Android Toast 总结(五种用法)

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:layout_height="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:gravity="center"
            android:paddingLeft="10dip"
            android:paddingRight="10dip"
            android:textColor="#ff000000" />
    </LinearLayout>
