現在、Androidチャット画面アプリケーションで作業しています。TabHostを使用して5つのタブを設定し、ListActivityを使用してプロジェクトにListViewを作成しましたが、ListViewが全画面で表示されるため、高さを減らしたいのは、EditTextの下部を追加するためです。画面、助けてください。
前もって感謝します
私はあなたの参照のために以下に与えられたこれを試しました：
public class Texts extends ListActivity
{
String[] data={"How may i help you?", "Please help me", "Item 3","Item 1", "Item 2", "Item 3","Item 1", "Item 2", "Item 3"};

String bgimg = "",_user="",_pass="";
int odd_resID,even_resID;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
System.out.println(" CHAT SCREEN ");
//finding the list view
ListView myList = getListView();
myList.setAdapter(new MyCustomAdapter());
myList.setCacheColorHint(0);
// setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mListContent));
}
