Java 为活动外的imageview设置动画，并将一个片段从底部带入活动：Android

我有一个主要活动，它有一个从顶部滑入的imageview

我想以2秒的延迟淡出此图像视图。 然后立即让一个片段从底部滑入主活动

如何延迟淡出图像视图？

在xml或新java类中，在哪里定义片段？

如何设置片段的动画？

MainActivity.java

public class MainActivity extends AppCompatActivity {

LinearLayout ml;
Animation uptodown;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_screen);
    ml = (LinearLayout) findViewById(R.id.ml);
    uptodown = AnimationUtils.loadAnimation(this,R.anim.uptodown);
    ml.setAnimation(uptodown);

}

activity_main.xml

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:background="@drawable/backgroundcolour">
<LinearLayout
    android:id="@+id/ml"
    android:layout_width="match_parent"
    android:layout_height="400dp"
    android:orientation="vertical">
    <ImageView
       <!-- my imageview -->    
    />
</LinearLayout>

在xml末尾添加框架布局，如：

<FrameLayout
android:id="@+id/frame_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

添加幻灯片动画，如：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
    android:duration="1000"
    android:fromYDelta="100%"
    android:toYDelta="0" />
</set>

FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
                        android.support.v4.app.Fragment newFragment;
                        newFragment = new YourFragment();
                        transaction.replace(R.id.frame_layout, newFragment);
                        transaction.commit();

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
    android:duration="1000"
    android:fromYDelta="100%"
    android:toYDelta="0" />
</set>

FrameLayout frameLayout = findViewById(R.id.frame_layout);
    Animation slide_up = AnimationUtils.loadAnimation(getApplicationContext(),
                R.anim.slide_up);
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        Animation fadeOut = new AlphaAnimation(1, 0);
                        fadeOut.setInterpolator(new AccelerateInterpolator()); //and this
                        fadeOut.setStartOffset(1000);
                        fadeOut.setDuration(1000);
                        ml.setAnimation(fadeOut);
                        frameLayout.setAnimation(slide_up);
                    }
                },2000);
