curosr 查询之查询本地电话

package com.example.sdsds;

import android.app.Activity;

import android.content.ContentResolver;

import android.database.Cursor;

import android.os.Bundle;

import android.provider.CallLog;

import android.support.v4.widget.SimpleCursorAdapter;

import android.util.Log;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.TextView;

public class MainActivity extends Activity {

     private SimpleCursorAdapter adapter = null;

    @Override

    protected void onCreate(Bundle savedInstanceState) {        

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

//得到管理容器

        ContentResolver resolver = getContentResolver(); 

通过手机号查询到最近的通话记录

        Cursor cursor = resolver.query(CallLog.Calls.CONTENT_URI, null, "number=?", new String[]{"10086"}, null);

将光标移动到最后一位

        cursor.moveToLast();

显示数值

        String value = cursor.getString(cursor.getColumnIndex("duration"));

        Log.d("dsds", value);

    }

        //cursor.getString((1));
