效果

步骤

• 自定义toast的样式文件

• 将布局转换为view
• 创建toast对象，并设置view即可

源码

1、MainActivity

Toast toast = new Toast(this);
LayoutInflater inflator = LayoutInflater.from(this);
View view = inflator.inflate(R.layout.toast_layout, null);
toast.setView(view);
toast.setDuration(Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();

2、toast的样式文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="@drawable/toastsytle" 
    android:gravity="center">
    
    <RelativeLayout 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
    
            <ImageView 
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/image"
                android:src="@drawable/ic_launcher"/>           
        
            <TextView 
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="提示信息"
                android:textSize="20sp"
                android:textColor="#fff"
                android:layout_centerInParent="true"
                android:layout_toRightOf="@+id/image"/>
    
    </RelativeLayout>
</LinearLayout>

这里background="@drawable/toastsytle" 设置了一个背景圆角效果。setGravity可设置显示位置。

3、toastsytle.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="#21211d"/>

    <corners android:topLeftRadius="10dp"  
             android:topRightRadius="10dp"  
             android:bottomRightRadius="10dp"  
             android:bottomLeftRadius="10dp"/>
</shape>

补充

在默认效果上添加图片

Toast toast = Toast.makeText(this, "显示对话框", Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);     
LinearLayout linearLayout = (LinearLayout) toast.getView();
ImageView imageView = new ImageView(this);  
imageView.setImageResource(R.drawable.ic_launcher);
linearLayout.addView(imageView,0);
toast.show();
