Element of listview out of bounds(visually) because of round edges

I am making an android app using Java in android studio. I have defined drawable background for listview with round edges. But last shown row is visually out of listview container. It is not just the line separating it from next record but also "-" symbol can be halfway out of the container. The app looks like this
is there a way to keep content inside the bounds?

It's happening bcz your background is different to listview and list view is always a square layout.
So basically, use cardview and set app:cardCornerRadius="" to cardview and list view set inside of cardview.
like this.
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:cardCornerRadius="10dp"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="YOUR_BACKGROUND"
/>
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</RelativeLayout>
</androidx.cardview.widget.CardView>
OR
The other option is to use a round corner layout.

and set list view inside of any RoundCornerLayout.

Optimize code for Android with multiple layouts

I am creating an Android Application having two layouts. All layouts have some common features like the top part is same and the only difference is at the bottom part.
Currently I have created two separate java files for two layouts. And I have simply copied the code which implements similar functionality like buttons etc
The part seen is the pic is the top part of the layout which is same in both the layouts;
Is there any way with which I can optimize the functionality by having reusable code

In my opinion this is helpful using <include> in your main layout.
STEP:
you have to create one XML file for your common layout.
topbar.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width=”match_parent”
android:layout_height="wrap_content"
android:background="#color/titlebar_bg">
<ImageView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/gafricalogo" />
</FrameLayout>
like this way now you have to include this XML file to where you have to require.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal">
<include layout="#layout/topbar"/>
...
</LinearLayout>

I think this tab bar can also be used for this..

Customize position of handle of sliding drawer

I had researched many sources and tried but still cannot move the position of handle from center to right.
<SlidingDrawer
content >
<ImageButton <-- this is handle
android:id="#+id/handle" <-- i want to customize position
android:layout_width="50px"
android:layout_height="60px"
android:background="#drawable/icon_other" />
<LinearLayout
android:id="#+id/content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_others"
android:orientation="vertical" >
//content
</LinearLayout>
</SlidingDrawer>
So what to do to customize the position?
Please give opinion. Thanks

Use a TableLayout. This works similar to a HTML Table concept, allowing you to define rows and columns where to place buttons and other components.
If you don't want to use a table layout for the entire screen, you should be able to nest the layout within another....

Is it possible to include a MapView as an element of another activity?

Just as the title says...I want to include a MapView inside of another activity. For instance, I want the MapView to take up half of the screen, and below that, include some other widgets - text fields, buttons, whatever. I have been tinkering with it, but so far I have been unsuccessful - the map does take up only half the screen, but no widgets show up.
Any clues? Is this possible, or is the Google Map integration strictly using the map as a full screen?

Please post your xml layout!
You are just doing it wrong. :-D
A mapview will work like any other widget. I strongly believe there is a mistake in your layout.
This one will work for instance!
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/h1"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<CheckBox
android:text="Satellite"
android:id="#+id/satellite"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</CheckBox>
<ImageView
android:id="#+id/image"
android:layout_width="75dip"
android:layout_height="75dip"
android:layout_marginRight="6dip"
android:src="#drawable/uoicon" />
</LinearLayout>
<com.google.android.maps.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:apiKey="0zDdYFYf6Ir2W-NuiHPLAoFjsq0nmqRhPfzjY3A"/>
</LinearLayout>

Just a guess but you're using a LinearLayout to contain the MapView and other widgets but you forgot to set the orientation to vertical? The default for LinearLayout is horizontal.
It came to mind because it's something I've done 2 or 3 times myself. Totally confusing as effectively the other widgets 'disappear' off the right-hand side of the screen. It eventually got engrained in my mind and I always make sure to explicitly specify orientation now when I use LinearLayout.

How to set height for the listview that created dynamically through java code?

I 'm trying to set the height of the listview which has been created through java code dynamically. I'm using 3 listviews(one below another) in a scrollview(to avoid hiding of lists). If i use scroll view, i cannot see all the list items of the listviews.Is there any idea to set height for those 3 list views through java coding in android? Any help is really appreciated and thanks in advance...

Don't put ListViews in ScrollViews! In Detail Information from the developers of Listview is available in the talk World of ListViews
It is possible to make the three ListViews share the space on the Screen by using the layoutWeight parameter.
Make a layout like this (you can also use code for that):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView android:id="#+id/listView1" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="1"></ListView>
<ListView android:id="#+id/listView2" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="1"></ListView>
<ListView android:id="#+id/listView3" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="1"></ListView>
</LinearLayout>
Here each ListView takes a third of the available space (all weights set to 1).
To set the layoutWeight in code use this line as example:
listview1.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1f));
