import java.util.ArrayList;
import java.util.HashMap;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.SimpleAdapter;
public class ItemActivity extends Activity {
private ListView listView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
listView = (ListView)findViewById(R.id.chat1);
ArrayList<HashMap<String, Object>> listItem = new ArrayList<HashMap<String,Object>>();
// for (int i = 0; i < 5; i++) {
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("name", "name");
map.put("time", "time" );
map.put("message", "message");
listItem.add(map);
// }
SimpleAdapter simpleAdapter = new SimpleAdapter(this,listItem,
R.layout.chat_item,
new String[]{"name","time","message" },
new int[]{R.id.show_name,R.id.show_time,R.id.message}
);
listView.setAdapter(simpleAdapter);
}
}
以上是activity的代码
下面是listview的chat.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ListView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/chat1"
/>
</LinearLayout>
然后是自定义布局chat_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="6dip" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:id="@+id/show_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="asassa"
/>
<TextView android:id="@+id/show_time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0"
android:text="asassa"
/>
</LinearLayout>
<TextView android:id="@+id/message"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="asassa"
/>
</LinearLayout>
