• 动画综合练习(延迟进入+页面向导+文本框抖动)


    1、activity_welcome.xml(界面刚载入进入欢迎界面的布局)

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/ll_welcome_root"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" 
        android:background="@drawable/welcome_back"
        android:gravity="center_horizontal|bottom">
        <ProgressBar
            android:id="@+id/progressBar1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" 
            android:indeterminateDrawable="@anim/image_progress"
            android:indeterminateDuration="500"/>
    </LinearLayout>
    2、image_progress.xml(欢迎界面启动后,屏幕底部会有一个旋转的载入进度条)

    <?xml version="1.0" encoding="utf-8"?

    > <rotate xmlns:android="http://schemas.android.com/apk/res/android" android:fromDegrees="0" android:toDegrees="360" android:pivotX="50%" android:pivotY="50%" android:drawable="@drawable/progess2"/>


    3、WelcomeActivity.java

    package com.atguigu.l10_app2;
    
    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.os.Handler;
    import android.os.Message;
    import android.view.animation.AlphaAnimation;
    import android.view.animation.Animation;
    import android.view.animation.Animation.AnimationListener;
    import android.widget.LinearLayout;
    /**
     * 欢迎界面
     *
     */
    public class WelcomeActivity extends Activity {
    	private LinearLayout ll_welcome_root;
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_welcome);
    		
    		ll_welcome_root = (LinearLayout) findViewById(R.id.ll_welcome_root);
    		//调用启动动画效果
    		showAnimation();
    	}
    	
    	//接受消息、处理消息
    	private Handler handler = new Handler(new Handler.Callback() {
    		@Override
    		public boolean handleMessage(Message msg) {
    			if(msg.what==1) {
    				//接受到消息后。启动还有一个界面
    				startActivity(new Intent(WelcomeActivity.this, Guide1Activity.class));
    			}
    			return true;
    		}
    	});
    	/**
    	 * 显示动画
    	 */
    	private void showAnimation() {
    		//设置图片背景透明度
    		AlphaAnimation animation = new AlphaAnimation(0.0f, 1.0f);
    		animation.setDuration(2000);
    		//设置动画监听
    		animation.setAnimationListener(new AnimationListener() {
    			
    			@Override
    			public void onAnimationStart(Animation animation) {
    				
    			}
    			
    			@Override
    			public void onAnimationRepeat(Animation animation) {
    				
    			}
    			
    			@Override
    			public void onAnimationEnd(Animation animation) {
    				//发送延迟的空消息
    				handler.sendEmptyMessageDelayed(1, 1000);
    			}
    		});
    		//欢迎界面的启动动画效果界面
    		ll_welcome_root.startAnimation(animation);
    	}
    }
    
    4、然后进入第一个向导界面如图


    先看向导界面1的布局文件

    activity_guide1.xml

    <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="com.atguigu.l10_app2.Guide1Activity" >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="第一个设置" />
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true"
            android:text="下一步" 
            android:onClick="next"/>
    </RelativeLayout>
    
    Guide1Activity.java(代码作用是启动界面向导二,以及显示向导界面1和2的切换效果)

    package com.atguigu.l10_app2;
    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    
    public class Guide1Activity extends Activity {
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_guide1);
    	}
    
    	public void next(View v) {
    		startActivity(new Intent(this, Guide2Activity.class));
    		//显示一个界面切换的动画
    		overridePendingTransition(R.anim.anim_right_in, R.anim.anim_left_out);
    	}
    }
    
    anim_left_out.xml(当前页面向左滑动)

    <?xml version="1.0" encoding="utf-8"?

    > <translate xmlns:android="http://schemas.android.com/apk/res/android" android:fromXDelta="0%" android:toXDelta="-100%" android:duration="1000"> </translate>

    anim_right_in.xml(下一张页面向左滑动进入到当前页面)

    <?xml version="1.0" encoding="utf-8"?

    > <translate xmlns:android="http://schemas.android.com/apk/res/android" android:fromXDelta="100%" android:toXDelta="0%" android:duration="1000"> </translate>


    5、接下来看向导页面2的布局



    activity_guide2.xml(向导界面二,上图的布局文件)

    <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="com.atguigu.l10_app2.Guide1Activity" >
    
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="第二个设置" />
    
        <Button
            android:id="@+id/button2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:layout_alignParentRight="true"
            android:onClick="next"
            android:text="下一步" />
    
        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBaseline="@+id/button2"
            android:layout_alignBottom="@+id/button2"
            android:layout_alignParentLeft="true"
            android:text="上一步" 
            android:onClick="pre"/>
    
    </RelativeLayout>
    Guide2Activity.java(向导二的java代码。作用是点击下一张。和点击上一张。显示页面切换的滑动效果)

    package com.atguigu.l10_app2;
    
    import android.app.Activity;
    import android.content.Intent;
    import android.os.Bundle;
    import android.view.View;
    
    public class Guide2Activity extends Activity {
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_guide2);
    	}
    	
    	public void next(View v) {
    		startActivity(new Intent(this, MainActivity.class));
    	}
    	
    	public void pre(View v) {
    		finish();
    		
    		//显示一个界面切换的动画
    		overridePendingTransition(R.anim.anim_left_in, R.anim.anim_right_out);
    	}
    }
    

    另外附上点击返回上一张界面的xml文件

    anim_left_in.xml

    <?xml version="1.0" encoding="utf-8"?>
    <translate
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:fromXDelta="-100%" 
        android:toXDelta="0%"
        android:duration="500">
    </translate>
    
    anim_right_out.xml

    <?

    xml version="1.0" encoding="utf-8"?

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



    6、接下来进入主界面了(这个效果是文本框抖动效果)

    activity_main.xml(先看主页面的布局文件)

    <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="com.atguigu.l10_app2.MainActivity" >
    
        <EditText
            android:id="@+id/et_main_number"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/hello_world" />
    
        <Button
            android:id="@+id/button1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/et_main_number"
            android:text="提交" 
            android:onClick="submit"/>
    
    </RelativeLayout>
    
    MainActivity.java

    package com.atguigu.l10_app2;
    
    import android.app.Activity;
    import android.os.Bundle;
    import android.view.View;
    import android.view.animation.Animation;
    import android.view.animation.AnimationUtils;
    import android.widget.EditText;
    
    public class MainActivity extends Activity {
    
    	private EditText et_main_number;
    	
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    		et_main_number = (EditText) findViewById(R.id.et_main_number);
    	}
    	
    	public void submit(View v) {
    		//水平振动
    		Animation animation = AnimationUtils.loadAnimation(this, R.anim.shake);
    		et_main_number.startAnimation(animation);
    	}
    }
    

    实现水平震动的须要以下xml文件支持

    cycle_6.xml

    <?xml version="1.0" encoding="utf-8"?>
    <cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
        android:cycles="6"/>

    shake.xml

    <?xml version="1.0" encoding="utf-8"?>
    <translate
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:fromXDelta="0.1"
        android:toXDelta="1.0"
        android:duration="500"
        android:interpolator="@anim/cycle_6">
        <!-- 配置文件中不能有f出现 -->
    </translate>
