<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".MainActivity" >    <Button        android:id="@+id/button1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_alignParentTop="true"        android:layout_marginLeft="104dp"        android:layout_marginTop="70dp"        android:text="普通的Toast" />    <Button        android:id="@+id/button2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignRight="@+id/button1"        android:layout_below="@+id/button1"        android:layout_marginTop="50dp"        android:text="自訂的Toast" /></RelativeLayout>

（2）需要彈出的Toast布局檔案

（3）類的檔案

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;@Overrideprotected 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() {@Overridepublic void onClick(View v) {Toast.makeText(MainActivity.this, "普通的Toast",Toast.LENGTH_SHORT).show();}});/* * 自訂的Toast */button2.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// 找到toast這個layoutView layout = LayoutInflater.from(MainActivity.this).inflate(R.layout.toast, null);// 對toast檔案中的textView設定值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();}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {getMenuInflater().inflate(R.menu.main, menu);return true;}}
