Appcompatactivity Remove title bar and EditText pop-up soft keyboard to obscure input box problem

1. appcompatactivity Remove the title bar

To get rid of the title bar here, it is important to note that Appcompactactivity is inherited from activity. However, appcompactactivity according to view the online information, in fact, it seems to have no title bar, the title bar shown above is a Actionbar control (PS: That is, the title bar part is a control, the control function is also relatively strong), So appcompactactivity can add related returns, many similar function buttons to the control, and if you don't add those buttons it looks like a title bar.

Therefore, many on-line to configure the value folder in the Style.xml file or in the Androidmanifest.xml file to modify the theme attribute value is not effective to remove the title bar. These methods only apply to classes that are written to inherit from activity.

Then inherit from the Appcompactactivity class, add the following first line of code in the Oncreateview to effectively hide the title bar, add two lines can occupy full screen function. (PS: After the landlord to test the normal browsing sliding interface can be hidden, but in some cases, such as the interface has a video playback function, click Full-screen playback, exit full screen, the title bar may not be hidden. However, in general, the hidden function is not a problem)

Getsupportactionbar (). Hide ();   // Hide title bar GetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_ fullscreen);   // realize full screen, hide the phone on the top of the time-related information display

2. edittext pop-up soft keyboard obscures input box issues

The specific explanation excerpt from a netizen blog (PS: Convenient after their own inspection, the original link )

The corresponding activity configuration in Androidmanifest.xml:android:windowsoftinputmode= "Adjustresize"(PS: or Replace with "Statevisible|adjustresize", This will force eject floppy disk )

<?XML version= "1.0" encoding= "Utf-8"?><Manifestxmlns:android= "Http://schemas.android.com/apk/res/android" Package= "Com.example.helloworld">    <uses-permissionAndroid:name= "Android.permission.INTERNET" />    <ApplicationAndroid:allowbackup= "true"Android:icon= "@mipmap/ic_launcher"Android:label= "@string/app_name"Android:supportsrtl= "true"Android:theme= "@style/apptheme">        <ActivityAndroid:name=". Main2activity "android:windowsoftinputmode= "Adjustresize">            <Intent-filter>                <ActionAndroid:name= "Android.intent.action.MAIN" />                <categoryAndroid:name= "Android.intent.category.LAUNCHER" />            </Intent-filter>        </Activity>        <ActivityAndroid:name=". Mainactivity "></Activity>    </Application></Manifest>
