用系统的Toast提示，停留时间太短了，不满足某些应用的需求。有时候希望这个Toast能停留久一点，或者让这个Toast居中显示，所以，自己定义了一个Toast。直接上代码了：

package com.changewei.testvolleyandimageloader;import java.util.Timer;import java.util.TimerTask;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.widget.TextView;import android.widget.Toast;/** * 自定义Toast * @author chenlin * */public class ToastView {public static Toast toast;private int time;private Timer timer;/** * 构造函数，默认显示时间Toast.LENGTH_SHORT * @param context * @param text */public ToastView(Context context, String text) {LayoutInflater inflater = LayoutInflater.from(context);View view = inflater.inflate(R.layout.toast_view, null);TextView t = (TextView) view.findViewById(R.id.toast_text);t.setText(text);if(toast != null) {toast.cancel();}toast = new Toast(context);toast.setDuration(Toast.LENGTH_SHORT);toast.setView(view);}/** * 构造函数，默认显示时间Toast.LENGTH_SHORT * @param context * @param text */public ToastView(Context context, int text) {LayoutInflater inflater = LayoutInflater.from(context);View view = inflater.inflate(R.layout.toast_view, null);TextView t = (TextView) view.findViewById(R.id.toast_text);t.setText(text);if(toast != null) {toast.cancel();}toast = new Toast(context);toast.setDuration(Toast.LENGTH_SHORT);toast.setView(view);}//设置toast显示位置public void setGravity(int gravity, int xOffset, int yOffset) {//toast.setGravity(Gravity.CENTER, 0, 0); //居中显示toast.setGravity(gravity, xOffset, yOffset);}//设置toast显示时间public void setDuration(int duration) {toast.setDuration(duration);}//设置toast显示时间(自定义时间)public void setLongTime(int duration) {//toast.setDuration(duration);time = duration;timer = new Timer();        timer.schedule(new TimerTask(){        @Override        public void run() {                 if(time-1000 >= 0) {        show();        time= time - 1000;        } else {        timer.cancel();        }        }        }, 0, 1000);}public void show() {toast.show();}public static void cancel() {if(toast != null) {toast.cancel();}}}

xml文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <LinearLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:background="@drawable/toast_bg"        android:gravity="center"        android:minWidth="120dp"        android:orientation="vertical" >        <ImageView            android:layout_width="55dp"            android:layout_height="55dp"            android:layout_margin="10dp"            android:background="@drawable/ic_launcher" />        <TextView            android:id="@+id/toast_text"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_margin="8dp"            android:text=""            android:textColor="#ffffff"            android:textSize="15dp" />    </LinearLayout></LinearLayout>

toast_bg文件：

<shape xmlns:android="http://schemas.android.com/apk/res/android" >    <solid android:color="#c8333333" />    <corners        android:bottomLeftRadius="6dp"        android:bottomRightRadius="6dp"        android:topLeftRadius="6dp"        android:topRightRadius="6dp" />            </shape>

最后为这个自定义Toast的使用：

ToastView toast = new ToastView(this,"欢迎使用自定义Toast");            toast.setGravity(Gravity.CENTER, 0, 0);//设置Toast的位置            toast.setLongTime(5000);//设置Toast显示的时间            toast.show();//设置Toast显示//            toast.cancel();//取消Toast
