我正在尝试实现一个 BottomNavigationView 并在内容中实现一个 ScrollView。一切都很好，但是当 BottomNavigationView 使用 ScrollView 打开 FrameLayout 时，就不起作用了
这是我的activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.panel.roubook.activities.NewBook">
<FrameLayout
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="@+id/bottom_navigation"
android:layout_alignParentTop="true">
</FrameLayout>
<android.support.design.widget.BottomNavigationView
android:id="@+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:itemBackground="@color/colorAccent"
app:itemIconTint="@color/colorPrimary"
app:itemTextColor="@color/colorPrimary"
app:menu="@menu/navigation_items" />
</RelativeLayout>
这是我的框架
<?xml version="1.0" encoding="utf-8"?>

在我的 MainActivity.java
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fragmentManager = getFragmentManager();
final FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
BottomNavigationView bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_explorer:
return true;
case R.id.action_ready:
return true;
case R.id.action_account:
fragmentTransaction.replace(android.R.id.content , new Account());
fragmentTransaction.commit();
return true;
}
return true;
}
});
}
当我按下帐户时，屏幕会更改为帐户，但 ScrollView 覆盖 BottomNavigationView 并且无法使用 BottonNavigationView 的其他按钮
抱歉我的英语不好。
最佳答案
将 android.R.id.content 替换为 R.id.content 因为 android.R.id.content 不是您的 ID您在 XML 中定义的 FrameLayout，它是其他 View 的 id。
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_explorer:
return true;
case R.id.action_ready:
return true;
case R.id.action_account:
fragmentTransaction.replace(R.id.content , new Account());
fragmentTransaction.commit();
return true;
}
return true;
}
});
