Artículo de fila personalizado de Android para ListView

Tengo un ListView que debe tener el siguiente diseño en sus filas:

HEADER Text 

HEADER debe ser estático, pero el Text cambia cada pocos segundos.

Lo implementé ArrayAdapter una String[] array , la ArrayAdapter a un ArrayAdapter y la configuré cada vez que los datos cambian:

 data_array = populateString(); adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, android.R.id.text1, data_array); listView.setAdapter(adapter); 

Mi problema es que no sé cómo mostrar los datos en el formato anterior.

Gracias por adelantado.

Agregue este row.xml a su carpeta de diseño

 < ?xml version="1.0" encoding="utf-8"?>     

hacer su diseño xml principal como este

 < ?xml version="1.0" encoding="utf-8"?>     

Este es tu adaptador

 class yourAdapter extends BaseAdapter { Context context; String[] data; private static LayoutInflater inflater = null; public yourAdapter(Context context, String[] data) { // TODO Auto-generated constructor stub this.context = context; this.data = data; inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { // TODO Auto-generated method stub return data.length; } @Override public Object getItem(int position) { // TODO Auto-generated method stub return data[position]; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub View vi = convertView; if (vi == null) vi = inflater.inflate(R.layout.row, null); TextView text = (TextView) vi.findViewById(R.id.text); text.setText(data[position]); return vi; } } 

Tu actividad java

 public class StackActivity extends Activity { ListView listview; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); listview = (ListView) findViewById(R.id.listview); listview.setAdapter(new yourAdapter(this, new String[] { "data1", "data2" })); } } 

Los resultados

Use una vista de lista personalizada.

También puede personalizar cómo se ve la fila al tener un fondo personalizado. activity_main.xml

 < ?xml version="1.0" encoding="utf-8"?>  //background color

Definir populateString () en MainActivity

  public class MainActivity extends Activity { String data_array[]; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); data_array = populateString(); ListView ll = (ListView) findViewById(R.id.list); CustomAdapter cus = new CustomAdapter(); ll.setAdapter(cus); } class CustomAdapter extends BaseAdapter { LayoutInflater mInflater; public CustomAdapter() { mInflater = (LayoutInflater) MainActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { // TODO Auto-generated method stub return data_array.length;//listview item count. } @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 0; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub final ViewHolder vh; vh= new ViewHolder(); if(convertView==null ) { convertView=mInflater.inflate(R.layout.row, parent,false); //inflate custom layour vh.tv2= (TextView)convertView.findViewById(R.id.textView2); } else { convertView.setTag(vh); } //vh.tv2.setText("Position = "+position); vh.tv2.setText(data_array[position]); //set text of second textview based on position return convertView; } class ViewHolder { TextView tv1,tv2; } } } 

row.xml. Diseño personalizado para cada fila.

crear archivo de diseño de recursos list_item.xml

 < ?xml version="1.0" encoding="utf-8"?>     

e inicialice un adaptador como este

 adapter = new ArrayAdapter(this, R.layout.list_item,R.id.item_text,data_array); 

Paso 1: crea un archivo XML

  < ?xml version="1.0" encoding="utf-8"?>    

Paso 2: Studnet.java

 package com.scancode.acutesoft.telephonymanagerapp; public class Student { String email,phone,address; public String getEmail() { return email; } public void setEmail(String email) { this.email = email; } public String getPhone() { return phone; } public void setPhone(String phone) { this.phone = phone; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } } 

Paso 3: MainActivity.java

  package com.scancode.acutesoft.telephonymanagerapp; import android.app.Activity; import android.os.Bundle; import android.widget.ListView; import java.util.ArrayList; public class MainActivity extends Activity { ListView lvItems; ArrayList studentArrayList ; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); lvItems = (ListView) findViewById(R.id.lvItems); studentArrayList = new ArrayList(); dataSaving(); CustomAdapter adapter = new CustomAdapter(MainActivity.this,studentArrayList); lvItems.setAdapter(adapter); } private void dataSaving() { Student student = new Student(); student.setEmail("abc@gmail.com"); student.setPhone("1234567890"); student.setAddress("Hyderabad"); studentArrayList.add(student); student = new Student(); student.setEmail("xyz@gmail.com"); student.setPhone("1234567890"); student.setAddress("Banglore"); studentArrayList.add(student); student = new Student(); student.setEmail("xyz@gmail.com"); student.setPhone("1234567890"); student.setAddress("Banglore"); studentArrayList.add(student); student = new Student(); student.setEmail("xyz@gmail.com"); student.setPhone("1234567890"); student.setAddress("Banglore"); studentArrayList.add(student); } } 

Paso 4: CustomAdapter.java

  package com.scancode.acutesoft.telephonymanagerapp; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.TextView; import java.util.ArrayList; public class CustomAdapter extends BaseAdapter { ArrayList studentList; Context mContext; public CustomAdapter(Context context, ArrayList studentArrayList) { this.mContext = context; this.studentList = studentArrayList; } @Override public int getCount() { return studentList.size(); } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { Student student = studentList.get(position); convertView = LayoutInflater.from(mContext).inflate(R.layout.student_row,null); TextView tvStudEmail = (TextView) convertView.findViewById(R.id.tvStudEmail); TextView tvStudPhone = (TextView) convertView.findViewById(R.id.tvStudPhone); TextView tvStudAddress = (TextView) convertView.findViewById(R.id.tvStudAddress); tvStudEmail.setText(student.getEmail()); tvStudPhone.setText(student.getPhone()); tvStudAddress.setText(student.getAddress()); return convertView; } } 

puede seguir BaseAdapter y crear su archivo Xml custome, BaseAdpter con BaseAdpter y BaseAdpter con BaseAdpter aquí debe cambiar el archivo xml como Require.
