Question

我有一个线性布局，用户可以动态地向其插入元素以发送到服务器，我计划在用户单击发送按钮后有一个确认对话框。在对话框中，我想再次显示布局。我可以以某种方式克隆或移动视图到新的对话框，而不是再次进行。

Answer 1

    ViewGroup viewRoot =  (ViewGroup)LayoutInflater.from(this).inflate(R.layout.dialog_example, null);
    //you can measure the width of viewRoot,if the width is specified
    int measuredWidth = DimenUtil.getMeasuredWidth(viewRoot);
    int measuredHeight = DimenUtil.getMeasuredHeight(viewRoot);

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    AlertDialog dialog = builder.create();
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setCanceledOnTouchOutside(true);

/ ** 你应该在setContentView（int layout）之前执行语句，否则会发生AndroidRuntimeException，因为在添加内容之前必须调用requestFeature（），我也对这个原因感到困惑 ** /

    dialog.show();
    dialog.setContentView(viewRoot);
    Window window = dialog.getWindow();
    window.setGravity(gravity);
    window.setLayout(measuredWidth, measuredHeight);
