Android URLconnection
使用Thread请求HTTP
普通的使用java的Thread 线程,在重写run 方法,实现HTTPConnection
public class DoubleMeActivity extends Activity implements OnClickListener {
EditText inputValue=null;
Integer doubledValue =0;
Button doubleMe;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.calculate);
inputValue = (EditText) findViewById(R.id.inputNum);
doubleMe = (Button) findViewById(R.id.doubleme);
doubleMe.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.doubleme:
new Thread(new Runnable() {
public void run() {
try{
URL url = new URL("http://10.0.2.2:8080/MyServletProject/DoubleMeServlet");
URLConnection connection = url.openConnection();
String inputString = inputValue.getText().toString();
//inputString = URLEncoder.encode(inputString, "UTF-8");
Log.d("inputString", inputString);
connection.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(connection.getOutputStream());
out.write(inputString);
out.close();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String returnString="";
doubledValue =0;
while ((returnString = in.readLine()) != null)
{
doubledValue= Integer.parseInt(returnString);
}
in.close();
runOnUiThread(new Runnable() {
public void run() {
inputValue.setText(doubledValue.toString());
}
});
}catch(Exception e)
{
Log.d("Exception",e.toString());
}
}
}).start();
break;
}
}
}
