drawable

问题 Based on some condition, I have to diagonally cut the list cell. For this I have made diagonal drawable image using this code: diagonal_line.xml <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item android:top="0dp" android:bottom="0dp" > <rotate android:fromDegrees="315" android:toDegrees="315" android:pivotX="0%" android:pivotY="0%" > <shape android:shape="line" > <stroke android:width="10dp" android:color="@color/grey" /> <

问题 As far as I know for now (which is little), all the Views in Android have square or rectangular shapes. This is fine almost all the time until you want - what I actually want - to create non-square shapes that could handle events. My goal is to have a circle divided in 3 sections of 120° each. Each section of the circle should behave like a button. The problem is that if we look at those 3rds of a circle and place them in a square box that strictly contains them, they are overlapping each

问题 I'm trying to have a circle background for my TextView, so I created a shape style as below. But I need to have multiple colors with multiple sizes (while the textSize stays constant), so I need to set the width/height in the style. From my understanding..Layer List puts all the shapes on top of one another? Because I need to call it 12 times at different places, so it seems quite cumbersome to have 12 shape style xmls. Is there a better way to have all the different shape/size combinations

问题 I have set up my project with different drawable directories (ldpi, mdpi and hdpi). I have a background png with two different resolutions: 320x480 in drawable-mdpi folder, and 480x800 in drawable-hdpi. Both have the same filename. When I try to load the background as a style in the manifest (using android:windowBackground in the style) if I use the emulator for a 1.6 device, I get the correct one loaded(mdpi). However, if I try this on my Nexus, I see that at first the correct background

问题 I've got a LinearLayout with two EditText descendants (not direct children). I call EditText.setCompoundDrawablesWithIntrinsicBounds(0,0,R.drawable.xyz,0) on each to put a drawable (the same drawable) on the right side of each of the EditText s. The two edit texts are identical, except for their order in the ListView . However, the size of the drawable in the first EditText becomes larger than the second after adding the drawables. Specifically, the first EditText resizes to accomodate the

问题 I have an EditText with a drawable inside. I want to make the drawable clickable so that I can have a specific action when user clicks the drawable. How do I do that? My EditText is: <EditText android:id="@+id/phone" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginBottom="5dp" android:drawableRight="@drawable/question_mark" android:hint="phone number" android:imeActionId="@+id/phone_num" android:maxLines=

问题 I'm currently developing a new app for the company I'm working at. We test this on multiple devices, now a strange thing I noticed the other day, well someone else did. My Colleague tested the app on his HTC one m8, and we have a background image on the login page but it didn't show for him. It did however on a Nexus 7, Samsung Galaxy Tab 4, Motorola G and Samsung S4. This might be very specific, but I guess some people must have noticed this kind of behaviour before on certain devices and

问题 Uisng XML is it possible to create a drawable where half of it would be color1 and another half would be color2? When I set that drawable as a background of a view it should look like in the image below. 回答1: Doing it by xml: <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:right="100dp"> <shape android:shape="rectangle"> <size android:height="100dp" android:width="100dp"/> <solid android:color="@android:color/black"/

问题 I'm android developer from Korea My project has features about loading large amount of huge bitmap (about 2,000 x 1,500px) I had a some experiments to compare time complexity and space complexity between Asset and Drawable By result, Asset is better than drawable in space complexity. When I load huge images using drawable, my app broken down with OutOfMemoryException : the bitmap size exceeds VM budget but when I load huge images using Asset, It works fine! Anybody know reason why this
