I am trying to get those nicely looking android list dividers above and below a TextView. This is how far I am. code...
The ImageView makes what I want - a scaled to fill the parent separator, but this is somewhat not an ideal solution. The android:drawable* in the TextView do not scale to fill the parent - any ideas how to achieve this?

I have a simple ExpandalbeList. For the group header view, I'm using a simple TextView, I am setting the background of the text to a drawable. I have the textview parameters set to FILL_PARENT, but the background of the TextView only covers the width of the text. I realize that I can put this all inside of a Linear Layout, but that just seems like a waste. isn't there a way to make the bounds of the text view stretch to the edge of the listview?

Any idea why this doesn't create an activity that looks like a popup instead of an activity that completely fills the screen?

I assumed that I only needed to set the layout height and layout width to something other than "fill_parent", but it still shows up as a black screen that completely fills the screen.
Ultimately, I simply want to create a popup, but I do not want to use an AlertDialog. Is this possible?
I am using a TableLayout in my application. It contains four TableRows each containing four ImageViews. The behavior I want is to scale the layout to fit the shortest dimension. It works fine in portrait mode but fails miserably in landscape mode.
From the documentation it looks like this is because the TableRow layout_height is always set to WRAP_CONTENT. While I can set the dimensions of the individual Views, the TableLayout won't render at all if I set the View layout_height to FILL_PARENT.
I feel like there is something simple I am missing. Is there a way to get the TableLayout with TableRows to scale to fit the height in landscape mode?

I'm battling with extending a TextView for my Android app. I'd like to create "bubbles" to display text messages in a conversation, similar to the native iPhone SMS conversations.
Is there a way to implement the resizing of a background image without just stretching it? I'd like to have a single background image that keeps it's corners but get stretched only in defined areas. I think this should be possible because I've seen it in a SMS app, but I wonder how to implement that.
What is the resolution for different density? Does it really matter or always keep 72 as a resolution?
When placing multiple assets do i need to use fill parent always or i can manually make a measurements for different layout?
I'm trying to create a method for resizing multi-line text in a TextView such that it fits within the bounds (both the X and Y dimensions) of the TextView. At present, I have something, but all it does is resize the text such that just the first letter/character of the text fills the dimensions of the TextView (i.e. only the first letter is viewable, and it's huge). I need it to fit all the lines of the text within the bounds of the TextView.
View 4 Replies View RelatedIs there a way to scale the Drawable passed to TextView.setCompoundDrawables ? The following code works very well but of course is set to the full intrinsic size of the drawable. This code is used with the Holder pattern in a ListView where the purpose is to update the drawable without two more Views (LinearLayout and ImageView) to accomplish the same thing. code...
I suppose I can use Drawable.setBounds() and preserve the original aspect ratio with a small function but just wondering if there this a more direct way to do this with the api?
I have a TextView inside a LinearLayout. The LinearLayout is able to receive focus, and I want the textColor of the TextView to change when it does. I thought using a ColorStateList would work, but it would seem that the TextView does not receive focus when the LinearLayout does. I know that, because I have tried this code...
And nothing gets logged. I don't want to use an OnFocusChangeListener on the LinearLayout to change the textColor of the TextView, I think this has to be done from XML. The reason for that is because in another activity I have an ExpandableListView with a custom adapter and custom views and Android changes the textColors of the TextViews (from light to dark) inside my custom views when items are focused.
It seems that a TextView inside a LinearLayout forces that LinearLayout to be larger. I am trying split my screen top 50% and bottom 50% and also the bottom 50% is split into 3 parts. So I did my weights 3 (for the top), and then 1, 1, 1 (for the bottom) for a total of 6.
Here is what it looks like. http://i.imgur.com/3FJSW.jpg
As soon as I take out the TextView inside the first LinearLayout the splits are proper. The moment I put the TextView inside the top LinearLayout the top LinerLayout gets larger by the amount of the the TextView.
Here is my code:

The layout xml is as below. I have a RelativeLayout, which contains a TextView. The OnClick listener is set on RelativeLayout. The RelativeLayout has a selector background. What I want is, when user clicks on the RelativeLayout, the background of the RelativeLayout should change, and the color of the text of the TextView should change too. Even though I set color selector for the TextView, only the selector on RelativeLayout works. The color selector on TextView doesn't work. How can I implement change of both RelativeLayout background and text color of TextView when user clicks the layout?

I have the Button defined as follows:
CODE:..........
The problem is that 'drawableTop' image is aligned to the top border of the Button view. I would like to center it (together with text label) vertically on the button. 'android:gravity' seems to work only on text label. It does not affect 'drawableTop' positioning.
I was able to center it vertically using 'android:paddingTop' - but that does not seem to be a good idea. I guess it would not work properly on different screen resolution/size.
the cpu scaling of Android.. First, do the system use the lowest frequency when not in use? Aka screem off..After i unlock the phone do it always scale to max frequency or scale it based on the cpu needed? For example write a text makes the phone use thr same freq as playing a game?

View 8 Replies View RelatedI'm battling with Android's retarded layout system. I'm trying to get a table to fill the screen (simple right?) but it's ridiculously hard.
I got it to work somehow in XML like this:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent">
<TableRow android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1">
<Button android:text="A" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
<Button android:text="B" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
</TableRow>
<TableRow android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_weight="1">
<Button android:text="C" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
<Button android:text="D" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_weight="1"/>
</TableRow>
However I can not get it to work in Java. I've tried a million combinations of the LayoutParams, but nothing ever works. This is the best result I have which only fills the width of the screen, not the height:
table = new TableLayout(this);
// Java. You suck.
TableLayout.LayoutParams lp = new TableLayout.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.FILL_PARENT);
table.setLayoutParams(lp); // This line has no effect! WHYYYY?!
table.setStretchAllColumns(true);
for (int r = 0; r < 2; ++r)
{
TableRow row = new TableRow(this);
for (int c = 0; c < 2; ++c)
{
Button btn = new Button(this);
btn.setText("A");
row.addView(btn);
}
table.addView(row);}
Now I'm using the follow code to scale down the image downloaded from internet at runtime. But the result is not good enough.

I'm trying to tell a WebView to scale the page down to a certain percent. I've tried using setInitialScale() as that seems to be exactly what I want, but it seemed to have no effect.
Am I just missing something obvious?

View 2 Replies View RelatedI have an image, say 16px from our designer. I want to Set it as the background image on a view, but the view is larger than the image. So I want to anchor the image at the top of the view, and then have the view fill in the bottom with a solid color.
Is this possible in the current version of android, 1.5_r3?
Here is what I have so far, but the image is scaling to take up the entire view, and I am not sure how to set the image as background and specify a solid color at the same time. I suspect I need to wrap the view in a containing view which has the color specified, is that the best way to do it? code...
