Android 活动转换未设置动画

我一直在学习材料转换，遵循指南。我有一个小测试应用程序，我正在尝试这个

我的活动代码如下所示：

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.transition.Slide;
import android.view.View;

public class TransitionsHome extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_transitions_home);
    }

    public void slide(View view){
        //Create a slide object, then set it as the exit transition
        Slide slide = new Slide();
        slide.setDuration(1000);
        getWindow().setExitTransition(slide);

        startActivity(new Intent(this, SlideActivity.class));
    }

startActivity(intent,ActivityOptions.makeSceneTransitionAnimation(this).toBundle());

我有一个按钮，按下时会调用

slide（）

问题是，它正在更改为正确的活动，但根本没有动画。为什么这不起作用？

像这样调用

StartActivity

：

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.transition.Slide;
import android.view.View;

public class TransitionsHome extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_transitions_home);
    }

    public void slide(View view){
        //Create a slide object, then set it as the exit transition
        Slide slide = new Slide();
        slide.setDuration(1000);
        getWindow().setExitTransition(slide);

        startActivity(new Intent(this, SlideActivity.class));
    }

startActivity(intent,ActivityOptions.makeSceneTransitionAnimation(this).toBundle());

---

按如下方式调用

StartActivity

：

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.transition.Slide;
import android.view.View;

public class TransitionsHome extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_transitions_home);
    }

    public void slide(View view){
        //Create a slide object, then set it as the exit transition
        Slide slide = new Slide();
        slide.setDuration(1000);
        getWindow().setExitTransition(slide);

        startActivity(new Intent(this, SlideActivity.class));
    }

startActivity(intent,ActivityOptions.makeSceneTransitionAnimation(this).toBundle());

@uestcfei那么我必须膨胀XML并调用

overridePendingAnimation

和所有东西才能向后兼容吗？@uestcfei那么我必须膨胀XML并调用
