Activity which shows the name and number in list view... 在列表视图中显示姓名和号码的活动...
public class FirstActivity extends Activity {
ListView list;
ArrayList<HashMap<String, String>> al = new ArrayList<HashMap<String,String>>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
list = (ListView) findViewById(R.id.list);
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
while(phones.moveToNext())
{
HashMap<String, String> nameNumberMap = new HashMap<String, String>();
String contactName = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String contactNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
nameNumberMap.put("Name",contactName);
nameNumberMap.put("Number",contactNumber);
al.add(nameNumberMap);
}
Log.e("check","as2");
customAdapter adapter = new customAdapter(this, al);
list.setAdapter(adapter);
Log.e("check","as2"+al.size());
}
}
Custom Adapter class 自定义适配器类
public class customAdapter extends BaseAdapter {
ArrayList<HashMap<String, String>> al = new ArrayList<HashMap<String,String>>();
Activity activity;
private static LayoutInflater inflater = null;
public customAdapter(Activity a, ArrayList<HashMap<String, String>> al) {
Log.e("check", "");
activity = a;
this.al = al;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return al.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi=convertView;
if(convertView==null)
{
vi = inflater.inflate(R.layout.row_layout, null);
}
TextView name = (TextView) vi.findViewById(R.id.Name);
TextView number = (TextView) vi.findViewById(R.id.Number);
HashMap<String, String> contains = new HashMap<String, String>();
contains = al.get(position);
Log.e("value check:----", contains.get("Name"));
name.setText(contains.get("Name"));
number.setText(contains.get("Number"));
return vi;
}
}
XML for first activity 首次活动的XML
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
XML for row layout 行布局的XML

Edit 编辑
This code is for the search functionality of the contacts 此代码用于联系人的搜索功能
what I do here is when user goes on typing in the edit text the name contacts are searched from the contacts list and are displayed in the listview below edittext...this is similar to our default contacts search functionality in contacts list or phonebook of our device 我在这里所做的是，当用户继续输入编辑文本时，将从联系人列表中搜索联系人姓名并显示在edittext下面的列表视图中……这类似于我们的联系人列表或电话簿中的默认联系人搜索功能设备
EditText edit_text=(EditText)findViewById(R.id.txtItem);
edit_text.addTextChangedListener(new TextWatcher() {
@Override
public void afterTextChanged(Editable changed_text) {
// TODO Auto-generated method stub
//String search_value=getText(R.id.txtItem).toString();
//Toast.makeText(getApplicationContext(), changed_text,Toast.LENGTH_SHORT).show();
display_list(changed_text.toString(),changed_text.length(), NAME[0]);
}
});
}
/** displaying the list of the best match contacts */
public void display_list(final String searchString,int searchStringLength, final String actionTOPerform)
{
listview =(ListView)findViewById(android.R.id.list);
/** Defining the ArrayAdapter to set items to ListView */
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, list);
adapter.clear();
try {
phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
phones.moveToFirst();
while(phones.moveToNext())
{

if( (Name.toLowerCase()).contains(searchString.toLowerCase()) )
{
adapter.notifyDataSetChanged();
}
}

/** Setting the adapter to the ListView */
setListAdapter(adapter);

OnItemClickListener selectedItem = new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View selectedContact, int arg2,
long arg3) {
String callcontact = ((TextView)selectedContact).getText().toString();
phones.moveToFirst();

{
String Name=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

String url = "tel:"+Number;
Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(url));
startActivity(intent);
