我是学Android的新手。我长话短说。我收到了底部提到的错误。我通过XML添加了一个片段。我一直在寻找解决方案，但到目前为止没有一个成功。我哪里做错了？
如果我能找到解决办法那就好。我能解释一下为什么会这样吗？

修复你的detail_activity.xml将class替换为android：name

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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="match_parent"
    tools:context=".DetailActivity">

    <fragment
        android:name="com.example.workout.WorkoutDetailFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
    />

</androidx.constraintlayout.widget.ConstraintLayout>

修改DetailActivity.xml标记片段，如下所示

<fragment android:name="com.example.workout.WorkoutDetailFragment"
    android:id="@+id/frag"
    android:layout_weight="1"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

使用OnFragmentInteractionListener实现您的主要活动，并按照以下代码更改xml

public class MainActivity extends AppCompatActivity implements WorkoutDetailFragment.OnFragmentInteractionListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.detail_activity);
}

@Override
public void onFragmentInteraction(Uri uri) {

}}

你的XML

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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="match_parent"
tools:context=".MainActivity">

<fragment
    android:id="@+id/fragment"
    android:name="com.example.myapplication.WorkoutDetailFragment"
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

如果仍然无法执行，请共享片段类文件

  • 此错误主要是因为您没有为片段容器给予id。*
    在DetailActivity.xml之前
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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="match_parent"
tools:context=".DetailActivity">

<fragment
    class="com.example.workout.WorkoutDetailFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
/>

字符串

要解决这个问题，请提供一个像这样的唯一标识符
在DetailActivity.xml之后

<?xml version="1.0" encoding="utf-8"?>
    <androidx.constraintlayout.widget.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="match_parent"
    tools:context=".DetailActivity">
    
<fragment
     android:id="@+id/uniqueid" //this was missing
     class="com.example.workout.WorkoutDetailFragment"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
/>

请为您的片段指定唯一的id并尝试。

<fragment
    android:id="@+id/fragId"
    class="com.example.workout.WorkoutDetailFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
 />
