If you mean the location where you will add it in the layout.
You can define a container like a FrameLayout and add this EditText to it when it is created.

<pre><code>&lt;LinearLayout xmlns=".."/&gt;
 &lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/container" android:layout_width="wrap_content"
 android:layout_height="wrap_content" /&gt;
&lt;/LinearLayout&gt;

FrameLayout layout = (FrameLayout) findViewById(R.id.container);
layout.addView(name);
</code></pre>

blocks|key|507949|text|啊，好的。你要找的是setHint(int)。只需从xml传入一个字符串的资源id，就可以了。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|507950|​|507951|📷|atomic|507952|507953|编辑|507954|在可扩展标记语言中，它只是android:hint="someText"|507955|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/4162ff02ebd141fffd977c695a82bfff.png|imageAlt^0|A|C|0|0|0|1|0|0|0|0|D|N|0^^$0|@$1|2|3|4|5|6|7|Y|8|@$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|11|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|12|8|@]|D|@$9|13|A|14|1|15]]|E|$]]|$1|K|3|G|5|6|7|16|8|@]|D|@]|E|$]]|$1|L|3|M|5|6|7|17|8|@]|D|@]|E|$]]|$1|N|3|O|5|6|7|18|8|@$9|19|A|1A|B|C]]|D|@]|E|$]]|$1|P|3|-4|5|6|7|1B|8|@]|D|@]|E|$]]]|Q|$R|$5|S|T|U|E|$V|W|X|-4]]]]

Ah, ok. What you're looking for is <code>setHint(int)</code>. Simply pass in a resource id of a string from your xml and you're good to go.

<h3>EDIT</h3>

And in XML, it's simply <code>android:hint="someText"</code>

blocks|key|508023|text|android:hint="text"为用户提供需要在特定editText中填写的信息|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|508024|例如:-我有两个edittext，一个用于数值，另一个用于字符串值。我们可以为用户设置一个提示，这样他就可以理解他需要给出什么值|508025|android:hint="Please+enter+phone+number"
android:hint="Enter+name"+|code-block|syntax|javascript|508026|运行应用程序后，这两个edittext将显示输入的提示，单击编辑文本后，用户可以输入他想要的内容(参见奢华模式图像)|508027|entityMap^0|0|J|T|8|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|V|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|W|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|X|8|@]|D|@]|E|$]]|$1|O|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|P|$]]

<code>android:hint="text"</code> provides an info for user that what he need to fill in particular <code>editText</code>

for example :- i have two edittext one for numeric value and other for string value . we can set a hint for user so he can understand that what value he needs to give

<pre><code>android:hint="Please enter phone number"
android:hint="Enter name" 
</code></pre>

after running app these two edittext will show the entered hint ,after click on edit text it goes and user can enter what he want (see luxurymode image)

This how to make input password that has hint which not converted to * !!.

On XML : 

<pre><code>android:inputType="textPassword"
android:gravity="center"
android:ellipsize="start"
android:hint="Input Password !."
</code></pre>

thanks to : mango and rjrjr for the insight :D.

If you want to insert text inside your EditText view that stays there after the field is selected (unlike how hint behaves), do this:

In Java:

<pre><code>// Cast Your EditText as a TextView
((TextView) findViewById(R.id.email)).setText("your Text")
</code></pre>



In Kotlin:

<pre><code>// Cast your EditText into a TextView
// Like this
(findViewById(R.id.email) as TextView).text = "Your Text"
// Or simply like this
findViewById&lt;TextView&gt;(R.id.email).text = "Your Text"
</code></pre>

You have to use the android:hint attribute

<pre><code>&lt;EditText
android:id="@+id/message"
android:hint="&lt;&lt;Your placeholder&gt;&gt;"
/&gt;
</code></pre>

In Android Studio, you can switch from XML -> Design View and click on the Component in the layout, the EditText field in this case.
This will show all the applicable attributes for that GUI component.
This will be handy when you don't know about all the attributes that are there.

You would be surprised to see that EditText has more than 140 attributes for customization.

How can I add a <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/Input" rel="noreferrer">placeholder</a> text to <code>EditText</code> in the class that isn't in the XML?

I have the following <code>EditText</code> in my code which will be shown in alertdialog:

<pre><code> final EditText name = new EditText(this);
</code></pre>

Android add placeholder text to EditText

Android Studio

Android

容器

Kotlin

Java

如何向不在中的类中的EditText添加XML？我的代码中有以下EditText，它将显示在shown对话框中：    final EditText name = new EditText(this);
