Android :: How To Make Linear Layout Scrollable?
Nov 22, 2010
is it possible to make an entire linear layout scrollable when it needs to be? (when all of the elements in the layout don't fit on the main screen)?I know it is doable with views, etc.but is there a way to incorporate everything on the layout to be scrollable at the same time?Maybe scrollable is not the right term. basically - if one of the elements (a button in this case) doesn't entirely make it onto the main screen of the phone and I need to slide a finger down to access it if that makes sense.

I have 3 text views in a layout, where the text clips a tad on the bottom on my droid 2...how can I ensure that the whole text is viewable and the user can scroll down (simply with their finger) to see the rest of my text?

I am programatically adding custom views to a vertical LinearLayout, and I would like there to be some space between the views. I have tried adding: setPadding(0, 1, 0, 1) to my CustomView constructor, but this doesn't seem to have any effect. It was pointed out that I should use margins. Since I am dynamically adding views, I need to set the margins from code (not in xml). I believe the way to do this is below, but it isn't working.
public class MyView extends View {
public MyView (Context context) { super(context);
MarginLayoutParams params = new MarginLayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); params.setMargins(0, 10, 0, 10); setLayoutParams(params);
I also tried using MarginLayoutParams as a parameter while adding the views to the Linear layout (as below). This also did not work:
MarginLayoutParams params = new MarginLayoutParams(linearLayout.getLayoutParams());
linearLayout.setMargins(0, 10, 0, 10); linearLayout.addView(view, params);

I have defined the layout which you can see at the end of this message. I do not understand, why the button is not displayed. If I move the button to the top that the rendering works.

I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now.The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application.Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through.I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful.EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)

I have a registration form in a LinearLayout as shown below:When emulator screen is in it's default position it is working fine. But when I rotate the emulator screen it only displays the elements which are fit to screen and remaining are wrap up. As shown in below screen:Now I want to make this layout scrollable but not getting the idea.

I am trying to create a basic datasheet in my application using a TableLayout. The first row contains the titles of each column. Every row thereafter is data. I would like the data to be scrollable while keeping the first title row visible (i.e. the first row would not scroll with the rest).I have tried something like the following (unsuccessfully)

One of my activities receives some data.I want to obtain a layout like the one for the "contacts" app, which has 1 contact on each row and clicking a row you pass to another activity which shows the details.
What do I need to create the "list" layout?
Are those rows simply TextViews or what else?
How do I generate the rows at runtime into the layout?
If it is too long to write down some code, just tell me what I need and I'll check by myself.

Any insights/pointers regarding creating a layout like this. I have wasted quite a bit of time on this. I want to create a vertical linearlayout which has multiple ExpandableListViews separated by TextViews.
CODE:.........................
I tried the following approaches but each of them has one shortcoming or the other:
1. Add TextView and ExpandableListViews to a linearlayout. The problem with this approach is that LinearLayout by default is unscrollable.
Adding the LinearLayout to a ScrollableView creates even more issues because ListViews handle their own scrolling behavior.
2. I tried using a single ExpandableListView to model the above layout but the problem is that setGroupIndicator applies to the entire ExpandableListView, not a specific group.

I've noticed a strange thing with a TableRow.
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0">
<TableRow
android:background="#9932cc"
android:minHeight="40px"
android:orientation="horizontal">...........
This code doesn't work properly as TextView text1 doesn't wrap it just stretches beyond the screen. I've managed to get it working by embedding this LinearLayout into RelativeLayout but it seems to be the least elegant solution plus I don't understand what's wrong with the code above...

I have a linear layout like this:
<LinearLayout android:id="@+id/header" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:gravity="center_vertical" <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="top" android:src="@drawable/img1" /> <TextView android:id="@+id/atitle" android:singleLine="true" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout>
I need to add a button to the above layout problematically which is right justified? I need to do that in code instead of layout xml file (this is because i can't modify that layout xml file). Here is what I am doing: LinearLayout header = (LinearLayout) findViewById(R.id.header); Button buyButton = new Button(this); buyButton.setText(R.string.buy_ringtone); buyButton.setLayoutParams(new LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); header.addView(buyButton);
But the button does not appear. Can you please tell me how can i achieve that?

As far as I have read in the Internet and official documentation, it isn't possible to make a scrollable app widget. Also all my tries failed. I even tried to subclass TextView to implement my own scroll method, but nothing worked.Are there any ways to achieve that? there are solutions if you use for example htc sense or home desktop ++, but i want to make it available to other users which don't use this

Is there a way to do a linear layout with multiple lines? I want to lay out a variable set of buttons with variable labels, so I'd like to use a layout that works as a simple horizontal LinearLayout, but with multiple lines, so the buttons spill into a second (or third) line if they don't fit on the first one.

I've got a horizontal Linear Layout that contains a variable number of child Linear Layouts. Right now, the children will just run off the screen if there are too many of them. How would I make the parent layout wrap the children on multiple lines? If this is not possible, should I be using a different layout as the parent?

I have this really annoying problem:In my widget, i would like to change the background by code. I noticed on the Google doc than I can easily change the background of an Imageview: remoteViews.setImageViewResource (R.id.my_iv, R.drawable.my_bg);Ok, too easy, i want to change now the Linear layout.. What I read about the remoteview id that I can change a Bitmap, Int, Bool, String, etc. but not a drawable. So i guess i cannot use:remoteViews. set Bitmap (R.id.my_ll, "setBackgroundDrawable",BitmapFactory.decodeResource(context.get Resources(), R.drawablemy_bg));I am totally disapointed and tried a last idea: views.setInt (R.id. my_ ll,"setBackground Resource" ,R.drawable.my_bg);But The logcat told me: android. widget. Remote Views $Action Exception: view: android. widget.LinearLayout can't use method with RemoteViews:setBackgroundResource(int)I am totally lost and I really don't know what to do.

I have a custom layout that draws a transparent rounded rectangle beneath its children. The problem is when I try to add it to my xml file, it doesn't show up. Also, when I try to add parameters to it (i.e. android:layout_width) the popup shows that none of them are available. The same thing happens to any child views I add. public class RoundRectLayout extends LinearLayout
{ private RectF shape;public RoundRectLayout(Context context)
{super(context);
LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layoutInflater.inflate(R.layout.settings, this);
shape = new RectF();
}public RoundRectLayout(Context context, AttributeSet attrs)
{ super(context, attrs);
LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layoutInflater.inflate(R.layout.settings, this);
shape = new RectF();
} @Override
protected void onSizeChanged(int w, int h, int oldw, int oldh)
{shape = new RectF(0, 0, w - 5, h - 5);
super.onSizeChanged(w, h, oldw, oldh);
}@Override
protected void dispatchDraw(Canvas canvas)
Paint temp = new Paint();
temp.setAlpha(125);
canvas.drawRoundRect(shape, 10f, 10f, temp);
super.dispatchDraw(canvas);
