Android剪貼板用法詳解

更新時(shí)間：2014年10月13日 11:10:24 投稿：shichen2014

這篇文章主要介紹了Android剪貼板用法詳解,以實(shí)例的形式對(duì)Android中剪貼板的各類(lèi)傳值方法做了較為詳細(xì)的講述,需要的朋友可以參考下

本文實(shí)例詳述了Android剪貼板的用法，分享給大家供大家參考。具體方法分析如下：

這里首先需要注意的一點(diǎn)，就是在使用Android剪貼板的時(shí)候大家只記住一點(diǎn)就行了，不管是安卓設(shè)備還是PC機(jī)，復(fù)制粘貼在同一時(shí)間里只能用于一個(gè)對(duì)象上，整通俗點(diǎn)就是：PC機(jī)上，不可能同時(shí)從C盤(pán)復(fù)制，又從D盤(pán)復(fù)制就行了，具體的看代碼，很簡(jiǎn)單，直接上代碼：

復(fù)制代碼代碼如下:

下面是用來(lái)接收Intent傳遞的值，臨時(shí)的一個(gè)Activity，代碼更簡(jiǎn)單：

復(fù)制代碼代碼如下:

 package com.xiaoma.clipboard.demo;

 import android.app.Activity;

 import android.content.Intent;

 import android.os.Bundle;

 import android.view.TextureView;

 import android.widget.TextView;

 /**

  * @Title: ReceiverClip.java

  * @Package com.xiaoma.clipboard.demo

  * @Description:臨時(shí)用來(lái)接收下從Clip傳過(guò)來(lái)的Intent值

  * @author MZH

  */

 public class ReceiverClip extends Activity {

     private TextView tv1 ; 

     private TextView tv2 ;

     @Override

     protected void onCreate(Bundle savedInstanceState) {

         // TODO Auto-generated method stub

         super.onCreate(savedInstanceState);

         setContentView(R.layout.main2);

         init();

     }

     private void init(){

         tv1 = (TextView)findViewById(R.id.xiaoma);

         tv2 = (TextView)findViewById(R.id.yatou);

         Intent intent = getIntent();

         Bundle b =intent.getBundleExtra("XiaoMaGuo");

         if(b != null){

             int xiaoma = b.getInt("xiaoma");

             int yatou = b.getInt("yatou");

             if(!"".equals(String.valueOf(xiaoma)) && !"".equals(String.valueOf(yatou))){

                 tv1.setText(String.valueOf(xiaoma));

                 tv2.setText(String.valueOf(yatou));

             }

         }

     }

 }

全局配置文件里面沒(méi)什么，如下：

復(fù)制代碼代碼如下:

 <?xml version="1.0" encoding="utf-8"?>

 <manifest xmlns:android=""

     package="com.xiaoma.clipboard.demo"

     android:versionCode="1"

     android:versionName="1.0" >
