toast大家都很熟，不多说。直接上图上代码。

 

 　　　　　　

具体代码如下：

main.xml:

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:gravity="center"
  android:orientation="vertical"
  android:padding="5dip" >

  <button
    android:id="@+id/btnsimpletoast"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="默认" >
  </button>

  <button
    android:id="@+id/btnsimpletoastwithcustomposition"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="自定义显示位置" >
  </button>

  <button
    android:id="@+id/btnsimpletoastwithimage"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="带图片" >
  </button>

  <button
    android:id="@+id/btncustomtoast"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="完全自定义" >
  </button>

  <button
    android:id="@+id/btnruntoastfromotherthread"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="其他线程" >
  </button>

</linearlayout>

custom.xml:

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/lltoast"
  android:layout_width="wrap_content"

  android:background="#ffffffff"
  android:orientation="vertical" >

  <textview
    android:id="@+id/tvtitletoast"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_margin="1dip"
    android:background="#bb000000"
    android:gravity="center"
    android:textcolor="#ffffffff" />

  <linearlayout
    android:id="@+id/lltoastcontent"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginbottom="1dip"
    android:layout_marginleft="1dip"
    android:layout_marginright="1dip"
    android:background="#44000000"
    android:orientation="vertical"
    android:padding="15dip" >

    <imageview
      android:id="@+id/tvimagetoast"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_gravity="center" />

    <textview
      android:id="@+id/tvtexttoast"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"

      android:paddingleft="10dip"
      android:paddingright="10dip"
      android:textcolor="#ff000000" />
  </linearlayout>

</linearlayout>
