感觉现象很常见，也许大家还没发现，或着已经解决。
public class HeapTestActivity extends Activity {
TextView heapText;
/** Volley框架的请求队列 **/
public RequestQueue mRequestQueue ;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.heap_test);
mRequestQueue= Volley.newRequestQueue(this);
heapText=(TextView)findViewById(R.id.heapText);
getData();
}
String url="http://route.showapi.com/341-2";//笑话大全的API接口
HashMap<String, String> postMap;
public void getData() {
postMap = new HashMap<>();
postMap.put("showapi_appid", "10073");
postMap.put("showapi_sign", "8131cde1a4234008b25f2450e515607c");
postMap.put("showapi_timestamp", DateUtil.getOrderNum());
StringRequest arrayPostRequest = new StringRequest(Request.Method.POST,url, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
//请求成功
heapText.setText(response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
//请求错误
}
}) {
@Override
protected Map<String, String> getParams() {
return postMap;
}
};
arrayPostRequest.setTag("StringRequest");
mRequestQueue.add(arrayPostRequest);
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mRequestQueue.cancelAll(this);
}
}此代码大家可以直接COPY就能运行。
LeakCanary显示：StringRequest的参数，有个匿名内部类监听一直持有HeapTestActivity 这个对象，导致无法释放。
