启动不透明片段

Question

通过

按下按钮从活动启动片段。显示此片段，但也显示并启动女巫的活动内容。我希望该片段是不透明的。

launchFragmentButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            FragmentManager manager = getSupportFragmentManager();
            DisplayFragment fragmentDisplay = new DisplayFragment();
            FragmentTransaction fragmentTransaction = manager.beginTransaction();
            fragmentTransaction.replace(R.id.display_container, fragmentDisplay);
            fragmentTransaction.addToBackStack(null);
            fragmentTransaction.commit();
        }
    });

在片段布局中.xml 将背景设置为父节点。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    <!-- set here your background -->
    android:background="@color/main_bg"
    tools:context="fragmentsMain.HomeFragment">
</RelativeLayout >
