Answer 1

您必须进行HTTP GET调用才能获得此字符串。您可以在android

中使用改装或排球或简单的HTTPConnection

这是一个示例代码

final TextView mTextView = (TextView) findViewById(R.id.text);
// ...

// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
String url ="http://www.google.com";

// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
        new Response.Listener<String>() {
@Override
public void onResponse(String response) {
    // Display the first 500 characters of the response string.
    mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
    mTextView.setText("That didn't work!");
}
});

// Add the request to the RequestQueue.
queue.add(stringRequest);

从URL获取字符串和数据并在我的UI中显示它
