我有一个 Activity ,即 Material Design Drawer,以及当用户单击抽屉选项时从 Activity java 文件中调用的一些 fragment 。 问题在于 fragment 布局与 Activity 标题栏重叠,匹配所有屏幕,而不是位于 Activity 内部。 在 AndroidStudio 预览中, fragment 内容设置正确:
这是我的源代码: - fragment_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin">
<EditText
android:id="@+id/subjectSelector"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text"
android:hint="Write subject initials"/>
<Button
android:id="@+id/queryButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end"
style="@style/Base.Widget.AppCompat.Button.Borderless"
android:text="Search"
android:layout_alignBottom="@+id/subjectSelector"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
<ProgressBar
android:id="@+id/progressBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_centerVertical="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/subjectSelector"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="@+id/subjectName"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/subjectTeachers"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/subjectDescription"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<TextView
android:id="@+id/subjectCredits"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
</ScrollView>
</RelativeLayout>
抽屉.java
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Fragment newFragment;
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
if (id == R.id.nav_timetable) {
newFragment = new TimetableMainMenu();
} else if (id == R.id.nav_notifications) {
newFragment = new NotificationsMainMenu();
} else if (id == R.id.nav_schedule) {
newFragment = new ScheduleMainMenu();
} else if (id == R.id.nav_class_availability) {
newFragment = new ClassAvailabilityMainMenu();
} else if (id == R.id.nav_subject_info) {
newFragment = new SubjectInfoMainMenu();
} else newFragment = null;
if (newFragment != null) {
transaction.replace(R.id.main_menu_fragment_container, newFragment);
transaction.addToBackStack(null);
} else {
Toast.makeText(MainMenuActivity.this, "Not implemented yet", Toast.LENGTH_SHORT).show();
}
transaction.commit();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
- MainMenu.xml(抱歉,我无法将其更新为代码格式)
- app_bar_main_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.upc.fib.racopocket.MainMenuActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main_menu" />
</android.support.design.widget.CoordinatorLayout>
content_main_menu.xml
<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/main_menu_fragment_container" android:layout_width="match_parent" android:layout_height="match_parent" />
我该如何解决这个问题?
最佳答案
我得到了答案,这只是一件愚蠢的事情。在 content_main_menu.xml 上,框架布局与所有屏幕匹配,所以我只需要留下 actionBarSize 的 marginTop。这是新的 content_main_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/main_menu_fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"/>
