如何在progressdialog dimiss上打开新活动？

以下是我的代码部分：

            @Override
        public void onClick(View v) {
            progressDoalog = new ProgressDialog(Hack.this);
            progressDoalog.setMax(100);
            progressDoalog.setMessage("Its loading....");
            progressDoalog.setTitle("ProgressDialog bar example");
            progressDoalog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            progressDoalog.show();
            new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        while (progressDoalog.getProgress() <= progressDoalog
                                .getMax()) {
                            Thread.sleep(200);
                            handle.sendMessage(handle.obtainMessage());
                            if (progressDoalog.getProgress() == progressDoalog
                                    .getMax()) {
                                progressDoalog.dismiss();
                            }
                        }
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }).start();
        }

        Handler handle = new Handler() {
            @Override
            public void handleMessage(Message msg) {
                super.handleMessage(msg);
                progressDoalog.incrementProgressBy(1);
            }
        };
    });
}

请帮帮我们。我认为这是在progressdialog完成后开放活动的一种解决方案。

只需添加：

progressDoalog.setOnDismissListener(new DialogInterface.OnDismissListener(){
            @Override
            public void onDismiss(DialogInterface dialog) {
                //Launch your activity
            }
        });

这是一个简单的监听器，在你的对话解雇时调用

您可以使用AsyncTask

在AsyncTask中有三种重要的方法可以覆盖。

doInBackground ：这是您进行背景处理的主要原因。
onPreExecute ：在此处显示您的ProgressDialog（showDialog）
onPostExecute ：在此处隐藏您的ProgressDialog（removeDialog或dismissDialog）

如果将AsyncTask子类作为活动的内部类，则可以在AsyncActivity中调用框架方法showDialog，dismissDialog和removeDialog。

以下是AsyncTask的示例实现：

class ProgressTask extends AsyncTask<String, Integer, Boolean> {
  @Override
  protected Boolean doInBackground(String... params) {
    try {
      Thread.sleep(4000);  // Do your real work here
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
    return Boolean.TRUE;   // Return your real result here
  }
  @Override
  protected void onPreExecute() {
    showDialog(AUTHORIZING_DIALOG);
  }
  @Override
  protected void onPostExecute(Boolean result) {
    // result is the value returned from doInBackground
    removeDialog(AUTHORIZING_DIALOG);
    Intent i = new Intent(this, LandingActivity.class);
    startActivity(i);
  }
}

@MarkusMaleńki请参考下面的代码

if(progressDoalog!=null && progressDoalog.isShowing()){
  progressDoalog.setOnDismissListener(new 
  DialogInterface.OnDismissListener(){
  @Override
    public void onDismiss(DialogInterface dialog) {
    //Launch your activity
   }
});

}
