从右向左滑动Android动画

Question

嘿,我正在开发一个Android项目,需要Android WebView上的幻灯片动画.当用户从左向右滑动时,它将移动到新页面,当它从右向左执行时,它将移动到上一页.但Android只有两个转换,即slide_out_right和slide_in_left.使用它们之后,从左到右的滑动工作是完美的,但另一个看起来很奇怪(相反).

任何解决方案.我希望slide_out_left动画更精确.

Answer 1

请阅读此博客文章,其中包含过渡动画的示例,我已经包含以下代码:

调用活动

package com.as400samplecode;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity implements OnClickListener{

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

  Button nextActivity = (Button) findViewById(R.id.nextActivity);
  nextActivity.setOnClickListener(this);

 }

 public void onClick(View v) {

  switch (v.getId()) {
  case R.id.nextActivity:
   Intent nextActivity = new Intent(this,NextActivity.class);
   startActivity(nextActivity);
   //push from bottom to top
   overridePendingTransition(R.anim.push_up_in, R.anim.push_up_out);
   //slide from right to left
   //overridePendingTransition(R.anim.slide_in_right, R.anim.slide_out_left);
   break;

   // More buttons go here (if any) ...

  }
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.activity_main, menu);
  return true;
 }

}

调用活动的布局资源

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
 android:layout_height="match_parent" tools:context=".MainActivity"
 android:background="@color/ivory"> 
 <Button android:id="@+id/nextActivity" android:layout_width="match_parent"
  android:layout_height="wrap_content" android:layout_alignParentLeft="true"
  android:layout_alignParentTop="true" android:layout_marginTop="15dp"
  android:text="Go to Next Activity" /> 
</RelativeLayout>

被称为活动

package com.as400samplecode;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class NextActivity extends Activity implements OnClickListener{

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

        Button previousActivity = (Button) findViewById(R.id.previousActivity);
        previousActivity.setOnClickListener(this);

    }

 public void onClick(View v) {

  switch (v.getId()) {
  case R.id.previousActivity:
   finish();
   //push from top to bottom
   overridePendingTransition(R.anim.push_down_in, R.anim.push_down_out);
   //slide from left to right
   //overridePendingTransition(R.anim.slide_in_left, R.anim.slide_out_right);
   break;

   // More buttons go here (if any) ...

  }
 }


}

被调用活动的布局资源

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
 android:layout_height="match_parent" tools:context=".NextActivity"
 android:background="@color/khaki">

 <Button android:id="@+id/previousActivity" android:layout_width="match_parent"
  android:layout_height="wrap_content" android:layout_alignParentLeft="true"
  android:layout_alignParentTop="true" android:layout_marginTop="15dp"
  android:text="Go to Previous Activity" />

</RelativeLayout>

Answer 2

您可以将自己的动画样式作为这样的xml文件(将其放在anim文件夹中):

左到右:

  <set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
        <translate android:fromXDelta="-100%" android:toXDelta="0%"
         android:fromYDelta="0%" android:toYDelta="0%"
         android:duration="500"/>
  </set>

右到左:

    <set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
     <translate
        android:fromXDelta="0%" android:toXDelta="100%"
        android:fromYDelta="0%" android:toYDelta="0%"
        android:duration="500" />
   </set>

你可以在持续时间设置你自己的值,也许这取决于手机型号的动画效果,如果它看起来不好,可以尝试一些值.

然后你可以在你的活动中调用它:

     Intent animActivity = new Intent(this,YourStartAfterAnimActivity.class);
      startActivity(nextActivity);

      overridePendingTransition(R.anim.your_left_to_right, R.anim.your_right_to_left);

Answer 3

用于滑动活动(旧的和新的)相同的方向:

left_in.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromXDelta="-100%"
    android:toXDelta="0%"
    android:interpolator="@android:anim/decelerate_interpolator"
     />

right_in.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromXDelta="100%"
    android:toXDelta="0%"
    android:interpolator="@android:anim/decelerate_interpolator"
     />

left_out.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromXDelta="0%"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:toXDelta="-100%" />

right_out.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromXDelta="0%"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:toXDelta="100%" />

startActivity转换:

overridePendingTransition(R.anim.right_in, R.anim.left_out);

onBackPressed转换:

overridePendingTransition(R.anim.left_in, R.anim.right_out);

Answer 4

我找到的最简单的方法就是使用Activity Transitions,这很容易

onCreate要在动画中运行的活动中的覆盖方法:

@Override
  protected void onCreate(Bundle savedInstanceState) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      Slide slide = new Slide();
      slide.setSlideEdge(Gravity.RIGHT);

      getWindow().setEnterTransition(slide);
    }
    super.onCreate(savedInstanceState);
  }

然后使用转换(而不是activity.startActivity(context))启动它:

activity.startActivity(starter, ActivityOptions.makeSceneTransitionAnimation(activity).toBundle());

要使用this.finish()使用动画关闭活动,请使用下面的代码:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
      getActivity().finishAfterTransition();
    } else getActivity().finish();

Answer 5

看到这个链接..你可以在这里看到这么多种动画,只需将xml复制到你的res/anim文件夹并使用如下所示..

listView.setAnimation(AnimationUtils.loadAnimation(MainActivity.this,R.anim.slide_in_right));
