View above DrawerLayout is not becoming visible even after .bringToFront and View.VISIBLE

Following is my layout file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/activity_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<LinearLayout
android:id="#+id/progress_layout"
android:visibility="gone"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ProgressBar
android:id="#+id/horizontal_progress_bar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:indeterminateOnly="false"
android:max="10000"
android:maxHeight="15dip"
android:minHeight="10dip" />
</LinearLayout>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Add content here -->
<RelativeLayout
android:id="#+id/content_fragments_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"></RelativeLayout>
</FrameLayout>
<ListView
android:id="#+id/menu_items_list"
android:layout_width="280dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>
By default progress_layout visibility is GONE. Whenever user clicks on a menu item, I want to show the progress bar on top of(overlay) existing fragment and start the background operation. To show this layout currently I call following method:
public void showProgress(int progress){
LinearLayout progressLayout = (LinearLayout) findViewById(R.id.progress_layout);
ProgressBar progressBar = (ProgressBar) findViewById(R.id.horizontal_progress_bar);
progressBar.setProgress(progress);
progressLayout.bringToFront();
progressLayout.setVisibility(View.VISIBLE);
LinearLayout dashboardLayout = (LinearLayout) findViewById(R.id.activity_layout);
dashboardLayout.requestLayout();
dashboardLayout.invalidate();
}
But still I don't see my progress bar on top of my fragment.
Please let me know how can I get this to work.

In your xml file the LinearLayout with id: progress_layout is in gone mode. So you need add this line in showProgress method:
progressLayout.setVisibility(View.VISIBLE);
I hope this will help you.

I think the simple solution is move progress bar to on top of your view
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/activity_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Add content here -->
<RelativeLayout
android:id="#+id/content_fragments_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"></RelativeLayout>
</FrameLayout>
<ListView
android:id="#+id/menu_items_list"
android:layout_width="280dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:dividerHeight="0dp" />
</android.support.v4.widget.DrawerLayout>
<!-- move your progress_layout to end of this xml, it will be on top of view -->
<LinearLayout
android:id="#+id/progress_layout"
android:visibility="gone"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ProgressBar
android:id="#+id/horizontal_progress_bar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:indeterminateOnly="false"
android:max="10000"
android:maxHeight="15dip"
android:minHeight="10dip" />
</LinearLayout>
And now you only set visibility = VISIBLE when you want show it.

DrawerLayout overlapped by another view

I implemented a Navigation Drawer as explained here https://developer.android.com/training/implementing-navigation/nav-drawer.html
I inserted the DrawerLayout xml code snippet just below the tag and above the others app views.
At runtime when open the Navigation Drawer the behind view is still clickable and I cant use the Navigation Drawer
I think I've to adjust the xml layout but I don't know how..
<?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="#drawable/bg_sky">
<com.example.sp1d3r.weatheralarm.CustomDrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView

NavigationDrawer blocks other button on the activity

I'm working on the UI of my app and I'm facing a problem when I implement the Navigation Drawer. As you can see here, I have some buttons to manage my Media Player, these are not responding to my clicks when I implement the Navigation Drawer (working fine without Navigation Drawer).
I think the problem is coming from my XML file because there are no changing when I delete the implementation in Java.
Here are my XML sheets :
main_activity.xml
<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=".MyActivity">
<fragment
android:id="#+id/fragments"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.example.ilan.myapplication.fragments.FragmentHome" >
</fragment>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="Buffering"
android:id="#+id/tV_Buffering"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true" />
<include
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_weight="1"
layout="#layout/player_controls"
android:layout_alignParentBottom="true"/>
<include
layout="#layout/navigation_drawer_main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
Note that I put the Navigation Drawer in the end to have it to cover the all activity.
navigation_drawer_main_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#FFFFFF"/>
</android.support.v4.widget.DrawerLayout>
player_controls.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="100dp"
android:id="#+id/button_play_pause"
android:layout_toStartOf="#+id/tV_Buffering"
android:background="#drawable/bouton_play"
android:layout_centerInParent="true"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:id="#+id/button_stop"
android:layout_toRightOf="#id/button_play_pause"
android:layout_centerInParent="true"
android:layout_marginLeft="20dp"/>
</RelativeLayout>
Well, if anyone has any idea from where this come from it would be awesome, thanks !

