推荐答案

我终于通过重写自定义对话框的show()方法解决了这个问题.

I finally solved this by overriding the show() method of the custom dialog that I have.

@Override
public void show() {
    // Set the dialog to not focusable.
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
            WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);

    // Show the dialog with NavBar hidden.
    super.show();

    // Set the dialog to focusable again.
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
}
