Enter Chinese Characters in Android to get pinyin

Some time ago, I studied the android address book and found it in its contacts2.db database.Raw_contactsThe sort_key column in the table is used for sorting of Chinese pinyin and other information. It suddenly comes to mind that we can use it to get the corresponding Chinese pinyin.

 

Sorry, my simulator cannot input Chinese characters. If it is a Chinese name named "Zhang San", it should be stored in the form of "Zhang zhangsan III"

My specific ideas are as follows:

1. Insert Chinese characters into the table

2. Look up the table and find this field. After corresponding processing, the output

3. Delete this field

 

There are many tables in contacts2.db. For more information, please download the project at the end of this article, which contains the project in this article. Check the small software of the contacts2.db database and relevant tutorials! (PS: To export contacts2.db, the simulator must be enabled first)

 

In this case, you need to perform read and write operations on the address book, so add the corresponding permissions to androidmanifest. xml:

<uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.WRITE_CONTACTS" /> 

 

Paste the Code:

Package COM. pinyin; import android. app. activity; import android. content. contenturis; import android. content. contentvalues; import android. database. cursor; import android.net. uri; import android. OS. bundle; import android. provider. contactscontract; import android. provider. contactscontract. commondatakinds. structuredname; import android. provider. contactscontract. data; import android. provider. contactscontract. raw Contacts; import android. view. view; import android. widget. button; import android. widget. edittext; import android. widget. imagebutton; import android. widget. textview; import android. widget. toast; public class pinyinactivity extends activity {/** called when the activity is first created. */edittext et; button Bt; textview TV; @ override public void oncreate (bundle savedinstancestate) {super. oncreate (save Dinstancestate); setcontentview (R. layout. main); bt = (button) findviewbyid (R. id.

Input the Chinese character to the pinyin project and the contacts2.dbsoftware. Tutorial. Zip
