一、style样式:
1、 // 移动和透明渐变结合的动画
<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、 // 缩放效果的动画
<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、自定义的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")
/** 自定义带动画的Toast */
public class MyCToast {
/** 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();
