我找到了 Fedor 的代码并在我的项目中实现了它。唯一的区别是我的应用程序没有列表视图。
我希望显示器看起来像这样:
我怎样才能做到这一点?
ImageAdapter.class
public class ImageAdapter extends BaseAdapter {
private Activity activity;
// private Context context;
private ArrayList<HashMap<String, String>> data;
// private int mThumbIds = (R.drawable.stub);
private static LayoutInflater inflat = null;
public Image image;
public ImageAdapter(Activity ac, ArrayList<HashMap<String, String>> d) {
this.activity = ac;
this.data = d;
inflat = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
image = new Image(activity);
}
public int getCount() {
// TODO Auto-generated method stub
return data.size();
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View view = convertView;
if (convertView == null) {
view = inflat.inflate(R.layout.items, null);
}
ImageView images = (ImageView) view.findViewById(R.id.item);
HashMap<String, String> imageMap = new HashMap<String, String>();
imageMap = data.get(position);
images.setImageResource(R.id.item);
image.DisplayImage(imageMap.get("SOURCE"), images);
return view;
}
MoiNhatAct.class
public class MoiNhatAct extends Activity {
private static String url1 = "http://beta.photo.tamtay.vn/service/detail/getPhotoNews/4";
GridView g;
ImageAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stubs
super.onCreate(savedInstanceState);
setContentView(R.layout.aaa);
ArrayList<HashMap<String, String>> imageList = new ArrayList<HashMap<String, String>>();
// Creating JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON string from URL
JSONObject json = jParser.getJSONFromUrl(url1);
JSONObject result;
try {
result = json.getJSONObject("result");
String data_time = result.getString("Date time");
String count = result.getString("Count");
String page = result.getString("page");
JSONArray ketqua = result.getJSONArray("ketqua");
for (int i = 0; i < ketqua.length(); i++) {
JSONObject j = ketqua.getJSONObject(i);
String id = j.getString("id");
String name = j.getString("name");
String thumb = j.getString("thumb");
String source = j.getString("source");
JSONArray sizeArray = j.getJSONArray("size");
String size = sizeArray.getString(0);
HashMap<String, String> map = new HashMap<String, String>();
map.put("DATE_TIME", data_time);
map.put("COUNT", count);
map.put("PAGE", page);
map.put("ID", id);
map.put("NAME", name);
map.put("SOURCE", source);
map.put("SIZE", size);
imageList.add(map);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
g = (GridView) findViewById(R.id.gridAvarta);
adapter = new ImageAdapter(this, imageList);
g.setAdapter(adapter);
g.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v,
int position, long id) {
Intent i = new Intent(getApplicationContext(),
ImageFullAct.class);
// passing array index
i.putExtra("id", position);
startActivity(i);
}
});
Button clear = (Button) findViewById(R.id.clearCache);
clear.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
adapter.image.clearCache();
adapter.notifyDataSetChanged();
}
});
}
public void onDestroy() {
g.setAdapter(null);
super.onDestroy();
}
}
这段代码我可以使用 Gridview 显示图像。
但我可以自定义它看起来像下面的布局
现在我需要一个自定义布局和显示
