添加更多项目,只需在String数组中添加更多url。
private String urls[] = {
"http://farm7.staticflickr.com/6101/6853156632_6374976d38_c.jpg",

};
它会自动拍摄新照片...
已编辑:
如果您使用了List<String>
,那么..添加网址如下
List<String> flavours = new ArrayList<String>();
flavours.add("http://farm8.staticflickr.com/7084/6885444694_6272874cfc.jpg");
flavours.add("http://farm8.staticflickr.com/7251/7059629417_e0e96a4c46.jpg");
flavours.add("http://farm8.staticflickr.com/7086/7238812536_1334d78c05.jpg");

是的,我确实在onCreate中使用了相同的内容。
结束然后,我调用菜单项,使用AsyncTask,dapter.notifyDataSetChanged();单击为list_url添加更多项目URL。
错误==&gt;内存不足:堆大小= 65571KB,分配= 62049KB,限制= 65536KB
private ArrayList<String> urllinks;
private StaggeredGridView gridView;
private StaggeredGridViewAdapter adapter;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gridView = (StaggeredGridView ) this.findViewById(R.id.staggeredGridView1);
int margin = getResources().getDimensionPixelSize(R.dimen.margin);
gridView.setItemMargin(margin);
gridView.setPadding(margin, 0, margin, 0);
urllinks = new ArrayList<String>();
for (int i = 1; i < 50; i++) {
urllinks.add("http://ecooking.tuyn.info/image/food/" + i + "/"
+ "name" + i + ".png");
}
adapter = new StaggeredGridViewAdapter(MainActivity.this, R.id.imageView1,
urllinks);
gridView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
public boolean onMenuItemSelected(int featureId, MenuItem itemmenu) {
int itemId = itemmenu.getItemId();
switch (itemId) {
case R.id.menu_add_new_item:
new GetDataTask().execute();
break;
}
return true;
}
private class GetDataTask extends AsyncTask<Void, Void, String> {
@Override
protected String doInBackground(Void... params) {
// a background job.
for (int i = urllinks.size(); i < urllinks.size() + 2; i++) {
urllinks.add("http://ecooking.tuyn.info/image/food/" + i
+ "/" + "name" + i + ".png");
}
return null;
}
@Override
protected void onPostExecute(String result) {
adapter.notifyDataSetChanged();
super.onPostExecute(result);
}
}
谢谢
