Custom Image Title scaling with Screen-width

Question

Im trying to make a custom Titlebar for my App, which is no more, than an Image.

Totally custom example:

My Goal is to have the Size of the Picture scale by the Screen-width of the Display.

I already tried removing the TitleBar, and just placing an ImageView, but still a Titlebar, with App-Name and Icon got created...

Answer 1

在manifest的<application>标记中设置此属性以删除标题栏

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

Answer 2

Set your activity like this in manifest.xml

   <activity
        android:name=".YourActivity"
        android:configChanges="keyboardHidden|orientation|keyboard" // this is hide keyboard
        android:theme="@android:style/Theme.Translucent.NoTitleBar" > // hide the title bar
    </activity>
