本文介绍了一种在Android应用中异步查询通讯录的方法，并提供了详细的代码实现。通过使用AsyncQueryHandler，文章展示了如何获取联系人姓名及电话号码等信息。

准备做个通话录音的东西，下面是异步查询通讯录的代码

	private static final String TAG = "ContractChoseActivity";
	
	private int sdkVersion = 4;
	private String mColumnName = null;

	
	private ListView mListView;
	
	private MyAdapter mAdapter;
	private ListQueryHandler mQueryHandler;
	
	public void onCreate(Bundle bundle){
		super.onCreate(bundle);
		
		setContentView(R.layout.contract);
		mListView = (ListView) this.findViewById(R.id.contract_list);
		
		mQueryHandler = new ListQueryHandler(getContentResolver());
		queryList(mQueryHandler);
	}
	
	
	private void queryList(AsyncQueryHandler async) {
		if (async != null) {
			
			try {
				sdkVersion = Integer.parseInt(android.os.Build.VERSION.SDK.trim());
			} catch (Exception e) {
				sdkVersion = 3;
			}
			
            Uri personUri = null;
            if(sdkVersion > 4){//2.x，sdk版本
                personUri = Uri.parse("content://com.android.contacts/contacts");
                mColumnName = "display_name";
            }else{//1.6以下SDK
                personUri = Contacts.People.CONTENT_URI;
                mColumnName = Contacts.People.NAME;
            }
            //开始异步查询
			async.startQuery(0, null, personUri, null, null, null, null);
		}
	}
	
	
	class MyAdapter extends CursorAdapter {

		private LayoutInflater mInflater;

		public MyAdapter(Context context, Cursor c) {
			super(context, c);
			mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		}

		public int getListLength() {
			int ret = 0;
			if (getCursor() != null)
				ret = getCount();
			return ret;

		}

		
		@Override
		public void bindView(View view, Context context, Cursor cursor) {
			ItemStruct struct = (ItemStruct) view.getTag();
			
			if(cursor != null){
				try{
					struct.name.setText(cursor.getString(cursor.getColumnIndex(mColumnName)));
//					struct.number.setText(cursor.getString((cursor.getColumnIndex(Contacts.People.NUMBER))));
				}catch(Exception ex){
					Log.d(TAG, "exception>>"+ex.toString());
					ex.printStackTrace();
				}

			}
		}

		@Override
		public View newView(Context context, Cursor cursor, ViewGroup parent) {
			View convertView = null;
			convertView = mInflater.inflate(R.layout.contract_row, parent, false);
			ItemStruct struct = new ItemStruct();
			struct.checkbox = (CheckBox) convertView.findViewById(R.id.contract_checkbox);
			struct.name = (TextView) convertView.findViewById(R.id.contract_name);
			struct.number = (TextView) convertView.findViewById(R.id.contract_number);
			convertView.setTag(struct);
			return convertView;
		}

		private class ItemStruct {
			CheckBox checkbox;
			TextView name;
			TextView number;
		}

	}
	
	class ListQueryHandler extends AsyncQueryHandler {

		public ListQueryHandler(ContentResolver cr) {
			super(cr);
		}

		/**
		 * 异步查询结束时
		 */
		public void onQueryComplete(int token, Object cookie, Cursor cursor) {

			if (cursor != null) {
				
				if (mAdapter == null) {
					mAdapter = new MyAdapter(ContractChoseActivity.this, cursor);
					mListView.setAdapter(mAdapter);
				} else {
					mAdapter.changeCursor(cursor);

				}
			}

		}

本来打算连电话号码一起显示的，后来发现不在同一张表中，google的通讯录不是简单的电话本，这张表中只有个字段是has_phone_number，然后可以还需要继续跟进id去匹配查询另外一张表才可以得到全部的电话号码（1个人可以有多个号码）。下面的代码具体有方式：
