I tested fragments, but dealing with fragment makes things much more complex and the fragment itself needs saving and restoring which may not work in a webview which has javascript state, So I searched more and find a nice article somewhere and with some modification I came to a solution which I suggest: First, add … Read more

There is no built-in scale type that allows the ImageView to automatically upscale the image and keep its aspect ratio intact. The only scale type that does upscaling is fitXY, which won’t respect the aspect ratio, as you found out yourself too. That being said, this topic has already been visited more than once. Have … Read more
I got this same error message when I tried to use TextView.setText passing a char instead of a String. This makes sense since the char would be promoted to an int which meant that I was really calling the TextView.setText( int resId ); And since there wasn’t a resource with that value, it wouldn’t work.
There is no such event. You can simply post a message/Runnable in the UI events queue at the beginning of a drawing sequence to have this message/Runnable executed after drawing is complete (see View.post(Runnable) for instance.) Also, getLeft/getTop return the correct value after measurement and layout, you don’t need to wait for drawing to end … Read more

I was able to get to the contents of an Activity with this call: ViewGroup view = (ViewGroup)getWindow().getDecorView(); You should probably check that getDecorView returns an instanceof ViewGroup for all cases, but with a LinearLayout in the Activity the code above runs fine. To get to the LinearLayout you could then just: LinearLayout content = … Read more
