Android :: Strange Looking Rounded Rectangles?
Nov 2, 2010
I'm using the following to draw rounded-corner rectangles in my Android application and it seems to be working alright but with one minor problem:
CODE:.......
(Adding labels to the rectF's defined above follows) ...
The strange thing is that the two ends of the rectangle aren't rounded over the same. The left-size quarter circles are noticeably smaller than the ones on the right.
Anybody experienced anything similar? It's weird enough that I might change my mind about the round corners if I can't do anything about it.... And if I knew how to do a screen capture from my Android, I would.
The rectangles in question are 78 pixels wide and 48 tall, if that helps (and since ykatchou may be onto something).

I am trying to find the number of rectangles per sec in three different size rectangles. I did find it though. But the only problem is that I see all the rectangles after it ran the program completely. But I would like to have rectangles drawn, when I call canvas.drawRect(rec1,paint); function.
I am also looking to keep the old rectangles on the screen while new ones are drawn. I tried with lots of different options nothing worked. To display the rectangles. Can anybody show me the direction to which way to go?
package com.Benchmark.Rectangle; import java.util.TimerTask; import android.R.anim; import android.app.Activity; import android.app.AlertDialog; import android.graphics.drawable.shapes.*; import android.os.Bundle; import android.content.Context; import android.graphics.*; import android.view.View; import android.view.animation.Animation; import android.widget.Button; import android.widget.TextView; import android.widget.Toast; Code...

My Android application has a MapView. I want to divide that MapView into a grid according to latitude and longitude, and shade the different cells of that grid different colors based upon a certain criteria. What's the simplest way to do this?
I could create semi-transparent, solid-color PNG Drawable rectangular images and put them in an ItemizedOverlay centered on the central points of the cells, but then the rectangles would grow and shrink as the user zoomed in and out on the map. I could extend MapView and override the zoom functions so that the rectangles got re-sized when the user zoomed, but that seems really complicated for something that should be simple! Please tell me a better way to do it?

In android, ImageView is a rectangle by default. Is it possible to make it a rounded rectangle (clipped off all 4 corners of my Bitmap to be rounded rectangles) in the ImageView? If yes, can you please tell me now can I do that?

The following code snippet draws a red rectangle:
RectF rectangle = new RectF(50, 100, 100, 50);
Paint paint = new Paint();
paint.setColor(Color.RED);
canvas.drawRoundRect(rectangle, 0, 0, paint);
However if i change rx and ry both to a positive value, say 5, than nothing is shown. Any ideas?

I have a specific drawable that I use as background in my app. It is not a solid color.
Now I want to add rounded corners to this drawable.
I only found the rounded corner available in a shape with a gradient or a solid color as a background but not another drawable.
Is there another easy way of adding rounded corners to a drawable?

I've been asked to make an app that has a list with items looking similar to this snapshot from Hero: http://www.flickr.com/photos/jaxxdotorg/3640222441/in/set-72157619952...Is there a way to reuse this in any way or do I have to re-design it from scratch?

I'm not very experienced in Java. Is there an easy possibility to get a border and round edges around a LinearLayout? (perhaps with XML parameters)
Or do I have to draw my own widgets.

I can create a shape that is a rectangle with all edges rounded. However, what I'm wanting is a rectangle shape with only 2 of the edges rounded. Is this possible?
I'm essentially hacking together a ListView that looks like a bubble with rounded edges. I'm looking to add a header that has the two top edges rounded and a footer with the two bottom edges rounded.

I have a small project in which I download images from Internet in the form of drawable and use them in Imageview for which I have provided functionality similar to an Imagebutton but without the gray edges. The question is that is there any functionality in Android (similar to IPhone) by which we can crop the drawable from edges to make them rounded edged drawable. Even if its a "not-tested-neither-recommended" method, do let me know. I would like to work on this a bit.

I have this Listview element:
<ListView
android:id="@+id/category_list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="@drawable/list_background"
android:layout_marginTop="10sp"
android:layout_marginLeft="10sp"
android:layout_marginRight="10sp"
android:drawSelectorOnTop="false"
android:listSelector="@drawable/list_item_background"
android:cacheColorHint="#FFFFFF"
android:clipToPadding="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:clickable="true"a
ndroid:longClickable="true"
android:footerDividersEnabled="true"
android:headerDividersEnabled="true"
android:dividerHeight="1px" />
where list_background is:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<corners android:radius="10dp" /> <solid android:color="#FFFFFF"/>
</shape>
The list view loads itself with the rounded corners, but then, the items of the list hide the round corners.

