Android获取手机联系人电话号码并返回结果

之前做了一个小练习需要用到获取手机里联系人的电话号码，通过查阅相关的资料，自己尝试写了一个小例子，可以成功获取。
首先需要在AndroidManifest.xml中获取权限

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

xml布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical" >
  <TextView 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="电话号码是："/>
  <EditText 
    android:id="@+id/editNumber"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:editable="false"/>
  <Button 
    android:id="@+id/buttonQuary"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="查询联系人"/>
</LinearLayout>

MainActivity.java

package com.getcontacts;
import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
  Button button;
  EditText editText;
  private Uri uri_DATA = Uri.parse("content://com.android.contacts/data");
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    button = (Button) findViewById(R.id.buttonQuary);
    editText = (EditText) findViewById(R.id.editNumber);
    button.setOnClickListener(new OnClickListener() {
      @Override
      public void onClick(View arg0) {
        // TODO Auto-generated method stub
        editText.setText("");  //做跳转之前先把电话号码清空
        Intent intent = new Intent(Intent.ACTION_PICK,
            android.provider.ContactsContract.Contacts.CONTENT_URI);
        startActivityForResult(intent, 1);
      }
    });
  }
  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == 1) { //请求码为1
      Log.i("info","resultADD");
      String strNumber = "";
      if(data != null) { //判断返回的intent是不是为空
        Uri uri = data.getData();
        Log.i("info", uri.toString()); //在log打印出来获取的uri
        Cursor cursor = getContentResolver().query(uri, null, null, null, null);
        while(cursor.moveToNext()) {
          String strID = cursor.getString(cursor.getColumnIndex("name_raw_contact_id"));
          Cursor cursor2 = getContentResolver().query(uri_DATA, null,
              "raw_contact_id = " + strID + " and mimetype_id = 5", null, null);
          if(cursor2.moveToFirst()) {
            strNumber = cursor2.getString(cursor2.getColumnIndex("data1"));
            strNumber = strNumber.replace(" ", "");
            strNumber = strNumber.replace("-", "");
          }
          cursor2.close();
        }
        cursor.close();
        editText.setText(strNumber);
      }
    }
  }
}
