第13天~

转场动画-老师说也不要花太多时间

一样先通通关掉+第3个

建activity_main.xml的button

用内建-转场=就是跳画面

1-要有一个画面出一个画面入
2-会有manager

要新增第2页

建 activity_main.xml的button

button也是要onClick

onClick负责做跳页-

explode 缩放

fade 变淡

slide_right 右拨

目前程序码:

package com.huang.mytransition;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.transition.Transition;
import android.transition.TransitionInflater;
import android.view.View;

public class MainActivity extends AppCompatActivity {

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

        //建立动画
      Transition explode = TransitionInflater.from(this).inflateTransition(android.R.transition.explode);
      Transition
        //指定执行时间点




    }

    public void onClick(View view) {
    }
}

slide_bottom 由下往上拨-灰色看不到要看截图

package com.huang.mytransition;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.transition.Transition;
import android.transition.TransitionInflater;
import android.view.View;

public class MainActivity extends AppCompatActivity {

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

        //建立动画
      Transition explode = TransitionInflater.from(this).inflateTransition(android.R.transition.explode);
      Transition slide = TransitionInflater.from(this).inflateTransition(android.R.transition.slide_bottom);
        //指定执行时间点

        
    }

    public void onClick(View view) {
    }
}

指定执行时间点.一个进来.一个出去

package com.huang.mytransition;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.transition.Transition;
import android.transition.TransitionInflater;
import android.view.View;

public class MainActivity extends AppCompatActivity {

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

        //建立动画
      Transition explode = TransitionInflater.from(this).inflateTransition(android.R.transition.explode);
      Transition slide = TransitionInflater.from(this).inflateTransition(android.R.transition.slide_bottom);

      //指定执行时间点

        getWindow().setEnterTransition(explode);
        getWindow().setEnterTransition(explode);

    }

    public void onClick(View view) {


    }
}

跳页的反应-

public void onClick(View view) {

        Intent it = new Intent();
        it.setClass(MainActivity.this,Page2.class);
        startActivity(it);


    }

目前完整程序码:

package com.huang.mytransition;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.transition.Transition;
import android.transition.TransitionInflater;
import android.view.View;

public class MainActivity extends AppCompatActivity {

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

        //建立动画
      Transition explode = TransitionInflater.from(this).inflateTransition(android.R.transition.explode);
      Transition slide = TransitionInflater.from(this).inflateTransition(android.R.transition.slide_bottom);

      //指定执行时间点

        getWindow().setEnterTransition(explode);
        getWindow().setEnterTransition(explode);

    }

    public void onClick(View view) {

        Intent it = new Intent();
        it.setClass(MainActivity.this,Page2.class);
        startActivity(it);


    }
}

目前第2页还没有写-

改 startActivity(it);这句加参数

public void onClick(View view) {

        Intent it = new Intent();
        it.setClass(MainActivity.this,Page2.class);
        //startActivity(it);
        startActivity(it,
                ActivityOptionsCompat.makeSceneTransitionAnimation(MainActivity.this).toBundle());
    }

不过效果一样

来写Page2.java程序码:

从Page1贴过来

要改掉反红变 Page2.java

package com.huang.mytransition;

import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityOptionsCompat;

import android.content.Intent;
import android.os.Bundle;
import android.transition.Transition;
import android.transition.TransitionInflater;
import android.view.View;

public class Page2 extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_page2);

        //建立动画
        Transition explode = TransitionInflater.from(this).inflateTransition(android.R.transition.explode);
        Transition slide = TransitionInflater.from(this).inflateTransition(android.R.transition.slide_bottom);

        //指定执行时间点

        getWindow().setEnterTransition(explode);
        getWindow().setEnterTransition(slide);

    }

    public void onClick(View view) {

        Intent it = new Intent();
        it.setClass(Page2.this, MainActivity.class);
        //startActivity(it);
        startActivity(it,
                ActivityOptionsCompat.makeSceneTransitionAnimation(Page2.this).toBundle());
    }
}

再加入fade 虽然我是觉得看起来一样

MainActivity.java

package com.huang.mytransition;

import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityOptionsCompat;

import android.content.Intent;
import android.os.Bundle;
import android.transition.Transition;
import android.transition.TransitionInflater;
import android.view.View;

public class MainActivity extends AppCompatActivity {

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

        //建立动画
      Transition explode = TransitionInflater.from(this).inflateTransition(android.R.transition.explode);
      Transition slide = TransitionInflater.from(this).inflateTransition(android.R.transition.slide_bottom);
        Transition fade = TransitionInflater.from(this).inflateTransition(android.R.transition.fade);

      //指定执行时间点

        getWindow().setEnterTransition(fade);
        getWindow().setEnterTransition(fade);

    }

    public void onClick(View view) {

        Intent it = new Intent();
        it.setClass(MainActivity.this,Page2.class);
        //startActivity(it);
        startActivity(it,
                ActivityOptionsCompat.makeSceneTransitionAnimation(MainActivity.this).toBundle());
    }



    }

Page2.java

package com.huang.mytransition;

import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityOptionsCompat;

import android.content.Intent;
import android.os.Bundle;
import android.transition.Transition;
import android.transition.TransitionInflater;
import android.view.View;

public class Page2 extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_page2);

        //建立动画
        Transition explode = TransitionInflater.from(this).inflateTransition(android.R.transition.explode);
        Transition slide = TransitionInflater.from(this).inflateTransition(android.R.transition.slide_bottom);
        Transition fade = TransitionInflater.from(this).inflateTransition(android.R.transition.fade);

        //指定执行时间点

        getWindow().setEnterTransition(fade);
        getWindow().setEnterTransition(fade);

    }

    public void onClick(View view) {

        Intent it = new Intent();
        it.setClass(Page2.this, MainActivity.class);
        //startActivity(it);
        startActivity(it,
                ActivityOptionsCompat.makeSceneTransitionAnimation(Page2.this).toBundle());
    }
}
