Answer 1

Put this one line before setContentView

requestWindowFeature(Window.FEATURE_NO_TITLE);
//setContentView(R.layout.main_activity);

And if you want full screen then use below code:

requestWindowFeature(Window.FEATURE_NO_TITLE);

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//setContentView(R.layout.main_activity);

Yeah, This one also. Just put theme on AndroidManifest.xml

<activity
   android:name="MainActivity"
   android:label="@string/app_name"
   android:screenOrientation="portrait"
   android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"/>

Add this lines in your manifest file

    <activity
        android:name="activity name"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
    </activity>

also use layout.xml like this.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<RelativeLayout
    android:id="@+id/top"
    android:layout_width="fill_parent"
    android:layout_height="70dp"
    android:background="@drawable/top_home" >

    <Button
        android:id="@+id/back"
        android:layout_width="90dp"
        android:layout_height="34dp"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:layout_marginLeft="15dp"
        android:background="@drawable/about_back_selector"
        android:onClick="@string/back_click"
        android:text="@string/back"
        android:textColor="#ffffff" />

    <ImageView
        android:id="@+id/logo"

Answer 3

have you set your layout container width to match_parent or fill_parent ?

<LinearLayout
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
 ...
</LinearLayout>
