问题 I have a RelativeLayout called "Dress" with LayoutParams of WRAP_CONTENT. All that is inside it is an ImageView, so it is the same size as the ImageView. When I add one more view to the RelativeLayout in OnCreate, like this: photoSorter = new MultitouchImagesView(this.getApplicationContext()); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); ((ViewGroup) findViewById(id.Dress)).addView(photoSorter, params); The

问题 ConstraintLayout is powerful but tricky sometimes. I want to implement a layout with the ConstraintLayout which can be easily achieved with the LinearLayout . The Blue area is parent constraintLayout. The red part is LinearLayout.

It will be changed at runtime. The red box should remain to maintain wrap

问题 While creating a Layout, I cam across FitWindowsLinearLayout but can't seem to understand the difference between LinearLayout and FitWindowsLinearLayout .

That means that you should not use it. Secondly, to answer your question: as you can see from the implementation, it has one public method, which sets a listener:

问题 I am trying to animate a horizontal list item dismiss the alpha animation works and the layoutparam values also decrease over time but for some reason that doesn't change the actual height of the list item. @Override protected void applyTransformation(float interpolatedTime, Transformation t) { final int initialHeight = view.getMeasuredHeight(); if(interpolatedTime == 1){ imageAdapter.remove(view, position); }else{ view.getLayoutParams().height = initialHeight - (int)(initialHeight *

问题 I have a ViewGroup and I'm adding child Views to it like this: mViewGroup.addView(view, new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); (the WRAP_CONTENT is important for the onclicklistener to work as expected). So far so good, but later I move the child Views around dynamically by either overriding their onDraw methods or by overriding the ViewGroups: protected boolean getChildStaticTransformation(View child, Transformation t) The problem is that the Children

问题 I'm not very expert in android's Fragment. In my last project i was using TabActivity, but because of it's deprecation now I'm starting implements an ActionBar using Fragments.

问题 I have a RecyclerView that utilizes a Recycler Adapter to output a list layout, like this: http://i.imgur.com/ORkXXTb.png I need to attach the model below to each of the list items, such that if the user clicks on any element in the list item (like the circle or one of the two TextViews), it passes the model object to the next Activity . Here is the User model: public class User { private String id; private String username; private String displayName; private Object deletedAt; private
