Android WebView加載HTML表單並通過javascript提交（三）

1. public class WebViewTest extends Activity {
   
2. private WebView mWebView = null;
   
3. private TextView txtView = null;
   
4. private Handler mHandler = new Handler();
   
5. /** Called when the activity is first created. */
   
6. @Override
   
7. public void onCreate(Bundle savedInstanceState) {
   
8. super.onCreate(savedInstanceState);
   
9. setContentView(R.layout.main);
   
10. mWebView = (WebView) findViewById(R.id.webView);
    
11. txtView = (TextView) findViewById(R.id.webViewResult);
    
12. WebSettings webSettings = mWebView.getSettings();
    
13. //不保存密碼
    
14. webSettings.setSavePassword(false);
    
15. //不保存表單數據
    
16. webSettings.setSaveFormData(false);
    
17. webSettings.setJavaScriptEnabled(true);
    
18. //不支持頁面放大功能
    
19. webSettings.setSupportZoom(false);
    
20. mWebView.addJavascriptInterface(new LoginJavaScriptImpl(), "loginImpl"); mWebView.setWebChromeClient(new MyAndroidWebClient());
    
21. ((Button)findViewById(R.id.btnLoadhtml)).setOnClickListener(new View.OnClickListener() {
    
22. public void onClick(View arg0) {
    
23. mWebView.loadData(createWebForm(), "text/html", "UTF-8");
    
24. // mWebView.loadDataWithBaseURL("", createWebForm(), "text/html", "UTF-8", "");
    
25. }
    
26. });
    
27. }
    
28. private String returnValue;
    
29. protected final class LoginJavaScriptImpl {
    
30. public void login(String username, String password){
    
31. returnValue = username + ": " + password; mHandler.post(new Runnable() {
    
32. public void run() { txtView.setText(returnValue);
    
33. }
    
34. });
    
35. }
    
36. }
    
37. private final class MyAndroidWebClient extends WebChromeClient {
    
38. 
    
39. @Override
    
40. public boolean onJsAlert(WebView view,String url, String message, JsResult result) {
    
41. new AlertDialog.Builder(WebViewTest.this) .setTitle("提示訊息") .setMessage(message) .setPositiveButton("確定", new DialogInterface.OnClickListener() {
    
42. public void onClick( DialogInterface dialoginterface, int i) { }
    
43. }).show();
    
44. return true;
    
45. }
    
46. 
    
47. }
