Android 未在适当位置创建动态视图。重叠上一视图。安卓

我是Android新手，所以在过去的几天里我一直在努力调整，但我被困在这一部分。对于我的应用程序，我试图输入一个按钮“添加更多”，该按钮可以放大视图以帮助合并用户输入，但我遇到了一些问题。我环顾四周，利用他的帮助解决了我的问题，但我遇到了一个问题，我膨胀的xml布局与以前的设置布局重叠

这是我为新的\u类\u容器文件设置的布局

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/parentView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:animateLayoutChanges="true"
        android:orientation="vertical" 
        android:background="@drawable/gradient_gray">

<!-- Class Name -->

         <TextView
             android:id="@+id/register_class_textview"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="@string/write_class_name"

             android:textAppearance="?android:attr/textAppearanceMedium"
             android:textColor="#FFFFFF"/>

             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:layout_below="@+id/register_assign_textview"
             android:layout_alignLeft="@+id/register_assign_textview"

       <Button
           android:id="@+id/button_save"
           android:layout_width="fill_parent"
           android:layout_height="wrap_content"
           android:gravity="center"

       android:text="@string/more_assign"
       android:textColor="#FFFFFF" />

   <EditText
       android:id="@+id/register_weight_edit"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:layout_above="@+id/btnAddNewItem"

   <TextView
       android:id="@+id/register_weight_textview"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_alignBaseline="@+id/register_assign_textview"
       android:layout_alignBottom="@+id/register_assign_textview"
       android:layout_alignParentRight="true"
       android:text="@string/write_assign_percent"
       android:textAppearance="?android:attr/textAppearanceMedium" />

</RelativeLayout>

我能做些什么来防止它重叠并显示在下面？我怎样才能在每次“更新”时移动按钮？因为如果我将按钮移动到新的_类xml文件，那么最初添加更多视图时它将不会显示

我尝试实现下面的代码，它所做的是使我能够在第一次正确地添加动态视图，但每次都是在它与添加的视图重叠之后

RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
                ViewGroup.LayoutParams.WRAP_CONTENT);

        p.addRule(RelativeLayout.BELOW, R.id.register_assign_edit);

        rowView.setLayoutParams(p);

---

我不确定，但您可以尝试按照代码移动任何视图。我建议像主布局一样使用RelativeLayout

RelativeLayout.LayoutParams bParams1 = new RelativeLayout.LayoutParams(
                LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        bParams1.leftMargin = (int) leftMrgn;
        bParams1.topMargin = (int) topMgrn;
        bParams1.height = (int) bHeight;
        bParams1.width = (int) bWidth;
        anyView.setLayoutParams(bParams1);

---

RelativeLayout

s的行为类似于

FrameLayout

，如果您不给它们任何

LayoutParams

（下面、上面、中间等约束）

---

您可以构造适当的

RelativeLayout.LayoutParams

，或者在第一个布局中创建一个空的垂直

LinearLayout

，该布局将包含行。然后，只需将行添加到

线性布局

而不是

相对布局

，这将使用两个布局文件：

main\u layout

和

layout\u to\u include

main_layout.xml

很多代码。。。很多文字。。。简言之单击按钮时是否要向当前布局添加内容？是吗？@MateuszZając我要单击按钮，使其使用视图更新活动。在这种情况下，当用户按下“添加更多”按钮时，会显示额外的TextView和EditView。我在上面链接了一张图片，展示了它应该是什么样子。你想要的是在布局方面很容易做到，但很难管理。获取并跟踪所有输入将很困难。@vikram您能建议布局的方法吗？当然。我已经贴出了答案。看看它是否符合你的要求。
