First 1 point to note here, that is, when using Android clipboard everybody just remember 1 point, whether android devices or PC machine, copy and paste in the same time can only be used for 1 one object, the popular point is: PC machine, cannot simultaneously from C disk replication, and from D disk replication, specific look at the code, very simple, directly on the code:

package com.xiaoma.clipboard.demo;
 
 import android.app.Activity;

             ContentResolver cr = getContentResolver();
             ClipData cdUri = clipboard.getPrimaryClip();

                         if (pasteCursor != null) {
                             if (pasteCursor.moveToFirst()) {
                                  // This is where you can manipulate the data , The premise is that you have permissions
                             }
                         }
                         pasteCursor.close();
                      }
                  }
             }
         }
     }
 }

The following is the value used to receive the Intent pass, temporary 1 Activity, the code is simpler:

 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: Used temporarily to receive the lower slave Clip To get the Intent value
  * @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));
             }
         }
     }
 }

There is nothing in the global configuration file, as follows:

 <?xml version="1.0" encoding="utf-8"?>
 <manifest xmlns:android=""
     package="com.xiaoma.clipboard.demo"
     android:versionCode="1"
     android:versionName="1.0" >
 
     <uses-sdk android:minSdkVersion="14" />
 
     <application
         android:icon="@drawable/guoguo"
         android:label="@string/app_name" >
         <activity
             android:name=".ClipBoardDemoActivity"
             android:label="@string/app_name" >
             <intent-filter>
                 <action android:name="android.intent.action.MAIN" />
 
                 <category android:name="android.intent.category.LAUNCHER" />
             </intent-filter>
         </activity>
         <activity android:name=".ReceiverClip"></activity>
     </application>
 
 </manifest>
