearLayout>
row.xml
<?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:orientation="horizontal" >
<ImageView
android:id="#+id/banner"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:adjustViewBounds="true"
android:layout_toLeftOf="#+id/registrationCheckBox"
android:filter="true" >
</ImageView>
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_centerVertical="true"
android:layout_gravity="left"
android:paddingLeft="5dp"
android:layout_toLeftOf="#+id/registrationCheckBox" >
</TextView>
<CheckBox
android:id="#+id/registrationCheckBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:clickable="false"
android:focusable="false"
android:paddingRight="5dp" >
</CheckBox>
</RelativeLayout>
My activity code
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);
hideActionBar();
// init the controls
initControls();
// populate the listView
this.adapter = new RegistrationAdapter(this, refreshContent());
this.listView.setAdapter(this.adapter);
this.listView.setItemsCanFocus(false);
this.listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
this.listView.setOnItemClickListener(
new ListView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
ViewHolder viewHolder = (ViewHolder) view.getTag();
...
}
}
);
}
Any idea on how to prevent my row height to change when clicking on the checkbox ?

I think you are missing the important part of this code, and that is the Adapter code.
How are you handling switching between bitmap and text?

Perhaps set the ImageView to a fixed height (tall enough to fit in any actual image), or provide a dummy invisible image when there is no real image to show.
