您好,这是一个Dialog Activity。我想删除空格。我该怎么做?不幸的是,我被困住了。谢谢你提前......
<style name="ThemeDialog" parent="Theme.AppCompat.Light.Dialog">
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">false</item>
</style>
<activity
android:name=".Activities.AboutActivity"
android:label="@string/hakkinda"
android:theme="@style/ThemeDialog"
android:screenOrientation="portrait"/>
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_about);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
}

尝试将ThemeDialog样式更改为:
<style name="ThemeDialog" parent="@style/Theme.AppCompat.Light.NoActionBar">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
<item name="android:backgroundDimEnabled">true</item>
</style>
也许在您的活动根布局中,您应该添加paddingTop和paddingBottom而不是硬编码高度。

片段将为标题栏保留该空间。要删除它,您需要覆盖onCreateDialog
:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
// request a window without the title
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return dialog;
}

在你的&#34; activity_about&#34;文件,更改'android:paddingTop'
的值,直到获得所需的效果(我将其更改为0dp):
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="0dp" >
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>

只需从您的mainactivity xml中删除paddingTop
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
