Question

在我的下面的代码中，在用户单击“Check For Root”后，我想要一个微调器样式进程对话框，持续5秒。基本上在用户点击按钮后，进程对话框将显示“Please wait ...”5秒钟，然后显示结果。我怎么做？请帮忙！

Button Root = (Button) findViewById(R.id.Root);
    Root.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            if (RootTools.isAccessGiven()) {
                    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                    builder.setIcon(R.drawable.ic_launcher);
                    builder.setTitle("Congratulations!");
                    builder.setMessage("You Have Root Access!");

                    builder.setPositiveButton("OKAY", new DialogInterface.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dialog.cancel();
                        }
                    });

                    AlertDialog dialog = builder.create();
                    dialog.show();
                }

            else  {
                 AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                    builder.setIcon(R.drawable.ic_launcher);
                    builder.setTitle("Oops!");
                    builder.setMessage("No Root Access!");
                    builder.setPositiveButton("OKAY", new DialogInterface.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialog, int which) {

                            dialog.cancel();
                        }
                    });

                    AlertDialog dialog = builder.create();
                    dialog.show();  
            }
        }

    @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState); 

            setContentView(R.layout.splashscreen_layout);

            ProgressDialog progressDialog;
            progressDialog = new ProgressDialog(BrandList.this);
            progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
            progressDialog.setMessage("Loading...");
            progressDialog.setCancelable(false);
            progressDialog.show();

            Thread thread = new Thread() {

                @Override
                public void run() {

                    try {
                        synchronized (this) {
                            wait(5000); // the time in millis.
                        }
                    } catch (InterruptedException e) {


                    } finally {
                         progressDialog.dismiss();
                        //do your stuff.

                    }

                }

您可以使用Jquery加载器来实现此目的。找到Jquery加载器JS和Jquery CSS并将它们包含在您的应用程序中。

在页面加载

上编写此代码

$.loader({
className:"blue-with-image-2",
content:''
});
write this after the query or process is completed:


$.loader('close');

这会在完成此过程后关闭加载程序。您也可以放置一些文本而不是加载器。希望这有帮助
