我有一個要求,我必須獲取在編輯文本中輸入的URL地址的來源。能夠獲取在HTTPGET請求中硬編碼的URL的源文件。代碼如下..獲取在編輯文本中輸入的URL的來源
public String getHtml() throws ClientProtocolException, IOException
{
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("http://www.google.com");
HttpResponse response = httpClient.execute(httpGet, localContext);
BufferedReader reader = new BufferedReader(
new InputStreamReader(
response.getEntity().getContent()
)
);
String line = null;
while ((line = reader.readLine()) != null){
result += line + "\n";
Log.d("result","="+result);
}
return result;
}
並將其保存在文件中,如:
public void onClick(View v) {
File file = new File(etPath.getText().toString());
FileWriter writer=null;
try
{
writer = new FileWriter(file);
/** Saving the contents to the file*/
writer.write(getHtml());
/** Closing the writer object */
writer.close();
/** Getting sharedpreferences object to store the path of last saved file */
SharedPreferences.Editor editor = getPreferences(MODE_PRIVATE).edit();
/** Setting the last saved file's path in the shared preference */
editor.putString("fpath", file.getPath());
/** Save the path to the shared preference */
editor.commit();
Toast.makeText(getBaseContext(), "Successfully saved", Toast.LENGTH_SHORT).show();
} catch (IOException e) {
e.printStackTrace();
}
}
};
這種方法是正確的返回google.com的來源。 但我需要做這樣的事情:
HttpGet httpGet = new HttpGet(etContent.getText().toString());
凡etContent是正在其中輸入網址的編輯文本。 但是當我執行這個語句時,它會崩潰。
我需要提取編輯文本中輸入的URL的來源。我不打算使用異步任務。請幫幫我。
請張貼一些支持的代碼。謝謝
