Android 获取手机联系人和手机短信和一个简单的yinyue

1.读取手机联系人

//获取内容访问者
ContentResolver cr = getContentResolver();

mLvShow = (ListView) findViewById(R.id.lv_show);
dataList = getDataList();
adapter = new SimpleAdapter(this, dataList, R.layout.simple_contacts_item//
, new String[] { "name", "number", "email" }//
, new int[] { R.id.tv_name, R.id.tv_number, R.id.tv_email });
mLvShow.setAdapter(adapter);
}

/**
* 加载数据
*
* @return
*/
private List<Map<String, String>> getDataList() {
List<Map<String, String>> list = new ArrayList<Map<String, String>>();
ContentResolver resolver = getContentResolver();
Cursor cursor = resolver.query(ContactsContract.RawContacts.CONTENT_URI,
new String[] { ContactsContract.RawContacts._ID, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY }//
, null, null, null);
while (cursor.moveToNext()) {
Map<String, String> map = new HashMap<String, String>();
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts._ID));// "_id"
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY));// "display_name"
map.put("name", name);

// 联系人号码
Cursor phoneCursor = resolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI//
, new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER }// "data1"
, "raw_contact_id=?", new String[] { id }, null);
if (phoneCursor.moveToNext()) {
String number = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
map.put("number", number);
}

// 联系人邮箱
Cursor emailCursor = resolver.query(ContactsContract.CommonDataKinds.Email.CONTENT_URI//
, new String[] { ContactsContract.CommonDataKinds.Email.ADDRESS}// "data1"
, "raw_contact_id=?", new String[] { id }, null);
if (emailCursor.moveToNext()) {
String email = emailCursor.getString(emailCursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.ADDRESS));
map.put("email", email);
}
list.add(map);
}
return list;
}
}

在用ListView展示出来

2.获取手机短信内容

根据内容提供者来获取

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_massage);
listview = (ListView) this.findViewById(R.id.listView_main_smslist);
empty = (TextView) this.findViewById(R.id.text_main_empty);
listview.setEmptyView(empty);
// 内容提供者获取数据库操作链接和数据库内的数据
// 通过Context类获取ContentResolver
resolver = getContentResolver();

cursor = resolver.query(Uri.parse(uri), new [/b]String[] { "_id",
"address", "body", "date", "type" }, null, null, null);
smsList = cursorToList(cursor);
// 建一个baseAdapter类
adapter = new MybaseAdapter(smsList);
listview.setAdapter(adapter);

}

public List<Map<String, String>> cursorToList(Cursor cursor2) {
List<Map<String, String>> list = new ArrayList<Map<String, String>>();
while (cursor2.moveToNext()) {// 注意：这里是循环每一行的数据
Map<String, String> smsItem = new HashMap<String, String>();
for (int i = 0; i < cursor2.getColumnCount(); i++) {// 这里是循环每一行的列数
smsItem.put(cursor2.getColumnName(i), cursor2.getString(i));// 键：key:存储每一行的字段，value:值就是内容
}
list.add(smsItem);
}
cursor2.close();
return list;
}

class MybaseAdapter extends BaseAdapter {
private List<Map<String, String>> smsList;

public MybaseAdapter(List<Map<String, String>> smsList) {
this.smsList = smsList;
}

@Override
public int getCount() {
return this.smsList.size();
}

@Override
public Object getItem(int position) {
return this.smsList.get(position);
}

@Override
public long getItemId(int position) {
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
if (convertView == null) {
holder = new ViewHolder();
convertView = getLayoutInflater().inflate(
R.layout.item_listview, null);
TextView text_address = (TextView) convertView
.findViewById(R.id.text_item_address);
TextView text_body = (TextView) convertView
.findViewById(R.id.text_item_body);
TextView text_date = (TextView) convertView
.findViewById(R.id.text_item_date);
ImageView image_type = (ImageView) convertView
.findViewById(R.id.imageView_item_icon);

holder.text_address = text_address;
holder.text_body = text_body;
holder.text_date = text_date;
holder.image_type = image_type;
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// 设置UI控件的内容
holder.text_address.setText(this.smsList.get(position).get(
"address"));
holder.text_body.setText(this.smsList.get(position).get("body"));
long mills = Long.parseLong(this.smsList.get(position).get("date")
.toString());
SimpleDateFormat adf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
holder.text_date.setText(adf.format(new Date(mills)));
int type = Integer.parseInt(this.smsList.get(position).get("type")
.toString());
switch (type) {
case 1:
holder.image_type.setImageResource(R.drawable.file);

break;
case 2:
holder.image_type.setImageResource(R.drawable.folder);
break;
}
return convertView;
}

class ViewHolder {
private TextView text_address;
private TextView text_body;
private TextView text_date;
private ImageView image_type;
}
}

在清单文件加上权限

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

3.一个简单的音乐播放

主要是MediaPlayer

代码如下

public class MainActivity extends AppCompatActivity {

private MediaPlayer mediaPlayer;
private SeekBar sb_main_bar;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sb_main_bar = (SeekBar) findViewById(R.id.sb_main_bar);
sb_main_bar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {

}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {
int progress=seekBar.getProgress();
//在当前位置播放
mediaPlayer.seekTo(progress);
}
});

}
public void isPlayOrPause(View view){

ImageButton imageButton= (ImageButton) view;
if (mediaPlayer==null){
mediaPlayer = MediaPlayer.create(this, R.raw.f);
mediaPlayer.start();
imageButton.setImageResource(android.R.drawable.ic_media_pause);
}else if (mediaPlayer.isPlaying()){
mediaPlayer.pause();
imageButton.setImageResource(android.R.drawable.ic_media_play);
}else{
mediaPlayer.start();
imageButton.setImageResource(android.R.drawable.ic_media_pause);
}

}
class  MyThread extends Thread{
@Override
public void run() {
super.run();
while(sb_main_bar.getProgress()<=sb_main_bar.getMax()){
//获取音乐当前播放的位置
int position=mediaPlayer.getCurrentPosition();
sb_main_bar.setProgress(position);
}
}
}
}
