android开发 phonegap插件开发中ProgressDialog的使用

整体来说，android开发编写java代码比较变态。

在使用phonegap开发插件是则会让你看到更变态的用法。

 

直接贴代码吧，为走弯路的朋友借鉴。

代码参考phonegap源码Notification.java类

 

 

package com.p3p.android.plugin;

import org.json.JSONArray;
import org.json.JSONException;

import android.app.ProgressDialog;

import com.phonegap.api.PhonegapActivity;
import com.phonegap.api.Plugin;
import com.phonegap.api.PluginResult;

public class HelloWord extends Plugin {
 public ProgressDialog progressDialog = null;

 @SuppressWarnings("static-access")
 @Override
 public PluginResult execute(String arg0, JSONArray arg1, String arg2) {
  // TODO Auto-generated method stub
  PluginResult.Status status = PluginResult.Status.OK;
  String result = "";
  try {

   if (this.progressDialog != null) {
    this.progressDialog.dismiss();
    this.progressDialog = null;
   }
   final HelloWord __this = this;
   final PhonegapActivity ctx = this.ctx;
   Runnable runnable = new Runnable() {
    public void run() {
     __this.progressDialog = new ProgressDialog(ctx);
     __this.progressDialog
       .setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
     __this.progressDialog.setTitle("提示信息");
     __this.progressDialog.setMessage("文件正在下载中，请稍微...");
     __this.progressDialog.setCancelable(false);
     //__this.progressDialog.setCancelable(true);
     __this.progressDialog.setMax(100);
     __this.progressDialog.setProgress(0);
     /*
      * __this.progressDialog .setOnCancelListener(new
      * DialogInterface.OnCancelListener() { public void
      * onCancel(DialogInterface dialog) { __this.progressDialog
      * = null; } });
      */
     __this.progressDialog.show();
    }
   };

   this.ctx.runOnUiThread(runnable);
   Thread.currentThread().sleep(2000l);
   this.progressDialog.setProgress(80);
   Thread.currentThread().sleep(3000l);
   this.progressDialog.setProgress(95);
   Thread.currentThread().sleep(1000l);
   this.progressDialog.setProgress(100);
   Thread.currentThread().sleep(1000l);
   this.progressDialog.dismiss();
    result = "result from my plugin:" + arg1.getString(0);
  } catch (JSONException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (InterruptedException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  return new PluginResult(status, result);

 }

}
