1、首先是右→左进入动画 、slide_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"><translateandroid:duration="800"android:fromXDelta="200%"android:toXDelta="0" />
</set>

左→右退出动画、slide_right.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"><translateandroid:duration="800"android:fromXDelta="0"android:toXDelta="200%" />
</set>

2、activity 的xml代码

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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:orientation="vertical"tools:context=".MainActivity"><LinearLayoutandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:orientation="vertical"><TextViewandroid:id="@+id/mainks"android:layout_width="200dp"android:layout_height="100dp"android:gravity="center"android:text="开始"/><TextViewandroid:id="@+id/maingb"android:layout_width="200dp"android:layout_height="100dp"android:gravity="center"android:text="关闭"/></LinearLayout><android.support.design.widget.CoordinatorLayoutandroid:id="@+id/clRootView"android:layout_width="match_parent"android:layout_height="match_parent"></android.support.design.widget.CoordinatorLayout></FrameLayout>

3、activity实现方法

boolean ifshowfragment = false;

抽屉fragment进入方法yhox

private void showAboutFragment() {getSupportFragmentManager().beginTransaction().disallowAddToBackStack().setCustomAnimations(R.anim.slide_left, R.anim.slide_right).add(R.id.clRootView, MyFragment.newInstance(), MyFragment.TAG).commit();ifshowfragment = true;
}

抽屉fragment退出方法

public void onFragmentDetached(String tag) {FragmentManager fragmentManager = getSupportFragmentManager();Fragment fragment = fragmentManager.findFragmentByTag(tag);if (fragment != null) {fragmentManager.beginTransaction().disallowAddToBackStack().setCustomAnimations(R.anim.slide_left, R.anim.slide_right).remove(fragment).commitNow();}ifshowfragment = false;
}

activity返回键退出动画方法：

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {if (keyCode == KeyEvent.KEYCODE_BACK&& event.getAction() == KeyEvent.ACTION_DOWN) {if (ifshowfragment) {onFragmentDetached(MyFragment.TAG);return true;}}return super.onKeyDown(keyCode, event);
}

半屏导航fragment实现方法

 

1、添加导航view依赖

compile 'com.android.support:design:28.0.0'

 

2、activity代码：

private NavigationView navigationView;
private DrawerLayout drawerLayout;

navigationView = (NavigationView)findViewById(R.id.navigation_view);
drawerLayout = (DrawerLayout)findViewById(R.id.drawer);

 

drawerLayout.openDrawer(navigationView);
drawerLayout.closeDrawer(navigationView);

效果：

全屏                                                                                               半屏
