Android PhoneGap（Cordova）彈出軟鍵盤功能

Android PhoneGap（Cordova）彈出軟鍵盤功能，利用PhoneGap怎麼去實現，純屬娛樂.

1.首先是phonegap必備的兩個文件，分別是本地.java代碼SoftKeyBoard.java

1. package com.tricedesigns;
3. import org.json.JSONArray;
5. import android.content.Context;
6. import android.view.inputmethod.InputMethodManager;
8. import com.phonegap.api.Plugin;
9. import com.phonegap.api.PluginResult;
11. public class SoftKeyBoard extends Plugin {
13. public SoftKeyBoard() {
14. }
16. public void showKeyBoard() {
17. InputMethodManager mgr = (InputMethodManager) ((Context) this.ctx).getSystemService(Context.INPUT_METHOD_SERVICE);
18. mgr.showSoftInput(webView, InputMethodManager.SHOW_IMPLICIT);
20. ((InputMethodManager) ((Context) this.ctx).getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(webView, 0);
21. }
23. public void hideKeyBoard() {
24. InputMethodManager mgr = (InputMethodManager) ((Context) this.ctx).getSystemService(Context.INPUT_METHOD_SERVICE);
25. mgr.hideSoftInputFromWindow(webView.getWindowToken(), 0);
26. }
28. public boolean isKeyBoardShowing() {
30. int heightDiff = webView.getRootView().getHeight() - webView.getHeight();
31. return (100 < heightDiff); // if more than 100 pixels, its probably a keyboard...
32. }
34. public PluginResult execute(String action, JSONArray args, String callbackId) {
35. if (action.equals("show")) {
36. this.showKeyBoard();
37. return new PluginResult(PluginResult.Status.OK, "done");
38. }
39. else if (action.equals("hide")) {
40. this.hideKeyBoard();
41. return new PluginResult(PluginResult.Status.OK);
42. }
43. else if (action.equals("isShowing")) {
45. return new PluginResult(PluginResult.Status.OK, this.isKeyBoardShowing());
46. }
47. else {
48. return new PluginResult(PluginResult.Status.INVALID_ACTION);
49. }
50. }
51. }

2.(.js文件share.js)其中的一個顯示方法

1. var SoftKeyBoard={
2. skbShow:function(win, fail){
3. return cordova.exec(
4. function (args) { if(win !== undefined) { win(args); } },
5. function (args) { if(fail !== undefined) { fail(args); } },
6. "SoftKeyBoard",
7. "show",
8. []);
9. }
10. }
12. /*function SoftKeyBoard() {}
15. SoftKeyBoard.prototype.show = function(win, fail) {
16. return PhoneGap.exec(
17. function (args) { if(win !== undefined) { win(args); } },
18. function (args) { if(fail !== undefined) { fail(args); } },
19. "SoftKeyBoard",
20. "show",
21. []);
22. };
24. SoftKeyBoard.prototype.hide = function(win, fail) {
25. return PhoneGap.exec(
26. function (args) { if(win !== undefined) { win(args); } },
27. function (args) { if(fail !== undefined) { fail(args); } },
28. "SoftKeyBoard",
29. "hide",
30. []);
31. };
33. SoftKeyBoard.prototype.isShowing = function(win, fail) {
34. return PhoneGap.exec(
35. function (args) { if(win !== undefined) { win(args); } },
36. function (args) { if(fail !== undefined) { fail(args); } },
37. "SoftKeyBoard",
38. "isShowing",
39. []);
40. };
42. PhoneGap.addConstructor(function() {
43. PhoneGap.addPlugin('SoftKeyBoard', new SoftKeyBoard());
44. PluginManager.addService("SoftKeyBoard","com.zenexity.SoftKeyBoardPlugin.SoftKeyBoard");
45. });
46. */
