Question 1: Unfortunately the one in which you you say is most intuitive is the least used in Android. As I understand, you should separate your UI (XML) and computational functionality (Java Class Files). It also makes for easier debugging. It is actually a lot easier to read this way and think about Android imo. … Read more
I think problem is here in your code public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { ….. …. //problem is here below line return inflater.inflate(R.layout.input_fgmt, container, false); } return your already inflated view public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View inputFragmentView = inflater.inflate(R.layout.input_fgmt, container, false); ….. …. return inputFragmentView; }
First, there is no best practice defined by Android regarding registering click listeners. It totally depends on your use case. Implementing the View.OnClickListener interface to Activity is the way to go. As Android strongly recommends interface implementation over and over again whether it is an Activity or Fragment. Now as you described : public class … Read more
Imagine that we have 3 buttons for example public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Capture our button from layout Button button = (Button)findViewById(R.id.corky); Button button2 = (Button)findViewById(R.id.corky2); Button button3 = (Button)findViewById(R.id.corky3); // Register the onClick listener with the implementation above button.setOnClickListener(mCorkyListener); button2.setOnClickListener(mCorkyListener); button3.setOnClickListener(mCorkyListener); } // Create … Read more
So I figured out that in order to have some context of which menu icon was clicked, I utilized the setTag() and getTag() methods of the View class and just applied these methods to the ImageView (menu icon).
listView.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Object o = prestListView.getItemAtPosition(position); prestationEco str = (prestationEco)o; //As you are using Default String Adapter Toast.makeText(getBaseContext(),str.getTitle(),Toast.LENGTH_SHORT).show(); } });
It works like this. View.OnClickListenere is defined – public interface OnClickListener { void onClick(View v); } As far as we know you cannot instantiate an object OnClickListener, as it doesn’t have a method implemented. So there are two ways you can go by – you can implement this interface which will override onClick method like … Read more
Interesting question. I tried some solutions and this is what I found that has the same result of what you are trying to achieve. 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
When using a DrawerLayout, there should be only one main content View, with the drawer View – in this case, your ListView – listed after it. Using a DrawerLayout in any other way will result in incorrect, unpredictable behavior, often preventing normal interaction with other layout elements. A tutorial with links to a sample and … Read more
