Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);Here’s the documentation of Intent.ACTION_VIEW.
Making a LinearLayout act like an Button
original source : https://stackoverflow.com/questions/5546514/making-a-linearlayout-act-like-an-button
If you want add the Android default background behavior to make a Layout acts like a “clikable” View, set on the targeted Layout:
API 11+ (Pure Android):
android:background="?android:attr/selectableItemBackground"API 7+ (Android + AppCompat Support Library):
android:background="?attr/selectableItemBackground"Any API:
android:background="@android:drawable/list_selector_background"Answers above still true but didn’t help me for just add the default pressed and released UI state (like in a ListView for instance).
https://stackoverflow.com/questions/5546514/making-a-linearlayout-act-like-an-button
I ran into this problem just now. You’ll have to set the LinearLayout to clickable. You can either do this in the XML with
android:clickable="true"Or in code with
yourLinearLayout.setClickable(true);Cheers!
What are the differences between LinearLayout, RelativeLayout, and AbsoluteLayout?
original source : https://stackoverflow.com/questions/4905370/what-are-the-differences-between-linearlayout-relativelayout-and-absolutelayou
LinearLayout means you can align views one by one (vertically/ horizontally).
RelativeLayout means based on relation of views from its parents and other views.
ConstraintLayout is similar to a RelativeLayout in that it uses relations to position and size widgets, but has additional flexibility and is easier to use in the Layout Editor.
WebView to load html, static or dynamic pages.
FrameLayout to load child one above another, like cards inside a frame, we can place one above another or anywhere inside the frame.
deprecated – AbsoluteLayout means you have to give exact position where the view should be.
