//弹出加载中对话框
myProgressDialog=new WjProgressDialog(getActivity());
myProgressDialog.show();

public class WjProgressDialog extends ProgressDialog {

    public WjProgressDialog(Context context) {
        super(context, R.style.CustomProgressDialog);
    }

    public WjProgressDialog(Context context, int theme) {
        super(context, theme);
    }

    @Override
    public void show() {
        super.show();
        setContentView(R.layout.customprogressdialog);
    }

    @Override
    public void dismiss() {
        super.dismiss();
    }
}
