There isin't a hovering tooltip concept in Android. You can do either of the 2 things:

<code>LongClickListener</code> for your <code>EditText</code> which will show a toast when user long presses on it. Something like this:

<pre><code>View view = (View)findViewById(R.id.your_view);
view.setOnLongClickListener(new OnLongClickListener() {
 @Override
 public void onLongClick(View v) {
 Toast toast = Toast.makeText(this, "Show hint here", Toast.LENGTH_SHORT);
 }
});
</code></pre>

OR

Show Hint in the EditText to let users know what do they need to type in.

<pre><code>&lt;EditText
 android:hint="Your tip here" /&gt;
</code></pre>

blocks|key|4413731|text|这可以在EditText上使用OnFocusChangeListener来完成|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4413732|其思想是创建工具提示布局，并在焦点改变时更改其可见性|4413733|您可以使用FrameLayout在普通布局的顶部创建提示布局，也可以只在布局顶部添加工具提示布局。在这两种情况下，可见性都会消失。|4413734|然后使用OnFocusChangeListener显示或隐藏工具提示|4413735|edittxt.setOnFocusChangeListener(new+OnFocusChangeListener()
{
++++@Override
++++public+void+onFocusChange(View+v,+boolean+hasFocus)+
++++{

++++++++++//+Show+tool+tip++
++++++++}else{
+++++++++++//+Hide+tool+tip
++++++++}
++++}
});|code-block|syntax|javascript|4413736|您还可以使用不同的侦听器来增强这一点，比如OnKeyListener|4413737|只是为了提高我的回答|4413738|你也可以使用Android的TextWatcher类，它可以帮助我们对文本的变化做出反应。|offset|length|4413739|有关示例中TextWatcher的用法，请参阅以下内容|4413740|+TextWatcher+textWatcher+=+new+TextWatcher()

This can be done using OnFocusChangeListener on EditText 

The idea is that you will create tool tip layout and will change its visibility on Focus change

You can create tip layout by either top of normal layout using FrameLayout or by just adding tool tip layout at top of your layout. In both these cases visibility will be gone.

Then use OnFocusChangeListener to show or hide tool tip

<pre><code>edittxt.setOnFocusChangeListener(new OnFocusChangeListener()
{
 @Override
 public void onFocusChange(View v, boolean hasFocus) 
 {
 if (hasFocus == true)
 {
 // Show tool tip 
 }else{
 // Hide tool tip
 }
 }
});
</code></pre>

You can also enhance this with different listeners like OnKeyListener

Just to improve my answer

you can also use <a href="http://developer.android.com/reference/android/text/TextWatcher.html" rel="nofollow">TextWatcher</a> Class of Android which facilitates us to react on Text Change.

Please refer following for use of TextWatcher in your example

<pre><code> TextWatcher textWatcher = new TextWatcher()
 {
 @Override
 public void onTextChanged(CharSequence s , int start,int before,int count){

 }
 @Override
 public void afterTextChanged(Editable s){

 }
 @Override
 public void beforeTextChanged(CharSequence s, int start,int count, int after){

 }

 };

 Then use it as 
 edittext.addTextChangedListener(textWatcher);
</code></pre>
