Cordova调用Activity

首先需要编写一个CallActivityPlugin插件,专门调用Activity

 

 

1. package com.example.plugin;

2.  

3. import org.apache.cordova.api.CallbackContext;

4. import org.apache.cordova.api.CordovaPlugin;

5. import org.apache.cordova.api.PluginResult;

6. import org.json.JSONArray;

7. import org.json.JSONException;

8.  

9. import android.app.Activity;

10. import android.content.Intent;

11. import android.os.Bundle;

12. import android.util.Log;

13.  

14. public class CallActivityPlugin extends CordovaPlugin {

15. public static final String ACTION = "call";

16.  

17. @Override

18. public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {

19. if (action.equals(ACTION)) {

20. try {

21. //下面两句最关键，利用intent启动新的Activity

22. Intent intent = new Intent().setClass(cordova.getActivity(), Class.forName(args.getString(0)));

23. this.cordova.startActivityForResult(this, intent, 1);

24. //下面三句为cordova插件回调页面的逻辑代码

25. PluginResult mPlugin = new PluginResult(PluginResult.Status.NO_RESULT);

26. mPlugin.setKeepCallback(true);

27.  

28. callbackContext.sendPluginResult(mPlugin);

29. callbackContext.success("success");

30.  

31. } catch (Exception e) {

32. e.printStackTrace();

33. return false;

34. }

35. }

36.  

37. return true;

38. }

39. //onActivityResult为第二个Activity执行完后的回调接收方法

40. @Override

41. public void onActivityResult(int requestCode, int resultCode, Intent intent){

42. switch (resultCode) { //resultCode为回传的标记，我在第二个Activity中回传的是RESULT_OK

43. case Activity.RESULT_OK:

44. Bundle b=intent.getExtras(); //data为第二个Activity中回传的Intent

45. String str=b.getString("change01");//str即为回传的值

46. break;

47. default:

48. break;

49. }

50. }

51. }

 

 然后配置CallActivityPlugin插件res/xml/config.xml

 

接着利用js调用插件（callActivity.js）

 

window.callActivityPlugin = function(str,callback) {
	cordova.exec(callback, pluginFailed, "CallActivityPlugin", "call", [ str ]);
};

var pluginFailed = function(message) {
	alert("failed>>" + message);
}

$(function() {
	init();
});

var init = function() {
	console.log("phonegap init!!");
	document.addEventListener("deviceready", onDeviceReady, true);
}

var onDeviceReady = function() {
	
	console.log("deviceready event fired");

	window.callActivityPlugin("com.example.activity.MyActivity" , function(echoValue) {
		console.log("callActivityPlugin echo>>");
	});
};

 

最后html页面加载（相对简单）

11. callActivityPlugin

12. 返回

 

 

新的Activity代码（相对简单）

1. package com.example.activity;

2.  

3. import android.app.Activity;

4. import android.content.Context;

5. import android.content.Intent;

6. import android.net.Uri;

7. import android.os.Bundle;

8. import android.util.Log;

9. import android.view.View;

10. import android.view.View.OnClickListener;

11. import android.widget.Button;

12.  

13. import com.example.ask.R;

14.  

15. public class MyActivity extends Activity {

16. private Button btn;

17.  

18. private int flag = 0;

19.  

20. private Intent intentNew = null;

21.  

22. private Context context = this;

23.  

24. @Override

25. public void onCreate(Bundle savedInstanceState) {

26.  

27. super.onCreate(savedInstanceState);

28.  

29. setContentView(R.layout.my_activity_main);

30.  

31. intentNew = this.getIntent();

32.  

33. btn = (Button) findViewById(R.id.button1);

34.  

35. btn.setOnClickListener(new OnClickListener() {

36.  

37. public void onClick(View v) {

38. Intent mIntent = new Intent();

39. mIntent.putExtra("change01", "1000");

40. mIntent.putExtra("change02", "2000");

41. // 设置结果，并进行传送

42. setResult(RESULT_OK, mIntent);

43. finish();

44. }

45. });

46.  

47. }

48. }
