My style, blah blah blah, directly to everyone posted the code.
The specific code is as follows:
package com.org.demo.demo;
import com.org.wangfeng.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class GetPhoneActivity extends Activity {
private EditText editText;
private Button button;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.getphoneactivity);
editText = (EditText) findViewById(R.id.et_getphone);
button = (Button) findViewById(R.id.bb_getphone);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(GetPhoneActivity.this,
ContactActivity.class);
startActivityForResult(intent, 1);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// System.out.println("resultCode:" + resultCode);
// System.out.println("requestCode:" + requestCode);
Log.d("jiejie", " Is called the ");
if (resultCode == Activity.RESULT_OK) {
String phone = data.getStringExtra("phone");
Log.d("jiejie", "_______________"+phone);
phone = phone.replaceAll("-", "").replaceAll(" ", "");// replace - And Spaces
editText.setText(phone);// Set the phone number to the input field
}
super.onActivityResult(requestCode, resultCode, data);
}
}
package com.org.demo.demo;
import java.util.ArrayList;
import java.util.HashMap;
import com.org.wangfeng.R;
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.TextView;
public class ContactActivity extends Activity {
private ListView lvList;
private ArrayList<HashMap<String, String>> readContact;
private TextView back;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contact);
back =(TextView)findViewById(R.id.back);
back.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
finish();
}
});
lvList = (ListView) findViewById(R.id.lv_list);
readContact = readContact();
// System.out.println(readContact);
lvList.setAdapter(new SimpleAdapter(this, readContact,
R.layout.contact_list_item, new String[] { "name", "phone" },
new int[] { R.id.tv_name, R.id.tv_phone }));
lvList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String phone = readContact.get(position).get("phone");// Read the current item Telephone number of
Intent intent = new Intent();
intent.putExtra("phone", phone);
setResult(Activity.RESULT_OK, intent);// Put the data in intent Go back to 1 A page
finish();
}
});
}
private ArrayList<HashMap<String, String>> readContact() {
// First of all, , from raw_contacts To read a contact in id("contact_id")
// The second , According to the contact_id from data The corresponding phone number and contact name are retrieved from the table
// then , According to the mimetype To distinguish which one is the contact , Which is the phone number
Uri rawContactsUri = Uri
.parse("content://com.android.contacts/raw_contacts");
Uri dataUri = Uri.parse("content://com.android.contacts/data");
ArrayList<HashMap<String, String>> list = new ArrayList<HashMap<String, String>>();
// from raw_contacts To read a contact in id("contact_id")
Cursor rawContactsCursor = getContentResolver().query(rawContactsUri,
new String[] { "contact_id" }, null, null, null);
if (rawContactsCursor != null) {
while (rawContactsCursor.moveToNext()) {
String contactId = rawContactsCursor.getString(0);
// System.out.println(contactId);
// According to the contact_id from data The corresponding phone number and contact name are retrieved from the table , You're actually querying the view view_data
Cursor dataCursor = getContentResolver().query(dataUri,
new String[] { "data1", "mimetype" }, "contact_id=?",
new String[] { contactId }, null);
if (dataCursor != null) {
HashMap<String, String> map = new HashMap<String, String>();
while (dataCursor.moveToNext()) {
String data1 = dataCursor.getString(0);
String mimetype = dataCursor.getString(1);
// System.out.println(contactId + ";" + data1 + ";"
// + mimetype);
if ("vnd.android.cursor.item/phone_v2".equals(mimetype)) {
map.put("phone", data1);
} else if ("vnd.android.cursor.item/name"
.equals(mimetype)) {
map.put("name", data1);
}
}
list.add(map);
dataCursor.close();
}
}
rawContactsCursor.close();
}
return list;
}
}
This is the end of the code, the code is relatively simple, with comments, hope to learn android to get mobile contacts related knowledge to help you.
