痛定思痛。 2022-09-20 15:03 226阅读 0赞

一样，因为这是对通讯录进行操作，因此我们需要添加相应的权限。

<uses-permission android:name="android.permission.READ\_CONTACTS"/>  
<uses-permission android:name="android.permission.WRITE\_CONTACTS"/>

代码如下所示:

package com.itfom.contentprovider;
    
    import android.app.Activity;
    import android.content.ContentResolver;
    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.Email;
    import android.provider.ContactsContract.CommonDataKinds.Phone;
    import android.provider.ContactsContract.CommonDataKinds.StructuredName;
    import android.provider.ContactsContract.Data;
    import android.provider.ContactsContract.RawContacts;
    import android.util.Log;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    
    public class MainActivity extends Activity {
    	private static final String TAG = "ContactTest";
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    		//实例化控件并绑定监听事件
    		Button btn_get=(Button) findViewById(R.id.btn_get);
    		Button btn_add=(Button) findViewById(R.id.btn_add);
    		//设置监听事件
    		//添加联系人
    		btn_add.setOnClickListener(new OnClickListener() {
    
    			@Override
    			public void onClick(View v) {
    				ContentValues values = new ContentValues();
    				//首先向RawContacts.CONTENT_URI执行一个空值插入，目的是获取系统返回的rawContactId
    				Uri rawContactUri = MainActivity.this.getContentResolver().insert(RawContacts.CONTENT_URI, values);
    				long rawContactId = ContentUris.parseId(rawContactUri);
    
    				//往data表入姓名数据
    				values.clear();
    				values.put(Data.RAW_CONTACT_ID, rawContactId);
    				values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
    				values.put(StructuredName.GIVEN_NAME, "zhangsan");
    				MainActivity.this.getContentResolver().insert(

    				values.put(Phone.TYPE, Phone.TYPE_MOBILE);

    				values.put(Data.MIMETYPE, Email.CONTENT_ITEM_TYPE);
    				values.put(Email.DATA, "xsc218@126.com");
    				values.put(Email.TYPE, Email.TYPE_WORK);
    				MainActivity.this.getContentResolver().insert(
    						android.provider.ContactsContract.Data.CONTENT_URI, values);
    			}
    		});
    		//获取联系人

    				Cursor cursor = contentResolver.query(uri, null, null, null, null);
    				while(cursor.moveToNext()){
    					// 获取联系人姓名
    					StringBuilder sb = new StringBuilder();

    					String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
    					sb.append("contactId=").append(contactId).append(",name=").append(name);
    
    					//获取联系人手机号码
