Answer 1

IF you need to disable the status bar from your java code, then you can do this:

Window win = getWindow();
win.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

Simple solution, just add android:theme=”@android:style/Theme.NoTitleBar.Fullscreen” to your manifest, for example:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="de.vogella.android.temperature"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".Convert"
                  android:label="@string/app_name"
                   android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
    <uses-sdk android:minSdkVersion="9" />

</manifest>
