		((LinearLayout) mContainer).setGravity(gravity
				| Gravity.CENTER_VERTICAL);

		mTextView.setText(message);

		mFadeInAnimation.setDuration(ANIMATION_DURATION);

		mContainer.startAnimation(mFadeInAnimation);

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mbContainer"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

使用方法:

MyMsgBox m = new MyMsgBox(arg0.getContext(), 5000,
                        Gravity.BOTTOM);
