memasukkan data ke listview
Buat project baru di android, dan buat activity baru, di Main Activity isi kode berikut :
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Vector;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import android.os.Bundle;
import android.app.Activity;
import android.app.ListActivity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.*;
public class MainActivity extends ListActivity
{
EditText text;
Button ok;
ArrayAdapter Ardapter;
Vector v = new Vector();
String isi;
List<String> data = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text= (EditText) findViewById(R.id.inputSearch);
ok= (Button) findViewById(R.id.button1);
ListView lv = getListView();
lv = getListView();
Ardapter =new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data);
lv.setAdapter(Ardapter);
ok.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View currentView)
{
String input = text.getText().toString();
if(null!=input&&input.length()>0){
data.add(input);
Ardapter.notifyDataSetChanged();
text.setText("");
}
};
});
}
}
lalu untuk view, ActivityMain.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="@id/android:list"
android:layout_width="fill_parent"
android:layout_height="242dp"
android:layout_weight="0.12"
android:drawSelectorOnTop="false" />
<TextView
android:id="@id/android:empty"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="No data" />
<EditText
android:id="@+id/inputSearch"
android:layout_width="match_parent"
android:layout_height="50dp"
android:ems="10"
android:hint="ketik di sini.."
android:inputType="textVisiblePassword" >
<requestFocus />
</EditText>
<Button
android:id="@+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Ok" />
</LinearLayout>
