删除活动中的标题栏也会删除图像

Question

I have this code in my layout class requestWindowFeature(Window.FEATURE_NO_TITLE) to remove the title bar. It is working fine as it is removed the title bar. But unfortunately, it also removes the images I put inside the activity.

I am using constraint layout and I already infer constraint. I also tried putting inside my manifest on application level the android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen" code, but whenever I run the app, it says application has stopped.

Please help. Thank you.

Answer 1

To hide title bar for specific activity do this set these lines in onCreate on the activity class

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getSupportActionBar().setDisplayShowTitleEnabled(false);

and in activity layout

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="@android:color/transparent"
    app:popupTheme="@style/AppTheme.PopupOverlay" />

and remove AppBarLayout

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay"/>

Put these lines in your activity - onCreate method -

super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

Then add android:theme="@style/AppTheme.NoActionBar"

in your manifest file look like -

<activity
            android:name=".EmailValidation"
            android:configChanges="keyboardHidden|screenSize|orientation"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme.NoActionBar"
            android:windowSoftInputMode="adjustPan|stateHidden" />

I hope this will be help you.
