前段時間忙著學東西做東西，這幾天小馬有時間就拿來學習下官方的文檔，裡面好東西太多瞭，今天看到瞭Clip，反正不懂，小馬帶著無恥的好奇心，做瞭個DEMO，先講下註意的一點，就是在使用Android剪貼板的時候大傢隻記住一點就行瞭，不管是安卓設備還是PC機，復制粘貼在同一時間裡隻能用於一個對象上，整通俗點就是：PC機上，不可能同時從C盤復制，又從D盤復制就行瞭，具體的看代碼，很簡單，直接上代碼：

下面是用來接收Intent傳遞的值，臨時的一個Activity，代碼更簡單：
1. package com.xiaoma.clipboard.demo;
2.
3. import android.app.Activity;
4. import android.content.Intent;
5. import android.os.Bundle;
6. import android.view.TextureView;
7. import android.widget.TextView;
8.
9. /**
10. * @Title: ReceiverClip.java
11. * @Package com.xiaoma.clipboard.demo
12. * @Description:臨時用來接收下從Clip傳過來的Intent值
13. * @author MZH
14. */
15. public class ReceiverClip extends Activity {
16.
17. private TextView tv1 ;
18. private TextView tv2 ;
19.
20. @Override
21. protected void onCreate(Bundle savedInstanceState) {
22. // TODO Auto-generated method stub
23. super.onCreate(savedInstanceState);
24. setContentView(R.layout.main2);
25. init();
26. }
27.
28. private void init(){
29.
30. tv1 = (TextView)findViewById(R.id.xiaoma);
31. tv2 = (TextView)findViewById(R.id.yatou);
32.
33. Intent intent = getIntent();
34. Bundle b =intent.getBundleExtra("XiaoMaGuo");
35. if(b != null){
36. int xiaoma = b.getInt("xiaoma");
37. int yatou = b.getInt("yatou");
38. if(!"".equals(String.valueOf(xiaoma)) && !"".equals(String.valueOf(yatou))){
39. tv1.setText(String.valueOf(xiaoma));
40. tv2.setText(String.valueOf(yatou));
41. }
42. }
43. }
44. }
全局配置文件裡面沒什麼，如下：
1. <?xml version="1.0" encoding="utf-8"?>
2. <manifest xmlns:android=""
3. package="com.xiaoma.clipboard.demo"
4. android:versionCode="1"
5. android:versionName="1.0" >
6.
7. <uses-sdk android:minSdkVersion="14" />
8.
9. <application
10. android:icon="@drawable/guoguo"
11. android:label="@string/app_name" >
12. <activity
13. android:name=".ClipBoardDemoActivity"
14. android:label="@string/app_name" >
15. <intent-filter>
16. <action android:name="android.intent.action.MAIN" />
17.
18. <category android:name="android.intent.category.LAUNCHER" />
19. </intent-filter>
20. </activity>
21. <activity android:name=".ReceiverClip"></activity>
22. </application>
23.
24. </manifest>
如果因為沒效果圖看不爽的話，朋友們可以直接下載小馬寫的DEMO，代碼很簡單，大牛跳過,跟小馬一樣的菜菜可以學習交流下，吼吼…老規矩，如有小馬講不清楚的地方，還請朋友直接批評指點，有錯必改，共同提高進步,謝謝
