如何在Android中显示进度条几秒钟，然后转到活动界面？

Question

我有一个活动，在服务器响应成功后，我想显示进度条几秒钟/几分钟，然后在几分钟后解除进度条并更改活动。我该怎么做？

以下是我的代码：

public void conditions() throws JSONException {
        if (m_oResponseobject.getString("resultdescription").equalsIgnoreCase("Transaction Successful")) {
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    CProgressBar.getInstance().showProgressBar(getApplicationContext(), "Please wait while rediecting to website");

                }
            }, 3000);
            CProgressBar.getInstance().hideProgressBar();
            Intent i = new Intent(CDealAppListingDetails.this, CMainActivity.class);
            startActivity(i);

        }
    }

Answer 1

int DELAY = 3000;
CProgressBar.getInstance().showProgressBar(getApplicationContext(), "Please wait while rediecting to website");

Handler handler = new Handler();
handler.postDelayed(new Runnable() {            
    @Override
    public void run() {
 CProgressBar.getInstance().hideProgressBar();
        Intent i = new Intent(CDealAppListingDetails.this, CMainActivity.class);
        startActivity(i);                
    }
}, DELAY);

试试这个：

     CProgressBar.getInstance().showProgressBar(getApplicationContext(), "Please wait while rediecting to website");
     new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        CProgressBar.getInstance().hideProgressBar();
                        Intent i = new Intent(CDealAppListingDetails.this, CMainActivity.class);
                        startActivity(i);
                    }
                }, 3000);