To use a DrawerLayout, position your primary content view as the first child with width and height of match_parent and no layout_gravity. Add drawers as child views after the main content view and set the layout_gravity appropriately. Drawers commonly use match_parent for height with a fixed width. Check out the documentation of google regarding to DrawerLayout : https://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html.
Your primary content should put inside DrawerLayout instead of including the DrawerLayout inside your RelativeLayout.
For your case, you could try to implement it this way instead:
main_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MyActivity">
<fragment
android:id="#+id/fragments"
class="com.example.ilan.myapplication.fragments.FragmentHome"
android:layout_width="match_parent"
android:layout_height="match_parent">
</fragment>
<TextView
android:id="#+id/tV_Buffering"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:text="Buffering"
android:textAppearance="?android:attr/textAppearanceSmall"/>
<include
layout="#layout/player_controls"
android:layout_width="match_parent"
android:layout_height="100dp"
android:layout_alignParentBottom="true"
android:layout_weight="1"/>
</RelativeLayout>
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#FFFFFF"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"/>
</android.support.v4.widget.DrawerLayout>

can anyone help me??

The order of how you define things in the xml decide how they appear on the screen, also determines which view appears above or below which other view. For a Nav Drawer, The layout should be something like this :
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:font="http://schemas.android.com/apk/res/com.teewe.client"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- This LinearLayout is the layout for your activity. Replace with FrameLayout -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:orientation="vertical"
android:padding="#dimen/padding_from_screen_edges" >
</LinearLayout>
<!--The last view that you include, shows up in your drawer. In this case, everything inside this RelativeLayout shows up in the drawer. -->
<RelativeLayout
android:id="#+id/drawerRelativeLayout"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#fff" >
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_above="#id/nowPlayingLayout"
android:choiceMode="singleChoice"
android:divider="#color/light_gray"
android:dividerHeight="1dp" />
</RelativeLayout>
</android.support.v4.widget.DrawerLayout>

Contents not showing up in DrawerLayout after adding a progress bar in Android

I am new to android so I am trying to make a simple application. Everything is fine until I try to add a progress bar.
(Sorry for showing the images with a hyperlink as I don't have enough reputation to post images)
How it looks like:
screenshot here
What I wanted to have is something like:
draft layout here
main_activity before adding a progress bar:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/credit_label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="24dp"
android:paddingTop="8dp"
android:paddingBottom="8dp"
android:text="#string/credit" >
</TextView>
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"/>
(The closing tag for DrawerLayout is at the end but I don't know why it is not showing up if I start a new line with it)
Then I want to add a progress bar under the textView which acts as a label. After I insert a ProgressBar element in main_activity.xml, a progress bar appeared in the middle of the screen but that's not what I exactly wanted.
Afterwards I tried to use a LinearLayout element to wrap up the TextView and ProgressBar, trying to arrange and display them accordingly, with the xml file shown below:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/credit_label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="24dp"
android:paddingTop="8dp"
android:paddingBottom="8dp"
android:text="#string/credit" >
</TextView>
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:id="#+id/credit_progress"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="80dp" />
</LinearLayout>
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"/>
But the progress bar is not showing up, it turns out that only the TextView label is showing up. Upon interchanging the order of the TextView and ProgressBar elements, an error will occur stating that I am casting PorgressBar to TextView, but I don't know how this happenes with the following line of code:
TextView credit = (TextView) findViewById(R.id.credit_label);
I read another topic (here) in stackoverflow, stating that there can only be 3 elements in the drawerlayout, I tried to use the LinearLayout to wrap up all stuffs except the left_drawer list, so I tried the following version:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/credit_label"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="24dp"
android:paddingTop="8dp"
android:paddingBottom="8dp"
android:text="#string/credit" >
</TextView>
<ProgressBar
style="?android:attr/progressBarStyleHorizontal"
android:id="#+id/credit_progress"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingBottom="80dp" />
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"/>
This time it didn't stop unop starting the application, but the FrameLayout consists of the fragment displaying the expandable list will shows nothing (white blank in that place). I am very frustrated and I don't know what the problems are, hence finally came here and hope to get some help. Thanks a lot!
