2024-01-26 06:50:03 66

利用AsyncQueryHandler能异步任务获取手机联系人，增加用户体验，使用起来也很方便。不多说，上干货。

布局文件main.xml

contact.java联系人bean文件

packagecom.larson.cantact;
publicclassContact{
privateintcontactId;//联系人ID
privateStringdisplayName;//联系人姓名
privateStringphoneNum;//联系人手机号
privateStringsortKey;//排序Key
privateLongphotoId;//头像ID
privateStringlookUpKey;
privateintselected=0;//被选中的行号
privateStringformattedNumber;//被格式化的号码
privateStringpinyin;//姓名对应的汉语拼音

publicintgetContactId(){
returncontactId;
}
publicvoidsetContactId(intcontactId){
this.contactId=contactId;
}
publicStringgetDisplayName(){
returndisplayName;
}
publicvoidsetDisplayName(StringdisplayName){
this.displayName=displayName;
}
publicStringgetPhoneNum(){
returnphoneNum;
}
publicvoidsetPhoneNum(StringphoneNum){
this.phoneNum=phoneNum;
}
publicStringgetSortKey(){
returnsortKey;
}
publicvoidsetSortKey(StringsortKey){
this.sortKey=sortKey;
}
publicLonggetPhotoId(){
returnphotoId;
}
publicvoidsetPhotoId(LongphotoId){
this.photoId=photoId;
}
publicStringgetLookUpKey(){
returnlookUpKey;
}
publicvoidsetLookUpKey(StringlookUpKey){
this.lookUpKey=lookUpKey;
}
publicintgetSelected(){
returnselected;
}
publicvoidsetSelected(intselected){
this.selected=selected;
}
publicStringgetFormattedNumber(){
returnformattedNumber;
}
publicvoidsetFormattedNumber(StringformattedNumber){
this.formattedNumber=formattedNumber;
}
publicStringgetPinyin(){
returnpinyin;
}
publicvoidsetPinyin(Stringpinyin){
this.pinyin=pinyin;
}
}

MainActivity.java

packagecom.larson.cantact;
importjava.util.ArrayList;
importandroid.app.Activity;
importandroid.content.AsyncQueryHandler;
importandroid.content.ContentResolver;
importandroid.database.Cursor;
importandroid.net.Uri;
importandroid.os.Bundle;
importandroid.os.Handler;
importandroid.os.Message;
importandroid.provider.ContactsContract;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.widget.Button;
publicclassMainActivityextendsActivity{

privateAsyncQueryHandlerasyncQuery;
@Override
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myCantacts=(Button)this.findViewById(R.id.bt_getCantacts);
myCantacts.setOnClickListener(newOnClickListener(){
@Override
publicvoidonClick(Viewv){
asyncQuery=newMyAsyncQueryHandler(getContentResolver());
initSQL();
}
});
}
protectedvoidinitSQL(){
//联系人URI
Uriuri=ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
//联系人ID，联系人NAME,
String[]projection={ContactsContract.CommonDataKinds.Phone._ID,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.DATA1,"sort_key",
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,};
asyncQuery.startQuery(0,null,uri,projection,null,null,
"sort_keyCOLLATELOCALIZEDasc");
}
privateclassMyAsyncQueryHandlerextendsAsyncQueryHandler{
publicMyAsyncQueryHandler(ContentResolvercr){
super(cr);
}
protectedvoidonQueryComplete(inttoken,Objectcookie,Cursorcursor){
querying(cursor);
}
}
privatevoidquerying(finalCursorcursor){
HandlerhandlerInsertOrder=newHandler(){
publicvoidhandleMessage(Messagemsg){
switch(msg.what){
caseMyAsyncTask.DOWNLOADING_START_MESSAGE:
System.out.println("begintosortoutt9");
break;
caseMyAsyncTask.DOWNLOAD_END_MESSAGE:
Bundlebundle1=msg.getData();
ArrayListlist=(ArrayList)bundle1
.get("完成");
for(ContactBeanci:list){
System.out.println(ci.getDisplayName());
System.out.println(ci.getPhoneNum());
System.out.println("--------------------------------");
}
break;
default:
break;
}
super.handleMessage(msg);
}
};
MyAsyncTask.startRequestServerData(this,handlerInsertOrder,cursor);
}
}

自定义的MyAsyncTask.java

packagecom.anjoyo.cantact;
importjava.util.ArrayList;
importandroid.content.Context;
importandroid.database.Cursor;
importandroid.os.AsyncTask;
importandroid.os.Bundle;
importandroid.os.Handler;
importandroid.os.Message;
publicclassMyAsyncTaskextends
AsyncTask>{
/**开始整理*/
publicstaticfinalintDOWNLOADING_START_MESSAGE=7;
/**整理结束*/
publicstaticfinalintDOWNLOAD_END_MESSAGE=17;
privateContextmContext=null;
privateHandlermHandler=null;
protectedMyAsyncTask(Contextcontext,Handlerhandler){
this.mContext=context;
this.mHandler=handler;
}
@Override
protectedvoidonPreExecute(){
sendStartMessage(DOWNLOADING_START_MESSAGE);
}
@Override
protectedArrayListdoInCursor...params){
//只需要把原来放在子线程的代码放到这个方法就行
Cursorcursor=params[0];
ArrayListciList=newArrayList();
if(cursor!=null&&cursor.getCount()>0){
try{
cursor.moveToFirst();
for(inti=0;iresult){
sendEndMessage(DOWNLOAD_END_MESSAGE,result);
}
publicstaticvoidstartRequestServerData(Contextcontext,Handlerhandler,
Cursorcursor){
newMyAsyncTask(context,handler).execute(cursor);
}
/**
*发送开始整理消息
*
*@parammessageWhat
*/
privatevoidsendStartMessage(intmessageWhat){
Messagemessage=newMessage();
message.what=messageWhat;
if(mHandler!=null){
mHandler.sendMessage(message);
}
}
/**
*发送整理结束消息
*
*@parammessageWhat
*/
privatevoidsendEndMessage(intmessageWhat,ArrayListresult){
Messagemessage=newMessage();
message.what=messageWhat;
Bundlebundle=newBundle();
bundle.putSerializable("完成",result);
message.setData(bundle);
if(mHandler!=null){
mHandler.sendMessage(message);
}
}
}
