我試圖在Android Studio中練習使用GridView，我不知道爲什麼我不斷收到這個異常。爲什麼我的GridView不起作用？
這是我的主要類的代碼。
public class MainActivity extends AppCompatActivity {
private GridView turtle;
private List<Map<String,Object>> datalist;
private int[] icon = {R.drawable.address_book,R.drawable.calendar,R.drawable.camera,R.drawable.clock,R.drawable.games_control,R.drawable.messenger,R.drawable.ringtone,R.drawable.settings,R.drawable.speech_balloon,R.drawable.weather,R.drawable.world,R.drawable.youtube};
private String [] iconName = {"Contackt","Calendar","Camera","Clock","game","messager","ring","setting","voice","weather","browser","video"};
private SimpleAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
turtle = (GridView) findViewById(R.id.turtle);
datalist = new ArrayList<Map<String,Object>>();
adapter = new SimpleAdapter(this,getdata(),R.layout.item,new String[]{"pic","txt"}, new int[]{R.id.pic,R.id.text});
turtle.setAdapter(adapter);
}
private List<Map<String,Object>> getdata(){
for(int i = 0; i<icon.length;i++) {
Map<String, Object> map = new HashMap<String, Object>();
map.put("pic", icon[i]);
map.put("text",iconName[i]);
datalist.add(map);
}
return datalist;
}
}
這裏是我的主XML文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.jinyu.gridleview.MainActivity">
<GridView
android:numColumns="3"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/turtle"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
下面的代碼是我的項目佈局的代碼：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:gravity="center"
>
<ImageView
android:src="@drawable/ic_launcher"
android:id="@+id/pic"
android:layout_width="60dp"
android:layout_height="60dp" />
<TextView
android:layout_marginTop="5dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#ffffff"
android:id="@+id/text"
android:text="text"
android:textSize="12dp"/>
</LinearLayout>

顯示適配器代碼。 –
adapter = new SimpleAdapter（this，getdata（），R.layout.item，new String [] {「pic」，「txt」}，new int [] {R.id.pic，R.id.text}） ;這個？ –
問題是Outofmemory不是適配器。你有沒有在Android中表現出大堆？ –
