Android uses the Clipboard to pass data

Reprinted from Android Clipboard detailed http://www.2cto.com/kf/201203/123455.html

Some time ago busy learning things to do things, these days pony have time to take to learn the official documents, inside good things too much, today saw clip, anyway do not understand, pony with shameless curiosity, did a demo, first to note the point of attention, is in the use of Android clipboard when everyone just remember a little, whether it is Android device or PC, copy and paste at the same time can only be used for an object, the whole popular point is: PC, it is impossible to copy from the C disk at the same time, from the D disk copy on the line, the specific look at the code, very simple, Directly on the code:

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;
. import Android.database.Cursor;
One. Import Android.net.Uri;
Import Android.os.Bundle;
Import Android.view.View;
Import Android.view.View.OnClickListener;

Here is the value to receive the intent pass, a temporary activity, the code is simpler:

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

1. <?xml version= "1.0" encoding= "Utf-8"?>
2. <manifest xmlns:android= ""

4. android:versioncode= "1"

If you do not see the bad, friends can directly download the pony to write the demo, the code is very simple, Daniel skipped, and pony-like vegetables can learn to exchange, roar ... The usual, such as the small horse is not clear where, but also ask a friend direct criticism, mistakes will change, together improve progress, thank you
