一、style样式：
1、 // 结合移动和透明渐变的动画
<style name="anim_view"> <item name="@android:windowEnterAnimation">@anim/anim_in</item> <item name="@android:windowExitAnimation">@anim/anim_out</item> </style>
anim_in.xml 文件：
<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" > <translate android:duration="1" android:fromXDelta="0" android:fromYDelta="0" android:toXDelta="0" android:toYDelta="85" /> <translate android:duration="350" android:fillAfter="true" android:fromXDelta="0" android:fromYDelta="0" android:toXDelta="0" android:interpolator="@android:anim/decelerate_interpolator" android:toYDelta="-105" /> <alpha android:duration="100" android:fromAlpha="0" android:toAlpha="1" /> <translate android:duration="80" android:fillAfter="true" android:fromXDelta="0" android:fromYDelta="0" android:startOffset="350" android:toXDelta="0" android:toYDelta="20" /></set>
anim_out.xml 文件：
<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" > <alpha android:duration="800" android:fromAlpha="1" android:toAlpha="0" /></set>
2、 // 动画缩放效果 <style name="anim_view_scale"> <item name="@android:windowEnterAnimation">@anim/lite_toast_enter</item> <item name="@android:windowExitAnimation">@anim/lite_toast_exit</item> </style>
lite_toast_enter.xml 文件：
<?xml version="1.0" encoding="utf-8"?><!-- 进入动画 --><scale xmlns:android="http://schemas.android.com/apk/res/android" android:duration="@android:integer/config_longAnimTime" android:fromXScale="0" android:toXScale="1" android:fromYScale="0" android:toYScale="1" android:pivotX="50%" android:pivotY="50%" android:interpolator="@android:anim/decelerate_interpolator" />
lite_toast_exit.xml 文件：
<?xml version="1.0" encoding="utf-8"?><!-- 出去动画 --><scale xmlns:android="http://schemas.android.com/apk/res/android" android:duration="@android:integer/config_longAnimTime" android:fromXScale="1" android:toXScale="0" android:fromYScale="1" android:toYScale="0" android:pivotX="50%" android:pivotY="50%" android:interpolator="@android:anim/decelerate_interpolator" />
二、自定义Toast类文件
第一种方法是：
package com.bright.shuiyin.toast;import android.annotation.SuppressLint;import android.content.Context;import android.graphics.PixelFormat;import android.os.Handler;import android.view.Gravity;import android.view.View;import android.view.WindowManager;import android.view.WindowManager.LayoutParams;import android.widget.Toast;@SuppressLint("ShowToast")/** 带动画的自定义Toast */ /** 显示时长 */ boolean mShowTime; long mShowTimeShort = 2000; long mShowTimeLong = 3500; /** 显示的 Y 轴所在的位置 */ int mShowAtY = 140; /** 是否正在显示 */ boolean mIsShow; WindowManager mWdm; View mToastView; LayoutParams mParams; /** 动画资源 */ int mStyleId; /** * @param context * @param text * 提示信息 * @param showTime * 提示显示的时长，false为短(2000)、true为长(3500) */ public MyCToast(Context context, String text, boolean showTime, int styleId) { // 记录Toast的显示长短类型 this.mShowTime = showTime; // 记录当前Toast的内容是否已经在显示 this.mIsShow = false; this.mWdm = (WindowManager) context .getSystemService(Context.WINDOW_SERVICE); // 通过Toast实例获取当前android系统的默认Toast的View布局 this.mToastView = Toast.makeText(context, text, Toast.LENGTH_SHORT) .getView(); this.mStyleId = styleId; setParams(); } /** 参数的添加：添加动画 */ private void setParams() { mParams = new WindowManager.LayoutParams(); mParams.height = WindowManager.LayoutParams.WRAP_CONTENT; mParams.width = WindowManager.LayoutParams.WRAP_CONTENT; mParams.format = PixelFormat.TRANSLUCENT; mParams.windowAnimations = mStyleId; // 设置进入退出动画效果 mParams.type = WindowManager.LayoutParams.TYPE_TOAST; mParams.flags = WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE; mParams.gravity = Gravity.CENTER_HORIZONTAL; mParams.y = mShowAtY; } /** 显示：addView */ public void show() { // 如果Toast没有显示，则开始加载显示 if (!mIsShow) { mIsShow = true; // 将其加载到windowManager上 mWdm.addView(mToastView, mParams); cancelShow(); } } /** 获取 Toast 对象 */ public static MyCToast makeText(Context context, String text, boolean showTime, int styleId) { MyCToast result = new MyCToast(context, text, showTime, styleId); return result; } /** 退出显示：removeView */ public void cancelShow() { if (mToastView != null) { new Handler().postDelayed(new Runnable() { @Override public void run() { mWdm.removeView(mToastView); mIsShow = false; } }, (long) (mShowTime ? 3500 : 2000)); // 这里设置显示的时长，之后执行 removeView } } }
第二种方法是：
package com.bright.shuiyin.toast;import java.lang.reflect.Field;import android.content.Context;import android.view.WindowManager;import android.widget.Toast;/** * 使用反射自定义带动画的Toast */public class MyToast extends Toast { public MyToast(Context context) { super(context); } /** * 调用有动画的Toast * @param context * @param text * @param duration * @param 自定义的动画id * @return */ public static Toast makeTextAnim(Context context, CharSequence text, int duration, int styleId) { Toast toast = makeText(context, text, duration); toast.setText(text); toast.setDuration(duration); try { Object mTN = null; mTN = getField(toast, "mTN"); if (mTN != null) { Object mParams = getField(mTN, "mParams"); if (mParams != null && mParams instanceof WindowManager.LayoutParams) { WindowManager.LayoutParams params = (WindowManager.LayoutParams) mParams; params.windowAnimations = styleId; } } } catch (Exception e) { e.printStackTrace(); } return toast; } /** * 反射字段 * * @param object * 要反射的对象 * @param fieldName * 要反射的字段名称 * @return * @throws NoSuchFieldException * @throws IllegalAccessException */ private static Object getField(Object object, String fieldName) throws NoSuchFieldException, IllegalAccessException { Field field = object.getClass().getDeclaredField(fieldName); if (field != null) { field.setAccessible(true); return field.get(object); } return null; }}
三、使用：
第一种的使用：
MyCToast.makeText(MyToastActivity.this, "MyCToast !", false, R.style.anim_view_scale).show();
第二种的使用：
MyToast.makeTextAnim(MyToastActivity.this, "自定义缩放Toast", 0, R.style.anim_view_scale).show();
