I'm trying to inflate a list of views in a LinarLayout directly in the onCreate() method from the activity. However, I'm having a problem somewhere in the code but I really can't see it, I'm turning around this problem for two days, I'm going crazy !
The problem is that when I run the activity, the linear layout is completely empty, there is only the title.
Here is the important part of the code, KeyItems activity :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.keyitems_layout);
initializer();
ll = (LinearLayout) findViewById(R.id.ll);
LayoutInflater inflater = LayoutInflater.from(this);
for (int i = 0; i < list.size(); i++) {
View view = inflater.inflate(R.layout.keyitem_temp, ll, false);
final TextView ind = (TextView) view.findViewById(R.id.ind);
final TextView item = (TextView) view.findViewById(R.id.item);
ind.setText(list.get(i).get("id"));
item.setText(list.get(i).get("item"));
ll.addView(view);
}
}
Here is the keyitems_layout :
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#color/black" >
<LinearLayout android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#color/black">
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp" />
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="#string/key_items"
android:textSize="36sp"
android:textColor="#color/white" />
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="4dp" />
<LinearLayout android:id="#+id/ll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="32dp"
android:layout_marginRight="32dp"
android:orientation="vertical"
android:background="#color/white" >
</LinearLayout>
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#color/white"
android:text="caca"
android:padding="32dp" />
</LinearLayout>
</ScrollView>
And finally, my keyitem_temp.xml which I'm inflating :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/black"
android:padding="4dp"
android:orientation="horizontal" >
<TextView android:id="#+id/ind"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"
android:textSize="18sp"
android:textColor="#color/blue" />
<TextView android:id="#+id/item"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"
android:textSize="18sp"
android:textColor="#color/white"/>
</LinearLayout>
I have an other activity called ItemsActivity which is the same code with some little differences and it works. Any suggestion? Thanks in advance.
Try using wrap_content for all of your heights except the initial ScrollView:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#color/black" >
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#color/black">
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dp" />
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="#string/key_items"
android:textSize="36sp"
android:textColor="#color/white" />
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="4dp" />
<LinearLayout android:id="#+id/ll"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="32dp"
android:layout_marginRight="32dp"
android:orientation="vertical"
android:background="#color/white" >
</LinearLayout>
<TextView android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#color/white"
android:text="caca"
android:padding="32dp" />
</LinearLayout>
</ScrollView>
and:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/black"
android:padding="4dp"
android:orientation="horizontal" >
<TextView android:id="#+id/ind"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:textSize="18sp"
android:textColor="#color/blue" />
<TextView android:id="#+id/item"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_gravity="center"

I have a nestedscrollview with content like some RelativeLayout, CardViews and textviews. I am using a floatingactionbutton library for some reasons, as well. So I can't use any behavior for it. I don't know how I should handle the scrollchangelistener from scrollview to hide and show the fab dynamically like a behavior.
Now, When programs or output cover full page of intent, the fab is totally disappeared. It may be behind the content. I cant access fab. I want the FloatingActionButton over the scrollview. Or show and hide the fab is also need. Please tell how to achieve that concept?
Any suggestions how to hide and show the fab while scrolling?

Try like this.
private int oldScrollYPostion = 0; // inside your class
mScrollView.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
#Override
public void onScrollChanged() {
if (mScrollView.getScrollY() > oldScrollYPostion) {
fab.hide();
} else if (mScrollView.getScrollY() < oldScrollYPostion || mScrollView.getScrollY() <= 0) {
fab.show();
}
oldScrollYPostion = mScrollView.getScrollY();
}
});
You are using Floating action inside the scroll view tag. take it out of scroll view.
Use something like this:

navigationUsernameText = (TextView)findViewById(R.id.nav_drawer_username);
navigationUsernameText.setText(PreferenceConnector.readString(aiContext,

Here is how it should be and how it is when no scrolling menu
Here is how it looks like after scrolling down
i'm in serious problem. I'm trying to get EditText from tab1 in Tabhost, but it keeps giving me error:
Attempt to invoke virtual method 'android.view.View android.widget.LinearLayout.findViewById(int)' on a null object reference.
I have tried my code in many many different ways without any success!
Here is my Code :
final LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View control_layout = inflater.inflate(R.layout.control_layout,null,false);
TabHost tbhst = (TabHost)control_layout.findViewById(R.id.tabHost);
tbhst.setup();
TabHost.TabSpec tb1 = tbhst.newTabSpec("TAB 1");
TabHost.TabSpec tb2 = tbhst.newTabSpec("TAB 2");
TabHost.TabSpec tb3 = tbhst.newTabSpec("TAB 3");
tb1.setContent(R.id.tab1);
tb2.setContent(R.id.tab2);
tb3.setContent(R.id.tab3);
tb1.setIndicator("CMD");tb2.setIndicator("Chat");tb3.setIndicator("Control");tbhst.addTab(tb3);tbhst.addTab(tb2);tbhst.addTab(tb1);
LinearLayout gff = (LinearLayout)tbhst.findViewById(R.id.ggf);
FrameLayout tbs_content = (FrameLayout)gff.findViewById(android.R.id.tabcontent);
LinearLayout tbs1 = (LinearLayout)tbs_content.findViewById(R.id.tab1);
final EditText command_resualt_box = (EditText) tbs1.findViewById(R.id.editText5);
UPDATE :
as #popvitsj said maybe i'm making mistake but i tried to change it in layout/control.xml, but it gives me another different error and here is a Screenshot :

NOTE : this code is giving an error you can take look on screenshot above.
FrameLayout tbs_content = (FrameLayout)gff.findViewById(android.R.id.tabcontent);
LinearLayout tbs1 = (LinearLayout)tbs_content.findViewById(R.id.tab1);
The second of these lines gives the NullPointerException. So tbs_content is null, because it fails to load it on the first line.
It looks like you made a mistake specifying the id: android.R.id.tabcontent should most likely be R.id.tabcontent.
android.R is the R-class for the system resources. R is usually your own generated class (unless you import android.R).
I am trying to find a way to animate changing the alpha of a FrameLayout's foreground drawable, but i cant seem to find a way of doing it.
If someone could point me in the right direction as to how i should go about this i would be hugely grateful.
The relevant code is below:

And the java code that i use to change the alpha of the foreground:
fabMain.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean expanded = fabMenu.toggle();
mainActivity.getDimShadowDrop().setForeground(getResources().getDrawable(R.drawable.dim_shadow_shape_light));
mainActivity.getDimShadowDrop().getForeground().setAlpha(180);
if (expanded){
((MainActivity)getActivity()).replaceFragment(new RecordFragment(), R.id.slideUpPanel, false);
slidingUpPanelLayout.expandPanel();
defaultColor = getResources().getColor(R.color.recordDefaultColor);
}
}
});
Instead of the typical way you do it with an Animation which is from 0 to 1 you use 0 to 255. Something like this will pulse the Foreground of a CardView.
public static void pulseForeground(CardView view, long duration) {
ObjectAnimator animator = ObjectAnimator.ofInt(view.getForeground(), "alpha", 0, 255);
animator.setDuration(duration);
animator.setStartDelay(20);
animator.setRepeatMode(Animation.REVERSE);
animator.setRepeatCount(Animation.INFINITE);
animator.start();
}
