Android :: Unable To Add Subview To Linear Layout With Wrap Content

Aug 29, 2010

I'm using data to build elements of a ViewGroup. The ViewGroup are LinearLayouts, except the leaves, which are TextViews. Because Data draws the hierarchy, I inflate the LinearLayouts and TextViews from individual XML files programatically on the fly.

My Problem:
When I create a LinearLayout with the attribute wrap_content, then inflate a TextView or other LinearLayout into it, I can't get the parents (or enough of them, anyway) to redraw, respecting the new view. These LinearLayouts always seem to come out at 0 size, because when they are first created (before their children are inflated), they wrap around nothing. I've tried calling some stock methods of ViewGroup but nothing seems to work.

Android :: Getting Linear Layout To Wrap Contents

Mar 24, 2010

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?

Android :: Can Prevent Words From Breaking In Textview When Using Wrap Content In Android

Sep 20, 2010

I am in the process of trying to convert a desktop app to Android - and am struggling with some very basic stuff. When I specify a layout including a textview that holds a sizable amount of text wrap_content seems to arbitrarily break in the middle of a word - and I can not find any documentation indicating this can be controlled.

Android :: Android - ListView Items Not Grow To Wrap Their Content

Nov 2, 2009

I have a rather complex ListView, with variable list item heights. Under certain conditions, I need to display an additional view in a list item, which is hidden by default (View.GONE). By enabling it (View.VISIBLE), the list item grows in height (or at least it's supposed to).

The problem:
Even though I declare the item's root layout to wrap_content, and each component in the item to fill_parent, the view I hide/show which is supposed to change the item's height is simply cut off at the bottom instead of its parent (the item layout) growing in height to fully display it.

Are there any gotchas related to ListViews and item layouts and item height which I may have missed?

Some more observations:

For testing purposes I have now reduced the list item layout to just contain the root LinearLayout and an ImageView. When I set the LinearLayout height to e.g. 200dip and the ImageView to fill_parent, I would have expected the ImageView to grow until it hits the 200dip limit set by its parent.

However, the image will instead be only ever as tall as its bitmap resource (as if I had set it to wrap_content) and the whole list item will be of the same height (i.e. as if I had set it to wrap_content, too).

If however I set the image height to e.g. 200dip, then the list item will grow in height, and so will the item layout.

In other words, the layout_height of the list item layout is completely ignored, and so is any height value on ImageView other than a hard-coded pixel value.

Android :: Table Row As Linear Layout

Dec 31, 2009

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...

Android :: Add Button To Linear Layout

Jan 5, 2010

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?

Android :: Changing Linear Layout In Widget

Apr 28, 2010

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.

Android :: Writing Custom Linear Layout

Jul 26, 2010

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);

Android :: How To Position Buttons In Linear Layout?

Aug 18, 2010

RelativeLayout is more flexible, and can do what AbsoluteLayout can do and more.
http://developer.android.com/reference/android/widget/RelativeLayout....
To place views on top of one another you can also use FrameLayout, positioning these frame layouts in their parent layout:

> I have an image that will have 5 different areas that will be "clickable." Each clickable area will be invisible and play a different sound. I was told not to use an absolute layout, and use a linear layout instead. However, I am now having an issue with placing the buttons over the picture. The linear layout does not allow me to position them correctly where they need to go. How do I properly position a button so that it is over a certain part of the image?

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.

Android :: Draw Border At Top Of Linear Layout

Dec 17, 2009

I have followed the example in for the gradient dividers: http://www.connorgarvey.com/blog/?p=34. I have tried to draw a horizontal line at the BOTTOM of my linear layout. Here is my linear layout file:

<LinearLayout android:id="@+id/test" android:layout_width="fill_parent"
android:layout_height="wrap_content>
<ImageView android:id="@+id/icon1"
android:layout_width="32dip"
android:layout_height="32dip"
And I did add <View
android:background="@drawable/black_white_gradient"
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_above="@id/test"

But i don't see any line at the top of the LinearLayout. And when I go to Hierarchy View and see he View (for the hort separator), the getWidth() is 0 while getHeight() is 1. Can you please tell me what am I missing?

I am using a linear layout to display a pretty light initial screen. It has 1 button that is supposed to centre in the screen both horizontally and vertically. However no matter what I try to do the button will top align centre. I have included the XML below, can some one point me in the right direction?

android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<ImageButton android:id="@+id/btnFindMe"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