On the android website, there is a section about color drawables. Defining these drawables in xml looks like this:
<resources>
<drawable name="solid_red">#f00</drawable>
<drawable name="solid_blue">#0000ff</drawable>
<drawable name="solid_green">#f0f0</drawable>
</resources>
In the java api, they have thr following method to define rounded corners:
setCornerRadius(float radius)
Is there a way to set the rounded corners in the xml?

I want to have 3 edittext with top and bottom having topleft and topright curves but bottom-left and bottom-right straight. I tried to use shape
but it makes all the corners curved. If i try to use bottomRightRadius, then i get exception.
So I tried different way of doing it
using -ve margin so that bottom on hides the upper one's curve. But now bottom one is going behind the upper one. There is nothing like goToBottom or goToTop .

I have already posted on their developer group but based on everything I've seen I don't expect a reply. I have a strange problem. When I added and adview to my app it imported a bunch of comments that all start with /** Eclipse is acting like it is not a comment. Although it isn't erroring out it has now marked anything starting with R.id as not existing. Is this something I can remedy in eclipse or is it time to chuck my dreams of being mega rich off of all the admob revenue I will be receiving? Writing code is one of few things that teaches me I don't know everything. Join the Closed Beta of Call Girl Manager http://www.fuligin.com/forums

With the XML layout shown below, I have some views wrapped in a GestureOverlayView. As shown below, my first row is blended with the second row, as-if the first row is transposed right on top of the second. Now when I take the GestureOverlayView out of the code and leave everything else as-is, my table looks fine - the rows are separate and not on top of each other..........

I have a simple app that just initiates a wifi scan every two seconds and then logs the results. I am observing some strange behaviour, and was wondering if anyone could shed some light. When I start scanning, if the phone (Nexus One running latest Froyo OTA release) is just sitting on my desk (screen on or off, it doesn't matter), I receive the wifi scan results about 800ms after initiating the scan, fairly consistently. At most, it takes a second and a half to receive the results. However, if I get up and start to walk around the building that I'm in, the time between initiating the scan and receiving the result begins to vary greatly. What is interesting is that I start to see a pattern where it will take about 40 seconds to receive results, then I will get three or four results two seconds apart, then it takes 40 seconds to receive the next set of results, then I get three or four results two seconds apart, etc.
I've tried obtaining a wifilock, both the FULL and SCAN ones, and that doesn't help. Same with a partial wakelock. I've also tried setting up a thread that pings the supplicant every second and reports when it is unreachable, and it appears to always be responsive (ie., I never see the report). I thought that maybe the problem was that I am unable to receive the result of scans when I am switching between base stations (which might happen when I move around), but if I manually switch between two different networks, it does not cause a delay in my scans (ie., I can still get the results with only a one second delay while it's associating with the new network). Anyway, for my application, it would be incredibly useful to get wifi results at a fairly consistent rate, and so I was hoping that someone on this list might have some suggestions as to how I can achieve this.

A customer just notified me that she's experiencing the infamous "app not responding / wait, force close" message during a specific operation. By just waiting enough, the app resumes ok. Now, that specific operation is indeed long and in fact it has been programmed in a background thread, with a progress dialog signaling the wait. I can't reproduce the problem on my development phone - I suppose because it's perhaps faster than the phone of the user. But I can't reproduce the problem either with the emulator, which I suppose is slow enough. Generally speaking, I think I could be able to solve this specific problem with the customer giving me the proper feedback. It's the general issue that hassles me. This part of the application is very good covered by tests at different levels, including automated black-box tests with Robotium that drive the UI as the user would do, and even in "stress mode" (repeating the test multiple times). So I supposed to be very safe in that area and I'm disappointed to discover that it was a false sense of safety. What am I possibly missing? Also, is it possible / does make sense to "slow down" a phone during tests? I was thinking of a service running in background just consuming some CPU cycles to make the phone less responsive.
