Volley的使用

Volley加载图片到控件上

VolleyUtils.getLoader(getContext()).get(zixun.getPicurl(), ImageLoader.getImageListener(
imageView, R.drawable.ic_launcher, android.R.drawable.ic_menu_delete));

Volley加载

public void downTxt(View v){

//2. 实例化请求对象
StringRequest request=new StringRequest(url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// TODO 数据请求成功--》数据解析与展示
Toast.makeText(getApplicationContext(), "数据请求成功!", 1).show();
//4. 解析与展示
try {
JSONObject obj=new JSONObject(response);
JSONArray array=obj.getJSONArray("data");

parseJson(array);

} catch (JSONException e) {
e.printStackTrace();
}
}

}, null);

//3. 将请求添加到Volley的请求对列中
VolleyUtils.getQueue(getApplicationContext())
.add(request);

}

public void downJsonObject(View v){

//2. 实例化请求对象
JsonObjectRequest request=new JsonObjectRequest(Method.GET, url, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
// TODO 请求成功
try {
JSONArray array=response.getJSONArray("data");
parseJson(array);
} catch (JSONException e) {
e.printStackTrace();
}

}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "请求出错", 0).show();
}
});

//3. 将请求添加到Volley的请求对列中
VolleyUtils.getQueue(getApplicationContext()).add(request);
