drawable

问题 Okay, so I am using a drawable PNG (1200 x 1920, 30kb) as a background in an activity. A snippet of my XML code is shown below. My problem is the application is skipping frames and has lagged responses. Could anybody tell me why this is happening, or a good way to solve my problem? I still would like to be able to use this PNG file as the background. Thanks XML Snippet: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools"

问题 I am using Android Studio version 1.2.2 and this how my res folder looks: As you can see there are no drawable folders present. My concern: Is the drawable has been deprecated and instead of it I have to place all the images used in the app in mipmap folders. If I need to create the selectors or any shape for a view I need to place it in the "drawable" or the "mipmap". Does anyone has clue about it? 回答1: Is the drawable has been deprecated and instead of it I have to place all the images used

问题 I am messing around with creating my own dialog class, but I've run into an interesting issue. I use a layer-list drawable for the dialog's close button, but for some reason, the shadow layer disappears after the first time I show the dialog. You can see in the image below: I really have absolutely no idea what could be causing this. I've tried debugging, but I wasn't able to find any leads. Does anyone have any ideas? My code is below. TwoColorDialog.java public class TwoColorDialog extends

问题 I get "bitmap size exceeds VM budget", eventually with my app. So I added all of these things to help alleviate the increasing memory footprint BitmapFactory.Options options = new BitmapFactory.Options(); options.inTempStorage = new byte[32*1024]; options.inDither=false; //Disable Dithering mode options.inPurgeable=true; //Tell to gc that whether it needs free memory, the Bitmap can be cleared options.inInputShareable=true; //Which kind of reference will be used to recover the Bitmap data

问题 I am trying to provide a simple solid-color underline to a TextView header. I want this to be reusable and to work with any view in the future, regardless of height. I am trying to favor a background drawable so I can simply apply it to view. I can draw a line without any problem: <shape xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:shape="line" > <stroke android:color="#8a9299" android:width="1dp" /> </shape> This line is, however,

问题 I've seen this post with a solution to make a Spinner look like an EditText. What I want instead is the spinner to look like an ImageView (the selected Image). This way the Spinner is completely stripped of unnecessary padding and the triangle at the bottom-right. (So on the screen it's an Image, but if you click on it, it opens up like a Spinner.) PS: I already have a custom Spinner with Images as items, but I still have some padding issues and the spinner-triangle that I would like to

问题 I have a problem with the drawable class in R.java file. I had drawable hdpi, mdpi, xhdpi... folders in main/res, but drawable was missing so i created it by hand.
