onOptionsItemClick or onMenuItemClick not being called

(Very first thing i want to make clear is that i am COMPLETELY NEWBIE, very beginner in android, in fact in programming/coding!)
The menu is referred in onCreateOptionMenu and the calling method is also onOptionsItemSelected to open up menu but the method for each option/item is set as onMenuItemClick and onMenuItemLongClick which is ideal for context menu options/items!
The problem is onMenuItemClick have input parameters as (View v, int position) and I cannot change it to only (View v) or to (MenuItem item).
What I want is clicking on each item of menu should bring out new activity!
I also tried putting all my switch-case-break statements to onOptionsItemSelected method but it is still not working!
I also tried in fragment class, setHasOptionsMenu (true); but it did not work!
onMenuItemClick doesn't get called
(Deprecated) Fragment onOptionsItemSelected not being called

to
onMenuItemClick(View clickedView, int position)
like this
`#override
public void onMenuItemClick(View clickedView, int position) {
switch (position) {
case 1:
startActivity(new Intent(MainActivity.this, UserProfile.class));
break;
case 2:
startActivity(new Intent(MainActivity.this, UserProfile.class));
break;
}
}`
i hope this help you

If onOptionsItemSelected() method is not called in fragment then just make sure you return false from the onOptionsItemSelected() method of Activity.

do you not just need to repeat the same proccess inside the onCheckChangedListener?
rg.setOnCheckedChangeListener(new OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
//Create another radio group here
//then add it to the view
RadioGroup rg2 = new RadioGroup(this); //create the RadioGroup
rg2.setOrientation(RadioGroup.HORIZONTAL);//or RadioGroup.VERTICAL
rg2.setPadding(dpAsPixels, dpAsPixels, dpAsPixels, dpAsPixels);
final Drawable drawableTop = getResources().getDrawable(R.drawable.document_icon);
for (int i = 0; i < itemTypeArrayList.size(); i++) {
if (itemTypeArrayList.get(i).getActive() == 1) {
rb = new RadioButton(this);
rg2.addView(rb); //the RadioButtons are added to the radioGroup instead of the layout
rb.setText(itemTypeArrayList.get(i).getCode());
rb.setId(itemTypeArrayList.get(i).getId());
}
}
itemDetailsLinearLayout.addView(rg);
}
});
You may need to declare rg2 public at the top of the class so it can be accessed by the onCheckChangedListener

show EditText on condition

Right now I have an idea for a project and I would like to know if anyone can help me on the same logic.
As such I need to create or generate a number of EditText according to amount you enter, ie, to select or enter a number such as 5, show me 5 EditText layout for type 5 values​​. They know that the form could accomplish this? Any ideas please?
I guess it must be a way to do it with a loop, but not like carrying this calculation Java to XML. Thank you.

Here is an example of generating EditText items based on the number you enter. You can ignore the scrollview in the layout file I just put it in case someone added a lot of EditText items that would go off the screen.

Android onclick Buttons Sequence

I have 5 buttons every one has letter (Button "H",Button "E"Button "L"Button "L"Button "O") which make the word "HELLO". what I need is to make on click sequence to these buttons so if I click "H" first and "E" second until complete the word the app will do something, But if I click "L" first will give me some error message.
Any Idea to do this sequence?
Thanks

Just have an Array like this:
int[] tracker = new int[5];
and when you click a button, say "H", set tracker[0] = 1;
but when you click a button, say "L", check whether all the previous button values are 1. If yes, then set the corresponding tracker to 1 else, show an error message, and do not make any change to the tracker Array.
Something Like this:
onHClick{
tracker[0] = 1;
}
onEClick{
for(int i=0; i<1; i++){
if(tracker[i] == 0){
//show error message and return;
}else{
tracker[1] = 1;
return;
}
}
}

You can do something like
When activity started you just make other button Enabled = false of something like that. But make the first button Enabled. Don't make the Visible=false.
Now on click of Button "H" make enable Button "E" and so on.
So user will only have to click the button in sequence. Button can not be presses in any random manner.
Try this and let me know that it works or not.

Very Interesting and exactly same to your requirement..check once..
If you give any string other than HELLO also works better.
public class ButtonTest extends Activity
{
private String result="";
String sampleText = "HELLO";
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
int noOfBtns = sampleText.length();
LinearLayout ll = (LinearLayout)findViewById(R.id.btnlay);
final TextView tvtext = (TextView)findViewById(R.id.result);
final Button[] btns = new Button[noOfBtns];
for(int i=0;i<noOfBtns;i++)
{
btns[i] = new Button(this);
btns[i].setText(sampleText.substring(i,i+1));
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
ll.addView(btns[i], lp);
final int j = i;
btns[i].setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
System.out.println(j+" "+result.length());
if(j == result.length())
{
result = result+btns[j].getText().toString();
if(sampleText.startsWith(result))
{
tvtext.setText(result);
}
}
else
{
Toast.makeText(getApplicationContext(), "Wrong Button Pressed", Toast.LENGTH_SHORT).show();
}
}
});
}
}
}

I don't know exactly your flow but you can try this.
set Tag to each button as its Text, like this.
b.setTag("H");
and than after like this.
Button b;
String name = "";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String s = (String) v.getTag();
name +=s;
if( "HELLO".startsWith(name)){
<VALID>
}else{
<ERROR>
}
}
});
}
check the variable name on each button click with your original word i.e. HELLO like above.

How i can fit to all devices. Can anyone help?? Thanks in advance.

There are couple of possibilities:
use different xml files for different sizes of screen -> check here http://developer.android.com/guide/practices/screens_support.html
you may use scrollview -> http://developer.android.com/reference/android/widget/ScrollView.html
or simply make your layout fit to the smallest screen size you like to support and then just have "a little" unused space on the larger screens.
It really depends on what you need. Probably the most compatible and advanced solution would be 1.
BUT be aware of the fact that EVERY change on the screen layout has to be duplicated for each xml file following this route!

create xml for each device separately. follow this
second way:
create a parent LinearLayout and pass it to the following method
public static boolean isTabletPC(Context context) {
Display display = ((WindowManager) context
.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
if (display.getWidth() >= 1200) {
isTabletPC = true;
return isTabletPC;
} else {
isTabletPC = false;
return isTabletPC;
}
}
public static void fixUiDeviceDependencies(
Activity act, LinearLayout llParent) {
if (Utilities.isTabletPC(act)) {
Display display = ((WindowManager) act
.getSystemService(Context.WINDOW_SERVICE))
.getDefaultDisplay();
LayoutParams params = (LayoutParams) llParent
.getLayoutParams();
params.width = display.getWidth() / 2;
llParent.setLayoutParams(params);
}
}
