imageview

问题 Hi I know how to fetch an string from jsonobject, but my question is how to fetch an image from Rest api and display it.

问题 I currently have an imageview element that upon being touched, that tests if the action is an actiondown event, and if it is, it gets the coordinates of the touch with getraw(x or y) and then carries out an action based on those coordinates. How would I implement this to get two sets of coordinates from a two finger multitouch event? 回答1: Take a look at the ACTION_POINTER_DOWN action define in MotionEvent . This is the event that will get called when additional fingers come down after the

问题 I am trying to implement a textview over an image in a framelayout at the center and bottom of the layout as it is seen here: http://developer.android.com/resources/articles/layout-tricks-merge.html <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:layout_width="fill_parent" android:layout_height="fill_parent" android:scaleType="center" android:src="@drawable/golden_gate" />

问题 So in API Level 11 Google introduced the ability to rotate an ImageView (Yay, after they introduced the possibility to Animate such a rotation, yay smart thinking, yay!) But how should I go about to rotate an ImageView using e.g. API level 8? I can't use setRotation() as described above. 回答1: RotationAnimation was present since Api level 1 RotateAnimation animation = new RotateAnimation(from, to, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); animation.setInterpolator

问题 I have an ImageView with a share intent( which works great, brings up all the apps I can share the image with), however, I can not share the photo because it has no path on my phone. How do I go about saving the ImageView on my phone? Below is my code. public void taptoshare(View v) { View content = findViewById(R.id.myimage); content.setDrawingCacheEnabled(true); Bitmap bitmap = content.getDrawingCache(); File file = new File("/DCIM/Camera/image.jpg"); try { file.createNewFile();

问题 i am using 9 image view's i want set images to imageview randomly , when I click on refresh button, but I tried like this it's working for random allocation of images but it's repeating the same image in two (or) three imageview's at a time. where is the problem in my code.. final int[] imageViews = { R.id.imgview11, R.id.imgview12, R.id.imgview13, R.id.imgview21, R.id.imgview22, R.id.imgview23, R.id.imgview31, R.id.imgview32, R.id.imgview33 }; final int[] images = { R.drawable.i1, R.drawable

问题 I want to draw a border around an image. But I can't align the border at the ImageView itself (like it is done mostly) because I translate and scale the image inside of the ImageView with the ImageMatrix (the ImageView itself is fill_parent / fills the whole screen). I had the idea to add a second image (which looks like a border) and translate & scale it in the same way as the image which should have a border, but it isn't very handy to do it this way. Has anybody a better idea to reach that
