1.创建一个自己想要显示Toast风格的XML如下代码（toast_xml.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="horizontal"     android:padding="8dp"                  android:background="#DAAA"    android:id="@+id/toast_layout_root">    <ImageView     android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_marginRight="8dp"    android:id="@+id/iv"    /><TextView android:id="@+id/text"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:textColor="#FFF"    /></LinearLayout>

2.封装一个Toast共同类，当然也可以直接在activity运用，那么我是用共通类，当然只是简单的封装：

import com.sbr.activity.R;import android.annotation.SuppressLint;import android.content.Context;import android.view.Gravity;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import android.widget.TextView;import android.widget.Toast;@SuppressLint("ResourceAsColor")public class ToastCommom {private static ToastCommom toastCommom;private Toast toast;private ToastCommom(){}public static ToastCommom createToastConfig(){if (toastCommom==null) {toastCommom = new ToastCommom();}return toastCommom;}/** * 显示Toast * @param context * @param root * @param tvString */public void ToastShow(Context context,ViewGroup root,String tvString){View layout = LayoutInflater.from(context).inflate(R.layout.toast_xml,root);TextView text = (TextView) layout.findViewById(R.id.text);ImageView mImageView = (ImageView) layout.findViewById(R.id.iv);mImageView.setBackgroundResource(R.drawable.ic_launcher);text.setText(tvString);text.setTextColor(R.color.aqua);toast = new Toast(context);toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);toast.setDuration(Toast.LENGTH_LONG);toast.setView(layout);toast.show();}}

3.创建一个Activity去引用该共通类：

import com.sbr.commonView.ToastCommom;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.widget.Button;public class ToastActivity extends Activity {private Button mbutton;private ToastCommom toastCommom;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.toast_buton);toastCommom = ToastCommom.createToastConfig();mbutton = (Button) findViewById(R.id.btn);mbutton.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubtoastCommom.ToastShow(ToastActivity.this, (ViewGroup)findViewById(R.id.toast_layout_root), "你好");}});}}

好了，一个简单的自定义toast显示就完成了；当然万变不离其宗，都是类似的做法。
