我目前遇到的问题是尽管在我的片段中将所有布局设置为match_parent
,除非明确占用屏幕宽度,例如带有大量文本字符串的TextView
,布局最终将宽度包裹在其内容中。
这是XML:
MainActivity.xml
<android.support.v4.widget.DrawerLayout
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:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
tools:context="es.esports_app.MainActivity">
<android.support.v7.widget.Toolbar
android:id="@+id/mainToolbar"
android:minHeight="?attr/actionBarSize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/notQuiteBlack"
app:layout_constraintTop_toTopOf="parent">
</android.support.v7.widget.Toolbar>
<android.support.constraint.ConstraintLayout
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="0dp"
android:fillViewport="true"
app:layout_constraintBottom_toTopOf="@+id/navigationViewLayoutWrapper"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="@+id/mainToolbar">
<!-- Where fragment content is inserted -->
<FrameLayout
android:id="@+id/Container"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</FrameLayout>
</android.support.constraint.ConstraintLayout>
<include
android:id="@+id/navigationViewLayoutWrapper"
layout="@layout/main_bottom_navigation_bar" />
</android.support.constraint.ConstraintLayout>
<ListView
android:id="@+id/navigation_drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111" />
series_wrapper.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TabLayout
android:id="@+id/seriesSectionTabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/notQuiteBlack"
app:tabTextColor="@color/mdGrey400"
app:tabIndicatorColor="@color/white"
app:tabSelectedTextColor="@color/white"
app:tabMode="scrollable"
app:tabGravity="fill"
app:tabMaxWidth="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent">
</android.support.design.widget.TabLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="YAY"
app:layout_constraintTop_toBottomOf="@id/seriesSectionTabs"/>
</android.support.constraint.ConstraintLayout>
添加片段的位置
holder.eventSeriesWrapper.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
AppCompatActivity appCompatActivity = (AppCompatActivity) view.getContext();
Fragment fragment = new SeriesWrapperFragment();
Bundle bundle = new Bundle();
bundle.putInt("seriesID", eventSeries.id);
bundle.putInt("seriesLength", eventSeries.seriesLength);
fragment.setArguments(bundle);
appCompatActivity.getFragmentManager().beginTransaction().replace(R.id.Container, fragment).addToBackStack(null).commit();
}
});
The above code results in this
如果我将TextView文本设置为跨越屏幕宽度的非常长的字符串:
这正是我希望标签布局看起来的样子,但我不想将TextView或类似内容定义为屏幕宽度,以便以这种方式显示它。 / p>
我也尝试在onCreateView中设置片段的布局参数,但是,UI与第一张图片中的相同
系列包装碎片OnCreateView
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.series_wrapper, container, false);
view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
if(this.getArguments() != null){
this.seriesID = this.getArguments().getInt("seriesID");
this.seriesLength = this.getArguments().getInt("seriesLength");
}
else{
this.seriesID = 0;
this.seriesLength = 0;
}
return view;
}
如果需要更多代码段或图片,请询问。
如果有人能帮助我理解为什么会发生这种情况,我们将不胜感激。
谢谢。

这种情况正在发生,因为match_parent
在ConstraintLayout
中不起作用。您需要在设计视图中使用match_constraint
,或者您可以通过设置高度/宽度来设置match_constraint
= 0dp
标签布局集android:layout_width="0dp"
示例,其行为与ConstraintLayout
中的match_parent类似
<android.support.design.widget.TabLayout
android:id="@+id/seriesSectionTabs"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="@color/notQuiteBlack"
app:tabTextColor="@color/mdGrey400"
app:tabIndicatorColor="@color/white"
app:tabSelectedTextColor="@color/white"
app:tabMode="scrollable"
app:tabGravity="fill"
app:tabMaxWidth="0dp"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent">
