自定义toast外形,多次点击不会总是弹出toast的实现方法

package com.amt.appstore.widgets;

import com.amt.appstore.R;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

public class CustomerToast {

 static Toast toast;

 public static void showToast(Context context, String content) {

 LayoutInflater inflater = LayoutInflater.from(context);
 View view = inflater.inflate(R.layout.toast_custome, null);
 TextView tv = (TextView) view.findViewById(R.id.text);
 tv.setText(content);

 //防止多次点击按钮出现很多toast一直不消失
 if (toast != null) {
  toast.setView(view);
 } else {
  toast = new Toast(context);
  toast.setView(view);
  toast.setDuration(Toast.LENGTH_SHORT);
 }
 toast.show();
 }

}

toast_custome里的代码如下所示：

<&＃63;xml version="1.0" encoding="utf-8"&＃63;>
