[英]Save the response from OkHttp — Android --
I wanna to save the result from OnResponse method to use it for updating the UI i tried to save the result into String var then call it into main thread but it doesn't work . 我想从OnResponse方法中保存结果以用于更新UI,我试图将结果保存到String var中,然后将其调用到主线程中,但它不起作用。
here's my code with some comments , any help ? 这是我的代码,带有一些注释,有帮助吗?
package com.example.blacknight.testokhttp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import java.io.IOException;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import static android.R.string.ok;
public class MainActivity extends AppCompatActivity {
public final String URL_MOVIE = "http://api.themoviedb.org/3/movie/popular?api_key=" + API_KEY;
String res_120 ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(URL_MOVIE)
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
Log.v("BK-201 URL: " , response.body().string());
// wanna save the result to update UI
res_120 = response.body().string();
}
});
// just for test : if the result has been saved or not
Log.i("BK-111 : " , res_120);
}
} }
Let's say you want to update a TextView element in you UI with the response in a String format. 假设您要使用字符串格式的响应来更新UI中的TextView元素。 You could do something like this.
你可以做这样的事情。 I keeped your test log to help you follow the code, just in case.
我保留了您的测试日志以帮助您遵循代码,以防万一。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(URL_MOVIE)
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException {
Log.v("BK-201 URL: " , response.body().string());
// wanna save the result to update UI
res_120 = response.body().string();
updateUI(response.body().string());
}
});
}
void updateUI(String string) {
textView.setText(string);
Log.i("BK-111 : " , res_120);
}
Here's a working code for anyone have the same problem or new on using OkHttp , Unfortunately i'm using AsyncTask 这是一个有效的代码,适用于任何有相同问题或使用OkHttp的新人,不幸的是,我正在使用AsyncTask
