Android click listener on View work in strange manner

I have the following layout.xml containing one ScrollView with some elements(picture and text)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

MainActivity.java
public class MainActivity extends Activity{
LayoutInflater inflater;
RelativeLayout MyLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
inflater = LayoutInflater.from(this);
MyLayout = (RelativeLayout) inflater.inflate(R.id.layout, null, false);
MyLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.d("TAG"," I'm clicked! ");
}
});
Click Listener above does not work when I click screen!!!
But if I change code to this - everything is working
MyLayout.findViewById(R.id.clickable).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.d("TAG"," I'm clicked! ");
}
});
So why should I set click listener to LinearLayout inside ScrollView inside parent RelativeLayout?
Why click listener does not work for root xml element RelativeLayout???

The problem is that your ScrollView is intercepting the touch events and not propagating them to parent layouts (in this case your RelativeLayout).
This thread might have some useful information about this topic.

Just add android:clickable="false" in your ScrollView. Then change your MainActivity like below:
public class MainActivity extends Activity {
LinearLayout myLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myLayout = (LinearLayout) findViewById(R.id.layout);
myLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.d("TAG"," I'm clicked! ");
}
});
}
}
Note: activity_main.xml is xml file which you are loading.
Now your OnClick will work as expected.

included bottom layout for all the android activites with onclick events not working

I am new to android development. I want to include the same horizontal Scroll view in all android activities.I have defined the layout and Onclick events in one separate activity and extended that class with other activites.But the onclick events are not working
here is my Base Activity
public class Footer extends AppCompatActivity implements View.OnClickListener {
private ImageView img_school, img_group, img_news, img_schemes, img_jobs, img_gallery, img_goddess, img_services, img_census, img_address, img_abt_us;
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.imgs_school:
Intent i = new Intent(Footer.this, SchoolActivity.class);
startActivity(i);
break;
case R.id.imgs_galary:
Intent gi = new Intent(Footer.this, GalleryActivity.class);
startActivity(gi);
break;
case R.id.imgs_events:
Intent ni = new Intent(Footer.this, EventsActivity.class);
startActivity(ni);
break;
case R.id.imgs_abtus:
break;
case R.id.imgs_jobs:
Intent ji = new Intent(Footer.this, JobsActivity.class);
startActivity(ji);
break;
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_footer);
initAll();
img_gallery.setOnClickListener(this);
img_school.setOnClickListener(this);
img_news.setOnClickListener(this);
img_jobs.setOnClickListener(this);
img_abt_us.setOnClickListener(this);
}
public void initAll() {
img_school = findViewById(R.id.imgs_school);
img_news = findViewById(R.id.imgs_events);
img_jobs = findViewById(R.id.imgs_jobs);
img_gallery = findViewById(R.id.imgs_galary);
img_abt_us = findViewById(R.id.imgs_abtus);
}
}

And i am extending this activity with other classes
such as
public class SchoolActivity extends Footer {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_school);
}
}
And its activity_school xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.evoqis.manovaru.SchoolActivity">
<include layout="#layout/activity_footer"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
But the onclick events are not happening.
Thanks in adavance

Here is the problem:
In subclass you call:
super.onCreate(savedInstanceState);
Which calls:-
setContentView(R.layout.activity_footer); //which creates a new views
initAll(); //which finds views by id
img_gallery.setOnClickListener(this); //setting listeners.
and then in subclass you call:
setContentView(R.layout.activity_school); which creates new view, and overrides all the listeners you have set in superclass.
How to fix it
Move
img_gallery.setOnClickListener(this);
img_school.setOnClickListener(this);
img_news.setOnClickListener(this);
img_jobs.setOnClickListener(this);
img_abt_us.setOnClickListener(this);
Inside public void initAll(), and in subclass do this:
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_school);
initAll();
Also you can remove onCreate() method from superclass.

How to shift a LinearLayout when a SlidingDrawer expands?

I am trying to implement a panel in a fragment that can expand on button click from the right side of the screen. I can't use the navigation drawer, because I already have navigation drawers from both left and right sides.
The idea is to achieve something like that:
I was almost able to do it with the SlidingDrawer widget (it's deprecated..), the only problem is that I don't know how to make the LinearLayout to appear in the middle and then to shift when the button to expand the SlidingDrawer is clicked.
I have the following code:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button handle = (Button) findViewById(R.id.handle);
SlidingDrawer drawer = (SlidingDrawer) findViewById(R.id.slidingDrawer);
drawer.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() {
#Override
public void onDrawerOpened() {
}
});
drawer.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {
#Override
public void onDrawerClosed() {
}
});
}
}
And the XML code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.test.slidingdrawertest.slidingdrawertest.MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST TEST TEST" />
</LinearLayout>
<LinearLayout
android:layout_alignParentEnd="true"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<SlidingDrawer
android:id="#+id/slidingDrawer"
android:layout_width="200dp"
android:layout_height="400dp"
android:layout_marginTop="100dp"
android:layout_gravity="end"
android:content="#+id/content"
android:handle="#+id/handle"
android:orientation="horizontal">
<Button
android:id="#+id/handle"
style="?android:attr/borderlessButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Expand" />
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST TEST TEST" />
</LinearLayout>
</SlidingDrawer>
</LinearLayout>
</RelativeLayout>

