Android 自定义Toast

最近开发的一个Android小程序，使用Toast给用户提示信息，但是使用系统默认的Toast显示的字体偏小，于是通过自定义布局文件修改Toast字体大小，同时为了使自定义的Toast与系统默认的Toast样式一致，给自定义视图进行了一定的修饰，效果如下：

Eclipse中项目结构：

各个文件代码如下：

MainActivity.java

public class MainActivity extends Activity
{
	@Override
	public void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		initToast();
	}

	private void initToast()
	{
		View toastRoot = getLayoutInflater().inflate(R.layout.toast, null);
		TextView message = (TextView) toastRoot.findViewById(R.id.message);
		message.setText("My Toast");

		Toast toastStart = new Toast(this);
		toastStart.setGravity(Gravity.BOTTOM, 0, 10);
		toastStart.setDuration(Toast.LENGTH_LONG);
		toastStart.setView(toastRoot);
		toastStart.show();
	}

}

toast.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@drawable/toast_frame"
    >
	<TextView 
		android:id="@+id/message"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:textAppearance="@style/TextAppearance.Small"
        android:textColor="@color/bright_foreground_dark"
        android:shadowColor="#BB000000"
        android:shadowRadius="2.75"
	  	/>
