Hi You can try this way by adding relative layout and than add textview in that. 

<pre><code>LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
 (LayoutParams.WRAP_CONTENT), (LayoutParams.WRAP_CONTENT));

RelativeLayout relative = new RelativeLayout(getApplicationContext());
relative.setLayoutParams(lp);

TextView tv = new TextView(getApplicationContext());
tv.setLayoutParams(lp);

EditText edittv = new EditText(getApplicationContext());
edittv.setLayoutParams(lp);

relative.addView(tv);
relative.addView(edittv);
</code></pre>

<code>ViewParent</code>s in general can't remove views, but <code>ViewGroup</code>s can. You need to cast your parent to a <code>ViewGroup</code> (if it is a <code>ViewGroup</code>) to accomplish what you want. 

For example:

<pre><code>View namebar = View.findViewById(R.id.namebar);
((ViewGroup) namebar.getParent()).removeView(namebar);
</code></pre>

Note that all <code>Layout</code>s are <code>ViewGroup</code>s.

<h2>Kotlin Extension Solution</h2>

Add <code>removeSelf</code> to directly call on a view. If attached to a parent, it will be removed. This makes your code more declarative, and thus readable.

<pre><code>myView.removeSelf()

fun View?.removeSelf() {
 this ?: return
 val parent = parent as? ViewGroup ?: return
 parent.removeView(this)
}
</code></pre>

Here are 3 options for how to programmatically add a view to a <code>ViewGroup</code>.

<pre><code>// Built-in
myViewGroup.addView(myView)

// Reverse addition
myView.addTo(myViewGroup)

fun View?.addTo(parent: ViewGroup?) {
 this ?: return
 parent ?: return
 parent.addView(this)
}

// Null-safe extension
fun ViewGroup?.addView(view: View?) {
 this ?: return
 view ?: return
 addView(view)
}
</code></pre>

How do I add and remove views such as <code>TextView</code>s from Android app like on the original stock Android contacts screen where you press a small icon on the right side of a field and it adds or deletes a field which consists of a <code>TextView</code> and an <code>editTextView</code> (from what I can see).

Any examples on how to achieve this?

如何从Android应用程序中添加和删除视图，比如在原始的Android联系人屏幕上，按下字段右侧的一个小图标，它就会添加或删除一个由TextView和editTextView组成的字段(从我所看到的)。有没有关于如何实现这一点的例子？
