Refer to the image above. In AChartEngine, although Zoom Buttons are hidden using method setZoomButtonsVisible(false), it leaves a large space between the X-axis to the bottom.
How do I make the chart stick to the bottom? I have tried many methods without success.
There are multiple way to do this. Please see a few of them below:
Set the height of the legend manually: renderer.setLegendHeight(height);
Make the legend size itself to occupy the needed space: renderer.setFitLegend(true);
Don't show the legend at all: renderer.setShowLegend(false);

I am creating a chart using MPAndroidChart with 10 data sets using one of the examples provided. My labels are displaying all on one single line and are not wrapping. They are getting chopped off on the right.
Legend l = mChart.getLegend();
l.setForm(Legend.LegendForm.SQUARE);
l.setPosition(Legend.LegendPosition.BELOW_CHART_LEFT);
I would like to display the labels in multi-lines. Any ideas please?
Currently this library does not support a "wrapping" mechanism for the Legend.
However a workaround could be to set the legend-position to be somewhere right of the chart.
In that way there should be more space for entries when they are aligned vertically instead of horizontally.
I have a problem with a specific layout in Android.
What I want to achieve is approximately this:

The green area should always be visible at the bottom of the screen (size can change, but only marginally)
The red area should fill the rest of the screen on top.
The cyan area (inside the red layout) is a ScrollView and can change size and should not grow bigger than the space available
What happens is this: when the list expands, depending on the layout (i have tried linear, relative, mix of those,...), either the red or green area is overlapped with the other and is not accessible any more:

I have tried this for a day now and whatever I do, some part of the layout is always overlapped. Is there a way to tell a ScrollView to only expand to a certain height? I know maxHeight doesn't exist. I highly appreciate every input as this is driving me crazy now! Is this possible at all with Android?
I have a few issues and questions regarding some UI development on Android. Firstly look at this image:
Firstly at image A) This is a image that I insert and repeat horizontally to give the zig-zag shape at the top of the screen regardless of screensize and above that a textField with no content and a background color - But as I'm sure you can is that the two colors don't match up quite as perfectly as it should even though they both have the same hex color value (#BF0426). And secondly, you can also see some serious pixelation on that zig-zag image. How do I fix these 2 problems?
And then at image B) Here I have a simple listView. What I would like to do, is firstly indent it a bit on both sides, and round the corners of the top and bottom item. So basically I want it to look like the blue border drawn on the screenshot. (Your typical iOS listView). How do I go about doing this?
Thanks in advance for any tips!
For the image. Just out of curiosity, why wouldnt you simply extend your image to include the top pixels as well? In other words, build your repeating image such that it incorporates the pixels that you are trying to create using the empty textview. This will at least take care of the color missmatch, as the color will all be generated from the same place. In terms of the pixelation. Are you truly repeating the image, or are you spreading the image. A spreading will definitely cause what you are seeing.
For your tableview:
For the left and right indent, you can simply use the margin or padding attributes of tableview item. There are generic padding and/or margin attributes (which will pad all of the top, bottom, left and right), or there are separate padding and/or margin attributes for each top, bottom, left, and right. Here is a great link on padding versus margin that you may want to read.
Difference between a View's Padding and Margin
Example attribute (as called in an XML file) for bottom margin
android:layout_marginBottom
setMargins(left, top, right, bottom) // for setting margins programmatically
Example attribute (as called in an XML file) for top padding
android:paddingTop
setPadding(left, top, right, bottom) // for setting padding programmatically
For the custom top and bottom, you should be able to use the following tutorial
http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/
From here, you should be able to detect the item as the first and last item and set the background property (image) to a background image that has a rounded top or rounded bottom. This is how I do it on the iPhone. I have also implemented things that LOOK like tableviews but are simply vertical layouts with my own custom views that I have made to look like what you are wanting.
One thing to consider is the file format you use is going to mutate the image as you save it (lossy compression), so a .jpg with a certain color may look different than a .bmp with the same color. Make sure you author using the same application and/or export settings when trying to match up images.
Also, if you created your image with a DPI that is not compatible with the android display it can cause serious pixelation in detail areas, especially with gradients and drop shadows.
I need to have two TextViews displaying same number, first of which should display upper half and second lower half in order to animate those parts differently. (See images below, there's an example with '8' digit).

While clipping bottom is perfectly simple (setting TextView's height is just enough), the second task I find very hard. The only solution I came up with till now is to wrap TextView into some layout and set it's y position to negative - it would be OK, but I need to care about optimization because there will be many digits animated in that way simultaneously.
Do any of you know how to achieve this in more effective way?
What about overlaying the top textview OVER the bottom textview (maybe with the white spacer as well?
I'm trying to create some 9patch images that have some text as their content. I define the stretchable area with a black pixel line top and left. And I define the content area with a black pixel line right and bottom.
However, it seems as though Droid is adding padding to the top and bottom of the content area, messing my layouts up. Has anyone else experienced this?
You say you're putting a black pixel line for the top and left? For the top, you should place just a single pixel for the stretch point. For the left, you can place either one or two pixels (two if there are two separate places you would like to stretch). Let me know if I am misunderstanding you though.
