早上好。 我想发送请求并在TextView中显示响应。使用异步Http客户端获得响应
public class MyHttpClient {
private static final String BASE_URL = "http://pgu.com";
private static AsyncHttpClient client = new AsyncHttpClient();
public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
client.get(getAbsoluteUrl(url), params, responseHandler);
}
private static String getAbsoluteUrl(String relativeUrl) {
return BASE_URL + relativeUrl;
}}
我打电话从这个类
public class MyHttpClientUsage {
Handler h;
public MyHttpClientUsage(Handler h){
this.h = h;
}
public void getInfoAbout() throws HttpException{
RequestParams params = new RequestParams();
params.put("a", "Static");
params.put("content", "47");
MyHttpClient.get("", params, new AsyncHttpResponseHandler(){
@Override
public void onSuccess(String response) {
System.out.println(response);
//Simplify sending int to TextView
MyHttpClientUsage.this.h.sendEmptyMessage(678);
}
});
}}
在活动我有一个处理程序获得的消息,并设置TextView的
public class MainActivity extends Activity {
Handler h;
TextView largeText;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
largeText = (TextView) findViewById(R.id.textView1);
h = new Handler(){
public void handleMessage(android.os.Message msg){
largeText.setText(msg.what);
}
};
MyHttpClientUsage connect = new MyHttpClientUsage(h);
try {
connect.getInfoAbout();
} catch (HttpException e) {
e.printStackTrace();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}}
在logcat中得到我有这个警告
02-06 14:30:51.783: W/dalvikvm(546): threadid=1: thread exiting with uncaught exception (group=0x409961f8)
和错误
02-06 14:30:51.833: E/AndroidRuntime(546): android.content.res.Resources$NotFoundException: String resource ID #0x2a6
你确定你已经宣布所有的意见? –
是的,我认为是。 – Valeriy
错误告诉我们找不到某些请求的资源。仔细检查你的xml布局并清理/重建你的项目。 –
