android - Android实现CoordinatorLayout和Framelayout

我在应用程序主活动布局中使用以下代码

<?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.keyhan_soft.gps.MainActivity">

    <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"/>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:src="@android:drawable/ic_dialog_email"/>

</android.support.design.widget.CoordinatorLayout>

如您所见，我在<include layout="@layout/content_main"/>行中包含了片段布局，但这是静态方式，我如何用动态FrameLayout解决方案替换这种静态方式？
我想以编程方式添加片段

最佳答案

您可以尝试以下方法来执行FragmentTransaction来替换Fragment布局中的content_main。以下方法用于FragmentTransaction。

方法：

public void pushFragments(Fragment fragment, boolean shouldAdd, String tag) {
    FragmentManager manager = getSupportFragmentManager();//Use this line for FragmentManager , if you are in Activity
    //FragmentManager manager = getActivity().getSupportFragmentManager();//Use this line for FragmentManager , if you are in Fragment
    FragmentTransaction ft = manager.beginTransaction();

    //manager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);//Uncomment this line if you don't want to maintain Fragment Backsack
    ft.replace(R.id.content_main, fragment, tag);
    if (shouldAdd) {
        ft.addToBackStack(tag); //add fragment in backstack
    }
    ft.commit();
}

我给出了如何做FragmentTransaction的例子。

YourFragment.java

public class YourFragment extends BaseFragment {
    private View rootView;

    public YourFragment() {
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        rootView = inflater.inflate(R.layout.layout_your_fragment, container, false);
        return rootView;
    }
}

例：

pushFragments(new YourFragment(),
 true, // true --> add Fragment in backstack else false
"YourFragment"); // Fragment tag which help to find your fragment

希望对您有所帮助。
