Android clipboard details

Some time ago, I was busy learning things and doing things. In the past few days, my pony spent some time learning official documents. There were too many good things in it. Today I saw Clip, but I don't understand it anyway, pony made a DEMO with shameless curiosity. Let's first note that when using the Android clipboard, you only need to remember one thing, whether it's Android or PC, copy and paste can only be used on one object at a time. The general point is: on a PC, it is impossible to copy data from disk C at the same time, and copy data from disk D. For details, refer to the code, the code is very simple:
 
1. package com. xiaoma. clipboard. demo;
2.
3. import android. app. Activity;
4. import android. content. ClipData;
5. import android. content. ClipData. Item;
6. import android. content. ClipDescription;
7. import android. content. ClipboardManager;
8. import android. content. ContentResolver;
9. import android. content. Intent;
10. import android. database. Cursor;
11. import android.net. Uri;
12. import android. OS. Bundle;
13. import android. view. View;
14. import android. view. View. OnClickListener;
15. import android. widget. Button;
16. import android. widget. Toast;

The following is a temporary Activity that is used to receive values passed by Intent. The code is simpler:

There is nothing in the global configuration file, as shown below:
 
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" type = "codeph" text = "/codeph">
6.
7. <uses-sdk android: minSdkVersion = "14"/>

9. <application
10. android: icon = "@ drawable/guoguo"
11. android: label = "@ string/app_name">

If you don't understand it, you can download the DEMO written by pony directly. The code is very simple. You can skip the DEMO, and enjoy the same dishes as pony... old Rules: If the pony cannot tell me clearly, ask your friends to criticize and give advice directly. If there are any mistakes, you must correct them and make improvements together. Thank you.