You can edit your XML like this
?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp"
tools:context="com.test.slidingdrawertest.slidingdrawertest.MainActivity">
<LinearLayout
android:id="#+id/left" // this is your linear layout
android:layout_width="match_parent" // that you want to shift left
android:layout_height="match_parent"
android:layout_toLeftOf="#+id/right" // apply this property due to
android:layout_alignParentLeft="true" //which if the width of sliding menu
android:gravity="center" //increase it will automatically compressed
android:background="#aa00aa"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST TEST TEST" />
</LinearLayout>
<LinearLayout
android:id="#+id/right"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:background="#0000aa"
android:layout_height="match_parent">
<SlidingDrawer
android:id="#+id/slidingDrawer"
android:layout_width="200dp" // you can check by increasing or decreasing the with of this slidingdrawer
android:layout_height="400dp"
android:layout_marginTop="100dp"
android:layout_gravity="end"
android:content="#+id/content"
android:handle="#+id/handle"
android:orientation="horizontal">
<Button
android:id="#+id/handle"
style="?android:attr/borderlessButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Expand" />
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST TEST TEST" />
</LinearLayout>
</SlidingDrawer>
</LinearLayout>
</RelativeLayout>
apart from this if set any layout to the right of your linear layout which is initially GONE and as you click on the button its visibility changed to INVISIBLE/VISIBLE so it will shift the linear layout to left. Hope that helps!

If you want a little exemple here is my solution: (I don't know if Avani Nagar's solution works or not):
TextView res;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final TextView img = (TextView)findViewById(R.id.second);
res = (TextView)findViewById(R.id.first);
img.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
img.setX(img.getX() - 5);
changew(img.getX());
}
});
}
private void changew(float w){
res.getLayoutParams().width = (int)(res.getX() +w);
res.requestLayout();
res.invalidate();
}
The xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/black">
<TextView
android:layout_toRightOf="#+id/first"
android:text="bonjourrrrrr"
android:id="#+id/second"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:background="#android:color/holo_red_dark" />
<TextView
android:text="salutttttttt"
android:id="#id/first"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:background="#android:color/holo_green_light" />
</RelativeLayout>

I managed to do it, it actually wasn't so difficult, but it's a little tricky. Here is the solution:
The xml code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/topLayout"
tools:context="com.test.slidingdrawertest.slidingdrawertest.MainActivity">
<LinearLayout
android:id="#+id/mainLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST" />
</LinearLayout>
<LinearLayout
android:layout_alignParentEnd="true"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<SlidingDrawer
android:id="#+id/slidingDrawer"
android:layout_width="200dp"
android:layout_height="400dp"
android:layout_marginTop="100dp"
android:layout_gravity="end"
android:content="#+id/content"
android:handle="#+id/handle"
android:orientation="horizontal">
<Button
android:id="#+id/handle"
style="?android:attr/borderlessButtonStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Expand" />
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST TEST TESTT" />
</LinearLayout>
</SlidingDrawer>
</LinearLayout>
</RelativeLayout>
The code in MainActivity.java:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button handle = (Button) findViewById(R.id.handle);
SlidingDrawer drawer = (SlidingDrawer) findViewById(R.id.slidingDrawer);
final View k = findViewById(R.id.mainLayout);
drawer.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() {
#Override
public void onDrawerOpened() {
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_TOP);
k.setLayoutParams(params);
}
});
drawer.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {
#Override
public void onDrawerClosed() {
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
k.setLayoutParams(params);
}
});
}
}
And the explanation: I had to give main main layout an id (in XML) and then find it in the code behind, then I had to apply new parameters to it when the drawer opens or closes. Basically, we need to find the parent layout and set the parameters to it.
Now the LinearLayout is able to shift it's position on drawer open, and it goes back to it's original position on drawer close. Next step is to make this process with an animation, so it's smooth and doesn't just jump back and forth to the new positions.

Can't Get Focus on Button in FragmentActivity

After spending enough time unsuccessfully, I am posting it here to seek help. I have a ListFragment called from the following FragmentActivity. In the Layout there is a Submit button on top, so that user can scroll the list and press the Submit button when done with filling in the information. However I can't click this submit button. It never gets focus. How can I fix it?
Thanks for your help.
I have this FragmentActivity:
public class SurveyFragmentAnchor extends FragmentActivity {
Button submit;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_survey_fragment);
setTitle("Feedback and Survey");
submit = (Button) findViewById(R.id.submit_button);
submit.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Log.v("SURVEY", "Button pressed");
}
});
}
}
And here is the Layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:text="Submit" />
</TableRow>
</TableLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:cacheColorHint="#00000000"
android:drawSelectorOnTop="false" >
</ListView>
</LinearLayout>
<fragment

android:layout_width="match_parent"
android:layout_height="match_parent"

</fragment>

Try using these fields on the button:
android:focusable="true"
android:focusableInTouchMode="true"

Changing views with ViewFlipper Android

I need a little help.I'm using a ViewFlipper to change views in TabActivity but not really sure how to do it.Here is my code :
MainActivity.class
public class Collections extends Activity implements OnClickListener {
ViewFlipper vFlip;
Button genre, recommended, soon;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.collections_layout);
vFlip = (ViewFlipper) findViewById(R.id.tags_flipper);
genre = (Button) findViewById(R.id.genre_btn);
genre.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
vFlip.getCurrentView();
}
});
recommended = (Button) findViewById(R.id.recom_btn);
recommended.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
vFlip.getCurrentView();
}
});
soon = (Button) findViewById(R.id.soon_btn);
soon.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
vFlip.getCurrentView();
}
});
}
}
I have three different xml, which I want to load with clicking the buttons.Here is the collection_layout.xml
