1.建立一個自己想要顯示Toast風格的XML如下程式碼（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.封裝一個Toast共同類，當然也可以直接在activity運用，那麼我是用共通類，當然只是簡單的封裝：

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;
	}
	
	/**
	 * 顯示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.建立一個Activity去引用該共通類：

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;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.toast_buton);
		toastCommom = ToastCommom.createToastConfig();
		mbutton = (Button) findViewById(R.id.btn);
		mbutton.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				toastCommom.ToastShow(ToastActivity.this, (ViewGroup)findViewById(R.id.toast_layout_root), "你好");
			}
		});
		
	}
	
}
 

好了，一個簡單的自定義toast顯示就完成了；當然萬變不離其宗，都是類似的做法。
