android AsyncTask的简单用法

public class WeatherAsyncTask extends AsyncTask<String, Integer, String> {

	public TextView t1=null;
	
	public WeatherAsyncTask(TextView t)
	{
		t1=t;
	}
	
	@Override
	protected String doInBackground(String... params) {
		// TODO Auto-generated method stub
		return params[0];
	}

	@Override
	protected void onPostExecute(String result) {
		// TODO Auto-generated method stub
		super.onPostExecute(result);
		t1.setText(result);
	}
	
}
