java - 将网页文本放入 TextView (Android)

Question

我想将网页中的文本放入 Android 3.0 上的 TextView 中。我有这个代码:

public class Biografie extends Activity {
    private TextView outtext;
    private String HTML;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_biografie);

        outtext= (TextView) findViewById(R.id.textview1); 

        try { 
        getHTML();
    } catch (Exception e) {
        e.printStackTrace();
    }       
    outtext.setText("" + HTML);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.biografie, menu);
        return true;
    }

    private void getHTML() throws ClientProtocolException, IOException 

    {
        HttpClient httpClient = new DefaultHttpClient();
        HttpContext localContext = new BasicHttpContext();
        HttpGet httpGet = new HttpGet("http://artistone.appone.nl/api/biografie.php?dataid=998"); //URL!
        HttpResponse response = httpClient.execute(httpGet, localContext);
        String result = "";

        BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

        String line = null;
        while ((line = reader.readLine()) != null) {
            result += line + "\n";
            HTML = result;
        }

    }

}

我的 TextView 返回“null”而不是页面中的文本。请帮我解决这个问题。谢谢您的关注。

将代码更改为:

while ((line = reader.readLine()) != null) {
    result += line + "\n";
}
HTML = result;

并尝试这个:outtext.setText(Html.fromHtml(HTML));

我建议您使用 AsyncTask 在单独的线程中执行此操作，而不是在主线程中执行网络操作
