Question

In my application i am working with canvas. I am drawing on canvas. I put canvas color as white. When my app open the canvas is visible along with above status bar.
But i want my canvas should take the full screen. means that Notification status bar should disapear when i run that app bt not the title bar(bcz i m using some custom title bar)
How can i do that?

By using below code i gave custom title,

requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);

getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title);

Now i am trying to hide status bar using below code in activity-

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

and in AndroidManifest.xml

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

But it shows force close.
Give me a way how to do that?

Answer 1

You can’t use Window.FEATURE_CUSTOM_TITLE after setting Theme.NoTitleBar. It’s enough to use just this theme. Do not set all these flags in code.

EDIT: Seems I misunderstood your question. I read it again carefully and now I see you’re asking about Android 2.x and its notification bar. Your onCreate() method should look like this:

public void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);

    setContentView(R.layout.name);

    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.custom_title);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

You mustn’t set Theme.NoTitleBar or Theme.NoTitleBar.Fullscreen for this activity. Just use the default Theme or don’t specify any theme at all.
