android-imageview

问题 I have a ListFragment that has a custom adapter so that I could have a text view and an image view on each row. When dragging this row to my canvas (a separate fragment), it shows the whole row as the drag shadow (default behavior). I want to drag only the icon/image to the canvas. My code sample below produces the original drag shadow (whole row from list view) with the desired image drawn behind the cell (a bit stretched because of the bounds setting code). Pretty picture here. According to

问题 What I am trying to achieve is the screenshot below: It has the following: Background layer (in this case, red but ideally could support any image such as a pattern) Rotated picture in the middle Rotated black frame around the picture (ideally could support any 9 patch background) Semi-transparent layer around the black frame (currently black with alpha ~ 50%) In the final product the user will be able to move the picture around to select a certain area from it. The frame and semi-transparent

问题 I have created circle shape drawables that contain png icons. As per the Android Material guidelines the diameter of the circle is 40dp and the icon is 24dp. Initially I did not set any values for left, right, top and bottom as I assumed the internal icon item would stay 24dp. However, it resizes. I then tried using width and height properties to force it to 24dp, which appeared to work in the preview in AS but had no effect on the tablet. Finally I set the values of top, bottom, left and

问题 may I know how to set margin in imageview dynamically? 回答1: You're probably looking for something like this: http://developer.android.com/reference/android/view/View.html#setLayoutParams(android.view.ViewGroup.LayoutParams) Note this part of the method description though: These supply parameters to the parent of this view specifying how it should be arranged Which means that if you have an ImageView inside of a LinearLayout, you need to supply the method with LinearLayout.LayoutParams, like

问题 I have multiple ImageViews on my screen. Whenever the user moves his finger over one or multiple of them, I want the ones the finger touched, to be removed and create new ImageViews. @Override public boolean onTouch(View view, MotionEvent motionEvent) { ((ViewGroup) view.getParent()).removeView(view); createNewImageViews(); return true; } The problem is, that my app crashes. I think the reason is, that a touchlistener is called again, that already deleted its view and tries to delete it again
