android应用开发之屡次触发toast的处理

【场景】：当一个比如listview多次点击toast,这时候会出现toast延迟的情况

【处理】：以最后一次toast为准处理

【使用方法】：

private ToastUtils mToastUtils;mToastUtils.toast("toast");  //默认的持续的时间是0mToastUtils.toast("toast",1);//可以自定义toast的持续时间

【实现如下】：

ToastUtils.java

import android.content.Context;import android.view.Gravity;import android.view.LayoutInflater;import android.view.View;import android.widget.TextView;import android.widget.Toast;public class ToastUtils {	public ToastUtils(Context context) {		ToastMsg.BUILDER.init(context);	}	public enum ToastMsg {		BUILDER;		private Toast toast;		private TextView tv;		private View view;		private void init(Context context) {			view = LayoutInflater.from(context).inflate(R.layout.toast, null);			tv = (TextView) view.findViewById(R.id.tv_toast);			toast = new Toast(context);			toast.setView(view);		}		public void showToast(CharSequence text, int duration) {			if (text.length() != 0) {				tv.setText(text);				toast.setDuration(duration);				toast.setGravity(Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0,						40);				toast.show();			}		}		public void showToast(int id, int duration) {			if (id != 0) {				tv.setText(id);				toast.setDuration(duration);				toast.setGravity(Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0,						40);				toast.show();			}		}	}	public void toast(String text) {		ToastMsg.BUILDER.showToast(text, 0);	}	public void toast(String text, int duration) {		ToastMsg.BUILDER.showToast(text, duration);	}	public void toast(int id) {		ToastMsg.BUILDER.showToast(id, 0);	}}
