我只是問自己是否有一種方法讓ListView沒有任何文本。我只找到了帶有圖像+文本的ListView,而這正是我不想要的。我只想添加很多像列表中的圖像,並且不想用ImageView製作圖像,因爲這會導致我的應用程序崩潰。另外,我不希望我的應用程序滯後。謝謝!ListView僅限圖像
這是我在activity_main.xml中
<ListView
android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
了,我發現從另一個職位,實際上幫助了我,但它不顯示所有圖像
public class MainActivity extends Activity {
// Array of integers points to images stored in /res/drawable-hdpi/
int[] vehs = new int[]{
R.drawable.veh1,
R.drawable.veh2,
R.drawable.veh3,
R.drawable.veh4,
R.drawable.veh5,
R.drawable.veh6,
R.drawable.veh7,
R.drawable.veh8,
R.drawable.veh9,
R.drawable.veh10,
R.drawable.veh11,
R.drawable.veh12,
R.drawable.veh13,
R.drawable.veh14,
R.drawable.veh15,
R.drawable.veh16,
R.drawable.veh17,
R.drawable.veh18,
R.drawable.veh19,
R.drawable.veh20,
R.drawable.veh21,
R.drawable.veh22,
R.drawable.veh23,
R.drawable.veh24,
R.drawable.veh25,
R.drawable.veh26,
R.drawable.veh27,
R.drawable.veh28,
R.drawable.veh29,
R.drawable.veh30,
R.drawable.veh31,
R.drawable.veh32,
R.drawable.veh33,
R.drawable.veh34,
R.drawable.veh35,
R.drawable.veh36,
};
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Each row in the list stores country name, currency and flag
List<HashMap<String,String>> aList = new ArrayList<HashMap<String,String>>();
for(int i=0;i<10;i++){
HashMap<String, String> hm = new HashMap<String,String>();
hm.put("vehs", Integer.toString(vehs[i]));
aList.add(hm);
}
// Keys used in Hashmap
String[] from = { "vehs","txt","cur" };
// Ids of views in listview_layout
int[] to = { R.id.vehs,R.id.txt,R.id.cur};
// Instantiating an adapter to store each items
// R.layout.listview_layout defines the layout of each item
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.listview_layout, from, to);
// Getting a reference to listview of main.xml layout file
ListView listView = (ListView) findViewById(R.id.listview);
// Setting the adapter to the listView
listView.setAdapter(adapter);
}
}
沒有編輯所有的代碼,所以你可能會發現一些令人困惑的東西xD
你可以發佈您的代碼? –
一些代碼會幫助我理解你的觀點:) –
@mohammedmomn我其實沒有代碼,希望你能告訴我一個基本的地方,我可以添加圖像。 –
