（1）布局文件layout

package com.lc.toastdialog;

import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

	private Button button1;
	private Button button2;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		button1 = (Button) this.findViewById(R.id.button1);
		button2 = (Button) this.findViewById(R.id.button2);
		/*
		 * 普通的Toast
		 */
		button1.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				Toast.makeText(MainActivity.this, 普通的Toast,
						Toast.LENGTH_SHORT).show();
			}
		});
		/*
		 * 自定義的Toast
		 */
		button2.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				// 找到toast這個layout
				View layout = LayoutInflater.from(MainActivity.this).inflate(
						R.layout.toast, null);
				// 對toast文件中的textView設置值
				TextView textView = (TextView) layout.findViewById(R.id.text);
				textView.setText(hello world!);

				Toast toast = new Toast(MainActivity.this);
				toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
				toast.setDuration(Toast.LENGTH_SHORT);
				toast.setView(layout);
				toast.show();
			}
		});

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
