Toast给用户提示时就显得有点不搭这个软件的风格,这时自定义Toast就派上用场了。这次我将在上一次的基础上,带领大家来完成全屏加载转圈动画和自定义Toast。下面给出今天的两张完成后的效果图:

的背景图,给它转圈动画,并将次ImageView加载到自定义对话框中就可以了。自定义Toast则跟自定义对话框有点类似,加载自定义view,修改其属性就ok了。下面给出代码:

布局文件:main.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"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
  
    <Button
android:id="@+id/button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="Click"
android:text="弹出自定义对话框"
/>
     <Button
android:id="@+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/button"
android:onClick="Click"
android:text="弹出加载对话框"
/>
    <Button
android:id="@+id/button2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:onClick="Click"
android:layout_below="@id/button1"
android:text="弹出自定义Toast"
/>
  
</RelativeLayout>

 

自己写的封装的Tools,也是最重要的,这个大家直接复制就可以使用,只需把图片替换成你们的图片:

}
