试试这个：

ProgressDialog progressDialog =  ProgressDialog.show(ExtractCallData.this, "title", "Message",true);

OR

ProgressDialog progress = new ProgressDialog(this);
progress.setTitle("Loading");
progress.setMessage("Wait while loading...");
progress.show();
// To dismiss the dialog
progress.dismiss();

Answer 3

progressDialog = new ProgressDialog(mContext);      
            progressDialog.setIndeterminate(true);
            progressDialog.setMessage(getResources().getString(R.string.scan_devices));
            progressDialog.show();

无论你使用什么，甚至在Android-M中都能正常工作，我认为你传递的Context的问题使用正确的上下文。一旦尝试下一个也

    public static ProgressDialog progress(Context context, String msg, boolean isCancelable) throws Exception {
    try {
        final ProgressDialog mProgressDialog = new ProgressDialog(context);
        mProgressDialog.setMessage(msg);
        mProgressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        mProgressDialog.setCancelable(isCancelable);
        mProgressDialog.setCanceledOnTouchOutside(isCancelable);
        mProgressDialog.show();
        mProgressDialog.setOnKeyListener(new OnKeyListener() {

            @Override
            public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) {
                if (keyCode == KeyEvent.KEYCODE_BACK) {
                    mProgressDialog.dismiss();
                }
                return false;
            }
        });

        return mProgressDialog;
    } catch (Exception e) {
        e.printStackTrace();
        throw e;
    }
}
