Looks like you are trying to do exactly the way in the image shown. I am just giving an example of how I am trying to achieve this. Here’s how I am doing this. Not very difficult. Just straight implementation of Popup Menu. Step 1 : My Adapter public class ListAdapter extends BaseAdapter{ private ArrayList<String> … Read more
isInEditMode()should be used inside the Custom View constructor. Try the following code: public class GraphView extends View implements Grapher { public GraphView(Context context, AttributeSet attrs) { super(context, attrs); if(!isInEditMode()) init(context); } public GraphView(Context context) { super(context); if(!isInEditMode()){ touchHandler = new TouchHandler(this); init(context); } }
Views inflated from a layout – like your example TextView – are not added to their parent ViewGroup with addView(View child), which is why overriding just that method didn’t work for you. You want to override addView(View child, int index, ViewGroup.LayoutParams params), which all of the other addView() overloads end up calling. In that method, … Read more
Made a few tweaks in your code and it is working fine now. 1] onMeasure function wasn’t proper. Use below logic @Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { if (mCurrentView == null) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); return; } int height = 0; mCurrentView.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); int h = mCurrentView.getMeasuredHeight(); if (h > height) height = … Read more
StaticLayout (similar to DynamicLayout and BoringLayout) is used to layout and draw text on a canvas. It is commonly used for the following tasks: Measuring how big multiline text would be after being laid out. Drawing text on a bitmap image. Making a custom view that handles its own text layout (as opposed to making … Read more

The solution below resolves 2 problems: Custom shape as you presented it The top right side of the button shouldn’t be clickable So this is the solution in 3 steps: Step … Read more
Congratulations! You’ve hit a leaky abstraction. :-/ The problem is this: for better or worse, virtual method calls from constructors invoke the most derived method implementation. C# is the same as Java in this respect; consider the following program: using System; class Base { public Base () { Console.WriteLine (“Base..ctor”); M (); } public virtual … Read more
Long story short, No, but if you do override any constructor, then ensure to call super(…) with the exact same number of arguments (like, see Jin’s answer for example why). If you will add your custom View from xml also like : <com.mypack.MyView … /> you will need the constructor public MyView(Context context, AttributeSet attrs), … Read more
The Snackbar does not allow you to set a custom layout. However, as Primoz990 suggested you can get the Snackbar’s View. The getView function returns the Snackbar.SnackbarLayout, which is a horizontal LinearLayout object whose children are a TextView and a Button. To add your own View to the Snackbar, you just need to hide the … Read more
