我正试图从rest API得到响应，并且我已经按照API文档和凌空文档的所有步骤进行了操作。但这似乎每次都会出错。
我已经在浏览器中直接尝试了API URL，并且响应很好，这意味着我的代码中肯定有错误。
public class MainActivity extends AppCompatActivity {
public void apiclick(View view) throws JSONException {
final TextView textView = (TextView) findViewById(R.id.TextView);
textView.setMovementMethod(new ScrollingMovementMethod());
VolleyLog.DEBUG = true;
// ...
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(MainActivity.this);
EditText query = (EditText)findViewById(R.id.query);
String jeff = query.getText().toString();
final String key = "796c9ca2788d1e243f8ec9e8e67acb33";
String url = ("https://api.themoviedb.org/3/search/movie?page=1&query=avengers&api_key=796c9ca2788d1e243f8ec9e8e67acb33" );
// Request a string response from the provided URL.
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
// Display the first 1000 characters of the response string.
textView.setText("Response is: " + response.toString());
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
textView.setText("Error");
}
});
// Add the request to the RequestQueue.
queue.add(jsonObjectRequest);
这是我的日志输出。
