回答1:

you can set the Background image in Tab widget as

tabHost.getTabWidget().getChildAt(0).setBackgroundResource(R.drawable.home_h);
tabHost.getTabWidget().getChildAt(1).setBackgroundResource(R.drawable.live);
tabHost.getTabWidget().getChildAt(2).setBackgroundResource(R.drawable.camera);
tabHost.getTabWidget().getChildAt(3).setBackgroundResource(R.drawable.profile);
tabHost.getTabWidget().getChildAt(4).setBackgroundResource(R.drawable.Messege);

create the image as other four like Their Top 20% as Transparent and middle camera create as your Curve base . you will achieve your goal as this.

Like this where grey part is Transparency part.

I'm doing something like this:

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:orientation="vertical"
android:layout_width="match_parent" 
android:layout_height="match_parent">

    <TabWidget 
            android:id="@android:id/tabs" 
            android:layout_width="match_parent" 
            android:layout_height="0dp"
            android:tabStripEnabled="false"/>

    <FrameLayout
        android:id="@android:id/tabcontent"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/btn1" />

        <ImageView 
            android:id="@+id/btn1"        
            android:layout_alignParentBottom="true"      
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toLeftOf="@+id/btn2"
            android:src="@drawable/ic_launcher"/>

        <ImageView 
            android:id="@+id/btn2"
            android:layout_alignParentBottom="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toLeftOf="@+id/btn3"
            android:src="@drawable/ic_launcher"/>

         <ImageView 
            android:id="@+id/btn3"
            android:layout_alignParentBottom="true"
            android:layout_centerHorizontal="true"
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:src="@drawable/ic_launcher"/>     

         <ImageView 
            android:id="@+id/btn4"
            android:layout_toRightOf="@+id/btn3"
            android:layout_alignParentBottom="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher"/>     

        <ImageView 
            android:id="@+id/btn5"
            android:layout_toRightOf="@+id/btn4"
            android:layout_alignParentBottom="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher"/>                                         

</RelativeLayout>
</TabHost>

I'm get rid off build in TabWidget and setting up my own by LinearLayout. Later you just need to set onClick function in main Tab Activity.

Like:

public void onClick(View v)
    {
            switch(v.getId())
            {
                    case R.id.btn1: 
                            tabHost.setCurrentTab(0);
                            break;
                    case R.id.btn2:
                            tabHost.setCurrentTab(1);
                            break;
                    case R.id.btn3:
                            tabHost.setCurrentTab(2);
                            break;
                    case R.id.btn4:
                            tabHost.setCurrentTab(3);
                            break;
                    case R.id.btn5:
                            tabHost.setCurrentTab(4);
                            break;
            }
    }
